Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of ball valve.
Background technique
One of widely used valve of ball valve, its working principle is the same with stopcock, all is to make valve opening and closing by rotary spool, but lighter than stopcock switch, relative volume is little, can make big-diameter ball valve.Ball valve sealing is reliable, and is simple in structure, easy to maintenance, and sealing surface and the spheroid closed state of being everlasting is difficult for by the medium erosion, thereby is widely used in industries such as oil, chemical industry, metallurgy.
Existing ball valve mainly comprises two kinds of fixing ball valve and floating ball valves.The spheroid of fixing ball valve is fixed, spheroid is provided with supporting axis, bearing is housed on the supporting axis, therefore after being subjected to pressure medium, spheroid does not produce movement, and the valve seat generation is mobile, Sealing is pressed on the spheroid, with the assurance sealing, so the operation moment of torsion of this class ball valve is little, is applicable to high pressure and bigbore valve.
The spheroid of floating ball valve floats, under the effect of pressure medium, spheroid can produce certain displacement and be pressed on the sealing surface of outlet end, guarantee the sealing of ball valve, the good airproof performance of floating ball valve, but spheroid bears the seal ring that the load of working medium has all been passed to outlet end, therefore will consider the work loads of living the spheroid medium that can sealing ring material stand, so floating ball valve generally is only applicable to the occasion of mesolow.
Referring to Fig. 1, shown in 2, fixing ball valve generally comprises valve body 1, valve seat 2, and the spheroid 3 that seals, be provided with spring 4 between valve body 1 and the valve seat 2, in the situation that valve seat 2 can be under pressure again in valve body move left and right, also be provided with O-ring seals 5 between valve body 1 and the valve seat 2, valve seat 2 is generally metal and makes, offer a slot 6 on it, nonmetallic sealed inserted piece 7 of slot 6 interior insertions, when surface and the spheroid close contact of plug-in unit then can be realized sealing, generally also can offer a grease trough 18 on the valve seat, the entrance of grease trough is in the outside of valve seat, and the outlet of grease trough is in the inboard of valve seat near spheroid.The outlet port of grease trough generally is to be designed to a trough with straight angle 19 at present, cause forming between all the other slots a thin-walled 20, because the thickness of thin-walled is very little, cause thin-walled to be easy to fracture, perhaps run-off the straight, so that sealed inserted piece comes off from slot, and then cause the sealing effect of ball valve to descend, ball valve also lost efficacy thereupon.
Summary of the invention
The utility model purpose provides a kind of ball valve, by the improvement to structure, has improved the sealing effect of ball valve.
The technical solution of the utility model is: a kind of ball valve, comprise valve body, valve seat and spheroid, be provided with spring between described valve body and the valve seat, also be provided with O-ring seals between described valve body and the valve seat, offer slot on the described valve seat, cooperate with described slot to be provided with a sealed inserted piece, also offer grease trough on the described valve seat, the outlet port of described grease trough is provided with stiffening rib, consists of a heavy wall between described stiffening rib and described slot.
Further technological scheme, described stiffening rib are a kind of in circular arc or the right angle type.
Further technological scheme, the described stiffening rib outside is not less than the twice of the thickness of described heavy wall to described heavy wall inner distance.
In the technique scheme, described ball valve is by valve body, valve seat and spheroid consist of, be provided with spring and O-ring seals between valve body and the valve seat, offer slot at valve seat, cooperate with slot and to be provided with a sealed inserted piece, on valve seat, also offer grease trough, the entrance of grease trough is opened in the outside of valve seat, near the inboard of spheroid, the outlet port of grease trough is provided with stiffening rib at valve seat in the outlet of grease trough, and this stiffening rib can be a kind of in circular arc or the right angle type, consist of a heavy wall between stiffening rib and slot, the stiffening rib outside is not less than the twice of this thick wall thickness to the distance of heavy wall inboard, so that the walled thickness as compared with the past of heavy wall obviously increases, intensity also is improved, so that heavy wall easy-rupturing not, perhaps run-off the straight, sealed inserted piece are difficult for coming off from slot, and the sealing effect of ball valve also is improved.
The utility model has the advantages that:
1. the utility model is offered stiffening rib by the outlet port at the grease trough of valve seat, consist of heavy wall between stiffening rib and slot, thereby so that not easy-rupturing or inclination of heavy wall avoided sealed inserted piece to come off from slot, sealed inserted piece can contact with spheroid closely, has improved the sealing effect of ball valve;
2. the utility model is simple in structure, and is easy to use, and is easy to realize, is fit to promote the use of.
