The Vacuum interface valve is extremely suitable for negative-pressure transportation of the fluid.
Description
Technical field
The utility model relates to a kind of vacuum interface valve that is applied in the liquid negative pressure transportation equipment, and especially a kind of suction port biasing and guiding fluid of adopting rotates the vacuum interface valve that washes sealing surface.
Background technique
In the present liquid negative pressure transportation equipment, vacuum interface valve adopts a cylinder piston rod usually, drives black box by piston rod, carries out the action of open and close valve.
The Related product of existing technology adopts spherical sealing and plane sealing basically.And its suction port and outlet quadrature make fluid enter flowing state complexity behind the valve body, and velocity flow profile is extremely inhomogeneous, and some locally causes dirt to be deposited on sealing surface owing to liquid speed is low in the extreme situation lower sealing surface, thereby influences the performance of closing of valve.
Because sewage, the waste water of the reply of vacuum interface valve become increasingly complex, common valve body structure often deposits impurity at sealing surface easily, thereby influences the sealability of valve or even closing of valve.The reliability of vacuum interface valve is reduced, might cause that the most at last whole low-pressure drainage system is unreliable, even paralysis.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and guides fluid to rotate to wash sealing surface, the vacuum interface valve of the employing fluid rotation self-cleaning sealing surface of higher reliability when keeping using.
The technological scheme that provides according to the utility model, the vacuum interface valve of described employing fluid rotation self-cleaning sealing surface, be included in the valve casing that is provided with on the valve body, in valve body, be provided with valve pocket, valve body is provided with the valve inlet section that is communicated with valve pocket, the valve export section, the seal that has intermittent shutoff valve export section entry end at valve pocket, connect driveshaft on the seal, driveshaft stretches in the valve casing, be stained with barrier film at the valve casing inwall, the barrier film middle part is fixed on the driveshaft, make the valve casing inner space form two cavitys up and down, be provided with spring assembly between driveshaft upper end portion and the valve casing, be provided with the cylinder interface on the valve casing above the barrier film, described valve inlet section and valve pocket are eccentric and are provided with.
Be fixed with dunnage on the seal, seal is fixed on the driveshaft underpart by dunnage.Be fixed with mounting plate on driveshaft, the middle part of described barrier film is attached on the mounting plate.
Described spring assembly is included in the fixing lower magnet piece in driveshaft upper end portion, is provided with magnet piece on the valve casing inwall of driveshaft upper end portion correspondence, is provided with Returnning spring between valve casing inwall and mounting plate upper surface.
On the valve casing inwall, be provided with the concentrating flux sleeve that is placed in outside the magnet piece.Be provided with guide pipe in the valve casing bottom, described driveshaft sliding plug is in the guide pipe endoporus.
The utility model is arranged suction port by the side position, the fluid state that enters valve body is guided into rotational flow, thereby guarantee that valve body sealing surface and valve inner do not have dirt and accumulate, this mode is simple in structure, processing realizes easily, Returnning spring power was maximum and be unfavorable for the maintenance of this state having reduced this valve to vacuum requirements in the vacuum line when utilization of piston head magnet and cylinder bottom magnet had overcome valve wide open, and it is moved in the scope of the non-constant width of system vacuum degree.The utility model operation, reliability height, cheap for manufacturing cost is very suitable for the negative pressure transportation of liquid.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: the vacuum interface valve of described employing fluid rotation self-cleaning sealing surface, be included in the valve casing 13 that is provided with on the valve body 17, in valve body 17, be provided with valve pocket 18, valve body 17 is provided with the valve inlet section 15 that is communicated with valve pocket 18, valve export section 1, the seal 2 that has intermittent shutoff valve export section 1 entry end at valve pocket 18, connect driveshaft 4 on the seal 2, driveshaft 4 stretches in the valve casing 13, be stained with barrier film 12 at valve casing 13 inwalls, barrier film 12 middle parts are fixed on the driveshaft 4, make valve casing 13 inner spaces form two cavitys up and down, be provided with spring assembly between driveshaft 4 upper end portions and the valve casing 13, be provided with cylinder interface 11 on the valve casing above the barrier film 12 13, described valve inlet section 15 is eccentric with valve pocket 18 and is provided with.
Be fixed with dunnage 3 on the seal 2, seal 2 is fixed on driveshaft 4 underparts by dunnage 3.Be fixed with mounting plate 5 on driveshaft 4, the middle part of described barrier film 12 is attached on the mounting plate 5.
Described spring assembly is included in the fixing lower magnet piece 6 in driveshaft 4 upper end portions, is provided with magnet piece 8 on valve casing 13 inwalls of driveshaft 4 upper end portion correspondences, is provided with Returnning spring 9 between valve casing 13 inwalls and mounting plate 5 upper surfaces.
