氣動快裝蝶閥

一、工作原理：  衛(wèi)生級快裝蝶閥是用圓形蝶板作啟閉件并隨閥桿轉(zhuǎn)動來開啟、關(guān)閉和調(diào)節(jié)流體通道的一種閥門。蝶閥的蝶板安裝于管道的直徑方向。在蝶閥閥體圓柱形通道內(nèi)，圓盤形蝶板繞著軸線旋轉(zhuǎn)，旋轉(zhuǎn)角度為0°~90°之間，旋轉(zhuǎn)到90°時，閥門則牌全開狀態(tài)。

二、產(chǎn)品特點：不僅結(jié)構(gòu)簡單、體積小、重量輕、材料耗用省，安裝尺寸小、而且驅(qū)動力矩小，操作簡便、迅速，并且還可同時具有良好的流量調(diào)節(jié)功能和關(guān)閉密封特性。裝蝶閥在*開啟時，具有較小的流阻，當(dāng)開啟在大約15°至70°之間時，又能進(jìn)行靈敏的流量控制，因而在大口徑的調(diào)節(jié)領(lǐng)域，蝶閥的應(yīng)用非常普遍;蝶閥閥板的運(yùn)動帶有擦拭性，因而該焊接蝶閥可用于帶懸浮固定顆粒的介質(zhì)，依據(jù)密封件的強(qiáng)度也可用于粉狀和顆粒狀介質(zhì)。

三、密封：  裝蝶閥屬中線軟密封蝶閥，其密封原理為，閥板加工時保證其密封面具有合適的表面粗造度值，合成橡膠閥座在模壓成型時形成密封面合適的表面粗糙值。閥門關(guān)閉時，通過閥板的轉(zhuǎn)動，閥板的外圓密封面擠壓合成橡膠閥座，使合成橡膠閥座產(chǎn)生彈性變形彈性力作為密封比壓保證閥門的密封。

四、優(yōu)點

1 、蝶閥橡膠密封圈與閥板均采用進(jìn)口件，保證了蝶閥的使用性能和使用壽命。

2 、采用高精度數(shù)控車床精車閥體，保證了蝶閥可靠的互換性，免去了因更換橡膠而不能保證其使用性能的麻煩。

3 、閥桿鑲裝尼龍軸套，減小了磨擦力因而開啟靈活輕松。

4 、鋼件均采用不銹鋼制作，橡膠采用食品橡膠，衛(wèi)生質(zhì)量高。

5 、閥體通徑與管道內(nèi)徑等徑，開啟時窄而呈流線型的閥板與流體方向，流量大而阻力小，無物料積聚。

6 、手柄采用扳動式和拉動式，可承受較大操作力矩，不易扳斷。

7 、開閉范圍為 0~90 度，可固定于每隔 15 度的位置上，具有可調(diào)性，且開閉迅速，操作方便。

8 、閥體均采用可拆連接，結(jié)構(gòu)簡單，維修方便。

9 、造型輕巧美觀，表面光亮而不粘塵，無毛刺扎手。

10 、經(jīng)過嚴(yán)密的強(qiáng)度和密封試驗，保證質(zhì)量。

11 、抽樣進(jìn)行不低于 30000 次的疲勞壽命試驗，保證了其使用壽命。

五、選用原則：  適用于要求達(dá)到*密封、氣體試驗泄漏為零、壽命要求較高、工作溫度在此10℃至150℃的淡水、污水、海水、鹽水、蒸氣、天然氣、食品、藥品、油品和各種酸堿及其他衛(wèi)生級潔凈管路上。

Pneumatic quick installation butterfly valve

1. Working principle: Sanitary quick-install butterfly valve is a valve that uses a circular butterfly plate as an opening and closing part and rotates with the valve stem to open, close and adjust the fluid channel. The butterfly plate of the butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When it rotates to 90°, the valve is fully open.

2. Product features: not only simple structure, small size, light weight, low material consumption, small installation size, small driving torque, easy and fast operation, but also good flow adjustment function and closing sealing characteristics. When the butterfly valve is fully opened, it has a small flow resistance. When it is opened between about 15° and 70°, it can control the flow sensitively. Therefore, in the field of large-diameter adjustment, the application of butterfly valves is very common; butterfly valves The movement of the valve plate is wiping, so the welded butterfly valve can be used for media with suspended fixed particles, and can also be used for powdery and granular media depending on the strength of the seal.

3. Sealing: The butterfly valve is a midline soft-sealing butterfly valve. The sealing principle is to ensure that the sealing surface has a suitable surface roughness value when the valve plate is processed, and the synthetic rubber valve seat forms a suitable surface roughness value of the sealing surface during molding. . When the valve is closed, through the rotation of the valve plate, the outer sealing surface of the valve plate squeezes the synthetic rubber valve seat, so that the synthetic rubber valve seat produces elastic deformation elastic force as the sealing pressure to ensure the sealing of the valve.

Fourth, the advantages: 

1. The rubber sealing ring and valve plate of the butterfly valve are imported parts, which ensures the performance and service life of the butterfly valve.

2. The valve body is precision-turned by a high-precision CNC lathe, which ensures the reliable interchangeability of the butterfly valve and avoids the trouble of not guaranteeing its performance due to the replacement of rubber.

3. The valve stem is inlaid with nylon bushing, which reduces the friction force and makes it flexible and easy to open.

4. The steel parts are all made of stainless steel, and the rubber is made of food rubber, with high hygienic quality.

5. The diameter of the valve body is equal to the inner diameter of the pipeline. When opening, the valve plate is narrow and streamlined and the direction of the fluid is large, the flow is large, the resistance is small, and there is no material accumulation.

6. The handle adopts the pulling type and the pulling type, which can bear a large operating torque and is not easy to be broken.

7. The opening and closing range is 0~90 degrees, and it can be fixed at every 15 degrees. It is adjustable, opens and closes quickly, and is easy to operate.

8. The valve body adopts detachable connection, with simple structure and convenient maintenance.

9. The shape is light and beautiful, the surface is bright and not sticky, and there is no burr.

10. After strict strength and sealing tests, the quality is guaranteed.

11. Sampling for no less than 30,000 fatigue life tests to ensure its service life.

5. Selection principle: It is suitable for fresh water, sewage, sea water, salt water, steam, natural gas, food, medicine, oil that require complete sealing, zero leakage in gas test, high life expectancy, and working temperature between 10°C and 150°C. Products and various acid-base and other sanitary-grade clean pipelines.
