Technical field
The utility model relates to a kind of high pressure gas reducing valve.
Background technique
Rock gas is used widely as clean energy resource, usually the method for supplying of fuel has three kinds: (1) delivers to the user by urban pipe network, (2) LNG Liquefied natural gas is given the user after gasification, and (3) high-pressure gaseous rock gas, after the decompression pressure regulation, is given the user.In these three kinds of methods of supplying, urban pipe network construction investment large period is long, and LNG Liquefied natural gas is just to have occurred recent years, and the source of the gas cost is high, expensive.So the high-pressure gaseous rock gas is because apparatus and process is simple, the little investment instant effect, be usually used in the city air feed away from natural air-air source, or the user's air feed do not reached to gas ductwork in city.The characteristics of this plenum system are: gaseous natural gas is to carry at normal temperatures, can not be as liquefied petroleum gas (LPG), with liquid accumulating, under normal temperature, store while transporting rock gas, generally be pressurized to the 200bar left and right, increase its conveying capacity, so must, by the decompression voltage adjusting device, reduce to the pressure that a stable user needs to pressure when utilizing this high-pressure natural gas.Be applied at present the most complex structure of reduction valve of high-pressure gaseous rock gas, poor reliability, effect of easing stress and actual requirement difference are larger, have affected effect of easing stress.
The model utility content
The technical problems to be solved in the utility model is to overcome above-mentioned defect, and a kind of simple in structure, high pressure gas reducing valve that effect of easing stress is good is provided.
For addressing the above problem, the technological scheme that the utility model adopts is:
A kind of high pressure gas reducing valve, comprise valve gap, the valve body be connected with valve gap, the both sides of valve body are provided with suction port and air outlet, suction port and air outlet are by being arranged on the channel connection in valve body, it is characterized in that: described valve gap upper end is provided with the automatic control power device, and the automatic control power device is connected with the drive link perpendicular to passage, and drive link runs through the joint of valve gap and valve body; Described drive link is connected with decompressor, and is provided with decompressing groove in valve body, and decompressor is positioned at decompressing groove; The diameter of described passage is less than the width of decompressing groove, and the access portal of passage and decompressing groove joint is all in decompressing groove.
As a kind of improvement, described decompressor comprises the connecting plate be fixedly connected with the connecting rod lower end, and connecting plate is movably connected in valve body; The lower end surface of described connecting plate is elasticly connected with flexible connection piece, and the two ends of flexible connection piece are fixed in valve body; Be fixed with flap on the lower end surface of described flexible connection piece, flap is arranged in decompressing groove and matches with passage.
As a kind of improvement, between described connecting plate and flexible connection piece, by spring, be connected.
As a kind of improvement, described automatic control power device comprises the control box that is arranged on the valve body upper end, is provided with controller in control box, in described valve gap, motor is installed, and motor is electrically connected to controller, and motor-driven connection for transmission bar.
Owing to having adopted technique scheme, compared with prior art, the utility model is starting electrical machinery when decompression, the motor pushing drive link moves downward, and drive link drives connecting plate, and connecting plate drives flexible connection piece, flexible connection piece drives flap and moves downward, flap is blocked the part of passage downwards, reduces the flow of LNG Liquefied natural gas, thereby reaches the purpose of decompression.After decompression, utilize flexible connection piece can realize resetting fast, guarantee the carrying out of action next time.The utility model is simple in structure, is convenient to produce and maintenance, has also guaranteed effect of easing stress, is convenient to promote simultaneously.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail simultaneously.
