Description
Technical field
This practicability relates to valve technology field, particularly relates to a kind of Novel Brake Valve.
Background technique
Gate valve is an open-shut device flashboard, moving direction and the flow direction of flashboard are perpendicular, when valve has not allowed the phenomenon that leaks outside, and one of approach leaked outside is medium leaks from valve rod, therefore the Seal Design of stem structure is extremely important, on market a lot of valve products be all because valve rod leak-proof structure design good not, certainly some other approach that leak outside are also had, leaking outside such as between valve seat insert and flashboard, sealing between valve seat and valve body leaks outside, defect of wanting to leak outside can make product occur, and working life is short and using effect is poor, even because this defect causes work safety accident.
Model utility content
For the deficiencies in the prior art, the utility model provides a kind of Novel Brake Valve, and this Novel Brake Valve product using effect is good, and product hermeticity can be excellent.
To achieve these goals, the technological scheme that the utility model provides is as follows: a kind of Novel Brake Valve, comprise valve body, valve rod, flashboard and valve seat, valve rod is connected with flashboard upper end and is arranged in valve body, flashboard lower end is connected with valve seat, valve seat is arranged on valve body lower end, described valve rod is provided with handwheel, handwheel is provided with and cap above handwheel, valve rod is provided with packing seal structure and Stem Mut, described packing seal structure is made up of stuffing box, filler and gland, and filler is arranged in stuffing box, and described gland is arranged on above filler; Be provided with filler spacer ring in the middle of filler, this filler spacer ring is hollow structure, is provided with seal gease in described hollow structure, and described filler spacer ring inner ring surface is provided with bleeding holes; Stem Mut structure is made up of Nut pole and nut cap, and described Nut pole is provided with oil nozzle, and oil nozzle is arranged on Nut pole inwall, and described oil nozzle is cone structure; Adopt metal waveform gasket seal between valve flange, valve body and valve base chamber are provided with valve base sealing structure, and described valve base sealing structure is double seal, and this double sealing structure is made up of soft seal and hard sealing; Described flashboard is provided with pod apertures structure.
The beneficial effects of the utility model are the gate valves designed by said structure, valve rod is in packing seal structure part, filler is when using certain hour, the filler spacer ring in filler neutral position is arranged on by the extruding of gland, the seal gease being arranged on filler spacer ring inside oozes out in the bleeding holes of filler spacer ring, simultaneously good in maintenance " bearing effect " and " labyrinth effect " again at the reliable sealing that ensure that valve rod, ensure that the stabilized seal effect of filler, simultaneously because Stem Mut structural design partial design has oil nozzle, add oiling agent by this oil nozzle place to lubricate this part valve rod, also reach certain sealing effect simultaneously, double sealing structure design between valve rod lower value seat and valve body is further to having carried out good isolating seal between valve stem part and valve channel, with the valve of pod apertures structural design, no matter standard-sized sheet or full-shut position, flashboard and valve seat contact with each other all the time, and sealing surface can not be washed away by medium, thus extend the life-span of this part sealing effect and improve the stability of sealing effect, can find out in sum, the Novel Brake Valve that this structural design provides structurally has done very large improvement, can well make up prior art Related product structural imperfection and cause the relevant issues caused that leak outside.
