Abstract
The utility model provides a reinforced ball valve which comprises a ball valve body, a valve core arranged in the body, a handle arranged on the valve core and a ball valve core spindle seal ring arranged between the handle and the valve core. The reinforced ball valve is characterized in that the ball valve core spindle seal ring is arranged on an opening portion of the lower end of the contact end of the handle and the valve core, and integrated with the ball valve core spindle by injection molding, so that the round seal ring and the main body are injection molded together, and therefore a good seal effect and low torque force are achieved.
Description
Technical field
The utility model relates to the ball valve field, particularly relates to a kind of ball valve with Novel sealing ring.
Background technique
At present traditional ball valve production technology is first ball valve core, valve core seal ring to be placed in the mould after the molding and forming, assemble again the valve core shaft seal ring and press handle, manufacturing efficiency is low, and as shown in Figure 1, and its sealing means is to seal by the handle compresses seal, sealing is relatively poor, the mode of this assembling requires the amount of compression of O RunddichtringO larger, so that ball valve is in turning process, torsion is larger, affects working life and the sealing thereof of ball valve.
The model utility content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of good airproof performance is provided, the reinforced ball valve of high life.
For solving the problems of the technologies described above, the technical solution of the utility model is as follows:
A kind of reinforced ball valve main body, be arranged at spool in the main body, be arranged between handle on the spool and handle and the spool and be provided with ball valve core rotating shaft sealing circle, wherein, described ball valve core rotating shaft sealing circle is arranged at the lower ending opening place of described handle and spool contact jaw, described ball valve core rotating shaft sealing circle and the integrated molding and forming of described valve core shaft.
Compared with prior art, the utility model has the advantage of:
The utility model is by being enclosed within circular seal ring on the valve core shaft in the process of injection-molded body, so that circular seal ring with the main body molding and forming, reaches lower torsion thereby reach better sealing effect.
Description of drawings
Fig. 1 is the structural drawing of prior art;
Fig. 2 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with specific embodiment.
As shown in Figure 2, the utility model provides a kind of reinforced ball valve, described ball valve is by ball valve main body 4, the ball valve core 3 of ball valve main body 4 interior settings, be socketed with the handle 1 for rotating operation on the spool 3, be provided with seal ring between handle 1 and the ball valve core 3, described seal ring is ball valve core rotating shaft sealing circle 2, described ball valve core rotating shaft sealing circle 2 is arranged at the lower ending opening place of the contact jaw of described handle 1 and spool 3, described ball valve core rotating shaft sealing circle 2 is complementary with the shape of valve core shaft, be arranged in the rotating shaft of spool, with existing after injecting the ball valve main body, be loaded on seal ring, the mode seal ring that then presses this assembling that handle seals is different, the rotating shaft sealing of ball valve core described in the utility model circle 2 is by being socketed in seal ring in spool 3 rotating shafts in the process of injection moulding ball valve main body, because described ball valve core rotating shaft sealing circle 2 is just to be socketed on the valve core shaft when injection-molded body 4 is finished, by in injection moulding, being inserted in seal ring, carry out again injection moulding, so that seal ring is with main body 4 molding and forming, main body 4 and seal ring are become one structure, thereby reach better sealing effect and lower torsion.
