Abstract
The utility model relates to a double-sluice plate valve. The utility model comprises an upper box body and a lower box body which are connected together through a connecter, a sluice plate opening and closing screw rod which is arranged on the upper end of the upper box body, and connecting pipes which are radially and symmetrically arranged on a pipe wall of the lower box body and are communicated with the cavity of the lower box body. Two connecting rods are hinged on the lower end of the sluice plate opening and closing screw rod. The other end of each of the two connecting rods is respectively provided with a valve plate which corresponds to the shape of the pipe port of each connecting pipe. The inner wall of the upper box body and the inner wall of the lower box body are provided with slide ways for the valve plates to move. Due to the adoption of the structure characteristics, no frictional force exists when a sluice plate glides down along the slide ways. Soft seal is realized on the valve plates and the service life of the valve plates is prolonged.
Description
The utility model relates to a kind of valve that is applicable to combustion gas, relates to a kind of double-flashboard valve specifically.
The structure of existing double-flashboard valve is the double disc parallel seat that is provided with an inverted U-shaped in the underpart of flashboard keying screw mandrel, when the needs throttle down, the double disc parallel seat that the operation flashboard opens and closes screw mandrel drive inverted U-shaped is displaced downwardly to the connecting tube nozzle position place that is arranged on the lower box tube wall, with the connecting tube ferrule, thereby reach the purpose of throttle down.Owing to be subjected to the restriction of above-mentioned double flap valve door, can only be firmly to hard sealing between the flashboard and the connecting tube mouth of pipe, sealing surface of valve plate will produce very big frictional force in folding process and between the connecting tube mouth of pipe, this has not only reduced the working life of valve plate, owing to contained granule foreign in the combustion gas is adsorbed on the sealing surface of valve plate, also caused simultaneously because of the not generation of tight gas leak phenomenon of connecting tube ferrule.
The purpose of this utility model provides a kind of double-flashboard valve with regard to being to overcome above-mentioned existing in prior technology deficiency, it has not only eliminated sealing surface of valve plate in folding process and the frictional force that is produced between the connecting tube mouth of pipe, also be beneficial to simultaneously the soft seal of sealing surface of valve plate, improved the sealing effect of valve plate.
The purpose of this utility model can realize by following technical measures:
The utility model comprises the upper and lower casing that combines by link, the flashboard that is arranged on the upper box upper end portion opens and closes screw mandrel, be arranged on the lower box tube wall with radial symmetric, and with the connecting tube of lower box intracavity inter-connection, it is characterized in that: open and close screw mandrel underpart at this flashboard and be provided with two connecting rods by hinged mode; Be respectively arranged with in the other end of described two connecting rods one with the corresponding valve plate of connecting tube orifice configuration; On upper and lower cabinet wall, offer and be used for the chute that valve plate moves.
Advantage of the present utility model just is that valve plate is opened and closed the screw mandrel underpart by connecting rod and flashboard to be hinged together, and last, offer on the lower box inwall and be used for the chute that valve plate moves, when throttle down, the operation flashboard opens and closes screw mandrel drive flashboard and moves down along chute, to the connecting tube nozzle position place that is arranged on the lower box tube wall, valve plate will move horizontally along horizontal concrete chute, under the support power effect of connecting rod, with the connecting tube ferrule, because flashboard does not contact with the casing tube wall and the connecting tube mouth of pipe when chute moves down, so there is not frictional force, not only realized the soft seal of valve plate, the working life of also having improved valve plate greatly simultaneously.
Fig. 1 cuts open figure for master of the present utility model.
The utility model describes in further detail below in conjunction with specific embodiment (accompanying drawing):
As shown in the figure, the utility model comprises the upper and lower casing 1,2 that combines by link, the flashboard that is arranged on upper box 1 upper end portion opens and closes screw mandrel 3, be arranged on lower box 2 tube walls with radial symmetric, and with the connecting tube 4,5 of lower box 2 intracavity inter-connections, open and close screw mandrel 3 underparts at this flashboard and be provided with two connecting rods 6,7 by hinged mode; Be respectively arranged with in the other end of described two connecting rods 6,7 one with the corresponding valve plate 8,9 of connecting tube 4,5 orifice configuration; On upper and lower casing 1,2 inwalls, offer and be used for the chute 10 that valve plate 8,9 moves.
