Abstract
The utility model relates to a multi-outlet selecting valve for pneumatic conveying, which can guarantee the sealing performance and can simultaneously prevent inflating annular sealing rings at pipe ports, which are made of elastic material, from damage. An annular sealing ring made of rigid material is arranged between the annular sealing ring made of elastic material and a cover plate at an outlet end, so that in the pipe line conversion process, even if a control circuit and electrical elements fail, the inflating annular sealing ring made of elastic material can not be damaged when no air exhausts, and the heavy labor generated during the replacing process of the inflating annular sealing ring made of elastic material, and the economic losses can be avoided.
Description
The utility model relates to a kind of multiple exit apolegamy valve of the conversion mass transport pipeline that uses in air-transport system, especially relate to a kind ofly adopting the elastic material O-ring seal to charge into pressurized air on the connecting tube mouth of pipe to realize the multiple exit apolegamy valve that seals rotating.
At present, the known rotation connecting tube mouth of pipe adopts the structure of the multiple exit apolegamy valve of elastic material O-ring seal gas-flow closure mainly to be made up of valve chest, rotation connecting tube, entrance point attachment portion, outlet end attachment portion, the O-ring seal of mouth of pipe elastic material and mounting blocks thereof etc.The filling of elastic material O-ring seal, exhaust and the rotation of connecting tube are realized by the control circuit that retarding braking motor and solenoid valve etc. are formed.In the work, when needing conversion mass transport pipeline, make the solenoid valve action by control circuit, discharge the pressurized air in the O-ring seal of mouth of pipe elastic material, connecting tube is rotated in the braking of unclamping motor, realize the pipeline aligning location of preliminary election by position limit switch and control circuit after, O-ring seal is inflated to elastic material again, the sealing delivery line, thus be implemented in conveying material in another pipeline.
But, the mouth of pipe O-ring seal that elastic material is made directly contacts with the outlet end cover plate, in case control circuit or electrical apparatus element break down, the not exhaust of pipeline when conversion solenoid valve, then the gas-filled annular seal ring made of elastic material will be compressed that air is extruded mounting groove and explosion or broken by strand.The sealing of delivery line also just can not realize, changes O-ring seal and then needs detaching pipelines connecting tube and end cap, and workload is very big.
The purpose of this utility model provides a kind of at the multiple exit apolegamy valve that rotates employing elastic material O-ring seal gas-flow closure on the connecting tube mouth of pipe.Line seal when it can realize conveying material reliably can be avoided when pipeline is changed the damage of the O-ring seal that causes when breaking down because of control circuit or electrical apparatus element again.
The purpose of this utility model is achieved in that the rigid material O-ring seal that a smooth abrasion-proof is arranged between gas-filled annular seal ring that elastic material is made and outlet end cover plate.The gas-filled annular seal ring that O-ring seal that rigid material is made and elastic material are made is installed in the same groove, during the conversion pipeline and outlet end cover plate generation relative movement be the O-ring seal that rigid material is made.Therefore, even control circuit or electrical apparatus element break down and cause not exhaust of solenoid valve in the pipeline transfer process, the gas-filled annular seal ring that elastic material is made also can not be extruded groove and explosion or twist bad.The pipeline conversion finishes, after rotating connecting tube and outlet end connecting tube aligning location, the rigid material O-ring seal is fitted on the smooth mating face of outlet end cover plate under the effect of elastic material gas-filled annular seal ring compressed air tightly, realizes the sealing to the conveying material pipeline.
Owing to adopt such scheme, can when utilizing pressurized air to realize the conveying material line seal, avoid the damage of the gas-filled annular seal ring of elastic material making again to elastic material O-ring seal inflation.And only be before elastic material gas-filled annular seal ring, to adopt a rigid material O-ring seal, simple in structure, easy to implement.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural drawing of multiple exit apolegamy valve of the present utility model.
Fig. 2 is an embodiment's of the present utility model sectional structural map.
In Fig. 1, entrance point connecting tube (2) is directly installed on the valve chest (1), at outlet end cover plate (5) plural at least outlet end connecting tube (4) is installed.Rotation connecting tube (3) one end and flange plate (15) thereof are supported on the outlet end cover plate (5) by minor axis (6), and the other end then directly is supported on the valve chest (1), thereby realize rotating.
In Fig. 2, ferrule circle mounting blocks (7) is fastened on the flange plate (15) that rotates connecting tube (3) by bolt (8).Elastic material gas-filled annular seal ring (11) is fixed in the groove of ferrule circle mounting blocks (7) by hold-down ring (13) and screw (9).The effect of gas circuit pipe joint (10) is pressurized air to be imported and discharges elastic material gas-filled annular seal ring (11).Rigid material O-ring seal (12) and elastic material gas-filled annular seal ring (11) are installed in the same groove, during the conversion pipeline, both together rotate in company with rotating connecting tube (3), and what contact with outlet end cover plate (5) is rigid material O-ring seal (12).Because the protective action of rigid material O-ring seal (12), even in the pipeline transfer process, control circuit or electrical apparatus element break down, and fill, the exhaust action makes a mistake, and elastic material gas-filled annular seal ring (11) can not be damaged yet.After the pipeline conversion finishes, elastic material gas-filled annular seal ring (11) is charged into pressurized air, and under compressed-air actuated effect, rigid material O-ring seal (12) and outlet end cover plate (5) fit tightly, realization guarantees the normal conveying of material to the sealing of delivery line.
For making the pipe (3) that is rotationally connected more stable in rotation process, between flange plate (15) and rotation connecting tube (3), be provided with a strut (14).
Rigid material O-ring seal of the present utility model (12) can be adopted material such as asbestos, plastics or copper.
Claims (1)
1, a kind of multiple exit apolegamy valve is included in the entrance point connecting tube (2) that valve chest (1) entrance point is installed; Outlet end cover plate (5) at the outlet end of valve chest (1); Go up the plural at least outlet end connecting tube of installing (4) at cover plate (5); One is rotatably installed in rotation connecting tube (3) and flange plate (15) thereof on the cover plate (5) by minor axis (6), rotation connecting tube (3) one end is connected with entrance point connecting tube (2), and the other end is installed in a side of the flange plate (15) that rotates connecting tube (3); A ferrule circle mounting blocks (7) that is fixed on said flange plate (15) opposite side, said mounting blocks (7) has a through hole that communicates with rotation connecting tube (3), reach and the groove that centers on said through hole, a fixed installation elastic material gas-filled annular seal ring (11) in groove, a breathing pipe communicates with elastic material gas-filled annular seal ring (11); It is characterized in that, in above-mentioned groove, a rigid material O-ring seal (12) is installed in the lower end of elastic material gas-filled annular seal ring (11).
