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.

The content of the invention
It is not enough for prior art, the invention provides a kind of two five logical isolation solenoid valves, good airproof performance, service life
It is long.
In order to solve above-mentioned technical problem, the present invention is addressed by following technical proposals.
A kind of two five logical isolation solenoid valves, including coil block and the valve body being attached thereto, in the valve body use is provided with
In the valve pocket for accommodating valve element, there is space between the valve element and valve pocket, core assembly and push rod control the up and down motion of valve element,
The valve element is provided with several circumferential seals, and valve pocket is separated into five sections, and every section of valve pocket by this several circumferential seal
Side wall is provided with the runner communicated with the external world, and is connected by inner flow passage between the runner of upper and lower ends, for flow of media；Institute
State valve core inside and be provided with cavity, and the side wall of valve element is provided with through hole；The periphery of the push rod is provided with sealing ring.
In electromagnetic valve in the present invention, sealing ring can be effectively isolated valve pocket and coil block, prevent medium from entering into line
In coil assembly, it is to avoid the damage of coil block.Simultaneously the circumferential seal on valve element plays a part of to seal and separate valve pocket,
The switching of runner during for working.During work, moving up and down for valve element can realize the closing of different runners and connect, and realize not
Congenerous.
Preferably, the valve element includes the upper valve core and bottom spool of molding assembly, between the upper valve core and bottom spool
It is provided with spring, there is provided restoring force is used to lift valve element.
Preferably, the screw thread of cooperation is provided between the bottom of the bottom spool and the bottom of valve pocket, therefore bottom spool
Play a part of bottom flange.
The valve element is provided with least four circumferential seals.
Compared with prior art, the invention has the advantages that：There is provided a kind of two five logical isolation solenoid valves, valve
Isolation effect is good between body dielectric cavity and coil block, while by the movement of the multiple circumferential seals of valve element, it is possible to achieve no
Applied widely with runner state, intensity is high, long service life, and valve element is easy to assembly.

Specific embodiment
Below in conjunction with the accompanying drawings the present invention is described in further detail with specific embodiment.
Referring to figs. 1 to shown in Fig. 7, a kind of two five lead to isolation solenoid valve, including coil block 11 and the valve being attached thereto
Body 12, is provided with the valve pocket 121 for accommodating valve element 13 in the valve body 12, there is space between the valve element 13 and valve pocket 121,
Core assembly 111 and push rod 112 control the up and down motion of valve element 13, and the valve element 13 is provided with four circumferential seals 131, this
Valve pocket 121 is separated into five sections by four circumferential seals 131, and every section of valve pocket side wall is provided with the runner 15 communicated with the external world,
And connected by inner flow passage 122 between the top runner and bottom runner, realize the circulation of medium；Set inside the valve element 13
There is cavity, and the side wall of valve element 13 is provided with through hole 132, for the flowing of medium between different runners；The periphery of the push rod 112
It is provided with sealing ring 112.
In above structure, sealing ring 112 can be effectively isolated valve pocket 121 and coil block 11, prevent medium from entering into line
In coil assembly 11, it is to avoid the damage of coil block 11.Meanwhile, circumferential seal 131 plays a part of to seal and separate valve pocket, uses
The switching of runner, realizes difference in functionality when work.
In the present invention, the upper valve core 133 and bottom spool 134 of the valve element 13 including molding assembly are easy to assembly, it is described on
