still including can be at the measuring part of extension intraductal flexible, the front end of measuring part is provided with the measuring head, works as when measuring the inside front end terminal surface of a front end terminal surface and extension pipe and when laminating, form an unblocked flow field between the shell body of extension pipe, the shell body of measuring part and the measured flow channel, and the measuring head is arranged in this flow field.

In the measuring device applied to the fluid in the pipeline, the rear end of the bottom plate is fixedly connected with the cleaning section, the outer shell of the cleaning section is provided with a cleaning hole, and the cleaning hole of the measuring piece is communicated with the cavity where the measuring head is located in the telescopic part process.

In the measuring device applied to the fluid in the pipeline, the outer shell of the measuring part is embedded with the sealing ring, and the sealing ring is always tightly connected with the inner side wall of the cleaning section in the telescopic process of the measuring part.

In the measuring device applied to the fluid in the pipeline, the rear end of the measuring part is connected with the hydraulic cylinder, and the hydraulic cylinder provides power for stretching and retracting the measuring part.

The utility model has the advantages that: the utility model discloses set up an extension pipe at the bottom plate front end, when measuring in as for the extension pipe, both can realize measuring function, can guarantee again that the foremost casing of measuring does not receive fluidic erosion.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Example (b): referring to fig. 1, the device mainly comprises three parts: mounting part: the extension pipe comprises a bottom plate 6 and an extension pipe 1 fixedly arranged at the front end of the bottom plate 6, wherein the front section of the extension pipe is of a solid structure, the rear end of the extension pipe is of a hollow opening structure, and the opening penetrates through the bottom plate 6; in addition, through holes 2 (two communicated with each other) are separately provided in the housing portion of the hollow portion; when the part is placed in the measuring pipe, the fluid in the pipe flows out through the through hole 2 in the housing.

And the cleaning section 7 is a hollow part fixedly connected to the rear end of the bottom plate 6, and the cleaning section 7 is communicated with the extension pipe 1. The shell of the cleaning section 7 is provided with cleaning holes 71 (two communicated with each other), wherein one cleaning hole is connected with the liquid outlet end of the cleaning agent, and the other cleaning hole is connected with the recovery end of the cleaning agent.

The measuring element 4 for measuring, which is exemplified by a ph meter in the present embodiment, is specifically configured as shown in fig. 3, and is provided with a measuring head 41, the measuring head 41 is located in a cavity, and two oblong holes 3 are formed in a housing of the cavity;

a sealing ring 42 is fixedly embedded on the outer side wall of the measuring part 4.

The rear end of the measuring part 4 is connected with a hydraulic cylinder 5, a double-head hydraulic cylinder specific installation structure can be adopted, as shown in figure 1, and the hydraulic cylinder 5 provides power for the extension and retraction of the measuring part 4.

The working principle is as follows: continuing to refer to fig. 1, the state of fig. 1 is actually the state that the measuring head in the measuring part 4 is cleaned, the oblong hole 3 and the cleaning hole 71 in the figure are butted to form a cleaning flow field, cleaning agent is injected from one cleaning hole 71 and washes the measuring head 41 through the oblong hole 3, and finally the cleaning agent is output through the oblong hole 3 and the cleaning hole 71 at the other end; until the cleaning is finished. In the process, the rear end of the cleaning piece 4 is kept sealed with the inner wall of the cleaning section 7 through the sealing ring 42, so that the cleaning agent is prevented from flowing out; the front end of the cleaning piece 4 is in sealing sliding connection with the cleaning section 7 to realize leakage prevention, and a sealing ring can be installed on the front end of the cleaning piece, so that in practical application, leakage is difficult to cause even if the sealing ring is not installed, because a flow passage formed by the cleaning hole 71 and the long round hole 3 is smooth enough, and even if part of residual or leakage flows into a pipeline, the influence can be almost omitted;

after cleaning, pushing the measuring part 4 into the extension pipe 1 through the hydraulic cylinder 5, when the front end face of the measuring part 4 is attached to the inner end face of the extension pipe 1, communicating the through hole 2 with the oblong hole 3, and at the moment, allowing fluid in the pipeline to enter a cavity where the measuring head 41 is located, and performing measuring work by the measuring head; at this time, the outer wall of the front end of the measuring part 4 does not substantially contact the fluid in the pipe, so that erosion is avoided, and as can be seen from fig. 1, when measuring, the foremost end and the rear end (the part having the sealing function) of the measuring part do not substantially contact the fluid to be measured, so that the service life can be greatly prolonged.
