Description
Technical field
The utility model relates to the minimum engaging pressure proving installation of a kind of valve.
Background technology
Along with the fast development of valve gate technology, the examination criteria of valve industry is more and more stricter, not only detects valve intensity and high pressure sealing, and carries out mandatory provision to the factory testing of the minimum engaging pressure of each valve.And water closing presure as minimum in composite exhaust valve is 0.02MPa (i.e. 2 meter water columns), the minimum opening pressure numerical value of axial flow type check valve standard regulation is 2KPa(i.e. 20 centimeter water columns), the measuring technology personnel of high-accuracy testing tool and specialty need be configured, just can complete testing.The quantity that need detect valve often hundreds of, to several thousand, takes a large amount of man power and materials.
Summary of the invention
In order to overcome the deficiencies in the prior art, primary and foremost purpose of the present utility model is to provide a kind of measuring technology personnel without the need to configuring high-accuracy testing tool and specialty, just can test the minimum engaging pressure proving installation of valve of the minimum engaging pressure of valve accurately, efficiently, concrete scheme of the present utility model is as follows for achieving the above object:
The minimum engaging pressure proving installation of a kind of valve, comprises fixed support, and described fixed support is provided with the flange for connecting valve to be measured and has the container of height Presentation Function; Be connected with pipeline below described flange, described pipeline is communicated with described container bottom, and described pipeline is provided with the second ball valve.
Preferably, described flange and described container bottom are positioned at same level height.
Preferably, described container is the graduated transparent glass tube of tool.
Preferably, also comprise feed tube, described feed tube and described pipeline connection, described feed tube is also provided with water pump and the first ball valve.
Preferably, described container bottom is provided with the 3rd ball valve.
The valve that the utility model provides minimum engaging pressure proving installation, without the need to configuring the measuring technology personnel of high-accuracy testing tool and specialty, just can test the minimum engaging pressure of valve accurately, efficiently.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms a application's part, does not form improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is the utility model example structure schematic diagram.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.
Embodiment
As shown in Figure 1, the minimum engaging pressure proving installation of a kind of valve, comprises fixed support 7, and described fixed support 7 is provided with the flange 4 for connecting valve to be measured and has the container 5 of height Presentation Function, and the top of container 5 is communicated with atmospheric envelope; Be connected with pipeline below described flange 4, described pipeline is communicated with bottom described container 5, and described pipeline is provided with the second ball valve 2.
The method of testing of above-described embodiment scheme is: by valve installation to be measured and flange 4, and close the second ball valve 2, is filled to liquid level (H) for required numerical value, then opens the second ball valve 2, observe the state of valve to be measured in container 5.
In above-described embodiment scheme, bottom described flange 4 and described container 5, be positioned at same level height, make measurement more simple, accurate.
As the part preferred version of above-described embodiment, described container 5 is the graduated transparent glass tube of tool.
As the improvement of above-described embodiment scheme, also comprise feed tube, described feed tube and described pipeline connection, described feed tube is also provided with water pump 6 and the first ball valve 1, makes the water filling of container 5 controlled.
As the improvement of above-described embodiment scheme, bottom described container 5, be provided with the 3rd ball valve 3, when container 5 water filling is excessive, discharge unnecessary water by the 3rd ball valve 3.
Above the technical scheme that the utility model embodiment provides is described in detail, apply specific case herein to set forth the principle of the utility model embodiment and embodiment, the explanation of above embodiment is only applicable to the principle helping to understand the utility model embodiment; Meanwhile, for one of ordinary skill in the art, according to the utility model embodiment, embodiment and range of application all will change, and in sum, this description should not be construed as restriction of the present utility model.
