Abstract

A valve with relatively reduced tank penetration is useful for cleaning at least a portion of a filter unit, such as multiple filter bags, arranged in a filter installation for filtering polluted gas passed therethrough. This valve is preferably a relatively high performance pulse valve of relatively small pressure vessel penetration cross section area useful with relatively lower cost pressure vessels.

First claim

The invention claimed is:

1. A pulse valve comprising:
a housing having a plurality of sidewalls, a top, a base, an opening portion extending from the base and having at least one opening, and an extension extending from the opening portion, the extension having threading at an end thereof;
a pliant sealing member received in a channel in the base of the housing;
a solenoid valve mounted to the housing, with operation affecting positioning of a slideable plunger that is arranged within an interior area of the housing, the solenoid valve being electronically controlled by a control device; the pulse valve arranged within an opening in a pressure vessel containing compressed gas, and the pulse valve connected via the threading of the extension to a pipe within the pressure vessel; the pipe comprising a seal member abutting the pressure vessel, wherein the pipe is fluidly connected to nozzles for cleaning of particulate collection equipment; and
a cavity within the housing sized to accept a center extended portion of the plunger, wherein the cavity is fluidly connected to the solenoid valve, wherein the solenoid valve is operative based on measurements electronically received by the control device from sensors to generate fluid flow from a fluid supply into the cavity thereby generating a pressure within the cavity greater than a pressure of the compressed gas within the pressure vessel for a closed positioning of the plunger to block compressed gas flow from the pressure vessel through the at least one opening of the opening portion to the pipe, and
wherein the solenoid valve is operative for fluid flow from the cavity thereby generating a pressure within the cavity less than the pressure of the compressed gas in order to place the plunger in an opened position to allow for a flow of compressed gas from the pressure vessel through the at least one opening of the opening portion to the pipe for cleaning of particulate collection equipment; and
wherein the pliant sealing member creates a fluid-tight seal between the housing and an exterior surface of the pressure vessel as a result of tensile forces generated via the threaded connection between the extension and the pipe.

2. The pulse valve of claim 1 , wherein at least a portion of the pulse valve is rectangular in shape when viewed looking along an axis of travel of the plunger, is dimensioned larger in width than length, sized for arrangement within the opening of the pressure vessel.

3. The pulse valve of claim 1 , wherein the pulse valve is arranged within the opening for attachment to the pressure vessel by attachment to the pipe.

4. The pulse valve of claim 1 , wherein the pulse valve is operative for a pulse of about 10 psi to about 145 psi.

5. The pulse valve of claim 1 , wherein the sensors are selected from the group consisting of at least one of temperature sensors and pressure sensors.

6. The pulse valve of claim 1 , wherein:
the seal member is compressed between an exterior surface of the pressure vessel and a flange of the pipe as a result of tensile forces generated via the threaded connection between the pulse valve and the pipe.

7. The pulse valve of claim 6 , wherein:
the channel that receives the pliant sealing member is formed in an underside surface of the base of the housing.

8. The pulse valve of claim 1 , further comprising:
at least one tab extending laterally inward into an interior area of the opening portion, the at least one tab being configured to limit travel of the plunger moving towards the closing position.

9. A pulse valve, comprising:
a housing having a plurality of sidewalls, a top, a base having a channel in an underside surface of the base, an opening portion extending from the base and having at least one opening, and an extension extending from the opening portion, the extension having threading at an end thereof, the opening portion matingly engaging a valve opening of a pressure vessel containing compressed gas;
a pliant sealing member received in the channel in the base;
a solenoid valve mounted to the housing, with operation affecting positioning of a slideable plunger that is arranged within an interior area of the housing, and the extension connected via the threading of the extension to a pipe within the pressure vessel;
a cavity within the housing sized to accept a center extended portion of the plunger, wherein the cavity is fluidly connected to the solenoid valve, wherein the solenoid valve is operative to generate fluid flow from a fluid supply into the cavity thereby generating a pressure within the cavity greater than a pressure of the compressed gas within the pressure vessel for a closed positioning of the plunger to block compressed gas flow from the pressure vessel through the at least one opening of the opening portion to the pipe; and
at least one tab extending laterally inward into an interior area of the opening portion, the at least one tab being configured to limit travel of the plunger moving towards the closed position;
wherein the solenoid valve is operative for fluid flow from the cavity thereby generating a pressure within the cavity less than the pressure of the compressed gas in order to place the plunger in an opened position to allow for a flow of compressed gas from the pressure vessel through the at least one opening of the opening portion to the pipe for cleaning of particulate collection equipment; and
wherein the pliant sealing member creates a fluid-tight seal between the housing and an exterior surface of the pressure vessel as a result of tensile forces generated via the threaded connection between the extension and the pipe.
