Description

Technical Field

[0001] The present invention relates to the technical field related to pressure relief valves, and in particular to a pressure relief valve for a worm gear supercharged engine. Background Art

[0002] The engine's pressure relief valve can automatically open and close according to the working pressure of the equipment. When the internal pressure of the equipment exceeds the design requirements, the pressure relief valve automatically opens to discharge excess gas in the engine, so that the pressure inside the equipment is maintained within a safe range, ensuring that the equipment can operate safely and stably.

[0003] The existing engine pressure relief valve generally forms a sealing structure through the sealing body of the valve core and the connected exhaust pipe. When the pressure exceeds the pressure relief pressure value, the valve core can be pushed to move, so that a gap appears between the sealing body and the exhaust pipe, allowing the gas to be discharged and achieving pressure relief. Since the ventilation area between the sealing body of the valve core and the connected exhaust pipe is fixed, it is difficult to quickly reduce the equipment pressure when discharging high-pressure gas, which is relatively inconvenient.

[0015] Technical effects and advantages of the present invention: The present invention utilizes the arrangement mode of the auxiliary pressure relief mechanism, the filtering mechanism and the installation mechanism in coordination. When the high-pressure gas is discharged, the auxiliary pressure relief mechanism can further open the pressure relief channel inside the valve body after the sealing body is opened for pressure relief, thereby assisting the pressure relief, so that the high-pressure gas can be discharged quickly, the exhaust speed is accelerated, the pressure relief effect of the pressure relief valve on the engine is effectively improved, and the protection ability of the engine is enhanced. The filtering mechanism can filter the gas during the auxiliary pressure relief to ensure that the discharged gas will not pollute the environment. At the same time, the installation mechanism can install the valve body and the filter plate in the filtering mechanism at the same time, which is convenient for use. The present invention utilizes the arrangement mode of matching the guide rod, the rotating rod, the extrusion sleeve, the first compression spring, the pressure relief assembly, the positioning rod and the limit block. The guide rod can not only guide the moving valve core, but also drive the guide rod to rotate through the rotating rod, so that the extrusion sleeve adjusts the compression degree of the first compression spring, thereby adjusting the pressure relief pressure value of the entire valve body, so that the use range of the entire valve body is wider. At the same time, the pressure relief assembly can also maintain the sealing effect on the sealing body when there is no high-pressure gas flowing, and can also open the sealing body when there is high-pressure gas flowing, so that a part of the high-pressure gas can flow out from the guide rod, and the auxiliary pressure relief pipeline discharges the high-pressure gas, which speeds up the exhaust speed and effectively improves the pressure relief effect of the pressure relief valve on the engine. The present invention utilizes a setting mode in which a fixing sleeve, an annular sleeve, a sealing plug, a sleeve, an extrusion plate, a connecting rod, a second compression spring, a fixing rod, a telescopic rod, a first magnet, a second magnet and an extrusion rod cooperate with each other. By utilizing the elastic force of the second compression spring on the extrusion plate, the sealing plug on the connecting rod can slide and intersect with the annular sleeve, thereby sealing the air inlet groove. When there is no gas flow, the first magnet and the second magnet are attracted to each other, and the telescopic rod can limit the connecting rod to prevent the sealing plug from failing to ensure the sealing effect of the sealing body when there is no high-pressure gas discharge. When there is high-pressure gas discharge, the sealing body moves upward with the moving valve core. At this time, the extrusion rod will squeeze the telescopic rod with an inclined surface, so that the telescopic rod is displaced, and the sliding hole provided on the telescopic rod is squeezed to the top of the connecting rod. At this time, the sealing plug can be opened under the push of the high-pressure gas, and the high-pressure gas flows to the inside of the guide rod through the fixing sleeve and is discharged through the filtering mechanism, thereby realizing auxiliary discharge of the high-pressure gas and accelerating the exhaust speed. The present invention utilizes the arrangement mode that the filtering mechanism and the mounting mechanism cooperate, utilizes the first clamping assembly to mount and fix the entire valve body and the pressure relief pipe, utilizes the second clamping assembly to enable the filter plate to be installed by clockwise rotating the rotating ring so that the L-shaped rod in the second clamping assembly is inserted into the C-shaped groove provided on the filter plate, and utilizes the elastic force of the third compression spring and the fourth compression spring so that the filter plate can be clamped into the inner depth of the C-shaped groove after being pressed into the interior of the fixing plate, thereby realizing the installation and fixation of the filter plate, and at the same time, after the filter plate is installed and fixed, the positioning rod can be positioned by the limiting of the ejection rod to prevent the rotating rod from rotating accidentally, thereby maintaining the stability of the entire device, and when disassembling, it is only necessary to press the filter plate and rotate the rotating ring clockwise so that the L-shaped rod can slide from the depth of the C-shaped groove to the opening, and then it can be ejected under the elastic force of the ejection rod, thereby realizing the disassembly of the filter plate, and when the rotating ring is rotated counterclockwise, the sliding groove and the extrusion groove can be used to squeeze the slide plate and the pull rod, thereby realizing the disassembly of the entire valve body, which is convenient for use.

[0035] Furthermore, the bottom end of the valve body 2 is fixedly connected to a second sealing ring 10 that contacts the inner wall of the pressure relief pipe 1, and the bottom end of the sealing body 5 is fixedly connected to a third sealing ring 11 that blocks the flow of gas. The second sealing ring 10 can keep the valve body 2 in a sealed state after being installed on the pressure relief pipe 1, and the third sealing ring 11 can ensure that the sealing body 5 and the pressure relief pipe 1 are in a sealed state when there is no high-pressure gas flowing.

[0036] Working principle of the present invention: when installing between the valve body 2 and the pressure relief pipe 1, by rotating the rotating ring 81 counterclockwise, the sliding groove and the extrusion groove are used to squeeze the slide plate 853 and the pull rod 852, so that the pull rod 852 can pull the clamping rod 851 to be stored in the clamping groove provided in the valve body 2. At this time, the valve body 2 can be placed in the required installation position of the pressure relief pipe 1, and by rotating, the rotating ring 81 can be reset under the elastic force of the fourth compression spring 84, so that the clamping rod 851 pops out of the valve body 2 again and is clamped with the clamping hole to achieve the installation of the valve body 2. At this time, the rotating rod 62 can be rotated, and the rotating rod 62 can drive the guide rod 61 to rotate when rotating, which can The extrusion sleeve 63 can be driven to slide inside the static valve core 3, so that the compression degree of the first compression spring 64 can be adjusted, so that the pressure relief pressure value of the entire valve body 2 can be adjusted. After adjusting to the value required by the engine, the rotating ring 81 can be rotated clockwise, so that the L-shaped rod 862 can be driven to rotate clockwise through the rotating plate 861, so that the filter plate 72 can be pressed into the inside of the fixed plate 71, and the C-shaped groove opening opened by the filter plate 72 is interlaced with the L-shaped rod 862. At this time, the rotating ring 81 is reversed so that the L-shaped rod 862 can slide to the depth of the C-shaped groove under the elastic force of the third compression spring 75, so that the filter plate 72 can be fixed and installed. At this time, the entire valve body 2 is installed; When in use, when there is no high-pressure gas discharged, the first magnet 6510 and the second magnet 6511 are attracted to each other, and the telescopic rod 659 can limit the connecting rod 656, so that the sealing plug 653 cannot move, thereby ensuring the sealing effect of the sealing body 5 on the pressure relief pipe 1. When high-pressure gas is discharged, the sealing body 5 moves up with the moving valve core 4. At this time, the squeezing rod 6512 will squeeze the telescopic rod 659 with an inclined surface, so that the telescopic rod 659 is displaced, and the sliding hole opened thereon is squeezed to the top of the connecting rod 656. At this time, the sealing plug 653 can be opened under the push of the high-pressure gas, and the high-pressure gas flows to the inside of the guide rod 61 through the fixing sleeve 651, and is discharged after being filtered by the filter plate 72, thereby realizing auxiliary discharge of high-pressure gas, accelerating the exhaust speed, improving the pressure relief effect of the pressure relief valve on the engine, and enhancing the protection ability of the engine.
