Description
Technical field
The utility model relates to automatic pressure relief valve fields, and in particular to a kind of releasing pressure automatically valve core.
Background technique
In automatic pressure relief valve in the right relatively broad application in spraying machine field, but under prolonged use, spool holds
It is easy to wear, cause sealing effect to be deteriorated, so that the power for needing to increase spraying machine in normal work could work normally, therefore
Cause the waste of the energy.
Utility model content
In view of the deficienciess of the prior art, the automatic leakage good the purpose of this utility model is to provide a kind of sealing effect
Pressure valve spool.
To achieve the above object, the utility model provides following technical solution: including insert body, setting in insert body
There are the intake antrum and pressure-releasing chamber being connected, is additionally provided with several water inlets on insert body, water inlet is connected with intake antrum；
Be additionally provided with sealing needle in pressure-releasing chamber, sealing needle is equipped with sealing ring and sealing block, sealing block and sealing ring it
Between be equipped with reservoir, be additionally provided with diversion trench on sealing needle, sealing block and intake antrum are adapted.
Further, be additionally provided with spring and push rod plug in pressure-releasing chamber, spring one end and sealing needle contradict connection, the other end and
Push rod plug contradicts connection, and push rod is equipped with the fixed block for fixed spring beyond the Great Wall, offers apopore on fixed block.
Further, sealing needle is equipped with limited block, is additionally provided with stop collar on limited block.
Further, push rod is additionally provided with plenum beyond the Great Wall, is equipped with through-hole in plenum, and through-hole penetrates through push rod plug, in plenum
Several pressurized holes are additionally provided with, pressurized hole is connected with through-hole.
The deficiencies in the prior art are compared, technical solution provided by the utility model is brought the utility model has the advantages that therefore making
Used time, the second sealing block protrude into intake antrum,, can when hydraulic pressure reaches to a certain degree since the second sealing block is in coniform
It is effective to carry out pressure release, while sealing ring and pressure-releasing chamber cavity wall are in contact, therefore sealing effect is more preferable, simultaneously because reservoir
In the presence of so that wearing even if sealing block generates in prolonged work, the liquid of partial penetration will be flowed in reservoir,
Since sealing ring and pressure-releasing chamber cavity wall are in contact, avoid and need to increase output work caused by the continual leakage of liquid
Rate just can guarantee the generation of the problem of normal work, save the energy, and the presence of diversion trench makes in pressure release, and liquid is along water conservancy diversion
The runner that slot and pressure release cavity wall are formed enters pressure-releasing chamber, avoid liquid be directly entered pressure-releasing chamber impact caused to other component and
The problem of accelerating other component to damage, extends the service life of spool.
Detailed description of the invention
Fig. 1 is the configuration schematic diagram of the utility model.
Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be merely to illustrate and explain the present invention, is not used to limit the utility model.
The utility model is described further referring to Fig.1.
A kind of releasing pressure automatically valve core, including insert body 1, insert body 1 is interior to be equipped with the intake antrum being connected and pressure release
Chamber is additionally provided with several water inlets 11 on insert body 1, and water inlet 11 is connected with intake antrum；
Sealing needle 2 is additionally provided in pressure-releasing chamber, sealing needle 2 is equipped with sealing ring 21 and sealing block, sealing block and sealing
It is equipped with reservoir 24 between ring 21, is additionally provided with diversion trench 22 on sealing needle 2, sealing block 21 and intake antrum are adapted；Sealing block
Including the first cylindrical sealing block 251 and in the second coniform sealing block 252, therefore when in use, the second sealing block
252 protrude into intake antrum, since the second sealing block 252 is in coniform, when hydraulic pressure reaches to a certain degree, can be carried out effectively
Pressure release, while sealing ring 21 and pressure-releasing chamber cavity wall are in contact, therefore sealing effect is more preferable, simultaneously because the presence of reservoir 24 makes
Even if obtaining sealing block generates abrasion in prolonged work, the liquid of partial penetration will be flowed in reservoir 24, due to
Sealing ring 21 and pressure-releasing chamber cavity wall are in contact, therefore avoid and need to increase output power caused by the continual leakage of liquid
The energy has been saved in the problem of just can guarantee normal work generation, and the presence of diversion trench 22 makes in pressure release, and liquid is along water conservancy diversion
The runner that slot 22 and pressure release cavity wall are formed enters pressure-releasing chamber, avoids liquid and is directly entered pressure-releasing chamber and causes to impact to other component
And the problem of accelerating other component to damage, extend the service life of spool.
Further, spring 3 and push rod plug 4 are additionally provided in pressure-releasing chamber, 3 one end of spring and sealing needle 2 contradict connection, another
End and push rod plug 4 contradict connection, and push rod plug 4 is equipped with the fixed block 41 for fixed spring 3, offers water outlet on fixed block 41
Hole 43, spring 3 is tower-shaped spring, therefore can effectively save the space in pressure-releasing chamber, so that pressure-releasing chamber is within the unit time
Can by the liquid of greater flow, meanwhile, the presence of fixed block 41 enables spring 3 effectively to be fixed, so that multiple
In the case where working in reciprocating mode, spring 3 will not be subjected to displacement, so that spool is more stable in working condition.
Further, sealing needle 2 is equipped with limited block 23, is additionally provided with stop collar 231 on limited block 23, therefore in spring 3
Combined with sealing needle 2 even closer, while the presence of stop collar 231 is but also spring 3 will not under prolonged use
Left and right offset, avoid causes the sealing needle 2 in pressure release to be easier to deviate to a direction because spring 3 or so deviates,
To aggravate the problem of sealing needle 2 is worn.
Further, it is additionally provided with plenum 42 on push rod plug 4, through-hole 422 is equipped in plenum 42, through-hole 422 penetrates through push rod
Plug 4 is additionally provided with several pressurized holes 421 in plenum 42, and pressurized hole 421 is connected with through-hole 422, when being full of liquid in pressure-releasing chamber
When body, a part of water flow is discharged from apopore 43, and a part is discharged from through-hole 422, while a part of water flow is from pressurized hole 421
Through-hole 422 is flowed into, is then discharged from through-hole 422, due to the hole link of pressurized hole 421 and through-hole 422, from pressurized hole
421 water flows for entering through-hole 422 increase water flow in through-hole, therefore improve the flow velocity of the water flow passed through in through-hole 422,
So that water flow discharge is more quick, therefore pressure release is more quick.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, the skill of this field
Art personnel carry out common variations and alternatives within the scope of technical solutions of the utility model should be included in the guarantor of the utility model
It protects in range.
