Abstract
The utility model relates to a hydraulic rotary blade anti-theft stop valve. A casing is provided with a medium inlet and a medium outlet, and the interior of the casing is provided with a movable valve sheet and a fixed valve sheet which are coaxial; the movable valve sheet and the fixed valve sheet are provided with covering through holes which are corresponding; the periphery of the movable valve sheet is provided with gear teeth engaged with piston rack bars in a hydraulic piston cavity. As a valve gate of the utility model can be opened by using a special hydraulic power opening device, the phenomenon of random opening is prevented; in addition, the utility model has better anti-breaking and anti-theft performances, and is particularly suitable for the fields where the medium stealing phenomenon can easily occur, such as an oil field, etc.
Description
The utility model relates to the antitheft stop valve of a kind of hydraulic pressure rotary sheet type, belongs to valve field.
Existing valve is varied, as ball valve, gate valve, butterfly valve or the like, and the Lever type that its switching mechanism employing exposes, hand-wheel-type, gear type etc., thereby be very easy to be unlocked and dismantle destruction.This a lot of serious problems will occur in some field, as on the oil field, with regard to often valve is stolen in appearance, Open valve is stolen the phenomenon of oil voluntarily, and is hard to guard against, can't take precautions against.
The purpose of this utility model is to provide a kind of normal antitheft stop valve of opening of hydraulic pressure rotary sheet type that is difficult for.
The antitheft stop valve of hydraulic pressure rotary sheet type described in the utility model, there is medium to import and export on the housing, be provided with coaxial moving valve plate and fixed valve plate in the housing, moving valve plate and fixed valve plate are provided with the screening through hole of mutual correspondence, the periphery of its moving valve plate is provided with driving cog, and the piston-rack in the hydraulic piston is meshed with driving cog on the moving valve plate.
This valve need promote piston with hydraulic power unit and move, and piston drives moving valve plate again and rotates, and makes that the screening through hole of moving valve plate and fixed valve plate is overlapped to communicate or block mutually, realizes the complete opening of valve or closes fully; When the screening throughhole portions of moving valve plate and fixed valve plate is overlapping, can realize that the part of valve is opened or partly closed, to adjust rate-of flow.The unlatching of the utility model valve need be used specific hydraulic power opener, has prevented the generation of random unlatching phenomenon.
For simplified structure, improve application performance, moving valve plate only is provided with driving cog at the position with the piston-rack engagement and gets final product.
Parts contact position in the valve housing is provided with seal ring, to improve sealability.
The utility model has adopted the tight structure of integral sealing, has prevented to apply the damage of external force effect, cooperates valve to use the welding manner that connects again, can further strengthen performance tamper-proof, theft protection.
Below in conjunction with embodiment's accompanying drawing the utility model is further described.
Fig. 1, the utility model one embodiment's structural representation.
The A-A schematic cross-section of Fig. 2, Fig. 1.
Among the figure: lower shell body set screw, 18 moving valve plates hide through hole on 1 upper shell, 2,4,9 seal rings, 3 teflon spacers, 5 moving valve plates, 6 pistons, 7 fixed valve plates, 8 bearing pins, 10 setting circle pins, 11 control mouthful special-shaped screw plugs, 12 piston plugs, 13 piston cavity, 14 driving cogs, 15 tooth bars, 16 lower shell bodys, 17.
As shown in the figure, the antitheft stop valve of hydraulic pressure rotary sheet type described in the utility model, there is medium to import and export on the housing, be provided with coaxial moving valve plate 5 and fixed valve plate 7 in the housing, moving valve plate 5 and fixed valve plate 7 are provided with the screening through hole 18 of mutual correspondence, the periphery of its moving valve plate 5 is provided with driving cog 14, and the piston-rack 15 in the hydraulic piston 13 is meshed with driving cog 14 on the moving valve plate 5.Moving valve plate 5 only is provided with driving cog 14 at the position with piston-rack 15 engagements, and the parts contact position in the housing is provided with seal ring 2,4,9.Mouthful special-shaped screw plug of control 11 is sealed the cleaning of protection piston cavity hydraulic channel with piston cavity.
During use, the utility model is welded on the use position.In the time of need opening valve, use manual hydraulic device to give the piston upper chamber fuel feeding, piston moves from top to bottom, and piston-rack drives moving valve plate and clockwise rotates, and makes screening throughhole portions on moving valve plate and the fixed valve plate or overlapping fully, then valve part or complete opening; Give piston cavity of resorption fuel feeding, piston moves from bottom to top, and piston-rack drives moving valve plate and rotates counterclockwise, and the screening through hole on moving valve plate and the fixed valve plate is blocked mutually, then valve closing.
The unlatching of the utility model valve need be used specific hydraulic power opener, is difficult for normal the unlatching, has prevented the generation of random unlatching phenomenon.And adopted the tight structure of integral sealing and firm welding connecting mode, improved tamper-proof, theft protection performance.Suiting in the oil field etc. to be prone to the stolen field of medium especially uses.
