进口防水电磁阀哪家品牌好

进口防水电磁阀Product Description:

The utility model belongs to the technical field of control valves. A waterproof solenoid valve comprises a barrel shaped waterproof shell with a spiral channel along the axial direction in the wall body, a waterproof cover is arranged at the barrel opening of the waterproof shell, at the same time, the valve rod of the valve body extends into the waterproof shell through the waterproof cover, and two connectors are arranged on the outer wall and inner wall of the waterproof shell, and the two connectors on each side are respectively connected with both ends of the spiral channel; Heat the waterproof shell by threading a heating component in the spiral channel, and supplement the gap formed by the cold shrinkage of the waterproof cover through the wall thickness expansion of the waterproof shell in the cold temperature environment to prevent the waterproof failure; The spiral channel can also be connected to the cooling water circulating device to cool the waterproof shell. In the high temperature environment, the expansion and extrusion caused by the thermal expansion of the waterproof cover can be avoided through the cold shrinkage of the wall thickness of the waterproof shell, so as to prevent the waterproof failure caused by the damage of the shell. The security is higher and the waterproof performance is better.

进口防水电磁阀characteristic:

As a kind of solenoid valve, waterproof solenoid valve is installed on the pipe immersed in liquid because of its waterproof property. As it is immersed in liquid for a long time, for the waterproof solenoid valve used outdoors, the temperature of the liquid also changes with the change of seasons, resulting in the problem of thermal expansion and cold contraction of the valve of the waterproof solenoid valve, which is easy to cause the sealing failure of the sealing area, and thus the waterproof solenoid valve is damaged due to the internal water inflow of the waterproof solenoid valve.

进口防水电磁阀Principle:

The wall of the waterproof shell of the waterproof solenoid valve is provided with a spiral channel along its axis, and a heating component is arranged in the spiral channel, which solves the problem of sealing failure caused by the shrinkage of the waterproof cover in the cold and warm environment, or connects the spiral channel with the cooling water to prevent the expansion and extrusion between the waterproof shell and the waterproof cover due to the expansion of the waterproof shell in the high temperature environment, For the problem of water-proof failure caused by shell damage, appropriate structural components can be selected according to the service environment, which effectively prevents the problem of water-proof failure caused by thermal expansion and cold contraction caused by the change of service environment temperature, and has higher safety guarantee and adaptability.
