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...
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...
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...
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...
The left end of the bellows accumulator is welded with the flange of the hydraulic pipeline interface, the right end of the bellows is welded with the seal ring, and the right side of the seal ring is also provided with a guide ring. Corrugated pipes are installed in the original accumulator shell, which can be deformed after being pressed, absorb the pulsating pressure in the pipeline, ensure tha...
