Abstract
A valve body and nozzle assembly for a fire extinguisher includes a valve body that includes a nozzle connection that has a valve body threaded portion. A non-metallic nozzle includes a proximal end that has a valve body connection with a nozzle threaded portion in engagement with the valve body threaded portion. The nozzle threaded portion includes a root portion that has at least one radius of curvature extending between adjacent rows of a thread of the nozzle threaded portion.
Claims22
A valve body and nozzle assembly for a fire extinguisher comprising:
- a valve body including a nozzle connection having a valve body threaded portion and a lip defining a distal edge of an outlet of the nozzle connection;
- and
- a non-metallic nozzle comprising a nozzle body extending along a central longitudinal axis from a proximal end to a distal end, the nozzle body including an internal passage that extends uninterrupted from an inlet at the proximal end to an outlet in an end face at the distal end, and with the proximal end having a valve body connection with a nozzle threaded portion in engagement with the valve body threaded portion and the nozzle threaded portion includes a root portion having at least one radius of curvature extending between adjacent rows of a thread of the nozzle threaded portion.
A valve body and nozzle assembly for a fire extinguisher comprising:
- a valve body including a nozzle connection having a valve body threaded portion and a valve body sleeve portion;
- and
- a non-metallic nozzle including a proximal end having a valve body connection with a nozzle threaded portion in engagement with the valve body threaded portion, a nozzle sleeve portion in engagement with the valve body sleeve portion in an interference fit, and the nozzle sleeve portion is immediately adjacent the nozzle threaded portion, and wherein the nozzle sleeve portion includes at least one projection extending radially outward from an outer peripheral surface of the nozzle sleeve portion and the at least one projection is plastically deformable in a radially inward direction as the nozzle threaded portion is threaded into the valve body threaded portion.
A valve body and nozzle assembly for a fire extinguisher comprising:
- a valve body including a nozzle connection having a valve body threaded portion and a valve body sleeve portion;
- and
- a non-metallic nozzle including a proximal end having a valve body connection with a nozzle threaded portion in engagement with the valve body threaded portion, a nozzle sleeve portion in engagement with the valve body sleeve portion in an interference fit, and the nozzle sleeve portion is immediately adjacent the nozzle threaded portion, and wherein the valve body sleeve portion separates the valve body threaded portion from an outlet of the nozzle connection and a distal edge of the outlet of the nozzle connection is defined by a lip, and wherein the lip is located on an opposite side of the valve body sleeve portion from the valve body threaded portion relative to a longitudinal axis of the nozzle connection, and wherein a nozzle body of the non-metallic nozzle includes a step that transitions from an outer peripheral surface of the nozzle sleeve portion to an outermost peripheral surface of the nozzle body at a distal end of the nozzle body that has an outer dimension that is greater than an outer dimension of the nozzle sleeve portion, and wherein the step is immediately adjacent to the lip.
A valve body and nozzle assembly for a fire extinguisher comprising:
- a valve body including a nozzle connection having a valve body threaded portion and a valve body sleeve portion;
- and
- a non-metallic nozzle including a proximal end having a valve body connection with a nozzle threaded portion in engagement with the valve body threaded portion, a nozzle sleeve portion in engagement with the valve body sleeve portion in an interference fit, and the nozzle sleeve portion is immediately adjacent the nozzle threaded portion, and wherein the valve body sleeve portion includes an axial length greater than an axial length of one rotation of threads on the valve body threaded portion and, and wherein the nozzle sleeve portion has a first dimension defined by an outer peripheral surface that surrounds a central longitudinal axis defined by the non-metallic nozzle and a radially outer dimension of the nozzle threaded portion defines a second dimension that is equal to the first dimension such that threads on the nozzle threaded portion do not extend radially outward relative to the central longitudinal axis beyond the nozzle sleeve portion.
A valve body and nozzle assembly for a fire extinguisher comprising:
- a valve body including a nozzle connection having a valve body threaded portion and a valve body sleeve portion;
- and
- a non-metallic nozzle including a proximal end having a valve body connection with a nozzle threaded portion in engagement with the valve body threaded portion, a nozzle sleeve portion in engagement with the valve body sleeve portion in an interference fit, and the nozzle sleeve portion is immediately adjacent the nozzle threaded portion, and wherein the nozzle threaded portion includes a thread having a first radius at an intersection of a proximally facing threaded surface of the thread and a flat portion of a root portion and a second radius at an intersection of a distally facing threaded surface and a flat portion of another root portion, and wherein the first radius is different from the second radius.
A valve body and nozzle assembly for a fire extinguisher comprising:
- a valve body including a nozzle connection having a valve body threaded portion and a valve body sleeve portion;
- and
- a non-metallic nozzle including a proximal end having a valve body connection with a nozzle threaded portion in engagement with the valve body threaded portion, a nozzle sleeve portion in engagement with the valve body sleeve portion in an interference fit, and the nozzle sleeve portion is immediately adjacent the nozzle threaded portion, and wherein the non-metallic nozzle comprises a nozzle body extending along a central longitudinal axis from a proximal end to a distal end, and wherein the nozzle body includes an internal passage that extends uninterrupted from an inlet at the proximal end to an outlet in an end face at the distal end.
