Description

Technical Field

[0001] This utility model belongs to the field of pressure regulating valve processing, and in particular relates to a valve plate positioning device for a pressure regulating valve. Background Technology

[0002] A pressure regulating valve is a device that controls fluid pressure by adjusting the valve opening, typically used to maintain stable outlet pressure. The valve plate is a crucial component of the pressure regulating valve, consisting of two discs and a sealing ring. The two discs are connected together by screws and nuts. The initial position of the valve plate is critical; normally closed valves are initially in the closed state, with the valve plate perpendicular to the inner wall of the airflow channel, with a vertical angle deviation not exceeding 0.1°.

[0003] Using conventional tools for installation cannot guarantee that the valve plate position is within the error range, which will cause deviations in the valve test parameters during functional testing. The valve plate position must be readjusted, which is labor-intensive, time-consuming, and inefficient. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a valve plate positioning device for a pressure regulating valve.

[0005] This utility model is achieved through the following technical solution: a valve plate positioning device for a pressure regulating valve, comprising a cylindrical device body, the top of the device body being provided with a receiving cavity and multiple positioning holes for positioning the screws of the valve plate, and the side surface of the device body being provided with positioning steps for positioning the airflow channel of the valve.

[0006] Furthermore, the positioning step is a circular ring structure.

[0007] Furthermore, the positioning step is nested on the side surface of the device body.

[0008] Furthermore, the positioning step is integrally formed on the side surface of the device body.

[0009] Furthermore, the valve plate positioning device also includes a base, on which a lead screw is rotatably mounted, the top of which is connected to the bottom of the device body.

[0010] Furthermore, a handle is provided on the side wall of the lead screw.

[0011] Furthermore, the handle is a ball-handle structure.

[0012] Furthermore, a bearing is provided on the base, and the lead screw is installed in the bearing.

[0013] Compared with the prior art, this utility model has the following advantages and beneficial effects: the valve plate positioning device in this utility model has a simple structure and can improve the installation efficiency and installation quality of the valve plate in the pressure regulating valve.

[0022] like Figures 1 to 2 As shown, this utility model discloses a valve plate positioning device for a pressure regulating valve.

[0023] like Figure 1 and Figure 2 As shown, the valve plate 4 positioning device of the pressure regulating valve includes a cylindrical device body 1. The top of the device body 1 is provided with a receiving cavity 11 and a plurality of positioning holes 12 for positioning the screws of the valve plate 4. The side surface of the device body 1 is provided with positioning steps for positioning the airflow channel 5 of the valve.

[0024] When installing the valve plate 4 and airflow channel 5 of the pressure regulating valve, first align the screws on the valve plate 4 with the positioning hole 12 in the valve plate 4 positioning device, and then fix the valve plate 4 on the valve plate 4 positioning device. At this time, the protruding part of the lower disc in the valve is located in the receiving cavity 11. Then slowly lower the airflow channel 5 of the valve plate 4 until the lower end of the airflow channel 5 contacts the positioning step. This position is the initial position of the valve plate 4. Then, use the valve shaft of the pressure regulating valve to pass through the airflow channel 5 and the valve plate 4.

[0025] In some embodiments of this example, the positioning step is a circular ring structure, and the outer diameter of the positioning step is larger than the inner diameter of the airflow channel 5.

[0026] The positioning step is nested on the side surface of the device body 1, or the positioning step is integrally formed on the side surface of the device body 1.

[0027] In some embodiments of this example, the valve plate 4 positioning device further includes a base 3, on which a lead screw 2 is rotatably mounted. The top of the lead screw 2 is connected to the bottom of the device body 1. When installing the valve plate 4 and the airflow channel 5 of the pressure regulating valve, first align the screws on the valve plate 4 with the positioning holes 12 in the valve plate 4 positioning device, then rotate the lead screw 2, thereby rotating the device body 1 to tighten the screws on the valve plate 4, and then install the airflow channel 5.

[0028] In some embodiments of this example, a handle is provided on the side wall of the lead screw 2 to facilitate rotation of the lead screw 2, for example, the handle is a ball handle structure.

[0029] In some embodiments of this example, a bearing 31 is provided on the base 3, and the lead screw 2 is installed in the bearing 31. For example, the lead screw 2 passes through the bearing 31 from bottom to top, the lower end of the lead screw 2 is engaged with a nut for limiting, and the upper end of the lead screw 2 is connected to the bottom of the device body 1.

[0030] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
