Abstract
The utility model relates to a trunnion ball valve capable of being opened and closed easily. The trunnion ball valve comprises a drive device 1, a valve cover 3, a valve body 5, a valve seat 10, attached bodies 12, a valve rod 13 and a ball body 17. The trunnion ball valve is characterized in that two short shafts 16 are arranged at bodies at the upper and lower ends of the ball body 17, a rolling bearing 8 and a supporting plate 7 which are used for supporting the ball body 17 are respectively arranged on each short shaft 16, the supporting plates 7 are fixed on the attached bodies 12 by virtue of round pins 6, and the ball body 17 is supported in a cavity formed by the valve body 5 and the attached bodies by virtue of the short shafts 16, the rolling bearings 8 and the supporting plates 7. The trunnion ball valve has the advantages that the operating torque for opening or closing the trunnion ball valve is small, and thus the trunnion ball valve is labor-saving and convenient to operate; and as the short shafts, the rolling bearings and the supporting plates for supporting the ball body are arranged in the closed cavity, and sealing pieces are arranged on the two sides of the rolling bearings, the corrosion from internal harmful media is effectively isolated, the pollution from an external environment is avoided, and the trunnion ball valve is protected from inside to outside, thereby more reliably guaranteeing the safe operation of the ball valve.
Description
Technical field
The utility model relates to the fixing ball valve of the valve that a kind of oil pipeline is used, particularly a kind of light opening and closing.
Background technique
Fixing ball valve all is to adopt the slip self oiling bearing to come supporting sephere at present, and its supporting structure is an external bracing.So-called external bracing is to offer an axis hole in the bottom of spheroid and valve body, in their axis hole, is provided with stationary axle, is assemblied on the valve body with bolt, nut and Sealing at the bottom of valve body design end cap to seal.Its shortcoming, the one, this structure has increased the leakage point of ball valve, has reduced safety coefficient.The 2nd, because support force acts on the valve body, the support arm of force that extended because the form and position tolerance and the tolerance of size that in manufacture process, occur make spheroid under the effect of pressure medium, can produce bigger displacement, causes that ball valve moment of torsion in switching process is excessive simultaneously.Bring certain difficulty to operation.
Sliding bearing supports, and friction factor is big, and the opening and closing moment of torsion of valve is very big; Ten minutes difficulty, particularly heavy caliber, high pressure fixing ball valve, this shortcoming is particularly outstanding; Be that present fixing ball valve is in evolution; Perplex the difficult problem of valve manufacturing firm always, up to this point fail to solve, limited the application of fixing ball valve on fluid-transporting tubing.
Summary of the invention
The utility model technical barrier to be solved is, overcomes the excessive deficiency of above-mentioned opening and closing torque force, and a kind of fixing ball valve of light opening and closing is provided.
The technical solution of the utility model is, comprises drive unit 1, valve gap 3, valve body 5, valve seat 10, attaches body 12, valve rod 13 and spheroid 17, and spheroid 17 is located in the valve body 5, attaches body 12 and is located at the two side ends of valve body 5 and fixing with it by bolt 15 respectively; Valve seat 10 is located at spheroid 17 and is attached between the body 12, and is pressed on the spheroid 17 by spring 11; One end of valve rod 13 and the upper end of spheroid 17 link, and the other end and drive unit 1 link; Valve gap 3 is located at the outside of valve rod 13 and is fixed on the valve body 5; The body at spheroid two ends about in the of 17 is provided with minor axis 16, and spheroid 17 and two minor axises 16 thereof all are arranged at valve body 5 and attach in the cavity that body 12 constitutes; Be respectively equipped with the rolling bearing 8 and dunnage 7 of supporting sephere 17 on two minor axises 16 up and down of spheroid 17, dunnage 7 is fixedly connected on attaches on the body 12.
Be respectively equipped with Sealing 9 on the minor axis 16 of rolling bearing 8 both sides or on the dunnage 7.
Dunnage 7 is a rectangular, and dunnage 7 is fixed on through straight pin 6 attaches on the body 12.
The advantage that the utility model and existing technology compare and possessed; The one, the two ends of spheroid 17 adopt rolling bearing 8 to support, and the operation moment of torsion when greatly reducing the On/Off valve is little, more laborsaving; More convenient, particularly more outstanding to high pressure, bigbore fixing ball valve; The 2nd, spheroid 17 adopts the inner support design; Make the minor axis 16 and the rolling bearing 8 of supporting sephere 17 increase protection together again, avoided the pollution of external environment condition, shortened the support arm of force simultaneously; Assembly relation and form and position tolerance that in manufacture process, produces and tolerance of size have been reduced; Make spheroid less at pressure medium effect bottom offset, the operation moment of torsion is little, and it is also just lighter, laborsaving to operate; The 3rd, the both sides of rolling bearing are respectively equipped with Sealing 9, and hazardous medium and rolling bearing 8 are separated, and have strengthened the protection to rolling bearing 8, guarantee the safe operation of valve, have improved working life.
