Fig. 3 be locknut partly cut open structural representation.
Mark representative in figure: 1 handwheel, 2 pressures are female, meet mother, 4 tetrafluoro packing rings in 3,5 valve gaps, mouth rubber pad in 6,7 slip joints, 8 trim ring flanges, 9 trim ring sealing gaskets, 10 valve bodies, 11 flashboards, 12 flashboards are female, 13 valve rods, 14 sealing O type circles, 15 locknuts, 16 is domestic, 17 cotter ways, 18 bayonet sockets, 19 bonnet flange, 20 pin-and-holes, 21 card ears.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A locknut position structure for gate valve, comprise valve body 10, valve gap 5, flashboard 11, valve rod 13, locknut 15, in connect that female 3, pressure is female 2, slip joint 7 and trim ring flange 8,
The concrete structure of the made valve of the present embodiment is see Figure of description, be described with direction shown in accompanying drawing 1 for convenience of description, the sealing of valve body 10 upper end is fixed with valve gap 5, and be vertically coated with a valve rod 13 in the middle part of valve gap, the valve rod lower end in valve body is vertically fixed with a flashboard; In valve body, be shaped with the runner of lateral direction penetrating, the flashboard blocking runner blocks runner.
In the middle part of flashboard, upper end is fixedly mounted with valve rod 13 by flashboard mother 12, and valve rod protrudes upward valve gap, and the valve stem end above valve gap is provided with handwheel 1, and handwheel controls valve rod and rotates thus drive flashboard lifting, opening and closing valve; Handwheel also can replace with electric actuator or worm gear.
In the middle part of valve rod, coaxial engagement is provided with a locknut 15, and locknut is coaxially inlaid in valve gap upper end, connects female 3 and pressure female 2, presses female lower end coaxially to engage locking with valve gap, ensure that locknut is clamped during the valve rod of locknut upper end is set with successively;
The concrete locking mechanism of locknut is: the outer middle side part symmetry of locknut is shaped with card ear 21, and card ear is inlaid in the made bayonet socket 18 of valve gap upper end inwall; Locknut top is also shaped with pin-and-hole 20, is fixed with domestic 16 in pin-and-hole, is domesticly installed in cotter way 17 made in valve gap, and valve gap and locknut lock are located;
At the runner two ends of valve body, one slip joint 7 is all installed, the lateral ends of slip joint is shaped with the mounting flange (non-label) for connecting, the inner opposite end of slip joint coaxially penetrates in valve body, the trim ring flange 8 be connected with valve seal is set with, the adjustment that coaxially to stretch in trim ring flange of stretching outside this slip joint.In order to ensure the sealing of slip joint, the valve body inside trim ring flange and between slip joint clamping sleeve trim ring sealing gasket 9 is housed.By the length of stretching slip joint regulation valve body during installation, directly can use in the pipeline of multiple distance, construction process is simple, is convenient to on-the-spot adjustment.
In order to ensure that valve seal prevents from revealing, valve gap lower end is shaped with bonnet flange 19, and valve gap is connected with valve body by flange, mouth rubber pad 6 in being provided with between valve body and valve gap; Locknut and in connect between mother, in connect all to pad to be equipped with between mother and pressure mother and seal O type circle 14.
Flexible in order to ensure valve stem slides, in pressure between female and valve rod, in connect all to pad between mother and valve rod tetrafluoro packing ring 3 be housed.
Process modification is:
