Description
Technical field
The present invention relates to the oil smoke discharge technical field of smoke exhaust ventilator, be particularly a kind ofly convenient to the oil smoke check (non-return) valve installation component unpicking and washing maintenance fast.
Background technology
China's conventional culinary mode can produce a large amount of oil smoke, and therefore, smoke exhaust ventilator is a kind of equipment conventional in daily life.When modern building is built, be generally all provided with common flue, the oil smoke that lampblack absorber is discharged is discharged by common flue.In order to prevent the oil smoke of common flue from pouring in down a chimney, usually install oil smoke check (non-return) valve in common flue porch, check (non-return) valve is arranged on flue body of wall by screw.Because position, common flue place is narrow, after particularly fitting up furred ceiling, check (non-return) valve is difficult to dismounting usually, i.e. enable dismounting, reinstalls process also very difficult, likely needs again to fit up.But check (non-return) valve in use, likely because oil smoke sticks air door rotating shaft, or because of reasons such as mechanical breakdowns, check (non-return) valve is caused normally to use, thus affect the exhaust effect of smoke exhaust ventilator, or peculiar smell enters indoor by smoke discharging pipe, and check (non-return) valve is difficult to detachable maintaining, cleaning, causes puzzlement to daily life.
In order to solve the problem, those skilled in the art proposes all kinds of dismountable check (non-return) valve mounting means, such as publication No. be CN103123136A patent document discloses a kind of kitchen lampblack discharge system effective and easy to maintenance, comprise lampblack absorber, check (non-return) valve, smoke exhaust pipe and common flue, smoke exhaust pipe directly and common flue be tightly connected, check (non-return) valve comprises standpipe, standpipe is built-in with a circular valve block, valve block is rotatably supported on standpipe tube wall by the radial transverse axis running through valve block, standpipe tube wall is arranged a gear point, when valve block is in flat condition, be pressed on gear point under the edge of valve block, be positioned at gear point top and fix a weightening finish sheet on the valve block of gear point, the two ends up and down of standpipe are socketed with the air outlet of smoke exhaust pipe lower end and lampblack absorber respectively, socket place is fastening by anchor ear, between lampblack absorber air outlet and smoke exhaust pipe, install check (non-return) valve additional, check (non-return) valve and lampblack absorber air outlet and smoke exhaust pipe removably connect, and are convenient to disassembly, cleaning.
Again such as notification number be CN204512551U patent document discloses a kind of multiplex kitchen discharged lampblack check (non-return) valve, it comprises valve body, valve plate and the sealing strip of being with exhaust hole, valve body is that leading portion, stage casing and back segment are consisted of annular interface grafting, connection elastic hook is set at two ends, stage casing, all arranges in leading portion, section and link up with stage casing the groove linked mutually; Hinged valve plate on the exhaust hole in stage casing, in the hole of exhaust hole along assembling sealing strip; In the front end of leading portion, annular inserting groove is set; Installation muscle is set in the exhaust hole of back segment, installs on muscle and the perforation of plastics ratchet tie rod is set, an installation steel bar is set and one end is threaded onto two the plastics ratchet tie rods installed on steel bar simultaneously.This sealing structure is effective, and valve plate is adhesion not easily, and switch is light, and the port of export directly connects two kinds of installation situation that shared discharge flue or entrance point directly connect smoke exhaust and realizes general, simultaneously quick for installation, convenient, easy dismounting and cleaning.
Although the check (non-return) valve in above-mentioned two kinds of flues is detachably installed, but unloading process still comparatively bothers, and the sealing of link position and tautness are not high, the second is fragile after also there is being dismounted for multiple times by hook and groove connected mode, the shortcoming do not grown service life.
Summary of the invention
The invention provides a kind of oil smoke check (non-return) valve installation component being convenient to unpick and wash fast maintenance, there is the advantages such as structure is simple, volume is little, convenient disassembly, long service life.
Be convenient to the oil smoke check (non-return) valve installation component unpicking and washing maintenance fast, comprise:
Flue joint, is connected with common flue;
Transition conduit, is connected with the other end of flue joint;
Transition pipe joint, is connected with the other end of transition conduit;
Check (non-return) valve, valve body one end is connected with the other end of transition pipe joint;
Hose coupling, one end is connected with the other end of valve body, and the other end is connected with the smoke evacuation hose end of lampblack absorber;
One end that described transition pipe joint connects valve body has the first flange extended radially outwardly;
