Background technique
All kinds of flow control valves such as existing in the market widely used ball valve, needle-valve all do not have the pressure compensation spool, the effective pressure reduction control of can not entering, therefore common flow control valve in hydraulic system, can not stablize, control flow rate accurately.
The model utility content
The utility model is for providing a kind of simple and compact for structure, reliable, the stable flow rate modulating valve of single channel output flow.
The utility model is realized through following technical proposals:
A kind of flow control valve comprises throttling valve core, throttle valve valve body, valve core housing, pressure compensation spool, pressure spring and valve body joint, and said throttling valve core one end is located on the throttle valve valve body; The other end is provided with spiral cover and cover plate, and said valve body joint is connected with said throttle valve valve body, and it is inner that said pressure compensation spool is located at said valve core housing; And it is inner to be located at said throttle valve valve body and valve body joint with valve core housing; Said pressure spring one end and said pressure compensation spool are inconsistent, and the other end and said valve core housing are inconsistent, and said valve core housing one end is provided with input hole; The other end is provided with delivery outlet, and said pressure compensation spool is provided with opening.
Be provided with opening rotation Glais ring between said valve core housing and the said pressure compensation spool.
Between said throttle valve valve body and the said valve core housing, between said throttle valve valve body and the valve body joint, between said valve core housing and the said pressure compensation spool and said valve core housing end is equipped with the O RunddichtringO.
Be provided with circlip for hole, O type back-up ring and O type circle between said throttle valve valve body and the said throttling valve core.
Said spiral cover is connected with said throttle valve valve body with interior hexagonal cylinder Cock screw through the oval styletable Cock screw of slotting.
The beneficial effect that the utility model brought is:
In the utility model, said flow control valve has pressure compensation, makes the speed of executive component under hydraulic pump source changes in flow rate situation, keep constant, and does not change with load and variation of temperature, realizes the stable of single channel output flow; This kind flow control valve structure is simple, and cost is low, and system power dissipation is little, and efficient is higher, and is safe and reliable, and the scope that conforms is wide; In addition, manually just can accomplish and regulate and locking, easy to operate.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explain.
Fig. 1 is the sectional drawing of the said flow control valve of the utility model.
Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
The label that component names is corresponding among the figure is following:
1, throttling valve core; 2, throttle valve valve body; 3, valve core housing; 4, pressure compensation spool; 5, pressure spring; 6, valve body joint; 7, spiral cover; 8, cover plate; 9, input hole; 10, delivery outlet; 11, opening; 12, opening rotation Glais ring; 13, O RunddichtringO; 14, circlip for hole; 15, O type back-up ring; 16, O type circle; 17, the oval styletable Cock screw of fluting; 18, interior hexagonal cylinder Cock screw.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to detail:
As the embodiment of the said flow control valve of the utility model, as depicted in figs. 1 and 2, comprise throttling valve core 1, throttle valve valve body 2, valve core housing 3, pressure compensation spool 4, pressure spring 5 and valve body joint 6; Said throttling valve core 1 one ends are located on the throttle valve valve body 2; The other end is provided with spiral cover 7 and cover plate 8, and said valve body joint 6 is connected with said throttle valve valve body 2, and said pressure compensation spool 4 is located at said valve core housing 3 inside; And be located at said throttle valve valve body 2 and valve body joint 6 inside with valve core housing 3; Said pressure spring 5 one ends and said pressure compensation spool 4 are inconsistent, and the other end and said valve core housing 3 are inconsistent, and said valve core housing 3 one ends are provided with input hole 9; The other end is provided with delivery outlet 10, and said pressure compensation spool 4 is provided with opening 11.
In the present embodiment, be provided with opening rotation Glais ring 12 between said valve core housing 3 and the said pressure compensation spool 4.
In the present embodiment, between said throttle valve valve body 2 and the said valve core housing 3, between said throttle valve valve body 2 and the valve body joint 6, between said valve core housing 3 and the said pressure compensation spool 4 and said valve core housing 3 ends are equipped with O RunddichtringO 13.
In the present embodiment, be provided with circlip for hole 14, O type back-up ring 15 and O type circle 16 between said throttle valve valve body 2 and the said throttling valve core 1.
In the present embodiment, said spiral cover 7 is connected with said throttle valve valve body 2 with interior hexagonal cylinder Cock screw 18 through the oval styletable Cock screw 17 of slotting.
The working principle of said flow control valve is following:
When flow control valve was not worked, said pressure spring 5 withstood on throttle valve valve body 2 left sides with pressure compensation spool 4, and this moment is non-negotiable; The hydraulic oil of oil hydraulic pump output flows into from throttle valve valve body 2 left side ports, and through throttling valve core 1, this moment, pressure reduced to some extent; The pressure of hydraulic oil acts on pressure compensation spool 4 left ends, and along with the increase of input flow rate, pressure compensation spool 4 moves right; Hydraulic oil flows into from the input hole 9 of valve core housing 3, and through the opening 11 of pressure compensation spool 4, the delivery outlet 10 through valve core housing 3 flows out arrival valve body joint 6 again; When pressure reduction increases to certain numerical value, pressure reduction and spring force balance, then the stability of flow of output is on certain numerical value; When the flow of oil hydraulic pump continues to increase; Pressure compensation spool 4 can move right, and the aperture of the delivery outlet 10 of valve core housing 3 right-hand members is reduced, thereby make flow continue to keep stable.
