Abstract
The utility model belongs to the technical field of the desiccator blow -off valve, a desiccator blow -off valve of novel structure is related to, in particular to vacuum target formula desiccator blow -off valve, the major structure includes valve plug, valve body, valve rod, tank connection valve, flap valve, cylinder connecting rod, valve plug fastening valve, gas hole, locking cylinder, sealing washer, the desiccator jar body and the pump of blowing, its valve plug and valve body all adopt the design of double containment circle, have guaranteed the leakproofness of desiccator, through setting up the pump cooperation of blowing of gas hole and outside on the valve body, the material residue on valve plug and the sealing washer all sweeps when closing the valve plug at every turn, effectively avoid material cross contamination, the life who has increased the sealing washer has also improved sealing performance the while, its overall structure is simply firm, and sealed effectual, design principle is reliably understandable, prepare with low costs, application environment friendly.
Description
Technical field:
This utility model belongs to drying machine blow-off valve technical field, relate to the drying machine blow-off valve of a kind of new structure, particularly to a kind of vacuum target formula drying machine blow-off valve, gas purging will be compressed to valve plug surface and sealing ring surface by gas hole, the material adhered to will be purged the effect totally realizing maintenance drying machine cleaning and sealing.
Background technology:
Drying machine is a kind of plant equipment utilizing heat energy to reduce material moisture, for object is dried operation, drying machine is by heating hygroscopic water (referring generally to moisture or other volatile liquid components) the vaporization effusion made in material, to obtain the solid material of regulation moisture content, dry in order that the material needs that use or be processed further, for involving a need to the material sealed and cleaning is dry, it is requisite for especially relating to the material being dried in vacuum environment, better seal environment and more robust sealing structure.In the prior art, the commonly used hard sealing of blow-off valve seal form or sealing ring used by current drying machine seal, hard sealing is higher to machining accuracy and the movement needs of parts, slightly deflection may result in seal failure, sealing ring seal form simple in construction, good sealing effect, but in discharging process, material is easily adhered on sealing surface and sealing ring, thus affecting sealing effectiveness and causing that the service life of sealing ring shortens.Therefore, design a kind of novel vacuum rake dryer blow-off valve and there is good economic benefit and social benefit.
Summary of the invention:
Goal of the invention of the present utility model is in that to overcome the shortcoming of prior art, seek to design a kind of vacuum target formula drying machine blow-off valve, gas purging will be compressed to valve plug surface and sealing ring surface by gas hole, the material adhered to will be purged the effect totally realizing maintenance drying machine cleaning and sealing.
The vacuum target formula drying machine blow-off valve that this utility model relates to, agent structure includes valve plug, valve body, valve rod, tank body connection valve, flap valve, cylinder connecting rod, valve plug fastening valve, gas hole, locking cylinder, sealing ring, drying machine tank body and blower pump；The valve plug of ring-type integrative-structure is fixedly installed on the drying machine tank interior upper end open place of cylindrical structure, and the valve body outer end of ring-type integrative-structure is connected by tank body connection valve is fixing with drying machine tank body spiral, and the inner has multiple gas hole；Valve rod is connected by valve plug fastening valve is fixing with valve plug spiral, flap valve is fixedly installed drying machine tank body, the inside of drying machine tank body is fixing with the right-hand member of valve rod to be connected, and is connected with the locking cylinder rotary type being arranged on dryer cans external body by cylinder connecting rod, in order to open and close valve plug；Blower pump is fixedly installed on the outer end of inflatable mouth；The bottom of the sealing ring of four ring-type integrative-structures one group of the inner being separately positioned on valve body and valve plug between two, in order to fit sealing valve body and valve plug.
When this utility model uses, locking cylinder elongated dynamic air cylinder connecting rod rotates thus driving flap valve to rotate so that valve rod rotates down, and the valve plug being fixed on valve rod is followed and moved downward, to open drying machine tank body；When closing tank body, locking cylinder shrinks band dynamic air cylinder connecting rod and flap valve opposite direction rotates, valve rod and valve plug are moved upward and covers drying machine tank body, when close to sealing station, compression gas enters gas hole by blower pump, purging valve plug surface and sealing ring surface, purged by the material of its adhesion clean, then valve plug is closed.
Compared with prior art, valve plug and valve body all adopt Double seal ring to design to this utility model, it is ensured that the sealing of drying machine；Being coordinated with outside blower pump by the gas hole being arranged on valve body, all purge the material residue on valve plug and sealing ring when closing valve plug every time, be prevented effectively from material cross-contamination, the service life adding sealing ring also improves sealing property simultaneously；Its overall structure is simply firm, good sealing effect, and design principle is reliably understandable, and preparation cost is low, and applied environment is friendly.
Accompanying drawing illustrates:
Fig. 1 is the structural principle schematic diagram of the vacuum target formula drying machine blow-off valve that this utility model relates to.
Detailed description of the invention:
It is further described by the examples below and in conjunction with accompanying drawing.
Embodiment 1:
The vacuum rake dryer blow-off valve that the present embodiment relates to, its agent structure includes valve plug 1, valve body 2, valve rod 3, tank body connection valve 4, flap valve 5, cylinder connecting rod 6, valve plug fastening valve 7, gas hole 8, locking cylinder 9, sealing ring 10, drying machine tank body 11 and blower pump 12；The valve plug 1 of ring-type integrative-structure is fixedly installed on the drying machine tank body 11 inner upper end opening part of cylindrical structure, and valve body 2 outer end of ring-type integrative-structure is connected by tank body connection valve 4 is fixing with drying machine tank body 11 spiral, and the inner has multiple gas hole 8；Valve rod 3 is connected by valve plug fastening valve 7 is fixing with valve plug 1 spiral, flap valve 5 is fixedly installed drying machine tank body 11, the inside of drying machine tank body 11 is fixing with the right-hand member of valve rod 2 to be connected, and be connected with locking cylinder 9 rotary type being arranged on outside drying machine tank body 11 by cylinder connecting rod 6, in order to open and close valve plug 1；Blower pump 12 is fixedly installed on the outer end of inflatable mouth 8；The bottom of the sealing ring 10 of four ring-type integrative-structures one group of the inner being separately positioned on valve body 2 and valve plug between two, in order to fit sealing valve body 2 and valve plug 1.
