Description

TECHNICAL FIELD

[0001] The application relates to the technical field of pipeline testing, in particular to a water supply pipeline plugging pressure testing device. BACKGROUND

[0002] As a carrier of drinking water, the water supply pipeline needs to be applied in a large amount. The water supply pipeline is mainly made of sanitary-grade polyvinyl chloride (PVC) resin, and a proper amount of stabilizer, lubricant, filler and color enhancer is added and then extruded by a plastic extruder and injection molded by an injection molding machine. The water supply pipeline is connected in sections when laid, and therefore needs to be pressure tested to detect the sealing performance of the pipeline connection. The end of the pipeline needs to be plugged before pressure testing.

[0003] The existing patent (publication number: CN220542662U) discloses a plastic water supply pipeline plugging pressure testing device which can plug different diameter pipelines, improve the use range, enhance the connection firmness between the device and the pressure testing pipe, and improve the safety. The device comprises two plugging plates, two input pipes, a plugging mechanism and a pressing mechanism. The two plugging plates are respectively located at the two ends of the pressure testing pipeline. The two input pipes are respectively fixedly installed in the middle of the two plugging plates. A water inlet valve is installed on the left input pipe, and a quick connector is installed on the input end of the input pipe. A pressure gauge is connected to the right end of the other input pipe, and a discharge valve is connected to the right end of the input pipe. The plugging mechanism is installed on the side wall of the plugging plate and is sleeved on the outer side wall of the input pipe. The pressing mechanism is installed on the side wall of the plugging plate and is connected with the plugging mechanism.

[0004] When the device is used, the two plugging plates are placed at the two ends of the pressure testing pipeline respectively, the input pipes are inserted into the two ends of the pressure testing pipeline, the pressure testing pipeline is inserted into the outer hoop sleeve, and the two knobs are rotated to drive the rotating rods to rotate, and the rotating rods drive the threaded blocks to move towards the plugging plates. However, the operation is relatively complicated, which affects the testing efficiency. In addition, when the user does not rotate the knob to the right position during installation, the sealing performance of the pipeline is easily affected, and the accuracy of the test result is reduced. CONTENT OF THE UTILITY MODEL

[0005] In view of the deficiencies of the prior art, the application provides a water supply pipeline plugging pressure testing device which has the advantages of high testing efficiency and solves the problems in the background art.

[0007] The upper part of the filter screen is provided with two blocking plates, and the inner side of the blocking plates is fixedly connected with a conical blocking head.

At the same time, the pressure sensor installed in the left blocking head can monitor the pressure change in the pipeline in real time, ensuring the accuracy and reliability of the pressure test. By setting the filter screen and the water storage tank, the device can filter and collect the experimental water, effectively saving water resources and reducing the impact on the environment. Compared with the traditional manual rotation knob plugging method, the device drives the bidirectional threaded rod to rotate through the motor, ensuring the close fit between the blocking plate and the pipeline, thereby enhancing the sealing performance and improving the accuracy of the test results.

[0009] Further, the upper surface of the filter screen is fixedly installed with two support frames, and the top end of the support frame is fixedly connected with a placing seat.

[0010] Through the above scheme, the placing seat can be placed in the pipeline to be detected.

[0011] Further, the water supply pipe is provided with a one-way valve at one end.

[0012] Through the above scheme, the one-way valve can effectively prevent the water source from flowing backward.

[0013] Further, the left and right inner side walls of the fence frame are rotatably connected with two bidirectional threaded rods, and the two blocking plates are threadedly connected with the two bidirectional threaded rods.

[0014] Through the above scheme, the two blocking plates can be moved closer or farther away from each other through the bidirectional threaded rods, thereby achieving the effect of automatic connection with the pipeline to be detected.

[0015] Further, the water storage tank is provided with a pump body on one side, and the input end of the pump body is fixedly communicated with the bottom end of the side surface of the water storage tank. The output end of the pump body is fixedly communicated with a corrugated pipe, and the other end of the corrugated pipe is fixedly communicated with the water supply pipe.

[0016] Through the above scheme, the pump body can achieve the purpose of water delivery.

[0017] Further, one end of each of the two bidirectional threaded rods is fixedly connected with the output end of an external motor.

[0018] Through the above scheme, the external motor can provide power for the rotation of the bidirectional threaded rod.

[0019] Further, the front of the enclosure frame is provided with a control host.

[0020] Through the above scheme, through the setting of the control host, the operation control of the whole pressure test device can be realized, including starting the pump body, monitoring the data of the pressure sensor, controlling the motor to drive the bidirectional threaded rod to rotate and other functions, so that the whole pressure test process is more automated and intelligent.

[0021] Further, the bottom of the water storage tank is provided with a set of moving wheels.

[0022] Through the above scheme, through the setting of the moving wheels, the whole pressure test device can be conveniently moved, which is convenient for plugging pressure test of the water supply pipeline at different places, improves the flexibility and practicality of the device. At the same time, the brake device is also arranged on the moving wheel, which can fix the device when needed to prevent it from sliding or moving, and ensure the safety and stability of the test process.

[0023] Compared with the prior art, the technical scheme of the present application has the following beneficial effects:

[0024] The water supply pipeline plugging pressure test device adopts the threaded connection design of the bidirectional threaded rod and the plugging plate, so that the plugging plate can be quickly and accurately connected with the pipeline to be detected, realizing efficient plugging effect. At the same time, the pressure sensor installed in the left plugging head can monitor the pressure change in the pipeline in real time, ensuring the accuracy and reliability of the pressure test. By setting the filter screen and the water storage tank, the device can realize the filtration and collection of experimental water, effectively saving water resources and reducing the impact on the environment. Compared with the traditional manual rotary knob plugging method, the device drives the bidirectional threaded rod to rotate through the motor, ensuring the close fit between the plugging plate and the pipeline, thereby enhancing the sealing performance and improving the accuracy of the test results.
