Abstract
The invention discloses a full-automatic double-side-opened pressure-maintaining unloading safety valve which is used for transporting gas and liquid media. A small water seal, a long hinge ear, a big water seal and a valve body are arranged on the front side of a double flange. A valve is arranged on the front side of the small water seal. A short hinge ear is arranged on the valve. A U-shaped water seal is arranged on the right side of the valve. A rear shaft pin and a front shaft pin connect a linkage with the long hinge ear and the short hinge ear. The long hinge ear and the rear shaft pin are vertically arranged and inclined inward 5 degrees. An oil-way of a pressure-maintaining unloading valve is communicated with an inner hole of the valve body and an inner hole of the double flange. A pressure gage is arranged on the valve body. In this way, after the full-automatic double-side-opened pressure-maintaining unloading safety valve is installed, not only can the circumferential surface of the valve be fully sealed, but also the purpose of reducing opening resistance of the valve and automatically closing of a door is achieved due to the fact that a self-weight horizontal component force serves as a driving force. The full-automatic double-side-opened pressure-maintaining unloading safety valve also can automatically maintain pressure and unload burden when a pipeline which transports the gas and liquid media is overloaded.
Description
Technical field
The invention discloses a kind of full-automatic double-side opening pressurize off-load safety valve of carrying gas and liquid medium.
Background technique
Make a general survey of the non-return equipment of domestic and international conveying gas and liquid medium, and the water supply pump house of water utility and tall building, what generally use is electric gate valve, hydraulic butterfly valve or Swing check valve, all there is complex structure in these valves, make the defectives such as difficulty and energy loss are large, up to the present, also not yet see on the market a kind of simple in structure, stable, do not want manual operation, can save the full-automatic double-side opening pressurize off-load safety valve of a large amount of manpower and materials and electric power energy.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, stable, not manual operation can either be saved a large amount of manpower and materials and electric power energy, again can be when carrying the pipeline overburdening of gas and liquid medium, the full-automatic double-side opening pressurize off-load safety valve of automatic pressure-maintaining off-load.
Technological scheme of the present invention:
a kind of full-automatic double-side opening pressurize off-load safety valve, comprise two flanges, little water seal, the band andgudgeon ear, large water seal, valve body, rear pivot pin, front pivot pin, link rod, valve, short hinge ear, the U-shaped water seal, pressurize unloading valve and pressure gauge etc., wherein: be provided with little water seal in two flanges fronts, the band andgudgeon ear, large water seal and valve body, be provided with valve in little water seal front, be provided with short hinge ear on valve, be provided with the U-shaped water seal on the left of valve, rear pivot pin and front pivot pin connect link rod and band andgudgeon ear and short hinge ear, band andgudgeon ear and rear pivot pin are vertically arranged, and slope inwardly 5 °, the oil circuit of pressurize unloading valve communicates with valve body inner bore and two flange endoporus, pressure gauge is arranged on valve body, like this, after the present invention installs, can either guarantee that the valve circumferential surface seals fully, can utilize again the deadweight horizontal component of valve to be used as power, reach the unlatching resistance that reduces valve and the purpose of automatic door-closing, can also be when carrying the pipeline overburdening of gas and liquid medium, the automatic pressure-maintaining off-load.
Key technology of the present invention is: be provided with link rod between band andgudgeon ear and short hinge ear; Band andgudgeon ear and rear pivot pin are vertically arranged, and slope inwardly 5 °, the oil circuit of pressurize unloading valve communicates with valve body inner bore and two flange endoporus, like this, the present invention can either guarantee that the valve circumferential surface seals fully after installing, can utilize again the deadweight horizontal component of valve to be used as power, reach the unlatching resistance that reduces valve and the purpose of automatic door-closing, can also be when carrying the pipeline overburdening of gas and liquid medium, the automatic pressure-maintaining off-load.
