Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, the present invention provides a kind of technical solution:A kind of pressure adjustment relief valve, including valve body 1, the second electromagnetism
Iron 2, pressure regulating cavity 3 and draining chamber 4, the valve body 1 is provided with oil outlet 5 and oil inlet 6, and 6 top of oil inlet is provided with spool chamber
7,7 top of the spool chamber is hinged with baffle 8, and 8 bottom of baffle is installed with valve core spring 9,9 periphery of the valve core spring
It is bolted and the first electromagnet 10 is installed, and 9 bottom of valve core spring is bonded with spool 11, second electromagnet 2 is logical
It crosses bolt and is fixedly mounted on 11 top of spool, and spool 11 is slidably connected with spool chamber 7, the spool chamber 7 is connected by oilhole 12
It is connected to oil pocket 13, the pressure regulating cavity 3 is arranged in 13 side of oil pocket, and 3 internal slide of pressure regulating cavity is connected with push plate 14, the push plate
14 sides are bonded with pressure spring 15, and 15 side of pressure spring is bonded with cone valve 16, and 6 side of the oil inlet is provided with drain tap
17, the draining chamber 4 is opened in 17 side of drain tap, and 4 bottom of draining chamber is connected by oilhole 12 with oil outlet 5, the draining
4 interior side of chamber is bonded with draining spring 18, and 18 side of draining spring is bonded with draining cone valve 19.
14 side of the push plate is welded with push rod 20, and push rod 20 is threadedly coupled with valve body 1, and 20 one end of the push rod is run through
Valve body 1 is connected with adjusting handle 21, facilitates the position for adjusting push plate 14,11 bottom of the spool is provided with oil transportation hole 22, facilitates oil
Into spool 11, first electromagnet, 10 and second electromagnet 2 is provided with coil, facilitates the first electromagnet 10 and second of control
