Abstract
The utility model discloses a self-aligning poppet valve, which comprises a valve plate and an air cylinder, wherein the on-off between the valve plate and a bin gate is realized through the air cylinder, the lower part of the air cylinder is provided with an air cylinder rod which is connected with a spherical connecting rod, and the spherical connecting rod is movably connected with the valve plate; and the bin gate is provided with a valve seat, and a contact surface between the valve seat and the valve plate is set to be a cone shape. In the utility model, the valve plate can be automatically aligned with the valve seat in a falling process, and the poppet valve has good sealing property and stable work.
Description
Affiliated technical field
The utility model relates to the poppet valve on a kind of sack cleaner door, particularly a kind of automatic alignment lift valve.
Background technique
At present, when the sack cleaner off-line ash-clearing, what be used for the door keying generally is to adopt the lifting type valve, offers a circular hole on the door of sack cleaner, and this circular hole is complementary with the valve plate of circle, promotes the upper and lower action of valve plate by cylinder again and realizes keying.This poppet valve makes usually good automatic capturing circular hole of valve plate owing to make, install the error that exists, and also the out-of-flatness owing to valve plate and deduster door is difficult to accomplish good sealing.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of automatic alignment lift valve is provided, but valve plate automatic capturing valve seat in dropping process, and good seal performance, working stability.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of automatic alignment lift valve, comprise valve plate, cylinder, described valve plate is by the keying of cylinder realization with door, described cylinder bottom is a cylinder column, described cylinder column is connected with a ball link, adopts between described ball link and the valve plate to flexibly connect; Be provided with a valve seat on described door, the surface of contact between described valve seat and the valve plate is set to taper.
As further improvement, described valve plate middle part upside is provided with a gland, is respectively equipped with the hemispherical groove that the ball with ball link is complementary in relative valve plate one side and gland one side, to realize the flexible connection between described ball link and the valve plate.
As further improvement, adopt connecting sleeve to be connected between described cylinder column and the ball link, described cylinder column bottom and ball link top are respectively equipped with one section outside thread, and described connecting sleeve two ends are respectively equipped with the internal thread that the outside thread with cylinder column bottom and ball link top is complementary.
As further improvement, adopt bolt to be connected between described gland and the valve plate, described gland is provided with some through holes, and described valve plate is provided with the hole that set through hole is complementary on some and the gland.
As further improvement, adopt bolt to be connected between described door and the valve seat, described valve seat outer ring is provided with some through holes, and described door is provided with the hole that set through hole is complementary on some and the valve seat outer ring.
The beneficial effects of the utility model are: between cylinder and valve plate, set up a ball link, and between ball link and the valve plate for flexibly connecting, make that promptly valve plate can universal within the specific limits rotation, but valve plate automatic capturing valve seat in dropping process; Valve seat and valve plate are designed to taper, and cone structure had both increased the surface of contact of valve plate and valve seat, also make valve plate tightly be pressed on the valve seat, realize good sealing property.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Fig. 2 is that A-A among Fig. 1 is to schematic representation;
Below in conjunction with accompanying drawing the utility model is described further:
Embodiment
As shown in Figure 1 and Figure 2, a kind of automatic alignment lift valve, comprise valve plate 2, cylinder 7, cylinder 7 bottoms are cylinder column 8, cylinder column 8 bottoms are provided with one section outside thread, and this cylinder column 8 is connected with ball link 3 by a connecting sleeve 4, also is provided with one section outside thread on ball link 3 tops, be respectively equipped with the internal thread that the outside thread with cylinder column 8 bottoms and ball link 3 tops is complementary at connecting sleeve 4 two ends, carry out socket with this; Adopt between this ball link 3 and the valve plate 2 and flexibly connect, promptly establish a gland 5 at valve plate 2 middle part upsides, be respectively equipped with the hemispherical groove that the ball with ball link 3 is complementary in relative valve plate 2 one sides and gland 5 one sides, to realize the flexible connection between ball link 3 and the valve plate 2; On gland 5, also be provided with four through holes, respectively with valve plate 2 on set four holes be complementary, and with bolt 6 fixing getting final product; On door, be provided with a valve seat 1, on valve seat 1 outer ring, be provided with eight through holes, respectively with door on set eight holes be complementary, and get final product, and the surface of contact between valve seat 1 and the valve plate 2 is set to taper with bolt, add large contact surface, good seal performance.
