The feature of the utility model and other correlated characteristics are made further specifically by embodiment below in conjunction with attached drawing
It is bright, in order to the understanding of technical staff of the same trade:
Picture 1-4,1-10 is marked to be respectively as follows: piping lane 1, top plate 2, escape pipe 3, valve 4, bottom plate 5, water injection pipe 6, rubber in figure
Glue gasket 7, rubber strip 8, enclosure space 9, prestress hole 10.
Embodiment: as shown in Figs 1-4, the present embodiment, should more particularly to the watertight test system at a kind of piping lane straight cut
Pilot system include piping lane 1 and be arranged in piping lane 1 straight cut end face one circle rubber gasket 7 and one circle rubber strip 8, rubber
It is enclosed between glue gasket 7 and rubber strip 8 and constitutes an enclosure space 9, the enclosure space 9 is through water injection pipe 6 and external hydraulic pump
It is connected, hydraulic pump can be filled the water into enclosure space 9 to verify the waterproof seal of 1 splicing seams of piping lane.
As shown in Figs 1-4, watertight test system includes piping lane 1, and each piping lane 1, which successively flushes, to be linked together, in piping lane 1
It is embedded with a L shape escape pipe 3 on top plate 2, is additionally provided with a valve 4 thereon, a L shape note is embedded on the bottom plate 5 of piping lane 1
Water pipe 6；The straight cut end face periphery of piping lane 1 is provided with a circle preformed groove, a circle rubber gasket 7 is pasted in preformed groove,
Specifically neoprene adhesive is selected to be pasted in the present embodiment, having can room temperature cold curing, initial bonding strength be very big, intensity is built
It is vertical rapidly, adhesive strength it is higher, the advantages of high comprehensive performance, and rubber gasket 7 then specifically selects ethylene propylene diene rubber close
Packing, resistance to ozone, heat-resisting, ageing-resistant etc. are had excellent performance, and rubber gasket 7 may be designed as the structure of inner hollow, when its by
Splice when squeezing to two neighboring piping lane 1 with certain contractility, after the completion of flushing and has certain tension, guarantee waterproof
Sealing performance；Several prestress holes 10, two neighboring piping lane 1 are additionally provided in the region that the circle rubber gasket 7 is enclosed
Between by prestress hole 10 apply prestressing force；A circle rubber strip is additionally provided between rubber gasket 7 and prestress hole 10
8 namely rubber gasket 7 surround rubber strip 8, thus therebetween constitute one circle enclosure space 9, and water injection pipe 6 and go out
Tracheae 3 then connects with enclosure space 9 respectively just；The other end of water injection pipe 6 is also connected with a hydraulic pump, and hydraulic pump
Water inlet end is then connect with a water source, and hydraulic pump specifically selects the manual pump for having pressure gauge in the present embodiment, and manual pump has
