Technical field
The utility model relates to a kind of verifying attachment, and especially a kind of safety valve erecting device of check-out console belongs to the technical field of safety valve testing.
Background technology
The verification of safety valve off-line refers to pulls down safety valve from protected equipment, its set-pressure adjustment, within requiring the acceptability limit of set-pressure, and is carried out to experiments of sealing performance, to guarantee that safety valve can open in time and not reveal.Be called safety valve checkout platform (hereinafter to be referred as checking table) for the equipment of the adjustment of safety valve setting pressure and experiments of sealing performance, it installs (clampings) device two large divisions formation by console and safety valve.
The feature that the safety valve of existing checking table is installed (clamping) device is: screw thread safety valve (referring to that the air intake opening of safety valve and the pipeline enclosure of protected equipment adopt thread connecting mode) and flange safe valve (referring to that the air intake opening of safety valve and the pipeline enclosure of protected equipment adopt flange connection) all use the clamping station of the same side that is positioned at console.Even if the very little screw thread safety valve of verification also needs operating personnel to leave console to side clamping, adjustment safety valve, make troubles to verification operation, and affect work efficiency.The clamping of flange safe valve adopts three uniform claws on circumference to realize the clamping to safety valve.And for some American Standard safety valve, pilot operated safety valve, three-jaw cannot reach on safety valve inlet flange safety valve is clamped simultaneously, verifying work is often met difficulty.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of safety valve erecting device of checking table is provided, and it is simple and compact for structure, easy to install, improves the efficiency of verification, expands the scope of application, safe and reliable.
The technical scheme providing according to the utility model, the safety valve erecting device of described check-out console, comprises console; Be provided with screw thread safety valve check seat and clamping platform in one end of described console, the contiguous console of described screw thread safety valve check seat, clamping platform is positioned at the outside of screw thread safety valve check seat; On screw thread safety valve check seat, screw thread safety valve joint is set, clamping platform is provided with four mobile claws.
Described clamping platform is provided with T-shaped frid, and described T-shaped frid is provided for installing the T-shaped groove of claw, and the shape of described T-shaped groove and the shape of claw match, and claw can move after being arranged in T-shaped groove on T-shaped frid.
Described T-shaped groove is symmetric on T-shaped frid.
Described console is provided with verification valve, and the gas outlet of described verification valve is connected by wireway and screw thread safety valve joint and the flange safe valve that is positioned on clamping platform.
Described console is provided with some precision pressure gauges.The bottom of described console is provided with leg.
Advantage of the present utility model: the screw thread emergency valve seat by configuration near console, makes the work of screw thread safety valve testing become more convenient, quick; The T-shaped frid of clamping platform has four T-shaped grooves, both can be with three claw, also can adopt two symmetrical claws to clamp safety valve, and make the scope of application of device larger, simple and compact for structure, improve the efficiency of verification.

Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, Figure 2 and Figure 3: in order conveniently to carry out verification to safety valve, improve convenience and the efficiency of verification operation, the utility model comprises console 1; Be provided with screw thread safety valve check seat 5 and clamping platform 8 in one end of described console 2, described screw thread safety valve check seat 5 contiguous consoles 1, clamping platform 8 is positioned at the outside of screw thread safety valve check seat 5; On screw thread safety valve check seat 5, screw thread safety valve joint 4 is set, clamping platform 8 is provided with four mobile claws 6.
Particularly, the bottom of described console 1 is provided with leg 10, and described console 1 is provided with some precision pressure gauges 2, can show various required force value by precision pressure gauge 2, and the center section of console 1 is operating surface 12.In the utility model embodiment, screw thread safety valve joint 4 is female adapter, screw thread safety valve check seat 5 is fixedly installed on the right side of console 1, and clamping platform 8 is positioned at the right side of screw thread safety valve check seat 5, between screw thread safety valve check seat 5 and clamping platform 8, connects by wireway 9.
Described clamping platform 8 is provided with T-shaped frid 7, and described T-shaped frid 7 is provided for installing the T-shaped groove 11 of claw 6, and the shape of the shape of described T-shaped groove 11 and claw 6 matches, and claw 6 is arranged on T-shaped groove 11 and can on T-shaped frid 7, moves after interior.
Described T-shaped groove 11 is symmetric on T-shaped frid 7.On T-shaped frid 7, there is the axis of two T-shaped grooves 11 to be located along the same line, be used for placing flange safety valve in the joint portion of two T-shaped grooves 11.Two other T-shaped groove 11 is symmetrically distributed in the both sides of above-mentioned two T-shaped grooves 11, and these two T-shaped grooves 11 are acute angle with the angle of two T-shaped grooves 11 of axis on same straight line.Each T-shaped groove 11 is interior to be arranged one and can, at the claw 6 of described T-shaped groove 11 interior movements, coordinate by the mobile of claw 6, can realize and realize being fixed of 6 of two claws 6, three claws 6 or four claws to being arranged on flange safe valve on clamping platform 8.In the utility model embodiment, claw 6 can adopt existing version.
Described console 1 is provided with verification valve 3, and the gas outlet of described verification valve 3 is connected by wireway 9 and screw thread safety valve joint 4 and the flange safe valve that is positioned on clamping platform 8.
When verification, screw thread safety valve is screwed on the screw thread safety valve joint 4 of safety valve check seat 5; By changing (interior) threaded connector of different size, can complete the verification of the screw thread safety valve of various different sizes (bore).Due to screw thread safety valve check seat 5 sides that are arranged near console 1, while making verification Thread valve, operating personnel can not leave console 1 and complete verifying work, not only convenient and swift, but also time saving and energy saving.
On clamping platform 8, dispose T-shaped frid 7, claw 6 can be filled in the T-shaped groove of T-shaped frid 7 and slide, to adapt to the safety valve of different sizes (bore).When verification, safety valve is placed on T-shaped frid 7, claw 6 is closed up to the inlet flange safety valve upper surface that is stuck in safety valve, flange safe valve (cushion block of sealing use is arranged at bottom) is installed in the oil cylinder jack-up of clamping platform 8 bottoms, can starts verification after tightly being blocked by claw 6.On T-shaped frid 7, open four T-shaped grooves, made not only can use three claws 6, but also can use aspectant two claws to carry out work, can adapt to the safety valve of wide variety of shapes.
