The automatic flow control valve that the leakproofness is good includes: the valve comprises a valve body 1, wherein fixing plates 2 are fixedly connected between two sides of the top and two sides of the bottom of the inner wall of the valve body 1, through holes 3 are respectively formed in the two fixing plates 2, sealing gaskets 4 are respectively arranged on the opposite sides of the two fixing plates 2, the top fixedly connected with mounting groove 5 of 1 inner wall of valve body, equal sliding connection has sliding plate 6 between the positive both sides of mounting groove 5 inner wall and the both sides at the back, two spout 7 has all been seted up to sliding plate 6's inside, two the equal fixedly connected with connecting rod 8 in one side that sliding plate 6 leaves mutually, two the one end of connecting rod 8 all runs through mounting groove 5 and extends to the outside of mounting groove 5, two connecting rod 8 extends to the outside one end fixedly connected with closing plate 9 of mounting groove 5, two the equal fixedly connected with toper stopper 10 in one side that closing plate 9 leaves mutually.
The taper limiting block 10 is matched with the through hole 3, and the flow area of the through hole 3 can be changed through the arrangement of the taper limiting block 10, so that the flow is adjusted.
The top of valve body 1 is rotated and is connected with valve rod 11, the bottom of valve rod 11 runs through in proper order valve body 1 with mounting groove 5 extends to the inside of mounting groove 5, the bottom fixedly connected with rolling disc 12 of valve rod 11, two connecting blocks 13 of the bottom fixedly connected with of rolling disc 12, two connecting blocks 13 are sliding connection respectively in the inside of two spout 7.
The top end of the valve rod 11 is fixedly connected with a rotating handle 14, the rotating handle 14 is convenient for a user to rotate the valve rod 11, and the operation is more labor-saving.
A circular plate 15 is fixedly connected to the outer surface of the valve rod 11, and a groove 16 is formed in the outer surface of the circular plate 15.
The top of valve body 1 just is located the right side of valve rod 11 is provided with limit structure 17, limit structure 17 includes fixed slot 171, sliding connection has sliding block 172 between the top of fixed slot 171 inner wall and the bottom, the left side fixedly connected with lug 173 of sliding block 172, the left side of lug 173 is run through fixed slot 171 and extend to the left side of fixed slot 171, the right side fixedly connected with pull rod 174 of sliding block 172, the surface cover of pull rod 174 is equipped with reset spring 175, the other end of pull rod 174 runs through fixed slot 171 and extend to the right side of fixed slot 171.
The front surface of the protruding block 173 is of an arc-shaped structure, and the circular plate 15 can rotate towards the arc surface through the arc-shaped structure, and cannot rotate back to the arc surface, so that the circular plate 15 is clamped in a single direction.
The utility model provides an automatic flow control valve that leakproofness is good's theory of operation as follows:
the valve rod 11 is rotated by manually rotating the rotating handle 14 anticlockwise, so that the rotating disc 12 is rotated to drive the two connecting blocks 13 to do arc motion, and the two sliding plates 6 are moved away from each other by matching with the two sliding chutes 7, so that the two connecting rods 8 are driven to move away from each other, and the two sealing plates 9 are driven to move away from each other and abut against the two sealing gaskets 4 for sealing;
in the process of rotating the handle 14 counterclockwise, the circular plate 15 can rotate counterclockwise, and further the arc surface of the convex block 173 is extruded by the groove 16, so that the convex block 173 contracts, the return spring 175 is indirectly extruded, the return spring 175 resets due to the elastic force and drives the convex block 173 to extend, so that the convex block 173 is clamped into other grooves 16, because the back surface of the convex block 173 is a straight surface, the circular plate 15 cannot be reversed through the straight surface, so that the valve rod 11 cannot rotate reversely, after the convex block 173 contracts by manually pulling the pull rod 174, the groove 16 on the circular plate 15 is withdrawn, and the valve rod 11 can rotate reversely.
Compared with the prior art, the utility model provides an automatic flow control valve that leakproofness is good has following beneficial effect:
the valve rod 11 is rotated by manually rotating the rotating handle 14 anticlockwise, so that the rotating disc 12 is rotated to drive the two connecting blocks 13 to do arc motion, and the two sliding plates 6 are moved away from each other by matching with the use of the two sliding grooves 7, so that the two connecting rods 8 are driven to move away from each other, and the two sealing plates 9 are driven to move away from each other and abut against the two sealing gaskets 4 for sealing;
during the counterclockwise rotation of the handle 14, the circular plate 15 will be rotated counterclockwise, so that the groove 16 will press the arc surface of the protrusion 173, the protrusion 173 is contracted to indirectly press the return spring 175, and the return spring 175 is restored by the elastic force to drive the protrusion 173 to extend, so that the protrusion 173 is inserted into another groove 16, since the back surface of the protrusion 173 is a straight surface, the circular plate 15 cannot be rotated reversely by the straight surface, so that the valve stem 11 cannot be rotated reversely, after the pull rod 174 is pulled manually to enable the convex block 173 to shrink, the concave block 16 on the circular plate 15 is withdrawn, the valve rod 11 can rotate reversely, the safety of the valve is effectively ensured, after the valve is closed by rotating the valve rod 11, the valve rod 11 can be limited, so that the valve rod 11 cannot rotate reversely, the pull rod 174 needs to be pulled to rotate, and the valve rod 11 is prevented from rotating to open the valve under an unexpected condition.
The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
