Description

Technical Field

[0001] The utility model relates to the technical field of cable brackets, in particular to a high-strength hydraulic valve. Background Art

[0002] Hydraulic valves are needed in both engineering machinery and automotive fields. Hydraulic valves are an automated component operated by pressurized oil. Hydraulic valves are mainly controlled by the pressure oil of a pressure-matching valve and are usually used in combination with an electromagnetic pressure-matching valve. Hydraulic valves are generally divided into manual operation and electrical control, and hydraulic valves can be divided into flow valves, pressure valves and directional valves.

[0003] During the process of connecting the hydraulic pipes, some existing hydraulic valves have no gasket protection, so the hydraulic pipes have a certain air tightness when connected, which makes the connection strength of the hydraulic valves relatively low, and the connection between the hydraulic pipes and the hydraulic valves is prone to loosening. Therefore, those skilled in the art provide a high-strength hydraulic valve to solve the problems raised in the above background technology. Utility Model Content

[0004] In view of the defects in the prior art, the utility model provides a high-strength hydraulic valve, which can fix the hydraulic pipe during the connection process under the action of the arc block inside the gasket, thereby improving the connection strength, and can enhance the sealing of the two during the connection process under the action of the gasket.

[0005] Preferably, a high-strength hydraulic valve comprises a hydraulic valve mechanism, both side surfaces of the front side of the hydraulic valve mechanism are fixedly connected with a connecting mechanism, and both side surfaces of the hydraulic valve mechanism are fixedly connected with a clamping mechanism;

[0006] The connection mechanism includes two connection pipes, washers are fixedly connected to one side surface of the two connection pipes, inner grooves are formed around the inner walls of the two washers, springs are fixedly connected to the centers of the inner surfaces of the multiple inner grooves, connection blocks are fixedly connected to one side surface of the multiple springs, and arc blocks are fixedly connected to one side surface of the multiple connection blocks. When the hydraulic pipe is inserted into the hydraulic valve, the arc block is rebounded by the spring inside the washer, and then when the hydraulic pipe is completely connected to the hydraulic valve, the arc block can squeeze the hydraulic pipe under the action of the spring, thereby fixing the hydraulic pipe to a certain extent, so that the hydraulic pipe can be connected more tightly and more securely under the action of the washer.

[0007] Preferably, the hydraulic valve mechanism includes two hydraulic valve bodies, and a plurality of heating pipes are provided on the upper end surfaces of the two hydraulic valve bodies. In winter, the hydraulic valve is affected by the cold temperature, so that the liquid inside the hydraulic valve freezes, and it is difficult to unscrew the hydraulic valve when it is needed. Under the action of the heating pipe, hot water is added to the heating pipe, so that the liquid inside the hydraulic valve is thawed, so that the hydraulic valve can be unscrewed in cold weather.

[0008] Preferably, the hydraulic valve body includes a base layer, and an anti-corrosion layer is fixedly connected to the outer surface of the base layer. The anti-corrosion layer can enhance the corrosion resistance of the surface of the hydraulic valve, so that the hydraulic valve can still be used in a relatively harsh environment. The main material of the anti-corrosion layer is epoxy resin.

[0009] Preferably, a friction layer is fixedly connected to one side surface of the plurality of arc blocks, so that the friction force of the arc blocks on the surface of the hydraulic pipe can be enhanced under the action of the friction layer, so that the hydraulic pipe can be firmly connected under the action of the arc plate inside the gasket.

[0010] Preferably, the clamping mechanism includes a first fixing block and a second fixing block, and the center of one side surface of the first fixing block is fixedly connected to an electric telescopic rod through an elongated groove. The electric telescopic rod can extend or shorten the motor protection box.

[0011] Preferably, a motor protection box is fixedly connected to one side surface of the electric telescopic rod, a rotating motor is fixedly connected to one side surface of the motor protection box, a rotating shaft is fixedly connected to the output end of the rotating motor, and the upper and lower end surfaces of the rotating shaft are fixedly connected to the multi-stage electric telescopic rod. The rotating shaft is rotated under the action of the rotating motor, so that the two multi-stage telescopic rods on the rotating shaft are in a vertical state, and under the action of this state, the multi-stage electric telescopic rod is extended, so that the first fixed block and the second fixed block are fixedly connected together. When the multi-stage electric telescopic rod in the vertical state is shortened, the first fixed block and the second fixed block can be separated, so that the inside of the hydraulic valve can be inspected.

[0012] Preferably, a square groove is provided at the center of the second fixing block, and the main function of the square groove is to store the multi-stage electric telescopic rod when it is vertically unfolded.

[0013] The beneficial effects of the utility model are embodied in:

[0014] 1. When the hydraulic pipe is inserted into the connecting pipe on one side of the hydraulic valve body, the hydraulic pipe is squeezed by the arc block fixedly connected to the connecting block through the spring side of the inner groove under the action of the inner groove inside the gasket on one side of the connecting pipe. In this way, the connecting pipe and the hydraulic pipe can be further secured during the connection process, and the gasket can make the connection between the two more tightly during the connection process, which effectively improves the sealing performance and connection strength of the hydraulic valve to a certain extent.

[0015] 2. The electric telescopic rod inside the first fixed block is extended into the second fixed block, and then the rotating motor inside the electric telescopic rod is rotated under the action of the electric protection box on one side of the electric telescopic rod, so that the multi-stage electric telescopic rod at the output end of the rotating motor can be unfolded, and then the electric telescopic rod is shortened, so that the first fixed block and the second fixed block are connected more tightly, and the sealing of the hydraulic valve is further enhanced, and then the multi-stage electric telescopic rod and the electric telescopic rod are shortened to separate the two fixed blocks. In this way, the components inside the hydraulic valve can be inspected and repaired, and this method is convenient to separate the two, thereby improving the efficiency of the internal inspection of the hydraulic valve and shortening the inspection time.

[0024] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0026] The connecting mechanism 2 includes two connecting pipes 201, and a gasket 202 is fixedly connected to the surface of one side of the two connecting pipes 201. The sealing performance of the hydraulic valve body 101 when connecting the hydraulic pipe can be improved under the action of the gasket 202. Inner grooves 203 are opened around the inner walls of the two gaskets 202. Springs 204 are fixedly connected at the center of the inner surfaces of multiple inner grooves 203. Under the action of the springs 204, the arc block 206 can be extended and retracted. One side surface of multiple springs 204 is fixedly connected to connecting blocks 205, and one side surface of multiple connecting blocks 205 is fixedly connected to arc blocks 206. The function of the arc block 206 is to fix the connected hydraulic pipe, so that the hydraulic pipe connection is more secure.

[0027] The hydraulic valve mechanism 1 includes two hydraulic valve bodies 101, and a plurality of heating pipes 102 are provided on the upper end surfaces of the two hydraulic valve bodies 101. By pouring hot water into the heating pipes 102 in cold weather, the hydraulic valve bodies 101 can be thawed. The hydraulic valve bodies 101 include a base layer 10101, and an anti-corrosion layer 10102 is fixedly connected to the outer surface of the base layer 10101. The anti-corrosion layer 10102 can improve the overall corrosion resistance of the hydraulic valve bodies 101 under the action of the anti-corrosion layer 10102, so that the hydraulic valve bodies 101 can still be used in harsh environments. A friction layer 207 is fixedly connected to one side surface of a plurality of arc blocks 206, and the hydraulic pipes can be connected more securely under the action of the friction layer 207.

[0028] The clamping mechanism 3 includes a first fixed block 301 and a second fixed block 302. An electric telescopic rod 303 is fixedly connected to the center of one side surface of the first fixed block 301 through a long groove. The motor protection box 304 can be extended or shortened under the action of the electric telescopic rod 303. A motor protection box 304 is fixedly connected to the surface of one side of the electric telescopic rod 303. The motor protection box 304 can protect the rotating motor 305 under the action of the motor protection box 304. A rotating motor 305 is fixedly connected to the surface of one side inside the motor protection box 304. A rotating shaft 306 is fixedly connected to the output end of the rotating motor 305.

A square groove 308 is opened at the center of the second fixed block 302. The main function of the square groove 308 is to store the vertically unfolded multi-stage electric telescopic rod 307.

[0029] Working principle: When the hydraulic pipe is connected to the connecting pipe 201 before and after the hydraulic valve body 101, the spring 204 and the arc block 206 inside the washer 202 squeeze the hydraulic pipe under the action of the washer 202 on one side of the connecting pipe 201, so that the hydraulic pipe and the connecting pipe 201 are more firmly connected during the connection process, and the sealing of the connecting pipe 201 and the hydraulic pipe can be enhanced under the action of the washer 202 when the hydraulic pipe is connected. When it is necessary to inspect the parts inside the hydraulic valve body 101, first shorten the multi-stage electric telescopic rod 307, and then shorten the electric telescopic rod 303. In this way, the first fixed block 301 and the second fixed block 302 are separated, so that the hydraulic valve body 101 is divided into two. In this way, the inside of the hydraulic valve body 101 is inspected.
