Abstract
The invention provides a novel distributing valve. The novel distributing valve is mainly driven by a stepper motor and can ensure that each pipeline can be precisely communicated. A rotating valve and a fixing valve are pressed through screw rods and springs so as to avoid liquid leakage which is caused by abrasion of seal blocks. A middle seal block is arranged in the middle of the rotating valve, a seal block 3 which is arranged on the rotating valve and the middle seal block are hollow and communicated and communicate all liquid inlets and all liquid outlets in sequence when the rotating valve is rotated.
Description
Technical field
A kind of novel distributing valve of the present invention is practically applicable to various gases and liquid multi-pipeline UNICOM.
Technical background
Present various distributing valve generally takes motor to be fixed on the upper end of distributing valve, at first will pull down motor during maintenance and could keep in repair; Use optoelectronic switch that each pipeline is positioned, installment and debugging is all very difficult; Each pipeline opening has a seal ring because the medium walked of each pipeline may be different, the expansion of seal ring may be also sample not, the situation that the seal for pipe joints that the pipeline that will have at last can be sealed with is not tight.
Summary of the invention
In order to overcome the deficiency of existing various distributing valves, the present invention uses stepper motor to drive the distributing valve rotation, can guarantee to make accurately UNICOM of each pipeline; Only the pipeline opening in UNICOM has sealing material, thereby avoids because the medium difference causes that the expansion of sealing material is different with shrinkage rates and causes leakage; The connection of distributing valve uses screw rod to add the connection of spring, avoids because the leakage that the wearing and tearing of sealing material cause.
The technical solution adopted for the present invention to solve the technical problems is: some liquid entering holes in the circumferential direction of the circle distribute on standing valve, the centre of standing valve is that (liquid entering hole can be worked as liquid outlet to liquid outlet, liquid outlet also can be worked as liquid entering hole, and liquid entering hole and liquid outlet can exchange).Be evenly distributed with sealing block 1, sealing block 2, sealing block 3 with the corresponding circumference of the import of standing valve on rotating valve, sealing block 1, sealing block 2 mainly are the levels that auxiliary seal piece 3 guarantees rotating valve and standing valve.In the centre of rotating valve the intermediate seal piece is arranged, sealing block 3 is hollow with the intermediate seal piece on the rotating valve, and UNICOM, can be communicated with each liquid entering hole and liquid outlet successively when the rotation rotating valve.Rotating valve and standing valve rely on screw rod to add spring and compress, and avoid like this because the leakage that the sealing block wearing and tearing cause.There is the interfix piece (can use bearing to replace) of a hollow centre of rotating valve and standing valve, guarantee that rotating valve and standing valve are coaxial, the intermediate seal piece is fixed on the rotating valve by the center of interfix piece, and liquid also can flow out from the liquid outlet on the standing valve by the intermediate seal piece.One plane bearing is arranged, the resistance when reducing the rotating valve rotation below pressing plate.The rotating part of distributing valve is driven by stepper motor, at rotating valve one gearwheel is arranged, and at stepper motor one small gear is arranged.At rotating valve or gearwheel one zero-bit sign is arranged, the proof distributing valve resets when control panel detects the zero-bit sign by detecting switch, when certain liquid entering hole of needs UNICOM and liquid outlet, control panel is as long as direction and the step number that need to rotate to certain liquid entering hole position to stepper motor input reset position or position are just passable.
The invention has the beneficial effects as follows: 1, convenient by debuging examination; 2, operation accurately; 3, failure rate is low; 4, easy to maintenance.

Embodiment
Stepper motor (19) and standing valve (12) are fixed on fixed plate (18), and rotating valve (9) is on standing valve (18), and rotating valve (9) and standing valve (18) are coaxial by interfix piece (3) center of assurance.Upward be evenly distributed with sealing block 1 (2), sealing block 2 (10), sealing block 3 (11) with the corresponding circumference of liquid-inlet (13) of standing valve (18) at rotating valve (9).Standing valve (18), interfix piece (3), rotating valve (9) gearwheel (8) plane bearing (6) pressing plate (7) stack up in order, pass fixed plate (18) and pressing plate (7) is fixed up standing valve (18) and rotating valve (9) by spring (14), set screw nut (17) with standing screw (15).Identify (23) by controller (21) by the zero-bit that detecting switch (22) detects, the position of perhaps remembering, calculate the direction and the step number that need the unicom pipeline position, rotate by wire (20) control step motor (19), stepper motor (19) rotation makes small gear (1) rotation, small gear (1) rotarily drives gearwheel (8) rotation, gearwheel (8) rotarily drives rotating valve (9) rotation, rotating valve (9) rotation makes the liquid entering hole (13) and liquid outlet (16) UNICOM that needs unicom pipeline, and solution enters distributing valve by liquid-inlet (13) and flows out distributing valve by sealing block 3 (11) intermediate seal pieces (4) by liquid outlet (16).
