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] Describe the embodiment of this solenoid valve in detail below according to accompanying drawing:

[0025] Such as figure 1 and 2 As shown, the patent of the present invention consists of a valve body 1, a first liquid hole 2, a second liquid hole 3, an inner cavity 4, a gasket 5, a sealing ring 6, a sliding ring 7, a coil body 8, a rubber ring 9, a wire 10, Components such as spring 11, sliding iron core 12, sensor 13 constitute. The valve body has an inner cavity, the central hole through which the first liquid hole communicates with the inner cavity is blocked by a gasket, and the central hole of the second liquid hole directly communicates with 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 through bolts, and the coil body is provided with wires connected to the power supply. A sliding ring is embedded inside the coil body, a sliding iron core is installed in ...

Abstract

The invention discloses an electromagnetic valve for hemodialysis. The electromagnetic valve for hemodialysis mainly structurally comprises a valve body provided with an inner cavity, an extendable sliding iron core is mounted in the inner cavity of the valve body, and the upper end of the iron core and a top coil of the inner cavity are fixed while the lower end of the iron core is connected with a sealing gasket to drive the sealing gasket to move up and down and control the valve to open and close. The electromagnetic valve for hemodialysis has the advantages of low power consumption, small size, excellent corrosion resistance, no medium leakage, easiness in cleaning, simplicity in operation, convenience in mounting and capability of making an electromagnetic system high in switching speed, rapid to respond and high in efficiency.

Description

[0001] 【Technical field】 [0002] The patent of the present invention relates to the technical field of solenoid valves, 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 fluid passage. Commonly used solenoid valves are composed of valve body, coil body, sliding iron core and other components. The electromagnetic action of the coil body and the sliding iron core directly controls the movement of the plug up and down, thereby realizing the opening and closing of the orifice. The existing shortcomings are: [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 easily corroded and rusted by liquid, and is easy to cause medical liqu...
