Abstract

The utility model relates to a mechanical connection technical field specifically is an auxiliary locking device for valve compression test, including pressure test machine, the last connection pad that is connected with of pressure test machine, the connection pad coils through screw fixed connection with sealed, connection pad and sealed dish between be equipped with to lead to and press the hole, the sealed portion of trying to get to the heart of a matter is equipped with sealed dish unable adjustment base, the level that is equipped with on the sealed dish unable adjustment base is to the guide rail, the sealed portion of trying to get to the heart of a matter be equipped with with the lug of level to guide rail looks adaptation, realize that the slip is fixed between the sealed portion of trying to get to the heart of a matter and the sealed dish unable adjustment base to it is fixed via the lock bolt. Compared with the prior art, the utility model, its advantage lies in the utility model discloses a connection pad is connected with pressure test machine, and sealed dish is connected with the connection pad, and processing has to lead to and presses the hole between sealed dish and the connection pad, when guaranteeing the valve pressure testing connection pad with seal up coil between pressure balance, do not need the extra locking force of hydro -cylinder increase, safety when guaranteeing valve compression test.

Description

A kind of additional locking devices for valve pressure test
[technical field]
This utility model is related to mechanical connecting device technical field, specifically a kind of auxiliary lock for valve pressure test Tight device.
[background technology]
With the raising of the feed-lines such as natural gas, oil, chemical industry, environmental protection and vapour storage device design and processes level, The usage amount of high-pressure large-caliber valve rises year by year, and the sales volume of valve manufacture producer high-pressure large-caliber valve is increasingly improved, right The design of producer, production are proposed new requirement.
Before valve is devoted oneself to work, needs carry out strict pressure test in pressure experimental device.The mesh of pressure test Be check pressure vessel pressure-containing member intensity and tightness.In process of the test, by observing pressure-containing member whether there is substantially Deformation ruptures to verify whether pressure vessel has bearing capacity necessary to safe operation under design pressure.Meanwhile, pass through There is ne-leakage the junctions such as observation weld seam, flange, check the tightness of pressure vessel.Pressure examination is carried out in high-pressure large-caliber valve When testing, because casing rigidity test pressure is 1.5 times of valve design pressure, when causing valve to carry out Shell test, pressure testing machine When high-pressure section is proceeded to, pressure testing machine two ends closure can increase pressure testing machine locking to closure in the presence of total force The load of oil cylinder, causes oil cylinder locking power not enough, makes valve occur closure disengaging, the spray of high pressure test medium during pressure testing The dangerous situation for going out is produced.
[utility model content]
The purpose of this utility model is exactly easy in process of the test in order to solve valve pressure testing device of the prior art There is the not enough and defect of the dangerous situations such as closure disengaging, there is provided a kind of structure is novel, safe and reliable, can effectively lock pressure testing The additional locking devices for valve pressure test of auxiliary device, including pressure testing machine, are connected with terminal pad on pressure testing machine, connection Disk is fixedly connected with seal disc by screw, and logical pressure hole is provided between described terminal pad and seal disc;The sealing tray bottom Be provided with seal disc firm banking, the seal disc firm banking is provided with horizontal direction guiding rail, sealing tray bottom be provided with level to The projection that guide rail is adapted, realizes being slided between sealing tray bottom and seal disc firm banking and fixes, and solid via lock bolt It is fixed.
The upper and lower surface of seal disc is respectively equipped with two grooves, and sealing ring, described seal disc are provided with groove On be additionally provided with fixing hole.
Sealing ring is RUBBER O type sealing ring.
Described terminal pad includes disk body, and described disk body center is provided with axis hole and is connected with testing machine by axis hole, Fixing hole is provided with around described disk body, the fixing hole position is corresponding with the fixing hole position on seal disc.
Some groups of corresponding grooves and projection are respectively equipped with connecting end surface of the terminal pad with seal disc, it is convex during connection Block and groove are meshed and are connected by screw.
The connecting end surface of described seal disc is provided with 47 groups of corresponding grooves and projection.
This utility model compared with the existing technology, has an advantage in that terminal pad of the present utility model is connected with pressure testing machine, close Closing disk is connected with terminal pad, logical pressure hole is machined between seal disc and terminal pad, it is ensured that terminal pad and seal disc during value pressure test Between pressure balance, it is not necessary to oil cylinder increases extra coupling mechanism force, it is ensured that safety during valve pressure test;The seal disc is consolidated Determine the horizontal direction guiding rail that base is provided with, it is possible to achieve slide between sealing tray bottom and seal disc firm banking and fix, it is more sharp In detection.
[description of the drawings]
Fig. 1 is this utility model embodiment pressure test additional locking devices structural representation;
Fig. 2 is that this utility model embodiment pressure test auxiliary device applies the working condition on pressure experimental device to tie Structure schematic diagram;
Description of symbols in figure:
1. terminal pad, 2. seal disc, 3. sealing ring, 4. attachment screw, 5 projections, 6 lock bolts are fixed, 7 horizontal guides Rail.
[specific embodiment]
Below in conjunction with the accompanying drawings the utility model is described in further detail, the structure and principle of this device people professional to this For be very clearly.It should be appreciated that specific embodiment described herein is only to explain this utility model, and without In restriction this utility model.
As shown in Figure 1 and Figure 2, a kind of pressure test auxiliary device, it includes terminal pad and seal disc, is connected by screw, Between have sealing ring to ensure sealing, logical pressure hole is machined between terminal pad and seal disc, it is ensured that pressure balance when device works, keep away Exempt from unexpected generation.The sealing tray bottom is provided with seal disc firm banking, and the seal disc firm banking is provided with horizontal guide Rail, sealing tray bottom is provided with the projection being adapted with horizontal direction guiding rail, realizes between sealing tray bottom and seal disc firm banking Slide and fix, and fix via lock bolt.
When in use, terminal pad is connected with pressure testing machine first, is installed by the way that the axis hole of terminal pad is corresponding with pressure testing machine, so It is connected and sealed by seal disc afterwards.The upper and lower surface of seal disc is respectively equipped with two grooves, is provided with groove close Seal, sealing ring is preferably RUBBER O type sealing ring.Terminal pad is corresponding with being respectively equipped with some groups on the connecting end surface of seal disc Groove and projection, preferably have 4~7 groups, projection and groove are meshed and are connected by screw during connection.
When pressure testing machine is tested, sealed with the cooperation of seal disc by terminal pad, pressure testing machine closure is entering When row is to high-pressure section, pressure testing machine two ends closure in the presence of total force, can increase the load of pressure testing machine locking cylinder, Oil cylinder locking power ensures degree of blocking under the cooperation of this utility model device, makes valve ensure sealing during pressure testing, will not There is the dangerous situation that high pressure test medium sprays to produce, it is safe and reliable.
