Problems solved by technology

When the safety valve device is bumped by external force, the check valve will be intact, protecting the liquid or gas from flowing out of the canned container, preventing fire, explosion and environmental pollution. Remove the first valve flange The disc can sweep out the residue from the valve seat, and the device is simple to manufacture and easy to maintain, but the cam of the device often contacts with the push rod during work to cause friction, and it is easy to be worn and affect the moving distance of the push rod

Abstract

The invention provides a simple safety valve device comprising a valve seat, a cam valve connected to the valve seat, and an exhaust or hydraulic valve connected to the cam valve. The valve seat is internally provided with a push rod which penetrates through the valve seat and communicates with the cam valve; and the other side, corresponding to the push rod, of the cam valve is provided with a gas or liquid pipeline connected to the exhaust or hydraulic valve connected to an exhaust port. When the simple safety valve device provided by the invention is impacted by external force, a check valve is intact and used for preventing liquid or gas from leaking out of a container, and no toxic gas, fire, explosion, air pollution or environmental pollution is caused.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a simple safety valve device. Background technique [0002] In today's world, the discharge valves of canned liquid and gas containers are all set outside the canned liquid and gas containers, without insurance mechanisms, or even made of cast iron. Liquid or gas discharge valves are prone to rupture when they are hit by external forces And fracture, the leakage of liquid cannot be blocked, causing poisoning, fire, explosion, and environmental pollution, which cannot be cleaned up. [0003] Prior art such as Chinese invention application publication document CN103161998A, a safety valve device, including a valve seat installed on the lower mouth of the canned liquid and gas container, a first valve flange connected to the valve seat, and a valve seat on the first valve flange. There is a hole on the top, an oil pipe is installed on one side of the hole, a check valve is installed...
