Description

Technical Field

[0001] This utility model relates to the field of temperature control valve technology, and more specifically, to a temperature control valve for air compressors. Background Technology

[0002] Thermostatic valves are key components in air compressors (referred to as air compressors) used to automatically regulate oil temperature. By controlling the flow path of lubricating oil, they ensure that the air compressor operates within the optimal temperature range, thereby ensuring equipment efficiency, extending service life, and reducing maintenance costs.

[0003] Existing temperature control valves for screw air compressors have the problem that, in traditional self-operated temperature control valves, the size of the flow orifice on the valve core remains constant when adjusting the flow rate. If the flow rate needs to be changed while keeping the temperature constant, a valve core with a different orifice diameter needs to be replaced. This operation is time-consuming, labor-intensive, and costly.

[0004] A search revealed that Chinese patent CN210218128U discloses a temperature control valve for screw air compressors. By designing a rotating mechanism, the opening size of the first and second through holes can be changed by turning the knob, thereby achieving the purpose of changing the flow rate without replacing the valve core. The operation is simple, there is no need to replace the valve core, and it is economical.

[0005] In actual use, the aforementioned temperature control valve for screw air compressors is not convenient for responding and adjusting to subtle temperature changes in a timely and accurate manner within the air compressor system. This can lead to overheating or overcooling of the system, reduce the performance of the lubricating oil, affect the lubrication effect of the equipment, increase the risk of equipment failure, and shorten the service life of the equipment. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a temperature control valve for air compressors to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A temperature control valve for an air compressor includes a valve body, a valve cover at the bottom of the valve body, multiple bolts threaded to the outside of the valve cover, spring washers on the outside of the bolts, an inlet port inside the valve cover, a first outlet port at the top of the valve body, a second outlet port on one side of the valve body, a valve core support inside the valve body, an adjusting mechanism inside the valve body, and a sealing assembly inside the valve body. The adjusting mechanism includes an O-ring installed inside the valve body, a valve core installed inside the valve core support, the O-ring being made of fluororubber, a valve core cover installed outside the valve core, a lip-shaped toothed ring on the outside of the valve core cover, a first cavity inside the valve body, and a second cavity inside the valve body.

[0009] By adopting the above technical solution, the movement path of the valve core cover can be automatically adjusted according to the temperature of the temperature bulb, thereby enabling the fluid to be rationally distributed according to the actual temperature requirements.

[0010] As a further description of the above technical solution: the sealing assembly includes a first sealing ring, which is fixedly connected to the outer side of the valve core cover. A retaining ring is fixedly connected to the top of the valve core cover. A slot is provided inside the valve body, and the slot is inserted into the outer side of the retaining ring. A third sealing ring is fixedly connected to the outer side of the valve core cover. The first sealing ring and the second sealing ring are both made of rubber. A second sealing ring is fixedly connected inside the valve body. The outer side of the first sealing ring and the inner side of the second sealing ring are adapted to each other. A fourth sealing ring is fixedly connected to the top of the valve core bracket. The inner side of the fourth sealing ring and the outer side of the third sealing ring are adapted to each other. Both the fourth sealing ring and the third sealing ring are made of rubber.

[0011] By adopting the above technical solution, an effective sealing environment can be provided at the connection between the valve core cover and the first and second cavities under different conditions, which can prevent internal liquid from leaking out from these gaps, thereby maintaining the normal operation of the valve body.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By setting an adjustment mechanism, compared with the existing technology, the valve core cover can move according to the different temperatures of the temperature bulb, so that the liquid can automatically adjust the liquid flow direction under different temperature conditions, so that the liquid runs according to the preset logic, achieves precise temperature control, and can reasonably distribute fluid according to actual temperature requirements, avoiding overheating or overcooling of the system, thereby improving the stability and reliability of the entire system.

[0014] 2. By setting a sealing component, compared with the prior art, the first sealing ring and the second sealing ring can be bonded together to provide a sealing effect at the connection between the valve core cover and the first cavity, and the fourth sealing ring and the third sealing ring can be bonded together to provide sealing conditions at the connection between the valve core cover and the second cavity. This allows the liquid to effectively fill the gaps between the valve core cover connections when it flows along a specific path, preventing the internal liquid from leaking out of these gaps, thereby maintaining the normal operation of the valve body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The embodiments disclosed in this application are as follows: Figure 1-6The temperature control valve for an air compressor shown includes a valve body 1, a valve cover 2 at the bottom of the valve body 1, multiple bolts 19 threadedly connected to the outside of the valve cover 2, and spring washers 18 on the outside of the bolts 19. An inlet 3 is provided inside the valve cover 2, a first outlet 4 is provided at the top of the valve body 1, and a second outlet 5 is provided on one side of the valve body 1. A valve core support 6 is installed inside the valve body 1, as is an adjusting mechanism. A sealing assembly is also installed inside the valve body 1. The adjusting mechanism includes an O-ring 7, which is installed inside the valve body 1 and is made of fluororubber. A valve core 10 is installed inside the valve core support 6, and a valve core cover 11 is installed outside the valve core 10. A lip-shaped toothed ring 8 is provided on the outside of the valve core cover 11. A first cavity 9 and a second cavity 20 are provided inside the valve body 1. By adjusting the temperature of the temperature bulb, the valve core cover 11 can move under the action of the valve core 10. When the temperature is low... When the temperature of the heating element is at its initial opening temperature, the liquid flows out from the second outlet 5 through the first cavity 9. When the temperature is lower than the temperature controlled by the heating element, the liquid enters from the inlet 3 and flows out from the second outlet 5 and the first outlet 4 through the first cavity 9 and the second cavity 20, respectively. When the temperature is higher than the temperature at which the heating element is fully open, the liquid can flow to the cooler through the second cavity 20 from the first outlet 4. This allows the liquid to automatically adjust its flow direction under different temperature conditions, rationally distribute the fluid, and avoid overheating or overcooling of the system, thereby improving the stability and reliability of the entire system. Furthermore, the lip-shaped toothed ring 8 and the valve body 1 are interference-fitted, which can improve the pressure resistance.

[0024] Reference Figure 2 , 5 As shown in Figure 6, the sealing assembly includes a first sealing ring 12, which is fixedly connected to the outer side of the valve core cover 11. A retaining ring 13 is fixedly connected to the top of the valve core cover 11. A slot 14 is provided inside the valve body 1, and the slot 14 is inserted into the outer side of the retaining ring 13. A third sealing ring 16 is fixedly connected to the outer side of the valve core cover 11. The first sealing ring 12 and the second sealing ring 15 are both made of rubber. The second sealing ring 15 is fixedly connected inside the valve body 1. The outer side of the first sealing ring 12 is adapted to the inner side of the second sealing ring 15. A fourth sealing ring 17 is fixedly connected to the top of the valve core bracket 6. The inner side of the fourth sealing ring 17 is adapted to the outer side of the third sealing ring 16. Both the fourth sealing ring 17 and the third sealing ring 16 are made of rubber. By adapting the first sealing ring 12 to the second sealing ring 15, an effective sealing effect can be provided at the connection between the valve core cover 11 and the first cavity 9. By adapting the third sealing ring 16 to the fourth sealing ring 17, a sealing effect can be provided at the connection between the valve core cover 11 and the second cavity 20. This allows the liquid to effectively fill the gaps between the valve core cover 11 connections when it flows along a specific path, thereby maintaining the normal operation of the valve body 1.

[0025] Working principle of this utility model: This utility model designs a temperature control valve for air compressors, the specific structure of which is shown in the attached instruction manual. Figure 1-6 As shown, in this technical solution, through the cooperation between various structures, when the air compressor is in use, liquid enters the valve body 1 from the inlet 3. When the temperature is lower than the starting temperature of the temperature bulb, the valve core 10 is fixed, and the third sealing ring 16 and the fourth sealing ring 17 are in a close fit. By utilizing the fit between the outer side of the third sealing ring 16 and the inner side of the fourth sealing ring 17, the contact between the third sealing ring 16 and the fourth sealing ring 17 can provide a sealing condition at the connection between the valve core cover 11 and the second cavity 20. At this time, the liquid will pass through the valve core cover 11 and enter the first cavity 9. The inclined surface of the first cavity 9 can increase the flow rate of the liquid, so the liquid will flow out from the second outlet 5 after passing through the first cavity 9.

[0026] When the temperature is lower than the temperature controlled by the temperature bulb, the spring on the valve core 10 can drive the valve core cover 11 to move, thereby causing the valve core cover 11 to separate the third sealing ring 16 and the fourth sealing ring 17. The top of the valve core cover 11 is in contact with the inner side of the valve body 1, so that the first cavity 9 and the second cavity 20 will have gaps with the valve core cover 11, so that when the liquid enters from the inlet 3, it can flow out from the second outlet 5 and the first outlet 4 respectively through the first cavity 9 and the second cavity 20.

[0027] When the temperature is higher than the temperature at which the thermostat is fully open, the valve core 10 can push the valve core cover 11 upward to contact the inner side of the valve body 1, so that the valve core cover 11 can drive the insert ring 13 to insert into the slot 14, and can drive the inner sides of the first sealing ring 12 and the second sealing ring 15 to fit together. By adapting the inner sides of the first sealing ring 12 and the second sealing ring 15, the first sealing ring 12 and the second sealing ring 15 can provide a seal at the connection between the valve core cover 11 and the first cavity 9, so that when the liquid enters the valve body 1 through the liquid inlet 3, it can flow to the cooler through the second cavity 20 from the first liquid outlet 4.

Other structures can be referred to with ordinary design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
