Abstract

A high-temperature and high-pressure forged steel ball valve comprises a welding neck flange, an octagonal ring gasket, a valve seat sleeve, a spring, a valve seat bushing, a connecting seat, a lower fixing shaft, a joint bolt and so on, and is manufactured into a fixed full bore structure through forging and hard bidirectional sealing; the valve body is formed by linking up octagonal rings; a valve rod is manufactured to be cone-shaped; the stub end of the valve rod is arranged in a cavity and mounted outwards through an inner chamber in a reversed manner; a protective stuffing box is arranged in the position where the valve rod is arranged; the sealing surface of the ball body and the surface of the valve rod are made of hard chrome plating; a self pressure relief device is arranged in a middle cavity; the lower fixing shaft and a lower valve cap are designed and manufactured to be a whole; an actuating mechanism can be conveniently connected with a pneumatic, electric or hydraulic device to achieve remote monitoring; and a coil spring is arranged at the bottom of the valve seat, so as to reduce attrition and achieve strong sealing. The ball valve can avoid dust accumulation and jamming, can achieve zero leakage, and is appropriate for high flow rate, high temperature and high pressure operation; and the service life is long.

Description

The High Temperature High Pressure forging steel ball valve
Technical field:
The utility model relates to a kind of fluid circuit control gear that can carry various corrosivity particles, liquid medium or regulate flow under High Temperature High Pressure, especially valve body is a forged steel, the sealing surface of spheroid is that the Si Teli cemented carbide is made, and has improved the sealability of valve and has prolonged working life.
Background technique:
Present hard seal ball valve can not solve corrosion-resistant, sealing, thermal expansion is steady, valve rod is firm, dust stratification or problem such as stuck, results in hand cramps or safety problem to the user.
Summary of the invention:
Existing hard seal ball valve, solve corrosion-resistant, sealing, problems such as thermal expansion is steady, valve rod is firm, dust stratification or stuck problem exist deficiency.The utility model provides a kind of High Temperature High Pressure forging steel ball valve, is made up of welding neckflange, octagonal ring pad, valve seat cover, spring, valve seat lining, connecting base, following stationary axle, connecting bolt etc.
The technological scheme that its technical problem that solves the utility model adopts is: make fixed, all-pass gauge structure with the forging two-way hard seal, valve body is connected with octagonal ring, and valve rod is made taper, and stub end is by putting in the chamber, by the outside upside-down mounting of inner chamber; The valve rod place is provided with the safety type sealed letter, and sealing surface, the stem surface of spheroid are made with hard chromium plating; Lumen is provided with from pressure relief device, and following stationary axle and bottom flange are made integral body; Actuator can realize remote monitoring with pneumatic, electronic, the convenient connection of Hydraulic actuator; The valve seat bottom is provided with helical spring, falls friction, forms sealing by force.
The beneficial effects of the utility model are: being in operation is not subjected to medium influence, dust stratification or stuck phenomenon can not occur, easy to operate, and opening process zero is revealed, and is easy to maintenance, increases the service life.
Description of drawings:
Fig. 1 is product structure figure.
Among the figure, 1, welding neckflange 2, octagonal ring pad 3, valve seat cover 4, spring 5, valve seat lining 6, valve seat 7, spheroid 8, connecting base 9, valve rod 10, insurance sealed letter 11, valve body 12, stationary axle 13, connecting bolt down
Embodiment:
Directly design with forging two-way hard seal, stationary structure, all-pass, dust stratification or stuck phenomenon can not occur.Valve rod 9 is designed to taper, and stub end is by putting in the chamber, by the outside upside-down mounting of inner chamber, reaches and bears various pressure and valve rod 9 is broken away from; Be connected with octagonal ring pad 2, valve rod 9 places are provided with insurance sealed letter 10, strengthen valve rod 9 steadinesss; Make with hard chromium plating on the sealing surface of spheroid 7, valve rod 9 surfaces, strengthens working life and corrosion-resistant; The lumen design guarantees that from pressure relief device chamber pressure is normal; Following stationary axle 12 is designed to an integral body with bottom flange, thereby reduces stationary axle 12 and middle body matching gap down; Operating mechanism can be with pneumatic, and electronic, the convenient connection of Hydraulic actuator realized remote monitoring; Valve seat 6 bottoms are provided with helical spring 4, and friction and valve seat 6 sealing surface wears reach the thrust sealing purpose when reducing valve opening and closing.
