Clockwork self-deceleration valve protection device

Abstract

The invention provides a spring type self-decelerating valve protecting device. The device comprises a spring module, a blade module, a sliding rail plate and a pipeline module; the spring module comprises a casing, a spring and a rotating shaft; the blade module comprises a connecting rod and an impeller; strip-shaped grooves are formed in the sliding rail plate; a round cake-shaped pipeline is designed on the pipeline module and includes an upper layer and a lower layer; and pipeline openings are designed in the upper layer and the lower layer of the round cake-shaped pipeline respectively.By the aid of the device, the flow speed of a fluid inside the pipeline can be reduced, so that the stress required during opening and closing of a valve is reduced; and meanwhile, the acting force isabsorbed by the aid of the elastic structure of the spring device, so that the buffer protection effect is realized for the device.

Description

technical field [0001] The invention relates to the field of valves, in particular to an automatic protection valve device. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters of the conveying medium; according to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc.; Flow, anti-backflow, voltage stabilization, diversion or overflow pressure relief and other functions; the existing valves can realize the switch of fluid, including manual switch and automatic switch, and the valve with special requirements also has a timing function, which can realize timing switch, In order to realize the control of fluid flow; the existing valve device needs to apply force to the valve stem in the process of opening and closing to control the opening and closing of the internal structure of the valve; for the valve body with butterfly valve structu...
