The head of described spool is the frustum structure.
In the fuel feed hole of described joint, be provided with vertically and promote the short push rod that described push rod backs down described spool.
The utility model adopts technique scheme, and compared with prior art, it is simple in structure that water injection valve is driven in this pair control, is easy for installation and maintenance, and namely installs simply, easy to maintenance, and that can guarantee to produce normally carries out.
Description of drawings
Fig. 1 opens the sectional view of water injection valve for two controls of the present utility model;
Mark among the above-mentioned figure is: 1, valve body; 2, joint; 3, spool; 4, valve seat; 5, valve pocket; 6, push rod; 7, first interface; 8, second interface; 9, return spring; 10, lack push rod.
The specific embodiment
Be illustrated in figure 1 as two controls that a kind of coal supply of the present utility model ore deposit comprehensive mining hydraulic bracket uses and drive water injection valve, comprise valve body 1, insert the valve pocket 5 of the joint 2 that is connected with valve body 1 in the valve body 1 and the valve pocket that is arranged in valve body 1, spool 3, valve seat 4, push rod 6, valve body 1 is provided with water inlet, delivery port and first interface 7 that is connected with reversal valve, first interface 7 leads to the liquid storage cylinder between valve pocket 5 and joint 2 of valve body 1, be provided with second interface 8 that is connected with column epicoele or plate jack epicoele at joint 2, joint 2 inserts in the valve body 1 and is threaded with valve body 1, on this joint 2, also be provided with the fuel feed hole that is communicated with the valve pocket of valve body 1, push rod 6 is between spool 3 and joint 2, valve pocket 5 is enclosed within the outside of push rod 6, valve seat 4 and between valve pocket 5 and spool 3, the head of spool 3 and valve seat 4 are tightly connected, on spool 3, also be connected with return spring 9, one end of return spring 9 is against on the end inwall of valve pocket of valve body 1, and the other end is against on the spool 3.
In addition, as shown in Figure 1, in the fuel feed hole of joint 2, be provided with vertically and promote the short push rod 10 that push rod 6 backs down spool 3, between the inwall of the fuel feed hole of lacking push rod 10 and joint 2, be provided with the O RunddichtringO.
For soft seal is connected, spool 3 adopts metal materials to make between the spool 3 that water injection valve is driven in this pair of control and the valve seat 4, and valve seat 4 adopts acetal plastics to make good seal performance.And as shown in Figure 1, the head of spool 3 is the frustum structure, the parts good seal performance, and also the structure of spool 3 is simpler.
As shown in Figure 1, between joint 2, valve seat 4, valve pocket 5 and valve body 1, also be provided with the O RunddichtringO, between push rod 6 and valve pocket 5, be provided with the O RunddichtringO.
Valve body 1 length of this pair of control water injection valve is 92mm, and width is 88mm, and thickness is 33mm.
The operating principle of this pair of control water injection valve: when having pressure fluid to be entered by second interface 8 on the joint 2 in the spraying system, hydraulic oil promotes short push rod 10 and moves, short push rod 10 promotes push rod 6 and moves towards spool 3 directions, promoting spool 3 is separated with valve seat 4, water inlet and delivery port are communicated with, and realize spraying; When another kind of situation needs auto spraying, have pressure fluid to enter first interface 7, liquid entered joint 2 inner chambers and promoted push rod 6 and move towards spool 3 directions this moment, promoted spool 3 and separated with valve seat 4, and water inlet is connected with delivery port, realizes spraying.
By reference to the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
