Description
Technical field
The utility model relates to subway, in particular to a kind of combined pressure for subway work water system valve is tested
Device.
Background technique
The High Speed Construction phase of all parts of the country subway market access at present, there are a large amount of water-system pipelines in station and ventilating shaft
Valve installing engineering, for the quality of strict control valve, relevant specification of country and standard do valve entry test and test
Specific regulation: playing the closed circuit valve of cutting action for being mounted on main pipe, should carry out intensity and tightness examination one by one
It tests；For the valve used on other pressure conduits, compressive resistance test and leak test, pass the test should be also done before installation
Rear can be used.The water system valve quantity of metro station construction is more, and specifications and models are more, carries out pressure testing after marching into the arena one by one
There are various problems, such as: it need to be spent a large amount of artificial for all models production valves test tool or matched flange mask
And material, and need to keep pressure constant within the defined duration, it wastes time.For problem as above, a kind of use is set
In the combined pressure experimental rig of subway work water system valve, checkability can be promoted, is economized on resources, control valve matter
Amount.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of combined types for subway work water system valve
Pressure experimental device promotes checkability with the process of the existing processing experiment equipment in the scene of reducing, and saves time cost, and advantageous
In ensuring valve mass.
It is as follows that the utility model solves technical solution used by its technical problem:
A kind of combined pressure experimental rig for subway work water system valve of the utility model, it is characterized in that:
Its main body is a tubular pressure vessel, and exhaust valve and the pressure gauge for detecting its cavity pressure is arranged on tubular pressure vessel,
Its longitudinal one end is by flange closure, other end setting pressurization interface arrangement；Longitudinally spaced setting on the tubular pressure vessel
The transfer tube of different bores, the external port setting flange arrangement of each transfer tube and is removably mounted to sealing mask thereon.
It further include silk mouth transfer tube, the upper end of silk mouth transfer tube has silk mouth connection structure, and lower end then passes through flange arrangement
It is connect with transfer tube.
The utility model has the beneficial effects that the valve that can need to make a strength test with leak test by same batch
It is mounted on tubular pressure vessel according to the connector of corresponding specification, interim water source is introduced into tubular pressure vessel and passes through exhaust
Valve drains device inner air, and tubular pressure vessel is pressurized to test pressure, can be to simultaneously to the progress of same batch valve
Compressive resistance test and leak test, greatly reduce the process of the existing processing experiment equipment in scene, promote checkability, when saving
Between cost, and it is advantageously ensured that valve mass.
Detailed description of the invention
This specification includes such as next width attached drawing:
Fig. 1 is a kind of signal of the combined pressure experimental rig for subway work water system valve of the utility model
Figure.
Component and corresponding label: tubular pressure vessel 10, pressurization interface arrangement 11, exhaust valve 13, flange are shown in figure
14, pressure gauge 15, transfer tube 20, sealing mask 21, silk mouth transfer tube 22.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to Fig.1, a kind of combined pressure experimental rig for subway work water system valve of the utility model,
Main body is a tubular pressure vessel 10, and exhaust valve 13 and the pressure for detecting its cavity pressure is arranged on tubular pressure vessel 10
Table 15, longitudinal one end are closed by flange 14, other end setting pressurization interface arrangement 11.Along vertical on the tubular pressure vessel 10
The transfer tube 20 of different bores is set to interval, and the external port of each transfer tube 20 is arranged flange arrangement and is removably mounted to thereon
Sealing mask 21.
For the valve for adapting to distinct interface, it is also configured with silk mouth transfer tube 22, the upper end of silk mouth transfer tube 22 has silk mouth
Connection structure, lower end then pass through flange arrangement and connect with transfer tube 20.It, can be by silk mouth transfer tube after rolling over except sealing mask 21
22 are fixedly mounted on transfer tube 20.
Referring to Fig.1, same batch is needed into the connecing according to corresponding specification with the valve of leak test that make a strength test
Head is mounted on transfer tube 20 or silk mouth transfer tube 22, and interim water source is introduced into tubular pressure vessel 10, passes through exhaust valve 13
10 inner air of tubular pressure vessel is drained, after exhaust valve 13 flows out clear water, closes exhaust valve 13, and start to tubulose pressure
Force container 10 is pressurized to test pressure, can carry out compressive resistance test and leak test to while to same batch valve,
The process for greatly reducing the existing processing experiment equipment in scene, promotes checkability, saves time cost, and it is advantageously ensured that valve matter
Amount.
The above is a kind of Combined press for subway work water system valve of the utility model that explains through diagrams
Some principles of power experimental rig are not intended to shown in being confined to the utility model and described specific structure and the scope of application
It is interior, therefore all corresponding modifications that may be utilized and equivalent, belong to the applied the scope of the patents of the utility model.
