Problems solved by technology
[0003] The existing one-way valve can only allow the oil to flow in one direction, so that it can be kept open when the oil flows in a fixed direction, and it can be kept closed when the oil flows in the reverse direction. However, in some cases, the oil needs to be reversed. One-way flow, that is, the oil flows in one direction from the original water outlet to the original water inlet. At this time, the one-way valve needs to be installed in reverse, or two one-way valves are used, which is time-consuming and laborious to disassemble, and the oil is easy to flow out. polluted environment

The invention discloses a one-way valve with an adjustable stop direction. The one-way valve comprises a first shell and a second shell which are connected with each other, and further comprises a first valve element which is in sliding matched connection to the first through hole and a first spring which extrudes the first valve element as well as a second valve element which is in sliding matched connection to the first through hole, a first spring which extrudes the first valve element, a first pull rod connected with the first valve element, and a second pull rod connected with the secondvalve element, wherein a first through hole is formed in the first shell; a fourth connecting hole which communicates with the first through hole is formed in the second shell; and the first valve element can seal the fourth connecting hole. The one-way valve is characterized in that a second through hole is formed in the shell, wherein a second connecting hole which communicates with the second through hole is formed in the first shell; the second connecting hole mutually communicates with the fourth connecting hole; the second valve element can seal the second connecting hole; the first pullrod can be pulled out outwards and fixed; and the second pull rod can be outwards pulled and fixed. The one-way valve can conveniently control a reverse flow direction of oil liquid.
Description
technical field [0001] The invention relates to a one-way valve, in particular to a one-way valve with an adjustable cut-off direction. Background technique [0002] The one-way valve is that the fluid can only flow along the water inlet, but the outlet medium cannot flow back, commonly known as a one-way valve. One-way valve is also called check valve or check valve. Used in hydraulic systems to prevent reverse flow of oil flow, or used in pneumatic systems to prevent reverse flow of compressed air. There are two types of check valves, straight-through and right-angle. [0003] The existing one-way valve can only allow the oil to flow in one direction, so that it can be kept open when the oil flows in a fixed direction, and it can be kept closed when the oil flows in the reverse direction. However, in some cases, the oil needs to be reversed. One-way flow, that is, the oil flows in one direction from the original water outlet to the original water inlet. At this time, th...
