Abstract
The utility model provides a compact inflation gate valve, includes flashboard subassembly, valve body, valve rod, disk seat, the flashboard subassembly includes main flashboard and vice flashboard, main flashboard vertical height is greater than vice flashboard, main flashboard up end with vice flashboard up end parallel and level sets up. The utility model discloses an expansion mechanism of inflation gate valve only comprises deflector and two parts of direction stopper of installing on the valve body, and the utility model discloses a gate valve expansion mechanism requires to reduce to part machining precision to reduce the requirement to assembly error, consequently reduced the gate valve cost.
Description
Technical field
The utility model relates to gate valve field, especially relates to a kind of expansion sluice valve field.
Background technique
Expansion sluice valve is as a kind of valve of pilot line break-make, because the advantage such as flow resistance is little, good seal performance, is widely used in every field.In prior art, the expansion mechanism of expansion sluice valve is mainly made up of rocking bar, bolt, nut, backplate etc., and number of spare parts is more, and it is higher that respective machining accuracy also all requires, and also has strict demand to assembly error, and therefore cost is higher.
Model utility content
In order to overcome the defect of prior art, the utility model provides following technological scheme:
A kind of compact type expansion sluice valve, comprise flashboard assembly, valve body, valve rod, valve seat, described flashboard assembly comprises main gate-board and auxiliary gate-board, described main gate-board vertical height is greater than described auxiliary gate-board, described main gate-board upper-end surface and the concordant setting in described auxiliary gate-board upper-end surface, described auxiliary gate-board lower end surface is exceeded bottom described main gate-board, described main gate-board and described auxiliary gate-board have relative set and the inclined-plane of working in coordination, described valve rod is connected with described main gate-board upper-end surface, also comprise guide plate, three links, described guide plate is provided with г guiding groove, one type through hole and two cylindrical holes, first link leads to through a described type, be connected with described valve rod, second link is connected with described main gate-board by the first cylindrical hole, 3rd link is connected with described auxiliary gate-board by the second cylindrical hole, described valve body is provided with guiding plug, described guiding plugs in described г guiding groove.
Further, described link is rivet.
Further, described valve seat and described flashboard assembly abutting end are provided with O type circle.
The expansion mechanism of expansion sluice valve of the present utility model is only filled in two parts by guide plate and the guiding be arranged on valve body and is formed, and gate valve expansion mechanism of the present utility model requires to reduce to part processing precision, and the requirement reduced assembly error, because this reducing gate valve cost.
