Description

Technical Field

[0001] This utility model belongs to the field of valve technology, specifically a valve with pressure regulation function. Background Technology

[0002] Valves are control components in fluid transport systems, with functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. They can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media.

[0003] Meanwhile, the publicly disclosed (announcement) number CN218326257U2 is a self-regulating valve with automatic pressure adjustment, including a housing, a through hole, a motor and a rotating block. A connecting block is provided at the upper end of the housing, and a motor is provided at the upper end of the connecting block. A through hole is provided inside the housing, and a rotating block is provided inside the through hole. The rotating block is adapted to the motor, and pressure sensors are provided on both sides of the rotating block.

[0004] The aforementioned type of automatic pressure regulating valve relies solely on a single point of pressure detection at the outlet end during use, which cannot fully reflect the pressure distribution within the pipeline. It is prone to adjustment deviations due to sudden changes in inlet pressure, and it lacks a pressure buffer structure, resulting in large fluctuations in fluid pressure during adjustment, which can easily impact downstream equipment.

[0005] Therefore, a valve with pressure regulation function is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background section, this invention provides a valve with pressure regulation function, which has the advantages of comprehensive pressure detection and small pressure fluctuation.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a valve with pressure regulating function, comprising a valve body device, the valve body device including a valve body shell, a pressure relief component fixedly provided on the left side of the valve body shell, the pressure relief component including a pressure relief shell, a blocking ball slidably provided inside the pressure relief shell, a limiting block fixedly provided on the right side of the blocking ball, a telescopic rod fixedly provided on the rear side of the blocking ball, a telescopic spring fixedly provided on the outer side of the telescopic rod, a fixing plate fixedly provided on the rear side of the telescopic rod, a stud spirally provided inside the fixing plate, a slider fixedly provided at the bottom of the fixing plate, and a hand crank fixedly provided on the rear side of the stud.

[0008] Preferably, the front side of the pressure relief shell is provided with six pressure relief holes, which are slidably connected to the limiting block. The bottom side of the inner side of the pressure relief shell is provided with a sliding groove, which is slidably connected to the slider.

[0009] By adopting the above technical solutions, the pressure relief area is increased, thus preventing pressure buildup.

[0010] Preferably, the valve body housing is provided with a guide plate inside, and there are seven guide plates, which are evenly fixed on the inner wall of the valve body housing.

[0011] By adopting the above technical solution, the impact of fluid on the inner wall of the valve body and other components is reduced.

[0012] Preferably, a valve assembly is provided on the top of the valve body shell, the valve assembly includes a motor, a connecting column is fixedly provided at the end of the motor's main shaft, a valve plate is fixedly provided inside the connecting column, and the valve plate is in contact with the inner wall of the valve body shell.

[0013] By employing the above technical solution, fluid flow is blocked, thereby achieving pressure control.

[0014] Preferably, an air inlet is provided on the front side of the valve body shell, and an air outlet is provided on the rear side of the valve body shell, and a fixing flange is fixedly provided on the outer side of both the air inlet and the air outlet.

[0015] By adopting the above technical solution, the connection strength is guaranteed, and the interface detachment caused by fluid pressure is avoided.

[0016] Preferably, pressure sensors are spirally provided at the top of both the air inlet and the air outlet, and the detection ends of the pressure sensors extend into the valve body housing.

[0017] By adopting the above technical solution, pressure can be monitored in real time.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This utility model allows for flexible setting of the valve's pressure relief threshold by adjusting the spring force through a hand crank and stud, adapting to pressure requirements in different scenarios. The linkage design of the blocking ball, spring, and fixing plate enables automatic triggering of the pressure relief action without continuous manual intervention, thus improving safety and convenience.

[0020] 2. This utility model achieves comprehensive monitoring and precise regulation of fluid pressure through dual pressure sensors at the inlet and outlet. When the inlet and outlet pressures suddenly rise, drop, or exceed the safe range, the sensors can provide feedback signals to promptly remind the user to take action, preventing damage to pipelines or valves due to abnormal pressure, thus improving safety. The baffle plate effectively reduces pressure fluctuations and protects downstream equipment. Attached Figure Description

[0027] 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.

[0028] The following describes an embodiment of this utility model based on its overall structure.

[0029] like Figures 1 to 5 As shown, this utility model provides a valve with pressure regulation function, including a valve body device 1. The valve body device 1 includes a valve body shell 101. A pressure relief component 2 is fixedly provided on the left side of the valve body shell 101. The pressure relief component 2 includes a pressure relief shell 201. A blocking ball 203 is slidably provided inside the pressure relief shell 201 to block or open the pressure relief channel and control whether pressure is released. A limiting block 204 is fixedly provided on the right side of the blocking ball 203 to limit the sliding range of the blocking ball 203 and prevent it from deviating or deviating from the preset trajectory. A telescopic rod 205 is fixedly provided on the rear side of the blocking ball 203. A telescopic spring 206 is fixedly provided on the outer side of the telescopic rod 205 to form a pressure threshold trigger. A fixing plate 207 is fixedly provided on the rear side of the telescopic rod 205. A stud 209 is spirally provided inside the fixing plate 207. A slider 208 is fixedly provided at the bottom of the fixing plate 207 to assist the fixing plate 207 in stable movement. A hand crank 211 is fixedly provided on the rear side of the stud 209 to flexibly set the pressure relief threshold of the valve.

[0030] In this embodiment, six pressure relief holes 202 are evenly provided on the front side of the pressure relief shell 201. Fluid can be discharged through the pressure relief holes 202. The pressure relief holes 202 are slidably connected to the limiting block 204. A sliding groove 210 is provided on the inner bottom side of the pressure relief shell 201. The sliding groove 210 is slidably connected to the slider 208. The slider 208 can move stably within the sliding groove 210.

[0031] The valve body housing 101 has a flow guide plate 7 inside. There are seven flow guide plates 7, which are evenly fixed on the inner wall of the valve body housing 101 to guide the flow direction of the fluid.

[0032] The valve assembly 3 is provided on the top of the valve body housing 101. The valve assembly 3 includes a motor 301. A connecting column 302 is fixedly provided at the end of the main shaft of the motor 301. A valve plate 303 is fixedly provided inside the connecting column 302. The valve plate 303 is in contact with the inner wall of the valve body housing 101. When the motor 301 drives the connecting column 302 to rotate, the valve plate 303 rotates accordingly to achieve closing or opening.

[0033] The valve body housing 101 has an air inlet 5 on the front side and an air outlet 6 on the rear side, which are channels for fluid to enter and exit the valve. Both the air inlet 5 and the air outlet 6 are fixedly provided with fixed flanges 8 on the outside to achieve fixed connection with the pipeline.

[0034] Pressure sensors 4 are spirally installed on the top of both the air inlet 5 and the air outlet 6. The detection end of the pressure sensor 4 extends into the valve body housing 101 to simultaneously obtain the fluid pressure at the valve inlet and outlet.

[0035] The motor is existing technology and will not be described in detail. Additionally, this invention includes a pressure sensor, which is not a key technical feature of this patent and will not be described in detail either. The wiring diagram of the motor in this invention is common knowledge in the field, and its working principle is already known technology. The appropriate model should be selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0036] The working principle and process of a valve with pressure regulating function:

[0037] When the motor 301 of valve assembly 3 is not started, the valve plate 303 is in contact with the inner wall of valve body shell 101, blocking the connection between the air inlet 5 and the air outlet 6, and the fluid cannot pass through the valve. When fluid needs to pass through, the motor 301 starts, and its main shaft drives the connecting column 302 to rotate, which in turn drives the valve plate 303 to rotate synchronously. At this time, a flow channel is formed between the air inlet 5 and the air outlet 6, and the fluid enters the interior of valve body shell 101 from the air inlet 5. When the fluid flows in the valve body shell 101, seven evenly distributed guide plates 7 guide the fluid to flow smoothly along a preset trajectory, reducing turbulence and impact on the inner wall. The pressure sensor 4 at the top of the air inlet 5 and the air outlet 6 monitors the fluid pressure in real time and controls the pressure by driving the valve plate 303.

[0038] When the internal pressure of the valve body exceeds the preset threshold, the fluid pressure pushes the blocking ball 203 of the pressure relief assembly 2, overcoming the elastic force of the telescopic spring 206, causing the blocking ball 203 to slide backward. At this time, the pressure relief hole 202 on the front side of the pressure relief housing 201 is opened, and excess fluid is discharged through the pressure relief hole 202, reducing the internal pressure of the valve body. When the pressure drops below the threshold, the elastic force of the telescopic spring 206 pushes the blocking ball 203 forward to reset, re-sealing the pressure relief hole 202 and stopping the pressure relief. If it is necessary to adjust the pressure relief threshold, the user can turn the hand crank 211 to drive the stud 209 to rotate, pushing the fixed plate 207 to move back and forth, so as to realize the flexible adjustment of the pressure relief threshold.
