Abstract

The utility model discloses a combined device capable of indicating the opening degree of a valve and a locking valve, which is characterized in that screw thread and a groove arranged on a valve rod are respectively connected with a pointer (3) and a movable valve rod (7). The pointer (3) is restricted in a notch of a scale cover (4) so that the pointer cannot rotate and only can make up-and-down movement to indicate the opening degree of the valve. A handwheel support base (6) is sheathed on the scale cover (4) through a cylindrical pin (5), a lock screw (10) arranged in the handwheel support base (6) is fixed by a grip ring (9), and the square movable valve rod (7) with a protruding key is arranged to make up-and-down movement through the lock screw (10) and is connected with the groove on the upper portion of the valve rod (1), thereby achieving opening and locking the valve.

Description

Valve opening indication and locking composite set
Technical field:
The utility model belongs to the technical field that machinery is made, and is specifically related to a kind of valve opening indication and locking composite set, is applicable to the use of valve manufacturing.
Background technique:
Known to the inventor, in the smaller diameter valve (gate valve) of dark bar, generally there is not the valve opening indicating device, just do not know that in use whether valve switch reaches the valve opening size, brings inconvenience to practical operation; 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 opening indication and the locking composite set that can know that valve opening can be controlled by operator that provides.
The utility model is achieved in that the structure of a kind of valve opening indication and locking composite set is, valve rod (1) is set is connected with valve gap (2) with trip ring, is connected with pointer (3) with screw thread on it; One graduating cover (4) is set to be connected with valve gap (2), pointer (3); Handwheel supporting base (6) is set to be enclosed within on the graduating cover (4) by straight pin (5), the lock bolt (10) that the polygon side of one odd number is set in it is fixing with clamping back-up ring (9), a square protruding key of being with is set again moves valve rod (7), rely on lock bolt (10) to move up and down, be connected with the groove on valve rod (1) top, realize valve opening and locking; Handwheel (8) is fixed on the handwheel supporting base (6).
The utility model cardinal principle is by screw thread spiral motion to be become straight line motion to indicate the valve opening size; The groove by the protruding key on the mobile valve rod (7) and valve rod (1) top of moving up and down by square mobile valve rod (7) breaks away from and contacts locking and the unlatching that realizes valve.
Valve opening; Rotate counterclockwise lock bolt (10) with Key jaw type spanner (11), square mobile valve rod (7) moves downward, the protruding key of mobile valve rod (7) is entered in the groove on valve rod (1) top, rotate its moment of handwheel (8) and drive valve rod (1) rotation by handwheel supporting base (6) and mobile valve rod (7), make flashboard move up and down the opening and closing valve, valve is in opening state; When valve rod (1) rotated, pointer (3) only moved up and down under the threaded function of valve rod (1) owing to can not rotate by the restriction of graduating cover (4) and indicates valve opening.
The valve locking; Clockwise rotate lock bolt (10) with Key jaw type spanner (11), square mobile valve rod (7) moves upward, the groove that makes the protruding key of mobile valve rod (7) break away from valve rod (1) top, rotate handwheel (8) this moment, handwheel supporting base (6) and mobile valve rod (7) are along with handwheel (8) rotates together, and the valve rod transfixion, valve is in lockup state.
It is directly perceived that valve opening indication of the present utility model and locking composite set have the aperture indication, 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, pointer; 4, graduating cover; 5, straight pin; 6, handwheel supporting base; 7, mobile valve rod; 8, handwheel; 9, clamp back-up ring; 10, lock bolt; 11, Key jaw type spanner.
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 screw thread to be set on valve rod (1) to be connected pointer (3) and mobile valve rod (7) respectively with groove as shown in drawings.Pointer (3) is limited in the notch of graduating cover (4), can not rotate also to move up and down; Move valve rod (7) with protruding key. in having the handwheel supporting base (6) of handwheel (8), rely on lock bolt (10) to move up and down with square sleeve, break away from the groove on valve rod top and contact realization valve opening and locking.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)

1. the structure of valve opening indication and locking composite set is, valve rod (1) usefulness trip ring is set is connected with valve gap (2), it is characterized in that being that on valve rod (1) top screw thread being set is connected pointer (3) and mobile valve rod (7) respectively with groove.
2. valve opening indication as claimed in claim 1 and locking composite set is characterized in that being to be provided with pointer (3) is limited in the notch of graduating cover (4).
3. as claim 1,2 described valve opening indication and locking composite sets, it is characterized in that being to be provided with handwheel supporting base (6) passes through straight pin (5) rotation set on graduating cover (4), the lock bolt (10) that the polygon side of one odd number is set in it is fixing with clamping back-up ring (9), a square mobile valve rod (7) is set again, relies on lock bolt (10) to move up and down.
