Abstract
The utility model relates to a valve structure, in particular to a retractable flexible sealed butterfly valve, which comprises a valve seat and a valve spool. A hollow flexible sealing ring is arranged in the valve spool, a cavity of the hollow flexible sealing ring is communicated with an external air compression device of the butterfly valve by the aid of an inflating hole and a ventilating channel arranged inside the valve spool, and a groove is disposed on the inner surface, which corresponds to the hollow flexible sealing ring, of the valve seat. The valve is light and convenient in opening and closing and flexible in operation, reliability of the valve is improved, and the service life of the valve is prolonged.
Description
Technical field
The utility model relates to a kind of valve mechanism, particularly relates to a kind of flexible sealing formula butterfly valve that moves back of throwing.
Background technique
Existing reed valve generally adopts the rigidity spool, and for bigbore butterfly valve, the operational torque that the rigidity spool needs is very big, and the flexibility of valve switch and reliability are not high.Being used to carry the large-diameter butterfly valve of liquid, in order to satisfy the requirement of this class valve switch flexibility and reliability, generally is to adopt to throw the rigid seal body that moves back, and during valve operation, withdraws from seal earlier, then the switch butterfly valve; After butterfly valve cuts out fully, drop into seal again; For the butterfly valve that is used for the Air-cooled Unit blow-off line, its main feature one is that differential pressure is little, less than 0.1MPa, the 2nd, bore is big, and general diameter is all greater than 1000mm, can throw the sealing configuration that moves back if adopt rigidity, can make butterfly valve structure too complicated, if adopt traditional rigidity spool, the leakproofness of valve is difficult to be guaranteed, because the operational torque that needs is big, the flexibility of valve switch and reliability are just not high.
The model utility content
The purpose of this utility model provides a kind of flexible sealing formula butterfly valve that moves back of throwing, and makes valve switch light, flexible operation, the reliability of raising valve.
The technological scheme that the utility model is taked is: the utility model comprises valve seat and spool, be provided with the hollow flexible seal ring in the described spool peripheral groove, the inner chamber of hollow flexible seal ring is connected with the pressurized air control gear of described butterfly valve outside by air-filled pore and the breather line that is arranged in the spool.
The internal surface of the utility model and the corresponding valve seat of hollow flexible seal ring is provided with groove.
The beneficial effects of the utility model are: valve seat of the present utility model adopts conventional metal seat valve, the sealed member of spool adopts flexible material (as rubber) as seal, throwing by inflation venting realization seal is moved back, during the butterfly valve operation, venting earlier, withdraw from seal, be convenient to alleviate the moment of butterfly valve operation, make the flexible operation of butterfly valve reliable; After butterfly valve cuts out fully,,, guarantee that butterfly valve is definitely tight with the seal input to the seal inflation.
Description of drawings
Fig. 1 is that seal of the present utility model drops into the status architecture schematic representation;
Fig. 2 is a seal exit status structural representation of the present utility model.
In the drawings, 1 valve seat, 2 hollow flexible seal rings, 3 spools, 4 vents, 5 grooves, 6 breather lines.
Embodiment
The utility model comprises valve seat 1 and spool 3, is provided with hollow flexible seal ring 2 in the spool 3, and the material of hollow flexible seal ring 2 can be rubber material.The inner chamber of hollow flexible seal ring 2 through vent 4 and and the breather line 6 that is arranged in the spool be connected with the pressurized air control gear of butterfly valve outside, the pressurized air control gear can charge and discharge gas to hollow flexible seal ring 2.The internal surface of the valve seat 1 corresponding with hollow flexible seal ring 2 is provided with groove 5, and groove 5 preferred numbers are two.Air-filled pore 4 is arranged on spool 3, and the breather line 6 by spool 3 makes the pressurized air control gear inflate hollow flexible seal ring 2 and exit.During operation, hollow flexible seal ring 2 is withdrawed from venting earlier, to protect hollow flexible seal ring 2 and to be convenient to alleviate the moment of butterfly valve operation of the present utility model, makes the flexible operation of butterfly valve reliable, as shown in Figure 2.After butterfly valve cut out fully, to 2 inflations of hollow flexible seal ring, as shown in Figure 1, hollow flexible seal ring 2 expanded to be pressed on the valve seat 1.Groove 5 on the valve seat 1 is used to improve the leakproofness of butterfly valve, guarantees that butterfly valve is definitely tight.Valve switch of the present utility model is light, and flexible operation has improved the reliability and the leakproofness of valve.
Claims (2)
1. can throw the flexible sealing formula butterfly valve that moves back for one kind, comprise valve seat (1) and spool (3), it is characterized in that, be provided with hollow flexible seal ring (2) in described spool (3) peripheral groove, the inner chamber of hollow flexible seal ring (2) is connected with the pressurized air control gear of described butterfly valve outside by air-filled pore (4) and the breather line (6) that is arranged in the spool.
2. the flexible sealing formula butterfly valve that moves back of throwing according to claim 1 is characterized in that being provided with groove (5) with the internal surface of the corresponding valve seat of hollow flexible seal ring (2) (1).
