Direct way electromagnetic control valve of the present invention, comprise the main valve body that is provided with water intake and water outlet, it is characterized in that: on the water intake of described main valve body, be provided with valve seat, described main valve body inner chamber is coaxially arranged with main valve lumen control room, described control room is provided with towards water intake one side can be along the piston type flap of control room inwall axial slip, the exterior edge face of described flap coordinates and realizes the unlatching of valve or close with valve seat, described flap middle part is provided with for being communicated with the axial hole in water intake and control room, between described flap inner side surface and control room inner side surface, be provided with stage clip, the pilot line of described control room outside being located in main valve body be back to main valve body and control room between water outlet die cavity in, through drain opening, flow out again, on described pilot line, be provided with for regulating the electromagnetic priority valve of control room internal pressure.
In above-mentioned axial hole, be also equipped with the axis of guide, the external part of the described axis of guide is fixedly connected with valve base inner wall through radial guiding flow, offers axis conduit on the described axis of guide.
Above-mentioned flap middle part is provided with the spigot nut with axial hole.
Above-mentioned control room inwall is provided with the guide sleeve being slidably matched with flap.
Above-mentioned control room is provided with plug on the through hole of water outlet one sidewall.
Advantage of the present invention: this direct way electromagnetic control valve is a kind of hydraulic operated valve that solenoid valve is pilot valve of take.Utilize the opening and closing of electromagnetic priority valve control valve, save the energy.Can replace other valve Large Electric device.Install additional after additional device, can control the speed of opening and closing.Be widely used in water supply pipe net system and the town water supply engineerings such as tall building, living area.Control reaction accurately fast, according to electrical signal remote control opening and closing pipe roadnet, realize remote operation.And can replace gate valve and butterfly valve for Large Electric operation system.Close and steadily and not produce pressure surge.This valve volume is little, lightweight, easy to maintenance, esy to use, safe and reliable.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment, direct way electromagnetic control valve provided by the invention is illustrated.
Direct way electromagnetic control valve of the present invention, comprise the straight-through main valve body 1 that is provided with water intake and water outlet, it is characterized in that: on the water intake of described main valve body 1, be provided with valve seat 2, described main valve body 1 inner chamber is coaxially arranged with main valve lumen control room 3, described control room 3 towards water intake one side be provided with can be along control room the piston type flap 4 of 3 inwall axial slips, the exterior edge face of described flap 4 coordinates and realizes the unlatching of valve or close with valve seat 2, described flap 4 middle parts are provided with for being communicated with the axial hole 5 in water intake and control room 3, between described flap 4 inner side surfaces and control room 3 inner side surfaces, be provided with stage clip 6, the pilot line 7 of described control room 3 outside being located in main valve body 1 be back to main valve body 1 and control room 3 between water outlet die cavity 8 in, through drain opening, flow out again, on described pilot line 7, be provided with for regulating the electromagnetic priority valve 9 of control room 3 internal pressures.
In above-mentioned axial hole 5, be also equipped with the axis of guide 11, the external part of the described axis of guide 11 is fixedly connected with valve seat 2 inwalls through radial guiding flow 12, offers the axis conduit 13 in order to flow direction axial hole 5 on the described axis of guide 11.
Above-mentioned flap 4 middle parts are provided with the spigot nut 14 with axial hole.
Above-mentioned control room 3 inwalls are provided with the guide sleeve 15 being slidably matched with flap 4.
Above-mentioned control room 3 is provided with plug 16 on the through hole of water outlet one sidewall.
Working principle of the present invention: when valve feeds water from water intake, current flow through the axial hole in spigot nut on flap 4 and enter main valve lumen control room 3, and when electromagnetic priority valve is opened, the water in lumen control room 3 causes water outlet through electromagnetic priority valve stream.The aperture of electromagnetic priority valve is greater than the area of section of axial hole in spigot nut, the drainage rate that is main valve lumen control room 3 is greater than water intake velocity, therefore control room 3 chamber pressures reduce, and water intake pressure is opened main valve flap 4 and supplied water downstream, and main valve is in full-gear.When electromagnetic priority valve is closed, the water in main valve lumen control room 3 can not flow out, and main valve lumen control room 3 chamber pressures rise, and drive stage clip and flap 4 throttle downs.
The present invention does not limit to above-mentioned preferred forms, and anyone can draw other various forms of direct way electromagnetic control valves under enlightenment of the present invention.All equalizations of doing according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
