Abstract
The utility model relates to a high-temp. and high-pressure resistant whole hard sealing ball valve, comprising an outlet end, an inlet end and a control end. Primarily, the control end is composed of an inner rotating shaft, a convex sleeve, a convex sleeve for the inner rotating shaft, and a keying pin, which are assembled into a whole and the whole is installed in the hole cavity of an outer rotating shaft. The convex sleeve is fixedly connected with the outer rotating shaft. The inner end face of the outer rotating shaft is provided with a ball and a taper sleeve. The outer rotating shaft is screwed tightly by a hexagon socket head cap screw. The outer shaft and a sealing gasket are installed in the hole cavity of an inner central sleeve. A shaft bearing is fixed by a screw nut. A positioning cover is fixed with an outer central sleeve by a hexagon bolt. The outer end of the outer rotating shaft is provided with a handle. The utility model has the advantages of compact structure, high temp. and high pressure resistance, easy operation, and opening and closing quickness, being widely suitable for industries, such as petroleum industry, chemical industry, electric force industry, etc.
Description
The utility model relates to a kind of fully hard Sealing ball-valve of high temperature high voltage resistant that applies in oil, chemical industry, the power industry.
Present employed ball valve can only be suitable for normal temperature, low pressure (2kg/cm
2) open and close down, when ducted fluid temperature (F.T.) with pressure is higher than normal temperature and pressure is higher than 2kg/cm
2When above, produce hot affinity, open and close slowly, the operation effort, easy to wear and corrosion causes leakage, and stability in use is poor, can't install and use in high temperature high-pressure fluid medium pipelines such as oil, chemical industry, electric power.
The purpose of this utility model provides the fully hard Sealing ball-valve of a kind of high temperature high voltage resistant, and it can be at high temperature (250 ℃, high pressure (310kg/cm
2Keep excellent sealing performance under the operating conditions, operate light, open and close rapidly, wear-and corrosion-resistant, wide, the good stability of using scope are good gate valve and the stop valves in the high-temperature, high pressure fluid medium pipeline.
The purpose of this utility model is achieved in that the fully hard Sealing ball-valve of a kind of high temperature high voltage resistant, comprise outlet end, entry end and control end three parts constitute, outlet end is by spheroid is housed in the valve body, main supporting sleeve, spacer and seal body, sealing sleeve, sealing gasket, end cap is tightened fixing by bolt, entry end is by secondary supporting sleeve, spacer, seal body, secondary sealing sleeve, secondary stage clip, sealing gasket and end cap are tightened fixing through bolt, it mainly is that control end is by interior rotating shaft, protruding cover, recessed cover of interior rotating shaft and key pin are assembled into one, pack in the outer shaft vestibule, protruding cover and outer shaft are affixed firmly, prevent to become flexible, the outer shaft interior edge face is equipped with ball, tapered sleeve and rotating shaft are tightened through bolt, overlap in the vestibule in outer shaft and sealing gasket are packed into, bearing is fixed by nut, location lid is fixed through bolt and outer middle cover screwing, and handle is equipped with in the outer shaft outer end.Whole ball valve adopts cemented carbide to make and seals, spheroid adopts Stainless Steel Alloy, can bear High Temperature High Pressure, the control manipulatable end adopts the spiral pulling to convert the change of tapering to, by the inner conical drogue vary in diameter, make the degree displacement of ball valve closing center produce new center, make and seal the surface at the spheroid of condition of high voltage and cemented carbide and contact and begin disengaging, and obtain small leakage, produced spheroid and seal between lubricated, overcome the hot affinity of under high-temperature and high-pressure conditions, rotating, made ball valve open and close rotate easily, reach and open and close purpose rapidly.
The utility model compact structure, reasonable in design, adopt fully hard airtightly, can bear the operating conditions of High Temperature High Pressure and overcome hot affinity, wear-and corrosion-resistant, operation easily opens and closes rapidly, is widely used in industries such as oil, chemical industry, electric power.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
As shown in Figure 1, the fully hard Sealing ball-valve of a kind of high temperature high voltage resistant, comprise outlet end, entry end and control end three parts constitute, outlet end is by spheroid (6) is housed in the valve body (7), main supporting sleeve (5), spacer (3) and seal body (4), sealing sleeve (2), sealing gasket (10) and end cap (1) are tightened fixing through bolt (11), entry end is by secondary supporting sleeve (8), spacer (3), seal body (4), secondary sealing sleeve (26), secondary stage clip (9), sealing gasket (10) and end cap (1) are tightened fixing through bolt (11), it mainly is that control end is by interior rotating shaft (15), protruding cover (16), recessed cover of interior rotating shaft (19) and key pin (22) are assembled into one, pack in outer shaft (21) vestibule, protruding cover (16) is affixed firmly with outer shaft (21), prevent to become flexible, outer shaft (21) interior edge face is equipped with ball (30), tapered sleeve (13,12), ball (31) and rotating shaft (14) are tightened through hexagon socket head cap screw (27), overlap in (28) vestibule in outer shaft (21) is packed into sealing gasket (29), bearing (23) is fixing by nut (18), location lid (17) through hex head bolt (25) with outer in overlap (24) and tighten fixingly, handle (20) is equipped with in outer shaft (21) outer end.Working procedure is by shaking handgrip (20), drive outer shaft (21), protruding cover (16), the recessed cover of interior rotating shaft (19) carries out screw drives, impel interior rotating shaft (15) laterally to move, by tapered sleeve (12,13) produce dilating of diameter, under the top of main supporting sleeve (5) power effect influence, make spheroid (6) be subjected to the high pressure effect to begin to start, reaction force makes handle (20) produce torque force, owing to be subjected to the influence of protruding cover (16) spiral and interior rotating shaft (15) displacement, make spheroid (6) break away from seal body (4), spheroid (6) begins to rotate, and torsion disappears, and the spheroid (6) of the opening ball valve face that dams is promptly opened valve.Anti-thus crank handle (20), closed ball (6) face that dams is a throttle down gradually.
