Abstract
The invention relates to a novel black water adjusting valve, comprising a valve base (4), a valve body (2) and a valve back flange (5), wherein the valve body (2) and the valve back flange (5) are mounted on the valve base (4). The novel black water adjusting valve is characterized in that: a medium runner in the valve body (2) is linear; a valve core (7) is mounted in the runner; the valve core (7) is provided with a sealing table matched with an inlet of the valve base (4); connecting rods (3) are respectively fixed at the both sides of the valve core (7); and the other ends of the two connecting rods (3) are respectively connected with output shafts of two actuating mechanisms (1), so that the output shafts of the two actuating mechanisms (1) drive the valve core (7) to move along the medium runner to open or close the valve through linear motion. The adjusting valve provided by the invention is particularly suitable for the field of a coal chemical industry, enables medium to flow smoothly through the driving of the two coal chemical industries and the through way type runner, and reduces the damages of the medium on the valve base (4) and a pipeline, so that the service life of the valve is prolonged.
Description
Technical field
The present invention relates to a kind of novel Heisui River modulating valve.
Background technique
Existing Heisui River modulating valve valve body is big curved neck formula (referring to accompanying drawing 1), and after medium got into valve body, the flow direction of medium was vertical with the moving direction of spool, and impact force acts directly on valve rod and the spool, causes vibration and destruction; Simultaneously because the wide-angle of runner turns to, make medium produce very big centrifugal force, the pipeline (referring in accompanying drawing 1 mark A place) of side direction after to valve seat and valve washes away seriously.
Summary of the invention
The purpose of this invention is to provide a kind of novel Heisui River modulating valve, can eliminate the centrifugal force of medium, slow down medium to valve seat and valve after the washing away of pipeline.
A kind of novel Heisui River modulating valve; Comprise valve seat; And be installed in valve body and the valve rear flange on the valve seat; Its specialization is: the medium runner in the said valve body is a straight line type, in this runner, spool is installed, and on this spool, is provided with the sealing platform that cooperates with said valve seat inlet; Be fixed with a connecting rod separately in these spool both sides, move along the medium runner direction and open or throttle down thereby the other end of these two connecting rods is connected straight line moving belt movable valve plug through two actuator shafts respectively with the output shaft of two actuators.
Wherein two actuators are installed in the both sides of valve body respectively.
Wherein two actuators are pneumatic diaphragn actuating mechanism.
Thereby the guide sleeve that cooperates with spool wherein also is installed in valve body to play the guiding role.
Thereby wherein on spool, vertically be provided with at least one pod apertures and supply the medium circulation.
Wherein pod apertures is two, and is symmetrically distributed along valve core axis.
Modulating valve of the present invention is specially adapted to coal chemical technology, adopts the driving of two actuators, straight-through type flow passage to make media flow smooth and easy, thereby reduced medium has improved valve to valve seat and pipeline destroyed working life.
Description of drawings
Accompanying drawing 1 is the structural representation of background technique among the present invention;
Accompanying drawing 2 is a structural representation of the present invention;
Accompanying drawing 3 is the sectional view of spool (7) among the present invention;
Accompanying drawing 4 is the plan view of spool (7) among the present invention.
Embodiment
Like Fig. 2,3, shown in 4; A kind of novel Heisui River modulating valve; Comprise valve seat 4, and be installed in valve body 2 and valve rear flange 5 on the valve seat 4, the medium runner in the said valve body 2 is a straight line type; Spool 7 is installed in this runner; On this spool 7, be provided with the sealing platform that cooperates with said valve seat 4 inlets (among Fig. 3 spool 7 below locate), be fixed with a connecting rod 3 in these spool 7 both sides separately, move along the medium runner direction and open or throttle down thereby the other end of these two connecting rods 3 is connected straight line moving belt movable valve plug 7 through two actuator's 1 output shafts respectively with the output shaft of two actuators 1.
Wherein two actuators 1 are installed in the both sides of valve body 2 respectively, and two actuators 1 are many springs pneumatic diaphragn actuating mechanism, and are in light weight, volume is little, ouput force is big.Thereby supply the medium circulation and on spool 7, vertically be provided with at least one pod apertures, as shown in Figure 4, pod apertures is specially two, and is symmetrically distributed along spool 7 axis.As shown in Figure 2, thereby also being installed, the guide sleeve 6 that cooperates with spool 7 outer surfaces plays guiding and position-limiting action in valve body 2.
The present invention adopts two actuators 1 to drive, and makes before the valves, the flow direction behind the valve is consistent.Effectively improved the flow field, dielectric distribution is even on the one hand, and the regionality wearing and tearing of concentrating reduce, and has weakened the impact of medium to spool 7 and valve rod simultaneously.
