1. For metal corrugated expansion joint Armoured bellows are widely used in various pipeline systems to compensate axial, lateral and angular displacement caused by temperature and pressure fluctuations. The core component of the armored bellows is the bellows, which can carry out pumping, lateral and angular displacement through the deformability and pressure resistance of the bellows, and bear t...
The armored corrugated pipe is characterized by corresponding displacement under the action of pressure, axial force, transverse force or bending moment, pressure resistance, vacuum sealing, corrosion resistance, temperature stability and long service life. Therefore, it is widely used in many industrial fields. Various pipes are often used in daily life, among which armored corrugated pipes are w...
Armored corrugated pipes refer to expandable tubular products made of plastic. Plastic corrugated pipes save materials, are light in weight, and have excellent physical and chemical properties. They are widely used in civil buildings, municipal projects, and highway bridges. The armored corrugated pipe is a corrugated pipe. The common metal corrugated pipe is carbon steel. The stainless steel or i...
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...
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...
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...
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...
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...
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...
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...
