Where should the check valve be installed? Did you pretend it right?Today we will discuss the installation location of the check valve. So how to determine the installation position of the check valve? What is the difference between the installation of the check valve before the pump and the installation of the check valve after the pump, and where does the installation before the pump apply? Check valves are usually used in conjunction with other valves. When used in conjunction with other valves, where should the check valves be installed? Let’s discuss it together.Check valve, also called check valve, is an automatic valve. It relies on the pressure of the flowing medium in the pipeline to push the disc to close and open the valve. When the medium stops flowing, the check valve disc closes, it can be effective Prevent the medium in the pipeline from flowing back, which plays a great role in ensuring…

The principle of the balance valve is the anti-regulation in the valve body. When the pressure at the inlet increases, the diameter is automatically reduced to reduce the change of flow, and vice versa. If the connection is reversed, this adjustment system will not work. Moreover, the regulating valve is directional, and the reverse pressure can even reduce or even close the flow. Since the balance valve is installed for better heating, there is no problem of reverse installation. If it is a reverse installation, it is a human error, and of course it will be corrected. Balance valve belongs to the category of regulating valve. Its working principle is to change the flow resistance of fluid flowing through the valve by changing the gap between the valve core and the valve seat (that is, the opening) to achieve the purpose of adjusting the flow rate. The balance valve is equivalent to a throttling element whose…

  Marine valves are equipment that controls the pressure, flow and flow direction of the fluid in the ship’s pipes in order to meet the environmental conditions of the ship. A valve is a control device for a fluid pipeline. The basic function is to open or block the flow of the pipeline medium, change the flow direction of the medium, adjust the pressure and flow of the medium, and protect the normal operation of the pipeline equipment. Overview of Marine Valve Technology Development     Since the birth of the People’s Republic of China, my country’s marine valve technology has achieved rapid development. Through the transfer of early Soviet products, major auxiliary sintering, serialization and standardization, and self-research and design, it has basically met the needs of my country’s shipbuilding industry. A total of 12 universal valves have been designed. Category, 1400 specifications. The maximum pressure of the valve is 25MPa, and the maximum diameter…
