Abstract
A modular lining system for a valve body for use in fluid handling systems including fluid transport tankers, and a method for lining a valve body using the modular lining system. The lining system is slidably inserted into the valve body to protect the valve body from corrosive or other damaging materials. The liners are placed such that they are easily removable for cleaning or replacing when damaged. An actuator comprising a piston is actuated within one of the liners to selectively allow and stop fluid flow.
Claims20
A valve comprising:
- a valve body comprising a tubular first body portion having a first end and a second end, and a tubular second body portion affixed to and intersecting the first body portion, the second body portion having a first end distal from the first body portion;
- a tubular first lining removably positioned in the first body portion;
- a tubular second lining removably positioned in the second body portion, the second lining sealingly engaging an aperture in the first lining;
- and
- an actuator removably attached to the first end of the first body portion or the first end of the second body portion, the actuator comprising means for selectively stopping and allowing fluid flow through the valve.
A valve comprising:
- a valve body comprising a cylindrical first body portion having an outlet end and an actuator attachment end, and a cylindrical second body portion affixed to and intersecting the first body portion, the second body portion having an inlet end distal from the first body portion;
- a cylindrical first lining removably positioned in the first body portion and extending from the outlet end to the actuator attachment end of the first body portion;
- a cylindrical second lining removably positioned in the second body portion, the second lining sealingly engaging an aperture in the first lining, the second lining extending from the engagement with the first lining to the inlet end of the second body portion;
- and
- an actuator removably attached to the actuator attachment end of the cylindrical first portion, the actuator comprising a cylindrical, piston sealingly moveable within the first lining of the first body portion for selectively stopping and allowing fluid flow between the inlet and the outlet.
A method of assembling lining into a valve body comprising a cylindrical first body portion having a first end and a second end, and a cylindrical second body portion intersecting the first body portion, the second body portion having a first end distal from the first body portion, the method comprising the steps of:
- slidably inserting a non-metallic first lining into the outlet end of the first body portion such that the first lining extends from the outlet end to the actuator attachment end of the first body portion;
- slidably inserting a non-metallic second lining into the inlet end of the second body portion such that the second lining sealingly engages an aperture in the first lining and such that the second lining extends from the sealed engagement with the first lining to the inlet end of the second body portion;
- slidably inserting a non-metallic piston of an actuator into the first lining or the second lining;
- and
- attaching the actuator to the end of the corresponding body portion.
