Abstract
A compact type expansion gate valve comprises a flashboard assembly, a valve body, a valve rod and a valve seat. The flashboard assembly comprises a main flashboard and an auxiliary flashboard. The vertical height of the main flashboard is larger than that of the auxiliary flashboard. The upper end face of the main flashboard is flush with the upper end face of the auxiliary flashboard. The bottom of the main flashboard is beyond the lower end face of the auxiliary flashboard. The main flashboard and the auxiliary flashboard are provided with bevels which are arranged correspondingly and are matched with each other. The valve rod is connected with the upper end face of the main flashboard. The compact type expansion gate valve further comprises a guide plate and three connection parts. The guide plate is provided with an r guide groove, a linear through hole and two cylindrical through holes. An expansion mechanism of the expansion gate valve only comprises the guide plate and a guide piston which is installed on the valve body, the requirements of the expansion mechanism of the compact type expansion gate valve for part machining precision are lowered, the requirements for assembly error is lowered, and thus the cost of the gate valve is reduced.
Description
Technical field
The present invention relates to gate valve field, more particularly, to a kind of expansion sluice valve field.
Background technology
Expansion sluice valve, because flow resistance is little, the advantages of good seal performance, is widely used in every field as a kind of valve of control piper break-make.The expansion mechanism of expansion sluice valve is mainly made up of rocking bar, bolt, nut, backplate etc. in prior art, and number of parts is more, and the comparison that respective machining accuracy is also required is high, and also has strict demand to rigging error, therefore relatively costly.
The content of the invention
In order to overcome the defect of prior art, the present invention to provide technical scheme below：
A kind of compact expansion sluice valve，Including flashboard assembly、Valve body、Valve rod、Valve seat，The flashboard assembly includes main gate-board and auxiliary gate-board，The main gate-board vertical height is more than the auxiliary gate-board，The main gate-board upper surface is concordant with the auxiliary gate-board upper surface to be arranged，The main gate-board bottom exceeds the auxiliary gate-board lower surface，The main gate-board and the auxiliary gate-board have relative set and the inclined-plane worked in coordination，The valve rod is connected with the main gate-board upper surface，Also include guide plate，Three connectors，The guide plate is provided with г gathering sills、One type through hole and two column type through holes，First connector is connected through the type through hole with the valve rod，Second connector is connected by the first column type through hole with the main gate-board，3rd connector is connected by the second column type through hole with the auxiliary gate-board，The valve body is provided with guiding plug，The guiding is plugged in the г gathering sills.
Further, the connector is rivet.
Further, the valve seat is provided with O-ring with the flashboard assembly abutting end.
Two parts of guiding plug of the expansion mechanism of the expansion sluice valve of the present invention only by guide plate and on valve body are constituted, and the gate valve expansion mechanism of the present invention requires part processing precision to reduce, and the requirement to rigging error is reduced, therefore reduce gate valve cost.
