Abstract
The utility model relates to a pneumatic conveying bell cover valve, which comprises an air cylinder, wherein a piston rod of the air cylinder is hinged with one end of a shaft handle connecting rod mechanism, the other end of the shaft handle connecting rod mechanism is hinged with a guide rod, the guide rod is connected with a bell cover arranged in a valve body through a double-threaded connecting rod, the top end of the valve body is provided with a flange connected with a feeding device, a flange is arranged at the bottom end of the valve body, a rubber ring is arranged in the flange, and the bell cover is sealed with the valve body through the rubber ring. The pneumatic conveying bell cover valve adopts a hemispherical bell cover valve, the vertical movement is adopted in the action process, the friction with the sealing ring is not needed, the contact area between the hemispherical bell cover valve and the sealing ring is increased, the sealing performance is improved, the forms of feeding openings are diversified, and the production efficiency is effectively improved.
Description
Technical field
The utility model relates to the belljar valve field, relates in particular to the pneumatic conveying belljar valve that a kind of strength is carried usefulness.
Background technology
In the process of carrying concentrated phase powdery material, the domestic strength of generally using is carried and is sent jar, adopts Pneumatic butterfly valve or ball valve, and this structure needs dish plate or spheroid to rotate when opening, and has following shortcoming:
(1) dish plate or spheroid contact with O-ring seal, and after the long-term work, dish plate or spheroid and O-ring seal produce friction; Friction is heated and is caused the rubber ring distortion; The most easy to wear to the big material of chiseling property of mill especially, the wearing and tearing back can't be used with regard to producing gas leakage, influences leak tightness.
(2) the inlet point form is single, has reduced production efficiency.
The utility model content
The applicant provides a kind of pneumatic conveying belljar valve to the shortcoming in the above-mentioned existing structure, and it can improve leak tightness and production efficiency.
The technical scheme that the utility model adopted is following:
A kind of pneumatic conveying belljar valve comprises cylinder, and an end of the piston rod of cylinder and footstalk connecting rod mechanism is hinged, and the other end and the pilot bar of footstalk connecting rod mechanism are hinged, and pilot bar is connected with bell jar in being arranged at valve body through two threaded rod; The top of valve body is equipped with the flange that is connected with feed arrangement, and the bottom of valve body is equipped with flange, and rubber ring is installed in the flange, and bell jar and valve body are through seal with elastometic washer.
It is further characterized in that:
Said feed arrangement is two logical inlet point or threeway inlet points;
Said bell jar is a semisphere.
The beneficial effect of the utility model is following:
The utility model adopts the semisphere belljar valve, and compared with prior art, course of action is a perpendicular movement, need not and the seal ring friction, and the area of contact of semisphere belljar valve and seal ring increases, and has improved sealing property; Two logical inlet point or threeway inlet points are adopted in the diversification of inlet point form, effectively raise production efficiency.
Description of drawings
Fig. 1 is the cross-sectional schematic of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described.
As shown in Figure 1, the piston rod of cylinder 1 and footstalk connecting rod mechanism 2 are hinged, are used to drive opening and closing of hemisphere bell jar 5, and footstalk connecting rod mechanism 2 is hinged with pilot bar 8, in pilot bar 8, has threaded mounting hole.Be welded to connect contiguous block 11 at the center of hemisphere bell jar; Also have threaded mounting hole in the contiguous block 11; Through two threaded rod 9 and contiguous block 11 pilot bar 8 is connected with hemisphere bell jar 5, hemisphere bell jar 5 is a spherical arc with the sealing surface of valve body 3, and through rubber ring 4 sealings.Because the area of contact of hemisphere bell jar and rubber ring 4 increases, and has improved leak tightness.Rubber ring 4 adopts the heat-resisting material of antifriction to make, good springiness, and it continues that hardness about 65 degree.The flange 7 that is connected with inlet point is installed on the top of valve body 3, and the bottom of valve body is equipped with the flange 10 that is connected with discharging opening.Flange 7 bonded assembly feed arrangements are two logical inlet point or threeway inlet points, are connected to two logical inlet points among Fig. 1.
The working process of the described belljar valve of the utility model does, when cylinder 1 work, footstalk connecting rod mechanism 2 drives the pilot bars 8 coupled semisphere bell jars 5 that connect and transfers, and belljar valve is opened.When carrying on the pilot bar 3 drive bell jars 5, belljar valve is closed.
The content of not doing in this specification sheets to describe in detail belongs to this area professional and technical personnel's known prior art.
More than describing is the explanation to the utility model, is not the qualification to utility model, and the utility model institute restricted portion is referring to claim, and under the situation of the basic structure of the utility model, the utility model can be done any type of modification.
