The flexible valve clack check valve is composed of main structures of a fixing body, an upper channel feed inlet, a sealing gasket, a lower channel feed inclined block, a flexible valve clack, an abrasion-resistant steel plate and the like. The flexible valve clack check valve is an important guaranty to determine performances, qualities and reliability of a semi-automatic sticked explosive conveyor, current home gaps and market gaps of sticked explosive conveyors for mining and hole drilling mining of mines can be compensated, and the flexible valve clack check valve which is a key part of a mine shot hole semi-automatic sticked explosive conveyor can increase the working efficiency.
Description
Technical field:
Cylinder material strength is carried and to be usingd the position control valve door of pressurized air as power.
Background technique:
Domestic at present, mine, tunnel and all Geotechnical Engineerings are utilized explosive, the make a sudden snatch borehole of made of cutting into a mountain is carried stick dynamite inwards, manufacturing process is all to utilize manually to throw in stick dynamite in borehole, because the particular location of borehole divides 360 each orientation of degree up and down, have the borehole of required explosion, laying explosive is the work that several individuals cooperatively interact and just can complete; If the deep situation of borehole also will be used long waddy, with manpower, stick dynamite is disclosed to deep end position; Be very effort, time-consuming, Fei Rengong, working efficiency is very low.
Can increase work efficiency and can reliably stick dynamite be placed to required position with a kind of equipment, and can save manpower, staff is freed from heavy manual labor, Zhe Shi Geotechnical Engineering circle be desirable; So a kind of mine borehole of increasing work efficiency is carried the semi-automatic conveyor of stick dynamite, can realize the desirable hope of Geotechnical Engineering circle, one of them is exactly a kind of flexible flap check valve for critical component in the semi-automatic conveyor mechanism of stick dynamite, and a kind of flexible flap check valve is the important leverage that determines the semi-automatic conveyor performance quality of stick dynamite and reliability.
Summary of the invention:
The object of the invention is to make up the perforating of opening a mine of current mine and open a mine and carry the domestic blank of stick dynamite machinery and the vacancy in market, provide a kind of mine borehole of increasing work efficiency to carry needed critical component in the semi-automatic conveyor mechanism of stick dynamite: a kind of flexible flap check valve.
A kind of flexible flap check valve, a flexible flap check valve, is comprised of fixed body, compressed air inlet, screw fixed hole, lower channel feed skewback, the fixing perforation of bolt, outer fixedly annular groove, lower channel opening, sealing gasket, flexible flap, upper channel material inlet, wear-resisting steel plate, upper channel feed skewback, closure gasket groove, the fixing perforation of bolt;
Its feature, fixed body endoporus has been fixed upper channel feed skewback, lower channel feed skewback, between upper channel feed skewback and lower channel feed skewback, gripped flexible flap, the wear-resisting steel plate of size size between the internal diameter of upper channel feed skewback and the internal diameter of lower channel feed skewback 4 that flexible flap upper surface is bonding, on the inclined-plane of upper channel feed skewback, a bonding outside dimension is slightly less than the lower channel opening upper-end inner diameter of lower channel feed skewback and the sealing gasket of the upper channel material inlet internal diameter that internal diameter size is slightly larger than upper channel feed skewback, closure gasket groove is to install after seal ring, is connected and fixed hopper as seal action, screw fixed hole, the fixing perforation of bolt, the fixing perforation of bolt are to be connected and fixed above hopper and the fixedly conduit effect of fixed body, lower channel feed skewback, upper channel feed skewback and the material channel below lower channel opening, outer fixedly annular groove gives over to fixing peripheral component support, and compressed air inlet is to realize connecting flexible flap, the wear-resisting steel plate of controlling flexible flap check valve, and the press seal that loosens of upper channel feed skewback institute adhering and sealing pad is changed the vent to gas and disappointing function, when: cylindrical material enters upper channel material inlet with certain speed, and wash flexible flap open, wear-resisting steel plate, at this moment in the passage of lower channel opening, lose heart, cylindrical material continues to come downwards to be controlled while loosening press seal throw over switch machine-operated, the office of throw over switch turns at once, to contracting air intlet inflation one, be that air pressure has compressed flexible flap, wear-resisting steel plate, the 2nd, make air pressure promote cylindrical material continuation acceleration descending, when the integral body of cylindrical material is during through throw over switch machine-operated, contracting air intlet mouth end recovers again air deflating state, if constantly Upwards channel material inlet is thrown cylindrical material, each cylindrical material, capital process: lose heart---the process of pressurization acceleration, and flexible flap, wear-resisting steel plate passes through in throwing cylindrical material process: loosen---the process of compression, thereby guaranteed that the formed air-flow of pressurized air air pressure flows to lower channel opening single direction.
Advantage of the present invention:
1, lower channel feed skewback, upper channel feed skewback right-hand member planar section a have been fixed and clamped side of flexible flap, while making its two sides at flexible flap all be barometric pressure, flexible flap is owing to being that elastic rubber material is made, because making flexible flap, elastic force is attached on upper channel feed skewback institute adhering and sealing pad, during throw over switch conversion, gas pressure can make flexible flap and bonding wear-resisting steel plate be pressed on the bonding sealing gasket of upper channel feed skewback rapidly, and pressurized air can not leak from upper channel material inlet;
2, the present position of connection of lower channel feed skewback, upper channel feed skewback, flexible flap, wear-resisting steel plate is on an inclined-plane, while carrying cylindrical material, cylindrical material is on the surface of the bonding wear-resisting steel plate of artificial throwing percussion flexible flap, owing to being so that inclined-plane resistance is little, and also little to wear-resisting steel plate wearing and tearing;
3, flexible flap bonding wear-resisting steel plate, increased compressive strength, reduced contact resistance, increased the sealing gasket tightness bonding with upper channel feed piece.
4, be to make up the perforating of opening a mine of current mine to open a mine and carry the domestic blank of stick dynamite machinery and the vacancy in market, provide a kind of mine borehole of increasing work efficiency to carry needed critical component in the semi-automatic conveyor mechanism of stick dynamite: a kind of flexible flap check valve.
