Abstract
A vacuum sewage system includes a sump pit for receiving sewage, a valve pit, a valve, a sensor-controller, a first sensor pipe, a sump breather and a second sensor pipe. The sensor-controller activates the valve so as to discharge sewage from the sump pit. The first sensor pipe communicates pressure to the sensor-controller as the level of sewage rises within the sump pit. The second sensor pipe communicates pressure to the sump breather to move the sump breather from a first state to a second state to prevent sewage from entering the sensor-controller and valve. Alternatively, the system may be provided with a single sensor pipe that communicates pressure to both the sensor-controller and to the sump breather.
Claims21
A vacuum sewage system including:
- a sump pit for receiving sewage from a source of sewage;
- a valve pit;
- a valve located in the valve pit;
- a suction pipe having a first end connected to the valve and a second end extending into the sump pit;
- a transport pipe having a first end connected to the valve and a second end extending outside the valve pit;
- a sensor-controller located in the valve pit, the sensor-controller selectively opening and closing the valve so as to permit sewage in the sump pit to travel from the sump pit, through the suction pipe to the discharge conduit;
- a first sensor pipe having a first end extending into the sump pit and a second end extending into the valve pit, the first sensor pipe communicating increased pressure to the sensor-controller as the level of sewage rises within the sump pit;
- a sump breather;
- and
- a second sensor pipe having a first end extending into the sump pit and a second end extending into the valve pit, the second sensor pipe communicating pressure to the sump breather to move the sump breather from a first state to a second state to prevent sewage from entering the sensor-controller.
A vacuum sewage system including a sump breather apparatus, the sump breather apparatus including:
- a sensor pipe;
- and
- a sump breather, the sump breather including:
- a housing having a first member and a second member;
- a first port communicating with the interior of the housing, the first port extending from the first member of the housing;
- a diaphragm located in the housing, the diaphragm having a first side and a second side;
- and
- a switch for producing a signal indicating an abnormal state of operation of the vacuum sewage system.
