Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Shown in Fig. 1-4, a kind of upper dress formula C type ball valve comprises valve body 1, valve seat 2, spool 3, valve gap 4 and upper valve rod 5 and lower valve rod 6, described valve body 1 comprises the control mouth that is formed on both sides water intake and water outlet and setting and the perpendicular direction of flow velocity direction, described valve gap 4 is fixedly installed on described control mouth place, described spool is C shape and is integrally formed with described upper valve rod, described upper valve rod is connected with drive unit through described valve gap and keeps sealing to contact with valve cover chamber, described valve body and a control mouthful relative opposite side, bottom is formed with mounting hole, the lower valve rod 6 that afterbody is bolted to connection with valve body from bottom, penetrate to valve inner and with rotatable cooperation of C shape spool, described valve seat is arranged on valve inleting water mouth side and contacts with described seal spool when ball valve is closed.
The present invention combines upper dress formula and C shape ball valve, it is stressed that upper dress formula structure has effectively been alleviated spool, it only bears hydrodynamic pressure and not disturbed by pipe stress, than side-mounted stability, be greatly improved, the ball core of upper-mounting type ball valve is arranged on valve body by valve gap simultaneously, in valve, break down in the time of need to repairing, needn't dismantle valve from pipeline, the valve gap of need only dismantling, valve gap and valve core valve stem assembly parts are taken off from valve body together, can repair online spool and valve seat, the time has been saved in this maintenance, reduces the loss in producing.Specifically, C shape spool is that a global shell is cut into the shape that cross section is C, is a sphere tabular, its top is fixedly connected with or is integrally formed with valve rod, its bottom is formed with lower valve rod and rotates mutually the through hole coordinating, and the one-board structure of C shape designs for full-bore simultaneously, when opening state without dead space, reduce flow resistance, resistance to erosion, without material stagnant area, medium in valve pocket all in flowing state, effectively prevent medium fouling, C shape spool and valve seat have self-cleaning function in switching process.Preferably, outwards heave with the maintenance spacing with opening the C shape spool of state at described valve body middle part, and the design of spacing is advisable to meet actual conditions.
Wherein, described valve seat is fixedly connected with valve body but is radially having predetermined amount of movement, is provided with spring press-cover 8 between valve seat and valve body simultaneously, in the both sides of described spring press-cover, is provided with Sealing.Adopt and be spring-loaded and removable design, sealing is reliable, and having improved valve seat is C shape seal spool effect and endurance, is provided with Sealing in the both sides of described spring press-cover simultaneously, can prevent that impurity and foul from entering spring chamber, effectively prevents spring failure.
Described C shape spool is two eccentric single valve seat structures, adopt two eccentric structures to make C shape spool have cam wedging effect to valve seat, adopt spool and upper valve rod integrative-structure simultaneously, guarantee coaxality, wherein, the through hole that described valve gap coordinates with upper valve rod is that base diameter becomes large shoulder hole, the seam formula design that lower end adopts matches and can play the effect of top radial location with the top of spool, simultaneously, described lower valve rod upper end portion is the ladder axis structure that diameter diminishes, the part coupling that diameter is little is inserted the bottom matching hole of C shape spool, a support when providing running shaft to spool, its section also can be provided, utilize valve gap and lower valve rod to bear spheroid radial force design and make the work that valve can be reliably and with long-term.While valve rod and C shape spool contact position, and the equal metallurgy melting surfacing of C shape spool and valve gap contact position wearing layer, as Ni260AL, more than HRC60, at spool and valve gap contact position and the equal pile-up welding hard alloy of lower valve rod and spool contact position, guarantee can not wear and tear and become flexible in long-term using process, make the work that valve can be reliably and with long-term.
Specifically, C shape spool adopts stainless steel manufacture, the whole surfacing wearing layers of C shape spool face, as Ni260AL, HRC60-62, after processing, thickness is not less than 0.7mm, the metallurgical melted join of spool base material and surfacing, C shape spool inner flow passage face and lip place pile-up welding hard alloy, guarantee that spool has high abrasion resistance and high abrasion resistance.Valve seat adopts stainless steel forgings manufacture, sealing surface surfacing wearing layer, as Ni260A, HRC58-60, thickness >=2mm after processing, the metallurgical melted join of valve seat base material and surfacing, simultaneously valve seat internal channel pile-up welding hard alloy, guarantee that valve seat has high abrasion resistance and high abrasion resistance, abrasion-proof structure design everywhere has greatly promoted product overall quality.
Working principle of the present invention is: in the present invention, fill the design that the eccentric wear resistance ball valve of formula C type adopts valve gap and lower valve rod supporting C-shaped spool, pressure medium is born by valve gap and lower valve rod, in the present invention, fill the eccentric wear resistance ball valve of formula C type at the equal pile-up welding hard alloy of C shape spool and valve gap contact position, simultaneously at the equal pile-up welding hard alloy of lower valve rod and C shape spool contact position, guarantee can not wear and tear and become flexible in long-term using process, make the work that valve can be reliably and with long-term.In the present invention, fill on the C shape spool of the eccentric wear resistance ball valve of formula C type and pack valve body into, with valve gap, C shape spool is inserted in from above, play a supporting role, installing/dismounting is simple and easy.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
