Description
Technical field
The utility model relates to a kind of water injection valves.
Background technique
Water injection valve is a kind of product more early applied on the domestic caving roof coal hydraulic support of coal mine, its working principle is that foundation
The switch control to the spraying firing dust time is carried out in the movement of bracket jack, has solved no problem at that time, has also been played certain
Effect.With a large amount of uses of caving roof coal hydraulic support, corresponding such water injection valve also exposes some ask in use
Topic, such as open slowly, water flow is small, close cannot be automatic, in time, tightly.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of resets more in time, the more strict water injection valve of sealing.
To solve the above problems, the technical solution adopted in the utility model includes: including valve body, is mounted in the valve body
Core assembly, it is characterised in that: the core assembly mainly by locking joint, spool, valve seat, mandril, open connector form,
The extension of the locking joint front end is equipped with valve core installation cavity, liquid outlet, and the spool is arranged in the valve core installation cavity
It is slidably matched with it and the taper valve of end and liquid outlet cooperates, reset spring is set between the spool and locking joint,
The mandril has pushing part, the first slide wall, the second slide wall, and the taper valve cooperation of the pushing part and the spool is described
The setting of first slide wall is slidably matched in valve seat with it, and the second slide wall setting is slidably matched in unlatching connector with it.
The water injection valve, it is characterised in that: the second slide wall of the mandril is equipped with retaining ring, sealing ring.
The water injection valve, it is characterised in that: the locking joint, valve seat junction be equipped with gasket.
The water injection valve, it is characterised in that: retaining ring, sealing ring are equipped between the locking joint, spool.
The water injection valve advantage of the utility model is as follows: 1, it by locking joint in conventional water jet valve and merges into a single whole part,
It opens connector to be integrated with guide sleeve, this merges at two and reduces two seals and reduce leakage condition, and then makes to seal tighter
It is close；2, traditional reset spring is limited by spool installation space, and thrust is smaller, cause valve core reset not in time, it is closed not tight
Close, the utility model is outer diameter dynamic sealing by cancelling spool outer diameter to cover sealing ring, has conceded dress diameter reset springs a little greatly
Its thrust is improved by big spring in space, so make valve core reset more in time, sealing it is tighter；3, the top in conventional water jet valve
Bar positioning and guiding is short, easily leads to movement and does not block, influences the breakdown action and amount of opening of spool, the utility model is by improving mandril
Location structure and guiding length, keep its movement more smooth.
The utility model is described further with reference to the accompanying drawings of the specification.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model water injection valve；
Fig. 2 is the cross-sectional view of the utility model core assembly figure；
Fig. 3 is the cross-sectional view of the utility model mandril figure.
Specific embodiment
- 3 show referring to Fig.1, the water injection valve of the utility model, including valve body 1, the core assembly being mounted in the valve body 1
a.The core assembly a is mainly made of locking joint 2, spool 3, valve seat 4, mandril 5, unlatching connector 6, the locking joint 2
The extension 7 of front end is equipped with valve core installation cavity 8, liquid outlet 9, and the spool 3 is arranged in the valve core installation cavity 8, and and its
It is slidably matched, and the taper valve 10 of 3 end of the spool and the switch of liquid outlet 9 cooperate.The spool 3 and locking joint 2 it
Between reset spring 11 is set, the mandril 5 has pushing part 12, the first slide wall 13, the second slide wall 14, the pushing part 12 and institute
The taper valve 10 for stating spool 3 cooperates, the back-and-forth motion for control valve core 3.First slide wall 13 be arranged in valve seat 4 with
It is slidably matched, and the setting of the second slide wall 14 is slidably matched in unlatching connector 6 with it.
Further, the second slide wall 14 of the mandril 5 is equipped with retaining ring 15, sealing ring 16.The locking joint 2, valve
The junction of seat 4 is equipped with gasket 17.Retaining ring 15, sealing ring 16 are equipped between the locking joint 2, spool 3.The valve seat 4
Both ends are equipped with sealing ring, so that water injection valve integrally realizes sealing effect.
It is upper described, limitation in any form not is done to the utility model, although the utility model is preferably to implement
Case discloses as above, however is not intended to limit the utility model, any person skilled in the art, is not departing from this reality
With in new technique aspects, when the structure and technology contents using the disclosure above make a little change or are modified to
The equivalence enforcement case of same variation, but all contents without departing from technical solutions of the utility model, according to the utility model
Technical spirit still belongs to the utility model technology to any simple modification, equivalent change and modification made by the above case study on implementation
Aspects.
