Model utility content
The utility model object is in order to overcome the deficiencies in the prior art, and a kind of reinforced electric ball valve of automatically controlling is provided, and it can be by ball valve is controlled, thereby realize the speed control to adding raw material, guarantees the controllability to adding raw material process.
In order to achieve the above object, the utility model is by the following technical solutions:
A kind of electric ball valve that feeds in raw material of automatically controlling, comprise ball valve shell, there is the valve seat of valve pocket, the first control device that is embedded the spool in described valve pocket and is connected with described spool, described spool has the main flow hole that level connects, and is also provided with the first discharge orifice and the second discharge orifice that level connects in described spool; Described the first discharge orifice, the second discharge orifice and main flow hole three form 60 degree mutually, and described the first discharge orifice and the second discharge orifice and main flow hole are in same plane; The aperture of described the first discharge orifice is less than main flow hole, and the aperture of described the second discharge orifice is less than the first discharge orifice; On described valve seat and position seal spool, be provided with seal ring, described seal ring is fixed on valve seat; Described first control device is electric controller.
As preferably, described valve seat is made up of interior valve seat, main valve seat and outer seat, is loaded three mutual relatively independent movements of valve seat between each valve seat by loading spring separately.
As preferably, the material of described outer seat and interior valve seat is metal, and described main valve seat is macromolecule polymer material.
As preferably, described seal ring is topping up inflatable seal circle, and described topping up inflatable seal circle comprises seal ring body, and seal ring body inner side is provided with topping up chamber, and described topping up chamber is communicated with liquid-transport pipe-line.
As preferably, described control arm is connected with electric controller, and described electric controller is used for controlling control arm and rotates.
Compared with prior art, the utlity model has following beneficial effect:
By said structure, adding in raw material process, can be by ball valve is controlled, thus realize the speed control to adding raw material, guarantee the controllability to adding raw material process; Seal ring and three layers of this two kinds of sealing configurations of valve seat construction auxiliary sealing that can improve ball valve mutually, than the effect excellence of single sealing configuration; Ball valve integrated operation is convenient, and practicability is high, very reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure:
1-ball valve shell; 2-valve seat; 21-interior valve seat; 22-main valve seat; 23-outer seat; 3-spool; 31-main flow hole; 4-seal ring; 5-fluid line.
Now the utility model is described in further detail with specific embodiment by reference to the accompanying drawings.
Embodiment
As shown in Figure 1, for the reinforced electric ball valve of automatic control described in the utility model, comprise ball valve shell 1, there is the valve seat 2 of valve pocket, the first control device that is embedded the spool 3 in described valve pocket and is connected with spool 3.Wherein, first control device is used for driving spool 3 to rotate in valve pocket, controls the unlatching of this ball valve or closes, and first control device adopts electronic control mode to drive spool 3 to rotate, and first control device is connected with automatic control system communication.First control device can be cylinder.
Spool 3 has the main flow hole 31 that level connects, and is provided with the first discharge orifice and the second discharge orifice that level connects; The first discharge orifice, the second discharge orifice and main flow hole 31 threes form 60 degree mutually, and the first discharge orifice and the second discharge orifice and main flow hole are in same plane.The aperture that the aperture of the first discharge orifice is less than main flow hole 31, the second discharge orifices is less than the first discharge orifice.Three discharge orifices are wherein when the positive convection cell of discharge orifice pipeline 5, and sidewall and both apertures of other two discharge orifice steering ball valve chests 1 are arranged on the seal ring seal on ball valve shell 1.
Application of the present utility model:
Realize and control the unlatching of ball valve and close by first control device; When normal interpolation raw material process, the positive convection cell pipeline in main flow hole, flowing medium only flows out ball valve by main flow hole; In the time that needs slow down interpolation feed rate, by first control device, Spool rotating 60 to be spent, fluid line is just to the first discharge orifice, and flowing medium only flows out ball valve by the first discharge orifice, and the flow of flowing medium reduces, and adds feed rate reduction; In the time that needs further slow down interpolation feed rate, with same direction mentioned above, spool is rotated to 60 degree by first control device edge again, fluid line is just to the second discharge orifice, be that flowing medium only flows out ball valve by the second discharge orifice, the flow of flowing medium further reduces, and adds feed rate and further reduces.
Three layers of valve seat are not an entirety mutually, are Spielpassung each other.Axially can be relatively freely movable; under the effect of loading spring and pressure medium separately; interior valve seat, main valve seat and outer seat can contact spool sphere simultaneously; main valve seat plays main seal action; when its auxiliary seal effect of interior valve seat and outer seat; particle in block media enters between spool sphere and main valve seat, thereby plays the object of protection main valve seat sealing surface.
When spool is in the time closing valve position, means for indicating valve conditions to the instruction of sealing controller to make to be full of rapidly liquid in seal ring chamber, regardless of spool quality, can realize good sealing effect; In the time that spool need to be opened, means for indicating valve conditions is given the instruction of sealing controller, makes rapidly seal ring venting, and seal ring leaves spool face at once, when valve core rotation and between valve, does not have friction, has extended the working life of correct ball valve.
The utility model is not limited to above-mentioned mode of execution, if various changes of the present utility model or modification are not departed to spirit and scope of the present utility model, if within these changes and modification belong to claim of the present utility model and equivalent technologies scope, the utility model is also intended to comprise these changes and variation.
