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...
Metal bellows accumulators are advanced technologies available for hydraulic systems, preferably for reducing or smoothing pressure peaks in pressure fluids. In order to ensure that the separating bellows can move freely and there is no risk of damaging its corresponding working position during operation, the outer diameter of the bellows is selected to be slightly smaller than the inner diameter ...
The outer diameter of the bellows accumulator can be advantageously selected to be smaller than the distributable inner diameter of the accumulator shell, so as to form a plurality of Subspaces in the fluid space, and the subspace as a whole forms a hydraulic buffer of the fluid. Advantageously, the sealing device can be arranged on the closed part between the guide device and the cover. In additi...
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...
What are the main types of bellows accumulators? 1. Hammer accumulator The hammer accumulator stores and releases energy by changing the position of the heavy hammer to the north. The heavy hammer exerts a certain pressure on the hydraulic fluid through the plunger. The accumulator has the advantages of simple structure, hidden pressure, small capacity, low pressure, large size, heavy weight, larg...
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...
