Abstract
The invention provides a device and method for detecting breakage of a delivery pipe. The device comprises an outer wall pipe and an inner wall pipe, wherein the inner wall pipe is located in the outer wall pipe, a middle area formed between the outer wall pipe and the inner wall pipe is filled with filling liquid, a plurality of pressure sensors are further arranged in the middle area, the two ends of the middle area are closed, and the pressure sensors are connected with an external monitoring system. The method includes the following operation steps: (1) reading a monitoring value P0 of the nth pressure sensor in the state that the inner wall pipe is empty; (2) filling the inner wall pipe with liquid or paste materials, closing the two ends of the inner wall pipe, exerting a certain pressure P1 on the liquid or the paste materials in the inner wall pipe, and reading a monitoring value P2 of the nth pressure sensor at the moment; (3) comparing the value P0 with the value P2, wherein if the P2 is greatly changed relative to the P0, it is indicated that the inner wall pipe is broken, and if the P2 is basically not changed relative to the P0, it is indicated that the inner wall pipe is not broken.

Technical field
The invention belongs to fluid foods conveyance conduit detection field, it is related to a kind of conveyance conduit damage detection device and side
Method.
Background technology
In existing fluid stream conveyance conduit detection field, the detection method of piping failure is mainly current gradient inspection
Survey, need manually or machinery is along pipeline survey, there is no a kind of reliable dynamic realtime monitoring method, particularly buried in underground
Tens meters, even hundreds of meter of conveyance conduit.
Content of the invention
Present invention aims to the problem that prior art exists, provide that a kind of structure is simple, reliable one
Plant conveyance conduit damage detection device.
Another object of the present invention is to providing a kind of method simple conveyance conduit damage testing method.
For this reason, the present invention adopts the following technical scheme that
A kind of conveyance conduit damage detection device, including outer wall pipe and inner wall tube, described inner wall tube is located in outer wall pipe, institute
State in the zone line being formed between outer wall pipe and inner wall tube and be filled with filling liquid, if being also laid with dry-pressing in described zone line
Force snesor, the closed at both ends of described zone line, described pressure sensor connects external monitoring system.
Further, described filling liquid is liquid or paste body shape material.
A kind of conveyance conduit damage testing method, using above-mentioned detection device, and includes following operating procedure:
(1) in the state of inner wall tube is sky, read the monitor value p0 of n-th pressure sensor with external monitoring system；
(2) fill liquid or pasty masses in inner wall tube, and close inner wall tube two ends, to the liquid in inner wall tube
Material or pasty masses apply certain pressure p1, read the monitor value p2 of now n-th pressure sensor with external monitoring system；
(3) compare the size of p0 and p2 value, if p2 occurs large change with respect to p0, illustrate that inner wall tube is damaged, such as base
Originally it is not changed in, then inner wall tube does not have breakage.
Further, confirm that inner wall tube does not have after breakage in the quiescent state by step (1) to (3), action is entered to inner wall tube
State real-time monitoring, particularly as follows: the conveying of inward wall pipe has the fluid of certain flow rate, reads the prison of n-th pressure sensor in real time
Measured value p3, if the numerical value of p3 is relatively stable always, inner wall tube is not damaged；As p3 value is substantially increased, then breaking occurs in inner wall tube
Damage；As p3 value is fallen after rising, then inner wall tube and outer wall pipe are all damaged.
The beneficial effects of the present invention is: apparatus of the present invention structure is simple, reliable；The inventive method is simple and easy to do,
Reliable results, the dynamic realtime monitoring of achievable conveyance conduit, particularly to buried in tens meters of underground, even hundreds of meter defeated
Send pipeline great suitability.

Value p2；
(3) compare the size of p0 and p2 value, if p2 occurs large change with respect to p0, illustrate that inner wall tube 2 is damaged, such as base
Originally it is not changed in, then inner wall tube 2 does not have breakage.
(2) dynamic detection
Confirm that inner wall tube 2 does not have after breakage in the quiescent state by step (1) to (3), dynamic realtime prison is carried out to inner wall tube 2
Survey, particularly as follows: inward wall pipe 2 conveying has the fluid of certain flow rate, read the monitor value p3 of n-th pressure sensor in real time,
If the numerical value of p3 is relatively stable always, inner wall tube 2 is not damaged；As p3 value is substantially increased, then breakage in inner wall tube 2；As
P3 value is fallen after rising, then inner wall tube 2 and the equal breakage of outer wall pipe 1.
