A plurality of circular water tanks are formed in the valve element body, the circular water tanks are distributed in a lamination mode and are connected through connecting water tanks, the circular water tanks and the connecting water tanks are sealed to form the cooling channels, supporting shafts extending towards the two sides of the valve element body are arranged on the valve element body, the water inlet channel is arranged in one supporting shaft extending towards one side, the water outlet channel is arranged in the other supporting shaft extending towards the other side, the water inlet channel is connected with the cooling channels through the first connecting channel, and the water outlet channel is connected with the cooling channels through the second connecting channel. The valve element is high in cooling efficiency and capable of effectively guaranteeing the service life of the sealing piece.
Description
Technical field
The utility model relates to a kind of spool, particularly a kind of ball valve core.
Background technique
Ball valve is used for transmission and the circulation of control media, is widely used in the industries such as electric power, mine, metallurgy, chemical industry.The quality of sealing effect can directly affect quality and the working life of valve between ball valve and the valve seat.
For some occasions very high to seal request, mostly guarantee sealing by the silicone rubber O-ring pressed spool that is fixed on the valve seat.Ordinary rubber seal ring heatproof is below 200 ℃, if excess Temperature, seal ring is easy to lose efficacy.
If ball valve uses under hot environment (800 ℃), as spool not being cooled off, the spool temperature can rise and reach on the seal ring very soon, causes seal ring to damage, thereby causes ball valve to use.Therefore, for the ball valve that the high temperature occasion is used, extremely important to the spool cooling, the quality of spool cooling effect also can directly affect whole equipment using effect.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of ball valve core of energy effective cooling.
The utility model provides a kind of spool, it comprises: the spool body, intake tunnel, the first connecting passage, the cooling channel, the second connecting passage and exhalant canal, be provided with a plurality of annular tanks on the described spool body, described annular tank lamination distributes, connect by connection water channel between the described annular tank, the sealed formation of described annular tank and connection water channel cooling channel, described spool body is provided with the back shaft that extends to both sides, wherein in the back shaft of side extension, be provided with intake tunnel, in the back shaft of opposite side extension, be provided with exhalant canal, described intake tunnel is connected by the first connecting passage with described cooling channel, and described exhalant canal is connected by the second connecting passage with described cooling channel.
Described annular tank and connection water channel form described cooling channel by the steel plate sealing.
Described the first connecting passage is connected with undermost annular tank, and described the second connecting passage is connected with the annular tank of the superiors.
Described spool also includes inner cylindrical shell, and described inner cylindrical shell is welded on the inside of described spool body.
Spool of the present utility model, simple in structure, cooling effectiveness is high, can prolong the working life of Sealing.
Description of drawings
Below in conjunction with accompanying drawing the technical solution of the utility model is described in detail, so that characteristic of the present utility model and advantage are more obvious.
Figure 1 shows that an embodiment's of the utility model spool schematic diagram.
Figure 2 shows that the B-B generalized section.
Embodiment
Be illustrated in figure 1 as an embodiment's of the utility model spool schematic diagram.Figure 2 shows that the B-B generalized section.Ball valve core includes spool body 1, intake tunnel 5, the first connecting passage 3, cooling channel 2, the second connecting passage 4, exhalant canal 6 and inner cylindrical shell 7.Spool body 1 is generally casting, is provided with annular tank 10 on the spool body 1.Annular tank 10 laminations distribute, and connect by connection water channel 12 between the annular tank 10.In one embodiment, annular tank 10 and connection water channel 12 are with spool body 1 casting.Annular tank 10 and connection water channel 12 soldered sealings form cooling channel 2.In one embodiment, annular tank 10 becomes the cooling channel with connection water channel 12 by steel plate 11 welded seals.Spool body 1 is provided with the back shaft 8 and 9 that extends to both sides, wherein is provided with intake tunnel 5 in the back shaft 8 of side extension, is provided with exhalant canal 6 in the back shaft 9 of opposite side extension.Intake tunnel 5 is connected by the first connecting passage 3 with cooling channel 2, and exhalant canal 6 is connected by the second connecting passage 4 with cooling channel 2.In one embodiment, the first connecting passage 3 and the second connecting passage 4 form in the welding of spool body by steel plate.Inner cylindrical shell 7 is welded on the inside of spool body 1, and high temperature media flows through in the cylindrical shell 7 internally.In one embodiment, after cooling channel 2, the first connecting passage 3 and 4 welding of the second connecting passage were finished, inner cylindrical shell 7 was welded to connect with the spool body.
Cooling water flow through successively intake tunnel 5, the first connecting passage 3, cooling channel 2, the second connecting passage 4 and exhalant canal 6 rear outflows.Cooling water successively flow to the superiors' annular tank 10 from orlop annular tank 10 in cooling channel 2 in one embodiment.
Spool major advantage in the utility model is:
1, enclosed water-cooling structure reduces foreign matter to the pollution of cooling water;
2, at spool inwall boiling water groove, increase heat exchange area; The area of passage of appropriate design tank guarantees that enough 3, water velocity can be taken away heat as early as possible, avoids occurring cavitation erosion;
4, tank and the direct casting of spool body, only the tank opening seals with Plate Welding, has reduced weld seam leakage point and welding job amount;
5, ringwise stacked distribution of water channel, all linked with one another, cooling water enters next anchor ring by the passage between the adjacent anchor ring and begins circulation after an anchor ring has circulated;
6, cooling water enters the orlop anchor ring from spool one side shaft hole by airtight passage, circulates along every layer of anchor ring from bottom to top, flows out from the opposite side axis hole by closed channel behind the superiors' anchor ring of flowing through;
7, inner/outer tube is made split-type structural, makes things convenient for the processing of internal cooling water flow passage.
