Abstract
The utility model relates to a guide piston stop valve, which is composed of a valve body, a piston, an outer sleeve of the piston, a valve cover, a micro control valve and a spring, wherein, the valve body is provided with the outer sleeve of the piston, and the piston is arranged in the outer sleeve of the piston. The piston is used for replacing a valve clack, and the piston can move up and down to open and close the valve. The stop valve having a large caliber can be controlled by minimal electric power.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of low-function valve.
Background technique
Traditional valve mainly is manually, and its structure comprises the flap of valve body and screw rod control, all these valves all are by slewing maneuver, open or close water-flowing path, finish the switch of valve, directly it is changed into electronicly, power consumption is too big, does not reach requirements of saving energy.
Summary of the invention
In order to overcome the existing too big deficiency of valve power consumption.The utility model provides a kind of pilot piston type stop valve, and it is self pressure that utilizes water in the pipeline, the elastic force of spring, and with minimum power consumption, the switch of control large bore valves, thus reach purpose of energy saving.
The technical solution adopted in the utility model is to realize like this.
A kind of pilot piston type stop valve, it is made up of valve body, piston, piston jacket, valve gap, micro-control valve, spring.Have in circular hole, the circular hole in the center upper portion of valve body piston jacket is installed, piston is installed in the piston jacket, the piston lower end is a frustoconic shape, central authorities have micropore, piston lower end and valve seat contact seal, upper end at valve body is equipped with valve gap, between valve gap and piston, spring is installed, central authorities are equipped with micro-control valve in the valve gap upper end, middle part and right side at valve gap have via, micropore on the piston communicates with the micro-control valve import, and micro-control valve outlet communicates with via on the valve gap.The valve body upper right has via, and the via on the valve gap communicates with via on the valve body.
The beneficial effects of the utility model are, the control of valve has realized controlling bigbore stop valve with small electronic rate, and actuator is operated in the bistable state state, and stable state does not consume energy, and simple in structure.
