Description
Technical field
Valve detection field is the utility model is related to, refers in particular to a kind of safety valve of oil tank test connection valve.
Background technology
Safety valve of oil tank is part essential in automotive oil tank component, and when slide-out, safety valve can prevent from firing
Oil overflows from safety valve, and then continuous oil supply under normal circumstances；And existing safety valve is in measurement performance, its valve nozzle and safety
The test mouth of valve test machine realizes sealing essentially by the artificial rubber ring that compresses, and not only operating efficiency is low, labor intensity is big and close
Envelope effect can not ensure, easily influence measuring accuracy.
Utility model content
The purpose of the utility model is to provide a kind of safety valve of oil tank test connection valve for overcome the deficiencies in the prior art,
Quickly the test mouth of the valve nozzle of safety valve and test machine can be tightly connected, be produced into so as to improve operating efficiency, save
This, and ensure that measuring accuracy.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of safety valve of oil tank tests connection valve, bag
Containing be internally provided with the valve body of cavity volume, the valve head for being arranged on valve body one end, surface is provided with convex shoulder and middle part is provided with valve opening
Valve element；Rubber ring is provided with the valve head, valve element is slidably disposed in valve body, and one end is bonded with rubber ring；It is described
The convex shoulder of spool face is arranged in the cavity volume of valve body, and the valve pocket of closing is formed with valve body；The other end of the valve body is set
There is the air inlet connected with valve pocket.
Preferably, it is provided with sealing ring between the inner surface of the convex shoulder of the spool face and valve body cavity volume.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
Safety valve of oil tank test connection valve described in the utility model extrudes rubber ring by valve element, makes rubber ring radial direction side
To expansion, quickly the test mouth of the valve nozzle of safety valve and test machine can be tightly connected, so as to improve operating efficiency, save
Production cost, and ensure that measuring accuracy.
Brief description of the drawings
Technical solutions of the utility model are described further below in conjunction with the accompanying drawings：
Accompanying drawing 1 is the structural representation that safety valve of oil tank described in the utility model tests connection valve；
Accompanying drawing 2 is the operating diagram that safety valve of oil tank described in the utility model tests connection valve.
Wherein：1st, valve body；11st, cavity volume；2nd, valve head；3rd, valve element；31st, convex shoulder；32nd, valve opening；4th, rubber ring；5th, sealing ring；
6th, air inlet；7th, valve pocket.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
Accompanying drawing 1-2 is that safety valve of oil tank described in the utility model tests connection valve, comprising being internally provided with cavity volume 11
Valve body 1, the valve head 2 for being arranged on the one end of valve body 1, surface is provided with convex shoulder 31 and middle part is provided with the valve element 3 of valve opening 32；The valve
Rubber ring 4 is provided with first 2, valve element 3 is slidably disposed in valve body 1, and one end is bonded with rubber ring 4；The table of valve element 3
The convex shoulder 31 in face is arranged in the cavity volume 11 of valve body 1, and the valve pocket 7 of closing is formed with valve body 1；The other end of the valve body 1 is set
The air inlet 6 connected with valve pocket 7 is equipped with, for promoting valve element 3 to extrude rubber ring 4, expands the radial direction of rubber ring 4, realizes
Fast sealing connects；Sealing ring is provided between the convex shoulder 31 on the surface of valve element 3 and the inner surface of the cavity volume of valve body 1, prevents valve
Gas in chamber 7 enters valve opening 32, influences measuring accuracy.
During use：First the valve nozzle of safety valve is stretched into rubber ring 4, then inflated by air inlet 6 to valve pocket 7, promotes valve
Core 3 extrudes rubber ring 4, expands the radial direction of rubber ring 4, quickly seals the test mouth of the valve nozzle of safety valve and test machine and connects
Connect；Conversely, stopping inflating to valve pocket 7, valve element 3 automatically resets under the elastic force of rubber ring 4, makes the valve nozzle and test machine of safety valve
Test mouth separation.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
Safety valve of oil tank test connection valve described in the utility model extrudes rubber ring by valve element, makes rubber ring radial direction side
To expansion, quickly the test mouth of the valve nozzle of safety valve and test machine can be tightly connected, so as to improve operating efficiency, save
Production cost, and ensure that measuring accuracy.
It the above is only concrete application example of the present utility model, do not form any limit to the scope of protection of the utility model
System.All technical schemes formed using equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it
It is interior.
