The ball valve is convenient to use, capable of achieving online maintaining effects and is long in service life.
Description
Technical field
The utility model relates to a kind of ball valve.
Background technique
Ball valve, generally include valve body, valve rod, valve gap and spheroid that two ends are provided with medium runner, traditional ball valve, the valve seat that coordinates with spheroid of its setting adopts spring to support, in the ball valve switch process, spring imposes active force to valve seat all the time is affixed valve seat and ball seal, makes spheroid and valve seat have all the time larger force of sliding friction, thereby causes valve seat and spheroid serious wear, so that ball valve is not high working life, and is difficult for on-line maintenance.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of ball valve, is comprised of valve body, spheroid, valve rod, valve rod, operating device etc.
the technological scheme that its technical problem that solves the utility model adopts is: two medium channels that are provided with valve pocket in valve body and are arranged on the valve pocket two ends, spheroid is arranged in valve pocket, corresponding each medium channel of valve pocket place is provided with two valve seats that match with spheroid, valve body is provided with the opening that supplies spheroid and valve seat to pass, opening is provided with valve gap, valve gap and valve body are and removably connect, valve seat is set to soft valve seat, spheroid is the eccentric structure setting, and spheroid with the front end diagonal of the closing sense of rotation perpendicular tangent plane of its rotating shaft less than the rear end diagonal, two valve seats are closed the setting of sense of rotation lopsidedness to spheroid respectively, be provided with on spheroid to the dunnage of top, both sides pressure valve seat, the corresponding valve seat of valve body position is provided with stiffening rib, spheroid is provided with upper and lower back shaft, and dunnage is provided with two, and dunnage is the round-meshed rectangle setting of center tool, and dunnage can be located on upper and lower back shaft by relatively upper and lower back shaft rotating sleeve.
The utility model beneficial effect: valve seat is firm, simple in structure, easy to use, the effect of on-line maintenance, long service life.

In figure, 1, valve body, 101, the matter passage, 102, stiffening rib, 2, spheroid, 201, the lower support axle, 3, valve rod, 4, operating device, 5, valve seat, 6, dunnage, 601, circular hole, 7, valve gap.
Embodiment
as shown in drawings, the disclosed a kind of ball valve of the utility model, comprise valve body 1, spheroid 2, the operating device 4 of valve rod 3 and valve rod 3, two medium channels 101 that are provided with valve pocket in described valve body 1 and are arranged on the valve pocket two ends, described spheroid 2 is arranged in valve pocket, corresponding each medium channel of described valve pocket 101 places are provided with two valve seats 5 that match with spheroid 2, described valve body 1 is provided with the opening that passes for spheroid 2 and valve seat 5, opening is provided with valve gap 7, described valve gap 7 is with valve body 1 and removably connects, described valve seat 5 is set to soft valve seat, described spheroid 2 is the eccentric structure setting, and spheroid 2 with the front end diagonal L 1 of the closing sense of rotation perpendicular tangent plane of its rotating shaft less than rear end diagonal L 2, described two valve seats 5 are closed the setting of sense of rotation lopsidedness to spheroid 2 respectively.By adopting technique scheme, spheroid 2 is in closing process, Fig. 2, Fig. 3 clockwise direction are the closing direction of spheroid 2, early stage is with not contact of valve seat 5, until spheroid 2 just contacts with valve seat 5 when closing, at this moment, only need a little spinning ball 2 again, due to the eccentric structure of spheroid 2 and being obliquely installed of valve seat 5, spheroid 2 just can further compress with valve seat 5 and reach sealing, thereby spheroid 2 is closed medium channel 101 fully; And spheroid 2 is contactless with valve seat 5 under opening state, and valve seat 5 is soft valve seat, during maintenance, can open 7 pairs of spheroids of valve gap 2 and carry out dismounting with valve seat 5, thereby have the effect that facilitates on-line maintenance.
The present embodiment further arranges: be provided with to the dunnage 6 of top, both sides pressure valve seat 5 on described spheroid 2.Under opening state, or spheroid 2 is in closing process due to spheroid 2, and early stage is with not contact of valve seat 5, the easy disengaging configuration of valve seat 5, and by the employing technique scheme, 6 pairs of valve seats 5 of dunnage support, and make firm being positioned in valve body 1 of valve seat 5.
The present embodiment further arranges: described spheroid 2 is provided with upper and lower back shaft 201, described dunnage 6 is provided with two, described dunnage 6 is the rectangle setting that the center has circular hole 601, and described dunnage 6 can be located on upper and lower back shaft 201 by relatively upper and lower back shaft 201 rotating sleeves.By adopting technique scheme, dunnage 6 two ends compress valve seat 5, make valve seat 5 more firm in valve body 1.
The present embodiment further arranges: the corresponding valve seat of described valve body 15 positions are provided with stiffening rib 102.By adopting technique scheme, due to the eccentric structure of spheroid 2 and being obliquely installed of valve seat 5, spheroid 2 produces outward pressure when further compressing with valve seat 5, and the corresponding valve seat of valve body 15 positions arrange stiffening rib 102, thereby improve the working life of valve body 1.
