In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the utility model in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to more clearly illustrate the technical solutions of the embodiments of the utility model, the drawings required for use in the embodiments will be briefly introduced below. It should be understood that the following drawings only show certain embodiments of the utility model and therefore should not be regarded as limiting the scope. For ordinary technicians in this field, other relevant drawings can be obtained based on these drawings without paying creative work.

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0019] Example

[0020] like Figure 1 As shown, a pressure relief device suitable for a high-pressure homogenizer includes a high-pressure homogenizer 1, to which a porous plate 2 is connected, the porous plate 2 is connected to one end of a high-pressure pipe 3, and the high-pressure pipe 3 is connected to the high-pressure homogenizer 1, the other end of the high-pressure pipe 3 is connected to one end of a high-pressure three-way pipe 4, the second end of the high-pressure three-way pipe 4 is connected to the air inlet end of a pressure relief valve 5, the third end of the high-pressure three-way pipe 4 is connected to a pressure sensor 6, and the pressure relief valve 5 is provided with a pressure relief port 7.

[0021] In the present invention, the pressure sensor 6 is connected to a control device 8, wherein the control device 8 is a PLC.

[0022] The maximum pressure resistance value of the pressure relief valve 5 in the present invention is 60,000 psi.

[0023] The utility model adds a pressure detection and feedback device (i.e., a pressure sensor and a PLC) in the high-pressure section, which can effectively detect the pressure situation and set the overpressure protection pressure, thereby achieving the purpose of protecting the equipment.

[0024] At the same time, a pressure relief valve is added. Due to the high viscosity, if the process stops in the middle (1. Active emergency stop, 2. Overpressure shutdown), the material will remain in the channel, and there is still a certain pressure at this time. If it is disassembled directly, it may cause harm to personnel. Through the pressure relief valve, part of the material in the channel can be discharged through the pressure relief valve to achieve pressure balance, preventing the positive pressure shock from damaging the human body during the disassembly process.

[0025] If the material blocks the equipment during operation, it is often necessary to stop the machine for maintenance, which takes a long time. The pressure relief valve can be used to discharge the blocked material from the pressure relief valve, reducing the disassembly time.

[0026] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0028] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or vertical, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0029] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
