Description
Technical field
The utility model relates to a kind of gate valve, specifically refers to a kind of contract formula gate valve with blowing mechanism.
Background technique
The oil products such as Wedge gate valve is widely used in petrochemical industry, thermal power plant, water vapour pipeline are connected or are blocked the start-stop device of pipeline medium.The structure of existing Wedge gate valve includes valve body, wedge shape flashboard, valve rod, valve gap and valve rod lift drive mechanism, runner is provided with in described valve body, described runner is at the both-side opening of valve body, and described valve body is provided with valve seat relative on runner, described wedge shape flashboard lifting is arranged in valve seat actively, and the upper end of this flashboard is fixedly connected with valve rod and coordinates.
When traditional wedge action valve is used in dust-containing airflow pipeline, the sealing surface between its wedge shape flashboard and valve seat is easy to the dirt that bonds, makes valve seal bad difficult with valve opening.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existed to overcome prior art, and provides one to have blowing mechanism, thus can carry out to the dirt of the sealing surface be bonded between wedge shape flashboard and valve seat the Wedge gate valve purging the band blowing mechanism cleaned.
For achieving the above object, the technical solution of the utility model includes valve body, wedge shape flashboard, valve rod, valve gap and valve rod lift drive mechanism, valve body is provided with inlet pipeline, outlet conduit and be positioned at inlet pipeline, valve seat between outlet conduit, described wedge shape flashboard lifting is arranged in valve seat actively, and the upper end of this wedge shape flashboard is fixedly connected with valve rod and coordinates, the bottom of described valve body opposite valve seat is provided with the first blowing mechanism, this first blowing mechanism includes and is arranged on valve body and the first purge hole communicated with body cavity, first purging inlet pipe of the outer end sealed attachment of this first purge hole, described first purges the first purging control valve inlet pipe being provided with and opening and closing for controlling the first purging inlet pipe.
Further setting is that the fillet position of described valve gap is provided with the second blowing mechanism, this second blowing mechanism includes and is arranged on valve gap and the second purge hole communicated with body cavity, second purging inlet pipe of the outer end sealed attachment of this second purge hole, described second purges the second purging control valve inlet pipe being provided with and opening and closing for controlling the second purging inlet pipe.
Further setting is that the first described purging control valve and the second purging control valve are hand sluice valve.
The utility model has the advantages that by arranging the first blowing mechanism and the second blowing mechanism, when occurring between the sealing surface between wedge shape flashboard and valve seat that dirt bonds, open the first purging control valve and second respectively and sweep control valve, first purging inlet pipe and second are purged inlet pipe open, carry out spraying into high-pressure wash water or pressurized purge gas in body cavity, realize cleaning the dirt at sealing surface place, the limited sealing also reduction keying resistance having ensured wedge-type flashboard.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
