Abstract
The utility model relates to a type-changing sluice valve, comprising a valve body, flashboards, a bolt head, a pushing and pulling board, a screw rod, and a gear, wherein, the screw rod is connected with the pushing and pulling board and the bolt head; the screw rod transmits depending on a gear; the operation is flexible and labor saving. Pressure to flashboards at both sides of the bolt head is generated by the bolt head; the sealing performance enhanced; the abrasion of a sealing surface in the process of opening and closing the flashboards are eliminated; the service life of the sluice valve is increased; the phenomenon of falling weight is put in one end; the cost is saved. The utility model is a novel sluice valve with high performance.
Description
The utility model relates to a kind of remodeling gate valve, is applicable to the Flow-rate adjustment control of gas, liquid, belongs to mechanical device.
At present, flashboard in the prior art in the used gate valve is directly to be connected with the screw rod that promotes flashboard, the closely connected realization Gate-valve sealing of flashboard and sealing surface, there is very big frictional force between flashboard and the sealing surface, causes the suffered pulling force of screw rod very big, cause the sealing surface abrasion big, switch gate effort, and can not deal with cut-out or open operation under the state of emergency, also easily fall stone roller, easily interior the leakage.
The utility model is in order to overcome above-mentioned deficiency, and provides a kind of flashboard top that the tongue prefix is housed, and the good gate valve of sealing usefulness that promotes by screw rod, gear of tongue prefix.
Concrete technological scheme of the present utility model is: this gate valve comprises valve body, flashboard, tongue prefix and pushing-pulling-plate, screw rod, gear, valve gap is equipped with on valve body top, be contained in the middle handwheel bottom of valve gap and adorn a small gear, little gear wheel and gearwheel engagement, gearwheel center and screw rod are affixed, the screw rod bottom is connected with pushing-pulling-plate and tongue prefix, the width of tongue prefix is greater than the minimum separable between flashboard, pushing-pulling-plate links to each other with flashboard by link press span, one section no mercerising sliding surface is arranged at the screw rod bottom, between valve gap and the valve body top sealing plate is housed, is with sealing seat on the screw rod, the screw rod bottom is stuck in the axle bowl groove of valve body wall.
Characteristics of the present utility model are: the lifting of flashboard is by gear transmission, flexible operation is laborsaving, owing to increased the effect of tongue prefix, making does not almost have kinetic force of friction between flashboard sealing surface and the valve body sealing surface, eliminated the wearing and tearing to sealing surface in switching process of original flashboard, strengthens sealability, that has stopped gate valve falls to cut or polish jade with an emery wheel phenomenon, the service cycle of gate valve is increased, in the working life of having improved gate valve greatly, saved substantial contribution.
Concrete structure of the present utility model is provided by accompanying drawing 1-3.
Fig. 1 is the overall structure schematic representation of remodeling gate valve.
Fig. 2 is the plan view of remodeling gate valve tongue prefix.
Fig. 3 is the plan view of remodeling gate valve tongue prefix.
Main structure is among the figure: valve body 1, flashboard 2, tongue prefix 3, pushing-pulling-plate 4, screw rod 5, gear 6, valve gap 7, handwheel 8, link press span 9, no mercerising sliding surface 10, sealing plate 11, sealing seat 12, axle bowl 13, valve port 14.
Below in conjunction with accompanying drawing the utility model is described in detail.
This remodeling gate valve, comprise valve body 1, flashboard 2, tongue prefix 3 and pushing-pulling-plate 4, screw rod 5, gear 6, valve gap 7 is stamped on valve body top, be contained in middle handwheel 8 bottoms of valve gap and adorn a small gear, the gearwheel engagement of small gear and both sides, gearwheel center and screw rod are affixed, the screw rod bottom is connected with pushing-pulling-plate and tongue prefix, the Extreme breadth of tongue prefix is greater than the minimum separable between two flashboards, link to each other with flashboard by link press span 9 on the pushing-pulling-plate, flashboard has the gap apart from valve body sealing surface, one segment length is arranged at the screw rod bottom is the no mercerising sliding surface 10 of pushing-pulling-plate thickness, between valve gap and the valve body top sealing plate 11 is housed, by band sealing seat 12 on the screw rod of sealing plate bottom, the screw rod bottom is stuck in the axle bowl 13 of valve body wall.
Be contained in pushing-pulling-plate and tongue prefix on the screw rod at interval during assembling, need to rotate earlier handwheel when closing flashboard, handwheel drive small gear turns to by gearwheel drive screw rod pushing-pulling-plate and tongue prefix is moved downward along screw rod, when pushing-pulling-plate moves on to no mercerising position of slip surface, flashboard just blocks the valve port 14 of valve body, be rotated further handwheel this moment again, and screw rod will drive the tongue prefix to be continued to move down, until tongue prefix top till both sides flashboard generation pressure maximum.When flashboard need be opened in off position, this moment counterrotating handwheel again, the tongue prefix is earlier to rising, when the tongue prefix after withdraw between two flashboards, when pushing up pushing-pulling-plate, make pushing-pulling-plate enter the screw rod screw thread and drive flashboard and rise.This gate valve can be designed tandem product according to different nominal diameters.
