Description
Technical field
The utility model relates to a kind of discharge modulating valve, belongs to material regulating valve technical field.
Background technique
Existing discharge modulating valve great majority comprise valve body, spool and valve gap, form cavity in the valve body, and valve body lower portion forms valve seat, and said spool passes cavity and places on the valve seat, and valve gap is fixed on the valve body, and valve seat links to each other with outside input duct.The valve seat of this discharge modulating valve is on valve body, to process retribution for evildoing; Can only disposablely use, can be stuck when spool secondary in having the medium of particle uses or locking and influence the normal operation of equipment, therefore; This discharge modulating valve can only disposablely use; It is very short press to leach on the high-pressure autoclave discharging pipe working life at oxygen, in addition two days less than, thereby cause the valve arrangement cost too high.
The model utility content
The utility model provides a kind of simple in structure in order to overcome the deficiency that existing technology exists, can nonexpondable discharge modulating valve.
The utility model can be achieved through taking following technological scheme:
A kind of discharge modulating valve; Comprise valve body, form a valve pocket that is provided with opening in spool, valve gap, valve gap pressing plate and the valve seat, said valve body; Said valve gap is fixed on the upper end of valve body through the valve gap pressing plate; Said valve seat is installed in the lower end of valve body and is communicated with valve pocket, and an end of said spool passes valve gap, and its other end passes valve pocket and is connected on the valve seat.
In order to make the structural stability of whole discharge modulating valve, the central lines of the said valve gap of the utility model, spool and valve seat.
On the basis of the above, the end that the said spool of the utility model contacts with valve seat is cone shape, and spool can well be connected on the valve seat, improves the degree of regulation of whole discharge modulating valve.
The said valve seat of the utility model makes to form vertical arrangement between the two perpendicular to valve pocket, makes things convenient for medium high in and low out operation.
The said valve seat flare of the utility model, its upper end is communicated with the bottom of valve pocket, and valve body is stretched out in its lower end, and through flared structure, pressure diminishes with the increase of pipeline when making the liquid material through valve seat, and minimizing liquid material connects the damage of equipment after to valve seat.
Be provided with pad between said valve gap of the utility model and the valve body, make the better tightness between valve gap and valve body.
The opening of the said valve pocket of the utility model is provided with pressure reducing orifice, is used to adjust the pressure of liquid in the valve pocket.
The said spool of the utility model stretches out a termination of valve gap and suppresses structure, is used for the interlock spool, spool can be moved up and down, in order to the flow of modulating valve intraluminal fluid material.
Compared with prior art; The beneficial effect of the utility model is: the valve seat of the utility model is installed in the lower end of valve body and is positioned at the valve pocket below; Valve seat and valve body adopt separable setting; Spool can be changed with valve seat under the situation of stuck or locking, and the discharge modulating valve can be reused, thereby has reduced the operating cost of discharge modulating valve equipment.
Description of drawings
Fig. 1 is the structural representation of the discharge modulating valve of the utility model.
Embodiment
Below in conjunction with accompanying drawing the most preferred embodiment of the utility model is described in detail.
As shown in Figure 1, the discharge modulating valve of the utility model comprises valve body 1; Spool 2, valve gap 3, valve gap pressing plate 4 and valve seat 5; Form a valve pocket 6 that is provided with opening in the said valve body 1, said valve gap 3 is fixed on the upper end of valve body 1 through valve gap pressing plate 4, and said valve seat 5 is installed in the lower end of valve body 1 and is communicated with valve pocket 6; One end of said spool 2 passes valve gap 3, and its other end passes valve pocket 6 and is connected on the valve seat 5.
The central lines of the said valve gap of the utility model 3, spool 2 and valve seat 5 can make the structural stability of whole discharge modulating valve.
The end that the said spool 2 of the utility model contacts with valve seat 5 is cone shape, and spool 2 can well be connected on the valve seat, improves the degree of regulation of whole discharge modulating valve.
The said valve seat 5 of the utility model makes to form vertical arrangement between the two perpendicular to valve pocket 6, makes things convenient for medium high in and low out operation.
Said valve seat 5 flares of the utility model, its upper end is communicated with the bottom of valve pocket 6, and valve body 1 is stretched out in its lower end, the through port flared structure, pressure diminishes with the increase of pipeline when making the liquid material through valve seat 5, and minimizing liquid material connects the damage of equipment after to valve seat 5.
Be provided with pad 7 between said valve gap 5 of the utility model and the valve body 1, make between valve gap 5 and valve body 1 better tightness.
The opening of the said valve pocket 6 of the utility model is provided with pressure reducing orifice 8, is used to adjust the pressure of valve intraluminal fluid material.
The said spool 2 of the utility model stretches out a termination of valve gap 3 and suppresses structure 9; This suppresses structure 9 and comprises and suppress cylinder 91, pressing plate 92 and spring 93; Said pressing plate 92 places and suppresses cylinder 91; Said spool 2 passes the bottom of suppressing cylinder 91 and is connected on the pressing plate 92, and the two ends of said spring 93 are connected on pressing plate 92 respectively and suppress on the top of cylinder 91, like this during suppressing structure 9 from down and formation air and spring dual regulation; Spool can be moved up and down, in order to the flow of modulating valve intraluminal fluid material.
