Abstract
The invention discloses a pipe telescopic stroke valve, comprising a piston sleeve and a piston rod, wherein the piston rod is sleeved with the piston sleeve; the pipe telescopic stroke valve is characterized in that the cavity at the top end of the piston sleeve communicates with an upper pipe, the lower pipe opening of the piston rod communicates with a lower pipe, the upper pipe opening of the piston rod communicates with the cavity of the piston sleeve, the inner wall of the middle part of the piston sleeve is provided with a groove, the piston rod moves in the piston sleeve, and only when both the upper and lower pipe openings reach the groove, the upper pipe opening can communicate with the lower pipe opening. According to the pipe telescopic stroke valve, the pipes are arranged in a sleeving and telescopic manner to achieve connection and disconnection, so that the pipe telescopic stroke valve is simple in structure, safe and reliable.
Description
Technical field
The present invention relates to a kind of switch valve, especially relate to a kind of position limit switch valve of flexible pipeline.
Background technique
In fields such as hydraulic transmission, pneumatic equipment and special purpose machine tools, be useful stroke valve, stroke valve is, while moving to certain position or certain range of movement for movable part, make hydraulic tubing or air-pressure duct conducting or close.In existing equipment, the hydraulic tubing passing through between two movable parts or air-pressure duct are all to adopt flexible pipe to connect, and flexible pipe repeatedly stretches and is easy to aging with bending action.The stroke valve using in existing equipment is, in movable part travel range, contact is set, and when moving element touches contact, makes hydraulic tubing or air-pressure duct conducting or closes.Existing stroke valve is installed more complicated, takes up room large, and some equipment cannot be installed because of space problem.
Summary of the invention
In order to solve in prior art, between two movable parts, adopt flexible pipe to connect, flexible pipe stretches and existing stroke valve installation complicated take up room large problem easy aging with bending action repeatedly, the invention provides another pipeline extension stroke valve, this pipeline extension stroke valve adopts the sheathed and flexible mode of pipeline realize the conducting of pipeline and close, simple in structure, safe and reliable.
The technological scheme that technical solution problem of the present invention adopts is: a kind of pipeline extension stroke valve, comprise piston sleeve and piston rod, described piston rod is set in described piston sleeve, it is characterized in that: described piston sleeve top cavity volume is communicated with upper pipeline, lower nozzle in described piston rod is communicated with lower pipeline, upper orifice in described piston rod is communicated with the cavity volume of described piston sleeve, on described piston sleeve inwall, groove is set, when described piston rod moves in described piston sleeve, when described upper orifice and described lower nozzle arrive described groove, described upper orifice and described lower nozzle are communicated with by described groove.
Wherein, one end of described piston sleeve and described piston rod is mutually sheathed, the other end of described piston sleeve and described piston rod is separately fixed on two of equipment relatively movable parts and is connected with pipeline respectively, two relative movable parts of equipment are when certain limit is moved back and forth repeatedly, described piston rod is fore and aft motion in described piston sleeve, and movable part is in the conducting of travel range interior conduit and close groove location in described piston sleeve and the length of groove determines.
As further improved technological scheme, annular groove and lower annular groove are set on described piston rod, described upper orifice is arranged in described upper annular groove, and described lower nozzle is arranged in described lower annular groove.
The invention has the beneficial effects as follows: due to a kind of pipeline extension stroke valve of the present invention, piston rod is set in piston sleeve, piston sleeve top cavity volume is communicated with upper pipeline, lower nozzle in piston rod is communicated with lower pipeline, upper orifice in piston rod is communicated with the cavity volume of piston sleeve, on the inwall of piston sleeve middle part, groove is set, when piston rod moves in piston sleeve, when upper orifice and lower nozzle arrive groove simultaneously, upper orifice and lower nozzle could be communicated with.This pipeline extension stroke valve adopts piston rod fore and aft motion in piston sleeve realize the conducting of pipeline and close, simple in structure easy for installation, uses safety.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the another kind of scenario-frame schematic diagram of the present invention.
In figure each reference character containing meaning: 1. groove; 2. lower nozzle; 3. upper orifice; 4. go up pipeline; 5. piston sleeve; 6. piston rod; 7. descend pipeline; 8. go up annular groove; 9. descend annular groove.
Embodiment
As depicted in figs. 1 and 2, a kind of pipeline extension stroke valve, comprise piston sleeve 5 and piston rod 6, described piston rod 6 is set in described piston sleeve 5, described piston sleeve 5 top cavity volumes are communicated with upper pipeline 4, lower nozzle 2 in described piston rod 6 is communicated with lower pipeline 7, upper orifice 3 in described piston rod 6 is communicated with the cavity volume of described piston sleeve 5, on described piston sleeve 5 middle part inwalls, groove 1 is set, when described piston rod 6 moves in described piston sleeve 5, when described upper orifice 3 and described lower nozzle 2 all arrive described groove 1 place, described upper orifice 3 and described lower nozzle 2 could be communicated with.Annular groove 8 and lower annular groove 9 can also be set on described piston rod 6, and described upper orifice 3 is arranged in described upper annular groove 8, and described lower nozzle 2 is arranged in described lower annular groove 9.
Wherein, one end of described piston sleeve 5 and described piston rod 6 is mutually sheathed, the other end of described piston sleeve 5 and described piston rod 6 is separately fixed on two relative movable parts of equipment and is connected with pipeline respectively, two relative movable parts of equipment are when certain limit is moved back and forth repeatedly, described piston rod 6 is fore and aft motion in described piston sleeve 5, and movable part determines in the conducting of travel range interior conduit and groove 1 position and the length of closing in described piston sleeve 5.
During installation, the two ends of pipeline extension stroke valve of the present invention are screwed in respectively on the parts of two relative movement, then at two ends, connect hydraulic pressure or air-pressure duct.When two movable part relative movement, described piston rod 6 is fore and aft motion in described piston sleeve 5, when described upper orifice 3 and described lower nozzle 2 all arrive described groove 1 place, liquid or gas flow to lower nozzle 2 from lower pipeline 7 and enter in groove 1, by upper orifice 3, flow in upper pipeline 4, pipeline becomes on state again; When described upper orifice 3 and described lower nozzle 2 leave described groove 1 place, described upper orifice 3 and described lower nozzle 2 are cut off by described piston rod 6 and described piston sleeve 5, and now pipeline becomes closed condition.
