Abstract
The utility model discloses a manual louver valve which comprises a flange, a shell body, a rotating shaft, a hollow shaft, blades, high-temperature abrasion-resistance rubber, a crank, a connecting rod and a handle. The flange is connected with the shell body. The rotating shaft is arranged in the shell body. The blades are fixedly connected with the hollow shaft. The rotating shaft is sleeved in the hollow shaft, and the rotating shaft is connected with the hollow shaft through bolts. The high-temperature abrasion-resistance rubber is arranged on edges of the blades and is connected with the blades through layering bolts. The handle is connected to the outside of the shell body and is connected with the shaft through the crank and the connecting rod. The manual louver valve can effectively control blowing rates in various severe environments, effectively ensures sealing performance due to the high-temperature abrasion-resistance rubber, can better control the leakage rate of valves and enables the leakage rate to be minimized, thus, waste gas can be better recycled in waste heat power generation.
Description
Technical field
The utility model relates to a kind of valve, is 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 purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of louver valve of controlling air quantity to be provided, by high-temperature wearable rubber is housed at blade edge, reaching air leak rate of air curtain less than 0.1%.And axle employing split-type structural, be easy to change blade.
The technical solution adopted in the utility model 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 utility model 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 utility model 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 utility model;
Fig. 2 is the side view of Fig. 1.
Embodiment
The utility model is described in further detail 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 utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.In the present embodiment not clear and definite each constituent element all available prior art realized.
