Description
Technical field
This utility model relates to water valve design field, particularly relates to a kind of large-diameter flanged connecting valve.
Background technology
Large-diameter flanged connecting valve uses the most common in pipeline engineering, is typically all use in pairs.In pipeline engineering, large-diameter flanged connecting valve is mainly used in the connection of pipeline.Needing the pipeline of connection, a piece of ring flange of various installations, low pressure pipeline can use.Traditional large-diameter flanged connecting valve structure is complicated, typically require special pressure testing device valve bears the ability of hydraulic pressure to test, bother very much, cost is high, therefore a kind of value pressure test of design is convenient, without using special pressure testing device, the deformation sensitive that hydraulic pressure is caused by test blind plate, the large-diameter flanged connecting valve that body strength is high is necessary.
Utility model content
The purpose of this utility model is contemplated to overcome traditional large-diameter flanged connecting valve test hydraulic pressure trouble, the defect that cost is high, devise a kind of large-diameter flanged connecting valve, value pressure test is convenient, without using special pressure testing device, the deformation sensitive that hydraulic pressure is caused by test blind plate, body strength is high.
Solve the technical problem that required by this utility model and can be achieved through the following technical solutions:
A kind of large-diameter flanged connecting valve, including valve body, described valve inner is heavy caliber cavity, hold around and be machined with ring flange respectively, through hole it is drilled with equably on ring flange, connector is used to be connected by both ring flanges when being connected with other part, also include water inlet pipe, test blind plate, sealing ring, bolt, pad, nut, large bore valves, gusset, the internal cavities of described valve body is equipped with described large bore valves, the right-hand member of described valve body uses described bolt, described pad and described nut connect described test blind plate, equipped with described sealing ring between described test blind plate and described valve body, described water inlet pipe is arranged on the center of described test blind plate.
Described test blind plate is the arcuate structure of indent, and after tap water is entered valve body by described water inlet pipe, its inside water pressure causes described test blind plate to deform.
Described test blind plate uses flexible material to make.
Described gusset it is designed with on the outer wall of described valve body.
Owing to have employed above technical scheme, this utility model has the advantage that
Use valve body, water inlet pipe, test blind plate, sealing ring, bolt, pad, nut, large bore valves, gusset combines designed large-diameter flanged connecting valve, test blind plate is the arcuate structure of indent, after tap water is entered valve body by water inlet pipe, its inside water pressure causes test blind plate deformation, heavy caliber connecting valve work pressure test can be readily achieved by the deformation of test blind plate, without using special pressure testing device, test blind plate uses flexible preferably material to make, its deformation sensitive that hydraulic pressure is caused, pressure testing is convenient and swift, it is designed with gusset on the outer wall of valve body, be conducive to improving the intensity of valve body, during valve working, bearing capacity is strong.
Accompanying drawing explanation
Fig. 1 is that this utility model structure forward sight partly cuts open schematic diagram；
In figure each assembly and reference be respectively as follows: 1, water inlet pipe；2, test blind plate；3, sealing ring；4, bolt；5, pad；6, nut；7, large bore valves；8, valve body；9, gusset.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with being specifically illustrating, this utility model is expanded on further.
A kind of large-diameter flanged connecting valve, including water inlet pipe 1, test blind plate 2, sealing ring 3, bolt 4, pad 5, nut 6, large bore valves 7, valve body 8, gusset 9, valve body 8 is internal is heavy caliber cavity, hold around and be machined with ring flange respectively, through hole it is drilled with equably on ring flange, connector is used to be connected by both ring flanges when being connected with other part, the internal cavities of valve body 8 is equipped with large bore valves 7, the right-hand member of valve body 8 uses bolt 4, pad 5 and nut 6 connect test blind plate 2, equipped with sealing ring 3 between test blind plate 2 and valve body 8, good airproof performance, water inlet pipe 1 is arranged on the center of test blind plate 2.
Test blind plate 2 is the arcuate structure of indent, after tap water is entered valve body 8 by water inlet pipe 1, its inside water pressure causes test blind plate 2 to deform, and can be readily achieved heavy caliber connecting valve work pressure test by the deformation of test blind plate 2, it is not necessary to use special pressure testing device.
Test blind plate 2 uses flexible preferably material to make, and its deformation sensitive causing hydraulic pressure, pressure testing is convenient and swift.
Being designed with gusset 9 on the outer wall of valve body 8, be conducive to improving the intensity of valve body 8, during valve working, bearing capacity is strong.
Large-diameter flanged connecting valve disclosed in the utility model, test blind plate 2 is the arcuate structure of indent, after tap water is entered valve body 8 by water inlet pipe 1, its inside water pressure causes test blind plate 2 to deform, heavy caliber connecting valve work pressure test can be readily achieved by the deformation of test blind plate 2, without using special pressure testing device, test blind plate 2 uses flexible preferably material to make, its deformation sensitive that hydraulic pressure is caused, pressure testing is convenient and swift, being designed with gusset 9 on the outer wall of valve body 8, be conducive to improving the intensity of valve body 8, during valve working, bearing capacity is strong.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope, this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
