Description

Technical Field

[0001] The invention relates to the technical field of water meter detection equipment, and in particular to a pressurized device and a method for increasing pressure by using the device. Background Art

[0002] Water meter inspection is a necessary process before the water meter leaves the factory. During the water meter inspection process, a 3-meter-high water pipe is usually required to be pressed to provide a stable water flow to the water meter. However, this practice is usually limited by the indoor height of the factory building. If the indoor height is lower than 3 meters, the existing operation of using a 3-meter-high water pipe to be pressed will not be possible, which means that a stable water flow cannot be provided to the water meter during the water meter inspection process, seriously affecting the progress of the water meter inspection process. Therefore, it is very important to be able to set up a pressurized device that is not limited by the indoor height of the factory building for the smooth water meter inspection in the factory. Summary of the invention

[0003] In order to make up for the deficiencies of the prior art, the present invention provides a pressurized device and a method for increasing pressure using the device.

[0004] A compressed device includes two flanges, both flanges are provided with through holes, the two through holes are respectively fixedly connected with a water inlet pipe and a water outlet pipe, a sealing cylinder is also fixedly connected between the two flanges, the water inlet pipe and the water outlet pipe are respectively extended into the sealing cylinder and connected with the two ends of a water hose, wherein an air guide pipe is provided on any one or two flanges. The compressed device described in the present application achieves the purpose of pressurizing the sealing cylinder by filling gas into the sealing cylinder through the air guide pipe, the pressure in the sealing cylinder increases, the water hose in the sealing cylinder will be squeezed, and the water pressure flowing into the water outlet pipe through the water hose will increase; the present application can completely replace the traditional use of a 3-meter-high water pipe for compression, the present application has no requirements for the height of the device, and can effectively avoid the defect of being restricted by the indoor height of the factory during the water meter detection process.

In the above-mentioned configuration, the pressure sensor detects the water pressure of the water flowing out of the water outlet pipe and feeds back the detected value to the PLC controller. When the PLC controller detects that the water pressure value fed back by the pressure sensor is less than a preset pressure value, the PLC controller controls the booster air pump to pump gas into the sealing tube. When the PLC controller detects that the pressure value fed back by the pressure sensor is equal to the preset pressure value, the PLC controller controls the booster air pump to stop working, i.e., stops pumping gas into the sealing tube. Moreover, the setting of the one-way valve can effectively prevent the gas in the sealing cover from leaking through the air duct.

[0010] A method for pressurizing the pressurized device comprises the following steps:

[0011] 1) Press the start button on the controller. After receiving the start command, the controller starts to control the booster pump to pump gas into the sealing cylinder;

[0012] 2) The pressure sensor detects the water pressure of the water flowing out of the outlet pipe and feeds back the detection value to the PLC controller;

[0013] 3) When the PLC controller detects that the water pressure value fed back by the pressure sensor is equal to the preset pressure value, the PLC controller controls the booster air pump to stop pumping gas into the sealing tube.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

The present application has no requirements for the height of the device and can effectively avoid the defect of being restricted by the indoor height of the factory building during the water meter detection process.

The water outlet pipe 3 is connected to a pressure sensor 9, and also includes a PLC controller 10. The pressure sensor 9, the PLC controller 10, and the booster air pump 7 are electrically connected in sequence.

[0022] The two flanges 1 are detachably connected with a fastening device, which includes at least two connecting rods 11. In the first embodiment, four connecting rods 11 are used, and both ends of the connecting rods 11 pass through perforated connecting nuts 12 provided on the two flanges 1 respectively.

[0023] In addition, a drainage hole is provided on the flange 1 connected to the water inlet pipe 2 . The drainage hole is communicated with the sealing cylinder 4 , and a drainage valve 13 is connected to the drainage hole.

[0024] When the present application is used, the end of the water inlet pipe 2 that is not connected to the flange 1 faces downward, and the end of the water outlet pipe 3 that is not connected to the flange 1 faces upward. The working principle of the first embodiment of the present application is: the staff presses the start button on the controller, and the controller receives the start command and starts to control the booster air pump to pump gas into the sealing cylinder. The pressure in the sealing cylinder increases, the water hose will be squeezed, and the water pressure flowing into the water outlet pipe through the water hose will increase; and the pressure sensor detects the water pressure of the water flowing out of the water outlet pipe and feeds back the detection value to the PLC controller; when the PLC controller detects that the water pressure value fed back by the pressure sensor is equal to the preset pressure value, the PLC controller controls the booster air pump to stop pumping gas into the sealing cylinder. At this time, the water pressure in the water outlet pipe reaches the pressure value preset by the PLC controller.
