Description

Technical Field

[0001] The utility model relates to the technical field of accelerating valve bodies, in particular to a high-temperature resistant accelerating valve body. Background Art

[0002] The accelerator valve is also called the relay valve. The relay valve is part of the automobile air brake system. In the brake system of a truck, the relay valve shortens the reaction time and the pressure build-up time. The air inlet of the relay valve is connected to the air reservoir, and the air outlet is connected to the brake air chamber. When the brake pedal is pressed, the output air pressure of the brake valve is used as the control pressure input of the relay valve. Under the control pressure, the air inlet valve is pushed open, so the compressed air enters the brake air chamber directly from the air reservoir through the air inlet without flowing through the brake valve. This greatly shortens the inflation line of the brake air chamber and accelerates the inflation process of the air chamber.

[0003] After searching, the applicant found that a Chinese patent disclosed "an acceleration valve for a hydraulic system", and its publication (announcement) number is "CN201396331Y". This patent mainly connects the acceleration valve to the hydraulic system through the connecting pipe of the acceleration valve, rotates the adjusting head to cause the valve stem to displace in the valve cylinder, and changes the throttle opening position through the displacement of the valve stem, thereby adjusting the engine output power, and finally realizing stepless speed regulation of the hydraulic system. However, it is impossible to dissipate the high temperature generated when the acceleration valve is used. The acceleration valve itself is prone to high temperature when in use, and the external air will also heat up accordingly, causing the acceleration valve to be in a high temperature state for a long time, reducing its service life. For this reason, we propose a high temperature resistant acceleration valve body. Utility Model Content

[0027] In one embodiment of the present utility model: the adaption groove 52 is used for seamless installation of the heat conducting sheet 51 and the heat dissipation frame 54 with the valve body assembly 1 , and the bottom of the heat conducting sheet 51 is fixedly mounted on the upper surface of the valve body assembly 1 .

[0028] In one embodiment of the utility model: the bottom of the heat dissipation frame 54 is fixedly mounted on the upper surface of the heat conductive sheet 51 near the edge, the upper surface of the heat dissipation frame 54 is provided with dustproof and heat dissipation holes, the circulation pump 55 is fixedly mounted on the surface of the heat dissipation frame 54 near one side of the adapter groove 52, and the refrigerator 57 is fixedly mounted on the surface of the heat dissipation frame 54 near the other side of the adapter groove 52.

[0029] In one embodiment of the present invention, one end of the connecting conduit 56 is plugged into the water outlet pipe of the circulation pump 55 , and the other end of the connecting conduit 56 is plugged into the water inlet pipe of the refrigerator 57 .

[0030] In one embodiment of the utility model: a connecting mechanism 6 is provided on the left side of the valve body assembly 1, the connecting mechanism 6 includes a connecting frame 64 and a mounting groove 61, the right side surface of the connecting frame 64 is an arc shape for adapting to the valve body assembly 1, and threaded holes 65 are penetrated through the upper surface of the connecting frame 64 near the two sides.

[0031] In one embodiment of the utility model: the threaded hole 65 is used to connect with the bolts on the valve body assembly 1, and expansion grooves 66 are provided on both sides of the connecting frame 64. The inner wall of the expansion groove 66 is fixedly installed with a limit spring 67, and the outer end of the limit spring 67 is fixedly installed with a limit block 68.

[0032] In one embodiment of the utility model: limiting grooves 63 are provided on both sides of the installation groove 61, one end of the connecting frame 64 is adapted to the limiting groove 63, the size of the limiting block 68 is adapted to the limiting groove 63, and a threaded member 62 for connecting to the vehicle is fixedly installed in the middle position of the left side surface at the upper and lower ends of the installation groove 61.

[0033] Example 1, please refer to the attached Figure 1 -Attached Figure 5 The adaption groove 52 is used for seamless installation of the heat conducting sheet 51 and the heat dissipation frame 54 with the valve body assembly 1. The size of the adaption groove 52 is adapted to the upper shape of the valve body assembly 1, so that the heat conducting sheet 51 can perfectly fit with the valve body assembly 1 after being pasted on the surface of the valve body assembly 1.

[0034] Example 2, please refer to the attached Figure 1 -Attached Figure 5 , threaded holes 65 are penetrated through the upper surface of the connecting frame 64 near the two sides, and the threaded holes 65 are used to connect with the bolts on the valve body assembly 1. The threaded holes 65 of the connecting frame 64 are aligned with the bolt holes on the valve body assembly 1, and then the bolts of the valve body assembly 1 are aligned with the threaded holes 65 and tightened to fix the connecting frame 64 to the valve body assembly 1.

[0035] Specifically, after the heat conductive sheet 51 is pasted on the upper surface of the valve body assembly 1, the heat conductive sheet 51 quickly dissipates the heat inside the valve body assembly 1 to the external environment. Subsequently, the liquid after passing through the refrigerator 57 enters the circulation pump 55, and enters the refrigeration coil 58 from the water outlet of the circulation pump 55. Under the action of the circulation pump 55, the cooled liquid continues to move in the refrigeration coil 58, causing the heat dissipated by the heat conductive sheet 51 to be quickly cooled. When the temperature of the valve body assembly drops, the external environment temperature is also lowered, thereby improving the high temperature resistance of the entire valve body.

[0036] Specifically, when installing the acceleration valve body, first fix the threaded hole 65 on the connecting frame 64 to the valve body assembly 1, and install the installation groove 61 on the vehicle through the threaded member 62. When installing the entire acceleration valve body, you only need to press the limit block 68 to compress the limit spring 67 until the limit block 68 is completely retracted into the telescopic groove 66, and insert the connecting frame 64 into the installation groove 61 until the limit block 68 pops out of the limit groove 63 to complete the connection.

[0037] Working principle:

[0038] First, when installing the valve body assembly 1, first install the installation groove 61 on the vehicle through the threaded member 62, and install the connecting frame 64 on the bolt of the valve body assembly 1 through the threaded hole 65, then press the connecting frame 64 to compress the limit spring 67, until the limit block 68 is completely retracted into the telescopic groove 66, and then insert the connecting frame 64 into the installation groove 61 until the limit block 68 pops out from the limit groove 63, so that the connection between the valve body assembly 1 and the vehicle is completed, and at the same time, it is convenient for later disassembly and maintenance, and then add the refrigerant into the refrigerator 57. After the refrigerated liquid enters from the water inlet of the circulating pump 55, it enters the refrigeration coil 58 from the water outlet of the circulating pump 55, and then enters the refrigerator 57 to start the next cycle. Through the circulation, the external airflow is disturbed, the heat brought out by the heat conducting plate 51 is cooled, and the heat on both sides of the valve body assembly 1 is taken away, so as to improve the high temperature resistance of the valve body assembly 1. At this point, the whole work process ends.
