Specific embodiment
The utility model is described further referring to attached drawing.
As shown, a kind of hydraulic pressure switch of solenoid valve, including mounting base 1, microswitch 2, cover board 3.The one of shell 11
End offers conducting orifice 41, is injected into shell 11 to water；The other end offers accommodating chamber 42.
A circular support base 43 is fixed on conducting orifice 41.Connector sleeve is slidably connected in support base 43,
There are multiple support plates 44 close to the side integrated setting of shell 11 in connector sleeve.Between being formed between two neighboring support plate 44
Gap makes each support plate 44 can deformation occurs.It is fixed with connection ring 45 on the inner wall of support plate 44, is fixed on outer wall
Connection bump 46.Make connection bump 46 for contradicting with support base 43 towards the side of shell 11.Support plate 44 is convex far from connecting
The one end for playing 46 is located at the outside of shell 11, and fixes restraining position ring block 47.It is used for stop collar 47 with support base 43 far from shell
11 side contradicts.To make support plate 44 be not easy to deviate from from support base 43.
It is placed between shell 11 and support plate 44 using sealing ring 48 made of rubber, to promote shell 11 and branch
Support the leakproofness between seat 43.
Placing groove in a ring is offered in accommodating chamber 42, is placed in placing groove using soft close made of rubber
Closing disk 5.The side integrated setting of soft seal disc 5 back to sealing ring 48 has conflict protrusion, in order to contradicting with reed.It is soft
Property seal disc 5 section in M shape be arranged.Seal receptacle 51 is placed in accommodating chamber 42, seal receptacle 51 and soft seal disc 5 are carried on the back
The side of support base 43 is contradicted, realizes the positioning to soft seal disc 5.Reed is placed on seal receptacle 51.By positioning seat
12 are placed in accommodating chamber 42, and are pressed on reed, and the positioning of reed is realized by seal receptacle 51 and positioning seat 12.The present embodiment
In, reed is made of copper.
Placement rack 6 is placed in accommodating chamber 42, is placed in positioning seat 12.Microswitch 2 includes 21 He of the first binding post
Second binding post 22.First binding post 21, the second binding post 22 are worn and are fixed on placement rack 6.By 23 one end of elastic piece
It is fixed on the first binding post 21, the other end is used to contradict with the second binding post 22.In the case where not by external force, elastic piece 23
It keeps contradicting with the second binding post 22.In the present embodiment, elastic piece 23 is made of copper.
The setting cylindrical of push rod 61, is slidably connected on positioning seat 12 and between reed and elastic piece 23, will push away
