Abstract
The utility model relates to a ball-shaped butterfly valve. When the utility model is opened, a pressure relief mechanism sealed by a connecting rod and an auxiliary valve seat is opened first; thereby, the differential pressure between the front and the back parts of the valve is reduced, and the opening torque of the valve is reduced. A driving mechanism which rotates a butterfly plate is in a rail type driving structure so as to obtain simplicity and lightness. In addition, the utility model is also provided with integration type pneumatic and manual executive devices so that the utility model also has the advantage of convenient operation.
Description
The utility model relates to a kind of butterfly valve that is used on the flowing medium pipeline.
The present Ball type butlerfly valve that uses must drive butterfly plate and rotate and realize valve opening during use.When pressure reduction before and after the valve was big, the unlatching moment that the rotation butterfly plate needs was very big, and the driving mechanism that rotates butterfly plate designs simple inadequately lightly for sufficient intensity is arranged.And the present manual actuating device inconvenient operation of using of separated type.
The utility model is will overcome deficiency that prior art exists to design a kind of unlatching moment little, and drive mechanism is simply light, is provided with the Ball type butlerfly valve of the easy to operate manual actuating device of integral type gas.
The utility model comprises valve body, butterfly plate, valve rod and valve rod driving device.The auxiliary-seat that is located on the butterfly plate is sealed and matched in valve pocket one side and horizontal connecting rod one end, is with the connection positioning disk on this connecting rod.The axis of rolling that the connecting rod the other end is provided with and conversion block are provided with, and the oblique angle guide groove is movable cooperates, and conversion block is connected with valve rod longitudinally.
The utility model reduces valve front and back pressure reduction owing to can discharge medium by auxiliary-seat before opening, and the required unlatching moment of rotation butterfly plate is little, and the driving mechanism that therefore rotates butterfly plate also can be simply light.
Further illustrate the utility model below in conjunction with description of drawings embodiment.
Fig. 1 is the utility model embodiment's a plan view;
Fig. 2 is the I portion enlarged view of Fig. 1;
Fig. 3 is the II portion enlarged view of Fig. 1;
Fig. 4 is the A-A profile of Fig. 1.

Pneumatic rail mounted Ball type butlerfly valve as shown in Figure 1, valve body 1 have sealing surface and butterfly plate 18 to cooperate.The auxiliary-seat 21 that is positioned on the butterfly plate 18 is sealed and matched at an end of valve pocket one side and connecting rod 19, be with on the connecting rod 19 and connect positioning disk 20, connecting rod 19 the other ends are provided with 49 movable cooperations of oblique angle guide groove on the axis of rolling 17 and the conversion block 16, conversion block 16 and longitudinally valve rod 9 be connected.The driving mechanism that drives the butterfly plate rotation can adopt similar structure such as gear rack axle, and present embodiment adopts by the roller bolt in the plug screw 14 that is fixed on the valve body 1 13 and is located at the rail mounted driving mechanism that spiral rail slot 48 matches and forms on the valve rod 9.Such structure is quite simply light, makes the rotation of valve rod 9 that track more accurately be arranged.The top of valve rod 9 is connected on the piston of pneumatic actuating device 11, and pneumatic actuating device 11 tops have the manual actuating device 12 of hand-wheel-type gear-box to be connected by the rack shaft 31 that is provided with and the piston of pneumatic actuating device 11, form the manual actuating device of integral type gas.Manually actuating device 12 also can adopt other forms such as screw type, the more laborsaving convenience of operation when adopting the hand-wheel-type gear box structure manual, and it is also more accurate to locate.
The working procedure of present embodiment is:
During unlatching, pneumatic actuating device 11 moves up valve rod 9, cooperates through the oblique angle guide groove 49 on the conversion block 16 and the axis of rolling 17, and pulling connecting rod 19 shrinks to the center, breaks away from and being sealed and matched of auxiliary-seat 21, and medium is therefrom discharged, the pressure reduction on the minimizing butterfly plate 18.Connecting rod 19 is continued, and pulling is shunk and drive butterfly plate 18 by connecting positioning disk 20, butterfly plate 18 and valve body 1 is broken away from compress sealing.Valve rod 9 continues to move up, rail slot 48 and roller bolt 13 roll cooperate under, valve rod 9 is rotated counterclockwise along track, and drives butterfly plates 18 by dive key 15 and butterfly plate fulcrum 3 and be rotated counterclockwise 90 °, the valve complete opening.During valve closing, process is opposite.Valve rod 9 is moved downward, and drives butterfly plate 18 along track and turns clockwise 90 °, valve closes but malcompression sealing.It is overhanging that valve rod 9 continues to move down drivening rod 19, and connecting rod 19 overhanging sealings with auxiliary-seat are pressed on butterfly plate 18 on the sealing surface of valve body 1 by being connected positioning disk 20 simultaneously, and valve is closed fully.Stop the supple of gas or steam when manual, advance hand wheel shaft 41 and gearwheel 33 engagements, rotate handwheel 47, gear 33 is driven by hand wheel shaft 41 and by key 34 turning gear wheel shafts 32.Gear shaft 32 moves up and down rack shaft 31 by the spatial vertical engagement.Rack shaft 31 is connected on the piston of pneumatic actuating device 11, therefore can actuate valve stem come control valve.
