Description

Technical Field

[0001] The utility model relates to the technical field of safety valves, in particular to a multi-port safety valve. Background Art

[0002] A safety valve is a special valve whose opening and closing parts are in a normally closed state under the action of external force. When the medium pressure in the equipment or pipeline rises above the specified value, the medium is discharged to the outside of the system to prevent the medium pressure in the pipeline or equipment from exceeding the specified value. The safety valve belongs to the automatic valve category and is mainly used in boilers, pressure vessels and pipelines to control the pressure not to exceed the specified value. It plays an important protective role in personal safety and equipment operation. Note: The safety valve must undergo a pressure test before use.

[0003] After searching, the published patent number CN218118742U mentioned a multi-port safety valve that is easy to install for mechanical engineering. In order to solve the problem that the existing multi-port safety valve is inconvenient to install and the medium is easy to splash around during pressure relief, causing pollution. The lower ends of both sides of the main bracket are equipped with a second connection port, the second connection port is fixedly connected to the main bracket, the outside of the second connection port is equipped with a fixed anti-slip part, the fixed anti-slip part is connected to the second connection port through a slot, the upper end of the main bracket is equipped with a pressure relief cap, the pressure relief cap is slidably connected to the main bracket through a slot, an elastic anti-leakage pad is provided between the pressure relief cap and the main bracket, the elastic anti-leakage pad is fixedly connected to the pressure relief cap and the main bracket, the lower end of the outside of the pressure relief cap is equipped with a pressure relief hole, and the outside of the pressure relief cap is equipped with an anti-splashing bracket.

[0004] Although the above solution solves the problems raised in the background art, the following shortcomings still exist: the compression spring is prone to shaking during the process of being stressed, resulting in poor pressure relief effect and low practicality. Utility Model Content

[0020] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

Several embodiments of the present invention are provided. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0025] A multi-port safety valve includes a bracket body 1, a first connection port 2 is provided on the outside of the bracket body 1, a second connection port 3 is provided on the side of the outside of the bracket body 1 near the first connection port 2, a telescopic tube 4 is movably connected to the inside of the bracket body 1, a limit block 5 is fixedly installed on the side of the inside of the bracket body 1 near the telescopic tube 4, an adjustment structure 6 is fixedly connected to the side of the inside of the bracket body 1 away from the telescopic tube 4, and a sealing gasket 7 is fixedly connected to the top of the telescopic tube 4;

[0026] The adjustment structure 6 includes a fixed block 601 fixedly connected to the inner side of the bracket body 1 away from the telescopic tube 4. A fixed tube 602 is fixedly installed on one end of the fixed block 601, and a connecting rod 603 is movably connected to the inner side of the fixed tube 602, thereby connecting the connecting pipe to the interior of the bracket body 1. When the pressure of the medium inside the bracket body 1 is too high, the medium enters the interior of the fixed tube 602, driving the connecting rod 603 to move upward along the fixed tube 602, and at the same time driving the telescopic tube 4 and the sealing gasket 7 to move upward. The telescopic tube 4 is limited by the limit block 5, and the pressure relief effect is improved under the cooperation of the fixed block 601, the spring 604 and the pressure relief hole 9.

[0027] The outside of the telescopic tube 4 is provided with a pressure relief hole 9 that is compatible with the limit block 5. There are two limit blocks 5. A spring 604 is provided on the outside of the fixed tube 602. The bottom end of the sealing gasket 7 is fixedly connected to the top of the telescopic tube 4, thereby connecting the connecting pipe to the inside of the bracket body 1. When the internal medium pressure of the bracket body 1 is too high, the medium enters the inside of the fixed tube 602, driving the connecting rod 603 to move upward along the fixed tube 602, and at the same time driving the telescopic tube 4 and the sealing gasket 7 to move upward. The limit block 5 limits the telescopic tube 4, and the pressure relief effect is improved with the cooperation of the pressure relief hole 9. The fixed block 601 fixes the fixed tube 602. The rebound force generated by the deformation of the spring 604 drives the telescopic tube 4 to reset, thereby enhancing practicality.

[0028] In this embodiment, please refer to Figure 1 The bottom end of the bracket body 1 is fixed with a fixing seat 8, so that the device can be easily installed and fixed through the fixing seat 8 and the mounting hole 10;

[0029] The four corners of the top of the fixing base 8 are all provided with mounting holes 10, so that the device can be easily installed and fixed through the fixing base 8 and the mounting holes 10, thereby improving stability.

[0030] The working process of the present utility model is as follows: when in use, check whether the appearance of the equipment is damaged. After the inspection, the equipment is installed and fixed through the fixing seat 8 and the mounting hole 10, and the connecting pipe is connected to the inside of the bracket body 1. When the internal medium pressure of the bracket body 1 is too large, the medium enters the inside of the fixed tube 602, driving the connecting rod 603 to move upward along the fixed tube 602, and at the same time driving the telescopic tube 4 and the sealing gasket 7 to move upward. The telescopic tube 4 is limited by the limit block 5, and the pressure relief effect is improved with the cooperation of the pressure relief hole 9. In addition, the fixed tube 602 is fixed by the fixing block 601, and the rebound force generated by the deformation of the spring 604 drives the telescopic tube 4 to reset, which enhances practicality and has promotion value.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
