Abstract

The invention is a shutoff valve with pilot electric control ball valve, comprising main valve body, inlet, outlet, valve core, bottom hole of valve core, where the valve core is jacketed with guiding sleeve and seal ring, upper and lower baffles are arranged in the main valve body, the upper part of the main valve body is equipped with cover plate, the main valve body, the baffles, the valve core and the cover plate form upper room, outer room and inner room, the central part of the valve core and cover plate is equipped with spring, and flow guide pipe is equipped with electric control ball valve. And it can be widely applied to oil fields, chemical industries, drinks, medicines, tap water, natural gas and other industries for flow control, having advantages of operating flexibility and convenience and saving labor, high accuracy, simple installation, long service life, and being suitable for remote control, single control or group control, etc.

Description

The stop valve of band guiding electric controlling ball valve

Technical field

The present invention relates to a kind of stop valve, particularly have the stop valve of the pilot valve of electronic control ball valve.

Background technique

The open and close of stop valve are often adopted the mechanical type handwheel to rotate device such as electronic or pneumatic and are realized.Mechanical handwheel rotates the open and close to stop valve, and slow in one's movements, labor intensity is big; Electric drive and electromagnetism adhesive, the former power consumption is big, and latter's porcelain piece is frangible, and working life is short; Pneumatic motor and the air pump of needing, the sealing requirements height, cost of production is bigger.

Through market survey and retrieval, do not find as yet to adopt electric-controlled ball valve to control the material object and the related data of the open and close of stop valve as pilot valve.

From the consideration that is close of relevant technologies such as simple installation and low cost, the present invention rotates the control stop valve with the mechanical type handwheel and opens and closes the contrast material of making prior art.

Summary of the invention

At the above-mentioned deficiency of prior art, the objective of the invention is to design that a kind of cost is lower, sensitivity good, laborsaving, the stop valve that can carry out the band guiding electric controlling ball valve of telecontrol.

The invention has the beneficial effects as follows: operate nimble, logical close quick, laborsaving, precision is high, installations is simple, long service life, be suitable for remote control, single control or colony and control.

Purpose of the present invention can realize by following measure:

It contains main valve body, import, outlet, go up through-flow chamber, following through-flow chamber, spool, upper clapboard and lower clapboard, upper part of the main valve body has cover plate, dividing plate in main valve body wall and the main valve body, spool, be with the chamber between the cover plate, the mistress, inner room, spool is class alms bowl shape, the spool bottom outlet is arranged at the spool bottom, pressure ring is arranged at spool top, the spool periphery has guide sleeve, the last inwall of guide sleeve has seal ring, the central part of spool and cover plate is fixed with spring, and last chamber has honeycomb duct to be communicated with the mistress, and the aperture of spool bottom outlet is less than the internal diameter of honeycomb duct, electric-controlled ball valve is installed on the honeycomb duct, is connected with control wiring on the electric-controlled ball valve.

Base plate is arranged at the main valve body bottom, and base plate has pollutant exhaust hole, and this hole is equipped with sealing nut.

Description of drawings

Fig. 1 is a structural representation of the present invention

Fig. 2 is a scheme of installation of the present invention.

Embodiment

The present invention is further specified below in conjunction with embodiment and with reference to accompanying drawing: the present invention contrasts the stop valve of mechanical type handwheel rotation and has done as above to improve: cancelled handwheel, valve rod, interior lifting nut, change guide pad and guiding groove into guide sleeve 5, change the cheese spool into class alms bowl shape spool 14, and open spool bottom outlet 15 in the bottom, the former valve rod hole of loam cake transformed into be pod apertures, open another pod apertures again on mistress 4 outer wall, two pod apertures are connected by honeycomb duct 9.Because of spool 14 changes class alms bowl shape into, nature will be gone up through-flow chamber and be divided into upward chamber 11, mistress 4, inner room 13, electric-controlled ball valve 8 is installed on the honeycomb duct 9, central part at the

cover plate

7 and 14 ends of spool adds spring 10, spool 14 tops add the pressure ring 12 that compresses seal ring 6, and cover plate 7 and pressure ring 12 compress the outer periphery and the inner periphery of seal ring 6 respectively.

This valve is that example illustrates working state with the controlled water flow: set electric-controlled ball valve 8 earlier and open, as the no user water, the then existence of valve internal cause spool bottom outlet 15, following through-flow chamber 17 between import 2 and the outlet 16, last chamber 11, mistress 4, inner room 13, be full of water in the honeycomb duct 9, the hydraulic balance of upper and lower part in the valve body is under the elastic force effect of the deadweight of spool 14 and spring 10, spool 14 falls valve closing; In case user's water, outlet 16, mistress 4, the water of going up in the chamber 11 outflow, and top hydraulic pressure reduces, and the hydraulic pressure in the following through-flow chamber 17 backs down spool 14 greater than top hydraulic pressure, opens valve, normal water supply.As close electric-controlled ball valve 8, and then the water in through-flow chamber 17 injects inner room 13 and last chambers 11 through spool bottom outlet 15 down, and to pressure during with balance, under spool 14 gravity and spring force effect, spool is closed once more, not water flowing of main valve.

Managerial department as tap water, by electric-controlled ball valve 8 being carried out wired button mode, electromagnetic emission and receive mode control, be more preferably the stroke sensor that fluid pressure sensor or spool 14 are installed on main valve body 1, the coupled computer program controlled mode is carried out remote control, single control or colony's control.Corresponding sensor, chip is commercially available or programming voluntarily.This valve is as using in the environment of different specific weights such as oil, rock gas, different pressures, specification and elastic force that then should corresponding adjustment spring 10, or size and the wall thickness of adjusting spool, pressure ring increase and decrease weight.

The electric-controlled ball valve 8 that the present invention adopts is commercially available, and the import 2 of this electric-controlled ball valve 8, outlet 16 are tapped on the honeycomb duct 9.
