Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain this
Utility model, is not used to limit this utility model.
Referring to Fig. 1, the aqueous vapor control valve 100 that this utility model preferred embodiment is provided, including valve body 10, import connects
20, outlet connection 30, gas control joint 40, piston 50 and movable valve plug 60, wherein said inlet union 20 is arranged on valve body 10
A side end, import water or gas in this valve body 10 in the past, described outlet connection 30 is fixed on the sidewall of valve body 10, and
The water or the gas that are imported by inlet union 20 being derived, described piston 50 and movable valve plug 60 are fixed in valve body 10,
And the pipe passage being jointly connected inlet union 20 with outlet connection 30 carries out opening and closing sealing, and described gas control joint 40 is
It is fixed on the end side of valve body 10, and is specifically driven piston 50 and movable valve plug 60 controlling.
In the present embodiment, described inlet union 20 is to be fixedly connected with valve body 10 threadably, and this import
Sealing with the first gasket seal 21 between joint 20 and valve body 10, wherein said first gasket seal 21 is provided in
The position that described valve body 10 abuts against with inlet union 20；Described outlet connection 30 is also to fix with valve body 10 threadably
Connect, and seal with the second gasket seal 31 between described outlet connection 30 and valve body 10, wherein said second
Gasket seal 31 is provided in the position that described valve body 10 abuts against with outlet connection 20；Described gas control joint 40 is also with spiral shell
Stricture of vagina mode and valve body 10 be fixing to be connected, and is to carry out close with the 3rd gasket seal 41 between described gas control joint 40 and valve body 10
Envelope, wherein said 3rd gasket seal 41 is provided in the position that described valve body 10 abuts against with gas control joint 40.Permissible
Understanding, the aqueous vapor control valve 100 of the present embodiment is by with the first gasket seal the 21, second gasket seal 31 and the 3rd sealing gasket
Sheet 41 to inlet union 20 and valve body 10, is carried out between outlet connection 30 and valve body 10 and gas control joint 40 and valve body 10 respectively
Seal, it is ensured that this integrally-built sealing property of aqueous vapor control valve 100.
In order to realize this piston 50 and time movable valve plug 60 works to the connection between inlet union 20 and outlet connection 30
Pipe passage carries out opening and closing sealing, and the present embodiment arranges a step 11 in valve body 10, and described piston 50 is positioned adjacent to gas control
The side of joint 40, and spacing firmly by step 11, that is described piston 50 is arranged on the side that this valve body 10 medium caliber is bigger；And
