Abstract
The utility model relates to an automatic blowing plug valve which comprises a valve body, a valve cover and a piston integrated with a valve core. An air inlet cavity, an air outlet cavity, a piston cavity and a valve cavity are arranged in the valve body, a spring and a sealing blocking moving up and down are arranged in the air inlet cavity, an annular air storage cavity is arranged at the bottom of the piston, and an air channel is arranged in the valve body, so that plugging reverse blowing of a pneumatic conveying pipe is effectively achieved. Due to the fact that the integrated type valve body structure is adopted, the cost of a blowing plug device is greatly reduced.
Description
Technical field
The utility model relates to a kind of pipeline and automatically blows stifled valve, is specially adapted to the stifled valve that blows of delivery line in air-transport system.
Background technique
The material that generally all adopts pneumatic conveying mode to realize in cement plant, thermal power plant, chemical industry to produce more greatly and easily airborne dust as finished cement, pulverized fuel ash, agstone, silica flour equidensity from first to the transmission on second ground, one of mode of a kind of not only convenient but also clean environment firendly, but the obstruction that easily produces delivery line in course of conveying; For this reason, some strengths is carried manufacturer to adopt at pipeline and is arranged and manually blow stifled valve and carry out dredging pipeline, and both bothersome effort, again due to manual operation, unavoidable for causing man-made fault.Chinese patent ZL200420090075.5 discloses a kind of Pneumatic conveying pipeline anti-block device, by the automatic control of the combinations such as pressure transducer, PLC, solenoid valve, safety check is set, realize anti-blocking, this technology has solved the problem that delivery line stops up substantially, but component cost is higher.
Summary of the invention
The purpose of this utility model be design a kind of not only safe and reliable, but also cost-effectively automatically blow stifled valve.The technical solution of the utility model is so to realize:
A kind ofly automatically blow stifled valve, comprise valve body 1, valve gap 2, piston 4 with spool 5 one, valve body 1 inside arranges air-inlet cavity 12, outlet chamber 16, piston cavity 7, valve pocket 19, outlet chamber 16 is connected with conveyance conduit, described spool 5 front ends arrange valve rod 9, the mode that maintains gas between the outer wall of valve rod 9 and valve pocket 19 inwalls is made Spielpassung, described air-inlet cavity 12 arranges spring 11, the sealing block 10 moving up and down, the bottom of described piston 4 arranges annular air storing cavity 17, described valve body 1 inside arranges gas channels 14, the suction port 18 of described gas channels 14 communicates with air-inlet cavity 12, described gas channels 14 arranges Liang Ge air outlet, Yi Ge air outlet communicates with outlet chamber 16 by valve pocket 19, another air outlet communicates with annular air storing cavity 17 by the gas channels of valve gap 2, when delivery line is unobstructed, suction pressure adds spring force and is greater than conveyance conduit pressure, trace pressurized air from air-inlet cavity 12 through gas channels 14, outlet chamber 16 flows to conveyance conduit, when conveyance conduit has the tendency of obstruction, in the delivery line being connected with outlet chamber 16, discharge pressure will slowly increase, simultaneously, pressure in annular air storing cavity 17 also can increase gradually, when the pressure within delivery pipe internal pressure adds annular air storing cavity 17 is greater than suction pressure and adds spring force, will back down sealing block 10 with the piston 4 of spool 5 one, pressurized air directly enters outlet chamber 16 from air-inlet cavity and to conveyance conduit, blows stifled.
As preferably, on described gas channels 14, adjusting bolt 15 is set, for regulating the flow that enters gas channels 14.
As preferably, the top of described piston 4 arranges seal dissepiment 17, adopts the seal dissepiment of integrated design, can effectively prevent air earial drainage.
As preferably, described piston 4, spool 5 arrange respectively seal ring 6,8 with valve body 1 surface of contact, prevent that the dust in pipeline is penetrated into air storing cavity 17.
The utility model design a kind of blows stifled valve automatically, comprise valve body, valve gap, with the piston 4 of spool one, by air-inlet cavity, outlet chamber, piston cavity, valve pocket are set at valve inner, the sealing block that air-inlet cavity arranges spring, moves up and down, the top of piston arranges annular air storing cavity, and valve inner arranges gas channels, effectively solves the problem that Pneumatic conveying pipeline stops up blowback, the utility model, owing to adopting the valve body structure of integral type, greatly reduces the cost that blows block apparatus.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the technical solution of the utility model is described in further detail.
Embodiment: with reference to accompanying drawing, a kind ofly automatically blow stifled valve, comprise valve body 1, valve gap 2, piston 4 with spool 5 one, valve body 1 inside arranges air-inlet cavity 12, outlet chamber 16, piston cavity 7, valve pocket 19, described spool 5 front ends arrange valve rod 9, the mode that maintains gas between the outer wall of valve rod 9 and valve pocket 19 inwalls is made Spielpassung, described air-inlet cavity 12 arranges spring 11, the sealing block 10 moving up and down, the bottom of described piston 4 arranges annular air storing cavity 17, described valve body 1 inside arranges gas channels 14, the suction port 18 of described gas channels 14 communicates with air-inlet cavity 12, described gas channels 14 arranges Liang Ge air outlet, Yi Ge air outlet communicates with outlet chamber 16 by valve pocket 19, another air outlet communicates with annular air storing cavity 17 by the gas channels of valve gap 2, regulate for convenience the pressure of blowback, adjusting bolt 15 is set on gas channels 14, for Leakage prevention and dust enter air storing cavity, seal dissepiment 17 and seal ring 6 are set respectively, 8.
A kind of specific works method of automatically blowing stifled valve of the utility model, when normal, the trend of gas is that the female pipe of pressurized air 20 1 manual ball valves 21 1 blow the female pipe 24 of stifled valve one safety check 23 1 conveying automatically, when conveyance conduit is unobstructed, suction pressure adds spring force and is greater than conveyance conduit internal pressure, air from air-inlet cavity 12 through gas channels 14, outlet chamber 16 flows to conveyance conduit, when delivery line has the tendency of obstruction, in the delivery line being connected with outlet chamber 16, discharge pressure will slowly increase, simultaneously, pressure in annular air storing cavity 17 also can increase gradually, when the pressure within delivery pipe internal pressure adds annular air storing cavity 17 is greater than suction pressure and adds spring force, will back down sealing block 10 with the piston 4 of spool 5 one, pressurized air directly enters outlet chamber 16 from air-inlet cavity and to conveyance conduit, blows stifled.After conveyance conduit dredging, pressure drop in pipeline, when micro-, pressurized air flows to conveyance conduit by gas channels 14, outlet chamber 17 again, and air storing cavity 17 internal pressures on piston top decline, and spring 11 promotes sealing block 10 and closes the gas channel that blows to conveyance conduit.
