Abstract
The utility model discloses a double-eccentric V-shaped adjusting ball valve, which is characterized in that a transmission device is connected at the top of a valve body as well as a valve shaft therein, a valve seat in the valve body is connected with a ball by an adjusting screw, a sealing ring is arranged on the valve body, the central line of the V-shaped ball has a deflection angle with the central line of the valve body, and a sealing pair is deviated from the central line of the valve shaft. In the invention, double eccentricity, the V-shaped ball and the adjustable structure are adopted, so that the circulation area of a pipeline is enlarged, the equal percentage flow characteristics are approached, the weight of the ball is one third of that of the existing ball, and the sealing pair is adjustable, so that the double-eccentric V-shaped adjusting ball valve is especially suitable for valves containing fiber solids or slurry medium for partition or adjusting flow.
Description
Technical field
The utility model relates to a kind of ball valve, particularly relates to a kind of two eccentric V-type and regulates ball valve.
Background technique
Being widely used in industries such as electric power, metallurgy, oil, chemical industry, environmental protection, medicine, food makes to cut off medium or regulates the ball valve that flow is used, its spheroid is a single piece, its valve seal sealing seat is symmetry fully, when valve opens and closes in the process, friction is arranged between valve seals and the spheroid all the time, seal ring is worn and causes valve leak, its valve seal poor performance.Valve that leaks or replacing seal ring or replacing valve.Like this, will inevitably increase user's economic burden.
The model utility content
The purpose of this utility model provides a kind of two eccentric V-type and regulates ball valve, and it is that a kind of sealability is reliable, and valve easy to adjust, energy-conservation.
The technological scheme that the utility model solution prior art deficiency is taked is: the utility model comprises transmission device, valve body, spheroid, valve seat, valve shaft, seal ring, transmission device is connected in the top of valve body, and link to each other with valve shaft in the valve body, spheroid is connected on the valve shaft, and valve seat and links to each other with spheroid bottom in valve body, seal ring is on valve body, its spheroid is a V-type, ball centre line and valve body center line drift angle, sealing pair and valve shaft disalignment.Valve seat is connected by adjusting screw with valve body.
The beneficial effects of the utility model are:
1, the utility model has adopted the structure of two off-centre, during Open valve, spheroid and valve body is thrown off rapidly, and during closure, its sealing pair is in conjunction with tight, and sealing does not have leakage.
2, the utility model has been eliminated the error that produces because of processing and installation etc. by the sealing of adjusting screw regulating valve seat and spheroid, and good airproof performance does not produce jam.
3, spheroid of the present utility model is a V-type, is about 1/3 of existing pipeline ball-valve spheroid, and it not only has the characteristic of ball valve, possesses gate valve simultaneously, the advantage of butterfly valve, and the Flow-rate adjustment characteristic is good, and its Flow characteristics is approximate equal percentage.
4, the utility model circulation area is big, and flow resistance coefficient is little, and the pressure loss is little.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model structure plan view.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As shown in Figure 1, 2, transmission device 1 is installed in the top of valve body 7 and is connected with the top of valve shaft 2 in the valve body 7, valve body 7 passes through filler 3 with valve shaft 2, bearing 4 connects, spheroid 5 is a V-type, spheroid 5 is in valve body 7, the top of spheroid 5 links to each other with valve shaft 2, valve seat 6 in bottom and the valve body 7 links to each other, seal ring 8 is between valve body 7 and valve seat 6, and valve seat 6 is connected with spheroid 5 usefulness adjusting screw 10, the sealing of its adjusting screw 10 can regulate valve seats 6 and spheroid 5, spheroid 5 center line B and valve body 7 center line A drift angles, sealing pair C and valve shaft center line D skew.
