Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically to a one-way valve sealing detection device for refrigeration equipment. Background Technology

[0002] The refrigeration equipment check valve sealing test device is a special device used to test the sealing performance of check valves in refrigeration systems. Its core function is to use specific technical means to determine whether there are problems such as leakage or poor sealing of the check valve, so as to ensure that the check valve can achieve unidirectional liquid flow and prevent reverse flow in refrigeration equipment.

[0003] The one-way valve sealing test device for refrigeration equipment is mainly divided into three types: 1. Differential pressure method: The one-way valve to be tested and a standard leak-free valve body are placed in the same pressure environment. The pressure difference between the two is detected by a high-precision sensor. If the difference exceeds the threshold, it is judged as a poor seal. 2. Vacuum decay method: A vacuum is drawn into the internal or external chamber of the one-way valve. If the vacuum degree decreases over time, it indicates that there is a leak. 3. Bubble method: The pressurized one-way valve is placed in water (or other test liquid) to see if bubbles are produced. This method can be used to visually determine the location and degree of the leak. It is mostly used for qualitative testing or rough inspection.

[0004] The vacuum decay method for testing the sealing performance of one-way valves in refrigeration equipment requires the following steps when monitoring one-way valves: first, the valve to be tested needs to be fixed on the base using a clamp; then, the upper detector is moved down to fit over the air inlet of the one-way valve; and finally, the air inside the one-way valve is extracted. While this testing method is relatively convenient, different testing devices are required for different models of one-way valves, making the use of the testing device inconvenient and increasing testing costs.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] like Figure 1 - Figure 4As shown, this utility model provides a technical solution: a one-way valve sealing detection device for refrigeration equipment, including a base 1, a control box 11 fixedly connected to the outer side of one end of the base 1, and brackets 12 fixedly connected to the upper sides of both ends of the base 1. A cylinder 13 is fixedly connected to the upper side of the bracket 12, and a valve nozzle 14 is fixedly connected to the lower end of the cylinder 13 through the bracket 12. A clamping assembly 2 is provided on the upper end of the base 1, and the clamping assembly 2 includes a connecting rod 21 provided above the base 1. A clamping plate 22 is fixedly connected to one end of the connecting rod 21, and a rubber pad 2 is fixedly connected to the end of the clamping plate 22 away from the connecting rod 21. 3. A pin assembly 3 is provided at the end of the connecting rod 21 away from the clamping plate 22, and a moving assembly 4 is provided at the end of the pin assembly 3 away from the connecting rod 21. A locking assembly 5 is provided in the middle of the moving assembly 4, and an adjusting assembly 6 is provided at the lower end of the moving assembly 4. Auxiliary components 7 are provided at both ends of the adjusting assembly 6. By cooperating with the pin assembly 3 and the moving assembly 4, the position of the clamping plates 22 on both sides can be adjusted according to the model of the check valve when testing the check valve. The clamping plates 22 can also be quickly replaced according to the model of the check valve, thus reducing the testing cost and improving the testing efficiency.

[0020] like Figure 2 As shown, the pin assembly 3 includes a connecting plate 31 fixedly connected to the end of the connecting rod 21 away from the clamping plate 22, and a screw cylinder 32 is rotatably connected to the outer end of the connecting plate 31 away from the connecting rod 21 via a flange. An insert plate 33 is fixedly connected to the middle end of the connecting plate 31 near the screw cylinder 32. After replacement, the clamping plate 22 and the rubber pad 23 are driven by the connecting rod 21 to insert the insert plate 33 into the positioning cylinder 42. During the insertion of the insert plate 33, the screw cylinder 32 is screwed, so that the screw cylinder 32 is sleeved on the outside of the positioning cylinder 42 through thread engagement with the positioning cylinder 42.

[0021] like Figure 1 As shown, the moving component 4 includes a connecting plate 41 disposed at the end of the screw cylinder 32 away from the connecting plate 31, and a positioning cylinder 42 is fixedly connected to the middle of the connecting plate 41. Screwing the screw cylinder 32 causes it to push the connecting plate 31 and the insert plate 33 to move through the thread engagement with the positioning cylinder 42. When the screw cylinder 32 and the insert plate 33 are disengaged from the positioning cylinder 42, the clamping plate 22 and the rubber pad 23 are removed.

[0022] like Figure 4 As shown, the inner side of the positioning cylinder 42 is sleeved on the outer side of the insert plate 33, and the end of the positioning cylinder 42 away from the connecting plate 41 is threadedly engaged with the inner side of the screwing cylinder 32. Tightening the screwing cylinder 32 causes it to push the connecting plate 31 and the insert plate 33 to move through the thread engagement with the positioning cylinder 42. When the screwing cylinder 32 and the insert plate 33 are disengaged from the positioning cylinder 42, the clamping plate 22 and the rubber pad 23 are removed.

[0023] like Figure 4As shown, the positioning assembly 5 includes a positioning cylinder 42 and a support plate 51 fixedly connected to one end near the connecting plate 41. A locking plate 52 is rotatably connected to the upper end of the support plate 51. A spring 53 is spherically hinged to the middle end of the locking plate 52, and the lower end of the spring 53 is spherically hinged to the positioning cylinder 42. The locking plate 52 is pushed by the support plate 51, thereby causing the locking plate 52 to rotate and stretch the spring 53. After the locking plate 52 is pushed, it moves away from the screw cylinder 32, releasing the locking of the screw cylinder 32.

[0024] like Figure 2 As shown, the adjustment assembly 6 includes a motor 61 fixedly connected to the outer side of one end of the base 1, and a double-threaded rod 62 fixedly connected to the output shaft of the motor 61 through the base 1. The end of the double-threaded rod 62 away from the motor 61 is rotatably connected inside the base 1, and threaded plates 63 are threadedly engaged at both ends of the double-threaded rod 62. The upper end of the threaded plate 63 is fixedly connected to the connecting plate 41. When the motor 61 is started, its output shaft drives the double-threaded rod 62 to rotate. After the double-threaded rod 62 rotates, it engages with the threaded plate 63. When the threaded plate 63 moves, it drives the positioning cylinder 42 and the connecting rod 21 to move through the connecting plate 41.

[0025] like Figure 3 As shown, the auxiliary component 7 includes a slide plate 71 fixedly connected to both ends of the threaded plate 63, and a positioning rod 72 is inserted inside the end of the slide plate 71 away from the threaded plate 63. The two ends of the positioning rod 72 are fixedly connected to the base 1, and the threaded plate 63 drives the slide plate 71 to move around the outside of the positioning rod 72.

[0026] Working principle: When testing the check valve, the clamping plate 22 and rubber gasket 23 can be replaced according to the check valve model. During replacement, the clamping plate 52 is first moved under the support of the support plate 51, so that the clamping plate 52 rotates and stretches the spring 53. After the clamping plate 52 is moved, it moves away from the screw cylinder 32, releasing the clamping position of the screw cylinder 32. Then, the screw cylinder 32 is screwed so that it pushes the connecting plate 31 and the insert plate 33 to move through the thread engagement with the positioning cylinder 42. When the screw cylinder 32 and the insert plate 33 are disengaged from the positioning cylinder 42, the clamping plate 22 and rubber gasket 23 are removed. Then, the replaced clamping plate 22 and rubber gasket 23 are driven by the connecting rod 21 to insert the insert plate 33 into the positioning cylinder 42. During the insertion of the insert plate 33, the screw cylinder 32 is screwed, so that the screw cylinder 32 rotates and stretches the spring 53. The cylinder 32 is fitted onto the outside of the positioning cylinder 42 through threaded engagement with the positioning cylinder 42. After installation, the movable clamping plate 52 is released, and the elastic potential energy of the spring 53 pulls the clamping plate 52 back into the screw cylinder 32 to lock and restrict the screw cylinder 32. Then, the one-way valve to be inspected is placed between the two sets of rubber pads 23. Subsequently, the motor 61 is started so that its output shaft drives the double-headed threaded rod 62 to rotate. After the double-headed threaded rod 62 rotates, it engages with the threaded plate 63, allowing the threaded plate 63 to drive the sliding plate 71 to move outside the positioning rod 72. When the threaded plate 63 moves, it drives the positioning cylinder 42 and the connecting rod 21 to move through the connecting plate 41, so that the connecting rod 21 can push the clamping plate 22 and the rubber pad 23 to clamp and fix the lower end of the one-way valve.

[0027] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
