Abstract
The present invention relates to a kind of pulse valve sealing device, described pulse valve includes valve body (1), gas bag (2), flap (3) and injection tube (6), described sealing device (4) is fixed in injection tube (6), described flap (3) is close on sealing device (4), during valve opening, moved on flap (3) position, the gas in gas bag (2) flows into injection tube (6) inside after being moved on flap (3) and sprays with the gap between sealing device (4).Compared with prior art, the present invention replaces original single injection tube hard sealing structure using the soft seal form of vulcanized rubber component, and increased inner seal slot, considerably increases the sealing property of pulse valve.
Description
Technical field
The present invention relates to the technical field of pulse valve, and in particular to a kind of pulse valve sealing device.
Background technology
Reinforcement with people to environmental protection consciousness, flue gas and treating flour dust receive extensive concern.Sack cleaner is got growing concern for its outstanding efficiency of dust collection, relatively low construction cost.And sack cleaner pulse valve is used as the important composition of sack cleaner, one of critical component as influence whole system cleaning efficiency.Therefore the various standards now for pulse valve and regulation are promulgated successively, the requirement more and more higher to manufacturer.But due to some objective factors, often there is the situation of valve gas leakage in existing pulse valve in use so that whole dust pelletizing system energy consumption increases.
The content of the invention
The purpose of the present invention is exactly the pulse valve sealing device that a kind of good seal performance is provided for the defect for overcoming above-mentioned prior art to exist.
The purpose of the present invention can be achieved through the following technical solutions：A kind of pulse valve sealing device, described pulse valve includes valve body, gas bag, flap and injection tube, described sealing device is fixed in injection tube, described flap is close on sealing device, during valve opening, moved in flap position, gap of the gas in gas bag after being moved on flap between sealing device flows into injection tube inside and spray.
Due to certain deformation can be produced after rubber stress, even if so that flap has certain deflection to nor affect on its sealing property in laminating.
Described sealing device includes vulcanised rubber layer and skeleton, and described skeleton upper face covers the vulcanised rubber layer, and bottom is connected by screw thread with injection tube.
Described skeleton top is provided with saw-tooth grooves, and described vulcanised rubber layer interior wall construction matches with the saw-tooth grooves.
An O-ring seal is provided between described skeleton and injection tube.
The upper end of described skeletal internal screw thread is provided with escape, described O-ring seal is arranged in the escape, when described injection tube is screwed with described skeleton, O-ring seal just fills up the gap of escape and injection tube, inner sealing is realized, while special size plays a part of fixed and is oriented to injection tube again.
Described injection tube head is provided with chamfering, when described injection tube is screwed with described skeleton, chamfering import skeleton necking at, and with O-ring seal crush seal, while prevent clash into produce radial wobble.
Compared with prior art, beneficial effects of the present invention are embodied in following several respects：
(1) original single injection tube hard sealing structure is replaced using the soft seal form of vulcanized rubber component so that either which kind of seal form can be smooth is close on sealing surface for the flap of pulse valve.
(2) inner seal slot is increased, the leakage between sealing device and injection tube is prevented.
(3) one layer of vulcanised rubber layer is covered with the top of sealing device, due to certain deformation can be produced after rubber stress, even if so that flap has certain deflection to nor affect on its sealing property in laminating.
(4) a few gang saw tooth-like recesses are devised above the skeleton of sealing device, the laminating intensity of skeleton and vulcanised rubber layer is met, while jagged structure increased the impact resistance of skeleton.
(5) sealing device is connected by screw thread and injection tube, there is escape in skeletal internal, an O-ring seal can be installed, when injection tube and sealing device are screwed, O-ring seal just fills up the gap of escape and injection tube due to extruding, reaches inner sealing effect.
(6) injection tube head chamfering just imports skeleton inner radius after sealing device is screwed, and prevents from clashing into the radial wobble for producing.
