Description

Gate valve lock pin control device

The utility model relates to the gate valve lock control devices, particularly a kind of gate valve lock pin control device.

Transport in the material process at pipeline, often to use gate valve, close or open pipeline, and many valves are unattended, can are arbitrarily closed or open by the people, influence normally transporting of material, in order to address this problem, the someone has invented gate valve with lock, in order to the lock-up valve door-hinge, make the people can not arbitrarily open or close valve, but also there is following shortcoming in this valve with lock: 1, keyhole is easily blocked by foreign material; 2, the key storage difficulty is big, and easily loses; 3, change gate valve expense height with lock.

The purpose of this utility model is that design is a kind of without key, need only the rotational password dish, make it to meet predefined password, gate valve lock pin control device that just can the control sluice threshold switch.

The technical solution of the utility model is achieved like this: gate valve lock pin control device, it is characterized in that it is made up of overhead guard, several concentric rotating disk handwheels, flanged (FLGD) inner ring, ring gear, locating ring, pressing plate and bearing, ring gear is with replacing screw in overhead guard, have tooth mouth and teeth groove on the ring gear, there is the gate valve axis hole at flanged (FLGD) inner ring center, on its flange installing hole is arranged, bearing is contained in the interior dead eye of flanged (FLGD) inner ring, pressing plate is threaded with flanged (FLGD) inner ring upper end, and the annulus boss is arranged on the pressing plate; Several concentric rotating disk handwheels are contained in the outer annular groove of flanged (FLGD) inner ring, and all concentric with flanged (FLGD) inner ring, and several concentric rotating disk handwheels all can rotate mutually, and the inner ring axis of energy strip winding flange rotates; On several concentric rotating disk handwheels double wedge is arranged all, double wedge stretches in the teeth groove on the ring gear, and locating ring is contained on the outermost rotating disk handwheel, to limit the position that overhead guard falls, on overhead guard and the rotating disk handwheel,, all be carved with the digital calibration line on overhead guard and the rotating disk handwheel to limit a position that cover falls.

The gate valve lock pin control device that the utility model provides, to several concentric rotating disk handwheels be housed, gate valve axis hole on flanged (FLGD) inner ring of locating ring is inserted on the gate valve axle, with bolt the flange on flanged (FLGD) inner ring is fixed on the gate valve seat, load onto the gate valve handwheel, again pressing plate is threaded with flanged (FLGD) inner ring upper end, at this moment the figure on the pressing plate encircles boss and pushes down the gate valve handwheel, double wedge on the rotating disk handwheel that several are concentric transfers to same straight line, with the double wedge on corresponding several rotating disk handwheels of the tooth mouth on the ring gear in the overhead guard, be pressed into overhead guard to the locating ring place, rotating overhead guard and several rotating disk handwheels just can pin gate valve, as need the utility model is opened, as long as with overhead guard, combination of numbers on several concentric rotating disk handwheels is corresponding to predefined password, and at this moment overhead guard just can be transferred to, and takes off pressing plate, promptly rotatable gate valve handwheel, to open or closing gate valve, the utility model compared with prior art has the following advantages: 1, need not to use key, do not exist foreign material to block keyhole; 2, need not the keeping key; 3, need not to change original gate valve.
