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...
Seal selection parameters: medium pressure, temperature, shaft diameter and speed. The selection of mechanical seal structure type is an important step in the design process, and must be investigated first: (1) working parameters - medium pressure, temperature, shaft diameter and speed. (2) medium characteristics a concentration, viscosity, corrosion, whether there are solid particles and fiber im...
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 ...
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...
