Abstract
The utility model discloses a warm-keeping ventilator for grain warehouse comprising a ventilating duct (1), an end cover (3) and a seal rubber ring (2) provided in the seal part between the ventilating duct (1) and the end cover (3), which is characterized in that a screw nut disposed in the internal side of the end cover (3) is engaged with a screw rod fixed on a bracket (8). The advantage is that the screw rod and nut compact the end cover to the seal surface of the ventilating duct to ensure a reliable air-tightness when the ventilator is closed. In addition, the screw rod, screw nut and the seal ring are all sealed inside the ventilating duct and isolated from the outdoor air, thereby, rustiness, erosion and rubber ageing caused by the temperature and humidity alteration are avoided.
Description
Technical field
The utility model belongs to grain storing technology field, the particularly ventilating opening in grain storage storehouse,
Background technology
The ventilating opening, particularly northern area in present grain storage storehouse have exchanged cold air when winter, have made it to reach after the temperature in the silo, need close; Perhaps, in stifling, also need tight sealing, excessive to prevent virulent gas.And this sealing, now flanged connections of adopting between ventilating opening end caps and the ventilating opening more, connect the surface and add a rubber matting, with one group of bolt that it is fastening, because the particularity of grain storage, after the general sealing of this ventilating opening, almost need year just can open, during this, owing to passed through temperature, the humidity in the four seasons, the rainwater in summer, and reason such as irradiation of sunlight, make screw thread corrosion, ageing of rubber, and cause the seal failure of ventilating opening section, next time often can't smooth opening when need open.
Summary of the invention
For overcoming the problem of above-mentioned existence, goal of the invention of the present utility model has been proposed.The technical solution of the present utility model purpose is in order to provide a kind of sealing reliable, to close and open convenient and reliable grain storage storehouse insulation ventilating opening device.
Goal of the invention of the present utility model is to realize according to following structure.This kind grain storage storehouse insulation ventilating opening device, comprise ventilating duct [1], end cap [3], end cap [3] has O-ring seal [2] with sealing place that is connected between the ventilating duct [1], and it is characterized in that the screw mandrel [7] on the inside portion of end cap [3] has a screw [6] and is fixed on screw mandrel support [8] cooperates.
The beneficial effects of the utility model be the screw mandrel screw with end cap by on the sealing ring sealing surface that is pressed in ventilating duct tightly, guarantee that the air-tightness after ventilating opening is closed is reliable.And, screw mandrel and screw are all in the inside of ventilating opening pipeline, sealing ring is also in the inside of the ventilating duct that has been closed, do not contact, thereby avoided temperature and humidity throughout the year to change the generation that brings the problems such as connection inefficacy that cause such as get rusty, burn into ageing of rubber etc. with outdoor air.
Description of drawings
Accompanying drawing 1 is a topology view of the present utility model.Sequence number in the accompanying drawing is: 1, ventilating duct, 2, O-ring seal, 3, end cap, 4, handgrip, 5, stifling pipe, 6, screw, 7, screw mandrel, 8, the screw mandrel frame, 9, wall.
The specific embodiment
With reference to accompanying drawing, grain storage of the present utility model storehouse insulation ventilating opening device, comprise ventilating duct [1], end cap [3], end cap [3] has O-ring seal [2] with sealing place that is connected between the ventilating duct [1], and it is characterized in that the screw mandrel [7] on the inside portion of end cap [3] has a screw [6] and is fixed on screw mandrel support [8] cooperates.What here need to illustrate a bit is that the position of screw and screw mandrel can exchange, and does not influence use.The periphery that handgrip [4] can be located at end cap also can be located on the lateral surface of end cap.Ventilating duct [1] generally all is placed in the position on the close ground of wall [9], installs with other operations all more convenient.O-ring seal [2] can adopt the solid hollow elastomeric material that also can adopt to make, or also can with the plastic material making.
