Problems solved by technology
In the existing general pneumatic joints, if the sealing performance is poor and the fluid leaks, the fluid pressure and flow rate in the system will decrease, which will affect the fluid transmission effect or control ability; the leaked liquid will corrode nearby components or cause a short circuit in the circuit system
However, the existing hydraulic and pneumatic joints are simple in design and difficult to control the flow rate, and the ordinary structural design cannot fully meet the user's requirements

The invention relates to a connecting device capable of quickly disassembling and assembling, in particular to a quick couplingmale plug. The quick couplingmale plug comprises a plug body, a valve element and a valve seat, the plug body is internally provided with the valve element and the valve seat, the valve seat is fixedly arranged on the inner wall of the middle of the plug body, the slidablevalve element is smoothly arranged on the valve seat, the inner wall of the front part of the plug body is hollow, an oblique plane is formed on the inner wall, the front part of the valve element isin contact with the inner wall, the head part of the valve element is exposed, the head part of the valve element is in a cone shape, a retaininggroove is formed in the outer wall of the plug body, the rear part of the valve element is in a cylinder shape, the inner wall of a cylinder communicates, and a circulation hole is formed in the side wall of the front part. The quick couplingmale plug has the beneficial effects that a flow kit is used for controlling the size of a flow channel, the flow kit is in a cross shape or other shapes with solid cores in the middles, the sizes of the solid cores determine the magnitude of the flow rate, the airtightness is good, friction between parts is less, it can be ensured that leakage is avoided under the maximum pressure, and sealing structure designensures the high and low temperature sealing performance and the service life.
Description
technical field [0001] The invention relates to a quick disassembly connecting device, especially a quick connector male plug. Background technique [0002] Quick connector is a kind of quick connection or disconnection pipeline, which realizes quick disassembly and assembly connection device, and is widely used in petroleum, metallurgy, hydropower, engineering machinery, ships, electromechanical equipment and other fields. In the existing general pneumatic joints, if the sealing performance is poor and the fluid leaks, the fluid pressure and flow rate in the system will decrease, which will affect the fluid transmission effect or control ability; the leaked liquid will corrode nearby components or cause a short circuit in the circuit system. However, the existing hydraulic and pneumatic joints are simple in design and difficult to control the flow rate, and the common structural design cannot fully meet the user's requirements. Contents of the invention [0003] In order...
