Abstract
The utility model discloses a liquid flow control valve, solving current defect that bigger noise shall exist when fluid passes through a port for liquid which is arranged on the valve base during the liquid flow control valve using. Technic proposals adopted are: a liquid flow control valve, comprising a cylinder-shaped valve base and a valve rod which is arranged inside the valve base; said valve base is provided with the through port for liquid, inner end of said valve rod is inserted into the valve base and connects a movable valve clack which is provided with an upper nick at the lower surface, inside the valve base and the lower side of the movable valve clack are provided with fixing valve clacks which is fixed circumferentially at the valve base, upper surface of the fixing valve clack is provided with a lower nick, said upper and lower nick correspond to the place of the through port for liquid on the valve base along the axis direction of the valve base. The utility model relates characterized in that: the upper nick for said movable valve clack is provided with a muffler, which has certain elastic.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of liquid flow control valve.
Technical background
In daily life and producing, many liquid all need to transmit by pipeline, generally all need be provided with liquid flow control valve on pipeline, in order to the flow of controlling liquid and close and break-make.The structure of existing liquid flow control valve comprises valve seat, is located at the valve rod in the valve seat, the inner of valve rod is inserted in the valve seat, and be connected with a movable flap on the inner of valve rod, the downside of movable flap is provided with fixedly flap in valve seat, wherein the lower surface of movable flap is provided with breach, fixedly the upper surface of flap is provided with breach, described upper and lower breach valve seat on axially the position and valve seat on the position of fluid-through port corresponding.Fixedly flap is circumferentially fixing with respect to valve seat, and when pulling the outer end of valve rod, the movable flap that is connected on valve rod the inner can be followed valve rod and be rotated together, like this staggering and the overlapping control that realizes fluid flow by upper and lower gap position.Existing flow control valve in use because the pressure of liquid own is higher, when liquid can form stronger eddy current during by liquid outlet herein, thereby can produce bigger noise at the fluid-through port place of valve seat.
Summary of the invention
For overcoming the above-mentioned defective of existing liquid flow control valve, the utility model technical issues that need to address are: a kind of new liquid flow control valve is provided, it in use can reduce the noise that the fluid-through port place produces on the valve seat effectively, and single between structure, do not have influence on the normal use of control valve.
For solving the problems of the technologies described above, the technical solution of the utility model: a kind of liquid flow control valve, comprise valve seat cylindraceous, be located at the valve rod in the valve seat, described valve seat is provided with fluid-through port, the inner of described valve rod inserts in the valve seat, be connected with movable flap on the inner of valve rod, the lower surface of this activity flap is provided with breach, in valve seat, the downside of movable flap is provided with the fixedly flap circumferentially fixing with respect to valve seat, fixedly the upper surface of flap is provided with down breach, on described, following breach valve seat axially on valve seat on the position of fluid-through port corresponding, it is characterized in that, indentation, there is provided with baffler on the described movable flap, and this baffler has certain elasticity.Have certain flexible baffler a buffer function can be arranged the liquid that flows through fluid-through port, slow down the rapid degree of liquid, when flow of liquid is crossed fluid-through port on the valve seat, be difficult for causing noise because of resonance phenomenon at the fluid-through port place.
As preferably, described baffler roughly is " ∏ ", and it is connected between the inner and movable flap of valve rod, and the part that this baffler extend into indentation, there on the movable flap is provided with some Cylindrical objects arranged side by side.Be provided with the Cylindrical object of plurality of parallel, little to the flow rate effect of liquid in the control valve, caused noise when simultaneously also having reduced flow of liquid effectively and crossing fluid-through port on the valve seat.
As preferably, the V-shaped arrangement in the outer end of described some Cylindrical objects.The V-shaped arrangement in the outer end of Cylindrical object meets principle of hydrodynamics.
As preferably, described baffler and Cylindrical object are connected as a single entity.Baffler and Cylindrical object are generally integrated injection molding, and speed of production is fast, and Cylindrical object and baffler connectivity robustness are good.
As preferably, describedly go up breach, breach is fan-shaped down.Upper and lower breach is fan-shaped, is convenient to fluid and passes through apace.
Therefore, the beneficial effects of the utility model:
In control valve, be provided with on the movable flap and have certain flexible baffler, can have certain buffer function to the liquid that flows through fluid-through port place on the valve seat, make the liquid at fluid-through port place on the valve seat be difficult for the more rapid eddy current of shape, reduced the noise that liquid causes in described fluid-through port place effectively.And simple in structure, easy for installation, little to the influence of the flow rate of liquid in the control valve.
