Abstract

The utility model provides a multi-way valve. The multi-way valve comprises a valve body on which at least two inlet and outlet ports are arranged, an impeller which is provided with a motor and is arranged in the cavity of a valve body, and a valve core matched with the valve body. A channel which is communicated with the inner cavity of the valve body is arranged on the valve core. A motor drives the impeller to rotate to make the fluid in the inner cavity of the valve body generate swirling flows to push the valve core to make motion to cause the connection and the disconnection of the valve core channel and the valve body, so that the purpose of guiding or stopping the fluid is achieved.

Description

Multiple-way valve

The utility model relates to a kind of valve, particularly relates to a kind of multiple-way valve.

Present widely used solenoid valve be by electromagnetic force be used for control valve core motion, complex structure, noise is big, the cost height only can be controlled two fluid break-makes between container, can not overcome extraneous hydrodynamic pressure, changes the flow direction of fluid arbitrarily.

The purpose of this utility model is to provide a kind of eddy flow strength that produces by fluid to promote valve core movement, the multiple-way valve of control fluid break-make.

The utility model multiple-way valve is achieved in that it comprises the valve body that is provided with at least two import and export, places the impeller of body cavity translator, the spool that cooperates with valve body.Have the passage that communicates with body cavity on the spool.Wherein spool inwall or outer wall surface are generally roughened surface, and be promptly uneven, more helps fluid eddy flow strength and promote spool.Moreover the fit system between spool and valve body generally can be divided into two kinds, first rotation cooperation.During for this kind fit system, the spool bore with channel connection should be set on spool, and on the body cavity wall and/or on the non-fitting surface of spool limiting stopper be set, make spool forward or reverse on certain horizontal position in body cavity.It two is screw-thread fit, and promptly spool moves up and down by screw thread, and the spool bore with channel connection can be set on spool when cooperating for this kind, also spool bore can be set.

The working procedure of the utility model multiple-way valve is, this multiple-way valve can be connected with timer or electric/manual switch, and the control motor just changes, and the counter-rotating certain hour makes the valve core rotation several angle, or is in halted state.When motor rotates impeller when rotating, make the fluid in the valve body produce rotation, promote valve core movement by fluid eddy flow strength, cause passage on the spool to be communicated with or disconnect, thereby reach conducting or close the purpose of fluid with the valve body import and export.Simultaneously, the power that throws away of impeller rotation can change the flow direction of fluid arbitrarily.

The advantage of the utility model multiple-way valve is by the driven by motor wheel rotation, produces the fluid eddy flow, slowly drives valve core movement, and noise is little, and is reliable durable, simple and compact for structure, is used to realize the connection of a plurality of containers or pipeline enclosure fluid.

Describe the utility model embodiment in detail below in conjunction with accompanying drawing.

Embodiment 1:(Fig. 1)

The utility model multiple-way valve comprises being provided with imports and exports 1,2,3 and 4, and the valve body 5 of band limiting stopper 12, place the impeller 7 of valve body 5 inner chamber translators 6, be rotatably assorted with valve body 5 and with the spool 8 of limiting stopper 12, have the passage 9 that communicates with valve body 5 inner chambers on the spool 8, and the spool bore 10,11 that is communicated with passage 9.When motor 6 forward or reverse, impeller 7 makes the fluid of valve body 5 inner chambers produce eddy flow, promotes spool 8 and rotates, make its import and export 2 with spool bore 11 or/and import and export 4 and be communicated with spool bore 10, perhaps cut off, fluid can be by the import and export 2 on the valve body 5 or/and 4 inflows or outflow during connection; Fluid then can not be from importing and exporting 2 or/and 4 inflows or outflow during partition.When motor shuts down, then keep the certain position of spool 8, promptly keep spool bore 10,11 and valve body 5 to import and export 4,2 be communicated with or the partition state.

Embodiment 2:(Fig. 2)

The utility model multiple-way valve comprises being provided with imports and exports 1,2,3 and 4 valve body 5, places the impeller 7 of valve body 5 inner chamber translators 6, with the spool 8 of valve body 5 screw-thread fit.Have the passage 9 that communicates with valve body 5 inner chambers on the spool 8, and the spool bore 10 that is communicated with passage 9.When motor 6 forward or reverse, impeller 7 makes the fluid in valve body 5 inner chambers produce eddy flow, promoting spool 8 rotates, spool 8 is moved up or down by screw thread, thereby make the spool bore 10 on the spool 8 be communicated with or cut off, fluid is flowed into or outflow valve body 5 inner chambers from importing and exporting 2 or 3 with import and export 2 or 3.When motor 6 shuts down, then keep spool 8 certain positions, promptly keep spool bore 10 and import and export 2,3 be communicated with or the partition state.

Embodiment 3:(Fig. 3)

The utility model multiple-way valve comprises being provided with imports and exports 1,2 valve body 5, places the impeller 7 of valve body 5 inner chamber translators 6, with the spool 8 of valve body 5 screw-thread fit, has the passage 9 that communicates with valve body 5 inner chambers on the spool 8.When motor 6 forward or reverse, impeller 7 makes the fluid in valve body 5 inner chambers produce eddy flow, promoting spool 8 rotates, spool 8 is moved up or down by screw thread, thereby make and import and export 2 and be communicated with or cut off with valve body 5 inner chambers, fluid is flowed into or outflow valve body 5 inner chambers from importing and exporting 1, flow out or inflow from importing and exporting 2 again.When motor 6 shuts down, then keep spool 8 certain positions, promptly keep importing and exporting 1 on off operating mode.

Claims (4)

1, a kind of multiple-way valve comprises valve body, places the impeller of body cavity translator, and the spool that cooperates with valve body is characterized in that at least two import and export are arranged on the valve body, has the passage that communicates with body cavity on the spool.

2, multiple-way valve as claimed in claim 1 is characterized in that spool inwall or outer wall surface are uneven.
