Abstract
The utility model relates to a valve with an automatic lock nut. the outer wall of the upper part of a valve body is provided with an annular groove and is also provided with two opposite radial groove-shaped openings. A vertical plate of the lower part of a blocking tongue is positioned in the groove-shaped opening, and the periphery of a circular edge of the upper part of the blocking tongue is provided with two opposite open grooves. The depth and the width are all corresponding to a blocking key in the lock nut. central lines of the two open grooves are also vertical to a convex block below the blocking tongue. The height of the blocking key on the inner wall of the lock nut is corresponding to the depth of the annular groove of a valve casing. A spring is arranged between the blocking tongue and the lock nut. The utility model is convenient for management and can effectively control the opening and the closing of the valve.
Description
The utility model relates to a kind of valve, valve that particularly can locking.
In the pipeline of systems such as some industry such as tap water, heat supply, oil, need be provided with can locking valve, and by the locking of special managerial department's control valve.Valve kind at present with lock is a lot, and wherein major part is to come switch by key, and many keys concentrate in together, and also bring very big trouble to managerial department.It is to adopt special tool to open that the small part valve is also arranged, and these valves just can work out the instrument of unlatching by appearance and modeling, make the lockset on the valve ineffective.
The purpose of this utility model is to provide a kind of management but also valve of the automatic lock nut of band that opens and closes of control valve effectively of not only having made things convenient for.
The purpose of this utility model can realize by following measure: a kind of valve with automatic lock nut, it includes valve body, it is characterized in that: near the outer wall the valve casing end top on valve body top is provided with annular groove, also be provided with two relative radially slit openings on this valve casing, be provided with the projection in retaining hypogloeeis in it, its periphery of plectane on retaining tongue top is provided with two opening opposing grooves, its degree of depth and width are all corresponding with the block key in the lock nut, lock nut is provided with the block key of two evaginations near the inwall of opening, its height is corresponding with the valve casing annular groove degree of depth, is provided with spring between retaining tongue and lock nut.The center line of retaining tongue two opening slots is perpendicular with the ranine projection of retaining.Establish the coaxial plectane of diameter above the plectane on retaining tongue top less than it.Coexist in the plane with the following anchor ring of annular groove at the bottom of the opening slot on the valve casing.
The utility model mainly includes valve body, lock nut, retaining tongue and spring.Wherein valve body can be ball valve, gate valve, heat control valve and other valve body, and near the outer wall in tubular valve shell end top of establishing valve rod in its top is provided with annular groove.Also be provided with two relative radially slit openings on above-mentioned tubular valve shell, they are symmetry with the axis of this valve casing.Preferably coexist in the plane with the following anchor ring of annular groove at the bottom of the opening slot.Be provided with the retaining tongue in the slit opening of above-mentioned valve casing, this retaining hypogloeeis is that width is slightly less than the projection that slit opening, length are equal to or less than the valve casing external diameter, its upper end is provided with the plectane that is connected as a single entity with it, its periphery is provided with two opening opposing grooves, the degree of depth of this groove and width are all corresponding with the block key established in the lock nut, and the center line of best two opening slots is perpendicular with the ranine projection of retaining.Under shed circular groove shape lock nut can will keep off tongue and upper valve clamshell within it.The inwall of the close opening of this lock nut is provided with the block key of two evaginations, and its height is corresponding with the valve casing annular groove degree of depth.Between retaining tongue and lock nut, be provided with spring.For making spring location, be provided with the coaxial plectane of diameter above preferably keeping off the plectane on tongue top less than it, it can connect together by fastening piece, also can be one.Position in the groove that the spring lower end can place plectane to constitute.
The block key of the utility model lock nut is positioned at the annular groove that valve body top opens and closes the position, and the projection of retaining tongue will be located the radially slit opening shutoff of valve body, realize the locking function of valve.The utility model can be made into and disposablely uses and reuse two kinds.If disposable lock nut, administrative staff adopt special tool that lock nut is destroyed during use, valve rod is exposed carry out the switch adjustment, and then change a new lock nut.If reusable lock nut, its sidewall adopts copper, aluminium or their alloy material to make, and has only bottom land to be made by carbon steel material.Overcome the elastic force of spring by the special tool that has high magnetic fields, will keep off tongue and upwards attract, and rotate lock nut, when the block key on the lock nut and valve radially during the flute profile register lock nut can take off valve rod exposed and carry out the switch adjustment.
The utility model has following advantage compared to existing technology:
1, simple in structure, reliable performance can't be studied its internal structure principle from the lock nut outward appearance.
2, few, the easy manufacturing of parts, cost is low.
Drawing is described as follows:
Fig. 1 is the utility model partial cutaway schematic.
Fig. 2 is the A-A view of Fig. 1.
Fig. 3 is the B-B view of Fig. 1.
The utility model is described in further detail to utilize the example shown in the accompanying drawing.In the schematic representation of the valve of Fig. 1, Fig. 2 and the automatic lock nut of band shown in Figure 3, near the outer wall in valve casing end top of establishing valve rod 2 in valve body 1 top is provided with annular groove, also be provided with two relative radially slit openings 3 on this valve casing, the following anchor ring of its bottom land and annular groove coexists in the plane, the projection 5 of retaining tongue 4 bottoms places in the above-mentioned radially slit opening, plectane 6 its peripheries on retaining tongue top are provided with two opening opposing grooves 7, its degree of depth and width are all corresponding with the block key 9 in the lock nut 9, and the center line of two opening slots is perpendicular with the ranine projection of retaining.Be provided with the diameter that is connected as a single entity with it coaxial plectane 10 above the plectane on retaining tongue top less than it.The inwall of the close opening of lock nut is provided with the block key of two evaginations, and its height is corresponding with the valve casing annular groove degree of depth.Between retaining tongue and lock nut, be provided with spring 11.
