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 dress cryogenic ball valve, by valve body, the connection chamber being located at runner on valve body and connecting passage, is provided with spheroid in connection chamber, and valve body is provided with the actuator that the valve rod that links with spheroid and actuate valve stem rotate.Be provided with valve seat between runner and spheroid, the axial two ends due to this type of valve flowing channel all can be used as media inlet end and medium outflow end, higher for the sealing requirements between valve seat and spheroid.Usual meeting is located at Sealing respectively in the both lateral sides of valve seat; wherein the Sealing of one end and spheroid are implemented to seal; the Sealing of the other end and valve body are implemented to seal; but valve flowing channel axial two ends medium is when entering or export; valve seat easily leaks with the Sealing at valve body place, the sealing of valve body cannot be protected.
Summary of the invention
For the deficiency that prior art exists, the utility model provides a kind of good airproof performance, structure upper dress cryogenic ball valve simple, easy for installation.
For achieving the above object, the utility model provides following technological scheme: one fills cryogenic ball valve, include valve body, be located at the connection chamber of runner on valve body and connecting passage, spheroid is provided with in connection chamber, valve body is provided with the actuator that the valve rod that links with spheroid and actuate valve stem rotate, valve seat is provided with between runner and spheroid, valve seat includes sealing front end and sealing rear end, sealing gasket is provided with between its sealing front end and spheroid, Sealing is provided with between sealing rear end and valve body, it is characterized in that: between the sealing rear end of described valve seat and valve body, offer slipper seal chamber, being provided with in this slipper seal chamber can valve base sealing cushion block along slipper seal chamber toward polyslip, Compress Spring is provided with between this valve base sealing cushion block and valve seat, valve base sealing cushion block relative to Compress Spring conflict one end the other end be provided with can with the sealing gasket of its conflict, the both lateral sides end face of sealing gasket respectively with valve body and valve base sealing rear end gluing, sealing, have to conflict between described valve base sealing cushion block and the inconsistent end face of sealing gasket and expand gap.
Adopt technique scheme, by the Compress Spring arranging axial one end and valve seat is conflicted, the other end and valve base sealing cushion block are conflicted in slipper seal chamber, and valve base sealing cushion block relative to Compress Spring conflict one end the other end arrange with can with the sealing gasket of its conflict, sealing gasket impels the sealing in slipper seal chamber, after arranging like this, no matter the pressure of medium is entered by the front portion of valve seat or rear portion, sealing gasket all can realize sealing, and the setting in expansion gap of conflicting makes the sealing effect of sealing gasket better.
The utility model is set to further: the triangular shape ramp projections that valve base sealing cushion block towards the end face of sealing gasket is, sealing gasket is provided with and the triangular shape groove with triangular shape ramp projections adaptation on valve base sealing cushion block, and described conflict expansion gap is the gap between triangular shape ramp projections and triangular shape groove.
Adopt technique scheme, it is simple that structure is set like this, good sealing effect, the triangular shape ramp projections of valve base sealing cushion block and the conflict of sealing gasket triangular shape groove, make the sealing between the horizontal side arm of sealing gasket and valve body and valve seat more tight, thus improve sealing effect.
The utility model is further set to: sealing gasket offers with triangular shape groove in the triangular shape vallecular cavity be oppositely arranged relative to the conflict the other end place of one end of valve base sealing cushion block.
Adopt technique scheme, when pressure medium is entered by the rear portion of valve seat, pressure medium enters in the triangular shape vallecular cavity of sealing gasket, makes two lateral sidewalls of sealing gasket and valve body and valve seat gluing, sealing closely, ensure that sealing effect.
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
As Fig. 1, one shown in Fig. 2 fills cryogenic ball valve, include valve body 1, be located at the connection chamber 12 of runner 11 on valve body 1 and connecting passage 11, spheroid 2 is provided with in connection chamber 12, valve body 1 is provided with the actuator 4 that the valve rod 3 that links with spheroid 2 and actuate valve stem 3 rotate, this actuator 4 can be handwheel, also can be motor, valve seat 5 is provided with between runner 11 and spheroid 2, valve seat 5 includes sealing front end 51 and sealing rear end 52, sealing gasket 6 is provided with between its sealing front end 51 and spheroid 2, Sealing is provided with between sealing rear end 52 and valve body 1, slipper seal chamber 7 is offered between the sealing rear end 52 of valve seat 5 and valve body 1, being provided with in this slipper seal chamber 7 can valve base sealing cushion block 53 along slipper seal chamber 7 toward polyslip, Compress Spring 71 is provided with between this valve base sealing cushion block 53 and valve seat 5, valve base sealing cushion block 53 relative to Compress Spring 71 conflict one end the other end be provided with can with the sealing gasket 8 of its conflict, the both lateral sides end face of sealing gasket 8 seals rear end 52 gluing, sealing with valve body 1 and valve seat 5 respectively, have to conflict between valve base sealing cushion block 53 and the inconsistent end face of sealing gasket 8 and expand gap 81.In such scheme, by the Compress Spring 71 arranging axial one end and valve seat 5 is conflicted, the other end and valve base sealing cushion block 53 are conflicted in slipper seal chamber 7, and valve base sealing cushion block 53 relative to Compress Spring 71 conflict one end the other end arrange with can with the sealing gasket 8 of its conflict, sealing gasket 8 impels the sealing in slipper seal chamber 7, after arranging like this, no matter the pressure of medium is entered by the front portion of valve seat 5 or rear portion, sealing gasket 8 all can realize sealing, and the setting in expansion gap 81 of conflicting makes the sealing effect of sealing gasket 8 better.
