Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of convenient fixing and the gate valve cover easily fixed of a kind of Stem Mut of good fixing effect.
For achieving the above object, the utility model provides following technological scheme:
The gate valve cover that a kind of Stem Mut is easily fixed, comprise valve gap base and be arranged on valve rod mounting blocks above valve gap base, valve rod mounting blocks is provided with Stem Mut, described valve rod mounting blocks top offers the first long strip groove near madial wall, described Stem Mut outer side wall is provided with the second long strip groove vertically, described first long strip slot length is less than the height of valve rod mounting blocks, also comprises the locating stud by the first long strip groove and the second long strip groove phase clamping.。
Pass through technique scheme, when Stem Mut needs fixing time, only need Stem Mut to be put on valve rod mounting blocks, first long strip groove and the second long strip groove are aligned, just define a locating slot, then inserting locating stud can be undertaken simple and effective fixing by valve body nut and valve rod mounting blocks, and due to locating stud be insert from the top of valve rod mounting blocks, also just without the need for the risk easily spun off of horizontal location, and locating slot does not offer screw thread, do not worry that the problem of getting rusty does not need oily yet.
Of the present utility modelly be set to further, described valve rod mounting blocks madial wall is provided with ladder-type annular protrusion.
Of the present utility modelly be set to further, described ladder-type annular protrusion comprises the first annulus, and described first annulus convex inner surface is provided with the second annulus.
Of the present utility modelly be set to further, described second annulus height is less than the first annulus.
By technique scheme, because Stem Mut is divided into three sections, diameter diminishes from top to down, can better to fit Stem Mut so be provided with the first annulus and the second annulus, makes fixing more firm on valve rod mounting blocks of nut.
Of the present utility modelly be set to further, described first long strip groove and the second long strip groove can be many groups.
By technique scheme, can realize organizing location more, can realize fixing more firm.
The utility model is set to further, and described first long strip groove is identical and suitable with the second long strip slot length.
By technique scheme, what the identical energy of shape size length was convenient makes locating stud insert, and is more easy to fixing.

In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Embodiment
Embodiment with reference to the easy fixing gate valve cover of a kind of Stem Mut 3 of accompanying drawing 1 to 4 pair of the utility model is described in further details.
With reference to Fig. 1,2,3, a kind of gate valve cover, comprise valve gap base 1 and be arranged on valve rod mounting blocks 2 above valve gap base 1, valve rod mounting blocks 2 is provided with Stem Mut 3, valve rod mounting blocks 2 top offers the first long strip groove 21 near madial wall, Stem Mut 3 outer side wall is provided with the height that the second long strip groove 31, first long strip groove 21 length is less than valve rod mounting blocks 2 vertically, and the first long strip groove 21 is identical and suitable with the second long strip groove 31 length.First long strip groove 21 and the second long strip groove 31 can be many groups, preferably select four groups circumferentially evenly to arrange, can realize organizing location more, can realize fixing more firm.The shape of the first long strip groove 21 and the second long strip groove 31 can be rectangular, in use, when Stem Mut 3 needs fixing time, Stem Mut 3 is only needed to put on valve rod mounting blocks 2, first long strip groove 21 and the second long strip groove 31 are aligned, just define a locating slot, corresponding locating stud 4 also for the cuboid of locating slot can be inserted, then insert locating stud 4 and valve body nut and valve rod mounting blocks 2 can be carried out simple and effective clamping, define fixing, and due to locating stud 4 be insert from the top of valve rod mounting blocks 2, also just without the need for the risk easily spun off of horizontal location, and locating slot does not offer screw thread, do not worry that the problem of getting rusty does not need oily yet, processing is simply easy to produce.First long strip groove 21 is identical and suitable with the second long strip groove 31 length, and what the identical energy of shape size length was convenient makes locating stud 4 insert, and is more easy to fixing.
With reference to Fig. 4, Stem Mut 3 is divided into three sections, and diameter diminishes from top to down, so can leave gap when being arranged on valve rod mounting blocks 2 inside, exert a certain influence for the stability that Stem Mut 3 is fixing like this, valve rod mounting blocks 2 madial wall is provided with ladder-type annular protrusion.Ladder-type annular protrusion comprises the first annulus 22, first annulus 22 convex inner surface and is provided with the second annulus 23, second annulus 23 and is highly less than the first annulus 22.Being provided with the first annulus 22 and the second annulus 23 can make the profile of Stem Mut 3 better fit Stem Mut 3, makes fixing more firm on valve rod mounting blocks 2 of nut.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
