Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] refer to Figure 1 to Figure 7 As shown, a two-position five-way isolation solenoid valve includes a coil assembly 11 and a valve body 12 connected thereto. The valve body 12 is provided with a valve cavity 121 for accommodating a valve core 13, and the valve core 13 is connected to the valve body 12. There is a gap between the valve chambers 121, the iron core assembly 111 and the ejector rod 112 control the up and down movement of the valve core 13, and the valve core 13 is provided with four circumferential seals 131, and these four circumferential seals 131 seal the valve The cavity 121 is divided into five sections, and the side wall of each valve cavity is provided with a flow channel 15 communicating with the outside world, and the uppermost flow channel and the lowermost flow channel are connected through the inner flow...

Abstract

A two-position five-way isolated electromagnetic valve comprises a coil assembly and a valve body connected with the coil assembly. A valve cavity is arranged in the valve body and used for containing a valve element. A gap exists between the valve element and the valve cavity. An iron core assembly and an ejector rod control the valve element to move up and down. The valve element is provided with a plurality of circumferential seal pieces. The valve cavity is divided into five segments by the circumferential seal pieces. The side wall of each segment of the valve cavity is provided with a flow channel communicating with the external world. The flow channel at the upper end and the flow channel at the lower end communicate with each other through an inner flow channel and are used for flow of a medium. A cavity is arranged inside the valve element. The side wall of the valve element is provided with a through hole. A seal ring is arranged on the periphery of the ejection rod. By the adoption of the two-position five-way isolated electromagnetic valve, the isolation effect between a medium cavity and the coil assembly is good, and different states of the flow channels can be achieved through movement of the multiple circumferential seal pieces. The two-position five-way isolated electromagnetic valve is wide in application range, high in strength and long in service life, and the valve element is convenient to assemble.

Description

technical field [0001] The invention belongs to the field of solenoid valves, in particular to a two-position five-way isolation solenoid valve. Background technique [0002] Solenoid valve is an automatic actuator based on electromagnetic control in industrial equipment. It is often used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. The working principle of the solenoid valve is to use the energized coil to generate electromagnetic force, drive the iron core to drive the valve core to move, realize the opening and closing of the valve, change the flow state of the fluid, and achieve the purpose of control. [0003] Solenoid directional valve is a kind of solenoid valve. Through the cooperation of movable spool and multi-channel, different medium flow states can be realized. Therefore, electromagnetic directional valve is widely used in construction machinery and electrical equipment. Most of the current electromagnet...
