Description
(1) technical field
This utility model relates to a kind of valve, specifically a kind of adjustable water conservancy diversion fireproof check valve for flue.
(2) background technology
Flute check valve is also called reflux valve, non-return valve, counterbalance valve, check valve, it is mounted in a kind of valve preventing oil smoke taint of odour on common flue, this kind of valve is the power that produces of the flowing of tube road medium itself and opens and closes automatically, and belongs to a kind of automatic valve.For monoblock type hardware, adopt metal material, be provided simultaneously with fire prevention, it is prevented that flue gas pours in down a chimney and the function of air-out wind-guiding upwards.Requirement according to Minstry of Housing and Urban-Rural Development of People Republic of China (MOHURD) and Environmental Protection Administration, must install central exhaust road fire-preventing check valve before house is delivered for use, and reduces and pollutes, and meanwhile, this is also the symbol of human civilization progress.
Check-valves is used for pipe-line system, and its Main Function is to prevent medium from flowing backwards, going on the pipeline of various medium.Check-valves is arranged on pipeline, namely becomes one of fluidic component of this complete pipeline, and the generation of fireproof check valve for flue, to novel high-grade house, solves a great problem.It can prevent oil smoke from flowing backwards, and can play again the interconnection function of pipeline.
Flute check valve is the security guard in family, possesses fire-proof function and lampblack-preventing pours in down a chimney two kinds of functions.It is possible to prevent common flue to concentrate the smoke blowing of each floor gap that aerofluxus causes, stop in common flue he other in the poisonous nauseating waste gas discharged pour in down a chimney in entrance own home, it is also possible to prevent the winged insects such as mosquito, moth, fly, Blatta seu periplaneta simultaneously, and the reptile such as Gekko Swinhonis enters family, it is most important that it can control the condition of a fire on alter and spread air hygiene, property life security inside guarantee family.
Fireproof check valve for flue is mainly made up of valve body and sealing blade.In use, in order to allow oil smoke and abnormal flavour better be discharged, market occurs in that flow-guiding type fireproof check valve for flue, namely one deflector is installed in check valve body, after oil smoke is discharged by check valve seal blade, due to the barrier effect of deflector, flue gas can quickly upwards shed.Simultaneously as the stop of deflector, by the flue gas up walked below flue without entering check-valves.
But, this flow-guiding type fireproof check valve for flue there is also certain drawback:
One is upper open type check valve, it is simply that sealing blade openings direction is upward.When cooking fume is discharged, blade opens, the diversed board master of blade is caused to rebound for prevent that blade from opening too big, deflector being mounted with, a long screw is as pin, the adjustable length of pin, now blade can be opened to 45 degree of-60 degree angle, but has a problem in that so, blade cannot fully open, and the exhaust air rate of whole check-valves is just had a greatly reduced quality.On the other hand, this deep bead is semienclosed, can only ensure to give vent to anger in top, and this also have impact on the exhaust air rate of check-valves to a certain extent, once exhaust air rate is big, the discharge of cooking fume will be subject to very big impact.
Also having a kind of flow-guiding non-return valve is bottom-open type, that is the opening of blade is downward, at this moment the diameter that will seek deflector needs enough big, guarantee blade can normally be opened, but owing to deflector is opening up, blade opening down, and deflector is semi-enclosed, and the output of such oil smoke, is more limited by.Further, since deflector is opening up, bottom is closed, and is exposed in the flue of building body, of long duration inevitably has a lot of refuse or sanitary fill, and this also have impact on the effect of check valve drain cigarette to a certain extent.And, once there be bulk article to fall from above, opening is easy to be blocked, and causes that check-valves cannot use.
(3) summary of the invention
Technical assignment of the present utility model is for the deficiencies in the prior art, it is provided that a kind of adjustable water conservancy diversion fireproof check valve for flue.
This utility model solves its technical problem and be the technical scheme is that
A kind of adjustable water conservancy diversion fireproof check valve for flue, including valve body, seals blade and baffle assembly, seals blade on valve body in bottom-open type structural design.
Described baffle assembly at least includes overhead gage and lower baffle plate, and overhead gage and the defined space of lower baffle plate can make sealing blade freely openable, and the dead ahead at exhanst gas outlet offers air outlet.
Further, described valve body being provided with adjustable chute, adjustable chute is vertical chute, adjustable chute is provided with screw, overhead gage or lower baffle plate and utilizes screw to be fixed on valve body.
As preferably, the length of described adjustable chute is 3-4 centimetre.
Further, being the vent of open type at least side of the left side side of baffle assembly and right side side, this vent is completely open.
Further, described sealing blade angle of freely openable in the space that overhead gage and lower baffle plate are defined is 90 degree.
Further, the back side of described valve body is provided with check blend stop also by fixing seat, and one end of check blend stop and fixing seat are hinged, and the other end of check blend stop is connected with support chip by fuse link, and support chip is fixing with fixing seat to be connected.
The adjustable water conservancy diversion fireproof check valve for flue of one of the present utility model compared with prior art, produced by provide the benefit that:
1) blade of flow-guiding non-return valve of the present utility model is bottom-open type, maximum can expand into an angle of 90 degrees, and not by the restriction of deflector diameter, oil extraction smoke is big.The problem that semi-enclosed deflector causes before solving ventilation is not smooth.This deflector left, right and dead ahead are all the vents of open type, greatly or measure little from sealing the blade not stoichiometric of oil smoke out, all can discharge smoothly very much；
2) overhead gage can block the pendant thing above flue, it is prevented that it affects the use of check-valves；Lower baffle plate can block from the oil smoke below flue, when blade uses or use of long duration can not of completely closed, can effectively tap by the oil smoke arranged up below flue, simultaneously, lower baffle plate is open, not being semi-enclosed, due to the time, on lower baffle plate, the greasy filth of accumulation can drop naturally for a long time, will not save bit by bit and affect smoke discharging effect on baffle plate；
3) adjustable chute can make check-valves adapt to the flue without diameter.In actual mechanical process, the bore of flue is not changeless, and flue diameter basic controlling is between 15cm-18cm.In the process installing fireproof check valve for flue, valve body is the indoor side at flue, and deflector is the outdoor side at flue, owing to the bore of flue is sometimes not of uniform size, so deflector must be adjustable.Adjustable chute part is a vertical chute being about three centimetres, and overhead gage is linked with valve body by a screw being arranged on chute part, when running into the flue of different bore, it is possible to adjust the position of overhead gage along chute；
4) this deflector is open type deflector, and material can be aluminum, steel iron, stainless, can save a lot of raw-material use than semi-enclosed deflector before, and both environmental protection are energy-conservation again.
