Abstract

The present invention relates to an automobile compressor exhaust valve plate applied in the automobile field, including a sliding valve plate assembly, etc. Under the combined action of the above-mentioned sliding valve plate assembly, etc., the present application changes the exhaust mode of the valve plate. When the air pressure is too high, the wear-resistant sliding valve plate will slide, causing the exhaust port to be connected for exhaust, so that the sliding valve plate assembly can be exhausted without bending, so it is not easy to break, and the reliability is high. In the exhaust process, the sliding valve plate assembly is not easy to vibrate, so no large noise will be generated, which greatly improves the practicality. In addition, through the setting of the magnetic repulsion exhaust aid assembly, when exhausting, the gas will blow the magnetic isolation thin cover upward, causing the connecting plate magnet to be exposed and repel the connecting plate magnet. The magnetic repulsion between the connecting plate magnet and the connecting plate magnet can not only make the exhaust port further open, but also hinder the wear-resistant sliding valve plate from resetting, thereby not only improving the exhaust efficiency but also improving the exhaust effect.

Description

Technical Field

[0001] The invention relates to an exhaust valve sheet, in particular to an automobile compressor exhaust valve sheet applied in the automobile field. Background Art

[0002] The automobile air-conditioning compressor is the heart of the automobile air-conditioning refrigeration system, which plays the role of compressing and transporting refrigerant vapor. The exhaust valve is an important component of the automobile compressor, which mainly plays the role of exhaust.

[0003] The exhaust valve plate in the prior art is usually made of elastic material. When the gas pressure is too high, the exhaust valve plate will bend under pressure, thereby opening the exhaust port for gas to be discharged. When the gas pressure is not enough to push open the exhaust valve plate, the exhaust valve plate will rebound and cover the exhaust port to make the exhaust port sealed.

[0004] Repeated bending, coupled with collision and impact each time the valve plate rebounds, makes the exhaust valve plate prone to breakage. In the exhaust process, the exhaust valve plate will generate a lot of noise due to vibration, making the exhaust valve plate in the prior art have defects such as easy breakage, poor reliability, and high noise. Therefore, we propose an exhaust valve plate for automobile compressors. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the exhaust valve sheet is not only easy to break but also makes a lot of noise.

[0006] In order to solve the above problems, the present invention provides an automobile compressor exhaust valve plate, comprising a sliding valve plate assembly and an easy-slip pressure plate assembly, the sliding valve plate assembly comprising a wear-resistant sliding valve plate and a supporting tube, the wear-resistant sliding valve plate is made of hard and wear-resistant material, the bottom end of the supporting tube is arranged in an opening shape, an elastic sealing membrane matching with it is sealed and fixedly connected on the inner wall of the supporting tube, a sliding linkage rod is penetrated through the middle part of the elastic sealing membrane, a fixed pulley is fixedly installed in the supporting tube, a sealing linkage rope is arranged on the fixed pulley, the sealing linkage rope is made of flexible sealing material, one end of the sealing linkage rope is fixedly connected with the sliding linkage rod, the sealing linkage rope penetrates the top outer wall of the supporting tube and is slidingly and sealingly connected thereto, the other end of the sealing linkage rope is fixedly connected with the wear-resistant sliding valve plate, and the connection between the sealing linkage rope and the wear-resistant sliding valve plate is a detachable fixed connection, the fixed pulley is located above the elastic sealing membrane, the easy-slip pressure plate assembly comprises an L-shaped supporting plate, and an elastic pull rope is fixedly connected between the wear-resistant sliding valve plate and the supporting plate.

[0007] In the above-mentioned automobile compressor exhaust valve plate, the wear-resistant sliding exhaust valve plate can be exhausted without bending, so it is not easy to break, has high reliability, and has low noise.

[0008] As a further improvement of the present application, a guide tube matching the sealing linkage rope is fixedly installed on the top end of the support tube, and the sealing linkage rope passes through the guide tube and is slidably and sealingly connected thereto.

[0009] As a further improvement of the present application, a guide rod is fixedly installed on the inner wall of the top end of the support cylinder, and a guide groove matching the guide rod is opened at the top end of the slide linkage rod. The guide rod and the guide groove are movably connected. The guide rod and the guide groove can play a guiding role to prevent the slide linkage rod from tilting, thereby facilitating the slide linkage rod to pull the wear-resistant slide valve plate.

[0010] As a further improvement of the present application, a connecting screw is fixedly installed on the support plate, an adjusting sleeve is sleeved on the outer wall of the connecting screw, the adjusting sleeve is threadedly connected to the connecting screw, a pressure roller is provided at the bottom end of the adjusting sleeve, and the adjusting sleeve is rotatably connected to the pressure roller through a bearing, which can not only prevent the wear-resistant sliding valve plate from being pushed upward by the gas, but also suppress the vibration of the wear-resistant sliding valve plate and reduce noise.

[0011] As a further improvement of the present application, connecting blocks are fixedly connected to the left and right sides of the pressing roller, and a guide slide rod is fixedly connected to the top of the connecting block. The guide slide rod passes through the support plate and is slidably connected thereto, so that when the adjusting sleeve rotates and drives the pressing roller to move downward, the pressing roller will not rotate, which is conducive to the sliding of the wear-resistant sliding valve plate.

[0012] As another improvement of the present application, it also includes a magnetic repulsion and drainage aid component, which includes a connecting sheet magnet and a connecting plate magnet. The connecting sheet magnet is fixedly mounted on the wear-resistant sliding valve plate, the top of the connecting plate magnet is fixedly connected to a connecting plate rod, and the outer movable cover of the connecting plate magnet is provided with a matching magnetic isolation thin cover.

[0013] As another improvement supplement of the present application, the connecting plate rod passes through the top outer wall of the magnetic isolation thin cover and is slidably connected thereto. The magnetic isolation thin cover is made of magnetic isolation material. The magnetic properties of the connecting plate magnet and the connecting sheet magnet near one end are the same, which can not only improve the exhaust efficiency, but also improve the exhaust effect.

[0014] As another improvement supplement of the present application, a plurality of lifting-assisting plates are fixedly connected to the outer wall of the magnetic isolation cover. The lifting-assisting plates are made of foam material. The lifting-assisting plates can increase the contact area between the gas and the magnetic isolation cover, which is beneficial for the gas to blow the magnetic isolation cover upward. The connecting plate rod is set to be square to prevent the magnetic isolation cover from rotating, which is beneficial for the alignment between the magnetic isolation cover and the connecting plate magnet.

[0015] To sum up, under the joint action of the sliding valve plate assembly and the easy-slip pressure plate assembly, the present application changes the exhaust mode of the valve plate. When the air pressure is too high, the wear-resistant sliding valve plate will slide, causing the exhaust port to be opened for exhaust, so that the sliding valve plate assembly can be exhausted without bending, so it is not easy to break, and has high reliability. In the exhaust process, the sliding valve plate assembly is not easy to vibrate, so it will not generate loud noise, which greatly improves practicality. Through the setting of the magnetic repulsion and exhaust assistance assembly, when exhausting, the gas will blow the magnetic isolation cover upward, causing the connecting plate magnet to be exposed and repel the connecting plate magnet. The magnetic repulsion between the connecting plate magnet and the connecting plate magnet can not only make the exhaust port further open, but also hinder the reset of the wear-resistant sliding valve plate, thereby not only improving the exhaust efficiency, but also improving the exhaust effect.

[0026] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0027] The first implementation method:

[0028] Figure 1-5 The invention discloses an exhaust valve plate for automobile compressor, comprising a sliding valve plate assembly and an easy-slip pressing plate assembly. The sliding valve plate assembly comprises a wear-resistant sliding valve plate 101 and a support tube 102. The wear-resistant sliding valve plate 101 is made of hard wear-resistant material. The bottom end of the support tube 102 is set to be open. An elastic sealing membrane 103 matching with the sliding valve plate is sealed and fixedly connected to the inner wall of the support tube 102. A sliding linkage rod 104 is penetrated through the middle of the elastic sealing membrane 103. A fixed pulley 105 is fixedly installed in the support tube 102. A sealing linkage rope 106 is set on the fixed pulley 105. The sealing linkage rope 106 is made of flexible sealing material. One end of the sealing linkage rope 106 is connected to the sliding linkage rod 104. Fixed connection, the sealing linkage rope 106 passes through the top outer wall of the support tube 102 and is slidably and sealedly connected thereto, the other end of the sealing linkage rope 106 is fixedly connected to the wear-resistant sliding valve plate 101, and the connection between the sealing linkage rope 106 and the wear-resistant sliding valve plate 101 is a detachable fixed connection, the fixed pulley 105 is located above the elastic sealing membrane 103, the easy-to-slide pressure plate assembly includes an L-shaped support plate 201, an elastic pull rope 109 is fixedly connected between the wear-resistant sliding valve plate 101 and the support plate 201, and a guide tube 107 matching the sealing linkage rope 106 is fixedly installed on the top of the support tube 102, and the sealing linkage rope 106 passes through the guide tube 107 and is slidably and sealedly connected thereto.

[0029] See also Figure 1-5, disconnect the connection between the sealing linkage rope 106 and the wear-resistant sliding valve disc 101, drill a hole matching the guide tube 107 on the flange, place the support tube 102 on the inner side of the flange, pass the guide tube 107 through the above hole, and seal the connection between the flange and the guide tube 107, then fix the support tube 102 on the inner side of the flange, place the wear-resistant sliding valve disc 101 on the outer side of the flange, reconnect the sealing linkage rope 106 with the wear-resistant sliding valve disc 101, and place the wear-resistant sliding valve disc 101 at the exhaust port, and then fix the support plate 201 on the outer side of the flange. When the gas pressure is too large, the elastic sealing membrane 103 will bulge upward and deform under the action of the gas pressure, causing the sliding linkage rope 106 to be deformed. The movable rod 104 moves upward, and the upward movement of the sliding linkage rod 104 will pull the wear-resistant sliding valve plate 101 through the sealing linkage rope 106, so that the exhaust port is opened, so that exhaust can be carried out. After the gas pressure is reduced, the elastic pull rope 109 will rebound, so that the wear-resistant sliding valve plate 101 will be reset and re-block the exhaust port. Therefore, the present application changes the exhaust method of the valve plate. When the air pressure is too high, the wear-resistant sliding valve plate 101 will slide, so that the exhaust port is opened for exhaust, so that the wear-resistant sliding valve plate 101 can be exhausted without bending, so it is not easy to break, and the reliability is high. In the exhaust process, the wear-resistant sliding valve plate 101 is not easy to vibrate, so it will not produce loud noise, which greatly improves the practicality.

[0030] See also Figure 4 A guide rod 108 is fixedly installed on the inner wall of the top end of the support cylinder 102, and a guide groove matching the guide rod 108 is opened at the top end of the slide linkage rod 104. The guide rod 108 is movably plugged into the guide groove. The guide rod 108 and the guide groove can play a guiding role to prevent the slide linkage rod 104 from tilting, which can facilitate the slide linkage rod 104 to pull the wear-resistant slide valve plate 101.

[0031] See also Figure 1-3A connecting screw 202 is fixedly installed on the support plate 201, and an adjusting sleeve 203 is sleeved on the outer wall of the connecting screw 202. The adjusting sleeve 203 is threadedly connected to the connecting screw 202. A pressing roller 204 is arranged at the bottom of the adjusting sleeve 203. The adjusting sleeve 203 is rotatably connected to the pressing roller 204 through a bearing. After fixing the support plate 201, the adjusting sleeve 203 is rotated to make the adjusting sleeve 203 rotate while driving the pressing roller 204 to move downward until the pressing roller 204 abuts against the top of the wear-resistant sliding valve plate 101. On the one hand, it can prevent the wear-resistant sliding valve plate 101 from being pushed upward by the gas, and on the other hand, it can inhibit the wear-resistant sliding valve plate 101 from being pushed upward by the gas. The vibration of the sliding valve plate 101 can be reduced, thereby reducing noise, and the friction between the wear-resistant sliding valve plate 101 and the pressure roller 204 is relatively small, so it will not cause too much obstruction to the sliding of the wear-resistant sliding valve plate 101, so that the exhaust can proceed smoothly, and the left and right sides of the pressure roller 204 are fixedly connected with connecting blocks 205, and the top of the connecting block 205 is fixedly connected with a guide slide bar 206, which passes through the support plate 201 and is slidably connected thereto, so that when the adjusting sleeve 203 rotates and drives the pressure roller 204 to move downward, the pressure roller 204 will not rotate, which is beneficial to the sliding of the wear-resistant sliding valve plate 101.

[0032] The second implementation method:

[0033] Figure 6-8 A vehicle compressor exhaust valve plate is shown. Different from the first embodiment, the exhaust valve plate in the present application also includes a magnetic repulsion exhaust assisting assembly, which includes a connecting plate magnet 301 and a connecting plate magnet 302. The connecting plate magnet 301 is fixedly installed on the wear-resistant sliding exhaust valve plate 101. The top of the connecting plate magnet 302 is fixedly connected to a connecting plate rod 303. The outer movable cover of the connecting plate magnet 302 is provided with a matching magnetic isolation thin cover 304. The connecting plate rod 303 penetrates the top outer wall of the magnetic isolation thin cover 304 and is slidably connected thereto. The magnetic isolation thin cover 304 is made of magnetic isolation material. The magnetic properties of the connecting plate magnet 302 and the connecting plate magnet 301 are the same at one end. When fixing the support plate 201, it is necessary to use The connecting plate magnet 302 and the magnetic isolation thin cover 304 are located above the exhaust port and aligned with the exhaust port. After the wear-resistant sliding valve plate 101 slides to make the exhaust port conductive, the gas flowing out of the exhaust port will blow the magnetic isolation thin cover 304 upward, causing the connecting plate magnet 302 to be exposed. At this time, under the action of the magnetic repulsion force between the connecting plate magnet 301 and the connecting plate magnet 302, the wear-resistant sliding valve plate 101 will further slide, causing the exhaust port to further open, thereby improving the exhaust efficiency. In addition, at this time, even if the elastic sealing membrane 103 rebounds to a certain extent due to the decrease in air pressure, the wear-resistant sliding valve plate 101 will not be completely reset, so that the exhaust can continue, thereby improving the exhaust effect.

[0034] See also Figure 7A plurality of lifting plates 305 are fixedly connected to the outer wall of the magnetic isolation cover 304. The lifting plates 305 are made of foam material and can increase the contact area between the gas and the magnetic isolation cover 304, which is beneficial for the gas to blow the magnetic isolation cover 304 upward. The connecting plate rod 303 is set to a square shape to prevent the magnetic isolation cover 304 from rotating, which is beneficial for the alignment between the magnetic isolation cover 304 and the connecting plate magnet 302.

[0035] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
