In water treatment system or chemical industry equipment, because pipeline is wrong vertical complicated, finishing some process often needs many valve controls.In order to reduce the valve quantity on the pipeline, the form of valve is led to multi-way valve such as threeway, four-way from simple one, however, the industrial process (realizing the positive and negative journey that flows through as a set of equipment pipeline) that special requirement is arranged still is difficult to realize valve control with existing multi-way valve, particularly mechanical valve control.A kind of as disclosing in CN 912161108 patents " the spherical stop valve of four-way ", Fig. 1 is the structural representation of this valve.It is made up of valve body 1, valve gap 2, valve pad 3 and spool 4.Valve body 1 is a cylindrical shell that is provided with some radial passages, valve gap 2 is loaded on valve body one end, and there is axial hole at the center, spool 4 is by one section rotatingshaft and can constituting around the spherical surface body that axis freely rotates, have in the spherical surface body one with valve gap on axial hole communicate the duct that communicates successively with each radial passage all the time.This four-way valve can solve the connection successively on multitube road, saved the quantity of valve in the pipeline, advanced one logically, that is: only had two pipelines to connect but only can finish one during this orientation of spool angle revolution, other orientation is for closing, so valve itself can not be finished counter-current process simultaneously.As in water-treating equipment, the filtration purge tank of middle water treatment not only needs sewage water filtration totally, often also wants oppositely back washing filter layer, and above-mentioned four-way valve then can not be finished the positive and negative journey that flows through.

CN861088859 proposes a kind of three position five-way valve, and it is to finish the three-position five-way process by hydraulic pressure, pneumatic combination, and device is complicated, and is subjected to the restriction of hydraulic pressure, aerodynamic conditions.

The purpose of this utility model provides a kind of mechanical five-way valve, can change five passages by the orientation of adjusting spool, has at least two gears can realize that one advances threeway, thereby accomplishes that a valve changes the flow direction, finishes the positive and negative journey that flows through.

The purpose of this utility model is to realize by following technological scheme.

Valve body of the present utility model is one and has the radially housing of valve opening on five different azimuth, be lined with liner in the valve opening, be connected with five pipelines simultaneously by flange valve gap or valve seat at each valve opening place, the solid of rotation spool that can freely rotate around self axis is housed in the valve body, spool turning axle one end has the spindle nose of rotation to join with handle with sleeve, have six radially tap holes on its revolution side face, gusset by the valve core inside setting separates, make per two radially tap hole communicate, form three shunting chambeies, the other end along valve core axis has an axial hole, be communicated with a certain shunting chamber, make spool form a distributing T-pipe chamber, the axial hole of spool fixedly communicates with the valve opening in an orientation of valve body all the time, and the position of tap hole radially on the spool side face, be according to the orientation of valve opening on the valve body corresponding layout, its scheme is: according to valve core rotation orientation difference, with guarantee to have simultaneously three or one radially tap hole respectively with valve body on three valve openings or 1 valve opening connect.That is: when a certain radially tap hole on the spool distributing T-pipe chamber communicates with a certain orientation valve opening on the valve body, or have another shunting chamber two radially on tap hole and the valve body other two valve openings connect simultaneously, spool forms one at this moment and advances the threeway state; Or the two radially tap holes of shunting on the chambeies all are in blocked state in addition, form one and advance a logical state.Because the distributing T-pipe chamber can be connected with other two shunting chambeies respectively by turns, then can finish positive and negative twice one and advance the threeway process.

Above-mentioned spool revolution side face can adopt regular turning surface such as sphere, cylinder.

Effect of the present utility model:

Owing to have valve opening on the valve body five positions,, save valve quantity so can make a valve connect the multitube road.

The threeway that spool is provided with and the shunt structure of two two reduction of fractions to a common denominator stream chambeies and six tap holes make spool that three different gears can be arranged at least, finish three kinds of processes.Advance the gear of threeway particularly positive and negative twice one, can finish the positive and negative journey that flows through.
