Abstract
The utility model proposes a kind of antiseep flat gate valves.The utility model on material guiding hopper by being arranged electromagnet, and permanent magnet is set on flashboard, and the position of electromagnet and permanent magnet just corresponds when flashboard is in the completely closed state, the magnetic force generated after being powered at this time by electromagnet attracts permanent magnet, so that flashboard is tightly pressed against on material guiding hopper, so that sealing is even closer, it overcomes flashboard cantilever design and is easy the problem of leaking when two sides pressure difference is larger, secondly, by the way that elastic sealing layer is arranged on flashboard, the pressing force of material guiding hopper is compressed by flashboard, so that the sealing between flashboard and material guiding hopper is even closer, leakage performance is stronger.
Description
Technical field
The utility model relates to a kind of antiseep flat gate valves.
Background technique
Applied to the flat gate valve in the fields such as powder, liquid, through-flow cut-off can be carried out by flashboard, but in flat gate valve
It usually will appear the problem of leakage when being chronically at closed state, at the cooperation of flashboard and valve body, especially in Flat Sluice
In the case that pressure difference between the inlet and outlet of valve is bigger, leakage is even more to happen occasionally.
Such as the Chinese patent that Authorization Notice No. is CN203098914U discloses a kind of flat gate valve, as shown in Figure 1, should
Flat gate valve includes valve body 1, flashboard 3 and flashboard driving device 2, and ram seal dress is provided with outside movement gap passage 13
It sets, flashboard 3 realizes the purpose of regulation openings of sizes by the cooperation with material guiding hopper 12, is chronically at closing in the flat gate valve
In the process, since flashboard is cantilever design, and the fluid pressure difference of flashboard two sides is bigger, for a long time, usually will appear lock
Bad sealing is close between plate and material guiding hopper and appearance the problem of leak, the automatic leakage of fluid bring sometimes it is extremely serious after
Fruit influences system security and stability.
Summary of the invention
The technical issues of the utility model proposes a kind of antiseep flat gate valves, effectively solve flat gate valve leakage.
The technical solution of the utility model is achieved in that antiseep flat gate valve includes that valve body, flashboard and flashboard drive
Dynamic device, valve body have inlet and outlet, are provided with material guiding hopper between inlet and outlet, material guiding hopper in miner diameter end inwardly, bigger diameter end court
To the tubaeform of setting, flashboard is slidably matched with miner diameter end, is provided on the conical surface towards flashboard setting outside the material guiding hopper
Electromagnet, flashboard is provided with towards material guiding hopper side when flashboard completely closes and the one-to-one permanent magnet of electromagnet, permanent magnetism
Iron phase fixes flashboard and the outer surface of permanent magnet is not higher than flashboard plane, and flashboard is towards also solid on the side side of material guiding hopper
Fixed flexible sealant.
Further, the elastic sealing layer in a ring, and its be arranged position flashboard close when and material guiding hopper path
End corresponds to.
Further, the permanent magnet is embedded on flashboard.
Further, the support for installing electromagnet is provided on the external conical surface of the material guiding hopper.
Further, support is connect by welding manner with material guiding hopper.
Further, electromagnet passes through bolt and support releasable connection.
Using above-mentioned technical proposal, the utility model has the following beneficial effects: the utility model on material guiding hopper by setting
Set electromagnet, and permanent magnet be set on flashboard, and when flashboard is in the completely closed state electromagnet and permanent magnet position
It sets and just corresponds, the magnetic force generated after being powered at this time by electromagnet attracts permanent magnet, so that flashboard is tightly pressed against
On material guiding hopper, so that sealing is even closer, the problem of flashboard cantilever design is easy leakage when two sides pressure difference is larger hair is overcome
It is raw, secondly, the pressing force of material guiding hopper is compressed by flashboard, so that flashboard and guide by the way that elastic sealing layer is arranged on flashboard
Sealing between bucket is even closer, and leakage performance is stronger.
