Abstract
The utility model relates to a pressure regulating reflux valve, and belongs to the class of valves. The utility model is provided for ensuring the safety pressure of a water supply pipeline. A triple valve body is utilized, and a one-way valve of a water inlet hole composed of a valve rod, a spring, a valve block and a flange sleeve is arranged in a hole relative to a water inlet of the valve body. When pressure in the water supply pipe is high, the one-way valve is pushed away, water flows in the water inlet pipeline of a water pump via the water inlet and the water outlet of the reflux valve, and the water can circulate in a short path. The reflux valve has the characteristics of simple structure and adjustable pressure.
Description
The utility model belongs to valve type
Carrying by the pump housing in the pipeline of liquid, particularly in the water supply pipe; Often occur the superpressure phenomenon in the pipeline, destroy pipeline in order to prevent high pressure; In pipeline, all need adopt the decompression safety measure.The safety measure that adopts is at present: utilize microcomputer control to drive the rotating speed of motor of water pump; When in pipeline, superpressure occurring, the motor revolution is reduced, reduce until stopping in pipeline, to send water; This control gear, cost is higher, is difficult to popularize.
The purpose of this utility model is: provide a kind of simple in structure, cost is low, the pressure regulating type reflux valve that is easy to popularize.
Technical measures of the present utility model are: adopt a three way valve, an one-way valve that is overlapped the water inlet of forming by valve rod, spring, valve piece, flange is housed in relative hole, the water inlet of valve body.
Reflux valve of the present utility model, because the outlet conduit of water inlet and water pump links, the water intake pipeline of osculum and water pump links, when pressure is higher in the water supply line, one-way valve in the reflux valve is open, and water circulates water in the water inlet of reflux valve, water intake pipeline that osculum flow back into water pump in short circuit, can not produce the superpressure phenomenon in the water supply line, safety water supply is had positive effect.
Accompanying drawing is a structural representation of the present utility model.
1 is three way valve among the figure, and an one-way valve by valve rod 5, spring 4, valve piece 2, the flange cover 3 water inlet A that form is housed in the relative hole of water inlet A.According to the needs of pressure, the pressure in the regulating valve stem 5 may command water supply lines, the water outlet pipeline with water inlet A and water pump during use links, and the water intake pipeline of osculum B and water pump links; When water pipe pressure was higher, valve piece 2 was open, and water flow back in the water intake pipeline of water pump through water inlet A, osculum B, and water can be guaranteed the safety pressure of water supply line through the reflux valve short-circuit cycle.
Claims (1)
1, a kind of pressure regulating type reflux valve is characterized in that:
A, a three way valve is arranged;
B, in relative hole, the water inlet of valve body, the one-way valve of a water inlet of being made up of valve rod, spring, valve piece, flange cover is housed.
