Abstract
The utility model provides a simple and convenient online fixed ball valve of maintenance upper assembling type of changing, is through setting up external adjustable disk seat, and its lantern ring in the middle of through adjusting bolt being outwards moves, and the pretightning force of discharging the spring makes the disk seat move backward, reserves the spheroidal space of assembly, is in open position to the spheroid, puts into the valve body internal stability and reserves the lower valve rod. Good spheroid is fixed to the valve gap that closes, adjust outside bolt make in the middle of the motion of cover hoop spheroid, compression spring makes it produce the pretightning force to the disk seat, reaches initial sealed effect, also can realize the pretightning force size for the regulating action, the fine solution of this structure the difficult characteristics of safeguarding of changing of prior art, do not need what special instrument frock yet.
Description
Technical field
The utility model relates to valve field, is specifically related to a kind of easy online repair and replacement fill formula fixing ball valve.
Background technique
Ball valve uses very extensive in pipe-line system, mainly should be during the feature ball valves such as ball valve has compact structure, and flow resistance is little, and the opening time is short use and keeps away the replacing unavoidably occurring easily damaged parts, and main is exactly the replacing problem of valve seat.Only have upper-mounting type ball valve just to have in existing ball valve online change and to safeguard.But numerous use structures more or less have topical type, and complex structure, not easy to operate.As the valve seat of disposed thread structure, this structure only can be used on the valve of small dimension.Be exactly the destructions such as the corrosion of screw thread in Long-Time Service in addition, in actual maintenance, be difficult to dismounting.
Summary of the invention
In order to solve the deficiencies in the prior art, of the present utility model providing in a kind of easy online repair and replacement fills formula fixing ball valve.
The technical solution that the utility model adopts is: a kind of easy online repair and replacement fill formula fixing ball valve, comprise valve body, valve rod, valve seat and spheroid, described valve body is provided with valve gap, described valve gap is bolted on valve body, described valve body is provided with the shift motion for valve seat movement laterally, also intermediate collar is provided with outside described valve body, described intermediate collar is connected by spring with between valve seat, described intermediate collar is also provided with the fixing device for fixing intermediate collar, outside described intermediate collar, is also provided with creeping flange.
Described fixing device comprises fixing bolt and stop nut, and described intermediate collar is arranged on valve body by fixing bolt, and described stop nut is between intermediate collar and valve body.
Described intermediate collar comprises the assembly department be connected with valve seat, valve body, and the front end that described assembly department is connected with valve seat is provided with mounting groove, and described spring is positioned at mounting groove.
The assembly department of described intermediate collar and the joint of valve body are also provided with O RunddichtringO and carbon seal ring, and described O RunddichtringO quantity is 2.
Described creeping flange comprises the slipping part be connected with intermediate collar, and described slipping part is provided with the slippage stroke for the outside translation of creeping flange, and described creeping flange is arranged in intermediate collar by bolt.
The slipping part of described creeping flange and the joint of intermediate collar are provided with O RunddichtringO and carbon seal ring.
The beneficial effects of the utility model are: the utility model provides in a kind of easy online repair and replacement and fills formula fixing ball valve, by arranging external adjustable valve seat, it is the middle collar outwards movement by adjusting bolt, discharge the pretightening force of spring, valve seat is moved backward, reserve the space of assembling spheroid, spheroid is in enable possition, puts into the good lower valve rod of valve body internal fixtion.The valve gap that closes fixes spheroid, regulate outside bolt that intermediate collar is moved to spheroid, Compress Spring makes it produce pretightening force to valve seat, reach the effect of initial sealing, what also can realize pretightening force size is regulating action, this structure well solves prior art difficulty and changes the feature safeguarded, does not also need what special instrument frock.
