Abstract

A serviceable double block and bleed valve is provided, having a futbol, and having an integral body having two block valves and one bleed valve and a flange on its inlet end which is bolted to a mating flange of the futbol The double block and bleed valve is installed on the process pipe by welding of the inlet of the futbol to the process pipe, while servicing or replacement of the integral body or any parts associated therewith is achieved through removal of the bolts holding the mating flanges together.

Claims

1. A double block and bleed valve for installation on a process pipe, the double block and bleed valve comprising:

an inlet for providing fluid communication of the valve to the process pipe;

an inlet flange defined about the inlet; and

a futbol having a futbol flange at one end for mating with said inlet flange, and having a futbol inlet for mounting to the process pipe.

5. A method of installing the double block and bleed valve as defined in claim 1 on a process pipe, the method comprising:

securely bolting the inlet flange to the futbol flange; and

welding the futbol inlet to the process pipe.

8. A method of disassembly of an installed double block and bleed valve as defined in claim 1, the method comprising:

unbolting the inlet flange from the futbol flange; and

unmating the inlet flange from the futbol flange.

2. A double block and bleed valve for installation on a process pipe, the double block and bleed valve comprising:

an integral body comprising an inlet, an outlet, a vent, an inner channel in fluid communication with the inlet, the outlet, and the vent;

a first block valve between the inlet and the inner channel;

a second block valve between the outlet and the inner channel;

a bleed valve between the inner channel and the vent;

an inlet flange defined about the inlet; and

a futbol having a futbol flange at one end for mating with said inlet flange, and a futbol inlet at an other end for mounting to the process pipe.

3. A double block and bleed valve kit for installation on a process pipe, the double block and bleed valve kit comprising:

an integral body having an inlet for providing fluid communication of the valve to the process pipe, an inlet flange defined about the inlet; and

a futbol having a futbol flange at one end for mating with said inlet flange, and having a futbol inlet for mounting to the process pipe.

4. A double block and bleed valve kit according to claim 3 further comprising a plurality of flange bolts for securing the inlet flange to the futbol flange.

6. A method of installing the double block and bleed kit as defined in claim 3, the method comprising:

securing the integral body to the futbol by bolting the inlet flange to the futbol flange with a plurality of flange bolts; and

mounting the futbol inlet of the futbol to the process pipe.

9. A method of disassembly of an installed double block and bleed kit as defined in claim 3, the method comprising:

separating the integral body from the futbol by unbolting the inlet flange from the futbol flange; and

unmating the inlet flange from the futbol flange.
