Background technique
Ball valve is a kind of activation members, is mainly used in blocking or connect the medium in pipeline, also can be used for the regulating and control of fluid.
Industry and the sulfide hydrogen media such as high pressure floating ball valve is applicable to general industry and uses, and is applicable to chemical industry, oil, rock gas, metallurgical, impurity is many, the Gao Long-distance Transmission Pipeline of seriously corroded.Sealing between the valve rod of traditional high pressure floating ball valve and valve body mainly adopts offers ring-type short slot on valve rod, then in ring-type short slot, seal ring is installed, not only make the processing technology of valve rod too complicated, and in the installation process implementing valve rod and valve body, seal ring is easily damaged, valve rod part of the force is in use also inconsistent, makes valve rod easily occur phenomenon that is bending or that break.
Summary of the invention
For the deficiency that prior art exists, the utility model provides a kind of guarantee by force intensity, yielding, not stable high pressure floating ball valve.
For achieving the above object, the utility model provides following technological scheme: a kind of high pressure floating 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 offers the attachment hole with connection chamber conducting, the valve rod be connected with spheroid is provided with in attachment hole, valve rod is provided with actuator relative to the other end being connected one end with spheroid, medium inlet passage and be provided with Sealing between medium flow pass and spheroid, it is characterized in that: being provided with cross section between described attachment hole and connection chamber is step-like ring-type short slot, one end place that described valve rod is connected with spheroid is provided with the step-like contiguous block with ring-type short slot adaptation, bearing is provided with between the bottom of ring-type short slot and the step-like contiguous block of valve rod, be provided with O RunddichtringO between the top of ring-type short slot and the step-like contiguous block of valve rod and compress the elastic pressure parts of O RunddichtringO.
Adopt technique scheme, by the ring-type short slot of setting table scalariform between the attachment hole on valve body and connection chamber, and the step-like contiguous block with this step-like ring-type short slot adaptation is set on valve rod, and O RunddichtringO is set between the top of ring-type short slot and the step-like contiguous block of valve rod, after arranging like this, sealing between valve rod and valve body, without the need to offering mounting groove on valve rod, makes valve rod uniform force, in use can not occur the situation of being out of shape and breaking.And the above-mentioned structure that arranges is simple, easy for installation.The setting of bearing is convenient to valve rod and is in rotating in a circumferential direction in attachment hole, makes the unlatching of valve body and closing process more smooth and easy, there will not be the phenomenon of clamping stagnation.
The utility model is set to further: the auxiliary valve body that valve body includes main valve body and splices with main valve body, medium inlet passage and connection chamber are located on main valve body, medium flow pass is located on auxiliary valve body, be connected by lock bolt between main valve body with auxiliary valve body, and the stitching portion of main valve body and auxiliary valve body is provided with sealing gasket.
Adopt technique scheme, arrange like this and be convenient to install, easy to process, and good airproof performance.
The utility model is further set to: elastic pressure parts is for folding in " U " font elastic pressuring plate.
Adopt technique scheme, it is good that elastic force is set like this, and elastic force not easily disappears.
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, a kind of high pressure floating ball valve shown in Fig. 2, include valve body 1, medium inlet passage 11 on valve body 1 is set, the connection chamber 13 of 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 offers the attachment hole 14 with connection chamber 13 conducting, the valve rod 3 be connected with spheroid 2 is provided with in attachment hole 14, valve rod 3 is provided with actuator 4 relative to the other end being connected one end with spheroid 2, this actuator 4 can be handwheel, also can be motor, medium inlet passage 11 and be provided with Sealing 5 between medium flow pass 12 and spheroid 2, being provided with cross section between attachment hole 14 and connection chamber 13 is step-like ring-type short slot 15, one end place that valve rod 3 is connected with spheroid 2 is provided with the step-like contiguous block 31 with ring-type short slot 15 adaptation, bearing 6 is provided with between the bottom of ring-type short slot 15 and the step-like contiguous block 31 of valve rod 3, be provided with O RunddichtringO 7 between the top of ring-type short slot 15 and the step-like contiguous block 31 of valve rod 3 and compress the elastic pressure parts 8 of O RunddichtringO 7, this elastic pressure parts 8 is for folding in " U " font elastic pressuring plate.Certainly, also can be resilient pressure pad, is also feasible.In such scheme, by the ring-type short slot 15 of setting table scalariform between the attachment hole 14 on valve body 1 and connection chamber 13, and the step-like contiguous block 31 with this step-like ring-type short slot 15 adaptation is set on valve rod 3, and O RunddichtringO 7 is set between the top of ring-type short slot 15 and the step-like contiguous block 31 of valve rod 3, after arranging like this, sealing between valve rod 3 and valve body 1 without the need to offering mounting groove on valve rod 3, make valve rod uniform force, in use can not occur the situation of being out of shape and breaking.And the above-mentioned structure that arranges is simple, easy for installation.The setting of bearing 6 is convenient to valve rod 3 and is in rotating in a circumferential direction in attachment hole 14, makes the unlatching of valve body 1 and closing process more smooth and easy, there will not be the phenomenon of clamping stagnation.
