Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a solenoid valve comprehensive performance aging test chamber. Background Technology

[0002] Solenoid valves are electromagnetically controlled industrial devices, fundamental components in automation systems used to control fluids. They are commonly used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control. There are many types of solenoid valves, each playing a different role in the control system. The most common types are check valves, safety valves, directional control valves, and speed regulating valves. In the use of smart toilets, the performance of the solenoid valve affects its inlet water pressure stabilization effect; therefore, relevant performance testing equipment is needed to ensure that its performance meets national standards.

[0003] However, in practical use, common smart toilet inlet pressure stabilizing solenoid valve performance testing machines have limited functions, and the variety of solenoid valve types and specifications makes it difficult to standardize their fixing methods, thus requiring further improvement. While the patent application with publication number CN218330555U fixes the solenoid valve, its fixing method has certain drawbacks. For example, after placing the solenoid valve inside the U-shaped fixing seat, it is only fixed by a pressing plate on one side of the solenoid valve and a side plate of the U-shaped fixing seat. Furthermore, the side plate of the U-shaped fixing seat is planar, resulting in poor fixing of the solenoid valve and easily affecting the test results. Therefore, this application proposes a comprehensive performance aging test chamber for solenoid valves to solve the above problems, improve the stability of the solenoid valve after fixing, and make its test results more accurate.

The top limiting component is located on one side of the circumferential limiting component. A protective cover is provided on the top surface of the support base to prevent water from splashing from the inside of the water tank to the outside.

[0006] Furthermore, the circumferential limiting component includes a U-shaped fixing seat symmetrically fixed on the top surface of the support base. Two horizontal electric push rods are symmetrically fixed on the inner wall of the U-shaped fixing seat. The included angle between the two electric push rods on the same U-shaped fixing seat is set between 90° and 120°. The transmission ends of the four electric push rods are all oriented towards the solenoid valve.

[0007] Furthermore, the top limiting component includes a stand fixedly disposed on the top surface of the support base located on one side of the U-shaped fixed seat. A crossbar is rotatably disposed on the top surface of the stand. An installation block is fixedly disposed at the end of the crossbar away from the stand. A vertically downward driving cylinder is fixedly disposed on the bottom surface of the installation block.

[0014] This utility model discloses a solenoid valve comprehensive performance aging test chamber. Through the cooperation of a circumferential limiting component and a top limiting component, it achieves separate circumferential and vertical limiting of the solenoid valve. Specifically, four electric push rods in the circumferential limiting component fix four points on the circumferential wall of the solenoid valve, preventing the solenoid valve from shifting horizontally. Additionally, the drive cylinder in the top limiting component acts on the top surface of the solenoid valve, preventing it from moving upwards. This provides a good fixing effect and improves testing accuracy. Furthermore, the circumferential and top limiting components in this application can fix solenoid valves of different sizes and models, making it highly practical.

One end of the electric push rod 42 is fixedly installed on the inner wall of the U-shaped fixed base 41, and the other end, i.e. the transmission end, is set towards the solenoid valve 3.

[0029] That is, the transmission ends of the four electric push rods 42 are all oriented toward the solenoid valve 3; wherein, a pressure sensor is embedded and fixedly installed at the transmission end of the electric push rod 42, and the force-receiving end of the pressure sensor is in contact with the circumferential wall of the solenoid valve 3 to detect the force acting on the solenoid valve 3.

[0030] In a preferred embodiment, the top limiting component 5 includes a stand fixedly disposed on the top surface of the support base 1 on one side of a U-shaped fixed seat 41. A crossbar 52 is rotatably disposed on the top surface of the stand 51. A mounting block 53 is fixedly disposed at the end of the crossbar 52 away from the stand 51. A vertically downward driving cylinder 54 is fixedly disposed on the bottom surface of the mounting block 53. The transmission end of the driving cylinder 54 is used to abut against the top surface of the solenoid valve 3 to be tested.

[0031] In a preferred embodiment, a square groove 6 is provided around the edge of the top surface of the support base 1, and a strip groove 7 is provided on the top surface of the support base 1 between the water pool 2 and the circumferential limiting component 4, and the strip groove 7 is connected to the square groove 6.

[0032] A protective cover 8 is provided on the top surface of the support base 1 to prevent water inside the pool 2 from splashing to the outside.

[0033] In a preferred embodiment, the protective cover 8 includes a box-shaped protective shell 81 corresponding to the square groove 6. A partition plate 82 is fixedly provided inside the protective shell 81 corresponding to the strip groove 6. The bottom surfaces of the four side plates of the protective shell 81 extend into the interior of the square groove 6, and the bottom surfaces of the partition plate 82 extend into the interior of the strip groove 7.

[0034] Both the protective shell 81 and the partition plate 82 are made of transparent material.

[0035] That is, the protective cover 8 is fastened inside the square groove 6 and the strip groove 7 to isolate the water pool 2 separately and prevent water from splashing out.

[0036] In a preferred embodiment, pressure sensors are embedded in the transmission end of the electric push rod 42 and the transmission end of the drive cylinder 54 to monitor the force exerted by the electric push rod 42 and the drive cylinder 54 on the solenoid valve 3, so as to avoid excessive force affecting the solenoid valve 3.

[0039] The working principle of this utility model:

[0040] Before testing, the solenoid valve 3 is installed. Specifically, the solenoid valve 3 is placed between two U-shaped fixing seats 41 and inside the circumferential limiting assembly 4, with the outlet of the solenoid valve 3 corresponding to the water tank 2. Then, the electric push rods 42 are activated, and the four electric push rods 42 extend towards the solenoid valve 3. The transmission end of the electric push rods 42 abuts against the circumferential wall of the solenoid valve 3 to prevent the solenoid valve 3 from shifting in position. When the pressure sensor on the electric push rod 42 detects that the force between the electric push rod 42 and the circumferential wall of the solenoid valve 3 reaches the set threshold range, the electric push rod 42 stops extending, thus completing the circumferential limiting and fixing of the solenoid valve 3.

[0041] Then, the crossbar 51 is rotated above the solenoid valve 3 to control the drive cylinder 54 to work. The piston rod of the drive cylinder 54 extends vertically downward until it abuts against the top surface of the solenoid valve 3. When the pressure sensor on the drive cylinder 54 detects that the force between the drive cylinder 54 and the solenoid valve 3 reaches the set threshold range, the drive cylinder 54 stops working, thus completing the vertical limiting and fixing of the solenoid valve 3. After that, the protective cover 8 is fastened to the square groove 6 for protection. Thus, the limiting and fixing of the solenoid valve 3 is completed. The fixing effect is good, avoiding large positional deviation during the test process, which would affect the test results.
