The utility model discloses a kind of flange valve sealing test devices, including testing short tube, it tests among the both ends sealing of short tube and forms cavity, it is staggered on test short tube and is installed with air pump connector, pressure gauge connector and test connector, the air pump connector, pressure gauge connector and test connector are connected with cavity, and matching flange is equipped on test connector；The venthole with test connector coaxial arrangement is equipped on matching flange, ring convex platform is coaxially provided with around venthole, it is circumferential at least provided with two groups of mounting holes around ring convex platform, at least provided with two groups of annular seal grooves on ring convex platform；Connector diameter and the mounting hole arrangement mode for having flange valve are not exactly the same；By set three kinds of annular seal grooves, three kinds of mounting holes and between be dexterously used cooperatively, meet the sealing test of different size model flange valve in 9, the problem of avoiding the flange valve test of different size needs frequently to replace flange, improves equipment efficiency.
Description
Technical field
The utility model is related to valve seal test device technical fields more particularly to a kind of flange valve sealing test to fill
It puts.
Background technology
Flange valve through repairing needs to test being sealed property of valve when reusing asks in order to avoid there is leakage
It inscribes and causes the accident, yet with the model disunity of flange valve, be required for when measuring leak detection to flange valve every time
The connector to match is replaced in welding, inconvenient for operation, time-consuming and laborious.
The content of the invention
The utility model aim is that propose a kind of flange valve close to solve above-mentioned problems of the prior art
Test device is sealed, the utility model is adopted the technical scheme that in order to achieve the above objectives：
A kind of flange valve sealing test device, including testing short tube, the both ends for testing short tube seal intermediate formation cavity,
It is staggered on test short tube and is installed with air pump connector, pressure gauge connector and test connector, the air pump connection
Head, pressure gauge connector and test connector are connected with cavity, and matching flange is equipped on test connector；It is matching
Flange is equipped with the venthole with test connector coaxial arrangement, and ring convex platform is coaxially provided with around venthole, circumferential extremely around ring convex platform
Two groups of mounting holes are equipped with less, at least provided with two groups of annular seal grooves on ring convex platform.
Preferably, the group number of mounting hole is equal with the group number of annular seal groove, and one group of mounting hole and corresponding one group
Annular seal groove group is sealing unit, and the flange valve of different model is connected by corresponding sealing unit with test connector
It connects.
It is had the beneficial effect that possessed by the utility model：The connector diameter of existing flange valve and mounting hole arrangement mode
It is not exactly the same, the present apparatus by set general three kinds of basic annular seal grooves, three kinds of mounting holes and between dexterously
It is used cooperatively, meets the sealing test of different size model flange valve in 9, avoid the flange valve test of different size
The problem of needing frequently to replace flange, improves equipment efficiency.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the structure diagram of matching flange.
Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of flange valve sealing test device, including testing short tube 6, the both ends sealing of test short tube 6
Centre forms cavity, is staggered on test short tube 6 and is installed with air pump connector 5, pressure gauge connector 4 and test connector
3, the air pump connector 5, pressure gauge connector 4 and test connector 3 are connected with cavity, on test connector 3
Matching flange 1 is installed；The venthole 7 being coaxially disposed with test connector 3 is equipped on matching flange 1, it is coaxial around venthole 7
It is circumferential at least provided with two groups of mounting holes around ring convex platform 2 equipped with ring convex platform 2, at least provided with two groups of ring packings on ring convex platform 2
Slot, mounting hole includes first group of mounting hole, 10, second groups of mounting holes 8 and the 3rd group of mounting hole 9 in the present embodiment；Annular seal groove
Including first annular seal groove 11, the second annular seal groove 12 and the 3rd annular seal groove 13.
Wherein, the group number of mounting hole is equal with the group number of annular seal groove, and one group of mounting hole and corresponding one group of ring
Shape seal groove group is sealing unit, and the flange valve of different model is connected by corresponding sealing unit with test connector.
In the present embodiment, one is taken in first group of mounting hole, 10, second groups of mounting holes 8 and the 3rd group of mounting hole 9 three
A mounting hole takes an annular close in first annular seal groove 11, the second annular seal groove 12 and the 3rd annular seal groove 13
Sealing groove can form 3 × 3=9 sealing units, therefore can be sealed survey to the flange valve of nine kinds of different size models
Examination.
Limitation of the present embodiment not to works such as the shape of the utility model, material, structures in any form, every foundation
Any simple modification, equivalent change and modification that the technical essence of the utility model makees above example, belongs to this reality
With the protection domain of new technique scheme.
