Description
Technical field
This utility model relates to a kind of ball valve, is specifically related to a kind of flange form Fluorine-lined ball valve.
Background technology
Ball valve of the prior art generally includes valve body, valve seat, spool, valve rod and spanner, and spanner realizes the opening and closing of valve body after driving valve core rotation certain angle by valve rod.In special application scenario, ball valve is had the requirement of anticorrosion and avoiding improper opening.
Summary of the invention
The purpose of this utility model is to provide a kind of flange form Fluorine-lined ball valve being applicable to Korrosionsmedium and being prevented from maloperation.
The technical scheme that this utility model is taked is:
A kind of flange form Fluorine-lined ball valve, including valve body, the both sides of valve body are provided with charging and discharging mouth, being provided with valve seat and ball-type spool in valve body, valve seat is installed between spool and valve body, and the top of spool is provided with valve rod, valve rod stretches out in the valve rod hole of body top, being filled with filler in valve rod hole, valve rod is cased with spring and hex nut, spring is squeezed between filler and hex nut；Spacing spanner is installed on the external part of valve rod, described spacing spanner includes position-arresting disk and spacer pin, position-arresting disk is fixedly installed in body top, the spacing hole that a circle is uniform is set on position-arresting disk, spacer pin includes draw ring and spring catch, described spring catch is vertically arranged in the pin-and-hole of spanner, and draw ring is connected to spring catch top, and when spanner band ovable valve stem rotates, spring catch coordinates spacing with spacing hole.
Further, the surface of described body cavity machine spool is all lined with F46.
After taking above technical scheme, the beneficial effects of the utility model are:
The inside and outside wall of spool, the inwall of valve body are all lined with F46, it is possible to be applicable to the use occasion of high-corrosion medium；Utilize the cooperation of spring catch and limit pin hole, be both avoided that to open by mistake and opened, can preferably control again open degree.
