Description
Technical field
The utility model relates to a kind of multi-way valve, particularly relate to a kind of compact structure, level of integration high, control accurate machined flow small flow multi-way valve.
Background technique
Multi-way valve is the combination brake switch and proporting combined by multiple single valve body, for carrying out the control of oil circuit break-make to multiple control object.The oil circuit that the depth development of industry causes every profession and trade needs to control gets more and more, and change also increasing, existing multi-way valve product is difficult to realize new application demand.
Such as, present industrial control required precision is more and more higher, but traditional commutation valve body, each hatch frame of its internal control guiding valve is an annular opening, there is no other supplementary structure, so its precision controlling flow is not high enough, fretting performance is not enough, there will be larger departure in the application.
Model utility content
The purpose of this utility model be just to provide to solve the problem a kind of compact structure, level of integration high, control accurate machined flow small flow multi-way valve.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of machined flow small flow multi-way valve, comprise by a bolt assembled in series oil-feed valve body together, two commutation valve bodies and an oil return valve body, two described commutation valve bodies are installed between described oil-feed valve body and described oil return valve body, one end of described oil-feed valve body is provided with safety valve, the pressure oil port of the pressure oil port of described oil-feed valve body commutation valve body described with two is successively connected, the return opening of two described commutation valve bodies connects successively, and the return opening near the described commutation valve body of described oil return valve body is connected with the return opening of described oil return valve body; The peripheral wall of three opening both sides of the spool control valve of described commutation valve body is equipped with throttling groove, and described throttling groove communicates with corresponding described opening; And eight flow path grooves with the main oil gallery of this valve body communicating corresponding with three of described spool control valve openings are provided with in the valve body of described commutation valve body, wherein, two middle described flow path grooves communicate with the opening in the middle of described spool control valve, and each three described flow path grooves on both sides communicate with the opening on described spool control valve both sides respectively.
Preferably, the peripheral wall of three opening both sides of the spool control valve of described commutation valve body is evenly provided with four manual throttle grooves respectively.
The beneficial effects of the utility model are:
The utility model provides the machined flow small flow multi-way valve of an a kind of integrated oil-feed valve body, two commutation valve bodies and an oil return valve body, by arranging throttling groove on the spool control valve of commutation valve body, and the multiple flow path grooves corresponding with the opening of spool control valve are set in this valve body, thus achieve the accurate control of each commutation valve body and each holding function, both the accurate control of equipment operating had been beneficial to, turn improve the utilization ratio of main engine power, achieve energy-conservation object; This multi-way valve can independent utility, is suitable as again the fundamental composition unit of various complicated multi-way valve, when multiple multi-way valve combination, retains one of them oil return valve body.
Accompanying drawing explanation
Fig. 1 is the structural representation of machined flow small flow multi-way valve described in the utility model, and two commutation valve bodies in figure and oil return valve body are sectional structure;
Fig. 2 is that structural representation cuts open in the office of the spool control valve of commutation valve body described in the utility model, and in figure, ratio is greater than Fig. 1.
