The invention provides a one-way throttle valve and a manufacturing method thereof. The one-way throttle valve includes a valve body and a valve core. The manufacturing method includes: processing the valve body to have first diameters distributed in sequence and communicating with each other. hole, the second diameter hole and the third diameter hole, wherein the diameters of the second diameter hole, the first diameter hole and the third diameter hole decrease in turn; the valve core is processed into a bowl-shaped structure, wherein the valve core of the bowl-shaped structure The diameter of the outer edge is smaller than the diameter of the first diameter hole; the valve core is placed in the second diameter hole; the valve core is processed into a planar plate structure so that the valve core is restricted in the second diameter hole, wherein the planar plate The diameter of the outer edge of the spool of the shape structure is smaller than the diameter of the second diameter hole and larger than the diameters of the first diameter hole and the third diameter hole. The above-mentioned manufacturing method of the present invention is not only simple, but also reduces the number of parts of the one-way throttle valve and reduces the manufacturing cost of the one-way throttle valve.
Description
technical field [0001] The invention belongs to the technical field of fluid equipment, and specifically provides a one-way throttle valve and a manufacturing method thereof. Background technique [0002] A one-way throttle valve generally includes two ports, a first port and a second port. As the name implies, when the liquid enters the one-way throttle valve from the first port and flows out of the one-way throttle valve from the second outlet, the one-way throttle valve can throttle the liquid; when the liquid enters the one-way throttle valve from the second port One-way throttle valve, when the one-way throttle valve flows out from the first outlet, the one-way throttle valve will not throttle the liquid. Because of this characteristic, one-way throttle valves are widely used in many industries. [0003] However, the existing one-way throttle valve not only has a complex structure, but also has complicated processing techniques, resulting in high production costs. Fo...
