Abstract
An internal valve including a body having a first end configured to be disposed within a tank and a second end configured to be disposed outside of the tank. The body includes a shoulder configured to be positioned adjacent to a mounting surface of the tank, a single flange positioned between the shoulder and the second end, a plurality of primary struts connecting an interior of the body to an internal primary stem guide, and a plurality of secondary struts connecting the interior of the body to an internal secondary stem guide. The primary struts and the primary stem guide are positioned between the flange and the shoulder, and the secondary struts and the secondary stem guide are positioned between the shoulder and the first end.
Claims21
A valve, comprising:
- a body having a first end that is configured to be disposed within a tank and a second end that is configured to be disposed outside of the tank, wherein the body comprises:
- a shoulder that is configured to be positioned adjacent to a tank mounting surface of the tank;
- a single flange that is positioned between the shoulder and the second end;
- a plurality of primary struts that connect an interior of the body to an internal primary stem guide, wherein the plurality of primary struts and the primary stem guide are positioned between the flange and the shoulder;
- and
- a plurality of secondary struts that connect the interior of the body to an internal secondary stem guide, wherein the plurality of secondary struts and the secondary stem guide are positioned between the shoulder and the first end;
- a stem that is slidably positioned within the internal primary and secondary stem guides;
- a poppet body that is slidably coupled to the stem, wherein the poppet body is configured to engage the first end in a first operating state and to be spaced away from the first end in a second operating state;
- and
- an excess flow spring configured to be disposed within the body and to bias the poppet body toward the first end.
A valve, comprising:
- a body having a first end that is configured to be disposed within a tank and a second end that is configured to be disposed outside of the tank, wherein the body comprises:
- a shoulder that is configured to be positioned adjacent to a tank mounting surface of the tank;
- a single flange that is positioned between the shoulder and the second end;
- a plurality of primary struts that connect an interior of the body to an internal primary stem guide, wherein the internal primary stem guide has a first inner diameter;
- and
- a plurality of secondary struts that connect the interior of the body to an internal secondary stem guide, wherein the internal secondary stem guide has a second inner diameter smaller than the first inner diameter;
- a stem that is slidably positioned within the internal primary and secondary stem guides;
- and
- a poppet body that is slidably coupled to the stem, wherein the poppet body is configured to engage the first end in a first operating state and to be spaced away from the first end in a second operating state.
A valve body for a valve, comprising:
- a first end that is configured to be disposed within a tank;
- a second end that is configured to be disposed outside of the tank;
- a shoulder that is configured to be positioned adjacent to a tank mounting surface of the tank;
- a single flange that is positioned between the shoulder and the second end;
- a plurality of primary struts that connect an interior of the body to an internal primary stem guide, wherein the plurality of primary struts and the primary stem guide are positioned between the flange and the shoulder, and wherein the internal primary stem guide has a first inner diameter;
- and
- a plurality of secondary struts that connect the interior of the body to an internal secondary stem guide, wherein the plurality of secondary struts and the secondary stem guide are positioned between the shoulder and the first end, and wherein the internal secondary stem guide has a second inner diameter smaller than the first inner diameter.
