The utility model discloses a kind of all-welded ball valve assembling pressure testing all-in-one, comprise the frame body (2) be made up of two circular guideways (1), it is characterized in that: described frame body (2) bottom is provided with guide rail (3), guide rail (3) is provided with travelling table (4), travelling table (4) is provided with instrument connection (41), travelling table (4) one end is provided with hydraulic jack A(5), hydraulic jack A(5) by piston rod A(51) be flexibly connected with travelling table (4), frame body (2) top is provided with hydraulic jack B(7), hydraulic jack B(7) by piston rod B(71) be fixedly connected with pressing plate (8), the utility model efficiently solves existing all-welded ball valve in machining process, need pressure testing operation, without professional pressure testing equipment, test pressure majority is difficult to reach predetermined value, thus the problem causing product percent of pass low.
Description
Technical field
The utility model relates to machining apparatus technical field, is specifically related to a kind of all-welded ball valve assembling pressure testing all-in-one.
Background technology
The valve body part of traditional cast steel ball valve is bolted by valve body and valve gap and forms, the two ends of valve body mostly are flange arrangement, also with bolts, but after long-term engineering application, find that the phenomenon of leaking often appears in bolt junction, thus affect the safe operation of pipe-line system.People had invented all-welded ball valve afterwards, all-welded ball valve adopts all-welded structure, valve body by girth joint by main valve body and lateral body integrally welded, the inside and outside sealing of valve is greatly improved, valve weight obtains very large reduction, make the installation of valve become more convenient, not only reduce the cost of engineering construction, also save the time.Therefore all-welded ball valve just at fast fetching for traditional cast steel ball valve, market prospects are very good.Tradition all-welded ball valve in the fabrication process, before weldering, pressure testing, spot welding method of operating be generally adopt blind plate screw and tightly make valve seat preloading spring be in designing requirement, some summaries advanced any be adopt hydraulic press to compress, but valve is extremely required great effort when entering hydraulic press, and do not consider the pressure that hydraulic cylinder uses, at will adopt hydraulic cylinder top once often, the pressure of sealing pressure testing should be 1.1 times of design, a lot of only use 0.4MPA pressure testing, the valve postwelding of spot welding has been revealed also has 20%.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of all-welded ball valve assembling pressure testing all-in-one, the utility model efficiently solves existing all-welded ball valve in machining process, need pressure testing operation, without professional pressure testing equipment, test pressure majority is difficult to reach predetermined value, thus the problem causing product percent of pass low.
The utility model is achieved through the following technical solutions:
A kind of all-welded ball valve assembling pressure testing all-in-one, comprise the frame body (2) be made up of two circular guideways (1), it is characterized in that: described frame body (2) bottom is provided with guide rail (3), guide rail (3) is provided with travelling table (4), travelling table (4) is provided with instrument connection (41), travelling table (4) one end is provided with hydraulic jack A(5), hydraulic jack A(5) by piston rod A(51) be flexibly connected with travelling table (4), frame body (2) top is provided with hydraulic jack B(7), hydraulic jack B(7) by piston rod B(71) be fixedly connected with pressing plate (8).
The further Technological improvement plan of the utility model is:
Described pressing plate (8) two ends are provided with through hole (6), are slidably connected with two circular guideways (1) of frame body (2).
The further Technological improvement plan of the utility model is:
Fixed by connecting plate (9) between described two circular guideways (1), pressing plate (8) is arranged on the circular guideway (1) of connecting plate (9) below.
The further Technological improvement plan of the utility model is:
The utility model compared with prior art, there is following obvious advantage: the utility model adopts travelling table to put the valve body welded, be pushed directly to below pressing plate, by pressing plate for sealing valve body two side ends, and air admission hole I and the steam vent by travelling table is arranged, the sealing property of test valve body, not only reduce the labour intensity of operating personnel, and improve the measuring accuracy of valve seal performance, pressure testing point postwelding, the valve leaks of welding controls within 2%, substantially increases the yield rate of product.The pressure testing spot welding kludge of my company designs can more than pressure testing 10MPA, can reach the normal pressure testing instructions for use of valve completely, so product qualified rate is high;
The utility model applicability is comparatively strong, according to valve different size, adopts the method adjustable pressure size controlling oil pressure, can make a tractor serves several purposes, multiplex from 200 series-1200 series one.
Accompanying drawing explanation
Fig. 1 is the utility model pressure testing pre-structure schematic diagram;
Fig. 2 is the structural representation after the utility model pressure testing.
Detailed description of the invention
As shown in Figure 1, 2, the utility model comprises the frame body 2 be made up of two circular guideways 1, guide rail 3 is provided with bottom described frame body 2, guide rail 3 is provided with travelling table 4, travelling table 4 is provided with instrument connection 41, and travelling table 4 one end is provided with hydraulic jack A5, and hydraulic jack A5 is flexibly connected with travelling table 4 by piston rod A51, frame body 2 top is provided with hydraulic jack B7, and hydraulic jack B7 is fixedly connected with pressing plate 8 by piston rod B71.
Described pressing plate 8 two ends are provided with through hole 6, are slidably connected with two circular guideways 1 of frame body 2.
Fixed by connecting plate 9 between described two circular guideways 1, pressing plate 8 is arranged on the circular guideway 1 below connecting plate 9.
Composition graphs 1,2 sketches the course of work of the present utility model:
First spot welding and the valve body 10 that assembles are positioned on travelling table 4, travelling table 4 draws in bottom hydraulic press center and pressing plate 8 by piston rod A51 by hydraulic jack A5, then primer fluid compressing cylinder B7, hydraulic jack B7 is with dynamic pressure plate 8 to compress valve 10 by piston rod B71, make valve 10 seating spring pre-pressing force be in designing requirement, then carry out pressure testing by test pore 41.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art and is realized.
