Description
Technical field
The present invention relates to valve field, in particular to a kind of novel rotary plug reversing valves.
Background technique
Rotary plug reversing valve (two-way valve) is the equipment for switching material direction in air-transport system.It can make material in pipeline
Change conveying direction under flow regime without interrupting feed and stopping gas supply, material is sent to two selected places.If
Material can be sent to many selected places by the conjunction of several valve groups, therefore operated with very convenient.It is widely used in flour, bran
Change in the positive/negative-pressure conveying of the powder grain materials such as chaff, starch, cereal, feed, sugar, chemical products, plastics and low speed transfer pipeline
Conveying direction makes material be sent to selected place.
The valve body of existing rotary plug reversing valve is the main body of equipment, there is a big hole among it, is provided with three on the wall of circular hole
A circular channel, respectively leads to a feed pipe and two discharge nozzles, and the spool of rotary plug reversing valve is also known as its outer diameter of cock and valve
The cooperation of body bore inner diameter is equipped with a radial passage for feed pipe and a straight-through discharge nozzle connection, Ling Yigen among spool
Oblique pass-out expects pipe is then in close state, and is pushed spur rack rotation by hydraulic or pneumatic compression devices, is made the biography engaged with spur rack
Moving gear drives valve core rotation to switch over material conveying direction.
But since the valve core rotation of rotary plug reversing valve carries out the switching of material conveying direction, when discharge nozzle and feed pipe
Axis not point-blank when (60 ° of usual deviation), material makes spool by the spool that will get excited when the radial passage of spool
Rotate (due to being positioned as hydraulic or pneumatic compression devices, liquid or gas may occur further to compress), and then material exports
Direction may again switch to another discharge nozzle, and material is caused to export unstable phenomenon.How to solve above-mentioned technical problem at
The direction made great efforts for those skilled in the art.
Summary of the invention
Based on problem above, the present invention provides a kind of novel rotary plug reversing valves.The present invention uses positioning device by spool
