Detailed description of the invention
The present invention provides a kind of oxygen cleaning valve rod, refers to shown in Fig. 1 to Fig. 4, and this oxygen cleaning valve rod 100 includes: by moulding
Valve rod 3 that the bolt 2 that the handle 1 made of material is connected with this handle 1 is connected with this bolt 2, it is set in outside this valve rod 3
And be positioned at the valve body 10 of this valve rod 3 lower end, be set in this valve rod 3 upper end and the cap 4 threadeded with valve rod 3, sheathed
The first stainless steel gasket 5 of being fixed on valve rod 3 and by cap 4, all it is set between valve rod 3 and valve body 10 and is close to
The first cushion film 6 and the second cushion film 7, be set on valve rod 3 and be connected to the second rustless steel on the second cushion film 7
Pad 8, the spool being set in valve body 10 upper end and the stator 9 threadeded with valve body 10, being connected to valve rod 3 end
11, it is threadedly secured in the nut 12 of valve body 10 both sides, is connected between valve body 10 and nut 12 and is used in conjunction with each other
Front cutting ferrule 13 and rear cutting ferrule 14.
Wherein, handle 1 is plastic circular handle, and its external form is airflow design, matches with human body palm；This handle 1
Lateral surface be provided with multiple anti-slip tanks 111 of equidistantly arrangement；This valve body switch direction is illustrated on this handle 1.Work as rotation
During handle 1, band ovable valve stem 3 lifts.
Bolt 2 connects handle 1 and valve rod 3, and bolt 2 prevents handle 1 from coming off.
Valve rod 3 surface is provided with electrosilvering, and valve rod 3 has fabulous self-lubricity, effectively reduces the torsion of valve body switch,
Extraordinary performance is had in impression using.The upper end of valve rod 3 is connected with handle 1, and the lower end spool 11 of valve rod 3 connects.
When handle 1 band ovable valve stem 3 rotates, and the spool 11 of connection lifts with valve rod 3 in the lump, plays the effect of open and close valve.
Cap 4 is connected with valve body 1 threaded upper ends, and this cap 4 is positioned on stator 9.Cap 4 is used for extruding valve body
Inner sealing gasket 6,7, is allowed to play the effect of sealing.
First stainless steel gasket 5 is acting between cap the 4, first cushion film 6 and the second cushion film 7, and this is first not
Rust steel plate washer 5 extrudes the first cushion film 6 and the second cushion film 7 together with coordinating with cap 4.
First cushion film 6 and the second cushion film 7 are used to seal valve rod 3.
Second stainless steel gasket 8 is positioned at below the second cushion film 7, and this second stainless steel gasket 8 is as the first cushion film 6 He
Second cushion film 7 active force face.Second stainless steel gasket 8 is between valve body 10 and valve rod 3.
Stator 9 is positioned at the lower end of cap 4.
Valve body 10 is needle valve body, and needle-valve blocks/flow through the key mastery reaction of liquid.Valve body 10 includes: be set in
This valve rod 3 is outer and has the first sidepiece 102 and second that externally threaded upper part 101 is connected with this upper part 101 side
Sidepiece 103；Wherein, it is provided with through hole 104, valve between this upper part 101 and the first sidepiece 102 and second sidepiece 103
