良工閥門：一眼辨開關(guān)，告別供暖誤操作！萬能判斷法 + 專業(yè)規(guī)范全解析

　　Lianggong Valve: One glance identification switch, say goodbye to heating misoperation! Universal judgment method+comprehensive analysis of professional standards

　　每年供暖季啟停階段，超 70% 家庭因分不清暖氣閥門開關(guān)狀態(tài)，導(dǎo)致供暖不熱、停暖后管道缺水銹蝕，成為暖通系統(tǒng)高頻故障誘因。作為暖通管路控制核心部件，良工閥門以標(biāo)準(zhǔn)化設(shè)計與清晰標(biāo)識，讓閥門狀態(tài)判斷 “一看就懂、一學(xué)就會”，徹底解決用戶 “辨閥難、操作錯” 的痛點，守護(hù)家庭供暖系統(tǒng)穩(wěn)定運行。

　　During the start and stop stages of the heating season each year, over 70% of households fail to distinguish the status of the heating valve, resulting in heating failure, water shortage, and corrosion of pipelines after heating is stopped, which becomes a high-frequency fault cause for the HVAC system. As the core component of HVAC pipeline control, Lianggong Valve adopts standardized design and clear labeling to make valve status judgment "easy to understand and learn", completely solving the pain points of users' "difficult valve identification and incorrect operation", and safeguarding the stable operation of home heating systems.

　　一、萬能判斷法：手柄辨狀態(tài)，良工閥門通用無誤差

　　1、 Universal judgment method: Handle identification of status, universal error free for Lianggong valves

　　家用暖氣系統(tǒng)中，球閥、溫控閥是主流配置，良工閥門嚴(yán)格遵循行業(yè)通用設(shè)計規(guī)范，狀態(tài)判斷無需專業(yè)知識，僅看手柄與管道角度即可精準(zhǔn)識別：

　　In household heating systems, ball valves and temperature control valves are mainstream configurations. Lianggong valves strictly follow industry standard design specifications, and state judgment does not require professional knowledge. Accurate identification can be achieved by simply looking at the angle between the handle and the pipeline

　　開啟狀態(tài)：手柄與管道軸線完全平行、呈一條直線，閥門內(nèi)部閥芯通孔與管路對齊，熱水可順暢流通，供暖系統(tǒng)正常循環(huán)。

　　Open state: The handle is completely parallel to the axis of the pipeline, in a straight line. The internal valve core hole of the valve is aligned with the pipeline, allowing for smooth flow of hot water and normal circulation of the heating system.

　　關(guān)閉狀態(tài)：手柄與管道軸線呈 90° 垂直交叉，閥芯通孔阻斷水流通道，徹底切斷熱水供應(yīng)，實現(xiàn)管路封閉。

　　Closed state: The handle intersects with the pipeline axis at a 90 ° angle, and the valve core through-hole blocks the water flow channel, completely cutting off the hot water supply and achieving pipeline closure.

　　無論閥門安裝方向、外觀造型如何變化，該規(guī)則均適用。良工閥門全系產(chǎn)品均強化手柄與管道的角度辨識度，部分型號增設(shè) “OPEN（開）”“SHUT（關(guān)）” 字母標(biāo)識及水流箭頭，雙重保障用戶快速判斷，杜絕誤操作。

　　This rule applies regardless of changes in the installation direction and appearance of the valve. All products of Lianggong Valve have strengthened the angle recognition between the handle and the pipeline, and some models have added "OPEN" and "SHUT" letter markings and water flow arrows to double guarantee users' quick judgment and prevent misoperation.

　　二、分類操作指南：良工閥門不同類型，規(guī)范操作更省心

　　2、 Classification operation guide: Lianggong valves of different types, standardized operation is more worry free

　　1. 手柄式球閥（最常用）

　　1. Handle type ball valve (most commonly used)

　　良工手柄式球閥采用 90° 旋轉(zhuǎn)快開結(jié)構(gòu)，操作便捷、密封可靠：

　　The Lianggong handle type ball valve adopts a 90 ° rotating quick opening structure, which is easy to operate and has reliable sealing:

　　開啟：將手柄扳至與管道平行位置，聽到 “咔噠” 定位聲，即為完全開啟。

　　Open: Pull the handle to a position parallel to the pipeline and hear a "click" positioning sound, which means it is fully open.

　　關(guān)閉：順時針旋轉(zhuǎn)手柄 90° 至與管道垂直，確保閥門完全閉合，無滲漏風(fēng)險。

　　Close: Rotate the handle clockwise 90 ° to be perpendicular to the pipeline, ensuring that the valve is fully closed and there is no risk of leakage.

　　適用場景：暖氣片進(jìn)水閥、回水閥、地暖分水器總閥、入戶主管路閥。

　　Applicable scenarios: radiator inlet valve, return valve, underfloor heating water distributor main valve, household main pipeline valve.

　　2. 旋鈕式溫控閥

　　2. Knob type temperature control valve

　　良工溫控閥配備數(shù)字刻度（0-5）及雪花、太陽標(biāo)識，兼顧開關(guān)與流量調(diào)節(jié)：

　　Lianggong temperature control valve is equipped with a digital scale (0-5) and snowflake and sun markings, taking into account both switch and flow regulation:

　　開啟：逆時針旋轉(zhuǎn)旋鈕至數(shù)字 “5” 或太陽標(biāo)識，為最大開啟狀態(tài)。

　　Open: Rotate the knob counterclockwise to the number "5" or the sun symbol for maximum open state.

　　關(guān)閉：順時針旋轉(zhuǎn)旋鈕至數(shù)字 “0” 或雪花標(biāo)識，徹底關(guān)閉（雪花檔多為防凍微開，非全閉）。

　　Close: Rotate the knob clockwise to the number "0" or the snowflake symbol to completely close (snowflake mode is mostly slightly open for antifreeze, not fully closed).

　　適用場景：單組暖氣片支路控溫閥，精準(zhǔn)調(diào)節(jié)室內(nèi)溫度。

　　Applicable scenario: Single set radiator branch temperature control valve, accurately adjusting indoor temperature.

　　3. 手輪式閘閥（老式系統(tǒng)）

　　3. Handwheel gate valve (old system)

　　良工手輪閘閥采用升降式閥芯設(shè)計，旋轉(zhuǎn)多圈實現(xiàn)啟閉：

　　The Lianggong handwheel gate valve adopts a lifting valve core design, which rotates multiple times to achieve opening and closing:

　　開啟：逆時針旋轉(zhuǎn)手輪，閥桿逐漸升高，直至無法轉(zhuǎn)動，為完全開啟。

　　Opening: Rotate the handwheel counterclockwise to gradually raise the valve stem until it cannot be turned, indicating full opening.

　　關(guān)閉：順時針旋轉(zhuǎn)手輪，閥桿下降至底部，徹底阻斷水流。

　　Close: Rotate the handwheel clockwise to lower the valve stem to the bottom, completely blocking the water flow.

　　適用場景：老舊集中供暖系統(tǒng)主管路控制。

　　Applicable scenario: Main pipeline control of old central heating systems.

　　三、停暖關(guān)鍵：良工閥門規(guī)范關(guān)閉順序，延長系統(tǒng)壽命

　　3、 Key to stopping heating: Standardize the closing sequence of Lianggong valves to extend the system's lifespan

　　停暖后閥門操作不僅是關(guān)閉，順序錯誤會導(dǎo)致管道缺水、進(jìn)空氣，銹蝕速度提升 3 倍。良工閥門結(jié)合暖通行業(yè)標(biāo)準(zhǔn)，給出專業(yè)操作流程：

　　After the heating is stopped, the valve operation is not only closed, but the wrong sequence can cause water shortage and air intake in the pipeline, and the corrosion rate will increase by three times. Lianggong Valve combines HVAC industry standards and provides professional operating procedures:

　　先關(guān)回水閥：找到暖氣片下方或分水器回水端閥門，扳至與管道垂直，阻斷回水流通。

　　First, close the return valve: find the valve below the radiator or at the return end of the water divider, turn it to be perpendicular to the pipeline, and block the flow of return water.

　　再關(guān)供水閥：待回水閥完全閉合后，關(guān)閉供水端閥門，形成滿水封閉腔體。

　　Close the water supply valve again: After the return valve is completely closed, close the valve at the water supply end to form a fully sealed chamber.

　　嚴(yán)禁放水排氣：關(guān)閉后勿動排氣閥，良工閥門密封性能可長效鎖水，實現(xiàn)滿水保養(yǎng)，延長管道、暖氣片壽命 5-8 年。

　　It is strictly prohibited to discharge water and exhaust: Do not move the exhaust valve after closing it. The sealing performance of the valve can lock water for a long time, achieve full water maintenance, and extend the service life of pipelines and radiators by 5-8 years.

　　四、良工閥門：專業(yè)品質(zhì)，從源頭減少操作困擾

　　五、常見誤區(qū)提醒：良工閥門教你避坑

　　5、 Common Misconception Reminder: Lianggong Valve teaches you to avoid pitfalls

　　誤區(qū)：手柄半開半閉調(diào)節(jié)溫度 —— 良工球閥為通斷型閥門，非節(jié)流設(shè)計，半開易導(dǎo)致閥芯磨損、漏水，控溫建議使用專用溫控閥。

　　Misconception: The handle is half open and half closed to regulate temperature - Lianggong ball valves are on-off valves with non throttling designs. Half open valves can easily cause valve core wear and water leakage. It is recommended to use specialized temperature control valves for temperature control.

　　誤區(qū)：閥門擰不動強行掰 —— 遇卡頓可滴少量潤滑油，切勿用扳手蠻力操作，良工閥門質(zhì)保期內(nèi)非人為損壞可免費更換。

　　Misconception: If the valve cannot be turned and forcefully breaks, a small amount of lubricating oil can be dripped in case of jamming. Do not use a wrench to operate it forcefully. Lianggong valves can be replaced free of charge during the warranty period if they are not damaged by human factors.

　　誤區(qū)：停暖后不關(guān)閥門 —— 管道與外網(wǎng)連通，易導(dǎo)致水體流失、進(jìn)灰進(jìn)氣，良工閥門建議停暖后必關(guān)進(jìn)出水閥。

　　Misconception: Not closing the valve after stopping the heating process - connecting the pipeline to the external network can easily lead to water loss, ash intake, and air intake. Lianggong Valve recommends closing the inlet and outlet valves after stopping the heating process.

　　閥門雖小，卻是供暖系統(tǒng)的 “控制中樞”。良工閥門以標(biāo)準(zhǔn)化設(shè)計、清晰化標(biāo)識、高品質(zhì)制造，讓暖氣閥門開關(guān)狀態(tài)一目了然、操作簡單規(guī)范，從判斷到操作全程無憂，既保障供暖季穩(wěn)定供熱，又做好停暖后系統(tǒng)保養(yǎng)，為家庭溫暖生活筑牢每一道防線。

　　Although the valve is small, it is the "control center" of the heating system. Lianggong Valve adopts standardized design, clear labeling, and high-quality manufacturing, making the heating valve switch status clear at a glance and easy to operate in a standardized manner. From judgment to operation, the entire process is worry free, ensuring stable heating during the heating season and maintaining the system after the heating is stopped, laying every line of defense for a warm home life.
