Description
technical field:
The utility model relates to a kind of band seat globe valve.
background technique:
Ball valve all presents sphere at inlet/outlet place, thus block flowing.Because it is tight that ball valve only needs the operation of 90-degree rotation and very little moment of rotation just can close, and the runner that the body cavity opened completely to be medium provide resistance is very little, straight-through, have and be suitable for directly doing opening and closing use, also can be used as the use of throttling and control flow.Particularly its compact structure, is easy to Operation and maintenance, is applicable to water, solvent, acid and rock gas working medium.Existing ball valve lacks fixing device, easily cause loosening between ball valve and connection pipe fitting after a protracted use, and ball valve use for a long time after easily to there is the accumulation of dirt at valve ball place, dirt is difficult to cleaning, makes the working life that ball valve cannot reach desirable.
summary of the invention:
The purpose of this utility model is to solve the problems of the prior art, provides a kind of and install firmly, not easily loosens and not easily produce the band seat globe valve of dirt.
In order to achieve the above object, the technical solution of the utility model is:
A kind of band seat globe valve, comprise valve body, offer fluid passage in described valve body, described valve body offers the first connecting head and the second connecting head, described valve inner is provided with valve ball; Described valve body is provided with extension tube, with on the opposite side of the valve body of described extension tube symmetry, fixed base is installed; Be provided with rotating shaft in described extension tube, the two ends of described rotating shaft are connected with valve ball and switch respectively; The side of described extension tube is provided with limiting stopper.
Described fluid passage is connected with valve ball, and described fluid passage offers contraction flow region on the inwall of valve ball side.
Offer connecting groove in described second connecting head, offer internal thread in described connecting groove, the connecting groove of described female ends offers buffer wall, it is trapezoidal seal ring that described buffer wall and intersection, fluid passage are provided with cross section.
Described switch offers mounting hole, is provided with screw in described mounting hole, described screw and rotating shaft are fixedly linked; Described switch is also provided with inserted part, described inserted part and limiting stopper activity clamping.
Described fixed base comprises joint and fixed base, the bottom surface of described fixed base offers the first groove, offers the second groove in described first groove, is provided with magnet piece, described magnet piece is provided with rubber pad in described second groove.
The thickness sum of described magnet piece and rubber pad is less than the groove depth of the second groove.
The beneficial effects of the utility model are: one band seat globe valve of the present utility model, valve body is provided with fixed base, the bottom surface of fixed base offers the first groove and the second groove, the first groove can be connected with other lug bosses with the second groove, stability when increasing fixing; Offer contraction flow region in fluid passage, contraction flow region can accelerate the flow velocity by valve ball fluid, reduces the generation of dirt in valve ball.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
embodiment:
Embodiment 1
One band seat globe valve as shown in Figure 1, is characterized in that: comprise valve body 1, offers fluid passage 11 in described valve body 1, and described valve body 1 offers the first connecting head 2 and the second connecting head 3, described valve body 1 inside is provided with valve ball 4.Described fluid passage 11 is connected with valve ball 4, and described fluid passage 11 offers contraction flow region 12 on the inwall of valve ball 4 side.Contraction flow region 12 can accelerate the flow velocity by valve ball 4 fluid, reduces the generation of dirt in valve ball 4.
Connecting groove 31 is offered in described second connecting head 3, internal thread 32 is offered in described connecting groove 31, the connecting groove 31 of described internal thread 32 end offers buffer wall 33, and it is trapezoidal seal ring 34 that described buffer wall 33 is provided with cross section with intersection, fluid passage 11.When buffer wall 33 prevents pipe fitting from connecting, convection cell passage 11 causes damage, and seal ring 34 not only has sealing function, also has the effect of buffering.
Described valve body 1 is provided with extension tube 6, with on the opposite side of the valve body 1 of described extension tube 6 symmetry, fixed base 9 is installed.Be provided with rotating shaft 7 in described extension tube 6, the two ends of described rotating shaft 7 are connected with valve ball 4 and switch 8 respectively; The side of described extension tube 6 is provided with limiting stopper 61.
Described switch 8 offers mounting hole 84, is provided with screw 85 in described mounting hole 84, described screw 85 is fixedly linked with rotating shaft 7; Described switch 8 is also provided with inserted part 83, described inserted part 83 and limiting stopper 61 activity clamping.Inserted part 83 can limiting rotating angle when switch 8 rotates, and guarantees not have deviation when controlling valve ball 4 break-make.
Described fixed base 9 comprises joint 91 and fixed base 92, the bottom surface of described fixed base 92 offers the first groove 93, offer the second groove 94 in described first groove 93, in described second groove 94, magnet piece 95 is installed, described magnet piece 95 is provided with rubber pad 96.Magnet piece 95 can attract the lug boss of metal when fixing, is convenient to install, and too increases the stability of fixed base 9.Magnet piece 95 is frangible, so installed rubber pad 96 on magnet piece 95, for the protection of magnet piece 95.The thickness sum of described magnet piece 95 and rubber pad 96 is less than the groove depth of the second groove 94, makes also to can be used for being fixedly connected with in the second groove 94.
