Abstract
The invention relates to a distributed three-function valve. The valve comprises a valve body, a valve core, a valve position controller, adapter pipes, bearings, springs, a first one-way valve, sealing seats, sealing rings and a power head, and has three functions of working, blowing and closing the valve respectively. The valve is simple in structure and machining process and convenient to mount, six valves can be replaced by one valve, automatic control can be realized, the field pipeline is simplified, and the fault points are reduced; and therefore, the cost is greatly reduced.
Description
Technical field
The present invention relates to a kind of multifunction valve, or rather, relate to a kind of distribution type triple duty valve.
Background technique
Comprise oil circuit, main gas circuit and purge gas circuit, pressure gauge, oil gun and various valve for the oil system of ignition of the boiler in existing thermal power plant.This system needs eight valves, and wherein, oil circuit and gas circuit all need to install a stop valve 100, and oil circuit and gas circuit need be installed three stop valves altogether like this.System is also installed the valve that three need are controlled: main air valve 101, fuel tap 102, purging air valve 103, in addition, for preventing that fuel oil from entering gas circuit and polluting, system also is provided with two the second one-way valves 104.This system needs the number of valve many, and on-the-spot pipeline complexity, and complexity is installed, and fault point is many, and cost is high.So we are badly in need of developing a kind of multifunction valve, with a valve, replace a plurality of valves.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of distribution type triple duty valve.
The technological scheme that the present invention solves the problems of the technologies described above is as follows: a kind of distribution type triple duty valve, and this valve comprises: valve body, spool, valve positioner, adapter, bearing, spring, sealing seat, seal ring, unit head, the first one-way valve; Described unit head is fixedly connected with spool, and valve positioner is positioned at the end of valve body near unit head, has coordinated the control of valve position with unit head; Spool is nested in valve body, one side of described valve body is provided with oil inlet hole and inlet hole, opposite side is provided with oil outlet and air outlet hole, the axis place of described spool is provided with a passage, described oil inlet hole, inlet hole, oil outlet, air outlet hole all are connected with this passage, and the center of this passage is provided with described the first one-way valve; The seal ring of some is set between spool and valve body, spool is become to a plurality of chambeies with the separated between valve body.
Wherein, the seal ring that some is set between spool and valve body be in order to prevent oil in the valve core rotation process, gas is ganged up by gap and oil, gas leak outside; Spool two ends bearings, be, in order to prevent that lateral pressure that some valve position certainly leads to is poor, spool is pressed in to valve body surface, and impact is rotated and sealing.
The invention has the beneficial effects as follows: this valve arrangement and processing technology are simple, install more conveniently, and a valve can substitute a plurality of valves, and can realize automatically controlling, and simplify on-the-spot pipeline, reduce the fault point, and cost is reduced greatly.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described spool two ends bearings.
Further, adapter all is equipped with in the outside of described oil inlet hole, inlet hole, oil outlet, air outlet hole, and spring and sealing seat all are equipped with in inside.
Further, described spool is a cylindrical body.
Further, the number of described seal ring is three or four.
Further, between described oil inlet hole and inlet hole, the distance along valve body surface is greater than between oil outlet and air outlet hole the distance along valve body surface.
Further, the outlet diameter size of sealing seat is greater than the big or small 2-3mm in hole.
The beneficial effect that adopts above-mentioned further scheme is biased the moving in hole of offsetting the sealing pair that the spool corner error causes.
Further, described sealing seat is made with teflon or contraposition polyphenyl.
Further, described sealing seat and spool form the sealing pair intercoupled.

Embodiment
Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
Be illustrated in figure 1 longitudinal sectional drawing of the present invention, this valve comprises: valve body 1, spool 2, valve positioner 3, take over 4, rolling bearing 5, spring 6, the first one-way valve 7, sealing seat 8, seal ring 9, unit head 10, described unit head 10 is fixedly connected with spool 2, valve positioner 3 is positioned at the end of valve body near unit head 10, coordinated the control of valve position with unit head 10, spool 2 is nested in valve body 1, the spool two ends are supported with bearing 5, there is a main aperture coordinated with spool 2 at valve body 1 center, one side of valve body 1 is provided with oil inlet hole and inlet hole, opposite side is provided with oil outlet and air outlet hole, four side opening outsides of described valve body are equipped with and are taken over 4, spring 6 and sealing seat 8 are housed in hole, described spool is a cylindrical body, spool axis place is provided with a passage, described four side openings all are connected with this passage, the center of this passage is provided with first one-way valve 7, two above seal rings 9 are set between spool and valve body, spool and valve body matching gap are separated into to two and plural chamber.
Wherein, described oil inlet hole and inlet hole are greater than oil outlet and the air outlet hole distance along valve body surface along the distance of valve body surface.The outlet diameter of sealing seat is greater than size and is greater than hole 2-3mm.Described sealing seat is made with teflon or contraposition polyphenyl.And described sealing seat and spool form the sealing pair intercoupled.
It is as follows that the work of described distribution type triple duty valve is done mode:
After valve is received order, spool rotates under unit head drives, and 90 ° of every rotations are exactly a station, and rotating 360 degrees just has four stations, is respectively " work ", " work post-purge ", " closing ", " purging before work ".
The state of " work " of indicating in Fig. 3, the corresponding passage of the oil inlet hole of valve body, inlet hole, oil outlet, air outlet hole and spool is all linked up, and now the first one-way valve is pushed down sealing surface under the effect of oil pressure, spring, cuts off oil, gas circuit.Fuel oil and air by this valve enters oil gun like this, sprays oil gun after impingement mix, forms tiny mist of oil.
After " work " program, spool drives half-twist by unit head, enter work post-purge state, spool is closed the oil inlet hole of valve body, air outlet hole, inlet hole and oil outlet stay open state, and gas enters valve core channel by inlet hole, by gas pressure, push one-way valve open, enter oil gun through oil outlet, the trapped fuel in oil gun is blown into to burner hearth.
After the purge time that reaches setting, spool turns 90 ° again, and spool is by all inlet/outlet Close Alls of valve body, and valve is in " closing " state.
If valve is received again work order, spool turns 90 ° again, enters into " purging before work " program, to remove the cinder that may exist in oil gun, after setting purge time arrival, automatic rotation is 90 ° again, spool forwards " work " position again to, according to this circulation.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
