Abstract

An air safety valve with a drying cylinder structure comprises a valve seat, a cylindrical valve rod and a valve core, wherein a connecting end of the valve seat is provided with a limiting block, the valve core is installed on a valve seat insert connected onto the valve seat through threads, and the center in the valve core is fixedly connected with the cylindrical valve rod. The tail end of the cylindrical valve rod is provided with a pressure adjusting valve block, a pressure spring is sleeved outside the cylindrical valve rod, a baffle block is arranged on the inner wall of the valve seat at the front end of the pressure adjusting valve block, and a triangular air hole is arranged on the lateral wall of the valve seat and located on the inner side of the pressure adjusting valve block. The air safety valve with the drying cylinder structure has the advantages that the pretightening force of the pressure spring at the position of the valve rod is adjustable, and a work pressure interval of the whole safety vale can be adjusted through adjustment of the pretightening force of the pressure spring; the triangular air hole enables the safety valve to release pressure more quickly with bigger pressure in the pressure releasing process, and pressure balance in a drying cylinder controlled by the safety valve can be quickly guaranteed.

Description

technical field

[0001] The invention relates to an air safety valve with a dryer structure, which belongs to the field of dryer equipment in the dyeing and finishing industry, and is used for preventing negative pressure inside the dryer and preventing water vapor from overflowing inside the dryer. Background technique

[0002] Drum dryers can be divided into three types: vertical type, horizontal type and bridge type according to the arrangement of the drying drum.

[0003] The vertical drum dryer is the most widely used drum dryer in the dyeing and finishing process. There are several types such as single column, double column, three column and concave column, which can be selected according to the actual process requirements. There are 8, 10 or 12 drying cylinders installed on each pair of columns. For this kind of equipment for drying polyester-cotton blended fabrics, the last 3 drying cylinders should be changed to cooling rollers, otherwise, 2 to 3 cooling rollers sh...
