In the optional scheme of the present embodiment, further, the second seal assembly 28 includes the second sealing ring and gasket, and
Gasket is located at below the second sealing ring.Specifically, the second seal assembly 28 includes the second sealing ring and copper backing, and the second sealing
Part can carry out the motion seal between valve rod 21 and pressure cap.
In the optional scheme of the present embodiment, further, 21 bottom of valve rod is connected with flap 29, flap through apopore
29 are driven keying apopore by valve rod 21.21 bottom of valve rod is through apopore and is equipped with the skeleton 291 being fixedly connected, the skeleton
Flap 29 is coated with by skill in the vulcanization of rubber on 291, flap 29 and the apopore work sealing of 20 bottom of spool are equipped, can be in valve
Apopore is closed when unlatching apopore or valve rod 21 move up when bar 21 moves down, while also in the upper and lower of flap 29
Expanding ring 26 is respectively equipped with, which is also secured on valve rod 21, available for increase flap 29 in seal process
Rigidity, and ensure sealing reliability.
Be equipped with the first seal assembly 25 such as the first sealing ring between valve rod 21 and spool 20,22 top of upper spring seat be equipped with
21 fixed expanding ring 26 of valve rod and stopped, then 23 upper end pushing tow of spring is on upper spring seat 22；The lower spring cup
24 are arranged on above the first sealing ring, and lower spring cup 24 is sealed by extrusion process in press-in spool 20, then will be under spring 23
End pushing tow ensure that 24 fixed reliability of lower spring cup on lower spring cup 24, and 23 elastic force of spring just can be always on pushing tow at this time
Simultaneously driving stem 21 possesses a driving force moved up to spring base 22.When pressure medium flows into the inlet opening of spool 20,
Pass through the sealing between the first sealing ring and valve rod 21, you can effectively by dielectric impedance outside the first sealing ring.
The hard sealing of extruding assembling between the lower spring cup 24 of the utility model and spool 20 is provided in the first sealing ring
Top, that is to say, that for the hard Seal Design of lower spring cup 24 and spool 20 after the sealing of the first sealing ring, this causes this
The seal point of place's structure is reduced at one, that is, is reduced the generation of leakage point, while flowed medium after structural adjustment, is increased
Area of passage in road so that refrigeration or heating effect are more preferably.
The electric two-way valve that the embodiment of the utility model provides includes drive component 1 and valve member 2, wherein valve group
Part 2 is the structure that a kind of intake tunnel 3 and exhalant canal 4 are led directly in level, and intake tunnel 3 is connected with the inlet opening of spool 20,
