Abstract
The invention relates to a device for detecting leakproofness of plastic pipe joints, which comprises a cylindrical frame body, circular rubber air plugs, a gas-filled tube, a stopvalve and a pressure gauge, wherein the two circular rubber air plugs are coaxially nested on the two external walls at the ends of the cylindrical frame body and are provided with an air tap respectively; a circular cavity is arranged in the middle of the external wall of the cylindrical frame body; the air-filled tube which is communicated with the circular cavity on the external wall is arranged inside the cylindrical frame body; and the external end of the air-filled tube is provided with the pressure gauge and the stopvalve. The device has simple structure and scientific and reasonable design, can detect the leakproofness of the joints of the adjacent pipes which are well connected in the process of pipeline construction, detect the construction quality of the joints so as to ensure non-leakage of the pipeline joints, has the advantages of easy operation, fast detection, freedom from restriction by seasons, good universality and lower cost, can be widely applied to joint detection of plastic pipes and concrete pipes and has good promotion and application prospects.
Description
Technical field
The present invention relates to plastic conduit construction pick-up unit, particularly a kind of device for detecting leakproofness of plastic pipe joints.
Background technology
Development along with new technology, plastic pipe as the application in buried drain pipe road more and more widely, no matter be plastic pipe manufacturer, also be to use the user of pipeline all to wish pipeline zero seepage, making in the process of construction and making good use of plastic tube is of equal importance with producing the high-quality plastics pipe.For buried drain pipe road engineering is carried out quality control, must carry out the leakproofness check to the drainage pipeline after the construction.The existing method of inspection of China has two kinds: a kind of is traditional water method of inspection that closes, and another kind is the novel method of inspection of holding one's breath.
But existing pipeline closes the limitation that (water) gas method just progressively shows its check.Be embodied in: above-mentioned kind of method all is need be after piping erection finishes, between two well locations, detect, respectively pipe plug is installed in the pipe interior two ends, every termination upward pressure table and charging connector, by measuring hold one's breath in regulation tube drop value under (water) time of pipeline, check the whether compliant requirement of leakproofness of pipeline.Because have a plurality of pipe joints usually between two well locations, each interface shape then can't detect test, so just there is serious gas leakage hidden danger in its interface, must check the interface quality of connection with exclusive method, and workload is big, and the time is long.Because the connection of plastic tube is various, each connection all has different characteristics, and whether pipeline leaks, and interface is crucial.Therefore, control the quality of plastics pipe interface, just must adopt the stronger checkout equipment of versatility that the various interface form is tested.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of simple in structure, cost is low, easy and simple to handle, detect fast, be not subject to seasonal restrictions, device for detecting leakproofness of plastic pipe joints that versatility is stronger.
The present invention solves its technical matters and is achieved through the following technical solutions:
A kind of device for detecting leakproofness of plastic pipe joints is characterized in that:, gas-filled tube stifled by cylindrical frame body, ring-shaped rubber gas, stop valve and tensimeter constitute; Stifled at all coaxial ring-shaped rubber gas that is nested with of the two ends of cylindrical frame body outer wall, on this two ring-shaped rubbers gas is stifled valve is installed all; Cylindrical frame body outer wall medium position is shaped on annular cavity; At the inner gas-filled tube that the made annular cavity of a connection outer wall is installed of cylindrical frame body, this gas-filled tube outer end is equipped with tensimeter and stop valve.
Advantage of the present invention and beneficial effect are:
This device for detecting leakproofness of plastic pipe joints is simple in structure, design science is reasonable, in pipeline construction, can carry out leakproofness to the interface of the adjacent tubing that connected and detect, check the construction quality of interface, do not reveal to guarantee pipe joint, have easy and simple to handlely, detect fastly, be not subject to seasonal restrictions, versatility is good, lower-cost advantage, the interface that can be widely used in plastic tube, concrete pipe detects, and has good popularizing application prospect.
Description of drawings
Fig. 1 is structural representation of the present invention (cut-open view).
Fig. 2 is that the present invention is installed on the structural representation in the tubing interface.
Embodiment
The invention will be further described below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of device for detecting leakproofness of plastic pipe joints, it is stifled 1 by cylindrical frame body 2, ring-shaped rubber gas, gas-filled tube 3, stop valve 6 and tensimeter 5 constitute.Stifled at all coaxial ring-shaped rubber gas that is nested with of the two ends of cylindrical frame body outer wall, this ring-shaped rubber gas is stifled stifled for inflatable rubber gas, on two ring-shaped rubber gas are stifled valve 4 is installed all.Cylindrical frame body outer wall medium position is shaped on annular cavity 8.At the inner gas-filled tube that is communicated with the made annular cavity of outer wall of installing of cylindrical frame body, this gas-filled tube outer end is equipped with tensimeter and stop valve.
The mode of operation of this device for detecting leakproofness of plastic pipe joints is:
On construction ground the adjacent channel interface connect finish after, device for detecting leakproofness of plastic pipe joints is placed on the interface of adjacent tubing, as shown in Figure 2.
2. be full of gas with ring-shaped rubber gas is stifled, the inwall of the two and adjacent two tubing 7,9 is fitted tightly, guarantee air tight.
3. in the annular cavity of cylindrical frame body, supply gas by stop valve with external air pump, close stop valve after reaching certain pressure.
4. the pressurize certain hour is observed manometric pressure drop situation, to determine whether this interface has leakage.It is too fast that air pressure does not increase or air pressure descends, and there is gas leakage in the specification interface place, promptly needs pipeline junction is repaired.
The interface that this checkout equipment can be widely used in plastic tube, concrete pipe detects, and the quality control that connects of tubing, has easy to detectly, fast, and cost is low, and the time and labour saving such as is not subject to seasonal restrictions at advantage.
