Problems solved by technology

[0009] The purpose of the present invention is to provide a concentric flow regulator that does not change the shape of the streamline bundle of the water sample, so as to solve the problem that the sample is distorted due to the precipitation of volatile and semi-volatile substances in the polluted water sample caused by the deformation of the streamline bundle

Embodiment Construction

[0020] like figure 1 , figure 2 As shown, the concentric flow regulator of the present invention has an axial core hole in a straight handle-shaped handle 3, and the sampling hose 1 is threaded through the core hole, and the rod body of the handle 3 is provided with a core The horizontal rope-passing hole connected by the hole is provided with a rotating shaft rope tightener 2 wound with a fastening rope on the grip bar 3 at the outer port of the rope-passing hole, and the fastening rope 20 drawn from the rotating shaft rope tightener 2 is passed through After the rope hole on the grip bar 3, its end is fixed on the grip bar 3.

[0021] The fixing method of the end of the fastening rope 20 is to open a slit tangent to the edge of the core hole on the upper end surface of the grip bar 3, the depth of the slit reaches the height of the rope hole, and the end of the fastening rope 20 is embedded connected and fixed in this slit on the grip bar 3 ( Figure 4 ); the second is t...

Abstract

The invention relates to a concentric flow regulator which adopts the following structure that an axial core hole for allowing a sampling hose to be inserted and a transverse rope through hole communicated with the core hole are formed in the rod body of a holding rod; a rotating shaft rope tightener for winding a fastening rope is arranged on the holding rod and in a position at the outer end opening of the rope through hole; after the fastening rope drawn from the rotating shaft rope tightener passes through the rope through hole in the holding rod and enters the core hole, the end part of the fastening rope is fixed on the holding rod; the fastening rope surrounds the inserted sampling hose by a circle in the core hole of the holding rod. The concentric flow regulator achieves ring-type binding regulation of the fastening rope on the sampling hose, achieves the purpose of concentric flow regulation and enables the flow line beam of water passing through the sampling hose to be cylindrical always so as to reduce probability of separating out volatile and semi-volatile substances in a polluted water sample and improve the fidelity of the sample.

Description

technical field [0001] The invention relates to a flow regulating device, in particular to a concentric flow regulator. Background technique [0002] At present, the adjustment methods of liquid flow mainly include contact flow adjustment and non-contact flow adjustment. [0003] Contact flow adjustment, such as various valves, the flow adjustment device is in direct contact with the liquid, and the quality of the liquid flowing through it is easily affected by the flow adjustment device; on the other hand, the streamline bundle of the liquid entering and leaving the flow adjustment device changes greatly. It cannot meet the requirements for flow adjustment when collecting samples containing volatile and semi-volatile substances that require stable liquid streamline bundles. [0004] Non-contact flow regulation is to control the flow by changing the pipe diameter of the pipeline that transports the liquid. The common way is "squeezing", such as various pipe clamps, and the ...
