Abstract
The utility model provides a fireproof lampblack discharge check valve of a common flue. The fireproof lampblack discharge check valve of the common flue comprises a valve body and a valve plate, wherein a lampblack pass port is formed in the valve body. The fireproof lampblack discharge check valve of the common flue is characterized in that a stainless steel jacket covers on the outer peripheral surface of the valve body made from a flame retardant material; a circular seal convex side of which the upper part inclines for a 10-degree to 30-degree included angle is arranged in the lampblack pass port of the valve body; a clamping ring of which the cross section is n-shaped is assembled on the inner side of the circular seal convex side; a flame retardant seal ring of which the cross section is n-shaped is assembled on one side edge of the n-shaped clamping ring; the upper part of the valve body is connected with a hanging arm in a hinging way through a hinge; the lower end of the hanging arm is connected with the center part of the circular stainless steel valve plate through a bolt; a spring is arranged between the hanging arm and the circular stainless steel valve plate; convex lugs are installed on a connection side of the stainless steel jacket in a fixed connection way; and right angle type screw rods are connected onto the installed convex lugs. The fireproof lampblack discharge check valve has good fireproof performance, and can eliminate the fire safety potential hazards; the sealing performance is good; the valve plate is not easy to stick; the opening and closing are easy; the sealing effect cannot be reduced after long-term use; the assembly is convenient; and the cleaning and replacement are easy.
Description
Technical field
The utility model belongs to a kind of lampblack-discharging check valve, particularly a kind of common flue fire prevention lampblack-discharging check valve.
Background technique
Now each family kitchen discharged lampblack outlet of building resident, it all is a shared discharge flue that is communicated with up/down perforation, in order to prevent return of smoke and smell, general all is the anti-down return of smoke and smell check valve of inlet's installation cooking-fume discharging that connects common flue at lampblack exhauster, the many a kind of anti-down return of smoke and smell check valves of present usage comparison, its structure is by the hinged monolithic valve plate of horizontal hinge shaft at the sealed mouth of valve seat, monolithic valve plate when lampblack exhauster is not worked on the sealed mouth is closed, thereby stoped contrary oil smoke or the smell that returns in the common flue, but the major defect that this monolithic valve board structure exists is: the hinge of valve plate is not in the central position, but the position on center deviation, like this when the cigarette machine is worked, valve plate is opened, valve plate top 1/3rd indoor, 2/3rds of valve plate bottom blows to flue, imprecision when closing, not only affect daily sealing effect, simultaneously, if produce the condition of a fire in the flue, have and scurry into indoor possibility, the check valve main body is not fire-retardant, all has security against fire hidden danger; In addition, service time, valve plate was easily clung by greasy dirt, is difficult for opening when slightly long.
Summary of the invention
The purpose of this utility model provides a kind of common flue fire prevention lampblack-discharging check valve, and fireproof performance is good, eliminates security against fire hidden danger, good seal performance, valve plate is difficult for adhesion, and open and close is light, the long-term use can not reduced sealing effect yet, and be easy to assembly, cleans easily and change.
The purpose of this utility model is achieved by the following technical solution: it comprises valve body, valve plate with smoke hatch, it is characterized in that: the valve body outer circumferential face at flame retardant material coats stainless steel outer sleeve; The slope inwardly circular seal chimb of 10 ° of-30 ° of angles of top is set in the smoke hatch of valve body, is the snap ring of ∩ type at the inboard assembling of circular seal chimb cross section, be the fire-retardant seal ring of ∩ type at snap ring one side of ∩ type along the assembling cross section; By the hinged upper arm of hinge, the upper arm lower end is bolted the center portion of round stainless steel valve plate, between upper arm and round stainless steel valve plate spring is set on valve body top; Affixed mounting lug on the fillet of stainless steel outer sleeve connects the right angle type screw rod at mounting lug.
The circumferential sealing limit of above-mentioned round stainless steel valve plate is crooked to the inside.
The utility model has the advantages that: 1, valve body adopts flame retardant material to make, and the outside also coats stainless steel outer sleeve, and valve plate adopts stainless steel material to make, and fireproof performance is good, eliminates security against fire hidden danger.2, good seal performance, and common flue has abnormal pressure to raise (neighbours have the condition of a fire), valve plate contacts with fire-retardant seal ring and seal better, stop the interior pyrotechnics of flue and scurry into indoor possibility; 3, valve plate is difficult for adhesion, and open and close is light, and long-term the use can not reduced sealing effect yet; 4, the stainless steel valve plate can easily rotate on upper arm, can oscillating quantity be arranged at sealing plane again, the sealing state of energy Self-adjustment and flame retardant rubber seal ring, thus realize the optimal seal effect.4, easy to assembly, clean easily and change.

Embodiment
See Fig. 1-5, concrete structure is as follows: valve body 3 adopts fire retardant plastic material to make, and its outer circumferential face coats stainless steel outer sleeve 4; Adhering and sealing circle 10 on the sealing strip of stainless steel outer sleeve 4 contact common flue outer walls; The slope inwardly circular seal chimb 3-1 of 10 ° of-30 ° of angles of top is set in the smoke hatch of valve body 3, the snap ring 1 that is the ∩ type at circular seal chimb 3-1 assembling cross section, snap ring 1 adopts fire retardant plastic material to make, and for easy to assembly, snap ring 1 is designed with fracture; Snap ring 1 one sides edge in the ∩ type clamps the flame retardant rubber seal ring 2 that cross section is the ∩ type; Pass through hinge 12 hinged stainless steel upper arms 5 on top, valve body smoke hatch exterior edge face, upper arm 5 lower ends are connected the center portion of round stainless steel valve plate 6 with nut by bolt 7, the circumferential sealing limit of round stainless steel valve plate 6 is crooked to the inside, round stainless steel valve plate 6 can easily rotate on bolt, between upper arm 5 and round stainless steel valve plate 6, spring 13 is set, spring 13 is sleeved on the bolt 7, realize that round stainless steel valve plate 6 can easily rotate on upper arm 5, can oscillating quantity be arranged at sealing plane again, make the sealing state of its Self-adjustment and flame retardant rubber seal ring 2, reach fully sealing.Because round stainless steel valve plate 6 is in top 10 ° of-30 ° of angles that slope inwardly, thereby is in closed condition in the situation that does not have malleation wind-force.Affixed mounting lug 14 on the fillet of stainless steel outer sleeve 4, connect right angle type screw rods 8 at mounting lug 14, (see figure 1) when being assembled on the smoke exhaust port 9 of common flue is hooked the flue wall inner side surface by right angle type screw rod 8, the wing nut of tightening on the right angle type screw rod 8 gets final product, easy accessibility.
