Problems solved by technology
[0003] The matching angle between the existing spool and the front bonnet is the same. Under the action of only the pressure oil on the back, the contact area is large, the sealing effect of the cone surface is not good, and it is easy to form interference and cause leakage, and the pressure oil on the back cannot be maintained. Pressure, the combination of the bonnet and the valve body adopts the way of interference press fit, but the length of the joint surface is only 2mm, the contact area is too small, and it is easy to fall off

The invention discloses a novel one-way valve assembly, which comprises a valve body, a valve cap, a valve element and a spring, wherein a spring is arranged in the valve body, the valve element is arranged in the spring, the valve cap is arranged at the bottom of the valve element, a tight fit angle of the valve element is 3-4 degrees larger than the angle of the valve cap, the valve cap and the valve body are combined in an interference press fit mode, so that the interference fit length is increased to 3 mm. And the valve body is processed into a sawtooth shape. According to the novel one-way valve assembly, the tight fit angle of the valve element is larger than the angle of the valve cap by 3-4 degrees, so that annular linear sealing is formed, the sealing effect is good, back pressure is easy to maintain, the interference fit length is increased to 3 mm, the sawtooth-shaped surface is machined on the valve body, and the friction strength between the valve body and the valve cap is increased, and therefore, the valve cap is effectively prevented from falling off.
Description
technical field [0001] The invention relates to the technical field of one-way valves, in particular to a novel one-way valve assembly. 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. The straight-through check valve is installed on the pipeline with a threaded connection. There are three types of right-angle check valves: threaded connection, plate connection and flange connection. [0003] The matching angle between the existing spool and the front bonnet is the same. Under the action of only the pressure oil on the back, the contact area is large, the sealing effect of the cone surf...
