Description
Technical field
The utility model belongs to plate valve field, particularly forged steel pipeline soft seal plate valve.
Background technique
Plate valve widely uses at oil, rock gas, chemical field, has been a kind of standardised generic product.In general, the slide-valve of plate valve to be a kind of closure member be parallel gate plate.Its closure member can be Single disc or therebetween with the double-flashboard of spreading mechanism.Flashboard is controlled by the pressure medium of effect with floating flashboard or floating valve seat to the impacting force of valve seat.If Double Disc Flat Gate Valves, then the spreading mechanism between two flashboards can supplement this impacting force.
Plate valve flow resistance is little, and its flow resistance and the short flow resistance by all means of not reducing are similar.Plate valve with pod apertures is arranged on pipeline also can carry out pigging by direct wiper.Because flashboard slides on two valve seat surfaces, therefore plate valve liquid can be applicable to be with the medium of suspended particulate, the sealing surface of plate valve to be actually location automatically.Sealing surface of seat can not be subject to the damage of valve body thermal distortion.Even if valve is closed under cold state, the thermal stretching of valve rod also can not make sealing surface be transshipped.When the valve is closed, the plate valve without pod apertures does not also require that the close stance of flashboard is equipped with higher precision simultaneously, and therefore driven plate valve available travel controls to open and close position.
Sealability between the valve seat of present forged steel pipeline soft seal plate valve and flashboard is bad, causes there will be leakage when using.
