Description

The automatic on-off drain valve

Technical field

The utility model relates to a kind of drain valve, relate in particular to a kind of be applicable to metallurgy, chemical industry can automatic on-off drain valve.

Background technique

In metallurgy industry, it is extremely important how to discharge this link of toxic and harmful safely and effectively.The now general employed water separator that is connected with waste pipe often causes gas leakage because of lack of water, and when dilutional hyponatremia, waste water overflows pipeline, causes surrounding enviroment to pollute, therefore, how to prevent toxic and harmful from pipeline excessive or waste water to overflow from pipeline be problem demanding prompt solution.

Summary of the invention

The purpose of this utility model is to provide a kind of drain valve that can automatic on-off, can prevent effectively that toxic and harmful from easily leaking.

The technical solution of the utility model is: the automatic on-off drain valve comprises a cylindrical shell, a hollow pontoon, at least two bird shape hooks, a valve plate, a state mark post; Wherein, described cylindrical shell connects waste pipe in the cylindrical shell bottom, and a side of cylindrical shell is offered a drain opening; Hollow pontoon is positioned at described inner barrel; At least two bird shape hooks are divided into the cylinder inboard wall both sides, and this bird shape hook one end is installed in cylinder inboard wall, and roller is equipped with in the other end end; One end of valve plate directly is connected with the end that described cylinder inboard wall one side bird shape chimoto is equipped with roller, and the valve plate the other end has hung steel wire, is connected with opposite side bird shape hook and hollow pontoon respectively by steel wire; The state mark post is connected the top of valve plate, and stretch out outside the cylindrical shell at this state mark post top.

Further, be provided with a back-up ring on described hollow pontoon, back-up ring is fixed on cylinder inboard wall, is positioned at the top of hollow pontoon, can limit the upper limit of hollow pontoon the sphere of activities.

Set firmly the spline groove at described cylinder inboard wall, prevent hollow pontoon revolution and uneven.

Automatic on-off drain valve of the present utility model is no matter water yield size can both unimpededly be discharged; Close unlatching and be not subjected to the influence of gas pressure size; Closing unlatching adjusts voluntarily according to the height of the water level in the waste pipe.The automatic on-off drain valve is applicable to water seal, pipeline, condensed water outlet devices such as cylinder formula, cartridge type, box, V-type, according to the different size of waste pipe, adopts the automatic on-off drain valve of different size.

Embodiment

As shown in Figure 1, automatic on-off drain valve of the present utility model comprises cylindrical shell 1, hollow pontoon 5, two bird shape hooks 3,3 ', one valve plate 6, a state mark post 2; Wherein, a side of cylindrical shell is offered drain opening; Hollow pontoon 5 is positioned at described cylindrical shell 1 inside; 3 bird shape hooks are divided into the cylinder inboard wall both sides, and this bird shape hook 3,3 ' one end are installed in cylinder inboard wall, and matrix roller 9 is equipped with in the other end end; One end of valve plate 6 directly is connected with the end that roller is equipped with in described cylindrical shell 1 inwall one side bird shape hook 3 ends, and valve plate 6 the other ends have hung steel wire 4, are connected with opposite side bird shape hook 3 ' and hollow pontoon 5 respectively by steel wire 4; State mark post 2 is connected the top of valve plate 6, and stretch out outside the cylindrical shell at these state mark post 2 tops; Flange 11 is equipped with in the bottom of automatic on-off drain valve, directly connects waste pipe.

Hollow pontoon 5 is positioned at the below of inner barrel, raises with the rising of water level, descends with the decline of water level, and spline groove 8 is fixed on cylindrical shell 1 inwall, can prevent hollow pontoon 5 revolutions and uneven.

Back-up ring 7 is fixed on cylindrical shell 1 inwall, is positioned at the top of hollow pontoon 5, the upper limit of restriction hollow pontoon 5 the sphere of activities;

Bird shape hook 3,3 ' is a pair of cylindrical shell 1 inwall that is fixed on, the dress water-sealed bearing, as shown in Figure 1, left side one end is connected with valve plate 6 by steel wire 4, right side one end with directly be connected, bird shape hook 3,3 ' effect are to make valve plate 6 unlatching closed action more freely; The quantity of bird shape hook is the best with 3.

Steel wire 4 connects hollow pontoon 5 and valve plate 6 by the matrix roller 9 on the bird shape hook 3, like this, and along with the height of water level, the lifting of hollow pontoon 5, with regard to can regulate valve plate 6 apertures.

When water level in the waste pipe raise, hollow pontoon 5 float thereupon, promptly as the figure position, at this moment, and by the stretching of steel wire, the valve plate run-off the straight, its aperture is about 50%, i.e. state shown in the figure, flowing water can be from the unimpeded discharging of this opening in a large number;

Water seldom is lower than down in limited time in waste pipe, and hollow pontoon 5 drops to the limit, at this moment, hollow pontoon drives steel wire down, thus make valve plate 6 by as the oblique position of figure to horizontal position, fasten with left side bird shape hook 3 ', at this moment, valve plate 6 is the level of state, and coincide with horn mouth 12 places.The top layer of valve plate 6 is equipped with semicircle rubber, and the bottom of horn mouth 12 is equipped with O type rubber ring, and strict seal when guaranteeing that drain valve valve plate 6 is closed prevents gas leak.State mark post 2 is connected with valve plate 6, state mark post 2 oscilaltion along with the size of valve plate 6 unlatching amplitudes.

The automatic on-off drain valve can be according to the size of waste pipe water-outlet quantity, and valve plate is adjusted voluntarily by the aperture of 50%-0%, and the state mark post has scale can represent the aperture of valve plate, is convenient to observe the working condition of drain valve.
