Abstract
The utility model discloses a valve locking device which is characterized in that a valve rod (1) is connected with a movable block (7) through a convex key arranged on the valve rod; an upper valve rod (6) is connected with the movable block (7) through a square key (8); a spring (10) is arranged between the upper valve rod (6) and the movable block (7); an outer sleeve of the valve locking device is arranged in the locking pressure cover (4); a handwheel (11) is arranged on the outer sleeve and is fixed by a screw (12); a key screw (9) whose upper part is a convex regular trilateral figure is connected with the movable block (7); a special key is threaded through the screw hole on the upper part of the valve rod (6) to rotate the key screw (9). The key screw (9) is rotated, so that the movable block (7) can move up and down to realize the insertion and separation of the convex key on upper part of the valve rod (1) and the concave groove of the movable block (7); thereby, the unlocking and locking functions of the valve are realized.
Description
Technical field:
The utility model belongs to the technical field that machinery is made, and is specifically related to a kind of valve locking apparatus, is applicable to the use of valve manufacturing.
Background technique:
Known to the inventor, when the line transportation medium, whether it supplies with the flow size and should be controlled by operator, can arbitrarily operate and common valve is for anyone.
Summary of the invention:
The purpose of this utility model is exactly above not enough for solving, and a kind of valve locking apparatus that can control by operator that provides.
The utility model is achieved in that a kind of structure of valve locking apparatus is, valve rod (1) is set is connected with valve gap (2) with O type circle (3) with divided ring (5); Valve rod (1) is set to be provided with a protruding key on it and to be connected with movable block (7); Its interior square key (8) that passes through of upper valve rod (6) is set is connected, and spring (10) is placed between upper valve rod (6) and the movable block (7) with movable block (7); Its outer being enclosed within the locking gland (4), also fixing on it with screw (12) by dress handwheel (11); One top is set is connected with movable block (7) with the key screw (9) of protruding positive triangle, and from the screw of upper valve rod (6) top with special key turns key screw (9).
The utility model cardinal principle is by screw thread spiral motion to be become straight line motion to come the protruding key by the groove on the movable block (7) and valve rod (1) top of moving up and down of mobile movable block (7) to break away from and contact the locking of realizing valve and unblank.
Valve is unblanked; Turn on the set screw (12) of handwheel (11), rotate counterclockwise key screw (9) with key (13), treat that key screw (9) twists when motionless, when rotating handwheel (11) to certain position, movable block (7) moves downward under spring (10) effect, the protruding key in valve rod (1) top is entered in the groove of movable block (7), rotate its moment of handwheel (11) this moment and drive valve rod (1) rotation by upper valve rod (6), square key (8) and movable block (7), make flashboard move up and down the opening and closing valve, valve is in unlocking condition.
The valve locking; Turn on the set screw (12) of handwheel (11), clockwise rotate key screw (9) with key (13), movable block (7) move up the groove that makes the protruding key in valve rod (1) top throw off movable block (7) treat key screw (9) twist motionless till, rotate handwheel (11) and the valve rod transfixion this moment, and valve is in lockup state.
Valve locking apparatus of the present utility model has simple in structure, and locking is reliable, and is easy to operate.
Description of drawings:
Accompanying drawing is valve opening indication and locking composite set structural drawing
Among the figure: 1, valve rod; 2, valve gap; 3, O type circle 4, locking gland; 5, divided ring 6, upper valve rod; 7, movable block; 8, square key; 9, key screw; 10, spring; 11, handwheel; 12, screw; 13, key.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing embodiment, and valve opening indication and locking composite set are as shown in drawings, valve rod (1) is set is connected with valve gap (2) with O type circle (3) with divided ring (5); Valve rod (1) is set to be provided with a protruding key on it and to be connected with movable block (7); Its interior square key (8) that passes through of upper valve rod (6) is set is connected, and spring (10) is placed between upper valve rod (6) and the movable block (7) with movable block (7); Its outer being enclosed within the locking gland (4), also fixing on it with screw (12) by dress handwheel (11); One top is set is connected with movable block (7) with the key screw (9) of protruding positive triangle, and from the screw of upper valve rod (6) top with special key turns key screw (9).Key screw (9), movable block (7) move up and down the groove of realizing protruding key in valve rod (1) top and movable block (7) and insert and disengaging, thereby realize unblanking and locking of valve.The utility model is specially adapted to smaller diameter valve (inside screw non-rising stem type gate valve) factory and forms a complete production network.
Claims (3)
