Description
Technical field
The utility model relates to circuit line fields, and in particular to flange plate is used in a kind of verification of valve.
Background technique
Valve is the control unit in fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents adverse current, pressure stabilizing, shunting
Or the functions such as overflow pressure relief.Valve verification needs to carry out temporary sealing to valve using flange plate, and is carried out by pre-manufactured hole
Inlet and outlet process, in checking procedure, although original flange plate is able to satisfy use, but because value pressure test pressure is higher, Yuan Youfa
Blue cover board easily causes silk plug to fall off under extreme conditions, and to verification, personnel are damaged.
Original gas outlet of flange plate is M22mm*1.5mm pipe screw thread, is sealed using Rubber washer, and sealing effect is poor,
Rubber washer service life is short；Original air inlet is 15mm pipe screw thread, is sealed using raw material band, and it is tight that rear thread abrasion is used for multiple times
Weight has " slide fastener " phenomenon, while raw material band seals not applicable hyperbaric environment, easily reveals.
Utility model content
The purpose of this utility model is to provide a kind of valve verification flange plates, use to solve existing valve verification
The problem that flange plate service life is shorter, safety in utilization is poor.
To achieve the above object, the technical solution of the utility model is a kind of valve verification flange plate, including flange
Ontology and Threaded Connector Coupling, the flange body are coaxially bonded and are provided with two panels, and flange body axle center offers perforative threaded hole, and two
Piece flange body threaded hole aperture is identical, and the Threaded Connector Coupling includes choking portion and threaded joints, and the Threaded Connector Coupling is opened along axis
Equipped with air inlet, threaded joints are provided with the pipe screw thread with threaded hole cooperation, and the Threaded Connector Coupling is connected through a screw thread portion and method
Blue ontology is threadedly coupled.
As advanced optimizing, the choking portion offers seal groove close to threaded joints one end, in the seal groove
It is equipped with gasket.
As advanced optimizing, the gasket is metal material.
As advanced optimizing, the gasket is copper gasket.
As advanced optimizing, the sealing mat thickness is big compared with the depth of the seal groove.
As advanced optimizing, the seal groove diameter is 16mm, and seal groove depth is 1mm, and the gasket diameter is
16mm, gasket is with a thickness of 5mm.
As advanced optimizing, the threaded hole is set as M20mm*1.5mm.
As advanced optimizing, the choking portion offers the connecting hole perpendicular to Threaded Connector Coupling axis.
The utility model has the advantages that
1, unified screw thread specification is set by two panels flange body, and the Threaded Connector Coupling for making unified model can effectively be kept away
Exempt from the problem of sealing serious bring thread abrasion, not applicable hyperbaric environment and easy leakage using raw material band, there is sealing effect
Well, long service life and the advantages of be easily installed and facilitate production.
2, good sealing effect can be played by opening up seal groove in choking portion and being sealed processing by gasket,
And use metal material production gasket that can make sealing effect more preferably, the service life is longer.

Specific embodiment
The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.
A kind of valve verification flange plate, includes flange body 1 and Threaded Connector Coupling 2, flange body 1 combined with Figure 1 and Figure 2,
Be fixed on by silk plug at the air inlet of valve 3, flange body 1 be it is discoid, flange body 1 close to marginal position axially be arranged
There are multiple fixation holes 11, be provided with screw thread in fixation hole 11, for fixed with valve 3.Coaxially fitting is provided with two to flange body 1
Piece, 1 axle center of flange body offer perforative threaded hole 12, and 1 threaded hole of two panels flange body, 12 apertures are identical, and Threaded Connector Coupling 2 is logical
The threaded hole 12 is crossed to be fixedly connected with flange body 1.
Threaded Connector Coupling 2 includes choking portion 21 and threaded joints 22, and choking portion 21 and threaded joints 22 are integrally formed, and is
Cylinder, and axis is overlapped, 21 diameter of choking portion is big compared with 22 diameter of threaded joints.Threaded Connector Coupling 2 offers air inlet along axis
24, threaded joints 22 are provided with the pipe screw thread cooperated with threaded hole 12, and Threaded Connector Coupling 2 is connected through a screw thread portion 22 and flange body
1 is threadedly coupled.
Choking portion 21 offers seal groove 211 close to 22 one end of threaded joints combined with Figure 1 and Figure 2, the seal groove 211
For annular groove, axis and choking portion 21 are coaxial, and gasket 23 is equipped in seal groove 211, by seal groove 211 with it is close
The cooperation of packing 23 can play good sealing effect, and gasket 23 is metal material, it is preferred that sets copper for gasket 23
Gasket 23 makes it have better seal performance, and service life is longer, depth of 23 thickness of gasket compared with seal groove 211
Greatly, gasket 23 is connect closer with flange body 1 when the installation of Threaded Connector Coupling 2 can be made fixed, and sealing effect is more preferable, and choking portion 21 is opened
Equipped with the connecting hole 212 perpendicular to 2 axis of Threaded Connector Coupling, can be connected convenient for Threaded Connector Coupling 2 with air inlet pipe by the connecting hole 212
It connects, so that convenient carry out air-leakage test to valve 3.
A kind of preferred embodiment presented below: threaded hole 12 is set as M20mm*1.5mm, and 211 diameter of seal groove is 16mm, close
