The invention discloses a high-safety aluminum valve comprising a valve body and a valve ball. A flow channel is formed in the valve body. A conical valve hole matched with the valve ball is formed inthe middle of the flow channel. The valve body is provided with a jacking rod acting on the valve ball, and provided with an inlet communicating with the upper portion of the flow channel and an outlet communicating with the lower portion of the flow channel. A spring seat is arranged in the outlet and provided with a spring for pushing the valve ball to seal the conical valve hole. A through hole is formed in the spring seat. A rotationally-connected valve plate is arranged at the lower end of the through hole. A valve rod acting on a valve plate to open the valve plate is arranged on the lower portion of the valve ball. According to the high-safety aluminum valve, leakage of a fire extinguishing agent is reduced.
Description
technical field The invention belongs to the field of fire protection, in particular to a high-safety aluminum valve. Background technique At present, fire-fighting equipment such as a fire extinguisher is usually provided with a valve, and the handle is used to operate the valve to open or close. For example, Chinese Patent Publication No. CN106678441A discloses a low-temperature fire extinguisher valve structure, including a valve body; The outlet of the valve body connected with the main channel, the lower port of the main channel constitutes the inlet of the valve body, the main channel includes a tapered valve hole whose inner diameter gradually decreases from bottom to top; and the valve core used to control the flow channel of the valve body The valve core includes a valve stem inserted in the main channel, an upper valve stem sealing ring arranged on the valve stem and forming a sealing connection with the main channel, and a valve stem lower sealing ring arranged o...
