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...
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 ...
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...
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...
As we all know, 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. Its sealing directly affects the performance of self operated control valves. Therefore, to improve the performance of special valves, it is necessary to continuously improve their sealing performance in use. Here are some ways to improve the...
