Description
Technical Field
The utility model relates to a stop valve, in particular to a stop valve slipknot bolt torque indicating structure.
Background
The shut-off valve is a valve with a closing member (valve clack) moving along the central line of a valve seat, and mainly has the functions of adjustment and cutting-off in a pipeline. In some special operating conditions, it is common to increase the dynamic load design at the valve packing slip joint bolt out due to the provision of low leakage requirements. However, at present, most valves are only provided with loads applied to the slipknot bolts adjusted by manufacturers when the valves leave factories, the loads on the slipknot bolts are not detected after the valves are used under working conditions, and the slipknot bolts can only be adjusted regularly according to experience of field personnel.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a stop valve slipknot bolt torque indicating structure, which solves the problems that the load applied to a slipknot bolt is well adjusted by a manufacturer when the existing stop valve leaves a factory, the load on the slipknot bolt is not detected after the stop valve is used under a working condition, and the slipknot bolt can be regularly adjusted only by the experience of field personnel.
In order to solve the technical problems, the utility model provides the following technical scheme: the utility model provides a stop valve slipknot bolt moment of torsion instruction structure, includes valve body, eyelet bolt, clamp plate, dish spring, pointer, nut, sign, pressure cover and packs, both ends are rotated through round pin axle symmetry and are connected with eyelet bolt, two about the valve body movable mounting has the clamp plate on the eyelet bolt, eyelet bolt is located and installs dish spring, pointer and nut respectively from the bottom up on the clamp plate, the nut passes through threaded connection with eyelet bolt to the nut compresses tightly on the pointer, the left and right sides of clamp plate and the corresponding position difference fixedly connected with sign of eyelet bolt, clamp plate bottom movable mounting has pressure cover and packs, the packing is located the pressure cover below.
On the basis of the scheme, the swing bolt is in sliding fit with the pressure plate.
On the basis of the scheme, the pointer corresponds to the direction board.
On the basis of the scheme, load numerical values of the disc springs at different heights are engraved on the indicating plate.
Compared with the prior art, the utility model has the beneficial effects that: a stop valve slipknot bolt torque indicating structure adopts a new structure, improves a stop valve, welds a sign outside a pressing plate, can effectively indicate the loading condition of a slipknot bolt on the working condition site through a pointer, is convenient for site personnel to pre-tighten a filler in time, and prevents major leakage.

The reference numbers in the figures are: 1-valve body, 2-swing bolt, 3-pressing plate, 4-disc spring, 5-pointer, 6-nut, 7-indication board, 8-pressing sleeve and 9-filler.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, are merely for convenience of description of the present invention, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.
Referring to fig. 1, the stop valve slipknot bolt torque indicating structure comprises a valve body 1, a slipknot bolt 2, a pressure plate 3, a disc spring 4, a pointer 5, a nut 6, an indicating plate 7, a pressing sleeve 8 and a filler 9, wherein the left end and the right end of the valve body 1 are symmetrically and rotatably connected with the slipknot bolt 2 through a pin shaft, the two slipknot bolts 2 are movably provided with the pressure plate 3, the slipknot bolt 2 is positioned on the pressure plate 3 and respectively provided with the disc spring 4, the pointer 5 and the nut 6 from bottom to top, the nut 6 is in threaded connection with the slipknot bolt 2, the nut 6 is tightly pressed on the pointer 5, the positions of the left side and the right side of the pressure plate 3 corresponding to the slipknot bolt 2 are respectively and fixedly connected with the indicating plate 7, the pointer 5 and the indicating plate 7 are mutually matched to visually indicate the load condition of the slipknot bolt 2, the bottom end of the pressure plate 3 is movably provided with the pressing sleeve 8 and the filler 9, the packing 9 is positioned below the pressing sleeve 8, and the pressing sleeve 8 and the packing 9 are both of the existing mature structure of the valve.
The movable joint bolt 2 is in sliding fit with the pressure plate 3, so that the pressure plate 3 can conveniently move up and down on the movable joint bolt 2; pointer 5 and sign 7 correspond to each other, be carved with the load numerical value when dish spring 4 is located different heights on the sign 7, pointer 5 uses with the sign 7 cooperation, can very audio-visual 2 load conditions of swing bolt of seeing.
The principle and the advantages of the utility model are as follows: a stop valve slipknot bolt torque indicating structure adopts a new structure, improves the local part of a valve, and is provided with a pointer 5 and an indicator 7 which are matched with each other for use, so that the load condition of a movable joint bolt 2 can be visually seen, a field worker can conveniently pre-tighten a filler 9 of the valve through the load condition of the movable joint bolt 2, the valve can be prevented from being seriously leaked, and the use safety of the valve is greatly improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
