Abstract
A water strainer, water meter, and crossover check valve structurally and functionally integrated within a single housing having a single access port. A water strainer, including a screened portion and a solid floor, diverts debris from the water flow path into a collection chamber in the bottom portion of the housing. The water strainer defines an interior volume within the housing, designed to pass strained water and protect the impeller assembly of the water meter located therein. A strainer outlet pipe, extending from an outlet port into the interior volume of the housing, may be included to house both the impeller and the check valve. The single access port provides for service of the interior components and removal of collected debris.
Claims15
In combination, a fluid flow meter and strainer, comprising:
- a. a housing, having an inlet port and an outlet port defining a fluid flow path therebetween, said housing further including an access port in a wall of said housing intermediate said inlet and outlet ports;
- b. strainer means for retaining solid particles and allowing passage of said fluid flow path therethrough, said strainer means defining an interior volume surrounding said outlet port, and further defining an exterior volume between said strainer means and said inlet port, for the collection of solid particles;
- c. a strainer lid covering said access port, for allowing selective access into said interior volume;
- and,
- d. metering means located within said interior volume of said strainer means and positioned therein to intercept at least a portion of said fluid flow path, for measuring the rate of fluid flow through said housing.
In combination, a fluid flow meter and strainer, comprising:
- a. a housing, having an inlet port and an outlet port defining a fluid flow path therebetween, said housing further including an access port in a wall of said housing intermediate said inlet and outlet ports;
- b. a strainer outlet pipe located within said fluid flow path, having a discharge end connected to said outlet port, and an infeed end extending interiorly within said housing;
- c. strainer means for retaining solid particles and allowing passage of said fluid flow path therethrough, said strainer means surrounding at least said infeed end of said strainer outlet pipe to define an interior volume, and further defining an exterior volume between said strainer means and said inlet port, for the collection of solid particles;
- d. a strainer lid covering said access port, for allowing selective access into said interior volume;
- and,
- e. metering means within said strainer outlet pipe, for measuring the rate of fluid flow through said housing.
In combination, a fluid flow meter, a strainer, and a check valve, comprising:
- a. a housing, having an inlet port and an outlet port defining a fluid flow path therebetween, said housing further including an access port in a wall of said housing intermediate said inlet and outlet ports;
- b. a check valve, having an inlet side and an outlet side;
- c. a strainer outlet pipe, having a downstream end connected to said outlet port and an infeed end extending interiorly within said housing;
- d. means for detachably securing said outlet side of said check valve to said infeed end of said strainer outlet pipe;
- e. a strainer outlet pipe extension, having an inflow end and an outflow end, said outflow end being maintained in snug relation over said inlet side of said check valve;
- f. strainer means for retaining solid particles and allowing passage of said fluid flow path therethrough, said strainer means defining an interior volume surrounding said inflow end of said strainer outlet pipe extension, and further defining an exterior volume between said strainer means and said inlet port, for the collection of solid particles;
- g. a strainer lid covering said access port, for allowing access into said interior volume and to said check valve;
- and,
- h. metering means within said strainer outlet pipe extension, for measuring the rate of fluid flow through said housing.
