[0006] Preferably, the first connecting hole is connected to the connecting cylinder by a fastener, and the second connecting hole is connected to the fixing hole by a fastener.

[0007] Preferably, a retaining ring is fixedly connected to the bottom surface of the cover, and the inner sidewall of the retaining ring is in contact with the top outer wall surface of the controller body.

[0008] Preferably, the diameter of the retaining ring is larger than the diameter of the top outer wall of the controller body.

[0009] Preferably, a first sealing ring is fixedly connected to the inner sidewall surface of the retaining ring, and the first sealing ring is in contact with the outer wall of the controller body.

[0010] Preferably, the top surface of the base has a groove, in which a second sealing ring is engaged, and the surface of the second sealing ring is in contact with the bottom surface of the controller body. Beneficial effects

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0012] In combination with the structural design of this utility model, the modular design makes disassembly and assembly more convenient under long-term use conditions, while reducing its usage cost and improving its practicality. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] In the description of this utility model, it should be noted that the terms "upper," "lower," "left," "right," "front," "rear," "inner," "outer," "vertical," and "horizontal," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] like Figure 1-4This is a schematic diagram of a pressure controller according to a preferred embodiment of the present invention. In this embodiment, the pressure controller includes a controller body 1, a base 3 connected to the bottom of the controller body 1, a cover 2 connected to the top of the controller body 1, the inside of the controller body 1 communicating with the cover 2 and the base 3, and multiple connecting cylinders 11 fixed to the outer wall of the controller body 1. A first connecting hole 31 is opened on the bottom surface of the base 3 at the position opposite to the connecting cylinders 11. A connecting plate 21 is fixedly connected to the outer wall surface of the cover 2, and a second connecting hole 22 is opened on the surface of the connecting plate 21. A fixing hole 12 is opened on the top surface of the controller body 1. Combined with the structural design of the present invention, by adopting a modular design for the pressure controller, disassembly and assembly are more convenient under long-term use conditions, while reducing the cost of use and improving practicality.

[0024] In this embodiment, the first connecting hole 31 is connected to the connecting cylinder 11 by a fastener 4, and the second connecting hole 22 is connected to the fixing hole 12 by a fastener 4. This structural design allows the modules to be fixedly connected by the fastener 4.

[0025] In this embodiment, a retaining ring 23 is fixedly connected to the bottom surface of the cover 2. The inner side wall of the retaining ring 23 is in contact with the top outer wall surface of the controller body 1. This structural design effectively prevents impurities, liquids, etc. from entering the pressure controller and affecting the service life of the product.

[0026] In this embodiment, the diameter of the retaining ring 23 is larger than the diameter of the top outer wall of the controller body 1. This structural design provides better protection for the controller body 1 and facilitates better splicing.

[0027] In this embodiment, a first sealing ring 24 is fixedly connected to the inner wall surface of the retaining ring 23. The first sealing ring 24 fits against the outer wall of the controller body 1. A groove 32 is opened on the top surface of the base 3.
