Abstract
A pressure regulating valve structure is described. The pressure regulating valve structure may include a valve body, an air inlet channel arranged in the valve body, and a valve stem movably arranged in the air inlet channel and configured to open or close the air inlet channel. In normal conditions, the air inlet channel is open.
Claims38
A pressure regulating valve structure comprising:
- a valve body,
- an air inlet channel arranged in the valve body, and
- a valve stem movably arranged in the air inlet channel and configured to open or close the air inlet channel,
- wherein the air inlet channel is in an open state under normal conditions,
- wherein the valve stem is connected to a linkage rod, and
- wherein the linkage rod is connected to a pressure valve diaphragm, the pressure valve diaphragm is installed on the valve body, and a closed compression space is formed between the pressure valve diaphragm and the valve body, and the closed compression space is connected to an outside of the valve body.

A pressure regulating valve structure, comprising:
- a valve body comprising:
- an air inlet channel,
- an air outlet channel, and
- a compression space fluidly connected to an outside of the valve body;
- a linkage rod pivotally connected to the valve body,
- a valve stem movably positioned within the air inlet channel and connected to the linkage rod, the valve stem equipped with a seal configured to open and close the air inlet channel, and
- a pressure valve diaphragm indirectly connected to the valve stem via the linkage rod and configured to displace within the compression space,
- wherein an airflow from the air outlet channel through the air inlet channel circumvents the seal.

A pressure regulating valve structure, comprising:
- a valve body comprising:
- an air inlet channel,
- an air outlet channel, and
- a plurality of compression spaces fluidly connected to an outside of the valve body;
- a linkage rod movably connected to the valve body,
