Background technique
Ball valve is a kind of activation members, and namely spheroid is driven by valve rod, and around the valve that the axis of valve rod rotates.Be mainly used in blocking or connect the medium in pipeline, also can be used for the regulating and control of fluid.Traditional ball valve forms primarily of the actuator of valve body, valve gap, spheroid, valve rod and actuate valve stem, valve body is provided with medium inlet passage and medium flow pass, expanding channels chamber conducting between medium inlet passage and medium flow pass, spheroid is arranged in connection chamber, medium inlet passage and be provided with seal valve seat between medium flow pass and spheroid.Traditional seal valve seat is mounted in valve body by the connection opening of valve body and valve gap usually, then the spheroid with valve base sealing is being installed, this type of ball valve is higher for the required precision of spheroid and valve seat processing, if add man-hour size to occur deviation, light then spheroid cannot be mounted in valve body, heavy then cause cannot implementing between spheroid and valve seat sealing, valve body cannot normally be used.
Summary of the invention
For the deficiency that prior art exists, the utility model provides a kind of good airproof performance, structure flange mounting type seal ball-valve simple, easy to adjust.
For achieving the above object, the utility model provides following technological scheme: a kind of flange mounting type seal ball-valve, include valve body, valve gap, spheroid, the actuator of valve rod and actuate valve stem, described valve body is provided with medium inlet passage and medium flow pass, by connection chamber conducting between medium inlet passage and medium flow pass, spheroid is arranged in connection chamber, medium inlet passage and be provided with seal valve seat between medium flow pass and spheroid, it is characterized in that: the described seal valve seat being positioned at medium inlet passage includes and extends to medium inlet passage and be that screw thread spins and the extension set with runner with the inwall of medium inlet passage, axial one end of this extension set is in the inlet of medium inlet passage, the other end extends to spheroid place, extension set extends between the one end at spheroid place and spheroid and is provided with Sealing, described spheroid is provided with inserting groove, valve rod and spheroid one end of linking is provided with the grafting block with this inserting groove adaptation, the sidewall of grafting block transverse direction offers mounting hole, the inserting groove sidewall being provided with one end and spheroid in mounting hole is conflicted, the spring buffer part that the bottom end face of the other end and mounting hole is conflicted.
Adopt technique scheme, by arranging extension set in medium inlet passage, and seal valve seat and extension set are wholely set, in installation process, first spheroid can be installed, then at installation extension set, and the spacing between adjustable extension set and spheroid, and meet the sealing between spheroid and seal valve seat, not only good airproof performance, and too high requirement is not had to the machining accuracy of spheroid and seal valve seat, thus reduce cost of production; Between valve rod and spheroid, the setting of resilient snubber then makes to have elastic buffer power between spheroid and valve rod, impels the better tightness between spheroid and seal valve seat.
The utility model is set to further: the cross section of the runner of extension set assumes diamond in shape, and each inwall of runner is respectively the arcuation inwall towards indent in the middle part of runner; Described resilient snubber is damping spring.
Adopt above-mentioned technology case; the cross section of runner assumes diamond in shape; and each inwall of runner is respectively towards the arcuation inwall of indent in the middle part of runner; after arranging like this; the inwall of runner has cutting function, when there is less particle in medium, due to the effect of pressure medium; this particle can be shredded by the inwall of runner, in order to avoid it accumulates in spheroid the pressure or pollution spheroid that have influence on valve body.
The utility model is further set to: the inlet that valve body is positioned at medium inlet passage is provided with adjustable extension set locking framework, and this extension set locking framework includes the clamping block that is fixedly connected with valve body and is that screw thread spins and the adjusting screw rod can conflicted with extension set with clamping block.
Adopt technique scheme, the setting of extension set locking framework can implement locking to it after extension set is installed and regulated, prevent the screw thread between extension set and medium inlet passage from occurring skid and cause the mounting point of extension set to be subjected to displacement, ensure that the sealing of valve body.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the I portion enlarged diagram of Fig. 1;
Fig. 3 is the II portion enlarged diagram of Fig. 1;
Fig. 4 is the structural representation of extension set during the utility model is implemented.
Embodiment
A kind of flange mounting type seal ball-valve as shown in Fig. 1-Fig. 4, include valve body 1, valve gap 2, spheroid 3, the actuator 5 of valve rod 4 and actuate valve stem 4, this actuator 5 can be motor, also can be handwheel, valve body 1 is provided with medium inlet passage 11 and medium flow pass 12, by connection chamber 13 conducting between medium inlet passage 11 and medium flow pass 12, spheroid 3 is arranged in connection chamber 13, medium inlet passage 11 and be provided with seal valve seat 6 between medium flow pass 12 and spheroid 3, the seal valve seat 6 being positioned at medium inlet passage 11 includes and extends to medium inlet passage 11 and be that screw thread spins and the extension set 61 with runner 62 with the inwall of medium inlet passage 11, axial one end of this extension set 61 is in the inlet of medium inlet passage 11, the other end extends to spheroid 3 place, extension set 61 extends between the one end at spheroid 3 place and spheroid 3 and is provided with Sealing 7, the seal 7 is sealing gasket, spheroid 3 is provided with inserting groove 31, valve rod 4 and spheroid 3 one end of linking is provided with the grafting block 41 with this inserting groove 31 adaptation, the sidewall of grafting block 41 transverse direction offers mounting hole 411, inserting groove 31 sidewall being provided with one end and spheroid in mounting hole 411 is conflicted, the spring buffer part 8 that the bottom end face of the other end and mounting hole 411 is conflicted, this resilient snubber 8 is damping spring, also can be spring sheet.In such scheme, by arranging extension set 51 in medium inlet passage 11, and seal valve seat 6 and extension set 61 are wholely set, and in installation process, can first install spheroid 3, then at installation extension set 61, and the spacing between adjustable extension set 61 and spheroid 3, and meet the sealing between spheroid 3 and seal valve seat 6, not only good airproof performance, and too high requirement is not had to the machining accuracy of spheroid 3 and seal valve seat 6, thus reduce cost of production; Between valve rod 4 and spheroid 3, the setting of resilient snubber 8 then makes to have elastic buffer power between spheroid 3 and valve rod 4, impels the better tightness between spheroid 3 and seal valve seat 6.
