Abstract
The utility model discloses a simple and easy pressure testing anchor clamps of heavy -calibre valve, including two closing plates, two anchor clamps curb plates, a plurality of big screw rod, a plurality of big nut, connector and entrance pressure pipes, two closing plates are established respectively on the mouth of the both ends of valve, be equipped with the anchor clamps curb plate on the lateral surface of two closing plates respectively, two anchor clamps curb plates compress tightly two closing plates through the cooperation of big screw rod with big nut, are equipped with the through -hole on the preceding closing plate, be equipped with the connector on the through -hole, the entrance pressure pipe is connected with the connector, compares with prior art, the utility model discloses can avoid the valve atress to warp low in production cost to simple structure, convenient operation.
Description
[technical field]
The utility model relates to the technical field of fixture, particularly the technical field of the simple and easy pressure test fixture of a kind of large bore valves.
[background technology]
Because not resembling conventional RF flange valve and easily clamping during BW butt welded end valve pressure testing, thus more difficult during pressure testing. Many enterprises are all to the customized special plane of pressure testing equipment factory to carry out pressure testing for small-bore BW end valve door; And pressure testing for heavy caliber BW end valve door is extremely difficult especially, in addition due to the heavy caliber order quantity of BW end valve door own just seldom, if going the customized expensive special plane will without any economic worth again. And the clamping of special plane withstands valve by external force from two ends, valve is very easily formed stress deformation.
[practical novel content]
The purpose of this utility model solves the problems of the prior art exactly, it is proposed to a kind of simple and easy pressure test fixture of large bore valves, it is possible to avoiding valve stress deformation, production cost is low, and structure is simple, easy to operate.
For achieving the above object, the utility model proposes a kind of simple and easy pressure test fixture of large bore valves, comprise two sealing plates, two fixture side plate, some big screw rods, some big nuts, connecting joints and enter pressure pipe, described two sealing plates are located in the two-port of valve respectively, described two sealing plates outer side is respectively equipped with fixture side plate, two sealing plates are carried out compressing by described two fixture side plate by the cooperation of big screw rod and big nut, it is provided with through hole on front sealing plate, described through hole is provided with connecting joint, described in enter pressure pipe and be connected with connecting joint.
As preferably, the upper and lower of described two fixture side plate all wears and is provided with big screw rod, described big screw rod is equipped with big nut in the outside of two fixture side plate.
As preferably, described sealing plate inner side be provided with the grafting body matched with valve port, be provided with sealing-ring between described grafting body and valve inwall.
The beneficial effects of the utility model: the utility model utilizes the outer mode tapping into pressure pipe, only provide the coordinating of fixture side plate, big screw rod and big nut less power keep sealing plate sealing, substantially can ignore so the stress deformation of valve itself is affected. Compared with prior art, it is possible to avoiding valve stress deformation, production cost is low, and structure is simple, easy to operate.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the structural representation of the utility model simple and easy pressure test fixture of a kind of large bore valves.
In figure: 1-valve, 2-sealing plate, 3-fixture side plate, the big screw rod of 4-, 5-big nut, 6-connecting joint, 7-enter pressure pipe, 8-through hole, 9-grafting body, 10-sealing-ring.
[embodiment]
Consult Fig. 1, a kind of simple and easy pressure test fixture of large bore valves of the utility model, comprise two sealing plates 2, two fixture side plate 3, some big screw rods 4, some big nuts 5, connecting joint 6 and enter pressure pipe 7, described two sealing plates 2 are located in the two-port of valve 1 respectively, the outer side of described two sealing plates 2 is respectively equipped with fixture side plate 3, two sealing plates 2 are compressed by described two fixture side plate 3 by the cooperation of big screw rod 4 and big nut 5, through hole 8 it is provided with on front sealing plate, described through hole 8 is provided with connecting joint 6, described enter pressure pipe 7 be connected with connecting joint 6, the upper and lower of described two fixture side plate 3 all wears and is provided with big screw rod 4, described big screw rod 4 is equipped with big nut 5 in the outside of two fixture side plate 3, the grafting body 9 that the inner side of described sealing plate 2 is provided with valve 1 port matches, it is provided with sealing-ring 10 between described grafting body 9 and valve 1 inwall.
The utility model working process:
A kind of simple and easy pressure test fixture of large bore valves of the utility model is in working process, two sealing plates 2 are plugged in the two-port of valve 1 respectively, then by the cooperation of fixture side plate 3, big screw rod 4 and big nut 5, sealing plate 2 is compressed, then enter pressure pipe 7 to boosting in valve 1. The utility model utilizes the outer mode tapping into pressure pipe 7, and coordinating of fixture side plate 3, big screw rod 4 and big nut 5 only provides less power to keep the sealing of sealing plate 2, so the stress deformation impact of valve 1 itself substantially can be ignored. Compared with prior art, it is possible to avoiding valve stress deformation, production cost is low, and structure is simple, easy to operate.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any scheme after the utility model simple transformation is all belonged to protection domain of the present utility model.
