Abstract
The invention provides an electric pipeline rapid safety valve with an automatic power-failure reset function. The safety valve is characterized in that a valve rod is sequentially provided with a suspension arm and an electromagnetic clutch reset device, wherein a counterweight is hung on the suspension arm, and a main control box is arranged on the upper part of a drive device; the opening/closing of the valve is controlled through a signal transmitted by a control system of the main control box, the valve generally stays at an open state, when the pressure of a pipeline is extremely low or gas is leaked from the pipeline, a pressure alarming sensor on the pipeline transmits a signal to the control system of the main control box, the control system compares the received signal with a set value to transmit a control signal, so that the drive device is actuated, and the valve can be rapidly opened/closed. The electric pipeline rapid safety valve has the beneficial effects that the pipeline can be accurately and timely cut off or opened when in emergency, the rapid safety valve of the pipeline can be closed/opened when in power failure, and the secondary disaster can be avoided. The rapid safety valve is reasonable in structure, sensitive and reliable to operate, convenient to maintain, and high in action speed, and is a necessary safety device in the gas stove control of the industries such as metallurgy, petrochemical, power stations and building materials.
Description
Technical field
The present invention relates to the electronic fast and safely valve of pipeline, the electronic fast and safely valve of especially a kind of pipeline with power-off auto-reset function.
Background technique
Safety valve belongs to self-acting valve class; be mainly used on boiler, pressure vessels and pipes; pilot pressure is no more than specified value; important protective action has been run to personal safety and equipment; as the instrument that a class is common and conventional; the market application area of safety valve is very wide, and its Reliability of Microprocessor and performance quality are directly connected to the safety of equipment and the person.
Along with the environmental consciousness of people and the enhancing of social responsibility, national environmental protection policy perfect, rock gas, coal gas, in generating, the industry such as metallurgical and in the people's livelihood, instead of the coal that can cause heavily contaminated, obtain and use more and more widely.Rock gas, coal gas all belong to flammable explosive gas, how safety use they, become a new problem.
For metallurgy industry, the sintering furnace of Iron And Steel Plant is exactly the use rich and influential family of by-product gas (blast furnace gas, coke-stove gas, coal gas of converter), if because misoperation or safety at power cut to cause in pipeline gas pressure lower than requiring pressure, and in burner hearth, have elevated pressures, when furnace temperature is higher, the coal gas of burning by burner to gas pipe line combustion, will cause back-fire trouble, namely Professional visitors's ' low pressure tempering ' of often saying.Once cause ' low pressure tempering ', be easy to make pipeline burst, even cause personal injury, when therefore breaking down, the coal gas in the rapid cutting out pipeline of energy is particularly important.
In the people's livelihood, heat supply in winter boiler has all carried out the transformation of ' coal changes gas ' substantially, and that is rock gas has become the main fuel of heating boiler, and natural gas line is once leak, and ducts upstream should have quick cutting device to be cut off by rock gas rapidly.Especially, when extreme case occurs, as the major disasters such as fire, earthquake or flood cause power failure, general electric safety device cannot work, thus cause larger secondary disaster.
Based on the particularity of rock gas, coal gas, the industry regulation in this field is that gas-fired equipment puts into operation and must arrange quick electric safety valve at present, otherwise will not allow to use.But the design of quick electric safety valve in the special emergency safety devices such as power-off also belongs to blank, safety valve energy action rapidly while power-off of exploitation band power-off restoration function, effectively controls secondary disaster, the property life safety of man of the protectorate people.Can be widely used in and need, on emergency cut-off or the various industry of opening or civilian pipeline, to there are wide market prospects.
Summary of the invention
Object of the present invention is exactly the deficiency for prior art aspect, and can have rapid holding function when being provided in powering-off state generation, controls the close/open of safety valve, and after Failure elimination, can be restored to original state.Solve the safe handling problem of the flammable explosive gas such as rock gas, coal gas further, can timely and accurately by pipe cutting or open at Emergency time, especially in power-cut time, still can by pipeline valve close/open when lacking power source, to ensure pipe safety, avoid the generation of secondary disaster.
Technical solution of the present invention is to provide the electronic fast and safely valve of a kind of pipeline with power-off auto-reset function, this safety valve comprises the valve containing valve body, valve plate, valve rod, and be connected on the pipeline of setting pressure alarm sensor, wherein: this safety valve also comprises Main Control Tank, driver, clutch reset device, mass, described valve rod is disposed with upper arm, electromagnetic clutch resetting means, described mass hangs in upper arm, and described Main Control Tank is located at the top of driver; The close/open of described valve sends signal by the control system of Main Control Tank, usual valve is in open mode, when there is hypotony in pipeline or has gas to leak outside, pressure warning sensor on described pipeline will send signal to the control system of Main Control Tank, control system sends control signal after comparing with setting value, make driver action, thus rapid close/open valve, when occurring when there being extreme case causing power failure, driver is departed from valve, and valve can instantaneous close/open valve under the effect of mass.
Effect of the present invention is: adopt the electronic fast and safely valve of this pipeline can timely and accurately by pipe cutting or open at Emergency time, especially in power-cut time, still by this fast and safely valve closedown of pipeline or can open when lacking power source, to ensure pipe safety, avoid the generation of secondary disaster.Fast and safely valve solves the safe handling problem of the flammable explosive gas such as rock gas, coal gas further.This fast and safely the upper arm of valve, mass arrange and have rational in infrastructure, manual dexterity is reliable, and easy to maintenance, the features such as quick action are indispensable safety installation in the gas range control system of the industries such as metallurgy, petrochemical industry, power station, building materials.
