Background technology
Powder body material pneumatic conveying system, at present at electric power, building materials, metallurgy, food, fields such as pharmacy have obtained using widely.The strength conveying itself belongs to a later-model field, along with the many components and parts of continuous development of strength conveying practical application and the problem of critical parts also day by day manifest, wherein the most representative problem is a bleeder valve, and it is characterized by: the life-span is short, poor sealing performance, it is serious to leak.Be for user's reflection directly perceived: valve is changed frequent, work under bad environment, concerning valve manufacturer: carry owing to belong to the gas-solid two-phase, valve technical risk than traditional infusion or gas transmission increases, and especially particulate matter shortens significantly to washing away with the valve opening and closing life of valve that causes not in place of position of sealing.
Summary of the invention
Order of the present utility model is exactly will overcome above-mentioned deficiency and a kind of valve body that provides and the sealing between the valve plate are to realize sealing by on the valve body up and down a wear-resistant seal circle being set respectively, a scavenging conduit respectively is set before and after valve body realizes that valve plate opens and closes and put in place.
The solution that realizes the utility model purpose is a kind of pneumatic dry ash bleeder valve, comprise upper valve body (1), following valve body (2), valve plate (3), cylinder (18), particularly respectively have a circular groove (4) on the valve body (2) down at upper valve body (1), be provided with wear-resistant seal circle (5) in the circular groove (4), valve plate (3) is installed between upper valve body (1) and the following valve body (2), have cavity (22) in the rear portion of valve body (2) down at upper valve body (1), the front portion has cavity (24), the front and rear part cavity is communicated with by passage (25), upper valve body (1) forms a complete cavity in the involutory back of valve body (2) down, in the front and back of valve body a scavenging conduit (10) is set respectively, (11), scavenging conduit (10), (11) link to each other with machine control valve (13) by check valve (21), machine control valve (13) links to each other with compressed air source.
The cross-sectional plane of circular groove (4) is circle, triangle, polygon.Wear-resistant seal circle (5) seals valve plate (3) both sides.
The utility model has the advantages that sealing is reliable, valve plate opens and closes and puts in place, and working accuracy is low, and assembly and adjustment is convenient, greatly reduces manufacturing cost, has improved service life.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Upper valve body (1) valve body (2) down fixedly is made up of by bolt (6) two the same valve halfbodies of profile, upper valve body (1) rear portion of valve body (2) is down connected by bolt (8) pull bar (9) by seal receptacle (7), a purging tracheae (10), (11) respectively are set the front and back of valve body (2) down at upper valve body (1), scavenging conduit (10), (11) link to each other with machine control valve (13) by check valve (21), and machine control valve (13) links to each other with compressed air source.Between the same valve halfbody of two profiles, valve plate (3) is housed, valve body (2) is gone up the one side by valve plate (3) under upper valve body (1), concentric with the through hole (23) of valve body (2) under the upper valve body (1), have circular groove (4), be provided with wear-resistant seal circle (5) in the circular groove (4), upper valve body (1) forms rear cavity (22) in the involutory back of valve body (2) seal receptacle (7) down, front cavity (24), the front and rear part cavity is communicated with by passage (25), purge tracheae (10), (11) be communicated with valve pocket, scavenging conduit (10), (11) other end links to each other with machine control valve (13) by check valve (21), and machine control valve (13) links to each other with compressed air source.Cylinder (18) and valve rod (15) are by being threaded, and valve rod (15) links to each other by bearing pin (14) with valve plate (3), loads packing (12) between seal receptacle (7) and valve rod (15).
During work, under the effect of cylinder (18), valve plate (3) slides between the valve body (2) down at upper valve body (1), and is closed or open through hole (23).When valve plate (3) was closed, machine control valve (13) cut off and purges pressurized air, and when valve plate (3) when opening, machine control valve (13) is connected and purged pressurized air, and pressurized air purges valve pocket by check valve (21) and scavenging conduit (10), (11); When valve plate (3) when opening, shelves iron (16) are stirred the signal that travel switch (19) provides valve to open to control cabin, when valve plate (3) is closed, shelves iron (16) are stirred travel switch (20) provides valve closed signal to control cabin, so that operating personal is in time understood operating condition.The gas that enters from purging tracheae (10), (11) is opened the back at valve plate (3) valve pocket is purged, and guarantees that valve plate (3) keying puts in place.Shelves iron (16) contact with machine control valve (13) when valve plate (3) is opened, and pressurized air purges by scavenging conduit (10), (11), when valve plate (3) when closing shelves iron (16) disengage with machine control valve (13), pressurized air stops to purge.Purge with its function of pressurized air only import but no export and realize by check valve (21).
Valve plate (3) when closing also available hand replace shelves iron (16) contact with machine control valve (13), pressurized air is by scavenging conduit (10), (11) dispatch from the factory pressure test and the judgement of use field failure.
The utility model also can be used for solid-liquid two-phase mass transport, only needs that the pressurized air in purging tracheae (10), (11) is changed to the band press liquid and gets final product.
Enforcement of the present utility model is not limited only to the form that accompanying drawing provides, with its similar form all be the scope of the utility model protection.
