Background technique
The structure of existing ball valve generally is made up of main valve body, auxiliary valve body, spheroid, valve seat, valve rod, handle and sealing material, and its sealing surface is generally nonmetal, and sealing pair contacts all the time in the open and close process, operational torque is big, sealing pair produces friction, valve non-refractory high pressure, and the life-span is short.
In addition, existing ball valve with pipeline between to be connected be to adopt flange to connect, be provided with seal ring between two flange plate, the ball valve of this structure is in use often because matching gap increases, or Sealing damages and reveals, and in general, the ball valve of revealing or damaging all is that whole changing abandons, the service conduit system is very difficult like this, the maintenance cost height.
The model utility content
For addressing the above problem, the utility model provides a kind of long service life and hoisting capacity very light, existing ball valve all-pass footpath, height, keying are fast, the advantage of two way sealed, have stop valve good seal, high temperature high voltage resistant and gate valve to open and close that moment is light, the full welding lock formula hard seal ball valve of life-span compensation advantage again.
The utility model welds lock formula hard seal ball valve entirely, comprise valve rod, valve seat and handle, described valve rod is provided with position limit pin, the two ends of position limit pin are fixed by the combined type acorn nut, the contacting point of position limit pin and valve rod is provided with roller, the upper end of valve rod is provided with screw rod, the outside of screw rod is provided with the valve rod support, the upper end of screw rod and handle are fastening by slim nut and plain cushion, be provided with the Stem Mut fixed tray between valve rod support and the handle, the bottom of valve seat is provided with the ball fixed cover, and the outside of valve seat is provided with main valve body, fixing between main valve body and the valve seat by welding, the both sides of valve seat are connected with auxiliary valve body, and also fixing by welding between auxiliary valve body and the valve seat, the valve pocket inside of valve seat is provided with first ball clack and second ball clack, also be provided with the ball wedge in the valve pocket of valve seat, ball is carved and carve row downwards under the drive of valve rod.
The beneficial effects of the utility model are: 1, between main valve body and the valve seat, all adopt the modes of welding to be connected between valve seat and the pipeline, and good sealing effect, though the latus rectum size, the pressure height, and leak-down rate detects and is " zero "; 2, adopt the formula of carving to make up ball, make the sealing that ends that forms the sphere and the conical surface between the metallic sealing section, make and stay gap rotation, less wear between the sealing surface, have again after the wearing and tearing tiltedly to carve and do the life-span compensation, product is prolonged working life greatly, and high temperature high voltage resistant, antistatic, can work as ball valve, can work as gate valve or stop valve or stopcock again and use, can manufacture and design, can manufacture and design by the connection length standard of stop valve or gate valve or stopcock again by the connection length standard of ball valve.3, valve seat, auxiliary valve body and main valve body all adopt seamless steel pipe to make, and have high creep rupture strength, high oxidation resistance and favorable tissue stability.
