Abstract
A kind of cock type three-way valve of using on the water factory filter tank of being suitable for, its characteristics are that it produces the transmission system that vertically moves and rotate and forms by being provided with less than the taper cock of valve body inner casing height and driving this plug in having three valve port cone valves, thus realized a valve replace two valves, compact structure, take up space little, cost is low, do not have the purpose of friction switching and low flow resistance.The present invention also can be applicable in the mobile system of junctions occasion fluid.
Description
The present invention relates to the valve that uses on the filter tank, a kind of waterworks, particularly about carrying out Fraquent start in three water routes and switching the valve that occasion is used.
At present, behind the filter tank, waterworks, be used for water delivery or diversion flushing filter tank and water system is defeated by in supporting threeway, mainly separate the threeway that valve member forms with two groups of valves that are used to cut off current etc. and be defeated by water control system by three-way pipe, native system is owing to adopt the multicomponent combination, therefore, the equipment input is many, floor space is big, engineering cost is high, waste energy, overhaul of the equipments and maintenance workload increase, and particularly is unfavorable for concentrating control automatically.
In order to solve above-mentioned deficiency, the present invention will provide a kind of combined type, long lifetime, nothing friction switching, low energy consumption, low cost, be convenient to concentrate the cock type three-way valve of control automatically.
Purpose of the present invention will reach by following measure: promptly valve totally is the bottom flange (1) that is provided with bearing (D) by the center portion, the center portion is provided with the bonnet (10) of axis hole (E), communicating along garden Zhou Fangxiang and with inner chamber has the cone type valve body (7) of three place's valve ports (A, B, C), and dress taper cock (4) and valve body are equipped with Mechanical ﹠ Electrical Transmission system (W) composition outward in the valve body.
For taper cock (4) and valve body (7) inner chamber are matched, and can realize underloading, nothing friction switching, it is except that tapered bucket formula structure, its working depth is less than the work clear height of valve body (7) inner chamber, outer surface lining sealing gasket (6), inner side surface by mechanical coupling method fixedly a slice be used to reduce the guide plate (5) of flowage friction resistance, its fan-shaped bucket pushes up respectively by last pin (8), downside pin (3) supporting axle (2) that the rotatingshaft (9) that passes axis hole (E) is housed and supported by bearing (D) up and down.
Mechanical ﹠ Electrical Transmission system of the present invention (W) is by the steering gear that turns to retarder (13), turns to actuating motor (19) to form that drive connection takes place by key (12) and rotatingshaft (9); By vertical transmission device of forming by mechanical coupling form fixing leading screw (15), nut (16), longitudinal deceleration device (17) and servo longitudinal motor (18) with rotatingshaft (9); By being enclosed within the moving cover (F) on the rotating collar connected in star (G) and being welded in the moving push rod (14) that overlaps on (F), the projection (20) that is turned to retarder (13) to drive also has cock to vertically move upper limit position limit switch XK
1Cock vertically moves lower bound range switch XK
2, cock turns to termination position limit switch XK under the A-C communicating state
3, cock turns to three valve ports (A, B, C) and all stops position limit switch XK under the cut-off states
4Turn to termination position limit switch XK under the A-B communicating state with cock
5The electrical signal device that constitutes is formed.Vertically transmission device also can be formed the vertical transmission device of hydraulic pressure by joint sleeve (21), piston rod (22), oil hydraulic cylinder (23) and solenoid directional control valve.Can also adopt the manually-operable of lever mode from reducing cost, reach the purpose of vertical transmission.
The drawing explanation of accompanying drawing:
Fig. 1 is the cock type three-way valve structural representation.
1 is bottom flange among the figure, and 2 is supporting axle, and 3 is downside pin, and 4 is tapered cock, 5 is guide plate, and 6 is sealing gasket, and 7 is valve body, 8 is last pin, and 9 is rotatingshaft, and 10 is bonnet, 12 is key, and 13 for turning to retarder, and 14 is push rod, 15 is leading screw, and 16 is nut, and 17 are the longitudinal deceleration device, 18 is the servo longitudinal motor, and 19 for turning to actuating motor, and 20 is projection.
Fig. 2 is a cock type three-way valve plan structure schematic representation.
A, B, C are valve port among the figure.
Fig. 3 is a cock type three-way valve Electrified Transmission principle schematic.
XK among the figure
1For cock vertically moves upper limit position limit switch, XK
2For cock vertically moves lower bound range switch, XK
3For cock turns to termination position limit switch under the A-C communicating state, XK
4For turning to three valve ports (A, B, C), cock all stops position limit switch, XK under the cut-off state
5For cock turns to termination position limit switch under the A-B communicating state.
Fig. 4 is the vertical hydraulic control system schematic representation of cock type three-way valve.
21 is joint sleeve, and 22 is piston rod, and 23 is oil hydraulic cylinder, and 24 is solenoid directional control valve.
The present invention is below in conjunction with 1 to 3 one of them embodiment's of description of drawings cock type three-way valve groundwork principle: when cock (4) by as scheme the electrical apparatus control system shown in (3) by rotatingshaft (9), leading screw (15), vertical drive connection of longitudinal deceleration device (17) and servo longitudinal motor (18), cock (4) is promoted to it outer surface bonding sealing gasket (6) break away from valve body (7) the inner casing conical surface and just stop to vertically move, like this cock (4) outer surface under bonding sealing gasket (6) and valve body (7) the inner casing conical surface frictionless condition, again by turning to retarder (13), turn to actuating motor (19), switch to valve port (B) or (C), or to three valve port (A, B, C) all end, after the to be switched termination, by servo longitudinal motor (18) and vertical driving mechanism thereof, the interior working position of valve casing is inserted in cock (4), thereby reached purpose of the present invention.
Another embodiment wherein: promptly can realize purpose of the present invention equally by as shown in Figure 4 hydraulic control system.
The present invention has following advantage compared to existing technology:
1, because valve body is provided with three valve ports, and be provided with therein taper cock moving up and down, thus the effect that a valve replaces two valves had, and have compact conformation, account for the little characteristics in tool space.
2, since the taper cock in this valve like as a bucket formula shell structure, and outer surface adhering and sealing pad, aspect ratio valve body inner casing height is little, so when switching rotation, have no friction, long service life, the reliable characteristics of sealing.
3, because the taper cock in this valve, its barrel formula inboard is provided with deflector, so have the characteristics of the little and water flow stationary of flow resistance.
