In in the bonnet, one end connection valve ball and other end is connected to the valve rod of executing agency, between the valve rod and the bonnet
Provided with being avoided that the guide frame that is damaged during the moment of torsion for producing the executing agency passes to the valve ball.
It is preferred that, the guide frame is set to two, including the first guide frame for being set close to the executing agency and
The second guide frame set close to the valve ball.
It is preferred that, the guide frame is bearing arrangement.
It is preferred that, the bonnet is long neck structure.
It is preferred that, the valve body is bolted to connection with the valve rod.
Technical solutions of the utility model, have the following advantages that：
1. the valve rod dual-guiding structure for the ultralow temperature upper-mounting type ball valve that the utility model is provided, is provided between valve rod and bonnet
It is avoided that the guide frame damaged during the moment of torsion for producing executing agency passes to valve ball；This structure can be protected
Card valve rod only delivers torque to valve ball when transmitting the moment of torsion of executing agency, will not be damaged because of issuable moment of flexure.
2. the valve rod dual-guiding structure for the ultralow temperature upper-mounting type ball valve that the utility model is provided, guide frame is set to two,
Including the first guide frame set close to executing agency and the second guide frame set close to valve ball；This structure can be maximum
The moment of flexure that the reduction valve rod of limit is produced during transmission moment of torsion, valve rod is oriented to knot by the moment of torsion of executing agency first
Moment of torsion is delivered torque into the second guiding mechanism close to one end of executing agency by valve rod in the presence of structure, remake for valve
Ball, further protects valve rod, extends the service life of ball valve.
3. the valve rod dual-guiding structure for the ultralow temperature upper-mounting type ball valve that utility model is provided, bonnet is long neck structure, to protect
Demonstrate,prove stuffing-box position and be in normal temperature state, prevent stuffing-box frosting or icing and influence the normal work of filler.
