Abstract
The utility model provides a spherical gate valve, which comprises a valve body, a valve cover, a support, a valve rod, a gate disc and valve clacks. The valve rod is connected with the gate disc arranged inside the valve body, a guide pin is transversely arranged on the valve rod, two ends of the guide pin are equipped with guide rings, the support is equipped with continuously axial slide grooves and spiral guide grooves, the continuously axial slide grooves and the spiral guide grooves which are arranged on the guide rings and two lateral walls of the support are engaged with each other, the gate disc is equipped with wedge-type cones, the left valve clack and the right valve clack are spherical valve clacks, the gate disc is engaged with T-shaped grooves arranged on the spherical valveclacks on two sides through the wedge-type cones, and then is connected with the spherical valve clacks, a lower adjusting pad, an upper adjusting pad and a planar bearing are further arranged insidethe valve body, the lower adjusting pad is arranged below the spherical valve clacks, the upper adjusting pad and the planar bearing are arranged above the spherical valve clacks, and the planar bearing is arranged between the adjusting pads and the spherical valve clacks. After utilizing the design, the spherical gate valve has the advantages of short start and stop time, wear resistance, convenient maintenance and operation and long service life and the like.
Description
Technical field
The utility model relates to a kind of sphere gate valve.
Background technique
Gate valve is present most widely used valve products, be used for the transmission of control media in fields such as oil, chemical industry, metallurgy, electric power, light industry pharmacy, have advantages such as negotiability is strong, flow resistance is little, the self-locking antivibration is good, high temperature resistant, high pressure, but because its intrinsic structure, when also having following several point defects 1, switching simultaneously, flashboard displacement distance is big, and opening and closing time is long, inefficiency; 2, the friction factor between the sealing surface is big, the quick abrasion of sealing surface, and working life is short.
It is long that the general relative gate valve of sphere gate valve has solved opening and closing time, sealing surface wear is fast, the problem that working life is short, but because of after its limited ring, position-arresting disk be fixed on the valve interior wall, the adjustment of flap is limited, limited ring contacts firmly with flap, and during the flashboard rotation, limited ring is that face contacts with the flap surface of contact, frictional force is big, so operational torque is big, if operation is too frequent, the serious wear of limited ring and flap; And limited ring is fixed on the valve body, for maintenance work has brought very big inconvenience.
Summary of the invention
Technical problem to be solved in the utility model provides the sphere gate valve that a kind of opening and closing time is short, not easy to wear, be convenient to housekeeping operation, life-span length.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of sphere gate valve, comprise valve body, valve gap, support, valve rod, flashboard, flap, flashboard in valve rod and the valve body is connected, laterally assemble guide finger on the valve rod, the guide finger two ends have guide ring, and support is provided with continuous axial slide and spiral guide slot, and chute and spiral guide slot continuous on guide ring and the support two side match; Described flashboard is provided with the wedge-type centrum, left and right sides flap is the sphere flap, flashboard matches by the T type groove that wedge-type centrum and both sides sphere flap are provided with, realization links to each other with the sphere flap, valve inner also is provided with down spacer, goes up spacer and plane bearing, following spacer is located at the below of sphere flap, and last spacer and plane bearing are located at the top of sphere flap, and plane bearing places between spacer and the sphere flap.
The utility model is by above-mentioned specific design, its negotiability is strong, flow resistance is little, self-locking performance and good anti-vibration, keying speed is fast, opening and closing time is short, does not have friction relatively between the sealing surface, because spacer and plane bearing and sphere flap are contained in the valve body, the sphere flap is rolling friction when rotating, friction factor is little, and spacer and plane bearing is non-is completely fixed, and safeguards to dismounting to bring great convenience.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a kind of embodiment's of the utility model sphere gate valve a structural representation.
Fig. 2 is the structural representation of support, valve rod and guide finger.
Fig. 3 is the cross-sectional structural representation of flashboard and sphere flap.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, a kind of embodiment of the utility model sphere gate valve, comprise valve body 1, valve gap 8, flashboard, sphere flap 4, valve rod 7 and support 9, laterally assemble guide finger 10 on the valve rod 7, guide finger 10 two ends have guide ring 14, support 9 is provided with continuous axial slide 12 and spiral guide slot 11, and chute 12 and spiral guide slot 11 continuous on guide ring 14 and support 9 two sides match.Valve rod 7 is connected with flashboard, and flashboard is provided with wedge-type centrum 2, and flashboard matches by the T type groove 15 that wedge-type centrum 2 and both sides sphere flap 4 are provided with, and realizes linking to each other with sphere flap 4.Spacer 6, following spacer 3, plane bearing 5, sphere flap 4 also are equipped with in valve body 1 inside, following spacer 3 places the below of sphere flap, last spacer 6 and plane bearing 5 place the top of sphere flap 4, and plane bearing 5 places between spacer 6 and the sphere flap 4.The position of last spacer 6 and following spacer 3 control sphere flaps 4 enables to seal up, and plane bearing 5 makes the sphere flap be rolling friction in the process of half-twist, and friction factor is little, and this kind assembles also easy disassembly maintenance simultaneously.Present embodiment has also adopted umbrella shape hand behaviour mechanism, and its handwheel 13 is little, easy to operate.
In the process of opening, valve rod 7 is chute 12 drive flashboards risings vertically earlier, when flashboard rises under the effect of wedge-type centrum 2 and the T type groove of sphere flap 4, sphere flap 4 upwards draws in, sealing surface is broken away from, and guide finger 10 is under the restriction of spiral guide slot 11 then, and valve rod 4 drives flashboard and rises and half-twist, sphere flap 4 because of the restriction of last spacer 6 and plane bearing 5 with the flashboard half-twist but do not rise valve opening.
Otherwise when valve closing, sphere flap 4 is with flashboard half-twist in valve body 1, sphere flap 4 can not descend with flashboard because of the restriction of following spacer 3, can only under the effect of wedge-type centrum 2, strut along T type groove, make sealing surface fit, realize valve closing to both sides.
