Abstract
The utility model relates to a top assembly type integral inclined surface metal sealing ball valve. The valve body is an integral outer casing, the interior cavity of the valve body is provided with a ball body, a valve rod is arranged on a middle hole on the upper part of a valve cover, and an inverted sealing cushion is arranged between the valve rod and the valve cover. The upper end of the valve rod is connected with a driving device, and the lower end is provided with a compression spring which is connected with the ball body. Filler is filled in the middle hole of the valve core. A liner ring and a compressing nut are arranged on the upper part of the filler. An end surface cushion is arranged on the end surfaces of the valve cover and the valve body. Metal valve seats are respectively arranged between the double inclined surfaces of the valve body and the ball body. A winding type sealing cushion is embedded into a bottom groove of the metal valve seat. A sealing pair formed by the ball body and the metal valve seat is sprayed with tungsten carbide or nickel base alloy and ions to nitridize.

Description
Technical field
The utility model relates to a kind of ball valve, especially a kind of dress formula integral ramp metal seal ball valve of going up.
Background technique
Existing metal seal ball valve usually adopt left and right valve body split type to a minute ball valve, it is side-mounted that ball valve mostly is greatly, it is big exist to open and close moment, because of the temperature difference and piping erection stress influence have increased keying moment greatly or caused leakage, thereby has shortened the working life of ball valve greatly.
Summary of the invention
The purpose of this utility model just provides a kind of double inclined plane formula sealing surface, the sealing between self regulating valve seat and valve body, the spheroid, can 425 ℃ with interiorly anti-ly wash away, high temperature resistant, sealing is reliable, the ball valve of long service life.
The utility model realizes that the technological scheme that above-mentioned purpose adopted is: valve body is a monolithic case, body cavity is provided with spheroid, valve rod is located on the mesopore on valve gap top, be provided with the back seal pad between valve rod and the valve gap, the valve rod upper end connects with drive unit, the valve rod lower end is provided with pressure spring and connects with spheroid, the mesopore of valve gap is provided with filler, be provided with lining ring and gland nut above the filler, valve gap and valve body end face are provided with end washers, be respectively equipped with metal seat valve between the double inclined plane of described valve body and the spheroid, the metal seat valve bottom groove is embedded in the wrap style sealing gasket, formed sealing pair sprayed wc of spheroid and metal seat valve or nickel-base alloy, plasma nitrided.
Described drive unit can be manual operating device or worm gearing, pneumatic actuating device, electric performance device.
The spheroid runner through-bore axis of the present utility model and the centre of sphere are eccentric, spheroid forms the inclined-plane, spheroid and two seal valve seats are packed into together and are processed in advance in the valve body on inclined-plane, press down spheroid by two inclined-planes on the valve body with the elastic thrust that is enclosed within the pressure spring in the valve rod and reach sealing effect.Double inclined plane formula sealing surface of the present utility model, when spheroid and valve seat, valve body and the prooving of valve seat, the gap that is produced is compensated automatically by the elastic thrust of pressure spring, sealing between self regulating valve seat and valve body, valve seat and the spheroid, have anti-ly wash away, high temperature resistant, reliable sealing characteristics, opening and closing number of times increases more than 1 times, working life is longer 1.5 times than ordinary ball valve, when the online replacing ball valve of needs component, do not need ball valve is pulled down from pipeline, can repair or replace component as long as unload bottom flange, make maintenance more convenient.
