The utility model comprises a valve body, a clack seat and a seal ring, wherein, a restricted speed ring and an elastic body are arranged inside the valve body, the clack seat is screw-thread-enjoined with the valve body, flexibility of the elastic body is employed by the utility model to adjust the velocity of flow, thereby, the purpose of controlling the velocity of flow accurately can be achieved. The utility model is characterized in that the structure is simple, the manufacture is easy, the cost is low, the controlling accuracy is high, and the operation is convenient.
Description
Technical field
This utility model belongs to medical instruments field, relates to a kind of flow control valve that is mainly used in the scalable flow velocity in the clinical transfusion process.
Background technology
Be widely used in the transfusion device flow control valve in the transfusion at present, in infusion process, the pressure of input can reduce with the minimizing gradually of dose, and the pressure that enters the human vas place simultaneously moves with the position of human body again and changes, therefore, can't accurately control infusion flow.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, precision height, the flow control valve of scalable flow velocity easy and simple to handle.
This utility model is achieved in that a kind of flow control valve of scalable flow velocity, comprises valve body, valve seat, sealing ring, is provided with speed-limiting ring, elastomer in its valve body, valve seat and valve body spiral marking connection.Valve body top is arrival end, and the bottom is upper plenum and following cavity, and the speed-limiting ring that has aperture is arranged on down in the cavity, by seal ring seal.Be provided with the port of export in the valve seat.Upper plenum and following cavity are by two sealing rings separations up and down.The circumference axial or valve seat of valve body is provided with flow scale, and valve body is provided with pointer.Elastomer can be spring, elastic tubular body, Periostracum Serpentis tubular body.
This utility model adopts elastomeric extension and contraction control to regulate flow velocity, thereby realizes the accurately purpose of control infusion flow.This utility model is simple in structure, is easy to make, and cost is low, and the control accuracy height is easy and simple to handle, can extensively be suitable for various transfusion apparatuses and install and use.
Description of drawings
Fig. 1 is the exploded view of this utility model structural representation;
Fig. 2 is the installation diagram of this utility model structural representation.
The specific embodiment
Consult Fig. 1, shown in Figure 2, a kind of flow control valve of scalable flow velocity, mainly constitute by valve body 1, speed-limiting ring 2, sealing ring 3, elastomer 4, valve seat 5 etc., its valve body 1 is a column type, top is arrival end 101, the bottom is upper plenum 102 and following cavity 103, and the speed-limiting ring 2 that has aperture 201 is arranged on down in the cavity 103, by sealing ring 3 sealings; Elastomer 4 is arranged on down in the cavity 103, and elastomer 4 can select for use spring to be connected with speed-limiting ring 2, is provided with the port of export 501 in the valve seat 5, valve seat 5 and valve body 1 spiral marking connection, by sealing ring 3 sealings, two sealing rings 3 can be separated upper plenum 102 and following cavity 103 up and down, and prevent intravenous extravasation; At axially or on the circumference of valve seat 5 of valve body 1, be provided with flow scale, valve body 1 is provided with pointer.
Elastomer 4 of the present utility model also can select for use silicone rubber or plastic production to become elastic tubular body, Periostracum Serpentis tubular body etc.
Operation principle of the present utility model:
Liquid is entered by the arrival end 101 of valve body 1 in the transfusion device, enter aperture 201 in the speed-limiting ring 2 by upper plenum 102, the internal diameter of aperture 201 is the controlling unit of liquid flow in the valve, and the liquid by aperture 201 enters down cavity 103, enters port of export passage 501 then and flows out.Rotatable valve seat 5 when medical personnel operate makes valve seat 5 upper ends 502 reach the scale that will regulate flow, and perhaps rotary valve base 5, make pointed be engraved in the scale of the flow to be controlled of valve seat 5 circumferencial directions.
