A kind of taper discharging valve relates to a kind of dispensing valve device of crystallizer of control feeding valving, particularly metallurgy chemical process of solid-liquid mixture material.

Technical background

In metallurgy chemical process, in the container that the solid-liquid mixture material is housed, the container that is loaded with solid-liquid mixture as crystallizer etc. is when the blowing of bottom, the position that liquid outlet is connected with flange, because deposition of solid blocks easily, causes the blowing difficulty, makes troubles to production operation.

Summary of the invention

The purpose of this utility model is the deficiency that exists at above-mentioned prior art, provides a kind of and can effectively solve because deposition of solid blocks vomit pipe, causes the taper discharging valve of production operation difficult problem.

The purpose of this utility model is achieved through the following technical solutions.

A kind of taper discharging valve is characterized in that this valve blowing is made up of following structure:

Valve body upper shell-this upper shell is the spherical hollow space housing that a upper and lower part all has round breach, and attached method orchid outside the upper and lower opening place of housing has respectively has drain hole and is connected with vomit pipe on the sidewall of housing; Be arranged circumferentially sheet rubber on the spherical hollow space inner walls in the upper shed of housing;

Valve body lower shell body-this housing is that the middle part is a spherical hollow space housing; Top is the flange arrangement that matches with valve body upper shell lower flange and connect of upwards flaring type that combine as a whole with lower shell body, outside, and has a stem through-hole between two parties, has a stuffing box packing chamber on through-hole wall; That bottom and lower shell body combine as a whole, open the column construction of stem through-hole between two parties;

Spool-this spool is that a top is that taper, bottom are circular solid body, is centrally placed in the valve body upper shell;

Valve rod-this valve rod upper end combines as a whole with spool, passes valve body upper shell and valve body lower shell body between two parties;

Seal pressure cap-this pressure cap cover is positioned at the valve body lower shell body, and engage sleeves is loaded on the valve rod, and the upper end cooperates the insertion envelope to be pressed in the stuffing box packing chamber, and stuffing box packing is fixed; Seal pressure cap lower end edge end is fixed by vertical fixing bolt;

Fixed arm-this fixed wall is fixed on the valve body lower shell body bone wall, connects with seal pressure cap fixing bolt upper end.

A kind of taper discharging valve of the present utility model is characterized in that being provided with one handle in the valve rod lower end.

The utility model discharging valve can effectively solve the problem of solid-liquid mixture container blowing difficulty; Valve core is that top is the ellipsoid of cone, and wherein sealing surface is the ellipsoid part, is provided with liner rubber on the surface of contact of spool and valve body upper enclosure inner wall, and the envelope material is effective; Dispensing valve is installed in the container bottom of splendid attire solid-liquid mixture, and the blowing using effect is good.

Embodiment

A kind of taper discharging valve, this valve blowing is made up of following structure: this upper shell of valve body upper shell 1-is the spherical hollow space housing that a upper and lower part all has round breach, attached method orchid outside the upper and lower opening place of housing has respectively has drain hole and is connected with vomit pipe on the sidewall of housing; Be arranged circumferentially sheet rubber 2 on the spherical hollow space inner walls in the upper shed of housing; This housing of valve body lower shell body 3-is that the middle part is a spherical hollow space housing; Top is the flange arrangement that matches with valve body upper shell lower flange and connect of upwards flaring type that combine as a whole with lower shell body, outside, and has a stem through-hole between two parties, has a stuffing box packing chamber 4 on through-hole wall; That bottom and lower shell body combine as a whole, open the column construction of stem through-hole between two parties; This spool of spool 5-is that a top is that taper, bottom are circular solid body, is centrally placed in the valve body upper shell; This valve rod upper end of valve rod 6-combines as a whole with spool, passes valve body upper shell and valve body lower shell body between two parties; This pressure cap cover of seal pressure cap 7-is positioned at the valve body lower shell body, and engage sleeves is loaded on the valve rod, and the upper end cooperates the insertion envelope to be pressed in the stuffing box packing chamber, and stuffing box packing is fixed; Seal pressure cap lower end edge end fixes 8 by vertical fixing bolt; This fixed wall of fixed arm 9-is fixed on the valve body lower shell body bone wall, connects with seal pressure cap fixing bolt upper end; Be provided with one handle 10 in the valve rod lower end.

During use, the taper discharging valve is installed in the bottom of solid-liquid mixture, the pointed cone of spool partly inserts among the short tube of container blowing, when valve rod moves down, valve open, cone moves down, among container blowing short tube, form the space, solution flows down along the space, takes away the solid material in the short tube simultaneously, the difficulty the during tapping that solves the solid-liquid mixture material.
