All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-5, the utility model provides a floating type sealing spectacle valve, which comprises an electric device 1, wherein the electric device 1 is in transmission connection with a worm wheel 14 of a clamping mechanism 3 through a transmission shaft and a speed reducer; a spring floating mechanism 5 is arranged between the pulling plate 10 of the clamping mechanism 3 and the main valve box 2; the valve plate 4 is positioned between a fixed valve seat and a movable valve seat 13 in the main valve box 2; the movable valve seat 13 is fixedly connected with the pull plate 10; a toothed pin 8 is fixed above the valve plate 4, a turning plate chain wheel 7 of the turning plate mechanism 6 is meshed with the toothed pin 8, and the turning plate chain wheel 7 rotates to drive the toothed pin 8 on the valve plate 4 so as to realize the transverse movement of the valve plate 4.
In some embodiments, the worm wheel 14 of the clamping mechanism 3 is in driving connection with the lead screw 15 (corresponding to a worm), the lead screw 15 passes through the connecting sleeve 16 in the pulling plate 10 and then is in threaded connection with the nut 17, and the nut 17 plays a role in limiting the movement of the pulling plate 10. The clamping mechanism 3 drives the screw rod 15 to move through the worm wheel 14, thereby pulling the pull plate 10 to drive the movable valve seat 13 to loosen the valve plate 4.
In some embodiments, two spring seats of the spring floating mechanism 5 are respectively fixed on the pull plate 10 and the main valve box 2, and the two spring seats are connected through a spring. When the valve plate 4 needs to be clamped, the clamping mechanism 3 drives the screw rod 15 to move towards the direction close to the valve plate 4 through the worm wheel 14, at the moment, the pull plate 10 also moves towards the direction close to the valve plate 4 under the action of the elastic force of the spring, and due to the limiting action of the nut 17, the pull plate 10 and the screw rod 15 synchronously move, and the pull plate 10 drives the movable valve seat 13 to press the valve plate 4, so that sealing is formed under the action of the sealing ring 11.
In some embodiments, a bellows 12 is provided on one side of the movable valve seat 13, and is retractable to provide a movable space for movement of the movable valve seat 13. The valve plate 4 is provided with a sealing ring 11 for sealing.
In some embodiments, the output end of the driving device of the plate turnover mechanism 6 is fixedly connected with the transverse moving shaft 9, and the plate turnover chain wheel 7 is sleeved and fixed on the transverse moving shaft 9. The driving device of the flap mechanism 6 drives the transverse moving shaft 9 to rotate, thereby driving the flap chain wheel 7 to rotate, and the flap chain wheel 7 drives the valve plate 4 to move through the transmission of the gear teeth and the gear pins 8.
The utility model has the following advantages:
1. on the basis of the original clamping mechanism of the glasses valve, the fixing mode between the clamping mechanism of the valve plate and the pulling plate is changed from a conventional relatively fixed mode into a relatively movable mode.
2. In order to achieve uniform sealing, the spring floating mechanism 5 is added, the mechanism can be arranged at will, the external leakage of the valve is not influenced, compared with the conventional relatively fixed form between the clamping mechanism 3 of the valve plate and the pull plate 10, the valve plate 4 is more favorable for uniform sealing, the external leakage point of the valve is reduced, the torque of a device for clamping the valve is reduced, the valve is simple and easy to operate, and the requirement on a master worker is low.
The working process of the utility model is as follows:
the electric device 1 reverses to drive the worm wheel of the clamping mechanism 3 to rotate, the worm wheel of the clamping mechanism 3 drives the lead screw 15 to move in a direction away from the valve plate 4, and the lead screw 15 of the clamping mechanism 3 pulls the connecting sleeve 16 welded with the pull plate 10 under the action of the nut, so that the pull plate 10 is driven, the movable valve seat 13 is far away from the valve plate 4, and the spring floating mechanism 5 is compressed at the moment and stores force. And then the electric assembly of the plate turnover mechanism 6 rotates to drive the plate turnover chain wheel 7 on the plate turnover mechanism 6 to drive the valve plate 4 to move through the tooth pin 8, so that the exchange of the blind holes of the valve plate 4 is realized. When the valve plate 4 is clamped, the electric device 1 on the transmission mechanism rotates positively, at the moment, the lead screw 15 does not push the pull plate 10, the force accumulated by the spring floating mechanism 5 when the valve plate 4 is loosened is released, the pull plate 10 is pushed to move towards the valve plate 4, and the pull plate 10 compresses the valve plate 4 at a constant speed under the obstruction of the nut 17 on the lead screw 15 through the connecting sleeve 16, so that the sealing effect is achieved. Because the spring floating mechanism 5 can be arranged at will, the spring floating mechanism 5 can give the pressing force at the position where the pull plate 10 is deformed, the effect that the valve plate 4 is uniformly sealed is achieved, the defect that the pull plate 10 is far away from the clamping point and the sealing is poor due to the fact that the pull plate 10 is deformed due to the fact that stress is concentrated is overcome, and due to the fact that the stress of the sealing position of the valve plate is uniform, the pressing force is greatly reduced, on one hand, the torque of the clamping device can be reduced, on the other hand, the condition that the stress of the sealing position is uneven is greatly improved, and the service life of the sealing ring is prolonged.
