Abstract
The invention relates to a seal ring locking-type gate valve. The seal ring locking-type gate valve comprises a lifting rod, a flashboard, a seal ring, a locker, a locker driving device, a valve body and a driving device, wherein the flashboard is slidably arranged in the valve body, the flashboard is connected with one end of the lifting rod, and the other end of the lifting rod is connected with the driving device; the locker is controlled by the locker driving device and is slidably arranged on the valve body, and the locker is movably provided with the seal ring. Compared with the prior art, the seal ring locking-type gate valve has the advantages of being steady in sealing property, long in service life and low in operating cost.
Description
Technical field
The present invention relates to a kind of gate valve, particularly relate to a kind of seal ring locking gate valve being convenient to safeguard, compared with prior art, operating cost is low, easy to maintenance, and sealability is stablized.
Background technique
In recent years, based on the Large-scale High-Pressure conveying equipment for fluid substances of diaphragm pump, mortar pump, slurry pump, in application in industrial automation, development rapidly, especially in remote granule fluid transportation art, served very important key effect, and gate valve is crucial corollary equipment indispensable in the output pipe of these conveying equipment for fluid substances.Because existing gate valve seal failure is fast, difficult in maintenance, in use change frequent, operating cost is high, is one of current anxious equipment to be modified.Up to now, there is no sealability and stablize, easy to maintenance, and significantly can reduce the ideal product of operating cost.
Summary of the invention
The present invention is directed to above-mentioned present situation, through carefulness development and repetition test, design a kind of seal ring locking gate valve, solve sealability in prior art unstable, safeguard inconvenient, the difficult problem that operating cost is high.
Technological scheme of the present invention is as follows:
Comprise lifting bar, leading truck, flashboard, seal ring, locker, locker drive unit, valve body and drive unit; Gate panel slide is arranged in valve body, and flashboard is connected with one end of lifting bar, and the other end of lifting bar is connected with drive unit; Locker is slidably arranged on valve body by locker drive unit, and on locker, activity arranges seal ring.
Advantageous effect of the present invention is as follows:
1, be provided with seal ring that is for convenience detach, that change, when seal ring is worn to when can not normally use, replacing spare part can be pulled down.
2, be provided with locker, on locker, activity arranges seal ring.Work as Open valve, locker band seal ring moves axially along pipeline, first leaves flashboard liner plate sealing surface, rises flashboard afterwards, not only light but also can not abrade seal ring when guaranteeing that flashboard rises.Work as throttle down, first flashboard landing put in place, locker band seal ring moves axially along pipeline afterwards, is pressed on flashboard liner plate sealing surface, not only light but also can not abrade seal ring when guaranteeing that flashboard falls, and obtains stable sealing effect.
3, sealability is stablized, and operating cost is low.Life-span is long, easy to maintenance.
