Abstract
The utility model relates to a novel electric multi-way rotary valve, which is composed of a valve body, a valve cover, a valve flap, a transmission shaft and a motor. The valve flap which is provided with through holes is driven to rotate by the motor through the transmission shaft to cause the high voltage cavity on the valve cover to be communicated with a plurality of low voltage cavities in controllable way to realize remote controlling distribution. The utility model has good sealing performance and small volume, and the electric multi-way rotary valve is flexible to be rotated. The electric multi-way rotary valve can be used on the sprinkler, the leakage rate, the weight and the manufacturing cost of the whole sprinkler are reduced; the electric multi-way rotary valve is also suitable for the remote distribution of other liquid and other gases.
Description
The present invention relates to a kind of motor actucting multi-way rotary valve.
Each pipeline of sprayer truck pipe network system is respectively by the manual one by one controlled water flow break-make of control valve at present, needs with multi-functional conversion such as spray before satisfying, back spray, high spray, fire-fighting, self-primings, for enabling to finish multi-functional conversion separately at operator cabin, each pipeline must dispose corresponding solenoid valve and air valve and fixture thereof.Such pipe network system link is many, and leakage rate is big, the manufacture cost height, and installation and maintenance inconvenience, institute takes up space big, and brings difficulty for the tank body design model, and the utmost point need improve.And existing many logical rotary valves all can not satisfy the needs that its telecontrol multichannel is distributed.
The novel motor actucting multi-way rotary valve that the purpose of this invention is to provide a kind of energy telecontrol.
The present invention's motor actucting multi-way rotary valve comprises valve body, valve gap, flap, transmission shaft, angular displacement stroke switch, overload protection clutches and motor.Have three low-pressure cavity on the valve body at least, a hyperbaric chamber is arranged on the valve gap, have at least one port on the flap, flap separates low-pressure cavity and hyperbaric chamber between valve body and valve gap, and hyperbaric chamber is communicated with each low-pressure cavity is controlled, each low-pressure cavity inlet of valve body is equipped with Sealing.Work as starting electrical machinery; motor power drives with the joining flap of transmission shaft by overload protection clutches and transmission shaft and turns to the flap port when connecting a certain appointment low-pressure cavity; signal is sent in the angular displacement stroke switch action; by external connection electrical apparatus control system or the stall of computer order motor; the function conversion finishes; hyperbaric chamber communicates with this low-pressure cavity, and hyperbaric chamber pressure is just to the low-pressure cavity transmission.For making the flap rotational resistance little, flap adopts the axial limiting sliding pair to connect with transmission shaft, i.e. flap and transmission shaft rotational fixation, flap can transmission shafts to certain limit in mobile.Before the function conversion, hyperbaric chamber is driven press, flap and Sealing get loose, carry out the function conversion after, pressurize to hyperbaric chamber, flap is close to sealing to Sealing.For making valve volume little, the minimum range between every adjacent two low-pressure cavity of valve body can be less than flap port size.
Advantage of the present invention has been for having realized remote centralized control effectively, transposition conversion sensitivity, and favorable sealing property, volume is little, low cost of manufacture, installation and maintenance are convenient, and low-power machine also can meet the demands, energy saving.Particularly be applied on the sprayer truck, replaced existing sprayer truck solenoid valve and air valve group effectively, significantly reduced the pipe network system link, leakage rate is little, is convenient to the tank body shape design, has alleviated the weight and the cost of sprayer truck greatly.The present invention is equally applicable to other liquid and control is joined in the many reduction of fractions to a common denominators of gas.
Detailed technology content of the present invention is further specified by the embodiments of the invention and the accompanying drawing thereof that are used on the sprayer truck.
Fig. 1 is that embodiment is along valve A-A sectional view.
Fig. 2 is valve B among Fig. 1-B sectional view.

1Place's water outlet will be converted to water chamber A
3Place's water outlet, make water pump stop feedwater, water-inlet cavity (B) is driven and is pressed, flap (4) is the seal ring that gets loose because the elastic force effect of gravity and each seal ring (2) is glided, start micro motor (12), micro motor power drives flap through clutch (8,9), transmission shaft (7), pin (6) and coupling shaft (5) and rotates, and flap through hole (C) goes to water chamber A
3During the place, the knock over cam micro limit switch sends signal, by external connection electrical apparatus control system or the stall of computer order micro motor, and water-inlet cavity this moment (B) and water chamber (A
3) be communicated with, allow water pump feed water, water-inlet cavity (B) pressurizes, and moves on the flap (4) with each seal ring (2) to compress, and press water just passes through flap through hole (C) from water chamber A by water-inlet cavity (B)
3Flow out.(C) goes to water chamber A when the flap through hole
2During the place, cam also clashes into sensitive switch, but this action can not make external connection electrical apparatus control system or computer send halt instruction.
Lower semi-clutch has spanner mate or decorative pattern on (8), so that manually transposition operation is about to carry with it on first clutch (9) and separates, rotates lower semi-clutch (8).Just can carry out manual transposition conversion.Have Leak hole (D) on the valve body, prevent waterborne oozing.Whenever the minimum range (a) between adjacent two is less than flap through-hole diameter (d) for five water chambers of valve body, and water chamber whether directly controlled by water pump by water outlet, in order to reducing valve volume.The junction button (13) that five water chamber outlet ports of valve body link to each other with pipe joint is compressed with valve body by hold-down ring (14) and fixes, and unclamps hold-down ring, and junction button is just free to rotate, so that install.
