Summary of the invention
The purpose of this utility model provides a kind of low noise safety type high seal double layer dump valve, with easy buildup, the seal ring technical problems such as the sealing effect that causes is poor, the working environment noise is large such as easily come off in the surface that solves the up and down unloading valve that traditional Double-deck cinder discharge valve exists.
The utility model is realized the foregoing invention purpose, and the technological scheme that adopts is as follows:
A kind of low noise safety type high seal double layer dump valve comprises seal case, lower seal casing, up and down unloading valve, gray moving dish and drive unit; Described drive unit is respectively to up and down unloading valve driving, its structure comprises respectively in the swing arm that is connected by ball-joint with unloading valve up and down, rotating shaft that the described swing arm the other end connects respectively, the rotating shaft fixing respectively followup cam and counter weight device, swing arm, followup cam and counter weight device that described up and down unloading valve connects rotate respectively synchronously, and two followup cams that described up and down unloading valve connects are swung by a rotary actuation actuated by cams; Described upper unloading valve is positioned at the feeding funnel infraoral of seal case, and upper unloading valve and feeding funnel infraoral are the sealing surface design of non-level inclined-plane, and the gray moving dish is positioned at the unloading valve upper-end surface; Lower unloading valve is positioned at the upper oral part of lower seal casing.
Upper unloading valve and feeding funnel infraoral are the angle of inclination of upper unloading valve of non-level inclined-plane sealing surface greater than the stocking angle of material.
Between the sealing surface of feeding funnel lower sealing surface, lower unloading valve and the lower seal casing of upper unloading valve and corresponding upper seal case, respectively is furnished with respectively one group of high-temperature resistant seal ring, wherein one group be the plane sealing face with corresponding sealing surface on blade-like flange collar fitted seal, another group is the plane sealing face fitted seal on blade-like flange collar and the corresponding sealing surface.
Advantage of the present utility model is as follows: unloads in the grey process whole, and unloading valve slowly closing under the control of safety drive and counterweight up and down, noise is extremely low; Upper unloading valve adopts inclined design, and when unloading valve was closed in the assurance, the surface is dust stratification not; Adopt the structure of the inserted double-sealing of blade, improved sealing effect.The utility model Safety performance is good, sealing effect is strong, noise is low, it is smooth and easy to unload ash.The employing spheroid is hinged, and unloading valve swings arbitrarily centered by the strut spheroid within the specific limits up and down, and the energy self-aligning can be offset in making, install, using for a long time and is out of shape the error that causes.
Description of drawings
Fig. 1 is structure sectional view of the present utility model.
Fig. 2 is the structure sectional view of sealing surface of the present utility model.
Embodiment
The utility model comprises seal case, lower seal casing, up and down unloading valve, gray moving dish, drive unit, pumping arm action, cam etc.Unloading valve connects by ball-joint respectively with the swing arm of being connected up and down, is fixed by gland.The rotating shaft of swing arm end is by the actuated by cams on the motor, swing arm rotation and open unloading valve.The gray moving dish is arranged on the ash discharge valve, drive the gray moving disc spins during unloading valve Unscrew, thereby destroy the stability of ash, ash smoothly falls.Finish Deng unloading ash, upper unloading valve is under the effect of counterweight in the swing arm, along the cam specific curves and the counterrotating slowly closing.Then with above-mentioned process, lower unloading valve unloads ash and processes.Guarantee like this to unload in the grey process, the upper strata unloading valve is airtight all the time, does not leak out.
The sealing surface of unloading valve and seal case respectively is furnished with one group of high-temperature resistant seal ring up and down.And there is the flange collar of an outstanding blade-like at the sealing surface edge of seal case.The seal ring of unloading valve all is embedded in inside up and down, flushes with sealing surfaces one, prevents solid accumulation.When up and down unloading valve was closed, the blade-like flange collar on the seal case can be pressed on the seal ring, and flange collar is mounted to up and down in the unloading valve.Seal ring is squeezed in groove, and not only good sealing effect, and seal ring is difficult drop-off also.
Below in conjunction with accompanying drawing, enforcement of the present utility model is described further.
Low noise safety type high seal double layer dump valve, it comprises seal case (7), lower seal casing (9), upper unloading valve (3), lower unloading valve (8), gray moving dish (1), drive unit (10), swing arm (4), cam (5), counterweight (6), spheroid (2), followup cam (11), rotating shaft (12) etc.
When Double-deck cinder discharge valve is worked, cam (5) on the drive unit (10) is along with the motor rotation, drive followup cam (11) drive rotating shaft (12) and swing arm (4) along with the rotation of cam (5) with upper unloading valve (3) Unscrew, be discharged to upper seal case (7) fully when interior Deng ash, upper unloading valve (3) under counterweight (6) effect along the curve of cam (5), slowly closing.Then descend unloading valve (8) the same with upper unloading valve (3), be opened equally, ash is drawn off, then close.Unload in the grey process whole, unloading valve (3), (8) all are slowly closings up and down, and noise is extremely low.Double-deck cinder discharge valve guarantees that unloading valve has one to be in closed condition all the time up and down in whole working procedure.
Because up and down unloading valve (3), (8) and swing arm (4) are ball-joints, have self-aligning function, therefore when about unloading valve (3), (8) when closing, can adapt to the seal case sealing surface fully, fit tightly.Swing arm (4) and counterweight (6) are fixed in the rotating shaft (12) simultaneously, simultaneously rotation centered by rotating shaft.
Upper unloading valve is when closing, owing to constantly having ash to fall in the large flue, the above unloading valve of institute (3) is in closing process, because sealing surface adopts ramp structure, the angle of inclination of upper unloading valve (3) is greater than the stocking angle of material, so just can dust stratification on the sealing surface.Sealing surface and seal ring can be adjacent to closely, do not leak out.
As shown in Figure 2, the sealing surface among of unloading valve (3), (8) and upper-lower seal casing (7), (9) is furnished with two cover high-temperature resistant seal rings (14), (15) up and down.There is the flange collar of an outstanding blade-like at high-temperature seal ring (15) edge of the sealing surface of upper-lower seal casing (7), (9).The seal ring (14) of unloading valve (3), (8) all is embedded in inside up and down, flushes with sealing surfaces one, namely prevents solid accumulation, again can wear prevention.When unloading valve (3) up and down, when (8) are in and close, the cutter head shape flange collar of the high-temperature seal ring (15) on upper-lower seal casing (7), (9) can be pressed on the sealing surface of up and down unloading valve (3), (8).The seal ring in groove (14) of unloading valve (3), (8) is pushed by the blade-like flange collar (13) on upper-lower seal casing (7), (9) up and down, and not only good sealing effect, and seal ring is difficult drop-off also.
