Description

Lampblack absorber check-valves

Technical field

The utility model is related to kitchen appliance class technical field, especially lampblack absorber check-valves.

Background technology

The environmental sanitation in kitchen and people's daily life are of close concern to each other, the kitchen fume discharge of present commercial house, greatly Many to be drawn using aggregate with outliers, so oil smoke non-return is a unavoidable problem, numerous check-valves is general on Vehicles Collected from Market Using symmetric double page and asymmetric nutation type, no matter which kind of, due to its structures shape there is following two kinds of defects in it：One, Sealing is not good enough；Two, the excess loss exhausting power of lampblack absorber.

Utility model content

In order to solve the above technical problems, the purpose of this utility model is to provide lampblack absorber check-valves, including sleeve pipe, film Piece, inner handle, pin, soket head cap screw, steel ball, spring, extension bar, outdoor handle, holding screw, adjusting screw, sleeve pipe are main bodys, Circumference has two through holes being arranged symmetrically and the conical bore of steel ball positioning, and inner handle and pin insert symmetrical holes respectively；In four Hex screw is by diaphragm loaded on pin and inner handle, and inner handle can 360 ° of rotations in sleeve with dynamic diaphragm；Steel ball in spring and In the presence of adjusting screw, diaphragm is set to be properly positioned in two kinds of states of "ON" "Off"；In the hole of extension bar insertion inner handle, it is used in combination Holding screw is fastened, and the extension bar other end is inserted in part outdoor handle, fastened with holding screw, and the right-hand member of extension bar sets outdoor handle, this Drafting efficiency is high when practical lampblack absorber check-valves is opened, and good airproof performance during closing is heat-resisting, resists cold, and anti-corrosion, self lubricity is installed, Operation is simple and reliable, and good appearance is generous.

To reach above-mentioned purpose, the technical solution of the utility model is：Lampblack absorber check-valves, including sleeve pipe, diaphragm, interior hand Handle, pin, soket head cap screw, steel ball, spring, extension bar, outdoor handle, holding screw, adjusting screw, described sleeve pipe are main bodys, circle There are two through holes being arranged symmetrically and the conical bore of steel ball positioning week；The inner handle and pin are inserted in symmetrical holes respectively；Four Soket head cap screw is by the diaphragm loaded on pin and inner handle, and inner handle can 360 ° of rotations in sleeve with dynamic diaphragm；It is described Steel ball makes diaphragm be properly positioned in two kinds of states of "ON" "Off" in the presence of spring and adjusting screw；The extension bar insertion In the hole of inner handle, and fastened with holding screw, the extension bar other end is inserted in part outdoor handle, is fastened with holding screw, institute The right-hand member for stating extension bar sets outdoor handle.

The beneficial effects of the utility model are：The utility model diaphragm plane is vertical with sleeve pipe circular section, in ventilation shape State, smoking efficiency is splendid；When 90 ° of tumbler or handle, positioned by steel ball and spring automatic precision, make diaphragm disk and set Pipe circular section is parallel, realizes that full circle is sealed, and because diaphragm is cylindrical minimum with casing tube internal hole fit clearance, sealing is reliable, non-return Drafting efficiency is high when valve is opened, good airproof performance during closing, and whole parts are made using tin bronze, and its is heat-resisting, resists cold, anti-corrosion, from Lubricity is the plastics of the other like products of in the market, rubber, what galvanized sheet can not be reached, and service life is long, and installs, Operation is simple and reliable, and good appearance is generous, and using effect is good.
