There Are Three Sealing Parts Of The Instrumentation Valves

Jul 04, 2017

The Instrumentation Valves is a pipe accessory. It is a device used to change the flow path and the flow direction of the medium and to control the flow of the conveying medium. The sealing performance of the Instrumentation Valves is the ability of the sealing parts of the Instrumentation Valves to prevent the media from leaking. It is the most important technical performance index of the Instrumentation Valves. There are three sealing parts of the Instrumentation Valves: the opening and closing parts and the valve seat between the two sealing surface contact; packing and stem and packing material with the Department; valve body and the lid of the connection. One of the former leak is called the internal leakage, which is usually said lax, it will affect the Instrumentation Valves cut off the ability of the media. For the cut-off valve class, the internal leakage is not allowed. After the two leaks called leakage, that is, the media leak from the valve to the valve outside.

Instrumentation Valves interface size and form:

Instrumentation Valves are two-way and three-way, can be applied to a variety of common occasions, can also be used in dashboard. The valve model is complete, to achieve the closure of the seal, long service life, operating torque is small.

1, Instrumentation Valves interface size

Instrumentation Valves interface size of 1/4 "to 1." Three-piece large flow ball valve configuration CF8M stainless steel precision casting body and CF3M stainless steel precision casting end cap, the size is extremely accurate, high surface finish.

2, instrumentation valves in two forms

Instrumentation Valves products are available in two forms: linear structure and angle structure, the material is stainless steel and copper. The valve body design and structure of durable.

3, the use of Instrumentation Valves

(1) Turn on or cut off the media in the pipe. Such as gate valve, globe valve, ball valve, plug valve, diaphragm valve, butterfly valve and so on.

(2) to regulate and control the flow and pressure of the medium in the pipeline. Such as throttle, regulating valve, pressure reducing valve, safety valve and so on.
