Problems solved by technology

[0002] In long-distance pressurized water pipelines, the pressure of the pipeline is often too high due to the reduction of water consumption by users. In severe cases, the amount of water loss from the pipeline may increase greatly, and even the pipeline may rupture.
Most of the existing flow regulating valves are manual, and their structural forms mainly include gate valves, globe valves and cone valves. The above existing flow regulating valves have the following main disadvantages in actual use: large flow resistance, Severe cavitation, no hydraulic or electric control function, and cannot meet the requirements of frequent constant flow regulation

Embodiment 1

[0027] Such as figure 1 As shown, the present invention includes a valve body 1 with an inlet 17 and an outlet 18 at the bottom, a hydraulic cylinder 5 installed at the upper opening of the valve body 1, a valve cover that is reversed on the hydraulic cylinder 5 and installed integrally with the valve body 1 6. Insert through the bonnet hole in the middle of the bonnet 6 from top to bottom and pass through the hydraulic cylinder 5 and then insert it to the piston rod 11 at the bottom of the valve cavity, the electric drive mechanism and manual drive mechanism that drive the piston rod 11 to move up and down, and through the hydraulic pressure The liquid pressure change in the cylinder 5 automatically adjusts the additional valve that controls the piston rod 11 to move up and down, that is, the pressure control additional valve 7 .

[0028] A diaphragm assembly is installed between the hydraulic cylinder 5 and the valve cover 6, which divides the inner chamber of the hydraulic ...

Embodiment 2

[0036] Such as figure 2 As shown, in this embodiment, the difference from Embodiment 1 is that in this embodiment, a flow pressure gauge 19 for detecting the liquid pressure at the outlet 18 in real time is not provided and the electric control device is automatically controlled to achieve Control the microcomputer controller 20 that the piston rod 11 moves up or down. Therefore, in this embodiment, the present invention is a non-intelligent electric control hand, electric, hydraulic three-purpose Y-type multi-nozzle constant pressure flow regulating valve.

[0037] In the case of non-intelligent electric control, the present invention can be used as an electric lifting switch. After the electromagnetic switcher 10 and the piston rod 11 are in a connected state, the sliding sleeve 3 of the spray barrel can be driven by the hand and the electric integrated machine 9 to realize the control of the multi-nozzle valve. The lift in the seat 2 is to move up and down, so that the am...

Abstract

The invention discloses a manual, electrical and hydraulic three-function Y-shaped constant-pressure flow regulating valve with multiple spray holes, which comprises a valve body, a hydraulic cylinder, a valve cover, a piston pod, an electrical and manual driving mechanism and a pressure-control attachment valve, wherein the hydraulic cylinder is arranged on the upper part of the valve body; the valve cover is reversely covered on the hydraulic cylinder; the electrical and manual driving mechanism drives the piston rod to move upwards and downwards; a membrane sheet assembly which divides theinner cavity of the hydraulic cylinder into an upper cavity and a lower cavity and can move along with the piston rod upwards and downwards is arranged between the hydraulic cylinder and the valve cover; a valve seat with multiple spray holes is arranged in inner holes positioned in the valve body; a spray barrel slide sleeve is sleeved at the bottom of the piston rod and matched with the valve seat with multiple spray holes; and the pressure-control attachment valve is arranged on an outlet guide tube which is respectively communicated with a valve outlet, the upper cavity and the lower cavity. The invention is suitable for water supply systems, has the function that the pressure of the valve outlet is constant when the flow quantity of the system varies, and has the characteristic that the flow regulating valve can be electrically controlled, or realize constant-pressure flow regulation through hydraulic and automatic control under the condition of power losing or without power, andalso realize constant-pressure flow regulation through manual control when a special requirement is needed.

Description

technical field [0001] The invention relates to a flow regulating valve, in particular to a Y-type multi-nozzle constant-pressure flow regulating valve for hand, electricity and hydraulic. Background technique [0002] In long-distance pressurized water pipelines, the pressure of the pipeline is often too high due to the reduction of water consumption by users. In severe cases, the amount of water loss from the pipeline may increase greatly, and even the pipeline may rupture. Most of the existing flow regulating valves are manual, and their structural forms mainly include gate valves, globe valves and cone valves. The above existing flow regulating valves have the following main disadvantages in actual use: large flow resistance, The cavitation is serious, there is no hydraulic or electric control function, and it cannot meet the requirements of frequent constant flow regulation.
