Abstract
The utility model relates to a discharging and gas locking device capable of automatically compensating for abrasion of a sealed surface, which comprises a lower valve, an upper valve, a wedge sealing sleeve and a pot type inserting plate. The wedge sealing sleeve is mounted outside the upper valve, and a wedge surface is disposed at the bottom of the wedge sealing sleeve and contacts with the pot type inserting plate to realize sealing. The section of the pot type inserting plate is reversed-'L'-shaped, the ends of two sides of the reversed-'L'-shaped section of the pot type inserting pot are arc-shaped, a sealing structure of the pot type inserting plate with the wedge sealing sleeve adopts linear contact, and a linear contact portion of the pot type inserting plate is positioned above the plane of a discharge outlet of the upper valve. The discharging and gas locking device has the advantages that 1, the wedge sealing sleeve and the pot type inserting plate are adopted, the sealed contact surface is inclined and can be automatically compensated after abrasion, sealing performance is fine, and service life is long, 2, the wedge surface of the wedge sealing sleeve does not contact with materials so that the sealing performance is reliable, and 3, the wedge inserting plate is supported by a carrier roller and is flexible in movement. The discharging and gas locking device is widely applied to equipment, devices and systems such as dust removal equipment, dust falling devices and the like which have gas exhausting and locking requirements.
Description
Technical field
The utility model relates to a kind of discharge air-lock device of energy automatic compensation sealing surface wear, and being widely used in dusting equipment, dust falling device, Pneumatic conveyer etc. has discharge to lock on the unit of gas requirement or in the system.
Background technology
In the prior art, adopt Jameson scheme discharge valve, double-deck turnover plate type unloading valve, double-deck ball valve, double-deck push-pull valve etc. in dusting equipment, dust falling device, Pneumatic conveyer or the system, material is discharged from system, and do not allow gas enter system from the outside or intrasystem gas releases, the continuous work of system is gone down, but these sealed valve body structures all exist weak point.
Jameson scheme discharge valve, double-deck push-pull valve can not seal fully owing to exist the gap between movable parts of itself and the fixed parts;
The movable parts of ball valve own and the valve seat of double-deck ball valve have leakproofing material, and gas, liquid are had good sealing function, and service life is also very long, but for the granular solids material, because serious wear will soon lose sealing property, and the cost of ball valve is also very expensive;
Compare with valve body recited above, double-deck turnover panel unloading valve is used comparatively extensive, but it also exists important disadvantages, and the turnover panel serious wear can lose sealing property after use a period of time, device or system's cisco unity malfunction under causing.
Solution to the problems described above is in the prior art: one, change the parts that are worn; Its two, change leakproofing material; Its three, change valve integral body.No matter adopt above-mentioned which kind of method, all can cause stopping production.
Summary of the invention
The purpose of this utility model provides the discharge air-lock device that a kind of novel structure, sealing property are reliable, rubbed surface can be realized automatic compensation, long service life.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of discharge air-lock device of energy automatic compensation sealing surface wear, comprise valve body, upper valve body, wedge-type sealing shroud, alms bowl formula plate down, the wedge-type sealing shroud is installed in the upper valve body outside, and described wedge-type sealing shroud bottom is a wedge surface, and this wedge surface contacts with alms bowl formula plate realizes sealing.
The section shape of described alms bowl formula plate is
Shape,
The shape both side ends is circular-arc; Alms bowl formula plate is that line contacts with the hermetically-sealed construction of wedge-type sealing shroud, and this line contact site is positioned at more than the discharge gate plane of upper valve body.
Described alms bowl formula plate drives by cylinder or Electrohydraulic push rod, and alms bowl formula plate bottom is provided with carrying roller.
Compared with prior art, the utility model has the advantages that:
1) adopt wedge-type sealing shroud and alms bowl formula plate, sealing contact surface is the inclined-plane, but automatic compensation after the wearing and tearing, good seal performance, long service life;
2) wedge surface of wedge-type sealing shroud does not contact with material, and sealing property is reliable;
3) support the wedge-type plate by carrying roller, motion flexibly.

The specific embodiment
See Fig. 1, Fig. 2, a kind of discharge air-lock device of energy automatic compensation sealing surface wear, comprise valve body 1, upper valve body 2, wedge-type sealing shroud 3, alms bowl formula plate 4, cylinder or Electrohydraulic push rod 6, carrying roller 5, tie bolt 7 down, wedge-type sealing shroud 3 is installed in upper valve body 2 outsides, and wedge-type sealing shroud 3 bottoms are wedge surface.See Fig. 3-1, Fig. 3-2, Fig. 3-3, the front view section of alms bowl formula plate 4 is
Shape,
The shape both side ends is circular-arc; Alms bowl formula plate 4 is that line contacts with the hermetically-sealed construction of wedge-type sealing shroud 3, and this line contact site is positioned at more than the discharge gate plane of upper valve body 2, because sealing place does not contact good airproof performance and dependable performance with material; Because wedge-type sealing shroud 3 bottom surfaces are wedge surfaces, no matter are that the wearing and tearing or the wearing and tearing of plate of wedge-type sealing shroud can both compensate automatically by this wedge surface in the use, and can lose sealing function because of wearing and tearing.
Alms bowl formula plate 4 drives by cylinder or Electrohydraulic push rod 6, and alms bowl formula plate 4 bottoms are provided with carrying roller 5.Carrying roller 5 itself is rotatable parts flexibly, and alms bowl formula plate 4 is arranged on the carrying roller 5, and motion needs the application force of cylinder or Electrohydraulic push rod little, energy efficient flexibly.This device adopts unit construction formula structure, and parts have interchangeability.
Dusting equipment, dust falling device, air-transport system etc. have the discharge gate of the unit of exhaust lock gas requirement to link to each other with the inlet point 8 of discharge air-lock device, and inlet point 8 is positioned at upper valve body 2 tops.When the said equipment, device or system need discharge material, by cylinder or Electrohydraulic push rod 6 pulling alms bowl formula plates 4, make alms bowl formula plate 4 remove upper valve body 2, material is through upper valve body 2, the passage eliminating of valve body 1 formation down.In the use two discharge air-lock devices are installed in series together, the open and close that replaces is realized sealing discharging.
