DETAILED IMPLEMENTATION MANNER

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figure 1 、 Figure 3 and Figure 5, an embodiment provided by the present utility model: a valve pressure detection device, including a workbench 1. At the four corners of the bottom wall of the workbench 1, columns 3 are fixedly connected. Between adjacent ones of the multiple columns 3, a carrier plate 4 is fixedly connected. At the left end of the top wall of the carrier plate 4, a water tank 5 is fixedly connected. On the right side of the inner wall of the water tank 5, a water pipe 7 is communicated. In the middle of the water pipe 7, a water pump 6 is fixedly installed. The bottom end of the water pump 6 is fixedly connected to the inner bottom wall of the water tank 5. The right end of the water pipe 7 is communicated with the left side of the inner wall of the workbench 1. At the right side of the top wall of the carrier plate 4, a supercharger 8 is fixedly connected. At the left end of the supercharger 8, an air duct 9 is communicated. At the front end of the air duct 9, a shunt pipe 10 is communicated. At equal intervals on the top wall of the shunt pipe 10, multiple branch pipes 11 are communicated. The multiple branch pipes 11 all penetrate through the inner bottom wall of the workbench 1. At the top ends of the multiple branch pipes 11, fixed valves 12 are communicated. On the top walls of the multiple fixed valves 12, locking grooves 13 are opened. At the rear side of the inner wall of the workbench 1, a high-pressure fixing device 2 is provided;

[0033] Specifically, the four sides of the bottom of the workbench 1 are supported by four columns 3, which can ensure the stability and load-bearing capacity of the overall structure of the workbench 1. The carrier plate 4 at the bottom provides the installation positions for the water tank 5 and the supercharger 8. During the detection process, the water tank 5 is connected to the water pump 6 through the water pipe 7 to form a closed water circulation system. After the water pump 6 is started, the water in the water tank 5 will be pumped into the workbench 1. At the same time, the supercharger 8 provides a pressure source through the air duct 9 and the shunt pipe 10. The multiple branch pipes 11 on the shunt pipe 10 ensure that the pressure can be evenly distributed to each fixed valve 12. The locking grooves 13 on the top walls of the fixed valves 12 are used to install the valves to be tested. When the supercharger 8 starts to work, the gas pressure is transmitted to the fixed valves 12 through the branch pipes 11 and then applied to the valves to be tested. By adjusting the output pressure of the supercharger 8, different working conditions can be simulated. Since the water in the water tank 5 is pumped into the workbench 1 by the water pump 6 and all the valves to be tested are submerged, the sealing performance and pressure resistance of the valves can be comprehensively tested by observing the bubbles on the water surface and the pressure value of the supercharger 8 in real time, greatly saving the detection time and improving the detection efficiency.

[0034] Refer to Figure 2 , Figure 4 and Figure 5 , the high-pressure fixing device 2 includes multiple fixing brackets 201. At the top ends of the multiple fixing brackets 201, fixing plates 202 are fixedly connected. On the bottom wall of the fixing plate 202, two hydraulic cylinders 203 are fixedly installed. At the bottom ends of the two hydraulic cylinders 203, hydraulic plates 204 are fixedly connected. On the front side of the hydraulic plate 204, multiple fixing grooves 205 are opened at equal intervals. Around the top walls of the multiple fixed valves 12, multiple fixing bolts 206 are opened at equal intervals;

[0035] Specifically, the top end of the fixing bracket 201 inside the high-pressure fixing device 2 is fixedly connected to the fixing plate 202. Two hydraulic cylinders 203 are installed at the bottom of the fixing plate 202. By controlling the expansion and contraction of the hydraulic cylinders 203, the fixing force can be precisely adjusted. The bottom end of the hydraulic cylinder 203 is connected to the hydraulic plate 204. A plurality of fixing grooves 205 are provided on the front side of the hydraulic plate 204. When the hydraulic cylinder 203 is activated, the hydraulic plate 204 will move downward, contact the top wall of the fixing valve 12, and be tightly combined with the fixing bolts 206 around the top wall of the fixing valve 12 through the fixing grooves 205 to form a stable fixing structure. During the ultra-high pressure detection process, the valve will be subjected to a strong pressure generated by the booster 8. Through the strong thrust provided by the hydraulic cylinder 203, the hydraulic plate 204 is tightly pressed on the fixing valve 12 to ensure that the valve will not move or break due to excessive pressure, realizing the firm fixing of the valve and ensuring the smooth progress of the ultra-high pressure detection process.

[0036] Refer to Figure 2 and Figure 3 , on the left side of the top wall of the workbench 1, a conveyor belt 14 is fixedly installed. In the middle of the left side of the top wall of the workbench 1, a support plate 15 is fixedly connected. The support plate 15 penetrates through the inner wall of the conveyor belt 14; in the upper middle part of the rear side of the water tank 5, a water injection pipe 16 is communicated. The top end of the water injection pipe 16 is rotatably connected to a water injection door 17; at the bottom end of the rear side of the water tank 5, a drain pipe 18 is communicated. A drain valve 19 is fixedly installed in the middle of the drain pipe 18;

[0037] Specifically, the conveyor belt 14 is used to automatically and continuously move the valve to be detected during the detection process, which can greatly improve the detection efficiency and reduce manual operation. The support plate 15 inside it is used to support the conveyor belt 14 to prevent deviation and sag. The water injection pipe 16 is used to inject water into the water tank 5, and the water injection door 17 can close the water injection pipe 16 to prevent external dust and impurities from entering the water tank 5 and causing pollution. The drain pipe 18 is used to drain water from the water tank 5, and the drain valve 19 can control the speed and amount of drainage so as to drain the water when the detection is completed or when the water tank 5 needs to be cleaned.

[0038] Refer to Figure 2 , on the front side of the workbench 1, a control console 20 is fixedly connected. A plurality of control buttons 21 are fixedly installed on the top of the control console 20; on the front side of the water tank 5, a liquid level gauge 22 is fixedly connected. A scale pointer 23 is arranged on the front side of the liquid level gauge 22; at the four corners of the top wall of the workbench 1, anti-collision corners 24 are fixedly connected. A plurality of anti-collision corners 24 are all made of rubber material;

[0039] Specifically, the control console 20 is the operation area of the device, responsible for receiving and sending various instructions. The control buttons 21 on the top can perform switch operations on the hydraulic column 203, water pump 6, and supercharger 8. The liquid level gauge 22 is used to display the water level in the water tank 5. By observing the scale pointer 23, it is possible to know whether the water volume in the water tank 5 is sufficient, so as to replenish the water source in a timely manner when needed. The anti-collision angle 24 is used to prevent the device from causing harm to the operator during operation. The rubber material increases the elasticity and wear resistance of the anti-collision angle 24.

[0040] Working principle: The four sides of the bottom of the workbench 1 are supported by four columns 3, which can ensure the stability and load-bearing capacity of the overall structure of the workbench 1. The carrier plate 4 at the bottom provides the installation positions for the water tank 5 and the supercharger 8. During the detection process, the water tank 5 is connected to the water pump 6 through a water pipe 7 to form a closed water circulation system. After the water pump 6 is started, it will pump the water in the water tank 5 into the workbench 1. At the same time, the supercharger 8 provides a pressure source through the air duct 9 and the shunt pipe 10. Multiple branch pipes 11 on the shunt pipe 10 ensure that the pressure can be evenly distributed to each fixed valve 12. The locking groove 13 on the top wall of the fixed valve 12 is used to install the valve to be tested. When the supercharger 8 starts to work, the gas pressure is transmitted to the fixed valve 12 through the branch pipe 11, and then applied to the valve to be tested. By adjusting the output pressure of the supercharger 8, different working conditions can be simulated. Since the water in the water tank 5 is pumped into the workbench 1 by the water pump 6 and all the valves to be tested are submerged, the sealing performance and pressure resistance of the valves can be comprehensively tested by observing the bubbles on the water surface and the pressure value of the supercharger 8 in real time. The model of the water pump 6 is Grundfos MQ3-35, and the model of the supercharger 8 is TVS R1320.

[0041] And the top end of the fixed bracket 201 in the high-pressure fixing device 2 is fixedly connected to the fixing plate 202. Two hydraulic columns 203 are installed at the bottom of the fixing plate 202. By controlling the telescopic movement of the hydraulic columns 203, the fixing force can be precisely adjusted. The bottom end of the hydraulic column 203 is connected to the hydraulic plate 204. A plurality of fixing grooves 205 are provided on the front side of the hydraulic plate 204. When the hydraulic column 203 is started, the hydraulic plate 204 will move downward, contact the top wall of the fixed valve 12, and be tightly combined with the fixing bolts 206 around the top wall of the fixed valve 12 through the fixing grooves 205 to form a stable fixing structure. During the ultra-high pressure detection process, the valve will be subjected to a strong pressure generated by the supercharger 8. Through the strong thrust provided by the hydraulic column 203, the hydraulic plate 204 is tightly pressed on the fixed valve 12 to ensure that the valve will not move or break due to excessive pressure.
