Description

Technical Field

[0001] This application relates to the technical field of instrument testing, and in particular to a testing device for a solenoid valve flow meter. Background Technology

[0002] After assembly, solenoid valves or flow meters must be tested with water or air. The traditional testing method is to screw them onto a test bench using threads.

[0003] Regarding the aforementioned technologies, the inventor believes that screwing on the solenoid valve would slow down the testing speed and reduce efficiency. Utility Model Content

[0004] To improve testing efficiency, this application provides a testing device for electromagnetic valve flow meters.

[0005] The electromagnetic valve flowmeter testing device provided in this application adopts the following technical solution:

[0006] A solenoid valve flow meter testing device includes a base plate, a cylinder, a sealing head, an input pipe, and a mounting block. The cylinder is mounted on the base plate, the sealing head is mounted on the output shaft of the cylinder, and the mounting block is mounted on the base plate. The base plate has a mounting groove. A connector is provided between the sealing head and the cylinder output shaft. The connector has an inner cavity. The input pipe is mounted on the connector and communicates with the inner cavity. A channel is provided inside the sealing head, and the channel communicates with the inner cavity.

[0007] With the above technical solution, when testing is required, the solenoid valve with the flow meter is placed in the mounting slot, and then the cylinder is activated. The cylinder drives the sealing head forward to press against the opening of the solenoid valve, and then water or air is introduced into the solenoid valve through the input pipe, thereby testing the flow meter and improving testing efficiency.

[0008] Optionally, the sealing head is made of polyurethane rubber.

[0009] Through the above technical solution, polyurethane rubber can make the sealing head softer and more easily deformed. When the sealing head comes into contact with the solenoid valve opening, it deforms, thereby sealing the gap between the sealing head and the opening and improving the test accuracy.

[0010] Optionally, the base plate is provided with a connecting block, which includes a horizontal block and a vertical block. The vertical block is vertically disposed on one side of the horizontal block, the horizontal block is mounted on the base plate, the cylinder is mounted on the horizontal block, and the connecting block is provided with a connecting hole for the cylinder output shaft to pass through.

[0011] The beneficial effects of this utility model are as follows: When testing is required, the solenoid valve with the flow meter is placed in the mounting slot, and then the cylinder is activated. The cylinder drives the sealing head forward to press against the opening of the solenoid valve. Then, water or air is input into the solenoid valve through the input pipe, thereby testing the flow meter and improving testing efficiency. Attached Figure Description

[0014] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0015] This application discloses a solenoid valve flow meter testing device.

[0016] Reference Figure 1 The electromagnetic valve flow meter testing device includes a base plate 1, a cylinder 2, a sealing head 3, an input pipe 4, and a mounting block 5. The cylinder 2 is mounted on the base plate 1, the sealing head 3 is mounted on the output shaft of the cylinder 2, and the mounting block 5 is mounted on the base plate 1. The base plate 1 has a mounting groove 51. A connector 21 is provided between the sealing head 3 and the output shaft of the cylinder 2. The connector 21 has an inner cavity 211. The input pipe 4 is mounted on the connector 21 and communicates with the inner cavity 211. A channel 31 is provided inside the sealing head 3, and the channel 31 communicates with the inner cavity 211.

[0017] When testing is required, the solenoid valve with the flow meter is placed into the mounting slot 51, and then the cylinder 2 is activated. The cylinder 2 drives the sealing head 3 forward to press against the opening of the solenoid valve. Then, water or air is introduced into the solenoid valve through the input pipe 4 to test the flow meter, thereby improving the testing efficiency.

[0018] The sealing head 3 is made of polyurethane rubber.

[0019] Polyurethane rubber makes the sealing head 3 softer and more prone to deformation. When the sealing head 3 comes into contact with the solenoid valve opening, it deforms, thereby sealing the gap between the sealing head 3 and the opening and improving the test accuracy.

[0020] A connecting block 6 is provided on the base plate 1. The connecting block 6 includes a horizontal block 61 and a vertical block 62. The vertical block 62 is vertically arranged on one side of the horizontal block 61. The horizontal block 61 is installed on the base plate 1. The cylinder 2 is installed on the horizontal block 61. A connecting hole 621 for the output shaft of the cylinder 2 to pass through is opened on the block.

[0021] The implementation principle of the solenoid valve flow meter testing device in this application embodiment is as follows: When testing is required, the solenoid valve with the flow meter is placed in the mounting groove 51, and then the cylinder 2 is activated. The cylinder 2 drives the sealing head 3 forward to press against the opening of the solenoid valve. Then, water or air is input into the solenoid valve through the input pipe 4, thereby testing the flow meter and improving the testing efficiency.

[0022] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
