Four-way low-damping double-acting check valve

Abstract

The invention provides a four-way low-damping double-acting one-way valve. The four-way low-damping double-acting one-way valve is an integrated structure, with an upper discharge one-way check valve with an upper discharge check valve and a The one-way check valve of the lower feed port, the material directly enters through the one-way valve of the lower feed port, and is discharged directly through the one-way valve of the upper discharge port.

Description

technical field [0001] The invention relates to the field of one-way valves, in particular to a four-way low-damping double-acting one-way valve applied to sludge pumps. Background technique [0002] Hydraulic piston sludge pump sewage pump is a tool that uses strong pressure to realize mud or sewage transmission. It is an indispensable equipment for engineering production and environmental protection equipment. Hydraulic piston sludge pump sewage pumps currently on the market use hydraulic cylinders as power The cylinder drives the piston movement of the working cylinder, and the inlet and outlet adopt a three-way joint. Two check valves are respectively installed as the inlet one-way check and the outlet one-way check. This structure will inevitably cause the material to pass through during the feeding and discharging process The tee, some elbows and the transmission pipeline are too long, resulting in increased resistance, which affects the operating efficiency and manufa...

[0002] Hydraulic piston sludge pump sewage pump is a tool that uses strong pressure to realize mud or sewage transmission. It is an indispensable equipment for engineering production and environmental protection equipment. Hydraulic piston sludge pump sewage pumps currently on the market use hydraulic cylinders as power The cylinder drives the piston of the working cylinder, and the inlet and outlet adopt a three-way joint. Two check valves are respectively installed as the inlet one-way check and the outlet one-way check. This structure will inevitably cause the material to pass through during the feeding and discharging process The tee, some elbows and the transmission pipeline are too long, resulting in increased resistance, which affects the operating efficiency and manufacturing cost of the whole machine, and the size of the whole machine is too large to waste resources and on-site installation space; the imported and exported one-way valve is Angle-through type, that is, the inlet and outlet of the check valve are at 90 degrees, and the material is prone to turbulence during the transmission process; there is no cooling system in the cylinder of the working cylinder, and the heat generated during the operation of the equipment cannot be conducted and dissipated in time, resulting in the aging of the piston seal of the working cylinder Failure; the hydraulic cylinder is used as a power cylinder, because the installation position of the reversing device is fixed when the hydraulic cylinder is reversing, the motion inertia and the hysteresis of the reversing valve are extremely easy to cause the piston and the two ends of the cover to collide and cause the cylinder to hit the cylinder
