Abstract
A siphon breaker includes a housing having a gas inlet and a gas outlet. The siphon breaker includes a stop valve adapted to transition from a closed position in which gas is substantially prevented from entering the gas inlet, and an open position in which gas is introduced into the gas inlet. The siphon breaker includes a control valve having a control valve gas inlet, a control valve gas outlet, and an electrically operated actuator. The control valve is adapted to transition from a closed position in which gas is substantially prevented from entering the control valve gas inlet, to an open position in which gas is through the control valve gas inlet.
Claims13
A siphon breaker, comprising:
- a housing having an interior, a gas inlet in communication with the interior, and a gas outlet in communication with the interior;
- a stop valve integral with at least a portion of the housing and adapted to transition from a closed position in which gas is substantially prevented from entering the gas inlet, and an open position in which gas is introduced into the interior of the housing through the gas inlet;
- and
- a control valve having a control valve interior, the control valve comprising a control valve gas inlet in communication with the control valve interior, a control valve gas outlet in communication with the control valve interior, and an electrically operated actuator;
- and
- wherein the control valve is adapted to transition from a closed position in which gas is substantially prevented from entering the control valve gas inlet, to an open position in which gas is introduced into the control valve interior through the control valve gas inlet.

A siphon breaking system comprising:
- a pump, having an inlet and an outlet;
- a siphon breaker, comprising:
- a housing having an interior, a gas inlet in communication with the interior, and a gas outlet in communication with the interior;
- a stop valve integral with at least a portion of the housing and adapted to transition from a closed position in which gas is substantially prevented from entering the gas inlet, and an open position in which gas is introduced into the interior of the housing through the gas inlet;
- and
- a control valve having a control valve interior, the control valve comprising a control valve gas inlet in communication with the control valve interior, a control valve gas outlet in communication with the control valve interior, and an electrically operated actuator,
- wherein the control valve is adapted to transition from a closed position in which gas is substantially prevented from entering the control valve gas inlet, to an open position in which gas is introduced into the control valve interior through the control valve gas inlet;
- and
- a conduit adapted to receive liquid flow therethrough directed by the pump, an interior of the conduit in fluid communication with the gas outlet of the housing and the control valve gas outlet, the interior of the conduit receiving gas therein when at least one of the stop valve and the control valve are in the open position.

A method for operating a siphon breaker comprising the steps of:
- providing a siphon breaker upstream of a pump operated to pump liquid through the siphon breaker, the siphon breaker comprising:
- a housing having an interior, a gas inlet in communication with the interior, and a gas outlet in communication with the interior;
- a stop valve integral with at least a portion of the housing and adapted to transition from a closed position in which gas is substantially prevented from entering the gas inlet, and an open position in which gas is introduced into the interior of the housing through the gas inlet;
- and
- a control valve having a control valve interior, the control valve comprising a control valve gas inlet in communication with the control valve interior, a control valve gas outlet in communication with the control valve interior, and an electrically operated actuator,
- wherein the control valve is adapted to transition from a closed position in which gas is substantially prevented from entering the control valve gas inlet, to an open position in which gas is introduced into the control valve interior through the control valve gas inlet;
- transitioning at least one of the stop valve and the control valve from the open position to the closed position;
- and
- introducing gas into at least one of the gas inlet housing and the control valve gas inlet of the siphon breaker.
