Description
Technical field
The utility model relates to a kind of hydro-test fast replacing device with overvoltage protection effect.
Background technology
At present, in the production of high speed marine diesel, casing, shell part all will carry out intensity and the sealing that parts body is checked in hydro-test conventionally, to meet request for utilization.Existing hydro-test adopts pressing machine water pipe to be attached directly to test fixture more, middle mounting ball valve and manometric mode are carried out, concrete structure as shown in Figure 1, comprise: pressing machine 101, X-over 102, flexible pipe 103, ball valve 104, three connect piece 105, tensimeter 106 and test fixture 107, wherein, during existing hydro-test, often adopt the mode that is attached directly to fixture interface from pressing machine to carry out the UNICOM of pipeline, middle connecting joint mostly is nonstandard design, dimensions is not of uniform size, manufactures difficulty.In existing scheme, lack over-pressure safety device, pressure is difficult to accurately control in uphill process, often occurs that pressure surpasses the situation of technical papers requirement, causes the phenomenon that seal element can not effective sealing to occur.
Meanwhile, existing scheme adopts a tensimeter to carry out observed pressure indicating value, and occasional occurs that tensimeter is malfunctioning, causes pressure excessive, causes attachment bolt distortion, fracture, causes security incident.
Utility model content
Goal of the invention of the present utility model is to provide a kind of hydro-test fast replacing device with overvoltage protection effect; in order to overcome prior art, adopt a tensimeter to carry out observed pressure indicating value; occasional occurs that tensimeter is malfunctioning; cause pressure excessive; cause attachment bolt distortion, fracture, cause the shortcoming of security incident.
It is as follows that the utility model solves the problems of the technologies described above taked technical scheme:
A kind of hydro-test fast replacing device with overvoltage protection effect, between pressing machine (1) and test fixture (13), be disposed with the first X-over (2) being connected together, flexible pipe (3), male joint (4), female joint (5), ball valve (6), crossover sub (7), T-valve piece (9), four-way valve piece (10), between described T-valve piece (9) and four-way valve piece (10), by conduit, be connected, wherein, one end of T-valve piece (9) connects a safety valve (8), two ends are connected with conduit with crossover sub in addition, the two ends of four-way valve piece (10) are connected with again tensimeter (11) separately, two ends connect respectively described conduit and test fixture (13) in addition.
Further, preferably, the specification of described tensimeter (11) is identical.
After the utility model has been taked such scheme, due to two tensimeters being installed, examine mutually, improve the use accuracy of whole system.And the newly-increased safety valve of this device, makes whole system have releasing pressure automatically function, can effectively avoid the generation of security incident, for operating personnel provide safe and reliable guarantee.
Other features and advantages of the utility model will be set forth in the following description, and, partly from instructions, become apparent, or understand by implementing the utility model.The purpose of this utility model and other advantages can be realized and be obtained by specifically noted structure in the instructions write, claims and accompanying drawing.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in detail, so that above-mentioned advantage of the present utility model is clearer and more definite.
Fig. 1 is the structural representation of prior art;
Fig. 2 is the structural representation that the present invention has the hydro-test fast replacing device of overvoltage protection effect.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in detail.
The object of the invention is to overcome the deficiency in existing scheme, realize quick, positive connection in hydraulic pressure process, is that existing scheme increases over-pressure safety device, protection operating personnel's personal safety.
Specifically, the Basic Design thinking of whole system is:
1. between whole system and part and pressing machine, can install fast and effectively;
2. the non-standard that parts should adopt standard component or be convenient to manufacture;
3. two tensimeters need be at least set with the accuracy of mutual inspection pressure;
4. needing increases over-pressure safety device, avoids occurring security incident.
Shown in concrete system composition diagram 2, a kind of hydro-test fast replacing device with overvoltage protection effect, between pressing machine 1 and test fixture 13, be disposed with the first X-over 2 being connected together, flexible pipe 3, male joint 4, female joint 5, ball valve 6, crossover sub 7, T-valve piece 9, four-way valve piece 10, between described T-valve piece 9 and four-way valve piece 10, by conduit, be connected, wherein, one end of T-valve piece 9 connects a safety valve 8, two ends are connected with conduit with crossover sub in addition, the two ends of four-way valve piece 10 are connected with again tensimeter 11 separately, two ends connect respectively described conduit and test fixture 13 in addition.
Further, preferably, the specification of described tensimeter 11 is identical.
Key point of the present invention is as follows:
1. the mode that adopts two tensimeters mutually to check is guaranteed the accuracy of test pressure;
2. adopt the mode of mounting safety valve to avoid pressure moment increase to cause operating personnel's hazard to person accident to occur.
Effect of the present invention is as follows:
1. simple in structure, easy to use.Operating personnel only need be connected with mounted test fixture this fast replacing device with part, operate very easy;
Cost of manufacture low, be convenient to promote the use of.The most of parts of this fast replacing device are all standard component, can directly purchase on the market, and only indivedual parts are non-standard, need customize, and cost of manufacture is low, be convenient to promote the use of;
3. two tensimeters are installed and are examined mutually, improve the use accuracy of whole system.
4. newly-increased safety valve, makes whole system have releasing pressure automatically function, can effectively avoid the generation of security incident, for operating personnel provide safe and reliable guarantee.
Finally it should be noted that: the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
