Background technique:
Existing orbit ball valve point whole ball, combination ball and elastic groove structure.Wallowing motion combination spherical ball valve or elastic groove spherical ball valve are equipped with steel combination ball or whole ball of band elastic groove and steel valve seat, and the spheroid lower end is universal joint mechanism or positioning shaft, and mechanism is held together for support in the upper end; Its advantage is that all-pass footpath, fluid resistance are little, saves power source; Adapt to that high-temperature high-pressure medium, open and close torque are light, to open and close velocity ratio gate valve, stop valve fast etc.But whole ball or combination ball are all swung to the seat angle degree by universal joint mechanism center or elastic groove terminal; When pressing to valve base sealing, generally be that following of valve seat ring surface contacts with spheroid at first, last last contact; Make the following sealing earlier of valve seat ring surface, the sealing of last back.During unlatching, last disengagement earlier, throw off more following back, thereby cause seal pressure unbalanced, and the medium erosion that is stressed is uneven, and reduced the working life of valve; The whole spherical ball valve of wallowing motion relies on the mechanical keys power of valve rod to force spheroid and valve base sealing can only form one-way sealing simultaneously, and the flow direction is restricted, and installation direction is also restricted; And valve rod finally causes switch dumb, poorly sealed owing to be monolateral stressed yielding bending, and working life is short; Be prone to slagging scorification in the clip slot of wallowing motion combination ball or elastic groove spherical ball valve universal joint mechanism or in the elastic groove, spheroid can't be received support after the slagging scorification, and ball valve can't use.
The model utility content:
To the technical deficiency of existing the said goods, the purpose of the utility model just provides a kind of rail mounted two-way hard seal ball valve, and it is made up of valve body, back shaft, combination spheroid, roller, valve rod, valve gap, support, guide roller, spiral chute etc.
The utility model solves the technological scheme that its technical problem adopted: valve adopts goes up dress formula structure, and the combination spheroid is combined by two hemisphere lobes; The lower end of the part that is harmonious of two hemisphere lobes is provided with a back shaft, and two ball clacks are holding back shaft and strutting, close up, and nimbly and freely, described back shaft is for being the cylindrical body of " T " shape; Two hemisphere lobe upper ends respectively are provided with two rollers.
Support is provided with spiral chute; Bearing pin is equipped with at the valve rod middle part, and the bearing pin two ends respectively have a guide roller to put in spiral chute, and described spiral chute is " Z " type spiral chute.
The structure of valve rod lower end is a wedge, wedge a roller each side arranged, the inboard of wedge is provided with two rollers; Described wedge is up big and down small, and V-shaped shape is when the wedge lower edge; Wedge will make up ball and strut, and located by roller when promoting wedge, and the combination ball closes up.
The utility model beneficial effect: energy saving, do not receive MEDIA FLOW to restriction and can to install and use, can not produce slagging scorification, coking, operation moment of torsion arbitrarily little, long service life, not only reliable, good rigidly, and have and close tighter function more.

Fig. 2 is the utility model spheroid, back shaft schematic representation.
Among Fig. 1,1 valve body, 2 back shafts, 3 combination spheroids, 4 rollers, 5 valve rods, 6 valve gaps, 7 supports, 8 guide rollers, 9 spiral chutes
Among Fig. 2,2 back shafts, 3 combination spheroids, 4 rollers, 5 valve rods, 10 wedges
Embodiment:
Like accompanying drawing 1, shown in 2, the purpose of the utility model just provides a kind of rail mounted two-way hard seal ball valve, and it is made up of valve body 1, back shaft 2, combination spheroid 3, roller 4, valve rod 5, valve gap 6, support 7, guide roller 8, spiral chute 9.When needs are opened valve, be rotated counterclockwise handwheel, valve rod 5 begins rising, and wedge 10 closes up combination spheroid 3 and sealing surface of seat disengaging because spheroid 3 will be made up in roller 4 location; When valve rod 5 continued to promote, the guide roller 8 on the valve rod 5 began rotation along " Z " type spiral chute 9 on the support 7, had been with combination spheroid 3 to rotate 90 degree, valve open under the abrasion state not having with sealing surface of seat simultaneously.
When wanting throttle down, the handwheel that turns clockwise, the guide roller 8 on the valve rod 5 begins the lower edge while rotating along the track of spiral chute 9, is being with combination spheroid 3 to revolve together simultaneously and is turning 90 degrees; When valve rod 5 continuation lower edges, wedge 10 will make up spheroid 3 and strut, and the back shafts 2 that are clipped in the middle of the combination spheroid 3 are brought into play cam action simultaneously, the ball clack that will make up spheroid 3 synchronously abreast to the sealing seat at the inlet/outlet two ends of valve near, valve closing.
Because this is suitable for the reliable sealing principle with long service life of novel employing stop valve sealing, strut ball clack and be adjacent to valve seat and press to valve seat to form sealing the same as parallel the moving of stop valve flap, do not have scratch, wear and tear for a short time, be not afraid of and attach granule medium on the sealing surface.When combination spheroid 3 rotarily opened valve, ball clack and valve base chamber were gapped, were not rotating under the contact condition, so more there are not wearing and tearing, the operation moment of torsion is little, long service life.The space that in combination spheroid 3 rotary courses, forms with valve seat simultaneously makes pipeline medium flow velocity increase, thereby reaches the flushing seal action.
Wedge 10 is connected with combination spheroid 3 and adopts wedge-like to connect, and closes at low temperatures, Open valve can not rise extremely because of combination spheroid 3 high temperature expand yet during high temperature.Adopt gate valve wedge shape flashboard method to support ball clack simultaneously, not only reliable, good rigidly, and have the tighter function in pass more, and its particular structural can provide the tightening seal of a mechanical wedge-type pretightening force to guarantee to continue.Even behind sealing surface wear, also can obtain the life-span compensation.
Because two ball clacks lump together the transition by back shaft 2 mutually; Can not produce slagging scorification, coking phenomenon between the combination spheroid 3, adopt the rising stem (RS.) method for opening and closing of gate valve simultaneously, make the open and close torque of ball valve equally light with gate valve; And the utility model valve body 1 adopts upward dress formula structure; Have last sealing function, and can adapt to high-temperature high-pressure medium, have high parameter and frpf functional requirement.
