Description

Technical Field

[0001] The utility model relates to the technical field of one-way valves, in particular to a wear-resistant one-way valve for gold mining. Background Art

[0002] In the gold mining process, check valves are important fluid control components and are widely used in hydraulic systems and pipeline systems to prevent equipment damage or system failure when the fluid flows in the reverse direction. The main function of the check valve is to allow the fluid to flow freely in one direction while preventing the fluid from flowing in the opposite direction.

[0003] In the harsh environment of gold mining, the one-way valve needs to withstand multiple challenges such as high pressure, high flow, wear and corrosion. Therefore, the wear resistance and service life of the one-way valve have become the focus of industry attention. At present, in order to increase the wear resistance of the one-way valve, the key parts of the one-way valve are usually coated with a wear-resistant coating. However, most of the one-way valves currently used are difficult to disassemble, so the wear-resistant coating cannot be maintained, and the damaged coating cannot be repaired in time, which affects the life of the one-way valve. For this reason, we propose a wear-resistant one-way valve for gold mining. Utility Model Content

[0004] The utility model aims to provide a wear-resistant one-way valve for gold mining to solve the problems raised by the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wear-resistant one-way valve for gold mining, comprising a valve body, a liquid outlet pipe is connected to the outside of the valve body, a retaining sleeve is fixedly installed inside the valve body, the valve body is slidably installed inside the guide column, and a valve core matched with the retaining sleeve is installed at one end of the guide column;

[0006] A sealing cover is installed at one end of the valve body, a plurality of mounting seats are installed on the outer side of the valve body, the sealing cover and the mounting seats are fixed by bolts, and an elastic component is arranged between one side of the sealing cover and the guide column.

[0007] Preferably, the stop sleeve is fixed to the valve body by bolts.

[0008] Preferably, the valve core is in a truncated cone shape, and the outer side of the valve core abuts against one side of the stop sleeve.

[0009] Preferably, a sealing gasket is bonded to one side of the sealing cover, and the sealing gasket is located between the sealing cover and the valve body.

[0010] Preferably, the elastic component includes a connecting column fixedly mounted on one side of the cover, a connecting plate fixedly mounted on one end of the connecting column, a spring seat fixedly mounted on the outer side of the connecting plate, and a spring connected between the spring seat and the guide column.

[0011] Preferably, one end of the spring is fixed to one side of the spring seat, and the other end of the spring is fixed to one side of the guide column.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The wear-resistant one-way valve is used in gold mining. The internal surfaces of the one-way valve are coated with a wear-resistant coating, so as to ensure the wear resistance of the one-way valve when used in the hydraulic system and pipeline system in gold mining. When in use, the fluid enters the valve body from the right end of the valve body, pushing the valve core and the guide column to move in the direction close to the spring seat, so that the fluid passes through the retaining sleeve and leaves the liquid outlet pipe. When the fluid enters from the liquid outlet pipe, the valve core resists the retaining sleeve to close the valve body, ensuring the one-way conduction function of the one-way valve.

[0014] 2. This wear-resistant gold mine uses a one-way valve. When disassembling, first unscrew the bolts connecting the cover and the mounting seat to take out the cover. The cover is taken out together with the guide column and the valve core through the connecting column, connecting plate, spring seat, and spring. Then, unscrew the bolts connecting the stopper sleeve to the valve body to remove the stopper sleeve. At this time, it is convenient to check and repair the valve body, liquid outlet pipe, and the wear-resistant coating on the surface of the stopper sleeve, guide column, and valve core, thereby further extending the service life of the one-way valve and making its inspection and maintenance more convenient.
