Description

Flow limiting tube

Technical Field

The utility model relates to a technical field is injectd to waste water flow proportion specifically is flow limiting pipe.

Background

The flow limiting pipe is also called as a 'fluid flow ratio limiting valve', is commonly called as a 'wastewater ratio' because the flow limiting pipe is commonly used for controlling the wastewater discharge ratio in a water purifier, the flow in a pipeline is limited by an internal capillary needle, and the external of the flow limiting pipe can be conveniently connected into various pipelines in a quick connection structure mode, so that the flow limiting pipe is widely used for controlling the wastewater flow in the reverse osmosis machine water purifier to achieve the effects of water saving and throttling.

Waste water on the current market is more mainly than using ABS as the main material, through purpose-made glue with each part bonding together, if beat the volume of gluing not enough, probably lead to the product degree of adhesion to hang down excessively, the condition that leaks or the bearing capacity is not enough appears, if beat the volume of gluing too much, it is excessive and probably corrode the product surface to appear glue easily, it is bad to use the product outward appearance, product volume is too big simultaneously, be unfavorable for customer's production installation, in view of this, need develop a simplified structure, small in size does benefit to the product of assembly, for this reason, we provide the flow limit pipe.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a flow limiting pipe to solve the problem of proposing among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: flow limiting tube, including main part, case and inner jaw, the main part includes left end portion, coupling end and right-hand member portion, the case includes needle hub and capillary needle, the capillary needle inlays and establishes the one side end that is located the needle hub and is close to the left end portion, set up the jack with capillary needle looks adaptation on the needle hub, the needle hub inlays and establishes the inside that is located the left end portion, set up the mounting groove with needle hub looks adaptation on the left end portion, the one side that the left end portion was kept away from to the needle hub and the one side end that coupling end portion was kept away from to the right-hand member portion all inlay and be equipped with the inner jaw, all set up the spread groove with inner jaw looks adaptation on needle hub and the right-hand member portion.

Furthermore, the front surface of the connecting end part is in a shape of a water bottle which is transversely arranged, the connecting end part is communicated with the right end part through a communication hole, and the communication hole is arranged in the main body.

Further, the left end portion and the right end portion are identical in size and shape.

Further, the connecting groove, the inserting hole and the main body are communicated.

Furthermore, a sealing ring is arranged between the needle sleeve seat and the inner claw in a supporting mode, and the sealing ring is sleeved on the outer surface of the inner claw.

Compared with the prior art, the beneficial effects of the utility model are that:

1. through setting up the main part, the needle hub seat, the capillary needle, sealing washer and inner jaw, through being big or small both ends with the main part design, can ensure that the assembly direction is correct, needle hub seat and capillary needle can assemble into the case, can press in the case to the great end of main part, through the common mating action of needle hub seat, the capillary needle, the sealing washer, inner jaw and main part, can make this device form the product that accomplishes fast and connect the structure fast, be convenient for according to the interior fluid flow direction of runner and insert, after this device inserts the runner, because capillary needle pipe diameter is less, the fluid is followed the input and is got into the restriction of back by the pipe diameter and make output flow diminish and satisfy the machine design needs, through the capillary needle of selecting different specifications, can assemble into the waste water ratio of different flow for the selection simultaneously.
