Description

Technical Field

[0001] The utility model relates to the technical field of pressure relief valves, and specifically to an exhaust pressure relief valve. Background Art

[0002] An exhaust pressure relief valve, officially named "bypass valve", plays an important role in a turbocharging system. It is divided into an intake pressure relief valve and an exhaust pressure relief valve, corresponding to the intake pressure housing and the exhaust pressure housing of the turbocharger respectively. In the prior art, during the exhaust process, a spring is used to control the upward movement of a filter element. However, when the filter element is reset later, since the filter element moves downward automatically, it is likely that the gas emission is not sufficient and it is inconvenient to use.

[0003] For example, the patent application number is CN201520274441.0. This utility model discloses an automatic exhaust pressure relief valve. During specific use, gas can be discharged through a pressure relief channel. After the gas in the valve body and the equipment is discharged, the valve core will be pushed upward, compressing the spring, and then the valve core blocks the pressure relief channel and the valve closes. This automatic exhaust pressure relief valve of the utility model can achieve automatic opening and closing and can ensure that there is no gas in the valve body. However, when the filter element is reset later, since the filter element moves downward automatically, it is likely that the gas emission is not sufficient and it is inconvenient to use.

[0004] For example, the patent application number is CN201710364037.6. This invention provides an exhaust pressure relief valve, including: a valve base; a valve body cooperating with the valve base, and the valve body and the valve base form a cavity in combination; a valve seat and a valve cover arranged in the cavity, the valve seat and the valve cover are closely attached to form an accommodation space; a valve ball arranged in the accommodation space, and the up-and-down movement height of the valve ball is less than or equal to 0.5 mm. This invention cancels the sealing gasket between the valve seat and the valve cover, reduces the falling height of the valve ball, thereby accelerating the falling speed of the valve ball and avoiding the gas backflow. However, when the filter element is reset later, since the filter element moves downward automatically, it is likely that the gas emission is not sufficient and it is inconvenient to use. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides an exhaust pressure relief valve, which solves the problem that when the filter element is reset later, since the filter element moves downward automatically, it is likely that the gas emission is not sufficient and it is inconvenient to use.

[0014] Beneficial effects

[0015] The utility model provides an exhaust pressure relief valve. Compared with the prior art, the following beneficial effects are achieved:

[0016] 1. For this channel overflow sand addition device, when the horizontal plate moves upward, the distance between the round block and the inclined plate will be reduced and they will come into contact. As the round block continues to move upward, the clamping plate will merge with the horizontal groove, which will not affect the upward movement of the round block. Moreover, through the inclined plate, the round block and the rubber pad can be moved, enabling the positive magnet and the negative magnet to come into contact, improving the stability after the movement of the rubber pad. The rubber pad can increase friction, so that the resistance of downward movement is increased through the rubber belt, allowing the gas in the valve body to be fully discharged and preventing the problem of insufficient exhaust.

[0017] 2. After the rubber pad of this channel overflow sand addition device moves downward for a period of time, it will come into contact with the push plate. Since the push plate is semi-circular, the rubber pad is separated from the inner wall of the valve body, facilitating the subsequent upward movement of the horizontal plate.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-3, the present utility model provides a technical solution: an exhaust pressure relief valve, which includes a valve body 1. A motion mechanism 2 is arranged inside the valve body 1. Openings 3 are arranged at both ends of the valve body 1. A blocking plate 4 is arranged at the bottom of the motion mechanism 2. Fixing plates 5 are arranged on both sides of the blocking plate 4. One end of the fixing plate 5 is fixedly connected to the inner wall of the valve body 1, and the other end of the fixing plate 5 is in contact with the blocking plate 4.

[0025] The motion mechanism 2 includes a lifting rod 201. A cross plate 202 is fixedly arranged on the outer side of the bottom end of the lifting rod 201. Chute grooves 203 are arranged on the top surfaces of both ends of the cross plate 202. A positive magnet 204 is fixedly arranged inside one end of the chute groove 203. A negative magnet 205 is arranged inside the other end of the chute groove 203. Motion plates 206 are arranged on both sides of the lifting rod 201. The motion plates 206 are fixedly connected to the negative magnets 205. A rubber pad 207 is arranged at one end of the motion plate 206. A round block 208 is fixedly arranged at the other end of the motion plate 206, and the round block 208 is in contact with the cross plate 202. An inclined plate 209 is arranged above the lifting rod 201.

[0026] The lifting rod 201 is fixedly connected to the blocking plate 4. A guiding rod 210 is arranged at the top end of the lifting rod 201. The bottom end of the guiding rod 210 extends into the inside of the lifting rod 201.

[0027] The top end of the guiding rod 210 is fixedly connected to the inner wall of the top end of the valve body 1. A connecting spring 211 is arranged on the outer side of the guiding rod 210.

[0028] Clamping plates 212 are arranged on both sides of the connecting spring 211. The clamping plates 212 are fixedly connected to the inclined plate 209. A falling prevention rod 213 is arranged at the top of the inclined plate 209. A horizontal groove 214 is arranged on the top surface of the cross plate 202. The horizontal groove 214 and the clamping plate 212 are vertically collinear.

[0029] Please refer to Figure 1 and 4 , the horizontal groove 214 is adapted to the clamping plate 212. A pushing plate 215 is arranged on the top of the rubber pad 207. The cross-sectional shape of the pushing plate 215 is semi-circular. The negative magnet 205 is movably connected to the chute groove 203. The number of the inclined plates 209 is two, and the two inclined plates 209 are located on both sides of the guiding rod 210.

[0030] During operation, when gas enters the valve body 1 through the opening 3, it causes the baffle 4 inside the valve body 1 to move upward, separating the baffle 4 from the fixing plate 5, thus completing the gas discharge. Moreover, as the baffle 4 moves upward, it pushes the upper lifting rod 201 upward and causes the cross plate 202 to move upward simultaneously. Since the lifting rod 201 contacts the guiding rod 210, the lifting rod 201 moves upward along the guiding rod 210, squeezing the connecting spring 211 above the lifting rod 201 and deforming the connecting spring 211. Through the upward movement of the cross plate 202, the round block 208 moves upward, reducing the distances between both the round block 208 and the cross plate 202 and the clamping plate 212. Because the clamping plate 212 and the transverse groove 214 are vertically collinear and the clamping plate 212 is adapted to the transverse groove 214, finally the transverse groove 214 on the surface of the cross plate 202 merges with the clamping plate 212, enabling the cross plate 202 to continue moving upward. As a result, the round block 208 on the cross plate 202 gradually contacts the inclined plate 209. Through the inclined plate 209, the continuously upward moving round block 208 can be made to move, causing the round block 208 to move obliquely and increasing the distance between the two round blocks 208. When the round block 208 moves, it pushes the moving plate 206 to move, and the negative magnet 205 fixedly connected to the moving plate 206 moves simultaneously. Since the negative magnet 205 is movably connected to the sliding groove 203, the negative magnet 205 moves along the sliding groove 203. Finally, the positive magnet 204 can be made to contact the negative magnet 205. Because the positive magnet 204 and the negative magnet 205 attract each other, the positive magnet 204 and the negative magnet 205 are adsorbed together, enhancing the stability of the moving plate 206 after movement. Moreover, the movement of the moving plate 206 causes the rubber pad 207 to move simultaneously, bringing the rubber pad 207 into contact with the inner wall of the valve body 1, facilitating subsequent operations. When the rubber pad 207 contacts the valve body 1, the rubber pad 207 can increase friction, thereby increasing the resistance to downward movement through the rubber band, enabling the gas in the valve body 1 to be fully discharged and preventing the problem of insufficient exhaust. When the rubber pad 207 moves downward, it contacts the push plate 215. Since the push plate 215 is semi-circular, the rubber pad 207 is separated from the inner wall of the valve body 1.
