The utility model has the advantage that misoperation induced by touching the handle incautiously in working process could be effectively avoided.
Description
Technical field
The utility model relates to a kind of pneumatic element, specifically a kind of locking device of hand-operated direction valve.
Background technique
Hand-operated direction valve is a kind ofly to come the selector valve of control flows port with hand, and its feature is not need the power control part branch, and the work field boundary that is suitable for the hand-guided commutation closes.But the location of common hand-operated direction valve relies on spring to add steel ball and realizes that its feature is that reliability of positioning is poor, and handle is done the time spent and can be produced commutation running into unexpected external force, causes the misoperation of valve, thereby produces safety problem.This closes at safe field boundary and has just brought fatal defective.
The model utility content
Purpose of design of the present utility model provides a kind of locking device of safe, reliable, easy to operate hand-operated direction valve.
Its main technical schemes is at the middle part of handle hinging shaft to be arranged, and utilizes the hinged stop pin of bearing pin at an end of handle, at the other end of handle Returnning spring is set.
The middle part of handle utilizes hinging shaft to be connected with the valve body cover plate, on the valve body cover plate pin-and-hole is set, and in the pin-and-hole of stop pin seat, and can move up and down in pin-and-hole; One end of Returnning spring embeds in the groove on the handle, and the other end embeds on the valve body cover plate in the corresponding groove; After stop pin passes pin-and-hole in the valve body cover plate, can insert the bayonet socket on the center valve body that is positioned at below the valve body cover plate, center valve body is connected with following valve seat.
Connecting body is installed in inside at the valve body cover plate, import is set in valve seat, bottom in center valve body is provided with rotary spool, two commutation grooves that can be communicated with import are set in the bottom of spool, connecting body is connected with spool after passing center valve body, and between spool and connecting body spring is set.
In the lower end surface of valve body cover plate the arcuate guide groove is set, guide finger is set on center valve body, the upper end of guide finger is positioned at the arcuate guide groove, and can slide in the arcuate guide groove.
The utility model has the advantages that owing on hand-operated direction valve, be provided with locking framework, when not needing rotating valve, stop pin in this locking framework can insert in the bayonet socket on the center valve body, the valve body cover plate can't be rotated relative to center valve body, can't drive valve core rotation, selector valve is in the lock state, thereby has avoided effectively in the working procedure because of running into the misoperation that handgrip occurs because of carelessness.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Embodiment
As shown in the figure: utilize hinging shaft 10 to be connected at the middle part of handle 9 with valve body cover plate 6, end at handle 9 utilizes bearing pin 8 hinged stop pins 7, be provided for Returnning spring 12 that handle 9 is upwards resetted at the other end of handle 9, to guarantee that the stop pin 7 on the handle 9 often is in the lock state, has only when the time stop pin 7 state that just can go out of lock by lower handle 9.On valve body cover plate 6 pin-and-hole is set, stop pin 7 is positioned at pin-and-hole, and when pressing active handle 9, stop pin 7 just can be upper and lower mobile in pin-and-hole.As a kind of fairly simple means of fixation, one end of Returnning spring 12 can embed in the groove 21 that is arranged on the handle 9, the other end then embeds and is arranged on the valve body cover plate 6 in the corresponding groove 22, after stop pin 7 passes pin-and-hole in the valve body cover plate 6, can insert the bayonet socket on the center valve body 5 that is positioned at below the valve body cover plate 6, when the lower end of stop pin 7 is inserted in the bayonet socket, valve is in the lock state, make valve body cover plate 6 to rotate relative to center valve body 5, center valve body 5 is connected with following valve seat 2.
Connecting body 16 is installed in inside at valve body cover plate 6, and fluid inlet 20 is set in valve seat 2, and the bottom in center valve body 5 is provided with and can the commutation groove 18,19 that can be communicated with import 20 be set in the bottom of spool 4 with the spool 4 of connecting body 16 rotations.When rotational valve core 4, import 20 just can be communicated with commutation groove 18 or commutation groove 19 respectively, or be not communicated with commutation groove 18,19, being as the criterion and determining the position, the position of above-mentioned bayonet socket should accurately be set, when guaranteeing that stop pin 7 inserts certain bayonet socket, just in time be that import 20 is communicated with certain commutation groove, or obstructed position, bayonet socket should be provided with 3 usually, correspond respectively to commutation groove 18 19 or with commutation groove 18,19 whole obstructed positions, specifically definite by required station.Connecting body 16 passes center valve body 5 backs and is connected with spool 4, and connecting body 16 plays a part to connect valve body cover plate 6 and spool 4, and connecting body 16 can rotate in center valve body 5.Between spool 4 and connecting body 16, spring 17 is set, fit together tightly with the lower end surface of guaranteeing spool 4 and the upper-end surface of valve seat 2, in the lower end surface of valve body cover plate 6 the arcuate guide groove is set, guide finger 14 is set on center valve body 5, the upper end of guide finger 14 is positioned at the arcuate guide groove, and can in the arcuate guide groove, slide, when valve body cover plate 6 rotated around the center of connecting body 16, guide finger 14 played good leading role.
For avoiding leaking, at valve seat 2 and 5 of center valve bodies and connecting body 16 and 5 of center valve bodies seal ring 3 is set respectively, 15, among the figure 1,11 difference bolts, 13 for being used to rotate the handgrip of valve body cover plate 6, during use, grasp handgrip 13 and handle 9, make handle 9 move down pressure spring 12, the other end of handle then moves up, drive on the stop pin and move, make the lower end of stop pin break away from bayonet socket on the center valve body, at this moment just can rotate the valve body cover plate, the valve body cover plate drives connecting body and valve core rotation again, when valve core rotation is communicated with import to certain commutation groove, release handle, stop pin just in time inserts corresponding bayonet socket under the effect of spring, and the valve body cover plate is pinned, after the pinning, even run into handgrip because of carelessness, the valve body cover plate is rotated, thereby play safety effect.
