Abstract
The invention belongs to the technical field of mechanical equipment, and relates to a self-locking pneumatic gate valve, in particular to a pneumatic gate valve used for an air conveying flume. The self-locking pneumatic gate valve is characterized by further comprising a lever mechanism provided with an extrusion block, insertion plates are symmetrically arranged at the upper end of a gate plate, and the insertion plates and the lever mechanism act mutually so that the extrusion block produces an extrusion force to the valve plate to avoid falling. The self-locking pneumatic gate valve has the advantages that the self-locking pneumatic gate valve is novel in concept and compact and reasonable in structure; the lever mechanism is adopted, an upward pushing force formed to the lever mechanism when the gate plate is opened is fully used, so that the extrusion block can extrude the gate plate effectively, the phenomenon that the valve plate is closed due to cylinder leakage is effectively avoided, loss caused by equipment overload is avoided, and the capital input to equipment loss is reduced.
Description
Technical field
The invention belongs to mechanical equipment technical field, particularly relate to a kind of Pneumatic gate valve for air conveyer flume.
Background technique
Pneumatic gate valve, as the important component part of air conveyer flume, is widely used in powder manufacturing enterprise, as cement plant, flour mill etc.Pneumatic gate valve comprises flashboard, support and cylinder, support is erected at above two adjacent air conveyer flumes, and cylinder is fixed on support, and the flexible rod lower end of cylinder connects flashboard, flashboard can stretch between two air conveyer flumes, plays partition two air conveyer flume.In actual using process, because site environment is severe, and expose to the weather, easily there is cracking gas leakage in the tracheae connecting cylinder, or directly ruptures, current check cannot find, once after start production, flashboard, under self gravitation effect, slowly falls until cut out, cause equipment interlocking to mediate, time serious, cause apparatus overload to damage.
Summary of the invention
In order to overcome the defect that prior art exists, the object of this invention is to provide a kind of self-locking pneumatic gate valve, structure is simple, practical, gate valve can be avoided to leak gas the closedown caused, effectively reduce the loss.
A kind of self-locking pneumatic gate valve, comprise flashboard, support and cylinder, support is erected at above two adjacent air conveyer flumes, and cylinder is fixed on support, and the flexible rod lower end of cylinder connects flashboard, flashboard can stretch between two air conveyer flumes, be characterized in the leverage also comprising band extrusion block, described flashboard upper end symmetry establishes plate, and plate and leverage interact, make extrusion block form extruding force to flashboard, avoid.
The present invention improves further, described leverage comprises a pair compression bar, a pair roller and a pair extrusion block, compression bar rotates and is fixed on support, and the head of compression bar is provided with roller, and afterbody is provided with extrusion block, when flashboard is not opened, two rollers are abutted against each other together, and when flashboard is opened, plate backs down two rollers, extrusion block is fitted in gate panel surface and forms extruding, avoids the flashboard caused because of cylinder leakage tester slowly to fall to closing under self gravitation effect.
The present invention improves further, and described plate is cusp-shaped, and outer surface is arc.
The present invention improves further, and described extrusion block is made up of rubber.
Compared with prior art, advantage is that this self-locking pneumatic gate valve is novel, and structure letter is gathered, rationally; Adopt leverage, make full use of when flashboard is opened and form a thrust upwards to leverage, thus make extrusion block effectively extrude flashboard, the flashboard effectively avoiding cylinder leakage tester to cause cuts out, the loss that the overload avoiding equipment causes, decreases the capital input of equipment loss.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is a kind of structural representation of self-locking pneumatic gate valve;
Fig. 2 is the side view of Fig. 1.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
As can be seen from Fig. 1,2, a kind of self-locking pneumatic gate valve, comprise the leverage 5 of flashboard 1, support 2, cylinder 3 and band extrusion block 5-3, support is erected at above two adjacent air conveyer flumes 4, and cylinder is fixed on support, the flexible rod lower end of cylinder connects flashboard, flashboard can stretch between two air conveyer flumes, and described flashboard upper end symmetry establishes plate 1-1, and plate and leverage interact, make extrusion block form extruding force to flashboard, avoid.
Described leverage 5 comprises a pair compression bar 5-1, a pair roller 5-2 and a pair extrusion block 5-3, compression bar rotates and is fixed on support 2, the head of compression bar is provided with roller, afterbody is provided with extrusion block, and when flashboard 1 is not opened, two rollers are abutted against each other together, when flashboard is opened, plate backs down two rollers, and extrusion block is fitted in gate panel surface and forms extruding, avoids the flashboard caused because of cylinder leakage tester slowly to fall to closing under self gravitation effect.
Preferred as the present embodiment, described plate 1-1 is cusp-shaped, and outer surface is arc.
Preferred as the present embodiment, described extrusion block 5-3 is made up of rubber.
