Abstract
The invention relates to a multi-diameter flanged hydraulic test multifunction device for valves and aims to effectively detect quality of valves and lower potential safety hazards in use. According to the technical scheme, the hydraulic test multifunction device comprises a pressure-bearing device and a pressure lifting device. The pressure-bearing device is provided with a cylindrical pipe cavity formed by a transverse horizontal seamless steel pipe. A first nipple formed by the seamless steel pipe on the cylindrical pipe cavity is connected with valve test connectors different in diameter. The valve test connectors are connected through flanges, metal spiral wound gaskets, blank flanges and high-strength bolts to form a closed structure. The pressure lifting device is provided with a second nipple, and the second nipple formed by a seamless steel pipe is detachably disposed on the lower portion of the cylindrical cavity. The multi-diameter flanged hydraulic test multifunction device for valves is handy and fast, installation quality of a pressure pipeline system is improved, resource waste in production process is reduced, problems such as runoff and leak and production standstill caused by unqualified valve quality in normal operation of a system can be avoided effectively, and the multi-diameter flanged hydraulic test multifunction device for valve is safe and effective.

Technical field
The present invention relates to valve detection equipment, particularly a kind of multi-pipe-diameter flanged valve hydro-test all-in-one.
Background technology
Enhancing day by day along with china's overall national strength, industrialized level also improves constantly, relate to life security, dangerous larger boiler, pressure vessel, pressure pipeline also more and more, valve is guaranteeing that as a kind of important pipe fitting the normal operating effect of pressure pipeline system is also increasing.Be not difficult to find out, the quality of valve mass can directly have influence on the normal production run of system, even can cause stop work and production.How selecting a kind of safe and reliable equipment that the quality of valve is detected, reject the valve that does not meet request for utilization, is a problem demanding prompt solution.
Summary of the invention
For above-mentioned situation, for overcoming the defective of prior art, the present invention's purpose just is to provide a kind of multi-pipe-diameter flanged valve hydro-test all-in-one, can effectively solve the quality that detects valve mass, reduces the problem that has potential safety hazard in use procedure.
The technical scheme that the present invention solves is, comprise pressure-bearing device and pressure lifting device, the cylindrical tube chamber that pressure-bearing device is comprised of the weldless steel tube of transverse horizontal, the first short circuit that consists of through weldless steel tube above cylindrical tube chamber is connected with the valves test joint of different tube diameters, the valves test joint is connected the single head high-strength bolt by flange, SW with outside ring and is connected with blank flange, form enclosed construction, the second short circuit that pressure lifting device consists of through weldless steel tube is loading and unloading type and is placed in cylindrical tube chamber bottom.
Novel structure of the present invention is unique, advantages of simple, cost is low, convenient to use, leakage test and strength test have been carried out valve is conciliate the health check-up maintenance before installation after, the valve that rejecting can't meet the quality requirement, improve the installation quality of pressure pipeline system, reduced the wasting of resources in the production run, can effectively avoid the evaporating, emitting, dripping or leaking of liquid or gas that causes because valve mass is defective in system's normal course of operation, the problem of stop work and production, use safely, effective, good society and economic benefit are arranged.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
Provided by Fig. 1 to Fig. 3, the present invention includes pressure-bearing device and pressure lifting device, the cylindrical tube chamber 3 that pressure-bearing device 1 is comprised of the weldless steel tube of transverse horizontal, the first short circuit 5 that consists of through weldless steel tube above cylindrical tube chamber 3 is connected with the valves test joint 4 of different tube diameters, valves test joint 4 is connected with blank flange by 10 connections of single head high-strength bolt by flange 7, SW with outside ring 8, form enclosed construction, the second short circuit 6 that pressure lifting device 2 consists of through weldless steel tube is loading and unloading type and is placed in cylindrical tube chamber 3 bottoms.
In order to guarantee result of use, on described cylindrical tube chamber 3, tensimeter 11 and water filling gas outlet 12 are housed;
Described tensimeter 11 is contained on cylindrical tube chamber 3 through the 3rd short circuit 13 that weldless steel tube consists of, and the first gate valve 14 and tensimeter bend pipe 15 are housed on the 3rd short circuit 13 successively;
Described water filling gas outlet 12 has the second gate valve 17 for weldless steel tube consists of on water filling gas outlet 12;
Described pressure lifting device 2 is contained on base 18, base 18 is drawn from cylindrical tube chamber 3 front and back, bottoms both sides welding by four isometric angle steel, front-and-back angle steel clamp angle is 60 degree, the angle steel end keeps same level, and be welded to connect successively the rectangularity structure by four angle steel, below base 18, the rectangle structure inboard completely spreads steel plate formation base plate 16, and pressure lifting device 2 is contained on base plate 16;
Through gooseneck 20,2 row's pulley blockss 19 are housed below described base 18.
Described pressure lifting device 2 is the commercially available prod, as hydraulic pump or hydraulic intensifier.
When the present invention uses, at first valve to be tested one end is fixedly connected on valves test joint 4 by single head high-strength bolt 10.During test, valve is in opening, the valve other end is by blank flange 9 sealings, fill with test(ing) medium (normal-temperature water, the kerosene of test(ing) medium for cleaning by water filling gas outlet 12 in pressure-bearing device 1, perhaps non-corrosive liquid medium, when the austenitic stainless steel valve is tested, in water, chloride ion content should be lower than 25ppm), adjusted and the Control experiment pressure by pressure lifting device 2, the pressure by pressure-bearing device 1 in check valve housing exposed surface and duration of test runs changes to judge whether the valve housing test is qualified.During the single-side sealing test, valve is in closed condition, and the logical atmosphere of the other end checks that the pressure of pressure-bearing device 1 in seepage and duration of test runs changes, and requires valve to reach same effect through repeatedly opening and closing.Valve both sides pressure-bearing, the detection respectively in turn that has two way seal to require.The present invention is with lower cost and cost, realized the Performance Detection to valve, guaranteed the quality of mounted valve, reduced the wasting of resources in the production run, the evaporating, emitting, dripping or leaking of liquid or gas that causes because valve mass is defective in the pressure pipeline system operational process, the problem of stop work and production have been avoided, use safely, effective, good society and economic benefit are arranged.
