Just, the more preferable regulating valve special for chlorine of sealing property.
The present invention adopts the following technical scheme that and completes: regulating valve special for chlorine, including valve body, valve gap and valve rod,
The lower end of valve rod is provided with spool, and fairlead is arranged in valve pocket, and the upper end of fairlead presses closer valve gap lower end, described fairlead
Lower end presses closer on the first annular step surface of valve seat, and described fairlead top has the second annular table terrace, under described valve gap
Holding corresponding second annular table terrace to be provided with the 3rd annular table terrace, described 3rd annular table terrace is clamped on the second ring-shaped step
On face, the low order plane of described valve body upper end and the second annular table terrace maintains an equal level, the projection of described 3rd annular table terrace towards
Under be pressed on valve body upper end and the second annular table terrace, described crowning lower end is lined with sealing gasket, and described valve gap and valve body are adopted
Connecting with flange, after connection, described valve gap is pressed on downwards on upper end and the sealing gasket of fairlead.
The regulating valve special for chlorine that the present invention provides uses the downward compressing guide sleeve of valve gap and sealing gasket, have again fairlead to
Lower compression valve seat, makes valve seat, fairlead and valve gap form one and installs overall, install and fixed structure is extremely simple, install and
Dismantle convenient, and promote whole valve gap and the place of cooperation of valve body to form valve gap and valve body, close at valve gap and fairlead two
Envelope, can be better protected from material from leakage.
