It is protruded under the action of power to the taper hole end of valve opening 411, a part of the conical end of spool 42 protrudes into outside valve opening 411, remaining part
The circular conical surface divided is contacted with the taper hole inner wall of valve opening 411, forms sealing, ensure that the self-sealing of pressure valve 4, and in press valve
When the circular cone tip of core 42, moving in spool 42 separates circular conical surface with the taper hole inner wall of valve opening 411, that is, is able to achieve ventilation.
Pressure measuring tie-in 6 and above-mentioned pressure valve 4, which match, to be used comprising: attachment base 61, sealing ring 62 and top 63, even
On joint chair 61 perforation be provided with stepped hole 611, the small bore end of stepped hole 611 is connect with manograph 5, the macropore of stepped hole 611 and
The outer diameter of valve seat 41 is adapted to and is detachably connected with valve seat 41, specifically can be in 611 macropore inner wall internal screw thread 614 of stepped hole, valve seat
The external screw thread 412 being adapted to internal screw thread 614 is arranged in 41 outer surface, so that it is threadedly coupled attachment base 61 and valve seat 41, dismounting
It is convenient.Sealing ring 62 is arranged in the macropore of stepped hole 611 and is resisted against on step surface, referring to Fig. 7, when connection, valve seat 41
End is resisted against sealing ring 62, guarantees the sealed connection of valve opening 411 and stepped hole 611.Top 63 is arranged in stepped hole 611 simultaneously
Along the axially extending of stepped hole 611, come directly towards 63 one end and be connected on the hole wall of close aperture end of stepped hole 611, come directly towards
There is gap between 63 circumferential direction and stepped hole 611, guarantees to survey passing through for body of calming the anger, the other end for coming directly towards 63 protrudes from stepped hole
611 step surface, to come directly towards the conical tip that 63 end can protrude spool 42 when attachment base 61 and valve seat 41 dock
It is pressed, pressure valve 4 is made to ventilate, guarantee the normal survey pressure of manograph 5.
Meanwhile to avoid in 41 connection procedure of attachment base 61 and valve seat, there is the also malcompression sealing of sealing ring 62, top
63, which just open spool 42, is ventilated and causes gas leakage, is caused to survey to press and is not allowed, and the present embodiment is that pressure measuring tie-in 6 is provided with pushing mechanism
64。
Referring to Fig. 6 and Fig. 7, top-pushing mechanism 64 is arranged in the aperture of stepped hole 611 comprising: guide plate 641, guiding
Seat 642, elastic sealing film 643, voussoir 644 and compression bar 645.Guide plate 641 and guide holder 642 are separately fixed at leaning in aperture
One end of nearly macropore and one end far from macropore are respectively arranged with the axis along stepped hole 611 on guide plate 641 and guide holder 642
To the first shaft hole 6411 and the second axis hole 6421 of perforation, the aperture of the second axis hole 6421 is greater than first shaft hole 6411, guide holder
The slide opening 6422 radially penetrated through along stepped hole 611 is provided on 642；The position corresponding with 6422 one end of slide opening of attachment base 61
Offer connecting hole 612, one end setting fluted 613 of connecting hole 612 being located in stepped hole 611, and the opening of groove 613
Area is greater than connecting hole 612；Elastic sealing film 643 is sealingly disposed in the opening of groove 613, thus by connecting hole 612 and platform
Rank hole 611 seals off, and avoids from 612 gas leakage of connecting hole, and the area of elastic sealing film 643 is greater than connecting hole 612, can give
Elastic sealing film 643 provides enough deformation spaces and deflection.Voussoir 644 is slidably inserted on slide opening 6422, voussoir
644 one end being located in the second axis hole 6421 has the inclined-plane towards guide plate 641, and voussoir 644 is located at outside guide holder 642
One end be fixedly connected with elastic sealing film 643；Compression bar 645 is slidably inserted into connecting hole 612, the inner end of compression bar 645
It is fixedly connected with elastic sealing film 643, the outer end of compression bar 645 protrudes from the outer surface of attachment base 61.Pass through elastic sealing film 643
The elasticity having, can make elastic sealing film 643 keep plane device under normal conditions, and voussoir 644 and compression bar 645 are in such as Fig. 6
Shown in home position；If applying inward pressure to compression bar 645, elastic sealing film 643 can be pressed and be deformed inward and drive
It is moved in voussoir 644, after revocation is to the pressure of compression bar 645, the rebound of elastic sealing film 643 resets voussoir 644 and compression bar 645.
Top 63 is set Step Shaft by the structure of top-pushing mechanism 64 in correspondence, and the small shaft part of Step Shaft is slidably inserted
In the first shaft hole 6411 on guide plate 641, the big shaft part of Step Shaft is slidably inserted into second on guide holder 642
In axis hole 6421, and the end of big shaft part is abutted with the inclined-plane of voussoir 644, and the top 63 after connecting under normality does not connect with spool 42
Touching, and when being moved in voussoir 644, can the end to the big shaft part of top 63 form wedging effect, push top 63 to spool 42
It is mobile to form press, and then make the ventilation conducting of pressure valve 4.The big shaft part end of top 63 is preferably also provided with towards voussoir 644
Inclined-plane improves the wedging effect between voussoir 644 and top 63, improves smoothness when ejection top 63.
