Problems solved by technology

[0005] 1. When the solenoid valve is opened and closed, the noise is increased because the sliding iron core directly contacts the bottom of the coil
[0006] 2. The valve body is usually made of metal material, which is easy to be corroded and rusted by liquid, and it is easy to cause medical liquid pollution
[0007] 3. When the solenoid valve is opened and closed, the valve is easy to close incompletely, causing the leakage of medical liquid, and it is impossible to detect the leakage of the solenoid valve

Embodiment Construction

[0024] The following describes the embodiments of the solenoid valve in detail according to the drawings:

[0025] Such as figure 1 with 2 As shown, the present invention consists of valve body 1, first liquid hole 2, second liquid hole 3, inner cavity 4, sealing gasket 5, sealing ring 6, sliding ring 7, coil body 8, rubber ring 9, wire 10, spring 11. Sliding iron core 12, sensor 13 and other components. The valve body is provided with an inner cavity, the central hole through which the first liquid hole and the inner cavity pass is blocked by a sealing gasket, and the central hole of the second liquid hole directly penetrates the inner cavity.

[0026] From figure 1 It can be seen that the coil body is located above the valve body and is fixedly connected to the valve body by bolts, and the coil body has its own wire for connecting the power supply. A sliding ring is embedded in the coil body, a sliding iron core is installed in the sliding ring, and the sliding iron core and the...

Abstract

The invention discloses an electromagnetic valve for hematodialysis. The main structure of the electromagnetic valve comprises a valve body, and the valve body is provided with an inner cavity; a telescopic sliding iron core is installed in the inner cavity of the valve body, the upper end of the telescopic sliding iron core and a coil arranged on the top of the inner cavity are fixed, the lower end of the telescopic sliding iron core is connected with a sealing pad, and the sealing pad is driven to vertically move to control the valve to be switched on and switched off. The electromagnetic valve is low in power dissipation and small in size, has the good corrosion resistance, can not cause medium leakage and is easy to clean and operate and convenient to install, and an electromagnetic system is high in switching speed, response speed and efficiency.

Description

[0001] 【Technical Field】 [0002] The invention relates to the technical field of solenoid valves, and in particular to a solenoid valve for hemodialysis equipment. [0003] 【Background technique】 [0004] The solenoid valve is an important part of the hemodialysis equipment, mainly used to control the conduction or disconnection of the liquid passage. Commonly used solenoid valves are composed of valve body, coil body, sliding iron core and other parts. Through the electromagnetic action of the coil body and sliding iron core, the plug is directly controlled to move up and down to realize the opening and closing of the orifice. The disadvantages are: [0005] 1. When the solenoid valve is opened and closed, the sliding iron core directly contacts the bottom of the coil, which increases the noise. [0006] 2. The valve body is usually made of metal material, which is easy to be corroded and rusted by liquid, and it is easy to cause medical liquid pollution. [0007] 3. When the solenoid ...
