Abstract
The utility model discloses a finished prestressed concrete cylinder pipe (PCCP) pressure testing machine which comprises a steel inner container and a sealing top cover, wherein the sealing top cover is provided with at least two socket sealing rings, at least two steel lantern rings that are mutually nested and sealed are arranged on a base of the steel inner container, and a stressed pull rod is arranged between the base of the steel inner container and the sealing top cover. The finished PCCP pressure testing machine has the advantages that as the PCCP bell mouth sealing steel lantern rings of various specifications and the sealing top cover with the socket sealing rings of various specifications are adopted, and the top cover is connected with the inner container through bolts, the internal pressure sealing effect of PCCP of various specifications in internal hydraulic test is realized.
Description
Technical field
The utility model relates to a kind of PCCP production tube pressure testing machine.
Background technology
At present, the PCCP production tube need carry out internal pressure test, because PCCP is many according to the internal diameter specification, every kind of specification PCCP needs corresponding specification production tube pressure testing machine, production cost height.
The utility model content
The utility model has overcome shortcoming of the prior art, and a kind of PCCP production tube pressure testing machine is provided, and can bear plurality of specifications PCCP internal pressure test.
The technical solution of the utility model is: a kind of PCCP production tube pressure testing machine, comprise steel inner container and top pressure closure, and described top pressure closure is provided with at least two spigot seal rings.
At least two steel collars, the mutually nested and mutual sealing of each steel collar are set on the base of steel inner container; Between the base of steel inner container and top pressure closure, be provided with stressed pull bar.
Compared with prior art, the utility model has the advantages that: owing to adopt many specifications PCCP bellmouth sealing steel collar and with the top pressure closure of many specifications spigot seal ring, and top cover is connected with inner bag by bolt, realizes the inner pressuring sealing effect of many specifications PCCP when the interior hydraulic testing.
Description of drawings
The utility model will illustrate that wherein: Fig. 1 is a structural representation of the present utility model by example and with reference to the mode of accompanying drawing; Fig. 2 is the structure enlarged diagram of A part among Fig. 1; Fig. 3 is the structure enlarged diagram of B part among Fig. 1.
Embodiment
A kind of PCCP production tube pressure testing machine as shown in Figure 1, comprises steel inner container 1, the steel collar 2, top pressure closure 3, stressed pull bar 4.As shown in Figures 2 and 3, at least two steel collars 2 are set on the base of steel inner container 1, each steel collar 2 is mutually nested and can seal mutually, to realize the sealing to the PCCP bellmouth of all size; At the top of steel inner container 1 top pressure closure 3 is set, top pressure closure 3 is connected with steel inner container 1 by bolt, and top pressure closure 3 is provided with at least two spigot seal rings 5, to realize the sealing to the PCCP socket of all size.By such structure setting, in carrying out PCCP, during the hydraulic testing, between PCCP body, steel inner container 1, the steel collar 2 and band top pressure closure 3, just can form airtight hydraulic pressure space.
In order to increase the bearing capacity of pressure testing machine, stressed pull bar 4 also can be set, the two ends of stressed pull bar 4 are connected with top pressure closure 3 with the base of steel inner container 1 respectively.
