Abstract
The invention discloses a manually-operated louver valve, which comprises a flange, a casing, rotation shafts, hollow shafts, blades, a high temperature wear resistant rubber, cranks, a connecting rod, and handles, wherein the flange is connected with the casing; the rotation shafts are placed in the casing; the blades are fixedly connected with the hollow shafts; the rotation shafts are sleeved with the hollow shafts, and the two are in bolted connection; the high temperature wear resistant rubber is mounted at edges of the blades and the two are in bolted connection; the handles are connected with the external of the casing, and are connected with the rotation shafts through the cranks and the connecting rod. The valve can effectively control the blowing rate in various severe environments, effectively guarantees the sealing property particularly through the high temperature wear resistant rubber, can better control the leakage rate of the valve to a smallest level, and can allow exhaust gases to be better recycled and reused in a cogeneration.
Description
Technical field
The present invention relates to a kind of valve, be specifically related to a kind of manual louver valve.
Background technique
Manually, electric louver valve, through for a long time development, be widely used in cement, metallurgy, mine etc., when its appearance has solved each pipe ventilated well, need open and close and the effectively effect of control air quantity.
With regard to louver valve, it is mainly used in pipeline at present, can well control air quantity by louver valve, but aspect details or defectiveness, so the improvements of needs are still arranged.
Summary of the invention
The objective of the invention is provides a kind of louver valve of controlling air quantity in order to overcome the deficiencies in the prior art, by high-temperature wearable rubber is housed at blade edge, reaches air leak rate of air curtain less than 0.1%.And axle employing split-type structural, be easy to change blade.
The technical solution used in the present invention is: a kind of manual louver valve, comprise flange, housing, running shaft, hollow shaft, blade, high-temperature wearable rubber, crank, connecting rod and handle, described flange is connected with housing, in housing, lay running shaft, blade is fixedly connected with hollow shaft, and running shaft is inserted in hollow shaft and utilizes bolt to connect, and at blade edge high-temperature wearable rubber is housed and utilizes the press strip bolt to connect, handle is connected to outside, and is connected with axle with connecting rod by crank.
When louver valve was closed, rubber can be fine, be attached on the blade of lower one page very compactly, is lower than 0.1% thereby air leak rate of air curtain is controlled at.
The present invention can pass through the adjusting louver plate, utilizes the high-temperature wearable rubber at shutter board edge, be attached to compactly on the shutter board of lower one page, thus the air leak rate of air curtain of reduction electric louver valve.
Beneficial effect: the present invention can be under various rugged environment, effectively control air quantity, the particularly appearance of this high-temperature wearable rubber, effectively guaranteed sealability, the leak-down rate of control valve better, its leak-down rate is minimized, like this in cogeneration, can allow the better recycling of waste gas.
Description of drawings
Fig. 1 is the structural representation of the manual louver valve of the present invention;
Fig. 2 is the side view of Fig. 1.
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments:
As illustrated in fig. 1 and 2, a kind of manual louver valve, comprise orchid 1, housing 2, running shaft 3, hollow shaft 4, blade 5, high-temperature wearable rubber 6, press strip 7, crank 8, connecting rod 9 and handle 10, described flange 1 is connected with housing 2, in housing 2, lay running shaft 3, blade 5 is fixedly connected with hollow shaft 4, running shaft 3 is inserted in hollow shaft 4 bolts and connects, at blade 5 edges high-temperature wearable rubber 6 is housed, press strip 7 is pressed in bolt connection housing 1 on the rubber 6, handle 10 is connected to housing 2 outsides, and is connected with connecting rod and is connected with running shaft 3 by crank 8.
Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.In the present embodiment not clear and definite each constituent element all available prior art realized.
