In fact, the piston valve is a common building material device in our lives, and it is widely used in many places. It is generally installed in the corners of the wall, such as the factory's large-scale mechanical equipment and some small air pumps. So then we have to explain specific features on the piston valve and piston valve works and related content applications. Piston valve features 1. First of all, we have come to understand some relevant features of the piston valve. Its characteristic in design is that it is suitable for the fluid regulation requirements in different fields in various factories and it has good anti-cavitation characteristics. Due to its relatively good sealing system and relatively long use time, this piston valve uses metal and elastomer as the seal, so it is closed tightly. In addition, this device also has a pressure balanced drive, so when operating, the corresponding operating force can be adjusted according to different operating conditions. 2. There are many characteristics of the piston valve. Next, we will learn more about it. For example, if the amount of water is large and the cavitation is very light, the cavitation will be the weakest if the outlet components use the L-shaped porous ring network. The type of the outlet valve can be changed to change the flow characteristics. The contact closure valve is used to seal the seal ring. The seal is good. The valve seal ring is only pressed without friction, so it has little wear and long service life. 3, the pressure inside the piston valve will be more uniform, and it requires no driving force, and the gate valve, ball valve are not the same, the role of the valve seat surface water pressure on both sides without direction. The water pressure on both sides of the piston valve upstream and downstream is exactly in the opposite direction, and the force acting on the sealing surface is the pressure difference on both sides. The piston travel distance is short, the valve body is a cylindrical section, so it occupies a small space, large ring stiffness, and good resistance to water pressure. Piston valve working principle and application 1, principle So most of people don't know about the working principle of the piston valve, so it's easy to share some of the following, when the water flow through the axial arc into the shell of the valve. Regardless of the position of the piston, the corresponding flow cross section in all positions within the valve chamber will exhibit a ring shape. We can also see that the axis is shrinking at the exit, so that it can be avoided very well because the cavitation caused by the throttling will damage the valve body and the corresponding pipeline. At the same time, its adjustment characteristic is linear, and its corresponding standard size is DN150 to DN1200. 2, application In terms of diversion, the piston valve can be used inside the system instead of the relief valve. Then I must pay attention to an annular venting device. Of course, the piston valve can also be used as an explosion-proof valve. The storage aspect of the piston valve can be completely used for the liquid level and pressure regulating valve. The water delivery can also be used for the flow regulating valve, or it can be used when the net valve and the irrigation valve are used. In terms of water treatment or sewage treatment, the piston valve can be used as a pump start protection valve or used as a corresponding gas volume control valve of a sewage treatment plant. The above features about the piston valve , as well as the related content of the piston valve working principle and application are introduced here. I hope this helps everyone.
