A test stand is provided between the test top plate and the test base. A lower clamp is fixedly connected to the test stand, and an upper clamp is provided above the lower clamp. The upper clamp is provided with a first linear reciprocating motion mechanism for controlling vertical up-and-down movement. A plug is also provided above the lower clamp, and a second linear reciprocating motion mechanism for controlling vertical up-and-down movement is provided on the plug. A water tank for holding liquid is also fixedly connected to the test stand, and the water tank is located below the upper clamp and the plug. An air passage is opened inside the plug, with the air outlet located at the bottom and the air inlet located on the side. A pressurized air pipe connected to an external air source is connected to the air inlet.

[0005] The present invention is further configured such that: a drain pipe is provided at the bottom of the water tank, the outer wall of the drain pipe is provided with external threads, and a pipe cap for opening and closing the pipe opening is threadedly connected to the drain pipe.

[0006] The present invention is further configured such that the water tank is located below the lower clamp.

[0008] The present invention is further configured such that: the lower clamp is provided with lower positioning wings on the left and right sides respectively; and the upper clamp is provided with upper positioning wings on the left and right sides respectively.

[0009] The present invention is further configured such that: the first linear reciprocating motion mechanism and the second linear reciprocating motion mechanism are both push rod cylinders fixedly connected to the test stand.

[0010] In summary, the present invention has the following beneficial effects: The heating water valve anti-leakage testing device involved in the present invention uses a heating water valve in a closed state at the clamping point, supplies air to one end and detects whether there is air leakage at the other end. If there is leaking gas, it will flow into the water tank along the pipe and generate bubbles. The judgment is intuitive, and the overall structure is simple, the failure rate is low, the functions are complete, and the practicality is strong. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0014] Example 1 See Figures 1 to 3 , Figure 5 As shown, the heating water valve leak prevention testing device involved in this embodiment includes a test base 1 and a test top plate 2. A test stand 3 is provided between the test top plate 2 and the test base 1. A lower clamp 4 is fixedly connected to the test stand 3. An upper clamp 5 is provided above the lower clamp 4. A first linear reciprocating motion mechanism 6 for controlling vertical up and down movement is provided on the upper clamp 5. A plug 7 is also provided above the lower clamp 4. A second linear reciprocating motion mechanism 8 for controlling vertical up and down movement is provided on the plug 7. A water tank 9 for holding liquid is also fixedly connected to the test stand 3. The water tank 9 is located below the upper clamp and the plug. An air passage (not shown) is opened in the plug 7. The air outlet of the air passage is located at the bottom and the air inlet is located on the side. A pressurized air pipe 10 connected to an external air source is connected to the air inlet.

[0015] Furthermore, the water tank 9 is located below the lower clamp 4; the water tank 9 is connected to the lower clamp 4.

[0016] Furthermore, both the first linear reciprocating motion mechanism 6 and the second linear reciprocating motion mechanism 8 are push rod cylinders fixedly connected to the test stand 3.

[0017] In this implementation plan, first, add an appropriate amount of water to the water tank 9, then place the main body of the heating water valve 100 to be tested in the lower clamp 4, adjust the position so that one valve port faces upward and the other valve port is submerged in water, then the upper clamp 5 moves downward to clamp the heating water valve 100 to complete the clamping, then the lower plug 7 moves downward to close the upper valve port and supply air to the pressurized air pipe 10, and finally observe whether there are bubbles generated in the water tank 9. If there is a leak, there will be bubbles; otherwise, it is qualified.

[0018] Example 2 See Figures 1 to 5 As shown, the heating water valve anti-leakage testing device involved in this embodiment is further configured based on embodiment 1, wherein the bottom of the water tank 9 is provided with a drain pipe 11, the outer wall of the drain pipe 11 is provided with external threads, and the drain pipe 11 is threadedly connected with a pipe cap 12 for opening and closing the pipe opening.
