[0027] The embodiments of the utility model are described below through specific examples, and other advantages and effects of the utility model can be easily understood by those skilled in the art according to the disclosure of the specification. The utility model can also be implemented or applied through different specific embodiments, and various modifications or changes can be made to the details in the specification based on different viewpoints and applications without departing from the spirit of the utility model.

[0028] Please refer to Figure 1It is to be noted that the diagrams provided in the present embodiment only schematically illustrate the basic concept of the present application, and only show the components related to the present application in the diagrams, rather than being drawn according to the number, shape and size of the components in actual implementation. The shape, number and proportion of each component in implementation can be arbitrarily changed, and the component layout pattern can be more complex. The structure, proportion, size, etc. shown in the drawings of the present specification are only used to cooperate with the content disclosed in the specification, so as to be understood and read by those skilled in the art, and do not define the limiting conditions for the implementation of the present application, so they do not have substantial technical significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the functions and purposes that can be achieved by the present application, should still fall within the scope of the technical content disclosed by the present application. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" in the present specification are only for the convenience of clear description, and are not used to limit the scope of the present application. The change or adjustment of the relative relationship, without substantially changing the technical content, is also considered as the scope of the present application.

[0029] Please refer to Figure 1 The present application provides a high-pressure valve water pressure device, comprising:

[0030] A valve body 1, the liquid inlet end and the liquid outlet end of the valve body 1 are both inclined.

[0031] A water pressure unit 2, one water pressure unit 2 is arranged at the liquid inlet end and the liquid outlet end respectively.

[0032] The water pressure unit 2 comprises a bottom plate 201 and a connecting cylinder 202, the connecting cylinder 202 is arranged on the bottom plate 201, the bottom plate 201 is provided with a through hole, and the inner wall of the connecting cylinder 202 is inclined, and the inner wall of the connecting cylinder 202 is used to fit the outer wall of the liquid inlet end and the liquid outlet end of the valve body 1.

[0033] It should also be noted that the conventional valve body wrapping test uses a radial sealing method to perform a valve pressure test on the valve flow passage inner hole of the valve pressure device. This method has high requirements for the inner hole size and surface roughness. The present application sets the sealing position on the outer wall of the liquid inlet end and the liquid outlet end of the valve body 1, especially the inclined part of the outer wall, thereby avoiding the need for direct processing and sealing of the flow passage inner hole.

[0034] For example, a plurality of sealing rings 101 are arranged between the inner wall of the connecting cylinder 202 and the outer wall of the valve body 1.

[0035] It should be noted that there may be slight dimensional tolerances in the manufacturing process of the valve body and the tooling. The arrangement of multiple sealing rings can compensate for these tolerances to some extent, ensuring a tight fit between the tooling and the valve body, thereby improving the sealing effect. Due to the arrangement of multiple sealing rings, the tooling can withstand higher test pressure. In the valve pressure test, the high-pressure environment puts higher requirements on the sealing performance, and the design of multiple sealing rings can better cope with this challenge. The arrangement of multiple sealing rings 101 can more effectively prevent liquid leakage during testing, thereby improving the accuracy and safety of the test. Even if one of the sealing rings is slightly damaged or worn, the other sealing rings can still provide effective sealing to ensure normal testing.

[0036] Illustratively, the bottom plate 201 and the connecting cylinder 202 are both made of metal.

[0037] It should be noted that metal has high strength and rigidity, which can ensure that the tooling does not deform or break during use, thereby maintaining its stability and reliability. Since the valve pressure test needs to withstand high pressure, metal can provide good pressure-bearing capacity to ensure that the tooling does not leak or fail under high pressure. Metal has good machinability and weldability, making it easy to be cast, forged, machined, etc. into the required shape and size.

[0038] Illustratively, the sealing ring 101 is a rubber sealing ring.

[0039] It should be noted that rubber sealing rings have good elasticity and sealing performance, which can effectively fill the small gap between the inner wall of the connecting cylinder 202 and the outer wall of the valve body 1, preventing liquid leakage during testing.

[0040] Further explanation is that for environments that need to withstand extremely high temperature or pressure, metal sealing rings can be used, which have high strength and rigidity and can maintain their integrity in harsh environments, or plastic sealing rings can be used, which have lighter weight, good chemical resistance and lower cost.

[0041] Illustratively, the bottom plate 201 and the connecting cylinder 202 are integrally formed.

[0042] It should be noted that the design of integral forming makes there be no joints or connection points between the bottom plate 201 and the connecting cylinder 202, thereby enhancing the structural integrity of the tooling. This integrity helps to improve the strength and rigidity of the tooling, enabling it to withstand higher test pressure. The design of integral forming reduces the risk of leakage due to improper joints or connection points. The smooth transition between the inner wall of the connecting cylinder 202 and the bottom plate 201 helps to ensure that the sealing ring 101 can be uniformly stressed, thereby improving the sealing effect.

[0043] Exemplarily, a plurality of hoisting holes 3 are arranged on the outer wall of the bottom plate 201, and the hoisting holes 3 are used for hoisting connection before the high-pressure valve water pressure device is pressed by the press on both sides of the valve body.

[0044] Exemplarily, a plurality of annular grooves are arranged on the inner wall of the connecting barrel 202, and the plurality of annular grooves correspond to the plurality of sealing rings one by one, and the sealing rings are arranged in the corresponding annular grooves.

[0045] It also needs to be explained that the purpose of arranging the annular grooves is to enable the sealing rings to be clamped in the corresponding annular grooves, so as not to cause displacement or loosening of the sealing rings, and at the same time, 80% of the sealing rings are clamped in the annular grooves, and 20% of the sealing rings protrude from the annular grooves, so as to ensure sufficient compression amount of the sealing rings to achieve sealing effect.

[0046] Exemplarily, all the annular grooves are arranged equidistantly.

[0047] It also needs to be explained that the equidistant arrangement of the annular grooves can maximize the provision of multi-layer sealing, and further improve the sealing effect.

[0048] Exemplarily, the inner diameter of the liquid inlet end is smaller than the inner diameter of the connecting barrel.

[0049] The purpose of such arrangement is to ensure that the water pressure unit 2 can adapt to as many specifications of the liquid inlet end of the valve body 1 as possible, and improve the adaptation range of the water pressure unit 2.

[0050] Exemplarily, the inner diameter of the liquid outlet end is smaller than the inner diameter of the connecting barrel.

[0051] The purpose of such arrangement is to ensure that the water pressure unit 2 can adapt to as many specifications of the liquid outlet end of the valve body 1 as possible, and improve the adaptation range of the water pressure unit 2.

[0052] In summary, the high-pressure valve water pressure device of the utility model avoids the need for directly processing and sealing the inner hole of the flow channel, reduces the processing cost of the valve body and the tooling, and improves the adaptability of the sealing plug.

[0053] The above embodiments only exemplarily illustrate the principle and effect of the utility model, and are not used for limiting the utility model. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and category of the utility model. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the utility model should be covered by the claims of the utility model.
