Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a conveying valve. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. Valves are control components in fluid conveying systems and have functions such as shutoff, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief.

[0003] For example, a Chinese utility model patent (CN217714150U) discloses a new type of conveying valve equipment, which records: "including a valve tube, a flange, a control module, a switch, and a handwheel. The front and rear inner walls of both ends of the valve tube are fixedly installed with electric slide rails, and each of the electric slide rails is slidably provided with an electric slider." It also points out that "the existing conveying valves may cause blockages in the pipeline during specific use due to the possibility of conveying some highly viscous substances, especially at the connection of the conveying valve. Because of the valve switch, the flow rate of the section nearby is reduced, especially when the valve is not fully opened, which may easily cause blockage of the conveying valve on both sides of the section." Technical deficiencies.

[0004] In summary, it can be seen that the following technical problems exist in the prior art: the existing delivery valve is prone to blockage when delivering fluids with high viscosity, especially at the connection of the delivery valve. Since a valve switch is provided, the flow velocity near it is reduced, which can easily cause blockage on both sides of the valve switch. For this reason, the present application proposes a delivery valve. Utility Model Content
