Abstract
The invention provides a high-temperature-resistant air duct valve which is good in airtightness and high in safety in a high temperature environment. The high-temperature-resistant air duct valve aims at overcoming the defects that blades of existing air duct valves are prone to getting stuck at the high temperature, so that the existing air duct valves cannot run normally and is ingenious in structure and capable of being better adapted to the high temperature. The high-temperature-resistant air duct valve comprises a valve body, blades, blade shafts, an execution mechanism, a temperature sensor and a connecting rod, wherein the execution mechanism controls the blades to be opened and closed; the temperature sensor is fixed to the valve body; fixing bases are arranged on the inner wall of the valve body, a movable groove is formed in the outer side of each fixing base, a spring is arranged between each movable groove and the corresponding fixing base, and when being stressed, each movable groove can compress the corresponding spring; each end of each blade shaft passes through the corresponding movable groove and is fixed into the corresponding fixing base, each blade is installed on the corresponding blade shaft in a sleeving mode, the ends of each blade are in contact with the corresponding movable grooves, and the blades are driven to rotate by the blade shafts. Compared with existing air duct valves, the air duct valve has the advantages of being good in airtightness and safe to use at the high temperature.
Description
Technical field
The present invention relates to the high temperature resistant airduct valve that good airproof performance in airduct valve technology field, particularly a kind of hot environment, Security are high.
Background technique
Airduct valve generally uses in modern architecture, is arranged on ventilation, the sending of air-conditioning system, air return pipeline in a large number, at ordinary times in opening state, runs into when maintenance or fire cause ambient temperature abnormal and can close, block air circulation, play the effect every cigarette back-fire relief.Along with the emphasis of security against fire consciousness, to the performance under fire-closing valve hot environment, especially the requirement of inleakage rises to critical positions.Fire-closing valve is in the market in order to improve sealing, and blade end and valve interior wall are fitted and do not stayed gap; When temperature rises to 1000 DEG C, the material expansion that temperature variation causes causes leaf blade expansion, because not having the spatial margin stretched, causes blade stuck, cannot normal operation, and when breaking out of fire, blade is stuck cannot closed amputation air stream, cannot play fire-fighting effect.
Summary of the invention
The object of the invention is for easily there is blade under existing airduct valve high temperature stuck and cannot the deficiency of normal operation, the high temperature resistant airduct valve that a kind of structure is ingenious, better can adapt to high temperature is provided.
The present invention completes in the following way: a kind of high temperature resistant airduct valve, and this is high temperature resistant, and airduct valve comprises valve body, blade, sharf, actuator, temperature transducer and connecting rod, and wherein, the unlatching of blade passes through actuating mechanism controls with closed; Temperature transducer is fixed on valve body; The inwall of valve body is provided with fixed base, and the outside of fixed base is provided with loose slot, is provided with spring between loose slot and fixed base, the stressed compressible spring of loose slot; The end of sharf is passed loose slot and is fixed in fixed base, and blade is sleeved on sharf, and the end of blade contacts with loose slot, and blade rotates under the drive of sharf; The Compressive activities groove when leaf blade expansion, the stressed movement of loose slot, spring contraction; When vanes retract, loose slot moves under the restoring force effect of spring, guarantees the sealing between blade and loose slot, also ensure that blade can normal rotation.
In described high temperature resistant airduct valve, the middle part of described fixed base is provided with projection, and protruding in trapezium structure, protruding middle part is provided with bearing, and end and the bearing of sharf interfix.
In described high temperature resistant airduct valve, described loose slot is the groove shapes of opening, large compared with the length on short base than fixed base projection of the opening length of loose slot, little compared with the length on long base than fixed base projection, the opening end of loose slot matches with the projection of fixed base, during leaf blade expansion Compressive activities groove, loose slot generation deformation; When extruding force reduces or disappear, loose slot restores to the original state under natural resiliency effect.
In described high temperature resistant airduct valve, the side that described loose slot contacts with blade is arch, increases the deformability of loose slot.
In described high temperature resistant airduct valve, the both sides inwall of described valve body is equipped with loose slot, matches with loose slot respectively in the two ends of blade.
Be provided with loose slot and spring structure in the present invention is high temperature resistant airduct valve, effectively adapt to the needs that expand with heat and contract with cold of room temperature and high-temperature condition lower blade.When causing blade to expand with heat and contract with cold when environment temperature change, loose slot Compress Spring makes blade have the space of expansion, guarantees the sealing of airduct valve, avoid leaf blade expansion and cause that blade is stuck cannot the situation of normal operation; When blade shrinkage, loose slot moves under the action of the spring, guarantees the sealing between blade and loose slot.The present invention at high temperature has good sealing, and inleakage meets fire-fighting demand completely, increases safety in utilization.
The present invention, compared with existing airduct valve, has that high temperature seal performance is good, the feature of use safety.
