It is dynamic.After pressure oil tank builds pressure, is verified again because of safety valve malfunction, will cause claim for eot.
Utility model content
The purpose of this utility model is that being directed to the above problem in the prior art, provide a kind of safety valve inspection dedicated dress
Set, pressure oil tank build pressure in advance examine safety valve whether malfunction, can be built to avoid pressure oil tank pressure after because of safety valve malfunction, make
The problem of at claim for eot.
To realize above-mentioned purpose of utility model, the utility model uses following technical solution：
A kind of safety valve inspection dedicated unit, including passing sequentially through air inlet control needle valve, the exhaust that pipeline connects
Needle valve and gas gauge；One end of the air inlet control needle valve is connected by high-pressure hose with high-pressure air source, the other end
Connected respectively with exhaust needle valve and the second three-way connection by the first three-way connection, the other both ends difference of the second three-way connection
Connect with gas gauge and safety valve to be measured.
The exhaust ports of above-mentioned exhaust needle valve are equipped with silencer.
Above-mentioned second three-way connection is connected by safety valve flange with safety valve air inlet to be measured.
Above-mentioned air inlet control needle valve is connected by high-pressure hose connector with high-pressure hose.
Above-mentioned gas pressure gauge uses 0.2 grade of digital display manometer.
Above-mentioned air inlet control needle valve, the rated pressure for being vented needle valve, the first three-way connection and the second three-way connection are equal
For 10MPa, and it is made of stainless steel material.
Compared with the prior art, the advantage of the utility model is：
The utility model disclose a kind of safety valve examine dedicated unit, by air inlet control needle valve, exhaust needle valve and
Gas gauge is connected by pipeline, can be during transportation using high-pressure air source detection safety valve valve rod at the scene
No loosening.The utility model structure is simple, and it is convenient to install and use, and builds pressure in pressure oil tank and checks safety valve in advance, solves pressure
The problem of power oil tank is built after pressure because of safety valve malfunction, and claim for eot is caused；It also can avoid causing stress because of safety valve advancement
The problem of normal pressure value is not achieved in tank pressure, causes pressure oil pump, automatic air supply device frequent starting, and then improve equipment
Service life and safety.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that a kind of safety valve of the utility model examines dedicated unit.
Appended drawing reference：1-high-pressure hose connector, 2-air inlets control needle valve, the 3-the first three-way connection, and 4-the two three
Pass joint, 5-safety valve flanges, 6-exhaust needle valves, 7-silencers, 8-gas gauges, 9-safety valves to be measured,
10-high-pressure air sources, 11-high-pressure hoses.
Specific embodiment
With reference to embodiments and its attached drawing is further non-limitingly described in detail technical solutions of the utility model.
As shown in Figure 1, a kind of safety valve examines dedicated unit, needle is controlled including passing sequentially through the air inlet that pipeline connects
Type valve 2, exhaust needle valve 6 and gas gauge 8；One end that air inlet controls needle valve 2 passes through high-pressure hose 11 and high-pressure air source
10 connect, and the other end is connected with exhaust needle valve 6 and the second three-way connection 4 respectively by the first three-way connection 3, and the two or three connects
First 4 other both ends connect with gas gauge 8 and safety valve to be measured 9 respectively；High-pressure air source is used to mention for detection safety valve
Air supply source；It is more convenient for connecting with high-pressure air source using high-pressure hose, operating flexibility is stronger；It is vented the exhaust ports of needle valve 6
Noise is reduced for eliminating the noise when being vented needle-like valve exhaust equipped with silencer 7；It is soft by high pressure that air inlet controls needle valve 2
Pipe fitting 1 connects with high-pressure hose 11, convenient for quick installation；Second three-way connection 4 passes through safety valve flange 5 and safety to be measured
9 air inlet of valve connects.
Gas gauge 8 uses 0.2 grade of digital display manometer.
The rated pressure that air inlet controls needle valve 2, exhaust needle valve 6, the first three-way connection 3 and the second three-way connection 4 is equal
For 10MPa, and it is made of stainless steel material, it is durable.
Pipeline is welded with argon arc welding, and is cleaned up.
A kind of safety valve of the utility model examines the course of work of dedicated unit：
After verification gas gauge is qualified, the both ends of high-pressure hose are controlled into needle valve with high-pressure air source and air inlet respectively
Connect；The second three-way connection is connected by safety valve flange with safety valve air inlet to be measured again；Exhaust needle valve is closed, is delayed
Slow air inlet control needle valve of opening is closed after a certain period of time；Ne-leakage is confirmed with the soaked inspection safety valve flange of soap and each interface
Afterwards, it opens air inlet control needle valve to continue to boost, during which observes the reading of gas gauge, when pressure is more than that pressure oil tank is specified
Pressure and be lower than safety valve action pressure value when, close air inlet control needle valve, observation safety valve whether act, if movement indicate
Safety valve valve rod loosens and leads to advancement, cannot be used continuously；If being failure to actuate indicates that safety valve valve rod does not loosen, can
To install and use；After to be tested, open exhaust needle valve and carry out pressure release, after the discharge of gas in pipeline, complete
Entire checked operation.
