Description
Technical field
The utility model belongs to value pressure test blind plate field, and in particular to butt welding value pressure test end part combination blind plate.
Background technology
Valve pressure test is to be tested for testing valve by Fluid pressure size, can detect the pressure-resistant matter of valve
Whether amount meets the requirements.Sealed at present in butt welding valve pressure test generally use inner circle O-ring.Different size value pressure test is blind
Plate does not have versatility, and single blind plate is bigger than normal there is structure, very thick and heavy, manufacturing cost greatly and low production efficiency it is scarce
Point.
Utility model content
The purpose of this utility model is that to solve the above problems and provides butt welding value pressure test end part combination blind plate.
The utility model is achieved through the following technical solutions above-mentioned purpose：
Butt welding value pressure test end part combination blind plate, including big blind plate and small blind plate, the big blind plate upper end are provided with positioning
Fixing bolt, the big blind plate are connected by circulation duct with small blind plate, and conduction pipe is provided with the small blind plate center,
Matching slot is provided between the circulation duct and the conduction pipe, the circulation duct is arranged in the big blind plate
Portion.
In said structure, the big blind plate only has one kind, according to the actual requirements, by the small blind plate of required specification and institute
State big blind plate to be connected, and the utility model is securely fitted in by required position by the positioning fixing bolt, by described
Circulation duct, the matching slot and the conduction pipe circulating liquid, conducting pressure.
In order to further improve performance of the present utility model, the big blind plate passes through spiral shell with the positioning fixing bolt
Line assembly connection, the big blind plate are fixedly connected with the circulation duct.
In order to further improve performance of the present utility model, the circumferential location of the big blind plate and the small blind plate adds
Work groove, radial seal is sealed using O-ring.
In order to further improve performance of the present utility model, the circulation duct, the matching slot and the water conservancy diversion
Pipeline communication, the big blind plate only have one.
Beneficial effect is：The utility model can reduce blind plate quantity, and big blind plate only has one kind, installed in testing machine
Upper fixation, small blind plate are arranged on according to the difference of valve specification in the mounting hole of the big blind plate, and technology and pattern assembly is simple, quick
It is convenient, experimentation cost can be reduced.
Brief description of the drawings
Fig. 1 is the constitutional diagram of butt welding value pressure test end part combination blind plate described in the utility model
Fig. 2 is the structure chart of butt welding value pressure test end part combination blind plate described in the utility model.
Description of reference numerals is as follows：
1st, big blind plate；2nd, fixing bolt is positioned；3rd, circulation duct；4th, small blind plate；5th, matching slot；6th, conduction pipe.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As Figure 1-Figure 2, butt welding value pressure test end part combination blind plate, including big blind plate 1 and small blind plate 4, on big blind plate 1
End is provided with positioning fixing bolt 2, and big blind plate 1 is connected with small blind plate 4 by circulation duct 3, is provided with the small center of blind plate 4
Conduction pipe 6, is provided with matching slot 5 between circulation duct 3 and conduction pipe 6, circulation duct 3 is arranged on the middle part of big blind plate 1.
In said structure, big blind plate 1 only has one kind, according to the actual requirements, by the small blind plate 4 of required specification and big blind plate 1
It is connected, and the utility model is securely fitted in required position by positioning fixing bolt 2, passes through circulation duct 3, matching slot
5 and the circulating liquid of conduction pipe 6, conducting pressure.
In order to further improve performance of the present utility model, big blind plate 1 passes through Screw assembly with positioning fixing bolt 2
Big blind plate 1 can be fixedly mounted on testing machine by connection, positioning fixing bolt 2, and big blind plate 1 is fixedly connected with circulation duct 3,
The circumferential location processing groove of big blind plate 1 and small blind plate 4, radial seal is sealed using O-ring, can by big blind plate 1 with it is small blind
Plate 4 is tightly connected, and avoids pressure release, causes test failure, and circulation duct 3, matching slot 5 connect with conduction pipe 6, can conduct pressure
Power, big blind plate 1 only have one, while match small blind plate 4 have it is multiple, cost can be reduced.
General principle, principal character and advantage of the present utility model has been shown and described above.The technical staff of the industry
It should be appreciated that the utility model is not restricted to the described embodiments, the simply explanation described in above-described embodiment and specification is originally
The principle of utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model also has various change
And improvement, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model requires protection scope
Defined by appended claims and its effect thing.
