Abstract

The utility model relates to a fireproof ball valve, which comprises a lower cover, springs, a valve seat, folio rings, a valve body, a valve cover and the like. The contact part of the big end of an upper valve rod and the valve body is provided with two folio rings; the valve seat has a combined structure and is embedded into a valve seat bracket; the sealing between the valve seat bracket and a pressing ring is realized by using a graphite sealing gasket; and the springs evenly distributed at the bottom of the pressing ring push the valve seat towards a ball. The valve has a two-piece type flange connection structure, has a quick cooling speed, is abrasion resistant and corrosion resistant, has a long service life, is safe and fireproof, and is convenient for users to mount and use.

Description

Novel fire prevention ball valve
Technical field:
The utility model relates to a kind of ball valve, especially between upper valve rod major part and the valve body, is equipped with two and splits annulus, prevents that valve rod is blown out to the valve body outside in the loosening back of filling pressure under the effect of interior media pressure.
Background technique:
Be widely used in the conventional ball valve on the industries such as chemical industry, oil, rock gas, metallurgy, owing to often use, in the long-term impact flow process of medium, valve ball and the distortion of valve base sealing surface abrasion, the filler of valve rod is loosening easily, produce and reveal, the valve that must upgrade in time influences normal safe operation, otherwise, easily breaking out of fire and explosive accident, befouling environment, consequence is serious, product is short working life, cause and delay work, maintenance, installation bring many unnecessary troubles to the user, bring massive losses to the user.
The model utility content:
At the deficiency of above-mentioned ball valve, the utility model provides a kind of novel fire prevention ball valve, by low lid, pad, spring, valve seat, split annulus, valve body, valve gap etc. and form.
The technological scheme that its technical problem that solves the utility model adopts is: upper valve rod major part and valve body contacting point are provided with two and split annulus; The valve seat fabricated structure, valve seat inserted valve seat support the inside, the sealing of valve seat support and trim ring pads existing with graphite grazing, and the equally distributed spring in trim ring bottom is pushed valve seat to spheroid; Valve is the two-piece flanged connecting structure.
The beneficial effects of the utility model are: good airproof performance, and heat dissipation rate is fast, wear-resistant, and is corrosion-resistant, long service life, fire safety makes things convenient for user installation and use.
