Description
Technical field
The content of present invention belongs to valve opening and adjusts field, and in particular to one kind is fixed for diaphragm type control valve opening
Tooling.
Background technology
By taking the adjusting of nuclear power station main pump lubricating oil as an example, core main pump is called the heart of reactor, and reliability service is for core
The safety of power plant and the influence of economy are self-evident.Main pump motor lubricating oil pipe regulating valve uses diaphragm valve.However, in master
Find that the valve rod is excessively flexible in the operational process of pump motor, vibrated after completing valve opening and adjusting due to pumping ontology,
Valve medium the influences such as washes away and valve opening is caused to change, and then influences the distribution of pump group bearing oil, gives equipment safety operation
Bring threat.In main pump operational process, if the valve opening becomes smaller, causes bearing lubrication insufficient, there is bearing oil starvation to burn
Risk；If valve opening becomes larger, lubricating oil is caused to overflow, pollution pump ontology reduces pump group oil loading amount, or even cause fire
Deng potential risk is very big.Therefore, it is badly in need of a kind of novel tooling solution problems.
Invention content
It is an object of the invention to：A kind of valve fixing tool is provided, using the fixed plate with hatching knurling, increases handwheel
With the frictional force of fixed plate, to be maintained at during main pump is on active service, valve opening is constant, it is ensured that main pump is reliable for operation.
Technical scheme is as follows：One kind being used for the fixed tooling of diaphragm type control valve opening, including one rectangular
The fixed plate B of the fixed plate A of shape, two strips, two U-shaped lead screws and location nut；The U-shaped lead screw, according to oil pipe
Diameter bend is made, and U-shaped lead screw is equipped with screw thread, is matched with location nut；
In use, two U-shaped lead screws are separately mounted to the both sides up and down of diaphragm type regulating valve, one end of each U-shaped lead screw
Two location nuts are put on, two fixed plate B are installed on the U-shaped lead screw of valve handle bottom；It is U-shaped at the top of valve handle
Mounting plate A on lead screw, outside are fixed with location nut.
The fixed plate A, uses thickness for the tablet of 3-8mm.
The one side being in contact at the top of fixed plate A and valve handle is handled with hatching knurling, to increase fixed plate A and valve
Frictional force between at the top of door handwheel.
The fixed plate B uses 2 pieces of thickness for the tablet of 3-8mm.
It is handled with hatching knurling in the one side that fixed plate B is touched with valve handle bottom connection, to increase fixed plate B and valve
Frictional force between door handwheel bottom.
Fixed plate A, fixed plate B, U-shaped lead screw and the location nut is stainless steel.
When installation, add copper sheet to avoid the U-shaped lead screw of stainless steel and the oil pipe of carbon steel because of length between U-shaped lead screw and oil pipe
Phase contacts and potentiometric chemical corrosion occurs.
A kind of application method for the fixed tooling of diaphragm type control valve opening as described in the present invention, including following step
Suddenly：
1) after main pump normal operation, by valve regulated to target flow；
2) above-mentioned fixing bracket is installed, pays attention to avoiding encountering valve handle in installation process, changes valve opening；
3) location nut is uniformly fastened after completing installation, torque 8Nm, and suitable screw thread is coated in location nut
The agent that locks carries out screw retention.
The remarkable result of the present invention is：After the fixing device, the flow of the oil inlet pipe of main pump does not become again
Change, no exceptions, aperture keeps stablizing, 2 heap year of pump group stable operation, to which the peace of main pump and reactor be effectively ensured
Entirely.The present invention, which fixes presurized water reactor main pump lubrication fuel tap, has reference.

Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment is to of the present invention a kind of fixed for diaphragm type control valve opening
Tooling is described in further detail.
As shown in Figure 1, a kind of being used for the fixed tooling of diaphragm type control valve opening, including a rectangular fixed plate
The fixed plate B1 of A3, two strips, two U-shaped lead screws 4 and location nut 2；The U-shaped lead screw 4, it is curved according to tubing diameter
Song is made, and U-shaped lead screw 4 is equipped with screw thread, is matched with location nut 2；
In use, two U-shaped lead screws 4 are separately mounted to the both sides up and down of diaphragm type regulating valve 5, the one of each U-shaped lead screw 4
Two location nuts 2 in end cap install two fixed plate B1 on the U-shaped lead screw 4 of 6 bottom of valve handle；It is pushed up in valve handle 6
