Abstract
The utility model relates to a fluid control switching valve which is composed of a control fluid outlet, a piston cylinder, a piston, a connecting rod, a valve hole, a valve clack, a valve body, a liquid inlet and a liquid outlet. The utility model is characterized in that a spring is arranged below the valve clack. Via test, the valve has high sensitivity and reliability and convenient installation and operation when used for controlling the return water of a heating system of a normal pressure water boiler, and compared with an electromagnetic valve, the fluid control switching valve has low cost.
Description
The utility model relates to a kind of hydraulic control switch valve with liquid stream recloser.
What Dalian Zhuanghe's valve two factories produced is used for the piping flow size and uncontrolled automatic control float hydrovalve is arranged, be by valve body, flap, piston, piston cylinder constitutes, piston is controlled by the float position on the controlled canister liquid level in piston cylinder: when float rises or descend, liquid in the piston cylinder is pressed into or discharges, piston moves up and down, pass through connecting rod, drive the folding of flap, thereby the effect of playing the control flow rate size or having or not, its shortcoming is that the power that provided of float lifting on liquid level is little and slow, and the situation of cutting off liquid stream for needs immediately is inapplicable.
The purpose of this utility model is a kind of hydraulic control switch valve that can cut off pipeline liquid stream immediately of design.
Embodiment's accompanying drawings of hydraulic control switch valve of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, 1 is the import and export of control liquid, and 2 is valve body, and 3 is piston, and 4 is connecting rod, and 5 is the valve import, and 6 is flap, and 7 is spring, and 8 is valve outlet port, and 9 is valve opening, and 10 is piston cylinder.
The control of certain pressure enters piston cylinder 10 with fluid (gas or liquid, confession or external) from control liquid import 1.9 promote pistons moves down, and through connecting rod 4, promotes flap 6 and moves down, and a spring 7 is arranged below flap 6, and valve opening 9 is opened, and spring 7 is compressed, the liquid on the pipeline from enter the mouth 5 through valve port 9 to outlet 8.When the pressure of control liquid during less than the elastic force of spring 7, move on the flap 6, sealing valve opening 9 blocks liquid.
Successful examples of the present utility model is the heating system that is used for normal pressure heating hot water stove.The principle of automatic control of this system is as follows: when circulating hot-water pump starts, pump discharge supercharging (being generally 3-5Kg/cm), enter piston cylinder 10 from hot water of main line shunting, make described valve opening (this valve is contained in normal-pressure boiler backwater ingress), hot water is extracted out from boiler, be pressurized to high-order heating system through pump, hot water cooling back drops to this hydraulic control switch valve from a high position, enters normal-pressure hot-water boiler then.When unexpected power failure, the hydraulic pressure of pump disappears, and spring 7 blocks liquid stream the flap 6 tops closed valve opening 9 that comes up, and the hot water of high-order heating system can emptying yet, and the hot water in the normal-pressure boiler can not overflow yet.
On probation showing, the utility model control is sensitive reliable, compares cheaply, easy to install with solenoid valve, need not establish the device that produces control liquid stream in addition.
