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
The present invention relates to a kind of drying cylinder structural gap safety valve, belong to the cylinder drying machine apparatus field of dyeing and finishing industry, be used to prevent drying cylinder inner generation negative pressure and prevent that the drying cylinder internal steam is excessive.
Background technique
Cylinder drying machine can be divided into vertical, horizontal by the arrangement mode of drying cylinder and three kinds of bridge-types.
Vertical cylinder drying machine is the most widely used a kind of cylinder drying machine in the present dyeing and finishing processing.Several types such as single-column, twin columns, three posts and recessed post are arranged, can require to select for use according to actual process.Quantity be installed be 8,10 or 12 s' drying cylinder on every column.For this equipment of fabrics such as drying polyester cotton blending, last 3 drying cylinders should change the cooling roller into, otherwise, to add 2～3 cooling rollers at last, to reduce the temperature of fabric, prevent that fabric from producing permanent wrinkle.
Horizontal cylinder drying machine, the damp-heat air that when the drying fabric, is produced eliminating easily distribute the unlikely drying ability that influences other drying cylinders.Install, overhaul, wear cloth and operate all more convenient.But because occupation area of equipment is bigger, so less use.
The bridge-type cylinder drying machine is the hybrid drying machine that vertical and horizontal two kinds of drying machines are formed, and its maximum characteristics are compact structures.But it gets rid of comparatively difficulty of damp-heat air, so that other two kinds of force rates of drying ability are low, and complex structure, and installation, maintenance and operation are all inconvenient.Therefore, in dyeing and finishing processing, seldom use.
The drying cylinder structure is the groundwork mechanism in the drying machine, and drying cylinder inside will be full of steam usually, need discharge to the external world at vapor condensation Cheng Shuihou; Usually the red copper structure drying cylinder that adopts adopts siphon arrangement to discharge, but because syphon tube itself can not be controlled steam, can not play the effect of anti-overflow; So usually need be at siphonal outside gas control switch of installing; If but existing gas switch reaches accurate control, can only adopt electronic equipment at present, but electronic equipment lost efficacy easily under the environment of high temperature; And the cost of electronic equipment own is high, is inappropriate for a large amount of uses in the drying cylinder structure.
Summary of the invention
The technical problem that the present invention will solve is that the electrical air switch that overcomes existing drying cylinder structure lost efficacy and the high problem of the cost of electronic equipment own under high temperature condition easily, and the adjustable stainless steel drying cylinder of a kind of asymmetric balance structure is provided.
In order to solve the problems of the technologies described above, the invention provides following technological scheme:
Drying cylinder structural gap safety valve comprises valve seat, column valve rod, spool, and the connecting end of valve seat is provided with limiting stopper; Said spool is installed on valve seat inserts, and valve seat is inserted through being threaded on the valve seat, and the central interior of spool is fixedly connected with the column valve rod; The end of column valve rod is equipped with the pressure regulator valve piece; And being connected to pressure spring in column valve rod outer cover, conflicts respectively on pressure regulator valve piece and valve seat are inserted in the two ends of said pressure spring, and the valve base inner wall of said pressure regulator valve piece front end is provided with block; Being used for restriction pressure modulating valve piece gets loose and drops; And the elastic force that prevents pressure spring when excessive the pressure regulator valve piece get in the inner syphon tube of valve seat, have the triangle pore at the sidewall of said valve seat, and said triangle pore is positioned at the inboard of pressure regulator valve piece.
Drying cylinder structural gap safety valve provided by the invention, its beneficial effect is that the pretightening force of the pressure spring at valve rod place is adjustable; Can adjust the working pressure interval of whole safety valve through the pretightening force at adjustment pressure spring place; And adopt leg-of-mutton pore can make safety valve in the process of pressure release, and pressure is big more, and pressure release is fast more; Also just can guarantee the drying cylinder internal pressure balance that safety valve is controlled faster, better than the effect of common air-break switch.
Description of drawings
Accompanying drawing is used to provide further understanding of the present invention, and constitutes the part of specification, is used to explain the present invention with embodiments of the invention, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is the structural drawing of drying cylinder structural gap safety valve of the present invention.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for explanation and explains the present invention, and be not used in qualification the present invention.
As shown in Figure 1, drying cylinder structural gap safety valve of the present invention comprises valve seat 1, column valve rod 9, spool 3; The connecting end of valve seat 1 is provided with limiting stopper 8; Said spool 3 is installed in valve seat and inserts on 2, and valve seat inserts 2 through being threaded on the valve seat 1, and the central interior of spool 3 is fixedly connected with column valve rod 9; The end of column valve rod 9 is equipped with pressure regulator valve piece 5; And being connected to pressure spring 4 in column valve rod 9 outer cover, conflicts respectively and inserts on 2 at pressure regulator valve piece 5 and valve seat in the two ends of said pressure spring 4, and the valve base inner wall of said pressure regulator valve piece front end is provided with block 7; Being used for restriction pressure modulating valve piece 5 gets loose and drops; And the elastic force that prevents pressure spring 4 when excessive pressure regulator valve piece 5 get in the inner syphon tube of valve seats, have triangle pore 6 at the sidewall of said valve seat, and said triangle pore 6 is positioned at the inboard of pressure regulator valve piece 5.
Drying cylinder structural gap safety valve provided by the invention, its beneficial effect is that the pretightening force of the pressure spring at valve rod place is adjustable; Can adjust the working pressure interval of whole safety valve through the pretightening force at adjustment pressure spring place; And adopt leg-of-mutton pore can make safety valve in the process of pressure release, and pressure is big more, and pressure release is fast more; Also just can guarantee the drying cylinder internal pressure balance that safety valve is controlled faster, better than the effect of common air-break switch.
