Description

Technical Field

[0001] The utility model relates to the technical field of cold and heat exchange equipment, in particular to a central air-conditioning cold and heat exchange control structure. Background Art

[0002] The four-way valve is a control valve with four oil ports. The four-way valve is an indispensable component in refrigeration equipment. Its working principle is that when the solenoid valve coil is in the power-off state, the high-pressure gas enters the capillary tube and then enters the piston chamber at the right end, so that the exhaust pipe is connected to the outdoor unit pipe, and the other two pipes are connected, forming a refrigeration cycle. When the solenoid valve coil is in the power-on state, the high-pressure gas enters the capillary tube and then enters the piston chamber at the left end, and the gas in the piston chamber at the right end is discharged. Due to the pressure difference at both ends of the piston, the piston and the main slide valve move to the right, so that the exhaust pipe is connected to the indoor unit pipe, and the other two pipes are connected, forming a heating cycle.

[0003] In the prior art, the hot and cold exchange control of the central air conditioner mainly relies on the four-way valve for switching. The four-way valve needs to withstand the impact of compressed gas for a long time in the equipment and needs to switch the connected pipes according to the user's hot and cold exchange control. Therefore, the four-way valve itself is subject to greater vibration when the central air conditioner is activated. The hot and cold exchange will also cause the four-way valve itself to vibrate. The four-way valve controls the hot and cold exchange and connects multiple pipes. The air tightness of the pipes needs to be guaranteed. Under the condition of continuous vibration, the air tightness of the pipes cannot be guaranteed, which can easily lead to loosening and falling off between the pipes and the four-way valve, causing leakage of high-temperature and high-pressure gas, damaging the central air conditioner, reducing the temperature control effect, and affecting the service life of the equipment. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a central air-conditioning cold and heat exchange control structure.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a central air-conditioning cold and heat exchange control structure, including a four-way valve body, a compressor connecting pipe is fixed on the top of the four-way valve body, a multi-stage valve is fixed on the bottom of the four-way valve body, a receiving plate is provided at both ends of the four-way valve body, a receiving valve groove is provided on the top of the receiving plate, the inner wall of the receiving valve groove is slidably connected with one end of the four-way valve body, a fixing groove is provided at the bottom of the receiving plate, a buffer spring is fixed on the inner wall of the fixing groove, one end of the buffer spring is fixed to a base plate, a fixing groove is provided on the top of the base plate, a resistance cylinder is fixed on the top of the base plate, and the top of the resistance cylinder is fixed to the bottom of the receiving plate. In the prior art, the cold and heat exchange control of the central air-conditioning mainly relies on the four-way valve for switching. Since the four-way valve needs to withstand the impact of compressed gas for a long time in the equipment and needs to switch the connected pipelines according to the user's cold and heat exchange control, it itself is subjected to greater vibration when the central air-conditioning is activated, and the cold and heat exchange will also cause the four-way valve itself to vibrate. The four-way valve controls the cold and heat exchange and connects multiple The air tightness of the pipeline cannot be guaranteed when it is constantly vibrated, which may easily lead to loosening and falling off between the pipeline and the four-way valve, causing leakage of high-temperature and high-pressure gas, damage to the central air conditioner, reduce the temperature control effect, and affect the service life of the equipment. In view of such problems, the utility model solves the problem by installing a connecting plate, so that when the equipment is vibrated by external force or vibrates itself, the connecting plate is vibrated and squeezes the buffer spring, and the buffer spring is vibrated and continuously stretches and contracts back and forth to buffer the direct impact of the vibration on the equipment, giving the equipment a buffer space. At the same time, the resistance cylinder is pulled by the buffer spring, and the airtight plate inside the resistance cylinder slides on the inner wall, and the internal air is continuously compressed, which increases the resistance and buffering of the airtight plate, hinders the rapid retraction and release of the buffer spring, reduces the reciprocating bounce of the buffer spring, and greatly reduces the vibration noise. The position change of the equipment affected by the vibration is also greatly reduced, so that the equipment and the pipeline are not easy to fall off, thereby achieving the effect of improving the stability of equipment use and increasing the service life of the equipment.

[0006] Preferably, the inner wall of the four-way valve body is rotatably connected to a plurality of rotating gears, the top of the rotating gear is provided with an inclined slot, the inner wall of the inclined slot is slidably connected to a sliding column, the surface of the sliding column is rotatably connected to a circular groove plate, one end of the circular groove plate is fixed with a sealing plate, and the inner wall of one end of the sealing plate is rotatably connected to a rotating column. In the prior art, the four-way valve is used as a main component for heat exchange, and generally connects and blocks different internal passages by whether or not electricity is turned on. The inner wall piston is closed at different positions under the influence of the electromagnet, and the equipment has extremely high requirements for air tightness. After the piston rubs against the inner wall for a long time, The electromagnet itself is subject to wear and tear, and its air tightness is easily affected. The electromagnet is prone to failure when working in a high temperature and high pressure environment for a long time, resulting in a decrease in the temperature regulation effect of the equipment, affecting the normal operation of the equipment. To solve this problem, the utility model adopts the method of installing a sealing plate to achieve a solution. When the user needs to adjust the temperature of the central air conditioner, the rotating gear on the inner wall of the closed multi-stage valve rotates, so that the bottom of the slide column is fixed along the inclined slide groove to one end close to the center of the rotating gear. At the same time, the sealing plate rotates with the rotating column as the axis, so that multiple sealing plates contact each other to seal the multi-stage valve, thereby achieving the effect of improving the air tightness of the equipment.

[0007] Preferably, a rubber pad is fixed to the bottom of the substrate. In the prior art, after the four-way valve body is fixed, it is easy to collide with the inner wall of the equipment due to vibration, making the equipment itself noisy, and the collision will continue to vibrate the equipment, affecting the tightness of the internal components of the equipment, resulting in a reduction in the service life of the equipment. To solve this problem, the utility model adopts a method of installing rubber pads to achieve a buffer between the four-way valve body and the inner wall of the equipment, thereby reducing noise pollution. Moreover, because the rubber pad can reduce the impact of the collision on the inner wall of the equipment, the vibration of the equipment is reduced, and the internal components of the equipment are prevented from loosening, thereby achieving the effect of increasing the service life of the equipment.

[0011] Preferably, the receiving plate is made of aluminum alloy to reduce deformation of the receiving plate and increase the service life of the component.

[0012] Beneficial Effects

[0013] 1. In the prior art, the hot and cold exchange control of the central air conditioner mainly relies on the four-way valve for switching. The four-way valve needs to withstand the impact of compressed gas for a long time in the equipment, and needs to switch the connected pipes according to the user's hot and cold exchange control. When the central air conditioner is activated, it is subject to greater vibration. The hot and cold exchange will also cause the four-way valve itself to vibrate. The four-way valve controls the hot and cold exchange and connects multiple pipes, and the air tightness of the pipes needs to be ensured. Under the condition of continuous vibration, the air tightness of the pipes cannot be guaranteed, which easily leads to loosening and falling off between the pipes and the four-way valve, causing leakage of high-temperature and high-pressure gas, damaging the central air conditioner, reducing the temperature control effect, and affecting the service life of the equipment. In view of such problems, the present utility model The type adopts the method of installing a connecting plate to solve the problem. When the equipment is vibrated by external force or generates vibration itself, the connecting plate is vibrated and squeezes the buffer spring. The buffer spring is vibrated and continuously stretches and contracts back and forth to buffer the direct impact of the vibration on the equipment, giving the equipment buffer space. At the same time, the resistance cylinder is pulled by the buffer spring, and the airtight plate inside the resistance cylinder slides on the inner wall. The internal air is continuously compressed, which increases the resistance and buffering of the airtight plate and hinders the rapid retraction and release of the buffer spring, reducing the reciprocating bounce of the buffer spring, thereby greatly reducing vibration noise and the position change of the equipment affected by vibration. It makes it difficult for the equipment to fall off from the pipeline, thereby improving the stability of equipment use and increasing the service life of the equipment.

[0014] 2. In the prior art, the four-way valve, as the main component for heat exchange, generally connects and blocks different internal passages by whether it is energized. The inner wall piston is closed at different positions under the influence of the electromagnet, and the equipment has extremely high requirements for air tightness. After the piston rubs against the inner wall for a long time, it is worn and the air tightness is easily affected. The electromagnet is prone to failure when working in a high temperature and high pressure environment for a long time, resulting in a decrease in the temperature regulation effect of the equipment and affecting the normal operation of the equipment. To solve such problems, the utility model solves them by installing sealing plates, so that when the user needs to adjust the temperature of the central air conditioner, the inner wall rotating gear of the multi-stage valve that needs to be closed rotates, so that the bottom of the slide column is fixed along the inclined slide groove to one end close to the center of the rotating gear, and at the same time, the sealing plate rotates with the rotating column as the axis, so that multiple sealing plates contact each other to seal the multi-stage valve, thereby achieving the effect of improving the air tightness of the equipment.

[0015] 3. In the prior art, after the four-way valve body is fixed, it is easy to collide with the inner wall of the equipment due to vibration, making the equipment itself noisy, and the collision will continue to vibrate the equipment, affecting the tightness of the internal components of the equipment, resulting in a reduction in the service life of the equipment. To solve this problem, the utility model adopts the method of installing rubber pads to achieve a buffer between the four-way valve body and the inner wall of the equipment, reducing noise pollution, and because the rubber pad can reduce the impact of the collision on the inner wall of the equipment, the vibration of the equipment is reduced, and the internal components of the equipment are prevented from loosening, thereby achieving the effect of increasing the service life of the equipment.

[0023] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment:

[0025] Reference Figure 1-4A central air conditioning cold and hot exchange control structure includes a four-way valve body 1, a compressor connecting pipe 101 is fixed on the top of the four-way valve body 1, a multi-stage valve 102 is fixed on the bottom of the four-way valve body 1, a receiving plate 2 is provided at both ends of the four-way valve body 1, a receiving valve groove 201 is opened on the top of the receiving plate 2, the inner wall of the receiving valve groove 201 is slidably connected with one end of the four-way valve body 1, a fixing groove 205 is opened at the bottom of the receiving plate 2, a buffer spring 202 is fixed on the inner wall of the fixing groove 205, one end of the buffer spring 202 is fixed to a base plate 204, and the base plate 204 A fixing groove 205 is provided on the top, a resistance cylinder 203 is fixed on the top of the base plate 204, and the top of the resistance cylinder 203 is fixed to the bottom of the receiving plate 2. The central air-conditioning hot and cold exchange control mainly relies on the four-way valve for switching. The four-way valve needs to withstand the impact of compressed gas for a long time in the equipment, and needs to switch the connected pipeline according to the user's hot and cold exchange control. When the central air-conditioning is activated, it is subjected to greater vibration. The hot and cold exchange will also cause the four-way valve itself to vibrate. The four-way valve controls the hot and cold exchange and connects multiple pipelines, which requires To ensure the air tightness of the pipeline, when it is constantly vibrated, the air tightness of the pipeline cannot be guaranteed, which may easily lead to loosening and falling off between the pipeline and the four-way valve, causing leakage of high-temperature and high-pressure gas, damaging the central air conditioner, reducing the temperature control effect, and affecting the service life of the equipment. The installation of the receiving plate 2 is used to solve the problem. When the equipment is vibrated by external force or vibrates itself, the receiving plate 2 is vibrated and squeezes the buffer spring 202. The buffer spring 202 is vibrated and continuously stretches and contracts back and forth to buffer the direct impact of the vibration on the equipment, giving the equipment a buffer space. At the same time, the resistance cylinder 203 is pulled by the buffer spring 202, and the airtight sheet inside the resistance cylinder 203 slides on the inner wall. The internal air is continuously compressed, which increases the resistance and buffering of the airtight sheet, hinders the rapid retraction and release of the buffer spring 202, reduces the reciprocating bounce of the buffer spring 202, and greatly reduces the vibration noise. The position change of the equipment affected by the vibration is also greatly reduced, so that the equipment and the pipeline are not easy to fall off, thereby improving the stability of equipment use and increasing the service life of the equipment. The receiving plate 2 is made of aluminum alloy to reduce the deformation of the receiving plate 2 and increase the service life of the components. The four corners of the base plate 204 are fixed with fixing rings 206, which are convenient for the staff to fix the cold and hot exchange control structure. The surface of the four-point valve body 1 is fixed with a signal device 103, which is convenient for the user to adjust the cold and hot conversion of the central air conditioner. The surface of the four-point valve body 1 is fixed with an indicator light 104, which is convenient for the staff to judge the operating status of the equipment during maintenance.

[0026] The inner wall of the four-way valve body 1 is rotatably connected to a plurality of rotating gears 3, and an inclined slide groove 301 is provided on the top of the rotating gear 3, and a sliding column 302 is slidably connected to the inner wall of the inclined slide groove 301, and a circular groove plate 303 is rotatably connected to the surface of the sliding column 302, and a sealing plate 304 is fixed at one end of the circular groove plate 303, and a rotating column 305 is rotatably connected to the inner wall of one end of the sealing plate 304. The four-way valve is the main component of the cold and heat exchange, and generally connects and blocks different internal passages by whether or not the power is turned on. The inner wall piston is closed at different positions under the influence of the electromagnet, and the equipment has extremely high requirements for air tightness. After the piston rubs against the inner wall for a long time, it is affected by the air tightness. Due to wear, the air tightness is easily affected. The electromagnet is prone to failure when working in a high temperature and high pressure environment for a long time, resulting in a decrease in the temperature regulation effect of the equipment and affecting the normal operation of the equipment. The problem is solved by installing a sealing plate 304. When the user needs to adjust the temperature of the central air conditioner, the rotating gear 3 on the inner wall of the closed multi-stage valve 102 rotates, so that the bottom of the sliding column 302 is fixed to the end close to the center of the rotating gear 3 along the inclined slide groove 301, and the sealing plate 304 rotates with the rotating column 305 as the axis, so that multiple sealing plates 304 contact each other to seal the multi-stage valve 102, thereby achieving the effect of improving the air tightness of the equipment. A rubber pad 207 is fixed at the bottom of the substrate 204. After the four-way valve body 1 is fixed, it is easy to collide with the inner wall of the equipment due to vibration, making the equipment itself noisy, and the collision will continue to vibrate the equipment, affecting the tightness of the internal components of the equipment, resulting in a reduction in the service life of the equipment. This is solved by installing a rubber pad 207, which achieves a buffer between the four-way valve body 1 and the inner wall of the equipment to reduce noise pollution. In addition, since the rubber pad 207 can reduce the impact of the collision on the inner wall of the equipment, the vibration of the equipment is reduced, and the internal components of the equipment are prevented from loosening, thereby achieving the effect of increasing the service life of the equipment.

[0027] The working principle of the utility model is as follows: when the equipment is subjected to external vibration or generates vibration itself, the receiving plate 2 is vibrated and squeezes the buffer spring 202. The buffer spring 202 is vibrated and continuously stretches and contracts back and forth to buffer the direct impact of the vibration on the equipment, giving the equipment a buffer space. At the same time, the resistance cylinder 203 is pulled by the buffer spring 202, and the airtight sheet inside the resistance cylinder 203 slides on the inner wall. The internal air is continuously compressed, which increases the resistance and buffering of the airtight sheet, hinders the rapid retraction and release of the buffer spring 202, reduces the reciprocating bounce of the buffer spring 202, and greatly reduces the vibration noise. The position change of the equipment affected by the vibration is also The friction between the equipment and the pipeline is greatly reduced, so that it is not easy to fall off. The rubber pad 207 buffers the space between the four-valve body 1 and the inner wall of the equipment to reduce noise pollution. Because the rubber pad 207 can reduce the impact of the collision on the inner wall of the equipment, the vibration of the equipment is reduced to avoid loosening of the internal components of the equipment. When the user needs to adjust the temperature of the central air conditioner, the inner wall rotating gear 3 of the closed multi-stage valve 102 rotates, so that the bottom of the sliding column 302 is fixed to one end close to the center of the rotating gear 3 along the inclined groove 301, and the sealing plate 304 rotates with the rotating column 305 as the axis, so that multiple sealing plates 304 contact each other to seal the multi-stage valve 102.
