Abstract
The invention provides a direct buried type all-welded insulation ball valve. The direct buried type all-welded insulation ball valve comprises a valve body with a fluid passageway in internal part, a ball body placed at the center of the fluid passageway, a valve rod connected with the upper end of the ball body and a handle connected to the upper end of the valve rod. The direct buried type all-welded insulation ball valve is characterized in that the valve body sequentially comprises a seamless steel tube layer, an insulation layer and a plastic board layer from inner part to outer part, wherein the insulation layer is provided with at least one detection line to connect with a leakage alarming device; a valve base is arranged at the periphery of the ball body, and a valve base support and a spring supporting the valve support are arranged in the valve base; and the valve rod is an extension bar, and the distance of the valve rod extending the valve body is not less than the buried depth of the valve body. The direct buried type all-welded insulation ball valve has the advantages of being flexible to open and close, long in service life, and better in sealing effect under the action of pressure fluid; and the ball valve is provided with an extension valve rod, so that the opening and closing device is in earth surface, the valves can be conveniently opened and closed, the mounting period is shortened, the cost is reduced, and the maintenance is convenient.
Description
Technical field
The invention belongs to valve field, especially relate to a kind of directly buried type and entirely weld Thermal insulating ball valve.
Background technique
The Thermal insulating ball valve that uses at present connects Thermal insulating ball valve as flange substantially, and be to adopt interlayer hot fluid conduction heat compensation to be incubated mostly, in transmission course, need to set up a fluid heater on each thermal insulation valve limit and guarantee to carry out heat compensation, so just need a large amount of fuel to guarantee heating, this conflicts mutually with the target that the current environment protection reduces carbon emission; Adopt the ball valve of interlayer hot fluid insulation to need to weld interlayer in manufacturing process, the cost of interlayer welding is larger, and the manufacture cycle is longer; Common valve rod is shorter, builds the underground space that valve opening and closing is used in valve buried needs simultaneously, has increased installation cost and is unfavorable for maintenance and safeguards.
Summary of the invention
The problem to be solved in the present invention provides a kind of directly buried type and entirely welds Thermal insulating ball valve.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of directly buried type welds Thermal insulating ball valve entirely, comprises that inside has the valve body of fluid passage, places the spheroid of fluid passage central authorities, the valve rod that is connected with the spheroid upper end and the handle that connects the valve rod upper end;
Described valve body comprises seamless steel pipe layer, thermal insulation layer and plastic cement flaggy from inside to outside successively, has at least one in the described thermal insulation layer and surveys line connection leakage warning device;
Described spheroid periphery has a valve seat, and described valve seat periphery has the valve seat support, and described valve seat support is by spring supporting and connect a valve gap, and described spheroid bottom is connected with described valve body by stationary axle;
Described valve rod is extension bar, and the distance that described valve rod stretches out valve body is not less than the burying depth of described valve body;
Further, described spheroid is steel ball inner with holes;
Further, have successively o type circle and axle sleeve between described valve gap and the described valve rod, a pressing plate is positioned at described axle sleeve top and is bolted on the described valve gap;
Further, described valve stem tip is connected with described handle by turbine, and the described valve rod outside has seamless steel pipe layer, thermal insulation layer and plastic cement flaggy successively;
Further, described valve rod bottom is provided with projection, and described valve rod projection is embedded in the groove that is complementary with described projection on the described spheroid;
Further, have gland, o type circle and hexagon socket head cap screw between described stationary axle and the described valve body;
Further, described thermal insulation layer is the high-density foam layer, and described high-density foam is polyurethane;
Further, described detection line is copper cash, and described copper cash is in described thermal insulation layer, and totally three of described copper cash are distributed in respectively described valve body bottom and both sides.
Advantage and good effect that the present invention has are: owing to adopt technique scheme, the foam-filled parcel mode of interlayer has reduced heat compensation website midway in a large number with respect to interlayer hot fluid conduction heat compensation mode, both save construction cost and also saved operation cost, also reduced carbon emission; On internal structure, the present invention adopts spring supporting stent valve stand structure, has reduced rubbing of spheroid and seal ring and has examined coefficient, have open and close flexibly, the life-span is long and in the characteristics of the effect lower seal better effects if of pressure fluid; At valve extension bar is installed, is made start-stop device be in the earth's surface, made things convenient for the keying of valve, need not to build the underground space that valve opening and closing is used, the reduction of erection time, reduce cost, be convenient to maintenance.

Embodiment
As shown in Figure 1, the invention provides a kind of directly buried type and entirely weld Thermal insulating ball valve, comprise that inside has the valve body 1 of fluid passage, places the inside of fluid passage central authorities Stainless Steel Ball 2 with holes, the valve rod 3 that is connected with the Stainless Steel Ball upper end and connect handle 4 on the valve rod, valve body comprises seamless steel pipe layer, foam polyurethane layer 5 and plastic cement flaggy from inside to outside successively, has three copper cash 6 in the polyurethane foam 5 and connects leakage warning device; The Stainless Steel Ball periphery has a valve seat 7, and valve seat 7 peripheries have valve seat support 9, and described valve seat support 9 is supported by spring 8 and connects a valve gap 10, and Stainless Steel Ball 2 bottoms are connected with described valve body by stationary axle; Valve rod 3 is extension bar, and the distance that valve rod stretches out valve body is not less than the burying depth of described valve body; Have successively o type circle and axle sleeve 11 between valve gap 10 and the described valve rod 3, one pressing plate is positioned at described axle sleeve 11 tops and is bolted on described valve gap 10 upper valve rod tops and is connected with described handle by turbine, and the described valve rod outside has seamless steel pipe layer, polyurethane foam and plastic cement flaggy successively; Described valve rod bottom is provided with projection, and described valve rod projection is embedded in the groove that is complementary with described projection on the described spheroid; Have o type circle, gland and hex head bolt between stationary axle and the valve body.
The working procedure of this example: the fluid passage of the through hole of spheroid inside and valve body is perpendicular before opening, the sealing surface of spheroid has stopped the perforation of the fluid passage of valve body, during unlatching, spheroid rotates around the valve body center line, the through hole of spheroid turns to the direction of fluid of valve body gradually under the drive of valve rod, dock fully the final fluid passage of spheroid through hole and valve body of realizing, this enforcement this moment is opened fully, in the time will closing present embodiment, the backward rotation handle, spheroid rotates under the drive of valve rod, and the through hole of spheroid disconnected with being connected gradually of the fluid passage of valve body, until complete obiteration, the present invention's this moment is fully closed.
