Problems solved by technology

[0003] A large number of accident cases show that fire and explosion accidents are frequent accidents in flammable and explosive liquid storage tank areas.
From another point of view, there are two phenomena that cannot be ignored: one is that some cables are burned, and all electric valves in the reservoir area cannot be closed electrically; the other is that there are storage tanks with flammable and explosive materials nearby.

Embodiment Construction

[0014] A hydrodynamic valve controller, characterized in that: the main body is composed of a pump body and a deceleration mechanism, each front pump cover 5 is aligned with the five fixing feet 18 on the rear pump cover 23, and fixed with bolt groups 3 to form a pump body There are water inlet and outlet pipes I1 and water inlet and outlet pipes II16 on the pump body shell, and pipe joints 2 are built in the nozzles. The other side of the pump body shell is provided with a pressure relief port 9, and the impeller 10 is installed on the front pump cover. 5 and the rear pump cover 23 are combined to form a groove, which is connected to the shaft II15 through two bearings III22, and can rotate around the axis of the shaft II15. The shaft II15 is limited by the shaft sleeve I20 and the two bearings II21. Two bearings II 21 are respectively connected with the front pump cover 5 and the rear pump cover 23, the front pump cover 5 and the rear pump cover 23 limit and support the shaft...

Abstract

A hydrodynamic valve controller is composed of a pump body and a speed reducer. When a conveying pipeline or a tank body is burnt, an electric control valve fails, firefighters cannot enter the site,the valve is closed remotely by utilizing hydrodynamic force, and a fire source is cut off or prevented from spreading; the valve close to the tank body can be opened by utilizing hydrodynamic force in case of failure of the electric control valve, flammable and combustible liquid is transferred onto a safer tank body or tank vehicle for withdrawal, and thus the fire loss is reduced or the dangersource is removed; according to user demands, residual pressure of water discharged out of an output opening is directly jet onto the conveying pipeline or the tank body to achieve the fire extinguishing effect; the personnel safety grade is improved; during later fire site treatment, the valve can be opened for post-treatment of the pipeline or the tank body without repairing a circuit firstly; selection of a power source is flexible, and both a water source carried by a fire fighting truck and a water source of a fire hydrant near a storage area can be the power source; and flowing water hasthe cooling effect and can protect the hydrodynamic valve controller against failure when the hydrodynamic valve controller gets close to a flame.

Description

Technical field: [0001] The invention belongs to the technical fields of petroleum, chemical industry, fire protection and other industries, and in particular relates to a controller for controlling a valve by using hydrodynamic force. Background technique: [0002] The storage of flammable and explosive liquids constitutes a source of danger. In these places, the risk value of accidents is high, the spread is wide, and the consequences of accidents are serious. It is necessary to focus on safety plans, safety precautions and safety solutions. [0003] A large number of accident cases show that fire and explosion accidents are frequent accidents in flammable and explosive liquid storage tank area. From another point of view, there are two phenomena that cannot be ignored: one is that some cables are burned, and all electric valves in the reservoir area cannot be closed electrically; the other is that there are storage tanks with flammable and explosive materials nearby.
