[0004] The existing detection device cannot ensure that the valve can be connected quickly when detecting the valve, which leads to a decrease in the use effect of the valve and even a decrease in the detection efficiency.

[0005] Therefore, we propose a valve splash test detection device and method in static water under air pressure environment to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide a device and method for testing the valve splash test in still water under an air pressure environment, so as to solve the problem that the above-mentioned background technology cannot ensure the rapid connection of the valve, thereby reducing the use effect of the valve and causing a decrease in detection efficiency.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a valve splash test device in still water under air pressure environment, comprising an organic glass box, a detection mechanism is symmetrically arranged inside the organic glass box, a valve mechanism is arranged inside the organic glass box, a clamping mechanism for clamping the valve mechanism is arranged at the inner bottom of the organic glass box, a detection auxiliary mechanism is arranged on the outer side of the organic glass box, the organic glass box comprises a box body, the detection mechanism comprises a connecting joint, a docking plate is arranged at one end of the connecting joint, a sealing ring is arranged on the outer side of the docking plate, and a connecting head is arranged at the other end of the connecting joint; The valve mechanism comprises a valve body, the connecting joint is connected to two ends of the valve body, the two ends of the valve body are fixedly mounted with docking flanges, and the sealing ring is sleeved on the outer side of the docking flanges.

[0013] Preferably, two hoses are connected to the top of the communicating vessel, and one end of the hose is connected to one end of a connecting head.

[0014] Preferably, a pressure pipe is fixedly connected to the side of the hose, and a pressure instrument is fixedly connected to one end of the pressure pipe.

[0015] A method for testing a valve in still water splash test under an air pressure environment comprises the following steps: S1. When the valve needs to be inspected, the valve body is placed inside the box. During the placement process, the valve body is raised and lowered to a suitable height by the electric lifting column, and the valve body is placed on the bottom support plate. At the same time, the lateral push rod is used to control the extension and retraction adjustment of the clamping block, thereby stably clamping the valve body.

[0016] S2. Then, the connecting joint is used to cooperate with the docking plate to connect the docking flanges at both ends of the upper valve body, and the sealing ring is covered on the outside of the docking flange to ensure the sealing performance. The connecting joint is connected to the upper hose through the connecting head, and the upper communicating vessel is connected through the hose, and then the communicating vessel is connected to the delivery pump, and a right-angle pipe is arranged at the bottom of the delivery pump to connect with the interior of the box body, which is conducive to adding water to the interior of the box body during use, and then the water source is pumped out through the right-angle pipe through the delivery pump, and then delivered to the interior of the connecting joint through the communicating vessel and the hose, and then connected with the interior of the valve body through the connecting joint, and then water source is added to the interior and a pressure test is performed. If there are cracks or damage, the water pressure will cause the inside of the valve body to spray out, and the water inside the box body will splash, so as to measure the valve quality. If there is no spraying, it means that the valve quality is up to standard.

[0017] S3. During the detection process, the pressure gauge on the pressure instrument can detect the pressure at the output of the two hoses, thereby ensuring precise control and avoiding the problem of reduced detection effect caused by insufficient pressure or excessive pressure.

[0018] S4. After the test is completed, the electric telescopic rod contracts, thereby driving the connecting plate and the connecting joint to move to both sides, so that the docking plate is separated from the docking flanges at both ends of the valve body.

[0019] S5. Then, the clamping block is separated from the valve body by contracting the lateral push rod, so that the valve mechanism can be quickly removed, making it convenient to inspect the next set of valve mechanisms.

The connecting joint is connected to the upper hose through the connecting head, and the upper communicating vessel is connected to the conveying pump through the hose. The communicating vessel is then connected to the delivery pump, and a right-angle pipe is arranged at the bottom of the delivery pump to communicate with the inside of the box body, which is conducive to adding water to the inside of the box body during use, and then the water source is pumped out through the conveying pump and the right-angle pipe, and then delivered to the inside of the connecting joint through the communicating vessel and the hose, and then connected to the inside of the valve body through the connecting joint, and then water source is added to the inside and pressure test is performed. If there are cracks or damage, the water pressure will cause the inside of the valve body to spray out, and the water inside the box body will splash, so as to measure the quality of the valve. If there is no spraying, it means that the valve quality is good. 2. The electric lifting column is installed and supported by the bottom mounting plate, and the bottom support plate is raised and lowered by the electric lifting column. The bottom support plate supports the valve mechanism, which makes it convenient to adjust the height of the valve mechanism during testing so that it can be adjusted to a suitable height for connection, thereby improving the convenience of operation.

[0029] like Figure 5 As shown, the detection auxiliary mechanism 5 includes a right-angle tube 501, one end of which is provided with a delivery pump 502, and the top of the delivery pump 502 is provided with a connecting vessel 503, which is connected to the interior of the box body 101 through the right-angle tube 501, so as to facilitate the extraction of water source inside the box body 101, and then transport it to the hose 504 through the delivery pump 502 and the connecting vessel 503, thereby realizing the effect of circulation flow, which is beneficial to saving water resources and ensuring the detection effect at the same time.

[0030] like Figure 5 As shown, two hoses 504 are connected to the top of the communicating vessel 503, and one end of the hose 504 is connected to one end of the connector 204. The water source can be further transported through the hose 504, thereby improving the detection effect.

[0032] The working principle of the whole mechanism is as follows: when the valve needs to be inspected, the valve body 401 is placed into the box body 101, and the electric lifting column 302 is used to adjust the height to a suitable height during the placement process, and the valve body 401 is placed on the bottom support plate 303.

If there is a crack or damage, the water pressure will cause the inside of the valve body 401 to spray out, and the water inside the box 101 will splash, and then the valve quality is measured. If there is no spraying, it means that the valve quality is passed. During the detection process, the pressure gauge on the pressure instrument 506 can detect the pressure at the output of the two hoses 504, thereby ensuring precise control and avoiding the problem of reduced detection effect caused by insufficient pressure or excessive pressure. After the detection is completed, the electric telescopic rod 205 contracts, and then drives the connecting disk 206 and the connecting joint 201 to move to both sides, so that the docking disk 202 is separated from the docking flanges 402 at both ends of the valve body 401, and then the clamping block 306 is driven to separate from the valve body 401 by the contraction of the lateral push rod 305, so that the valve mechanism 4 can be quickly removed, which is convenient for the detection of the next group of valve mechanisms 4.
