產(chǎn)品結(jié)構(gòu)特點(diǎn) Construction features

伸縮閥適用于溫度≤425℃，公稱壓力≤1.6MPa的食品、醫(yī)藥、化工、石油、電力、輕紡、造紙等給排水、氣體管道上作調(diào)節(jié)流量和截流介質(zhì)的作用，具有補(bǔ)償管道熱脹冷縮的功能。

其主要特點(diǎn)為：

1、設(shè)計(jì)新穎、合理，結(jié)構(gòu)，重量輕，操作方便，啟閉迅速；

2、伸縮蝶閥除了能作調(diào)節(jié)和截流作用，補(bǔ)償管道溫差所產(chǎn)生的熱脹冷縮功能外，還能為安裝更換、維修閥門提供方便；

3、密封部位可調(diào)節(jié)更換，密封性能可靠等特點(diǎn)。

Expansion valve is suitable for the temperature of 425℃ or less and nominal pressure of 1.6 MPa or less food, medicine, chemical, petroleum, electric power, textile,paper and other water supply and drainage, for adjusting flux on the gas pipeline and intercepting the role of the media, has the function of compensating pipe heat bilges cold shrink.

Its main features are:

1. The design is novel and reasonable, the structure is unique, the weight is light,

the operation is convenient, the opening and closing fast;

2. In addition to adjusting and intercepting the butterfly valve, it can also provide convenient installation and replacement and maintenance of valve.

3. The sealing parts can be adjusted and replaced, and the sealing performance is reliable.
