Abstract
The utility model provides a high-temperature high-pressure ball valve, which comprises a valve body, a valve cap, a ball, an upper valve stem, a lower valve stem, a valve seat and a hard alloy seal ring, wherein the ball is mounted in an inner cavity of the valve body, the hard alloy seal ring is arranged on the valve seat via surfacing welding, the valve cover is mounted on the valve body, the valve seat is disposed on two sides of the inner cavity of the valve body, a metal corrugated pipe is arranged between the back of the valve seat and the valve body, and the metal corrugated pipe, the valve seat and the valve body are connected via welding. The ball, the upper valve stem and the lower valve stem are integrated, a sliding bearing is mounted between the upper valve steam and the valve cover, and another sliding bearing is mounted between the lower valve stem and the valve body. The high-temperature high-pressure ball valve has the advantages that the ball valve utilizes a top-mounted structure which is convenient and fast in maintenance, utilizes the metal corrugated pipe to seal, increases high temperature resistance, eliminates leakage points of the valve seat and the valve body, has large expansion and increases sealing reliability.
Description
Technical field
The utility model relates to a kind of ball valve, especially is a kind of High Temperature High Pressure ball valve.
Background technique
At present at the high-pressure ball valve that uses in metallurgy, petrochemical industry, nuclear power field, generally adopt three stage structure, promptly valve gap respectively is equipped with in the valve body both sides, is connected by bolt and nut between valve body and the valve gap, valve must be pulled down from pipeline when overhauling.In addition, the initial sealing of seal ring and spheroid is to lean on the pretightening force of the spring at valve seat back to realize that need take containment measures between valve seat and the valve body, resistance to high temperature is poor.
Summary of the invention
Adopt three stage structure in order to overcome existing high-pressure ball valve, time-consuming during maintenance, and have leakage point between valve seat and valve body, and the deficiency of resistance to high temperature difference, the utility model provides a kind of High Temperature High Pressure ball valve.
The technological scheme that its technical problem that solves the utility model adopts is a kind of High Temperature High Pressure ball valve, comprise valve body, valve gap, spheroid, upper valve rod, lower valve rod, valve seat, cemented carbide seal ring, spheroid is installed in body cavity, the built-up welding of cemented carbide seal ring is on valve seat, valve gap is installed on the valve body, body cavity two sides are equipped with valve seat, also have a metal bellows between the back of valve seat and the valve body, between metal bellows and valve seat and the valve body respectively by being welded to connect.
Spheroid and upper valve rod, lower valve rod are an integral body, between upper valve rod and the valve gap sliding bearing are housed, and between lower valve rod and the valve body sliding bearing are housed.
The beneficial effects of the utility model are to have adopted last dress formula structure, and are easy to maintenance quick, adopt the wavy metal seal of tube, improved heat-resisting quantity, eliminated the leakage point of valve seat and valve body, and extending amount is big, has improved sealing reliability.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the tectonic maps of present embodiment;
Among the figure: 1. upper valve rod; 2. valve gap; 3. valve body; 4. valve seat; 5. cemented carbide seal ring; 6. metal bellows; 7. spheroid; 8. lower valve rod; 9. sliding bearing.
Embodiment
As shown in Figure 1, a kind of High Temperature High Pressure ball valve, comprise valve body 3, valve gap 2, spheroid 7, upper valve rod 1, lower valve rod 8, valve seat 4, cemented carbide seal ring 5, spheroid 7 is installed in the inner chamber of valve body 3,5 built-up welding of cemented carbide seal ring are on valve seat 4, and valve gap 2 is installed on the valve body 3, and inner chamber two sides of valve body 3 are equipped with valve seat 4, also have a metal bellows 6 between the back of valve seat 4 and the valve body 3, between metal bellows 6 and valve seat 4 and the valve body 3 respectively by being welded to connect.Adopt metal bellows 6 as the sealing between valve seat 4 and the valve body 3, medium power effect area is big, and extending amount is big, has improved the resistance to high temperature of valve, and sealing is reliable.
Valve gap 2 is installed on the valve body 3, and valve seat 4, spheroid 7 all can be packed into from the top of valve body 3, does not need during maintenance valve is pulled down from pipeline, only need open valve gap 2, and spheroid 7 is taken out and can overhaul easily.
