Abstract
The utility model discloses a valve structure of an adjusting ball valve. The valve structure comprises a main valve body, an auxiliary valve body, a sealing valve seat, an adjusting valve seat and a spherical valve element. The valve structure is characterized in that the adjusting valve seat is in a spherical shape, the spherical concave face of the adjusting valve seat is matched with the spherical surface of the spherical valve element, and various CV value windows are formed in the spherical concave face. The CV value windows are adopted, and therefore the flow rate of the valve structure can be adjusted as required; the valve structure is simple in structure; meanwhile, the ball valve rotates and stops rotating freely within the range of 0 degree to 90 degrees, the circulating sectional area of the valve seats is changed, and therefore the flow rate of a pipeline is controlled, and the function of adjusting the ball valve is achieved.
Description
Technical field
The utility model relates to a kind of valve body, relate to concretely a kind of spherical valve body and for the adjusting type ball valve valve mechanism of the industry such as chemical industry and light industry.
Background technique
In valve body structure of the prior art, in the industries such as existing chemical industry and light industry, generally there is the equipment that uses ball-cock device; In existing ball-cock device, be mainly used in cutting function, there is no regulating power, existing modulating valve flow resistance is large, negotiability is poor, need to select the adjustment type valve of larger caliber.
Model utility content
In view of there is above problem, the utility model provides a kind of adjusting type ball valve valve mechanism, has within the scope of 0 °～90 ° and rotates arbitrarily and stop, and controls pipeline flow thereby realize valve seat actual internal area size variation, realizes the function that ball valve regulates.
The technical solution of the utility model is: a kind of adjusting type ball valve valve mechanism, comprise major and minor valve body, regulating valve seat, spherical valve core, it is characterized in that: described regulating valve seat is spherical in shape, the spherical concave surface of described regulating valve seat matches with spherical valve core spherome surface, offers various CV value windows on described spherical concave surface.By this structure needs of the existing uninterrupted of cooperate degree (actual internal area) reality of the spherical concave surface of regulation ball valve core and regulating valve seat as required.
Further, described regulating valve seat is fixed on main valve body in the mode press-fiting, and described regulating valve seat end face is provided with inner groovy, between described inner groovy and main valve body, is provided with seal ring.Make installation between regulating valve seat and main valve body easily and guarantee sealing effect by this structure.
Further, described CV value window can require to open arbitrary structures form window according to concrete pipeline flow.This is simple in structure, and can fully realize the accurate adjustment of flow.
Further, described spherical valve core spherome surface can cover CV value window comprehensively.This structure is exactly will guarantee can not pass through by sealing medium in the situation that all stopping as required circulation.
The beneficial effects of the utility model are: the utility model adopts CV value window can regulate as required its flow, and simple in structure, while valve rotates arbitrarily and stops within the scope of 0 °～90 °, thereby realize valve seat actual internal area size variation and control pipeline flow, realize the function that ball valve regulates.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
Fig. 2 is the structural representation that the utility model regulates window
Embodiment
As a kind of mode of execution of the present utility model, as Fig. 1, a kind of adjusting type ball valve valve mechanism shown in 2, comprise master, auxiliary valve body (1, 4), regulating valve seat 2, spherical valve core 3 and other valve annexes, in the diameter of Spherical Volume that described spherical valve core 3 forms between main valve body 1 and auxiliary valve body 4, two valve seats are positioned at main valve body, between auxiliary valve body and ball core coordinate, valve body lumen is formed with the gap between ball core by main valve body and auxiliary valve body, the spherical concave surface of described regulating valve seat is pressed close to ball core spherome surface, on concave surface, open various CV value windows 5, this window is rotated and is regulated window actual internal area size by ball core, to realize the regulatory function of valve.Note: CV value is herein the negotiability representing in valve body, and CV value window is exactly the window that flow can regulate.
In the present embodiment, described regulating valve seat is fixed on main valve body in the mode press-fiting, and described regulating valve seat end face is provided with inner groovy 6, between described inner groovy and main valve body, is provided with seal ring.Make installation between regulating valve seat and main valve body easily and guarantee sealing effect by this structure.
In the present embodiment, described CV value window can require to open arbitrary structures form window according to concrete pipeline flow.This is simple in structure, and can fully realize the accurate adjustment of flow.
In the present embodiment, described spherical valve core spherome surface can cover CV value window comprehensively.This structure is exactly will guarantee can not pass through by sealing medium in the situation that all stopping as required circulation.
The form that adjusting ball valve in the present embodiment is is windowing seat design, mixing valve positioner rotates arbitrarily and stops within the scope of 0 °～90 ° by valve again, thereby realize valve seat actual internal area size variation and control pipeline flow, realize the function that ball valve regulates.
Therefore above a kind of adjusting type ball valve valve mechanism provided by the utility model has been carried out to detailed introduction, applied specific case herein principle of the present utility model and mode of execution are set forth, above embodiment's explanation is just for helping to understand method of the present utility model and core concept thereof; , for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model meanwhile.To be possible to change of the present utility model and improvement, and can not exceed design and the scope that accessory claim can stipulate.
