Abstract
The utility model relates to a rotary distribution valve, belonging to the technical proposal of relating to the rotary distribution valve, and comprising a valve cover. The utility model is characterized in that the interior of the valve cover is provided with a movable disc and a stationary disc which are matched; the valve cover and the stationary disc are provided with connection openings; disc bodies of the movable disc and the stationary disc are respectively provided with hole channels which are correspondingly matched in the mode of group according to equant angular positions; the contact surfaces of the movable disc and the stationary disc forms dynamic hermetic sealing; the movable disc is connected with a step drive mechanism. The rotary distribution valve uses one distribution valve to replace a plurality of electromagnetic valves or mechanical valves; fault points is decreased to be one, the operation is convenient, and the running is stable.
Description
The utility model belongs to valve, relates to a kind of technological scheme of rotary distributing valve.
Present mechanical valve or the solenoid valve that uses, can only control a pipeline mostly, in some main equipment or system equipment, often use a lot of control valves, cost height not only, and the fault point increases, and as the domestic medical oxygen producing device of having introduced countries such as the U.S., Britain, a solenoid valve came quick switching controls adsorptive process surplus device adopted 20, although the electromagnetic valve quality of import is higher, but always the fault point in the device does not catch up with in case keep in repair, and air feed will interrupt.
The purpose of this utility model is to overcome the deficiency of above-mentioned existing control valve technology, by the improvement of control valve structure, provides a kind of rotary distributing valve technological scheme of suitable multichannel control.
The purpose of this utility model is achieved through the following technical solutions, a kind of rotary distributor, comprise valve bonnet, it is characterized in that having in the valve bonnet Moving plate and the quiet dish of a pair of cooperation, valve bonnet and quiet dish are provided with connection mouth, offer the corresponding duct that cooperates in groups respectively by the five equilibrium angular orientation on the disk body of Moving plate and quiet dish, the dynamic hermetic seal of the surface of contact of Moving plate and quiet dish, Moving plate is connected with a step drive mechanism.The duct that the disk body correspondence of Moving plate and quiet dish cooperates in groups forms state logical or that close, and realization is to the logical of above-mentioned pipeline group or close control.
This kind rotary distributor, stepping drive the machine structure to be made up of cylinder, connecting rod, positive N tooth papillae wheel and transmission shaft, and the connecting rod that is connected with cylinder matches with positive N tooth papillae wheel, and positive N tooth papillae wheel is connected N 〉=3 with Moving plate by transmission shaft is coaxial.Moving plate has the corresponding state that cooperates in groups of N kind with the duct of quiet dish.
This kind rotary distributor replaces a plurality of solenoid valves or mechanical valve with a distributing valve, and the fault point reduces to one, and is easy to operate, stable.
Further specify the utility model below in conjunction with Figure of description, and provide embodiment.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model Moving plate.
Fig. 3 is the plan view of the utility model Moving plate.
Fig. 4 is the structural representation of the quiet dish of the utility model.
Fig. 5 is the plan view of the quiet dish of the utility model.
As shown in the figure, a kind of rotary distributor, comprise valve bonnet 5, it is characterized in that having in the valve bonnet 5 Moving plate 6 and the quiet dish 7 of a pair of cooperation, valve bonnet 5 and quiet dish 7 are provided with connection mouth 8, offer the corresponding duct that cooperates in groups respectively by the five equilibrium angular orientation on the disk body of Moving plate 6 and quiet dish 7, the dynamic hermetic seal of surface of contact of Moving plate 6 and quiet dish 7, Moving plate 6 is connected with a step drive mechanism.Step drive mechanism is made up of cylinder 1, connecting rod 3, positive N tooth papillae wheel 2 and transmission shaft 4, and the connecting rod 3 that is connected with cylinder 1 is taken turns 2 with positive N tooth papillae and matched, just the N tooth papillae take turns 2 with Moving plate 6 by 4 coaxial connections of transmission shaft, N 〉=3, present embodiment N=8.Offer the corresponding duct that cooperates in groups respectively by 45 degree position of halving on the disk body of Moving plate 6 and quiet dish 7.Positive N tooth papillae wheel 2 also can be driven by machinery, electromagnetism or the hydraulic drive mechanism of other routines.
The octadentate ratchet 2 of a to-and-fro motion rotary driving distributing valve of cylinder 1, connecting rod 3 rotates a 45, coaxial transmission shaft 4 drives Moving plate 6 and rotates a 45, the mated condition of a kind of Moving plate 6 of conversion and quiet dish 7, Moving plate 6 has eight kinds of corresponding states that cooperate in groups with the duct of quiet dish 7.Connection mouth on the valve bonnet 5 connects air I inlet ductwork, quiet dish 7 connects the inlet/outlet pipeline of zeolite molecular sieve adsorption tower A, B, C, D and oxygen II export pipeline, nitrogen III export pipeline respectively, and four zeolite molecular sieve adsorption towers in the may command medical oxygen producing device sequentially finish absorption 1, absorption 2 respectively, all press, along putting, put nitrogen, flushing, pressurising 1,2 eight sections omnibus control system processes of pressurising.
