Referring to FIG. 6, present embodiments provide a kind of spool 10, it is slidably matched use for the valve body 20 with air filling gun,
There is sliding channel 200 in valve body 20, be equipped with the first sealing 210 and the second sealing 220, valve body 20 in sliding channel 200
On the import (not shown) that can be connected to gas source between the first sealing 210 and the second sealing 220.Spool
10 can slide relative to valve body 20 along first direction, and the air inlet 104 on spool 10 can be crossed on valve body 20 first close
Envelope portion 210, at this point, the import of air inlet 104 and valve body 20 blocks, it in this state can be with pressure release.Meanwhile spool 10 being capable of phase
Valve body 20 is slided in a second direction, and the air inlet 104 on spool 10 can cross the first sealing 210 on valve body 20
And between the first sealing 210 and the second sealing 220, so that the import of the air inlet 104 of spool 10 and valve body 20 connects
It is logical, at this point it is possible to be delivered to the gas of gas source by spool 10 and valve body 20 to aerating equipment.What the present embodiment was mentioned adds
Air gun can be used for the gases such as hydrogenation, natural gas, it is clear that can also add other kinds of gas, herein without arranging one by one
It lifts.Spool 10 provided in this embodiment relative to valve body 20 slide when, be not easy it is stuck in valve body 20, it is safe and reliable.
It should be noted that the first sealing 210 can be and be fixed on the sealing ring on 20 internal perisporium of valve body, for example,
Rubber ring.
Fig. 1 and Fig. 2 are please referred to, spool 10 provided in this embodiment includes the first core section 100 and second being fixedly connected
Core section 110, the first core section 100 are provided with first runner 103 and the air inlet being connected to first runner 103 104, air inlet
104 for the inlet communication with valve body 20；Second core section 110 be provided with the second flow channel 111 being connected to first runner 103 and
The gas outlet 112 being connected to second flow channel 111, gas outlet 112 with the exhaust outlet of valve body 20 for being connected to.It should be noted that
In order to improve the safety of air filling gun, pressure relief opening (not shown), gas outlet 112 while and valve body are provided on valve body 20
20 exhaust outlet is connected to pressure relief opening.
Spool 10 provided in this embodiment is operated including the first core section 100 and the second core section 110 being fixedly connected
The second core section 110 can be driven to move when the first core section 100 together, or first can be driven when operating the second core section 110
Core section 100 moves together.Assembling spool 10 and during valve body 20, the correspondence being directly inserted into spool 10 in valve body 20
Position.
And the valve core of traditional multisection type needs multiple valve core segments being successively fitted into valve body in assembly
In 20, and the valve core segment matched needs to guarantee cooperation precision, and assembly difficulty is high.In order to improve traditional valve core
Defect, spool 10 provided in this embodiment, since the first core section 100 is to be fixedly connected with the second core section 110, i.e., spool 10 is one
Body formula structure, spool 10 is once just inserted into valve body 20 when assembly, and needs when eliminating the assembly of conventional valves core
The step of adjusting the rigging position of multiple valve core segments, reduces assembly difficulty, saves assembly time, improves assembly effect
Rate.
Simultaneously as spool 10 is an integral structure, when operating spool 10 and being slided relative to valve body 20, spool 10 it is each
The movement of a position be it is synchronous, spool 10 can be directly realized by by the external force being applied on spool 10 relative to valve body 20
Reciprocatingly slide, and in the case where guaranteeing the enough situations of external force, spool 10 can be as external force be in a respective direction relative to valve
Body 20 does corresponding sliding action, and then completes air inlet 104 and the inlet communication of valve body 20 or the operation of blocking.Without
Occur after the external force that spool 10 can be driven to slide relative to valve body 20 is applied to spool 10, spool 10 is also stuck in valve body 20
It is inside unable to the case where doing corresponding sliding relative to valve body 20, the sliding of spool 10 is flexible, and high reliablity extends air filling gun
Service life, improve safety, reduce maintenance cost.And traditional multisection type valve core is during exercise, due to valve
Door core segment is independent component, when a valve core segment in multiple valve core segments moves, can not drive remaining valve
Door core segment moves together, and then remaining valve core segment is caused the stuck situation in valve body 20 easily occur, and reliability is low.
Referring to Fig. 2, optional in the present embodiment, the first core section 100 and the second core section 110 can be integrally formed, first
