Description
Technical field
This utility model is related to a kind of valve valve cage attaching/detaching apparatus, fills more particularly, to a kind of dismounting of nuclear power station valve valve cage
Put.
Background technology
Valve quantity at present with valve cage (stream cover) in nuclear power plant technique system is more, and it is heavier to be used in mostly nuclear island
In the system wanted, coordinate between valve cage and valve body closely, particularly after equipment on-line certain hour, in equipment disintegration process
In, dismounting can be more difficult, typically adopts copper rod or plastic hammer to be tapped and rapping, is allowed to loosening and is drawn off, have
When, also heating can be carried out to valve body with fire weldering and be drawn off, can so cause one to be, in percussion, rapping process, easily to make standby
Part is caused to deform and is damaged, and two is, in rapping process is tapped, to easily cause debris in valve pocket, form foreign body, cause valve
Badge is puckery or foreign body pad causes the internal hemorrhage due to trauma of valve on faying face, three be during taking-up, usually because the hand strength at two ends not
Unanimously, cause valve cage embracing on valve body tightly, and correctly can not install, meanwhile, during taking-up, also easily because
Valve cage comes off to cause to run over and injure and staff or causes the generation of device damage accident.Four be the increase in labor intensity and maintenance when
Between.
Utility model content
The purpose of this utility model is exactly to provide a kind of nuclear power station valve to overcome the defect of above-mentioned prior art presence
Gate valve cage attaching/detaching apparatus.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of nuclear power station valve valve cage attaching/detaching apparatus, including hoisting nut, elevator bolt, lifting gripper shoe and support column,
Described elevator bolt one end is connected with valve cage to be dismounted through after lifting gripper shoe, and the other end is connected with hoisting nut, described
Support column be located at lifting gripper shoe and the end face of flange of valve between.
Described elevator bolt is identical with hoisting nut quantity, is two.
The external screw thread of described elevator bolt is matched with the female thread of valve cage to be dismounted.
Described elevator bolt is full thread steel screw rod.
Described lifting gripper shoe is disc-shaped structure, and which is provided with four and supports stud bolt hole and two elevator bolt holes,
Described support stud bolt hole is connected with support column, and described elevator bolt hole is connected with elevator bolt.
Described four support stud bolt hole to be located on same circumference.
Two described bolts are connected and are located on same circumference.
Described support column is provided with four, is step structure.
Compared with prior art, this utility model has advantages below：
1) it is safe efficient, valve cage will not be damaged using this utility model device, foreign body will not be produced.
2) cheap using material price, processing technique is simple, and reliability is high.
3) it is easy to operate, can Reusability, the lifting to valve cage can be completed by precession hoisting nut, such that it is able to pacify
Entirely, efficiently pull down valve cage.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein 1 is hoisting nut, 2 is elevator bolt, 3 is lifting gripper shoe, 4 is support column, 5 is valve cage, 6 is valve body.
Specific embodiment
This utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with this utility model
Implemented premised on technical scheme, given detailed embodiment and specific operating process, but guarantor of the present utility model
Shield scope is not limited to following embodiments.
A kind of applicable nuclear power station valve valve cage attaching/detaching apparatus of this utility model, the device are mainly made up of four parts：
Hoisting nut 1, elevator bolt 2, lifting gripper shoe 3, support column 4.
Wherein lift gripper shoe 3 to be processed into disc by certain thickness #20 steel plates (size is true by the diameter of valve cage 5
It is fixed), it is machined with 4 and two bolts hole on two circumference of disk respectively, 4 bolts hole of outer ring are used for installing support column
4, two bolts hole of inner ring are for through elevator bolt 2；
Elevator bolt 2 is processed into certain length (length is determined by valve cage lifting capacity) full flight screw, screw thread by #20 rod irons
Diameter is determined by the screw on valve cage end face.
Support column 4 be processed into by #20 rod irons it is symmetrical stepped, in the middle of flange in valve and gripper shoe, length by
Lifting capacity needed for valve cage determines；
Hoisting nut 1 is standard nut, is supported the use with elevator bolt 2.
Using method is as shown in the Combinatorial resolution figure in accompanying drawing：
1. two lift-bolts 2 are screwed in the screw of valve cage end face；
2. support column 4 and lifting gripper shoe 3 are arranged in valve on end face of flange；
3. the lifting to valve cage can be completed by precession hoisting nut 1, valve cage is pulled down such that it is able to safe and efficient.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any those familiar with the art can be readily occurred in various in the technical scope that this utility model is disclosed
Equivalent modification or replacement, these modifications or replacement should all be covered within protection domain of the present utility model.Therefore, this practicality
New protection domain should be defined by scope of the claims.
