Abstract
The utility model relates to an adjustable jet-flow proportioning pump, which is composed of a pump main body and an internal nozzle; the internal part of the pump main body is provided with internal threads; the internal nozzle is an independent body; external threads are arranged at the external part of the internal nozzle; the internal nozzle is assembled at the internal part of the pump main body; the position of the internal nozzle at the internal part of the pump main body can be regulated by threads; a needle valve can be assembled at the internal part of a branch tube. The utility model has the advantages that according to actual demands, the utility model can regulate the position of the internal nozzle at the internal part of the pump main body to regulate the proportion between mainstream fluid and branch fluid.
Description
The utility model belongs to Jet injector, particularly a kind of adjustable jet dosing pump of adjustable flow ratio.
Present existing Jet injector is by the mobile negative pressure that forms of the fluid of power stream, extracts the fluid pump of the fluid on the arm.But the ratio between the main flow fluid of the power stream of same Jet injector and the tributary fluid that extracted by arm is certain, can not change.Therefore can not regulate the ratio between main flow fluid and the tributary fluid according to actual needs.
The purpose of this utility model provides a kind of adjustable jet dosing pump, overcomes the shortcoming and defect that above-mentioned Jet injector can not be regulated ratio between main flow fluid and the tributary fluid according to actual needs.
The purpose of this utility model is achieved in that
A kind of adjustable jet dosing pump is made up of the arm and the inner nozzle of pump main body, pump main body one side, and it is characterized in that: a side of pump body interior inlet side has internal thread; Inner nozzle is a separate component, and its inside is conical internal cavity, and outside thread is arranged outside it; Inner nozzle is assemblied in the pump body interior by outside thread the internal thread position, and can be by the threaded adjusting inner nozzle in pump body interior position.
The screw edge of a knife is arranged on the end face of the inlet side of inner nozzle.
The inside of arm can be equipped with needle-valve.
The needle inside of needle-valve is hollow, and its hollow space leads to the needle outside from the needle bottom, and as liquid entering hole, and its hollow space leads to the needle outside from the hole of needle sidepiece.
The valve inner of needle-valve has internal thread, and there is outside thread the outside of needle, and needle is through the inside of screw fit at valve body, and there is O-ring seal the needle outside, and in valve body, the needle O-ring seal has annular knurl outside the bottom with the needle top seal.
But the part of valve body pump main body one side branch of needle-valve.
The utility model has the advantages that:
This is adjustable, and the jet dosing pump can be regulated inner nozzle in the position of pump body interior according to actual needs, reaches the ratio of regulating between main flow fluid and the tributary fluid.
Below in conjunction with description of drawings embodiment:
Fig. 1 is adjustable jet dosing pump schematic representation
A kind of adjustable jet dosing pump has pump main body 1, pump main body one side to connect drawing liquid arm 2, and inner nozzle 3 is separate components, and its inside is conical internal cavity, and outside thread is arranged outside it; One side of pump body interior inlet side has internal thread; Inner nozzle is assemblied in the pump body interior by outside thread the internal thread position.The screw edge of a knife 4 is arranged on the end face of the inlet side of inner nozzle.And can be by the threaded adjusting inner nozzle in pump body interior position.
The inside of arm also can be equipped with needle-valve 5.The valve body of needle-valve can be an one with the drawing liquid arm, and promptly the valve pocket of needle-valve is in the drawing liquid arm.Needle 6 inside of needle-valve are hollow, and its hollow space 7 is from needle bottom and needle exterior, and its hollow space leads to the needle outside as liquid entering hole from the hole 8 of needle sidepiece.The valve inner of needle-valve has internal thread 9, and there is outside thread 10 outside of needle, and needle is through the inside of screw fit at valve body, and there is O-ring seal 11 the needle outside, and in valve body, the needle O-ring seal has annular knurl 12 outside the bottom with the needle top seal.
