Technical field
The utility model relates to oil drilling equipment field, in particular to a kind of two position three way directional control valve with limit function of locking.
Background technique
When carrying out gas circuit maintenance, upkeep operation to oil-well rig, the accident that artificial misoperation can cause heavy economic losses even to injure life occurs, how to ensure that two position three way directional control valve is in the switching position of correct safety, to ensure to produce and the carrying out smoothly of regular maintenance, ensureing the life safety of maintenance man, is the significant problem that safety officer faces.
Model utility content
Technical problem to be solved in the utility model is, provides a kind of two position three way directional control valve preventing misoperation.
Therefore, the technical solution of the utility model is as follows:
There is a two position three way directional control valve for limit function of locking, comprise valve seat, spool, driveshaft and locking device, wherein:
Described spool is arranged in described valve seat, and described driveshaft is fixedly connected with described spool, for driving described valve core rotation thus switching between the first valve position and the second valve position;
Described locking device comprises upper collet, lower locking plate and positioning lock, described upper collet to be set on described driveshaft and to be connected with described driveshaft, described lower locking plate is fixedly mounted on described valve seat, described upper collet is provided with lockhole, described lower locking plate is provided with lower lockhole, when described driveshaft drives described valve core rotation to the first valve position, described upper collet turns to described upper lockhole with described driveshaft and aligns with described lower lockhole, when described positioning lock is used for that lockhole aligns with described lower lockhole on described and described on lockhole, described lower lockhole coordinates driveshaft described in fixing and locking.
Wherein, described positioning lock can be a padlock or bearing pin.
Having in the utility model is locked the two position three way directional control valve of limit function, and novel in design, unique, structure is simple, applied widely; Cheap for manufacturing cost, entirety can adopt aluminum alloy material to make, non-corrosive; Install simple, easy to operate, practical; The heavy economic losses that can effectively prevent misoperation from causing and personal injury, serve the effect prevented trouble before it happens.
Accompanying drawing explanation
Fig. 1 is the open mode schematic diagram with the two position three way directional control valve of limit function of locking according to the utility model embodiment;
Fig. 2 is the closed condition schematic diagram of the two position three way directional control valve in Fig. 1 with limit function of locking.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.It should be noted that, when not conflicting, the feature in the embodiment of the application and embodiment can combine mutually.
As depicted in figs. 1 and 2, according to the two position three way directional control valve with limit function of locking of embodiment of the present utility model, comprise valve seat 1, spool 12, driveshaft 2 and locking device, wherein:
Described spool 12 is arranged in described valve seat 1, and described driveshaft 2 is fixedly connected with described spool 12, for driving described spool 12 rotate thus switch between the first valve position and the second valve position;
Described locking device comprises upper collet 4, lower locking plate 7 and positioning lock (not shown), described upper collet 4 to be set on described driveshaft 2 and to be connected with described driveshaft 2, described lower locking plate 7 is fixedly mounted on described valve seat 1, described upper collet 4 is provided with lockhole 5, described lower locking plate 7 is provided with lower lockhole 6, when described driveshaft 2 drives described spool 12 to turn to the first valve position, (shown in Fig. 2 state) described upper collet 4 turns to described upper lockhole 5 with described driveshaft 2 and aligns with described lower lockhole 6, when described positioning lock is used for that lockhole 5 aligns with described lower lockhole 6 on described and described on lockhole 5, described lower lockhole 6 coordinates driveshaft 2 described in fixing and locking.
Wherein, described positioning lock can be a padlock or bearing pin.In addition, 10 be that suction port, 11 is for air outlet shown in figure.
Having in the utility model is locked the two position three way directional control valve of limit function, and upper collet 4 can be fixed on driveshaft 2 with on spool 12 by nut 3, and lower locking plate 7 can be coordinated by fixing bolt 9 and set screw nut 8 and be fixed on valve seat 1.When two position three way directional control valve is in the second valve position (opening position), control gas circuit and be communicated with, upper collet 4 is separated with lower locking plate 7, and atmosphere-comtrolling apparatus normally works; When atmosphere-comtrolling apparatus need repairing, safeguard time, two position three way directional control valve is controlled gas circuit to close, driveshaft 2 turns to the state shown in Fig. 2, upper lockhole 5 aligns with lower lockhole 6 and overlaps, and now positioning lock (as padlock or bearing pin etc.) directly can be passed from upper and lower keyhole (5,6) and can complete upper latching operation.
Having in the utility model is locked the two position three way directional control valve of limit function, and novel in design, unique, structure is simple, applied widely; Cheap for manufacturing cost, entirety can adopt aluminum alloy material to make, non-corrosive; Install simple, easy to operate, practical; The heavy economic losses that can effectively prevent misoperation from causing and personal injury, serve the effect prevented trouble before it happens.
In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present utility model, but this embodiment is included within scope of the present utility model.
