Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a dust protected relief valve, including valve body 1, the top of valve body 1 is provided with spring gland 2, spring gland 2's top is provided with dust cover 3, spring gland 2's bottom is provided with expanding spring 4, be provided with valve rod 5 in expanding spring 4's the inner chamber, the bottom of valve rod 5 is provided with valve clack 6, the right side of valve body 1 is provided with pressure release pipe 7, pressure release pipe 7's bottom is provided with bottom plate 8, bottom plate 8's the back is provided with backplate 9, the left side of backplate 9 is provided with curb plate 10, recess 11 has been seted up on backplate 9's the front, be provided with slider 12 in recess 11's the inner chamber, the right side of curb plate 10 is provided with hydraulic telescoping rod 13, hydraulic telescoping rod 13's right side is provided with carriage release lever 14, carriage release lever 14 links to each other with slider 12's front, spout 15 has been seted up on pressure release pipe 7's the back, carriage release lever 14's front runs through spout 15 and extends to pressure release pipe 7's inner chamber, be provided with fan 16 in pressure release pipe 7's the inner chamber, the end of fan 16 flabellum is provided with cleaning brush 17, fan 16 right side links to each other with carriage release lever 14's left side.
The fan 16 is connected with the moving rod 14 through a pin.
In this embodiment, a pin is provided between the moving rod 14 and the fan 16. Therefore, the fan 16 is driven to move left and right in the inner cavity of the pressure release pipe 7 by the left and right movement of the moving rod 14, so that the cleaning brush 17 is driven to move left and right, the inner cavity of the pipeline of the pressure release pipe 7 is cleaned transversely, and the dust removal effect on the inner cavity of the pressure release pipe 7 is achieved.
Wherein the edge of the cleaning brush 17 is tangent to the inner diameter of the pressure relief pipe 7.
In this embodiment, since the cleaning brush 17 is disposed at the end of the fan blade of the fan 16, the rotating fan blade drives the cleaning brush 17 to rotate. Because the edge of the cleaning brush 17 is tangent to the inner diameter of the pressure relief pipe 7, the cleaning brush 17 can clean the inner cavity of the pressure relief pipe 7, and the purpose of dust prevention is achieved.
Wherein, the friction of the groove 11 is small, and the slide block 12 can move left and right in the inner cavity of the groove 11.
In this embodiment, since the slider 12 is connected to the back surface of the moving rod 14, and the slider 12 can only move in the cavity of the groove 11, the moving direction of the moving rod 14 is limited, and only the horizontal movement in the left-right direction is achieved. The friction force of the groove 11 is small, so that the slider 12 can move in the groove 11 more stably, and the moving rod 14 moves more rapidly left and right.
The fan 16 has twelve sets of blades, which are in a circumferential array.
In this embodiment, the fan 16 has twelve sets of blades in a circumferential array, so that the dust removing effect is better.
The working principle is as follows: when the pressure of the device connected with the safety valve is normal, the valve clack 6 cannot move upwards at the moment, and no gas flows through the pressure relief pipe 7. When the atmospheric pressure of device increases, atmospheric pressure intensity can extrude valve clack 6 that is located the bottom this moment, and valve clack 6 can the upward movement to extrude valve rod 5 on the valve clack 6, expanding spring 4 also contracts thereupon, and valve clack 6 is extruded to 7 same heights of pressure release pipe this moment, and inside gas begins to spread from pressure release pipe 7 outwards, and after the atmospheric pressure diffusion, pressure reduces, thereby alleviates the atmospheric pressure in the device, and the atmospheric pressure stability in the device is consequently guaranteed to the relief valve. When the air passes through the pressure relief pipe 7, a strong airflow is generated, and the airflow drives the fan 16 inside the pressure relief pipe 7 to rotate. Since the cleaning brush 17 is disposed at the end of the fan blade of the fan 16, the rotating fan blade will drive the cleaning brush 17 to rotate. Because the edge of the cleaning brush 17 is tangent to the inner diameter of the pressure relief pipe 7, the cleaning brush 17 can clean the inner cavity of the pressure relief pipe 7, and the purpose of dust prevention is achieved. The fan 16 has twelve groups of blades in a circumferential array, so that the dust removing effect is better. Therefore, the hydraulic telescopic rod 13 is also started to perform telescopic movement at this time. Due to the telescopic operation of the hydraulic telescopic rod 13, the moving rod 14 on the right side is driven to move left and right. Since the slider 12 is connected to the rear surface of the moving rod 14, and the slider 12 can move only in the cavity of the groove 11, the moving direction of the moving rod 14 is limited, and only the horizontal movement in the left-right direction is achieved. The friction force of the groove 11 is small, so that the slider 12 can move in the groove 11 more stably, and the moving rod 14 moves more rapidly left and right. The front side of the displacement rod 14 extends through the slide groove 15 and into the inner cavity of the pressure relief tube 7, so that the front side part of the displacement rod 14 can only be displaced in the slide groove 15. A pin connection is provided between the travel bar 14 and the fan 16. Therefore, the moving rod 14 moves left and right to drive the fan 16 to move left and right in the inner cavity of the pressure relief pipe 7, so that the cleaning brush 17 is driven to move left and right to transversely clean the inner cavity of the pipeline of the pressure relief pipe 7, and the dust removal effect on the inner cavity of the pressure relief pipe 7 is achieved. The top of spring gland 2 is provided with dust cover 3, can protect spring gland 2 and valve body 1 part, avoids the interference of dust.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
