Abstract
The utility model relates to a self-closing valve which is composed of a valve cover, a valve rod, an elastic sealing sleeve, a sealing ring, a valve body, etc., wherein, the valve rod of the self-closing valve is sheathed with the elastic sealing sleeve, and the lower part of the self-closing valve is provided with a valve plug which can automatically close under the actions of the elastic force of the elastic sealing sleeve and pipeline pressure. The utility model which has the advantages of simple structure and convenient operation is suitable for being arranged on various pressure conduits.
Description
The utility model relates to a kind of self closing stop valve.
The rotary water nozzle valve of people's use now, breakdown will be unscrewed, and closes to screw, and is cumbersome.
The purpose of this utility model provides a kind of self closing stop valve, can close automatically under the elastic force effect of pipeline pressure and elastic force stuffing box gland, and is simple in structure, easy to use.
The utility model mainly is made of valve body, valve gap, valve rod, elastic force stuffing box gland, valve plug etc.Valve stem part places in the valve body, and the upper end connects valve gap or handle, draw ring, and there is valve plug the lower end, and top is with retractable elastic force stuffing box gland.The elastic force stuffing box gland is conical shell shape or hemisphere hull shape, straight garden hull shape, tubaeform, one end overhead-valve lid, and the other end is contained on valve body or the valve rod.Valve when closing, the valve seat place of valve plug in valve body.When external force imposes on valve rod, valve rod drives valve plug and lifts off a seat the valve breakdown; If external force disappears, valve rod drives valve plug and gets back to valve seat, throttle down under the elastic force of elastic force stuffing box gland and pipeline pressure effect.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the sectional view of push type self closing stop valve;
Fig. 2 is a sectional view of lifting pull-type self closing stop valve.
Embodiment 1: with reference to Fig. 1, and the valve rod of push type self closing stop valve | 5| garden column, the upper end connects garden cup-shaped valve gap | 7|, lower end and the garden plate-like valve plug that adheres to rubber ring | the 8| wire connection.Valve rod | 5| and valve body | the hole, garden on the 1| is movingly.Valve plug | 8| places valve seat | below the 4|.Conical shell shape elastic force stuffing box gland | 6| is enclosed within valve rod | on the 5|, upper end overhead-valve lid | 7|, the lower end is contained in valve body | on the dimple of 1|, its inside and outside through respectively with valve rod | 5| and valve body | the dimple of 1| closely cooperates.Valve rod | the relative valve body of 5| | the distance of 1| moving linearly is less than or equals the elastic force stuffing box gland | the distance that the 6| both ends of the surface can shorten, can pass through control valve plug | 8| realizes.Port lid is installed | 3| is used to install valve plug | and 8| is in valve body | the bottom of 1|, with valve body | and the 1| silk connects, and seal ring is arranged | and 2| places between the two.
Embodiment 2: with reference to Fig. 2, lift the valve rod of pull-type self closing stop valve | and 5| is the garden column, upper end catcher handle | 3|, there is garden dish type platform at the middle part, and the lower end is the garden plate-like valve plug that adheres to rubber ring | 8|.Valve rod | 5| and valve gap | the hole, garden on the 7| is movingly.Valve plug | 8| places valve seat | on the 4|.Conical shell shape elastic force stuffing box gland | 6| is enclosed within valve rod | on the 5|, garden, last top cup-shaped valve gap | 7|, a following valve rod | the garden dish type platform of 5|, external diameter closely cooperates with valve rod and valve gap respectively in it.Valve rod | the relative valve body of 5| | the distance that the distance of 1| moving linearly is less than or equals can shorten between the elastic force stuffing box gland both ends of the surface.Valve gap | 7| and valve body | 1| is threaded, and adorns seal ring between the two | 2|.
The rubber manufacturing of elastic force stuffing box gland, seal ring, miscellaneous part is with metal or plastics manufacturing.
The utility model is fit to be installed on the various pressure pipings.
