What are the inspections of special valves before they are put into the market? During theproduction of special valves such as high pressure special valves and before they are put into the market, relevant tests shall be carried out to ensure the quality of special valves. Through testing, we can find out the problems of special valves and eliminate products with poor quality. So, what are theinsp...
As we all know,corrosion resistant special valves rely on the pressure and temperature of the medium in the valve as the energy source to drive the valve to work automatically, and its sealing directly affects the service performance of the self operated regulating valve. Therefore, in order to improve the service performance of special valves, it is necessary to continuously improve its sealing p...
Armored bellows are tubular elastic sensors connected along the folding and stretching direction by folding bellows. Bellows are widely used in instruments and meters. The main purpose is to convert pressure into displacement or force as a measuring element of pressure measuring instrument. Armoured bellows have thin walls and high sensitivity, ranging from tens of pascals to tens of megabascals. ...
Bellows elastic sensor connected with foldable ripples along the direction of folding expansion. Bellows are widely used in instrumentation, the main purpose is as a pressure detector measuring element, the pressure into displacement or force, the following understanding of the preparation method and process of armored bellows. Armoured bellows have at both ends with anchor plate is inserted into ...
The selection of special valves is an important factor for the correct use of special valves. In many cases, users will encounter various problems when using special valves, and often find that the specification and model are not selected properly. What should be paid attention to in the selection of special valves? 1、 Ensure longer service life Continuous service life is a parameter that should b...
Special valve is a very important protection valve, which is widely used in various pressure vessels and pipeline systems. When the pressure in the pressurization system exceeds the specified value, it can be automatically opened to discharge the excess medium into the atmosphere to ensure the safe operation of the pressure vessel and pipeline system and prevent accidents. When the pressure in the...
During the installation and use of special valves, in order to achieve better application, it is necessary to pay attention to whether the installation mode of products is reasonable, because the installation effect of devices directly affects the actual application. When installing and using special valves, keep a certain distance from the ground. If the special valve is too close to the ground d...
The bellows type accumulator reaches the pull-out end of the bellows due to the main pre filling pressure, and the sealing device of the guide device blocks the fluid space outside the bellows. Through the closed fluid volume, the bellows is therefore supported against the pre filling pressure acting from the internal space, and is therefore prevented from being damaged in case the pre filling pre...
