Abstract

The invention relates to the technical field of valve equipment, and discloses a manual vacuum deflation safety valve. The manual vacuum deflation safety valve comprises a valve body; the valve consists of two parts of a check valve cavity and a ball valve cavity; one side of the check valve cavity is fixedly connected with a filter screen; one side of the filter screen is fixedly connected with awater inlet; the upper surface of the valve body is fixedly connected with a fixed block; the internal of the fixed block is movably connected with a connecting rod through a movable rod; the end, far from the fixed block, of the connecting rod is movably connected with a water baffle plate through the movable rod; the bottom of the fixed block is fixedly connected with a limiting plate; and a spring is fixedly connected between the water baffle plate and the limiting plate. The manual vacuum deflation safety valve is more reliable and convenient to deflate through a handle, a rotating rod and a rotating block; and the check valve cavity uses an elastic effect of the spring for guaranteeing one-way flowing of water currents to realize adjustment of a water way angle in a valve ball so asto guarantee the practicability of the manual vacuum deflation safety valve.

Description

technical field [0001] The invention relates to the technical field of valve equipment, in particular to a manual vacuum deflation safety valve. Background technique [0002] Valves are the control components in the fluid delivery system. They have the functions of cut-off, adjustment, diversion, prevention of reverse flow, pressure stabilization, flow diversion or overflow pressure relief. At present, valves are widely used in pipeline systems, mainly to prevent fluid backflow pollution. The problem of the water source, the valve stem is moved by the change of the pressure in the pipeline, so that the valve is opened in the forward direction or closed in the reverse direction, so that the fluid can flow through the valve in the forward direction and prevent the reverse flow, but the change of the water pressure causes the flow Unstable, unable to adjust the flow in the pipeline, which leads to the waste of water resources caused by excessive flow. At the same time, during u...
