Abstract
The utility model relates to a public controlling hole type conversion valve, which is the important improvement for the common conversion valve. The main technical feature of the utility model is that the public controlling hole type conversion valve adopts a set of public controlling holes to conduct the targeting combined control for a plurality of multi-position pieces. The public controlling hole type conversion valve has the advantages of simple structure, small size, convenient manufacture, convenient detection, reliable control performance, etc. The public controlling hole type conversion valve can be widely used for the mechanical equipment, the metallurgy equipment, the chemical industry equipment, etc., and the public controlling hole type conversion valve can conduct the targeting combined control for a plurality of multi-position pieces.
Description
The public control cellular type of the utility model rotary valve is to be used for the element that oil cylinder, cylinder, guiding valve etc. to some multidigit parts proceed to bit combination control.
Before the utility model is made, when the common rotary valve that uses is controlled the multidigit part both at home and abroad at present, requirement possesses on this rotary valve spool corresponding one group of control hole is arranged, need the multidigit number of packages amount of composite control many more, the group number of control hole is just many more on the spool, cause that this rotary valve complex structure, size are big, manufacturing and detection difficult, control performance is reliable inadequately.The utility model is conceived for the above-mentioned shortcoming that overcomes common rotary valve.
The utility model is the significant improvement to common rotary valve.On the spool of rotary valve, be provided with one group of public control hole, some multidigit parts are proceeded to bit combination control.Its structure such as Fig. 1, illustration is four dibit elements of control, that can realize that 16 kinds of differences put composite control in place axially joins oily rotary valve.
Structure of the present utility model is made up of handle (1), spool (2), valve body (4) pipe joint (6), positioning device (5), preceding valve gap (3) back valve gap parts such as (7).The pipe joint (seeing Fig. 1, Fig. 2) of the multidigit that on valve body, distributing part pilot line.Pressure oil injects spool by total oil inlet hole (8), one group of public control hole (9a, 9b) is arranged on spool (2), these control holes can be that boring (9a) communicates with pressure oil (gas) in the spool, also can be that groove (9b) links to each other with oil extraction (gas), flow back to oil (gas) pond by oil return (gas) pipe joint, make each pipe joint obtain different conditions combination logical, oil extraction (gas).
Working condition of the present utility model is: handle (1) is turned on the conversion gear that needs, by positioning hole (10) spool (2) is determined at set position by positioning device (5).Because the spool control hole makes the logical oil of each pipe joint (gas) state difference, just makes each multidigit part realize the composite control that puts in place that requires.
The public control cellular type of description of drawings: Fig. 1 rotary valve structural drawing.1---handle 2---spool 3---preceding valve gap 4---valve body 5---positioning device 6---the total oil inlet hole of pipe joint 7---back valve gap 8---.Fig. 2 spool unfolded drawing 9a---hole 9b---groove 10---positioning hole 11---oil-discharge trough Fig. 3 pipe joint distribution map 5---positioning device 6---pipe joint 12---oil returning pipe joint.
Characteristics of the present utility model are only can realize some multidigit parts are proceeded to bit combination control with one group of public control hole. The characteristics such as it has simple in structure, and size is little, manufacturing and easy to detect, and control performance is reliable. Can be widely used on the equipment such as machinery, metallurgy, chemical industry all need to all can employing the occasion that some multidigit parts proceed to bit combination control.
Claims (2)
1, the utility model is public control cellular type rotary valve, and it is made up of handle (1), spool (2), preceding valve gap (3), valve body (4) positioning device (5), pipe joint (6), back valve gap parts such as (7).It is characterized in that the public control hole that has one group can proceed to bit combination control on the spool of said rotary valve to the multidigit part.
2, according to the said rotary valve of claim 1, it is characterized in that the public control hole on the spool can be that hole (9a) communicates with spool pressure oil (gas), also can be that groove (9b) links to each other with oil extraction (gas) groove.
