With check valve apparatus 2, tube cavity 11 is provided with inside pipe fitting 1, and check valve apparatus 2 is installed inside tube cavity 11.It
Structure is simple, easy for installation, and manufacturing cost is low, occupies little space, and 2 rapidoprint of check valve apparatus and cost of labor are lower, fill
It is smaller with part with process.
It is above-mentioned that mounting plate 100 is connected on the outside of the middle part of pipe fitting 1, mounting hole 101 is had on mounting plate 100, is convenient for
Installation；Water pipe head 3 is also set up in mounting plate 100, water pipe head 3 is spaced apart side by side with pipe fitting 1, increases function knot
Structure reduces part, is easily installed；Water pipe head 3 is formed with pipe fitting 1 and 100 integrated injection molding of mounting plate, and structure is simple, whole
Property it is strong, reduce number of parts, be easily installed and safeguard.Mainly connection cooling water channel, 3 the inside of water pipe head are not set for water pipe head 3
Set valve body.
Check valve apparatus 2 described above includes fixed block 21, spring 22, folding column 23 and diaphragm unit 24, fixed block
21 are mounted on 11 the inside of tube cavity, and folding column 23 is mounted on fixed block 21 by screw 27, is set in the middle part of folding column 23
Spring 22 is installed between fixed block 21 and folding column 21 among diaphragm unit 24, and the centre of diaphragm unit 24 is by folding column
23 are pressed on fixed block 21 and are divided into left and right two halves, and the both ends of spring 22 withstand on half diaphragm unit 24a of a left side and right half film respectively
On piece component 24b, the edge of diaphragm unit 24 and the inner wall of tube cavity 11 are engaged, its structure is simple, small in size, part
Integrated level is high, and manufacturing cost is low.Spring, for resetting diaphragm unit 24.
Above-mentioned diaphragm unit 24 is V-shaped, convenient for opening and closing to cut off or close air road.
Above-mentioned fixed block 21 is mounted on 11 the inside of tube cavity of pipe fitting 1 by gasket 25, the first screw 26, Gu
The top and bottom for determining block 21 are both provided with screw hole 211, and tube cavity 11 is protruded into the end of the first screw 26 outside pipe fitting 1
The inside is tightened in the screw hole 211 of the top and bottom of fixed block 21, the screw head and 1 outer wall of pipe fitting of the first screw 26
Between with gasket 25 seal.
It is above-mentioned that limited post 12 is set inside the tube cavity 11 at 2 rear of check valve apparatus, when left the half of check valve apparatus 2
When diaphragm unit 24a and half diaphragm unit 24b of the right side collapses, air road, half diaphragm unit 24a of a left side and right half diaphragm group are opened
Part 24b encounters limited post 12, cannot collapse again.
