Description

Technical Field

[0001] This utility model relates to the field of regulating valve technology, and in particular to a water supply regulating valve for water pipes. Background Technology

[0002] In water pipeline transportation systems, the water supply regulating valve is the core component for controlling water flow interruption and pressure regulation. It is widely used in residential water supply, industrial fluid transportation and other scenarios. Most existing water supply regulating valves adopt a rigid sealing structure. The fit between the sealing valve disc and the flow channel depends on a fixed mechanical structure. When the water flow pressure fluctuates, problems such as poor sealing or intermittent water flow may occur, affecting the stability of water use.

[0003] Meanwhile, traditional control valves mostly provide rigid pressure regulation, which cannot adaptively buffer changes in water pressure. This not only limits the regulation accuracy but may also lead to accelerated wear of valve components due to sudden changes in water pressure, shortening their service life. In addition, some control valves lack effective anti-leakage structures at their threaded connections, allowing water to easily seep into the thread gaps, causing thread corrosion and jamming, affecting the smoothness of regulation operation, and in severe cases, causing valve failure.

[0004] Therefore, it is necessary to provide a new water supply regulating valve for water pipes to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a water pipe water supply regulating valve.

[0006] The water supply regulating valve provided by this utility model includes a valve body, in which a flow ring seat is fixedly fitted, and a flow channel is provided in the middle of the flow ring seat. A sealing valve disc for sealing the flow ring seat is installed in the valve body.

[0007] The valve body is equipped with an adjustment component for adjusting the water flow pressure, and the adjustment component includes a threaded adjustment rod and a connecting rod. The threaded adjustment rod is inserted into a threaded through hole opened at the tail of the valve body and is threadedly connected to the threaded through hole. One end of the connecting rod is fixedly connected to the sealing valve disc, and the connecting rod is elastically connected to the threaded adjustment rod.

[0008] The threaded adjusting rod has a piston disc fixedly sleeved on its head, which is slidably connected to the inner cavity of the valve body.

[0009] Preferably, the other end of the connecting rod is inserted into the guide cavity of the threaded adjusting rod and slidably connected to the guide cavity. A retaining plate is fixedly sleeved on the connecting rod, and a spring is installed between the retaining plate and the piston plate.

[0010] Preferably, rotating rings are fixedly installed at both ends of the spring, with the rotating ring at one end of the spring rotatably connected to the abutment disc and the rotating ring at the other end of the spring rotatably connected to the piston disc.

[0011] Preferably, a knob is fixedly installed on the outer end of the threaded adjusting rod.

[0012] Preferably, a rotatably connected mounting ring is fitted inside the annular groove on the sealing valve disc, and multiple annularly distributed flaps are fixedly fitted into the outer ring wall of the mounting ring.

[0013] Preferably, the valve body has a docking valve port at its front end, a docking valve pipe is fixedly installed in the middle of the valve body, and the flow ring seat is disposed between the docking valve pipe and the docking valve port.

[0014] Compared with related technologies, the water supply regulating valve for water pipes provided by this utility model has the following beneficial effects:

[0015] In this invention, the adjusting component is elastically connected to the threaded adjusting rod via a central connecting rod. The elastic force of the spring drives the sealing valve disc to stably seal the flow ring seat. When the water pressure reaches the set threshold, the water flow pushes the sealing valve disc to move and achieve flow, effectively avoiding the problem of intermittent water flow and adapting to the usage requirements of different water pressure scenarios. When the sealing valve disc no longer seals the flow channel of the flow ring seat, the water flow quickly impacts the folded plate. Therefore, the stirring structure formed by the mounting ring and the folded plate stirs the flowing water. The turbulence and secondary flow generated by the stirring structure can play a "self-cleaning" role on the inner wall of the valve body, rolling up and carrying away particles, effectively preventing blockage and scale buildup.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0021] Please see Figures 1 to 2 The present invention provides a water pipe water supply regulating valve, which includes a valve body 1, a sealing valve disc 3, and a regulating component 4.

[0022] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 A flow ring seat 2 is fixedly fitted inside the valve body 1, and a flow channel is provided in the middle of the flow ring seat 2. A sealing valve disc 3 for sealing the flow ring seat 2 is installed inside the valve body 1. A docking valve port 11 is provided at the front end of the valve body 1. A docking valve pipe 12 is fixedly installed in the middle of the valve body 1. The flow ring seat 2 is located between the docking valve pipe 12 and the docking valve port 11.

[0023] The valve body 1 is equipped with a regulating component 4 for adjusting the water flow pressure. The regulating component 4 includes a threaded adjusting rod 41 and a connecting rod 42. The threaded adjusting rod 41 is inserted into a threaded through hole 1a at the tail of the valve body 1 and is threadedly connected to the threaded through hole 1a. A piston disc 43, which slides within the inner cavity of the valve body 1, is fixedly sleeved on the head of the threaded adjusting rod 41. One end of the connecting rod 42 is fixedly connected to the sealing valve disc 3, and the connecting rod 42 is elastically connected to the threaded adjusting rod 41. Specifically…

[0024] The other end of the connecting rod 42 is inserted into the guide cavity 41a of the threaded adjusting rod 41 and is slidably connected to the guide cavity 41a. A mating plate 44 is fixedly sleeved on the connecting rod 42, and a spring 45 is installed between the mating plate 44 and the piston plate 43. Rotating rings are fixedly installed at both ends of the spring 45. The rotating ring at one end of the spring 45 is rotatably connected to the mating plate 44, and the rotating ring at the other end of the spring 45 is rotatably connected to the piston plate 43. A knob 46 is fixedly installed on the outer rod head of the threaded adjusting rod 41.

[0025] It should be noted that: the docking valve port 11 is used as the water inlet and connected to the pipeline, while the docking valve pipe 12 is used as the drain port and connected to another pipeline. When water is transported, the water flows into the valve body 1. At this time, under the action of the spring 45, the sealing valve disc 3 is driven to seal the flow channel of the flow ring seat 2. When the water pressure increases, it pushes the sealing valve disc 3 away from the flow ring seat 2. At this time, the connecting rod 42 slides along the guide cavity 41a and drives the spring 45 to compress. Therefore, the flow channel in the flow ring seat 2 is opened, thus forming a flow path. This ensures that the water flow will not be interrupted after the water passes through the valve body 1.

[0026] When the knob 46 is turned to drive the threaded adjusting rod 41 to screw along the threaded through hole 1a, the piston disc 43 moves toward the flow ring seat 2, so the spring 45 is compressed, so that a stronger liquid is needed to drive the sealing valve disc 3 to stop sealing the flow channel of the flow ring seat 2.

[0027] The piston disc 43 can effectively prevent water from flowing to the threaded through hole 1a at the tail of the valve body 1, thus eliminating the potential for water leakage at the threaded through hole 1a.

[0028] Therefore, in this application, the adjusting component 4 is elastically connected to the threaded adjusting rod 41 via the central connecting rod 42. The elastic force of the spring 45 can drive the sealing valve disc 3 to stably seal the flow ring seat 2. When the water pressure reaches the set threshold, the water flow pushes the sealing valve disc 3 to move and achieve flow, effectively avoiding the problem of intermittent water flow and adapting to the usage requirements of different water pressure scenarios. The knob 46 can drive the threaded adjusting rod 41 to rotate in or out along the threaded through hole 1a, thereby adjusting the initial compression of the spring 45 and adjusting the water pressure required to open the sealing valve disc 3, meeting the pressure adjustment requirements under different scenarios. The operation is simple and intuitive. The piston disc 43 is slidably connected to the inner cavity of the valve body 1, which can block the water from flowing to the threaded through hole 1a at the tail of the valve body 1, avoiding corrosion and jamming of the threaded part. At the same time, the two ends of the spring 45 are rotatably connected to the abutment disc 44 and the piston disc 43 through the rotating ring, reducing mechanical wear during the adjustment process and extending the overall service life of the valve.

[0029] In addition, to eliminate the potential risk of spring 45 rusting and losing its elasticity due to contact with water, spring 45 is made of stainless steel or titanium alloy to improve corrosion resistance. At the same time, a polytetrafluoroethylene (PTFE) coating is applied to the surface of spring 45 to enhance its rust prevention ability.

[0030] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 An annular groove on the sealing valve disc 3 is fitted with a rotating mounting ring 5, and multiple annularly distributed flaps 6 are fixedly fitted into the outer ring wall of the mounting ring 5.

[0031] It should be noted that when the sealing valve disc 3 no longer seals the flow channel of the flow ring seat 2, the water flow rapidly impacts the folding plate 6. Therefore, the stirring structure formed by the mounting ring 5 and the folding plate 6 stirs the flowing water. The turbulence and secondary flow generated by the stirring structure can play a "self-cleaning" role on the inner wall of the valve body 1, rolling up and carrying away particles, effectively preventing blockage and scale buildup.

[0032] Among them, the folding piece 6 is made of high-strength stainless steel, which improves its impact resistance and fatigue resistance, making it suitable for high water pressure conditions.

[0033] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
