Description
Technical field
The utility model relates to a kind of ball valve, particularly a kind of upper-mounting type ball valve.
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.
Upper-mounting type ball valve is widely used on oil and natural gas pipeline, can be used in oil recovery, chemical industry, chemical fibre, metallurgy, electric power and papermaking apparatus.Traditional upper-mounting type ball valve is divided into floating ball valve and fixing ball valve, the spacing in floating ball valve between adjustable spheroid and valve seat, and the sealing between spheroid and valve seat is protected.But current regulative mode implements to regulate to the position of spheroid, not only operates inconvenience, and be not easy to correct, be not easy to return back to original position after spheroid regulates.
Summary of the invention
For the deficiency that prior art exists, the utility model provides a kind of easy to adjust, simple upper-mounting type ball valve of structure.
For achieving the above object, the utility model provides following technological scheme: a kind of upper-mounting type ball valve, include valve body, medium inlet passage on valve body is set, the connection chamber of medium flow pass and connecting media inlet passage and medium flow pass, spheroid is provided with in connection chamber, valve body is provided with and extends in connection chamber and the valve rod be connected with spheroid, valve rod is provided with actuator relative to the other end being connected one end with spheroid, medium inlet passage and be provided with valve seat between medium flow pass and spheroid, Sealing is provided with between valve seat and spheroid, it is characterized in that: described valve seat is provided with adjustable valve seat towards spheroid toward the trimming assembly of polyslip, this trimming assembly includes the contiguous block that is fixedly arranged on outside valve seat and is the adjustment seat that screw thread spins with contiguous block, the bounding means that puts in place can conflicted with adjustment seat is provided with in connection chamber.
Adopt technique scheme, by arranging contiguous block on valve seat, then in the outer sheathed adjustment seat spun with its screw thread of contiguous block, when rotating adjustment seat, adjustment seat and contiguous block are relative movement, contiguous block then can drive between valve seat and spheroid and implement slippage, with the laminating degree between this regulating valve seat and spheroid, the sealability between spheroid and valve seat is guaranteed.The setting of bounding means of putting in place is then for implementing relative positioning effect to adjustment seat, when adjustment seat is conflicted with the bounding means that puts in place, adjustment seat can rotate in a circumferential direction, but its axial position be on contiguous block can not be subjected to displacement, when now rotating adjustment seat, contiguous block can be just relative movement with adjustment seat, meets the slippage of valve seat with this.
The utility model is set to further: contiguous block is fixedly connected with valve seat by clamping bolt, and the described bounding means that puts in place includes and is set up in connection chamber and the rolling bearing can conflicted with adjustment seat.
Adopt technique scheme, it is simple that structure is set like this, processing and easy for installation, the bounding means that puts in place selects rolling bearing to be because the frictional force between rolling bearing and adjustment seat is little, rotating in a circumferential direction of adjustment seat can not be had influence on when adjustment seat and rolling bearing are fitted, namely can not have influence on the normal regulating of valve seat.
The utility model is further set to: valve seat includes and the front sealing end of ball seal and the rear seal end that is connected with front sealing end, be provided with sealing gasket between front sealing end and spheroid, between rear seal end and valve body, be provided with at least two-stage seal ring.
Adopt technique scheme, sealing is set like this and is guaranteed.
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.
Embodiment
A kind of upper-mounting type ball valve as shown in Figure 1 and Figure 2, include valve body 1, the connection chamber 13 of the medium inlet passage 11 arranged on valve body 1, medium flow pass 12 and connecting media inlet passage 11 and medium flow pass 12, spheroid 2 is provided with in connection chamber 13, valve body 1 is provided with and extends in connection chamber 13 and the valve rod 3 be connected with spheroid 2, and valve rod 3 is provided with actuator 4 relative to the other end being connected one end with spheroid 2.Actuator 4 is for driving handwheel or drive motor, medium inlet passage 11 and be provided with valve seat 5 between medium flow pass 12 and spheroid 2, Sealing 6 is provided with between valve seat 5 and spheroid 2, valve seat 5 is provided with the trimming assembly 7 of adjustable valve seat 5 towards spheroid 2 toward polyslip, this trimming assembly 7 includes the contiguous block 71 be fixedly arranged on outside valve seat 5 and the adjustment seat 72 spun in screw thread with contiguous block 71, is provided with the bounding means 8 that puts in place can conflicted with adjustment seat 72 in connection chamber 13.In such scheme, by arranging contiguous block 71 on valve seat 1, then in the outer sheathed adjustment seat 72 spun with its screw thread of contiguous block 71, when rotating adjustment seat 72, adjustment seat 72 and contiguous block 71 are in relative movement, contiguous block 71 can drive between valve seat 5 and spheroid 2 and implement slippage, with the laminating degree between this regulating valve seat 5 and spheroid 2, the sealability between spheroid 2 and valve seat 5 is guaranteed.The setting of bounding means 8 of putting in place is then for implementing relative positioning effect to adjustment seat 72, when adjustment seat 72 is conflicted with the bounding means 8 that puts in place, adjustment seat 72 can rotate in a circumferential direction, but its axial position be on contiguous block 71 can not be subjected to displacement, when now rotating adjustment seat 72, contiguous block 71 just with adjustment seat 72 in relative movement, can meet the slippage of valve seat 5 with this.And the setting of the bounding means 8 that puts in place can be convenient to valve body 1 and valve seat 5 and spheroid 2 can be implemented dismounting on line and replacing when being in and line working.
In the utility model embodiment, contiguous block 71 is fixedly connected with valve seat 5 by clamping bolt 711, and arrange structure so simple, certainly, contiguous block 71 can, with valve seat 5 by being welded to connect, also be also feasible.The bounding means 8 that puts in place in the utility model embodiment includes and is set up in connection chamber 13 and the rolling bearing can conflicted with adjustment seat 72.The bounding means 8 that puts in place selects rolling bearing to be because the frictional force between rolling bearing and adjustment seat 72 is little, can not have influence on rotating in a circumferential direction of adjustment seat 72, namely can not have influence on the normal regulating of valve seat 5 when adjustment seat 72 is fitted with rolling bearing.Certainly, it should be noted that, the bounding means 8 that puts in place also can be roller, is also feasible.
In order to improve the sealability between valve seat 5 and valve body and spheroid 2, valve seat 5 in the utility model embodiment includes the front sealing end 51 sealed with spheroid 2 and the rear seal end 52 be connected with front sealing end 51, be provided with sealing gasket between front sealing end 51 and spheroid 2, between rear seal end 52 and valve body 1, be provided with at least two-stage seal ring.
