The designations in the drawings have the following meanings: 1. the water valve comprises a main water pipe, 2, a pipeline, 3, a valve body assembly, 4, a spring, 5, a piston, 6, a movable rod, 7, an inspection valve, 8, a valve body, 9, a butterfly valve sheet, 10, a shaft, 11 and a rotary table.
Detailed Description
The invention is described in detail below with reference to the figures and the embodiments.
As shown in fig. 1 and 2, an automatic pressure regulating valve for a branch pipe is composed of a valve body 8 assembly 3 and a pressure assembly provided on a branch pipe 2.
Along the water flow direction, the valve body 8 assembly 3 is arranged at the front end of the pressure assembly; the valve body 8 assembly 3 consists of a valve body 8, a butterfly valve plate 9, a shaft 10 and a rotary table 11, wherein the rotary table 11 rotates the shaft 10, and the butterfly valve plate 9 is linked to open and close in the valve body 8; moreover, the outer ring of the turntable 11 is provided with a complete periphery of gears in a fluted disc shape; the outer circle of butterfly valve piece 9 is equipped with the leak protection ring, preferably rubber material to increase the closure of butterfly valve piece 9 outer circle and valve body 8.
The pressure assembly consists of an L-shaped pressure regulating pipe, a spring 4, a piston 5 and a movable rod 6; the spring 4 is arranged in the pressure regulating pipe cavity, one end of the spring is connected with a piston 5 with the same section as the pressure regulating pipe cavity, the other end of the spring is connected with a movable rod 6, and one side of the movable rod 6 is in a rack shape and is in toothed connection with a fluted disc.
An access valve 7 is arranged at the front end of the piston 5 and at the water inlet of the pressure regulating pipe; the movable rod 6 is provided with a matched guide groove which can be arranged in the outer frame of the whole device and can be independently arranged, namely a bracket fixed with the branch pipe is arranged, the guide groove is arranged at the top end of the bracket, and the support function is realized.
During the operation of the water supply system,
the spring 4 with proper elasticity, the movable rod 6 and the tooth density on the turntable 11 can be correspondingly selected according to the water supply pressure, and the tooth density corresponds to the opening degree of the butterfly valve plate 9.
When water supply pressure is too big, the big water of branch pipe 2 (pressure regulating pipe) oppresses piston 5 and makes spring 4 receive the compression, and then promotes movable rod 6 and removes to valve body 8, rotates through fluted disc linkage butterfly valve block 9 promptly and tends to the closure, reduces the flow of rivers, reaches the purpose of decompression to avoid rivers water pressure too big, reduce rivers and cross valve head loss.
When the pressure is too low, the water pressure in the branch pipe 2 (pressure regulating pipe) is low, and is not enough to apply pressure to the piston 5 or the applied pressure is low, and the spring 4 is in a pressure release state. The water flow from the main pipe pushes the butterfly valve plate 9 to enlarge the cavity, and simultaneously the movable rod 6 is linked through the shaft 10 to push the movable rod 6 to move towards the branch pipe; the water flow is increased, and the head loss of the overflow valve is reduced, so that the water pressure of the branch pipe is raised back to the normal water supply pressure.
I.e. during operation, to the water supply pressure required by the user by adjusting the force of the spring 4.
When the water supply needs to be cut off in the maintenance and other working conditions, the control valve of the water supply main water pipe 1 is cut off firstly, and then the maintenance valve 7 is closed to carry out maintenance or other operations on the system.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent variations fall within the scope of the present invention.
