Description

Technical Field

[0001] The utility model relates to the technical field of safety valve installation, in particular to a high-pressure sterilizer safety valve installation structure. Background Art

[0002] Autoclave is a kind of equipment widely used in medical, laboratory, food industry and other fields. It is mainly used to kill various microorganisms such as bacteria, fungi, viruses, etc. to ensure the accuracy of working environment and experimental results. However, with the continuous increase of equipment pressure, how to ensure that the autoclave can effectively control the pressure within the normal operating range to prevent the equipment from being damaged or causing safety accidents due to excessive pressure has become an urgent problem to be solved. Therefore, it is of great significance to study and design a safe and reliable installation structure for the use of autoclave.

[0003] For example, the patent publication number is CN205626546U, which is a medical high-pressure steam sterilizer. The high-pressure steam sterilizer has a fast heating speed, good sterilization effect, strong penetration, and is equipped with a low water level alarm device. The electric double internal lock locks the box cover by detecting the internal pressure and the temperature inside the box to ensure greater safety during use. It adopts the latest automatic steam exhaust device to sterilize the liquid matrix without boiling, and can also perform scientific and automated operations.

[0004] A high-pressure steam sterilizer requires a safety valve for venting during use. Although the above device ensures the safety of the device during use, the safety valve is installed with fixed screws. When this installation method is used, the safety valve needs to be removed from the equipment when the thread is rusted during use. The safety valve with fixed screws will rust and wear during repeated disassembly and assembly, causing the connection to get stuck or the interface to be severely worn and difficult to seal. Therefore, the safety valve can only be replaced as a whole, which greatly increases the maintenance cost. For this reason, we propose an installation structure for a high-pressure sterilizer safety valve. Utility Model Content

[0026] like Figure 1 - Figure 4 As shown, the utility model provides a technical solution: a high-pressure sterilizer safety valve installation structure, including an external pipe 1,

[0027] A connecting pipe 2 is installed inside the external pipe 1, a mounting pipe 3 is installed on the outer wall of the top end of the connecting pipe 2, a fixing mechanism 8 is installed on the surface of the mounting pipe 3 and the external pipe 1, and a moving mechanism 9 is installed on the surface of the connecting pipe 2;

[0028] A fixing pipe 4 is installed at the top of the installation pipe 3 , a discharge pipe 6 is installed at one side of the fixing pipe 4 , a power pipe 5 is installed at the top of the fixing pipe 4 , and a pressure mechanism 7 is installed inside the power pipe 5 .

[0029] The moving mechanism 9 comprises:

[0030] A plurality of L-shaped grooves 901 are installed on the inner side of the external pipe 1, a lower fixing block 902 is installed in the L-shaped groove 901, a connecting pipe 2 is installed on the outer side of the lower fixing block 902, an upper fixing block 903 is installed on the outer wall at the top end of the connecting pipe 2, an L-shaped groove 901 is provided on the inner bottom end of the mounting pipe 3, and the upper fixing block 903 is installed in the L-shaped groove 901.

[0031] like Figure 2 As shown, it should be noted that when the safety valve needs to be installed or disassembled, first align the upper fixing block 903 on the connecting pipe 2 with the L-shaped groove 901 on the inner side of the mounting pipe 3. When sliding to the top end, rotating the connecting pipe 2 can fix the upper fixing block 903 in the L-shaped groove 901, and then align the lower fixing block 902 with the L-shaped groove 901 on the inner side of the external pipe 1. When moving to the bottom end, rotating the connecting pipe 2 can fix the lower fixing block 902 in the L-shaped groove 901, thereby realizing the connection between the mounting pipe 3 and the external pipe 1.

[0032] The fixing mechanism 8 comprises:

[0033] A fixing groove 803 is installed on one side of the surface of the external tube 1, and a guide rail 809 is symmetrically installed on the inner side of the fixing groove 803, and a fixing plate 802 is installed on the outer side of the guide rail 809. Moving grooves 808 are symmetrically arranged on both sides of the fixing plate 802, and a guide rail 809 is installed in the moving groove 808. A push plate 801 is installed on the outer bottom end of the fixing plate 802.

A mounting frame 711 is symmetrically installed on the outer wall of the mounting sleeve 710, and the rocker arm 701 is installed on the inner side of the mounting frame 711 by rotating the bolt 713.

[0037] like Figure 4 As shown, it should be noted that the rocking lever 701 can control the lifting and lowering of the pressure rod 712 by rotating the bolt 713 to drive the tip at the top of the rocking lever 701. During the lifting and lowering of the pressure rod 712, the blocking sleeve 707 is driven to move by the brake rod 702. During the movement of the blocking sleeve 707, the reciprocating spring 703 contracts, the discharge pipe 6 is opened, and the material in the high-pressure sterilizer is discharged through the discharge pipe 6.
