The invention discloses a rapidly-opened gate valve consisting of a valve cavity, a valve cap, a valve lock, a tightening device, a valve shaft, a gate-closing device, a damping device and an electric control system. The valve lock consists of a gate catch, a tripping electromagnet and a return spring; the tightening device consists of a main motor, a rotating rod, a bearing block, an upper plate, a large spring, a lower plate and a barrel case; the gate-closing device consists of a gate-closing motor and a top gate rod; and the damping device consist of a damping spring and a damping plate. When the valve is opened, the tripping electromagnet is electrified and actuated to pull the gate catch to move away from the gate clamping position; and under the action of air pressure in the valve cavity, the valve cap rotates around the valve shaft, rapidly turns off, retards after impacting the damping spring and finally stops. Meanwhile, the main motor reversely rotates to release a spring of the tightening device. When the valve is closed, the gate-closing motor rotates to drive the top gate rod to close the valve cap, the tripping electromagnet is powered off, the gate catch is pulled by the return spring to be clamped on the valve cap and the main motor of the tightening device forward rotates to upwards tighten the gate catch and the gate shaft. The rapidly-opened gate valve is suitable for bulking or steam explosion equipment.
Description
Technical field: [0001] The invention belongs to a quick-opening valve of the valve class. Background technique: [0002] Existing quick-opening valves include: clamp-type and gear-type quick-opening valves in which the valve cover is opened in translation, and quick-opening valves in which the valve cover is turned around the valve shaft. The fast-opening valve opened by translation has large frictional resistance, the seal is easily damaged, and the opening and closing speed of the valve is slow. The quick-opening valve that rotates around the shaft has a fast opening and closing speed, and the valve seal is not easy to wear; the disadvantage is that the valve shaft is easy to wear and the valve is not closed tightly. It cannot be used in high temperature and high pressure steam explosion equipment. Invention content: [0003] The present invention can overcome the shortcoming of above-mentioned quick opening valve. [0004] The quick-opening valve of the present inve...
