[0016] The technical scheme of the utility model will be described below in conjunction with the embodiments, obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0017] Please refer to Figs. 1-3 The utility model provides a technical scheme:

[0018] A pressure control valve group, including valve body 101, the gas passage 201 is set up in valve body 101. In order to facilitate the connection equipment, the first joint 401, the second joint 402 and the third joint 403 are installed on valve body 101 at intervals, and the first joint 401, the second joint 402 and the third joint 403 are all communicated with the gas passage 201. Wherein the first joint 401 is communicated with the outside world, the second joint 402 is communicated with the corresponding equipment, and the third joint 403 is communicated with the vacuum pump, and the vacuum pump injects high-pressure gas into the gas passage 201 through the third joint 403.

[0019] In order to detect the gas pressure in the gas passage 201 of the control valve group in real time when working, a pressure sensor 501 is installed on the valve body 101. The valve body 101 is also provided with a control mechanism for controlling the on-off of the first joint 401 and the on-off of the second joint 402, and the pressure sensor 501 is electrically connected with the control mechanism.

[0020] Specifically, the control mechanism in the embodiment includes a first electromagnetic valve 601 and a second electromagnetic valve 602, both of which are installed on the valve body 101, the first electromagnetic valve 601 is used to control the opening and closing of the first joint 401, and the second electromagnetic valve 602 is used to control the opening and closing of the second joint 402; the first electromagnetic valve 601 and the second electromagnetic valve 602 are electrically connected with the pressure sensor 501.

[0021] In order to facilitate the cleaning of the gas channel 201, the gas channel 201 penetrates through the valve body 101 in the embodiment, and a sealing plug 301 is installed at both ends of the gas channel 201 to plug the two ends of the gas channel 201, so as to prevent the gas in the gas channel 201 from leaking out of the two ends of the gas channel 201 when the control valve group is working. When cleaning the gas channel 201, the two sealing plugs 301 are removed.

[0022] In order to improve the sealing performance of the sealing plug 301 to the gas channel 201, a plurality of sealing rings 701 are sleeved on any sealing plug 301 in the embodiment. The sealing ring 701 in the embodiment is an FFKM O-shaped sealing ring 701.

[0023] Working principle:

[0024] Before use, the matched vacuum pump is connected with the third joint 403 through a pipeline, and the second joint 402 is connected with the equipment through a pipeline.

[0025] First, the first joint 401 is plugged by operating the first electromagnetic valve 601, and the second joint 402 is opened by operating the second electromagnetic valve 602, and then the pressure sensor 501 can measure the air pressure in the gas channel 201. At this time, since the gas channel 201 is connected with the equipment through the second joint 402, the air pressure value in the gas channel 201 is equal to the air pressure value in the equipment.

[0026] When the air pressure value in the equipment is lower than the required pressure value, the first electromagnetic valve 601 plugs the first joint 401, and the second electromagnetic valve 602 opens the second joint 402. Then the vacuum pump works, the third joint 403, the gas channel 201 and the second joint 402 form a passage, and high-pressure gas can be injected into the equipment to increase the pressure in the equipment until the required pressure value is reached. During this process, the pressure sensor 501 continuously detects the air pressure in the gas channel 201.

[0027] When the air pressure value in the equipment is higher than the required pressure value, pressure relief is needed at this time. The pressure sensor 501 transmits the detected signal value to the corresponding control system, and the control system controls the first electromagnetic valve 601 to open the first joint 401, at this time the gas in the equipment can be discharged outward in turn through the second joint 402, the gas channel 201 and the first joint 401, so as to achieve the purpose of pressure relief.

[0028] The above merely describes preferred embodiments of the present application, and it should be understood that the present application is not limited to the forms disclosed herein, and should not be considered as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concepts described herein, by the above teachings or related art or knowledge. Any modification and change made by those skilled in the art without departing from the spirit and scope of the present application shall be within the protection scope of the claims of the present application.
