Abstract
The utility model relates to a hard-seal liquid flow control valve. The technical scheme adopted by the utility model is as follows: the hard-seal liquid flow control valve comprises a valve body, a valve seat, a valve core, an actuating mechanism and a coupling, wherein the coupling is in linkage with the valve core, the actuating mechanism can drive the coupling to rotate, and the valve core and the valve seat are coordinated to control the opening and closing of the control valve. The hard-seal liquid flow control valve is characterized in that a spring promoting the valve seat to be appressed to the valve core is arranged between the valve seat and the valve body. By adoption of the scheme, the utility model overcomes the defect in the prior art and provides the novel hard-seal liquid flow control valve with the advantages of simple structure, small required torque for opening and closing the valve, good sealing effect and long service life.
Description
Technical field
The utility model relates to a kind of hard seal fluid flow control valve.
Background technique
At present, the ball-valve structure that circulates on the market is basically all similar, has consisted essentially of valve body, valve gap, spool, valve seat and lining; It is main wherein pressing with sealing surface between spool and the valve seat; Some defectives below the ball valve of this structure exists: rotation torque is big, and power consumption is big, and working life is short.
Summary of the invention
The utility model overcomes the deficiency that existing technology exists, and provides a kind of simple in structure, and the valve opening and closing required torque is little, and consumed power is little, good sealing effect, the novel hard seal fluid flow control valve of long service life.
Realize above-mentioned purpose; The utility model adopts following technological scheme: a kind of hard seal fluid flow control valve; Include valve body, valve seat, spool, actuator and coupling piece, wherein coupling piece and spool are connected, and actuator can drive coupling piece and rotate; Cooperating the conducting that realizes control valve and closing of spool and valve seat is characterized in that: be provided with between said valve seat and the valve body and impel valve seat to be adjacent to the spring of spool.
Through adopting such scheme, the utility model can the chamber spool and valve seat between sealing effect better, stable work in work, most importantly valve seat can through spring remedy and spool between frictional loss, valve is increased the service life greatly.
The further setting of the utility model is: said valve seat is arranged on the valve body through its peripheral fixed block; This fixed block is arranged on the valve body through bolt; Between the inner side surface of this fixed block and the outer side surface of valve seat seal ring is set; Said valve seat is provided with the spring holding cavity away from an end of spool, and spring one end is conflicted in the bottom of holding cavity, and the other end is conflicted on valve body.
Further being provided with again of the utility model is: described actuator includes micromachine and speed reducer; Wherein minitype motor driving speed reducer work; The output shaft of speed reducer is connected on coupling piece; The downside of said valve body is provided with valve gap, and the spool lower end is rotated through bearing and is arranged on the valve gap, and said valve gap is arranged on the fixed block through bolt.
Through the scheme of above-mentioned further setting, make product structure more reasonable, particularly simpler on making, structure is more reasonable.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the utility model embodiment overall structure schematic representation.
Embodiment
As shown in Figure 1, a kind of hard seal fluid flow control valve includes valve body 1, valve seat 2, spool 3, actuator 4 and coupling piece 5; Wherein coupling piece 5 is connected with spool 3, and actuator 4 can drive coupling piece 5 and rotate, the cooperating the conducting that realizes control valve and close of spool 3 and valve seat 2; Above-mentioned technical characteristics also is common in the prior art, so we just have not been described in detail in the present embodiment, in the utility model embodiment; Be provided with between said valve seat 2 and the valve body 1 and impel valve seat 2 to be adjacent to the spring 6 of spool 3; Adopt such scheme, the utility model can chamber spool 3 and valve seat 2 between sealing effect better, stable work in work; Most importantly valve seat 2 can through spring 6 remedy and spool 3 between frictional loss, valve is increased the service life greatly.
In the utility model embodiment; Said valve seat 2 is arranged on the valve body 1 through its peripheral fixed block 7; This fixed block 7 is arranged on the valve body 1 through bolt, between the outer side surface of the inner side surface of this fixed block 7 and valve seat 2 seal ring 8 is set, and said valve seat 2 is provided with spring holding cavity 21 away from an end of spool 3; Spring 6 one ends are conflicted in the bottom of holding cavity 21, and the other end is conflicted on valve body 1; Described actuator 4 includes micromachine 41 and speed reducer 42; Wherein micromachine 41 drives speed reducer 42 work; The output shaft of speed reducer 42 is connected on coupling piece 5; The downside of said valve body 1 is provided with valve gap 9, and spool 3 lower ends are rotated through bearing and are arranged on the valve gap 9, and said valve gap 9 is arranged on the fixed block 7 through bolt.
