Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile parts, in particular to a gravity valve for automobile heat dissipation. Background Art
[0002] As Figure 1 shown, a throttle ball and a throttle plug are arranged in the liquid inlet pipe of the gravity valve, and the joint plug is located at the inlet of the liquid inlet pipe. When assembling the existing gravity valve, in order to prevent the throttle plug from falling off from the liquid inlet pipe, usually after the throttle plug is inserted into the liquid inlet pipe, the throttle plug and the inner wall of the liquid inlet pipe are welded. However, since both the housing of the gravity valve and the throttle plug are plastic parts, the welding is difficult, the welding process is complex, resulting in high welding cost; redundant overflow materials are easily generated during the welding process, and the overflow materials generated by welding are easily dropped into the liquid inlet pipe to block the liquid inlet pipe, affecting the throttling effect of the throttle ball; the overflow materials generated by welding are easily introduced into the engine along with the antifreeze, resulting in non-compliance of the internal cleaning of the engine, thus causing damage to the internal parts of the engine, and further shortening the service life of the engine. Content of the Utility Model
[0003] To solve the problems caused by welding connection when assembling the throttle plug of the gravity valve, the utility model provides a gravity valve, which comprises a liquid inlet pipe and a throttle plug. An annular clamping groove is arranged on the inner wall of the liquid inlet end of the liquid inlet pipe, and an annular clamping protrusion is arranged on the outer wall of the throttle plug. When the throttle plug is assembled into the liquid inlet pipe, the annular clamping protrusion is clamped in the annular clamping groove and is in interference fit with the annular clamping groove.
[0004] In the gravity valve of the utility model, when the throttle plug is assembled to the liquid inlet end of the liquid inlet pipe, the annular clamping protrusion on the outer wall of the throttle plug is clamped in the annular clamping groove on the inner wall of the liquid inlet pipe and is connected with the annular clamping groove in an interference fit manner, without the need of welding connection, so that no welding overflow material is generated to affect the service life of the engine. In addition, when assembling the gravity valve of the utility model, the assembler only needs to press the throttle plug into the liquid inlet pipe and make the annular clamping protrusion on the throttle plug be clamped in the annular clamping groove on the inner wall of the liquid inlet pipe, and the assembly is simple and convenient, which can effectively reduce the production and assembly cost of the gravity valve of the utility model.
[0005] Preferably, both side walls of the annular groove are configured as clamping slopes, both end surfaces of the annular clamping protrusion are configured as raised slopes, and when the annular clamping protrusion is clamped into the annular groove, the raised slopes are aligned with the clamping slopes. In this way, when assembling the throttling plug, the assembler can use the clamping slopes on the side of the annular groove close to the liquid inlet port of the liquid inlet pipe and the raised slopes on the side of the annular clamping protrusion facing the throttling ball for guidance, so as to facilitate the buckle connection between the throttling plug and the liquid inlet pipe. Furthermore, a guide groove is provided on the inner wall of the liquid inlet pipe, and a throttling ball groove for installing a throttling ball is provided between the guide groove and the throttling plug; a drainage groove is provided on the inner wall of the connecting hole on the throttling plug, and the drainage groove and the guide groove are staggered. In this way, when in use, the position of the throttling ball in the throttling ball groove can be adjusted by the pressure difference on both sides of the throttling ball, thereby adjusting the flow rate of the liquid flowing into the liquid inlet pipe from the liquid inlet port of the liquid inlet pipe, that is, the connecting hole on the throttling plug; setting the guide groove and the drainage groove can prevent the throttling ball from completely blocking the liquid inlet pipe or the connecting hole, thereby affecting the liquid entering the liquid inlet pipe.
[0006] Preferably, the gravity valve includes a liquid outlet pipe, which is connected to the liquid inlet pipe and away from the throttling plug. In this way, when in use, the liquid outlet pipe can be used to connect with the liquid outlet fitting, so that the liquid entering the liquid inlet pipe is transported to the engine through the liquid outlet pipe and the liquid outlet fitting, avoiding the liquid in the liquid inlet pipe from directly transporting it to the engine and impacting the engine, or even causing damage to the parts in the engine. Furthermore, the liquid inlet pipe is vertically connected to the liquid outlet pipe. In this way, the liquid inlet pipe and the liquid outlet pipe are vertically connected, which can effectively alleviate the impact of the liquid transported from the liquid inlet pipe to the engine on the parts in the engine, thereby extending the service life of the engine.
[0007] Preferably, the gravity valve includes a positioning seat, which is close to the connection between the liquid inlet pipe and the liquid outlet pipe, and a positioning through hole is provided on the positioning seat. In this way, a positioning seat with a positioning through hole is provided near the connection between the liquid inlet pipe and the liquid outlet pipe, so that the gravity valve of the utility model can be fixed on the engine by using the positioning seat, so as to avoid the gravity valve of the utility model from shaking and shifting due to liquid impact during use, thereby affecting the connection stability between the gravity valve of the utility model and the matching accessories. Furthermore, the outer wall of the positioning through hole is connected to the outer wall of the liquid inlet pipe and the liquid outlet pipe through a connecting rib plate. In this way, the outer wall of the positioning through hole for fixing is connected to the outer wall of the liquid inlet pipe and the liquid outlet pipe through a connecting rib plate, which can effectively reduce the injection molding material of the positioning seat and improve the lightweight degree of the gravity valve of the utility model.

[0012] Next, in combination with Figures 1 to 4 , the gravity valve of the present utility model will be described in detail.
[0013] As Figures 1 to 4 shown, the gravity valve of the present utility model includes a liquid inlet pipe 1 and a throttle plug 2. An annular card slot 11 is provided on the inner wall of the liquid inlet end of the liquid inlet pipe 1, and an annular card projection 21 is provided on the outer wall of the throttle plug 2. When the throttle plug 2 is assembled into the liquid inlet pipe 1, the annular card projection 21 is clamped in the annular card slot 11 and is in interference fit with the annular card slot 11. In this way, in the gravity valve of the present utility model, when the throttle plug 2 is assembled to the liquid inlet end of the liquid inlet pipe 1, the annular card projection 21 on the outer wall of the throttle plug 2 is clamped in the annular card slot 11 on the inner wall of the liquid inlet pipe 1 and is connected with the annular card slot 11 in an interference fit manner, without the need for welding connection, and there will be no welding overflow material to affect the service life of the engine. In addition, when assembling the gravity valve of the present utility model, the assembler only needs to press the throttle plug 2 into the liquid inlet pipe 1 and make the annular card projection 21 on the throttle plug 2 be clamped in the annular card slot 11 on the inner wall of the liquid inlet pipe 1, and the assembly is simple and convenient, which can effectively reduce the production and assembly cost of the gravity valve of the present utility model. Preferably, both side walls of the annular card slot 11 are provided with clamping slopes 111, and both end faces of the annular card projection 21 are provided with protruding slopes 211. When the annular card projection 21 is clamped into the annular card slot 11, the protruding slope 211 is aligned with the clamping slope 111. In this way, when the assembler assembles the throttle plug 2, the clamping slope 111 on one side of the annular card slot 11 close to the liquid inlet port of the liquid inlet pipe 1 can be used to cooperate with the protruding slope 211 on the annular card projection 21 facing the throttle ball 3 for guiding, which is convenient for the snap connection between the throttle plug 2 and the liquid inlet pipe 1. Preferably, a diversion groove 12 is provided on the inner wall of the liquid inlet pipe 1, and a throttle ball groove 13 for installing a throttle ball 3 is provided between the diversion groove 12 and the throttle plug 2; a drainage groove 221 is provided on the inner wall of the communication hole 22 on the throttle plug 2, and the drainage groove 221 is arranged in a staggered manner with the diversion groove 12. In this way, during use, the position of the throttle ball 3 in the throttle ball groove 13 can be adjusted through the pressure difference on both sides of the throttle ball 3, so as to control the flow rate of the liquid flowing into the liquid inlet pipe 1 from the liquid inlet port of the liquid inlet pipe 1, that is, the communication hole 22 on the throttle plug 2; the diversion groove 12 and the drainage groove 221 are provided to prevent the throttle ball 3 from completely blocking the liquid inlet pipe 1 or the communication hole 22 and affecting the liquid from entering the liquid inlet pipe 1.
[0014] As shown Figures 1 to 4 in the figure, the gravity valve of the present utility model includes a liquid outlet pipe 4, which is communicated with the liquid inlet pipe 1 and is away from the throttling plug 2. In this way, during use, the liquid outlet pipe 4 can be used to communicate with the liquid outlet pair fitting (not shown in the figure), so that the liquid entering the liquid inlet pipe 1 is transported to the engine through the liquid outlet pipe 4 and the liquid outlet pair fitting, avoiding the impact on the engine when the liquid in the liquid inlet pipe 1 is directly transported to the engine, and even causing damage to the components in the engine. Preferably, the liquid inlet pipe 1 is vertically communicated with the liquid outlet pipe 4. In this way, the liquid inlet pipe 1 and the liquid outlet pipe 4 are vertically communicated, which can effectively relieve the impact of the liquid transported from the liquid inlet pipe 1 to the components in the engine and extend the service life of the engine.
[0015] As shown Figures 1 to 4 in the figure, the gravity valve of the present utility model includes a positioning seat 5, which is close to the connecting part of the liquid inlet pipe 1 and the liquid outlet pipe 4, and a positioning through hole 51 is provided on the positioning seat 5. In this way, a positioning seat 5 with a positioning through hole 51 is provided close to the connecting part of the liquid inlet pipe 1 and the liquid outlet pipe 4, so as to facilitate the fixing of the gravity valve of the present utility model on the engine by using the positioning seat 5, avoiding the shaking and displacement of the gravity valve of the present utility model due to liquid impact during use, and affecting the connection stability between the gravity valve of the present utility model and the pair fitting. Preferably, the outer wall of the positioning through hole 51 is connected to the outer walls of the liquid inlet pipe 1 and the liquid outlet pipe 4 through connecting rib plates 52. In this way, the outer wall of the positioning through hole 51 for fixing is connected to the outer walls of the liquid inlet pipe 1 and the liquid outlet pipe 4 through connecting rib plates 52, which can effectively reduce the injection molding material of the positioning seat 5 and improve the lightweight degree of the gravity valve of the present utility model.
