Abstract
A sealing device for valve pressure test under reaction force belongs to the field of valve pressure test equipment. The sealing device is characterized in that the device comprises a sealing base (5), a sealing plate (3) and a sealing ring (1), wherein the sealing base (5) is concave, and a pressure test connection hole (6) is formed below the sealing base (5); the sealing plate (3) is a circular plate, a pressure test hole (2) is formed at the center of the sealing plate (3), and a sealing groove (4) is formed at the periphery of the sealing plate (3); the sealing ring (1) is mounted in the sealing groove (4); and the sealing plate (3) is mounted in the sealing base (5). The device has the advantages of simple processing, simple operation and less time and labor, and can be made into different specifications and grades according to different requirements, thereby saving manufacture cost and manpower for pressure test and increasing the speed of the valve pressure test.
Description
Technical field
Valve pressure testing reacting force packoff belongs to valve pressure testing apparatus field, is applicable to the sealing when the every profession and trade flange connects the valve pressure testing.
Background technology
Though valve is in preceding 100% the strictness check of having passed through of dispatching from the factory, owing to the vibration of transportation, factors such as carrying, difference variation.Most valves all get when installing and check its sealing property again, mainly are the sealings at valve body sealing surface and packing place.If directly install without pressure testing, in case leaking to stop production, generation reinstalls, cause heavy losses to enterprise.
My company's valve pressure testing is to use lifting jack to finish on homemade pressure platform mostly, and its method is simple, practical.But during the big specification valve of test, need the lifting jack with 20T～100T, the several people firmly exerts pressure simultaneously and valve pressure testing sealing surface could be sealed, and this method labour intensity is big, when taking a lot of work; Though the valve pressure testing hydraulic test bench that specialized factory makes is laborsaving, speed is slower, costs an arm and a leg the engineering cost height.
The utility model content
The technical problems to be solved in the utility model is, overcomes the problem that prior art exists, and it is simple, easy and simple to handle, time saving and energy saving to design a kind of processing, and can improve the reacting force packoff of valve pressure testing speed.
The technical scheme that its technical matters that solves the utility model adopts is: valve pressure testing reacting force packoff, it is characterized in that: comprise sealing socket, seal pad and O-ring seal, sealing socket is a spill, the below is provided with the pressure testing connecting hole, seal pad is a plectane, and the center is provided with the pressure testing hole, and periphery is provided with seal groove, O-ring seal is installed in the seal groove, and seal pad is installed in the spill sealing socket.
For being slidingly matched, build-up tolerance is 0.04-0.1mm to seal pad with sealing socket.
Valve pressure testing reacting force packoff is to utilize the reacting force principle to carry out work, makes pressure testing device reach good sealing effectiveness.
Compared with prior art, the pressure testing of the utility model valve with the beneficial effect that the reacting force packoff is had is: process simple, easy and simple to handle, time saving and energy saving, and can be made into the different size grade according to different needs, saved the manpower of manufacturing expense and pressure testing, improved the speed of valve pressure testing, efficiently solve in the valve pressure testing process take a lot of work, time-consuming drawback, brought into play positive role in the valve pressure testing at the scene, obtained extraordinary effect.
Description of drawings
Fig. 1 valve pressure testing reacting force schematic diagram of sealing device;
Fig. 2 valve pressure testing application synoptic diagram of reacting force packoff on pressure testing machine.
Fig. 1-2 is a preferred example of the present utility model, wherein: 1 O-ring seal, 2 pressure testing holes, 3 seal pads, 4 seal grooves, 5 sealing sockets, 6 pressure testing connecting holes, 7 handles, 8 power transmission leading screws, 9 work pressure test platforms, 10 pressure testing valves, 11 gasket seals, 12 seal pads.
Embodiment
Pressure testing is described further with the reacting force packoff to the utility model valve below in conjunction with accompanying drawing 1-2:
The utility model valve pressure testing reacting force packoff, comprise: O-ring seal 1, pressure testing hole 2, seal pad 3, seal groove 4, sealing socket 5, pressure testing connecting hole 6, pressure testing hole 2 is on seal pad 3 coaxial cables, seal groove 4 is at the periphery of seal pad 3, sealing socket 5 is a spill, the below is provided with pressure testing connecting hole 6, and O-ring seal 1 is installed in the seal groove 4, and seal pad 3 is installed in the spill sealing socket 5.Seal pad 3 and spill sealing socket 5 are for being slidingly matched, and build-up tolerance is 0.04-0.1mm.
The utility model valve pressure testing application of reacting force packoff.
During use, pressure testing valve 10 is put in the work pressure test platform 9, pressure testing valve 10 upper end sealing surfaces connect through gasket seal 11 and 12 seal pads, pressure testing valve 10 lower end sealing surfaces are connected with the reacting force packoff with the valve pressure testing through gasket seal 11, with handle 7 reinforcings, make 10 sealed at both ends on pressure testing valve at the normal pressure lower seal through power transmission leading screw 8, open test pump water filling pressurization in pressure testing valve body 10 again through pressure testing connecting hole 6, pressure testing hole 2.Along with pressure testing valve body 10 internal pressures raise, reacting force packoff internal pressure raises together, and relies on the interior pressure that produces of reacting force packoff with the sealed at both ends face seal of valve.Because the suffered power of reacting force packoff is that equal and opposite in direction, direction are opposite with the reacting force of pressure testing valve body 10 inside, decrement for gasket seal 11 and pressure testing valve body 10, the reacting force packoff can replenish at any time, so can be effectively the 10 sealed at both ends face seals of pressure testing valve.When 10 tests of pressure testing valve finished pressure release, the reacting force packoff also returned to the normal position simultaneously.
The above, it only is preferred embodiment of the present utility model, be not to be the restriction of the utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away from.To any simple modification, equivalent variations and remodeling that above embodiment did, still belong to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
