Description

Technical Field

[0001] This utility model relates to the field of one-way valve technology, and in particular to a one-way valve control device. Background Technology

[0002] One-way valves, with their simple structure and high reliability, are widely used in various fields such as petrochemicals, water supply and drainage, HVAC, and machinery manufacturing. In water supply and drainage systems, water pipe one-way valves are one of the key components, mainly installed in various water pipes (such as tap water pipes, hot water circulation pipes, and water pump outlet pipes), playing an important role in preventing backflow of water in the pipes. For example, in the secondary water supply system of residential buildings, water pipe one-way valves can prevent water in the pipe network from flowing back into the water pump and water source tank when the water pump stops working, preventing water pollution and water pump damage. However, existing water pipe one-way valves rely only on simple springs or buckles for limiting the position. Under long-term water flow impact and pressure fluctuation conditions, the fixed structure is prone to loosening and displacement, causing the valve core to fail to accurately reset, resulting in water leakage or backflow, reducing the working reliability of the one-way valve. During maintenance, the connection between the valve core and the valve body is complex, and there is a lack of convenient positioning and disassembly mechanisms. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies. Existing water pipe check valves rely solely on simple springs or clips for limiting movement. Under long-term water flow impact and pressure fluctuations, the fixed structure is prone to loosening and displacement, causing the valve core to fail to accurately reset, resulting in water leakage or reverse flow, reducing the reliability of the check valve. Furthermore, during maintenance, the connection between the valve core and the valve body is complex, and there is a lack of convenient positioning and disassembly mechanisms. This invention provides a check valve control device.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] like Figure 1-4 As shown, this utility model provides a technical solution: a one-way valve control device, including a valve body 1, a valve core 2 disposed inside the valve body 1, a fixing structure 3 disposed on the top of the valve core 2, a flow tube 11 in the valve body 1, a control tube fixedly connected to the top of the flow tube 11, a support block 12 fixedly connected to the inner wall of the control tube, a support port opened on one side of the support block 12, a movable valve 21 in the valve core 2, a rotating shaft 22 fixedly connected to the top of the movable valve 21, a connecting block 23 rotatably connected to the outer surface of the rotating shaft 22, the outer surface of the connecting block 23 slidingly connected to the inner wall of the support port, and the connecting block 23... The outer surface of the fixed structure 3 is provided with a connecting groove, and the inner wall of the connecting groove is provided with a positioning hole 24. The fixed structure 3 includes a positioning insert plate 31. The outer surface of the positioning insert plate 31 is slidably connected to the inner wall of the support port. The bottom of the positioning insert plate 31 is engaged with the inner wall of the connecting groove. The bottom of the positioning insert plate 31 is provided with a moving groove. A sliding opening 33 is provided on one side of the moving groove. A limiting block 34 is slidably connected to the inner wall of the sliding opening 33. The outer surface of the limiting block 34 is engaged with the inner wall of the sliding opening 33. A positioning plate 36 is fixedly connected to one side of the limiting block 34. The outer surface of the positioning plate 36 is engaged with the inner wall of the positioning hole 24.

[0027] In this embodiment, by setting a support block 12 and opening a specific support port on its inner side, the positioning insert 31 can be stably locked in the internal space of the support block 12 with the help of this support port. Furthermore, at the lower end of the support port, a movable port is provided to engage with the connecting block 23, which allows the connecting block 23 to be easily inserted laterally into the position set at the bottom of the support block 12. At this time, the positioning insert 31 will be locked in the upper part of the connecting block 23, and its vertical movement will be restricted. In addition, a positioning hole 24 and a positioning plate 36 are provided to facilitate the positioning of the positioning insert 31 and at the same time restrict the forward movement of the connecting block 23. The limiting block 34 and the sliding port 33 are also provided to prevent the positioning plate 36 from disengaging from the positioning insert 31 and to allow it to move only in the movable slot. When the cap at the top of the one-way valve is screwed on, the position of the connecting block 23 can be further restricted more precisely and stably.

[0028] Example 2

[0029] like Figure 1-4 As shown, the top of the positioning plate 31 has an insertion hole, and the inner wall of the insertion hole is slidably connected to a top rod 32. The bottom of the top rod 32 is fixedly connected to a pressing head 35. One side of the pressing head 35 is slidably connected to one end of the positioning plate 36. The insertion hole and the moving groove are arranged through each other.

[0030] In this embodiment, the push rod 32 and the extrusion head 35 can push the positioning plate 36, which was originally located in the moving groove, into the positioning hole 24 when you move it down, so as to finally fix the upper position of the valve core 2.

[0031] In addition, during maintenance, simply move the limit block 34 in the opposite direction to push the push rod 32 out of the insertion hole to easily remove the push rod 32, and then remove other components. This ensures the installation stability of the valve core 2 while making it easier to disassemble and maintain.

[0032] Working principle:

[0033] like Figure 1-4As shown, during actual installation, the movable valve 21 is first inserted into the flow pipe 11 from the middle part of the pipe opening. Then, the connecting block 23 is inserted horizontally along the inner wall of the lower end of the support port, so that the connecting groove is aligned with the bottom of the positioning plate 31. Then, the positioning plate 31 is inserted into the support port from top to bottom, and its bottom is locked into the connecting groove to achieve initial positioning. Next, the top rod 32 is pressed, which drives the extrusion head 35 to move down. The inclined surface of the extrusion head 35 pushes the positioning plate 36 to slide along the moving groove. The limiting block 34 moves synchronously in the sliding port 33 until the positioning plate 36 is inserted into the positioning hole 24, thus completing the fixing of the valve core 2 and the valve body 1. During maintenance, it is only necessary to move the limiting block 34 in the opposite direction and extrude the top rod 32 in the opposite direction to push it out of the insertion hole, so that the top rod 32 can be easily removed. Then, other components can be removed. This ensures the installation stability of the valve core 2 while making it easier to disassemble and maintain.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
