Abstract
A back pressure regulator has an expanding nipple. A fluid passageway has a first inner diameter and a second inner diameter larger than the first inner diameter. The expanding nipple has an inlet connecting thread at a flow inlet for connecting to an inlet pipe and a second threaded end for connecting to a larger pipe. A reducing has a flow outlet with an outlet connecting thread to threadedly connect to an outlet pipe of the same size as the inlet pipe. A flow restrictor assembly is disposed in the reducing tee to restrict flow therethrough.
Claims18
A back pressure regulator comprising:
- an expanding nipple defining a fluid passageway having a first inner diameter and a second inner diameter larger than the first inner diameter, the expanding nipple having an inlet connecting thread at a flow inlet for connecting to an inlet pipe and a second threaded end for connecting to a larger pipe;
- a reducing tee having a rise and a run, the run defining a run inner diameter larger than a rise inner diameter, the run having a first threaded end sized to connect to the second threaded end of the expanding nipple, and the rise end defining a flow outlet having an outlet connecting thread to threadedly connect to an outlet pipe of the same size as the inlet pipe;
- a cap coupled to the reducing tee;
- and
- a flow restrictor assembly disposed in the reducing tee to restrict flow therethrough.
A back pressure regulator comprising:
- a flow inlet;
- an inlet pipe threaded to the first flow inlet, the first pipe having a first flow diameter;
- a flow outlet;
- an outlet pipe threadedly connected to the flow outlet, the outlet pipe having a second flow diameter substantially the same as the first flow diameter;
- a flow passage from the flow inlet to the flow outlet;
- the flow inlet defined on an expansion seat nipple connected to the inlet pipe;
- and
- a flow restrictor assembly positioned in the flow passage to prevent flow from the flow inlet to the flow outlet until a predetermined pressure is reached.
A back pressure regulator comprising:
- an expanding nipple defining a flow inlet;
- a reducing tee defining a flow outlet;
- and
- a flow restrictor disposed in the reducing tee between the flow inlet and the flow outlet to restrict flow from the flow inlet to the flow outlet to a maximum predetermined pressure.
