Description
Technical field
The present invention relates to a kind of refractory protection of ventilating duct for conveying high greasy dirt/high powder dust fluids, be applicable to the high greasy dirt of conveying of fire protection requirement, high powder dust fluids ventilation duct.Belong to the building fire protection facility technical field.
Background technique
At present, in building, adopt to divide this measure of fire zoning, in case can be when the building breaking out of fire, effectively the control of fire in certain scope, reduce fire loss, can put out a fire to save life and property for safety evacuation, fire-fighting simultaneously advantage is provided.Fire zoning, according to prevent that the function that fire expands can be divided into two types beyond fire zoning: the vertical fire zoning of the first, in order to prevent that vertical breaking out of fire spreads between multilayer or high-rise layer and the layer; It two is horizontal fire zonings, expands in the horizontal direction in order to prevent fire.Vertical fire zoning is meant with fire performance floor and wall between windows (containing breast) preferably, the fire resisting division of each floor being carried out in the Vertical direction of building.Horizontal fire zoning is meant the fire prevention division that each floor is separated out in the horizontal direction with fire resisting division things such as FW or fireproof door, fire resisting shutters.It can stop fire to spread in the substantially horizontal of floor.For ventilation duct passing fire wall or situation such as fireproof door, fire resisting shutter, existing technology normally is provided with a kind of fire resisting construction of blade type.When ventilation duct is when being used to carry high greasy dirt, high powder dust fluids; Because the blade of fire resisting construction places fluid, time one long oil is dirty, dust can cause this fire resisting construction malfunctioning attached on the blade easily; Cause fire-closing valve to close when serious, threaten building firesafety.And said blade type fire resisting construction fluid flow causes certain resistance, increases the conveying energy consumption of fluid, and long-time back greasy dirt, the dust of using can further increase resistance, increase conveying energy consumption attached on the blade.
Summary of the invention
The object of the invention; Be in carrying high greasy dirt, high powder dust fluids ventilation duct, to have the defective that conveying energy consumption is high, fire-proof function lost efficacy easily, a kind of refractory protection of ventilating duct for conveying high greasy dirt/high powder dust fluids is provided in order to overcome existing blade type refractory protection.
The object of the invention can reach through following technological scheme:
The refractory protection of ventilating duct for conveying high greasy dirt/high powder dust fluids; Its structural feature is: comprise collapsible blade mechanism, guide rail and be fixed on the extending means in the guide rail; The upper end of collapsible blade mechanism is fixedly connected with the top of guide rail, the lower end of collapsible blade mechanism is fixedly connected with the head of extending means; Collapsible blade mechanism comprises that several blades are formed by connecting; Be connected to form several intermediate active ends by head and the tail between the said blade, the tail end of extending means is fixedly connected with the bottom of guide rail; Be provided with a temp-sensitive apparatus in the extending means, the signal output part of this temp-sensitive apparatus is connected with the control input end of extending means.
Can constitute the curtain type fire-closing valve by collapsible blade mechanism, guide rail and the extending means that is fixed in the guide rail; When said fire-closing valve is in opening state; Its leaf folding is placed on the top of the fluid in the ventilation duct; Can fluid flow not cause resistance, greasy dirt, dust also are not easy attached on the blade simultaneously.When breaking out of fire, thalposis mechanism sees the control end that signal is given extending means off, and extending means drives folding blade and launches along guide rail; Launch fully ventilation duct is closed until blade, stop air to get into ventilation duct, thereby play the effect of fire-fighting fire-proof.
The curtain type fire-closing valve that the present invention constitutes not only can guarantee fire safety but also can save conveying energy consumption in carrying high greasy dirt, high powder dust fluids ventilation duct; Also can be applied in the common ventilation duct simultaneously.
The object of the invention can also reach through following technological scheme:
A kind of embodiment of the present invention is: the length of guide rail can be greater than the depth of section of pipeline, makes between the inwall of top and pipeline of guide rail and forms recess, and collapsible blade mechanism is hidden in this recess at folded state.
A kind of embodiment of the present invention is: can be provided with the aluminium foil thin slice near the recess place, an end of this aluminium foil thin slice is fixedly connected with tube wall, the other end is free end, and the blade of the size of this aluminium foil thin slice and shape and collapsible blade mechanism coincide.
A kind of embodiment of the present invention is: the intermediate active end that is formed by the blade tie point can be 1～20.
The invention has the beneficial effects as follows:
1, the present invention constitutes the curtain type fire-closing valve by collapsible blade mechanism, guide rail and the extending means that is fixed in the guide rail, and when pipeline was normally carried conveying high greasy dirt/high powder dust fluids, extending means drove the collapsible blade mechanism and folds up; The curtain type fire-closing valve is in opening state; Its leaf folding is placed in the recess of top of the fluid in the ventilation duct, does not contact with the fluid that is transferred, and neither can fluid flow cause resistance; Can not cause greasy dirt, dust etc. attached on the blade yet; The vane extension that makes the curtain type fire-closing valve is guaranteed when fire alarm takes place, can normally close freely, guarantees building firesafety.Simultaneously; Be provided with the blade isolation that the aluminium foil thin slice can make fluid and curtain type fire-closing valve near the recess place; Further prevent greasy dirt, dust etc. attached on the blade, when guaranteeing, can normally close, guarantee to add one deck insurance aspect the building firesafety in the generation fire alarm.
2, the present invention not only can guarantee fire safety but also can save conveying energy consumption in carrying high greasy dirt, high powder dust fluids ventilation duct; In common ventilation duct, also can promote the use of.
