Unidirectional solenoid valve common several coupling forms explained

One-way solenoid valve variety, and play a key role in the filter separator, generally according to the duties of the pipeline solenoid valve. Structure way. Promote the way. Material and application areas for classification, the text describes a few common one-way solenoid valve connection.

1. Live sleeve flange

This is also the gate valve using more connection. Solar one-way solenoid valve according to the combination of surface pattern can be divided into the following categories.

1) smooth: for the working pressure of the lower gate valve. Production and manufacturing is more convenient

2) Convex: higher working pressure, the use of hardened gaskets

3) tongue and groove body type: can be used with plastic deformation of the larger gasket, in the leaching material is more widely used, sealing the actual effect is good.

4) trapezoidal groove body type: with an oval metal ring for the gasket, used for working pressure ≥ 64KG / cm3 gate valve, or hydraulic pressure one-way solenoid valve.

5) lens type: gasket is a lens mold, made of metal materials. Used for working pressure ≥ 100KG / ccm of Koran gate valve, or high-temperature valves.

6) O-ring type: This is also a newer way to live flange, which is accompanied by a variety of rubber materials o-ring generation, and the rapid development of his actual effect in sealing than the general flat gasket reliable.

2. Flange connection

This is also a simple connection method, mostly seen in small gate valve. And divided into 2 kinds of cases.

1) Immediately sealed: the inner and outer pipe threads immediately play a sealing role. In order to facilitate to ensure that the joint does not leak, generally with lead oil. Line hemp and polytetrafluoroethylene raw tape filling; in which polytetrafluoroethylene raw tape, the use of increasingly widespread; this raw material corrosion resistance is very good, overdrive gear one-way solenoid valve sealing the actual effect is very good, easy to apply and store, disassembly, you can take it out in detail, because it is a non-consuming sticky plastic film, than lead oil. Line hemp outstanding much.

2) indirect sealing: pipe thread tightening energy, transmission to the two planes between the gasket, so that the gasket to play a sealing role.
