Embodiment
In order to more clearly understand above-mentioned purpose of the present invention, feature and advantage, below in conjunction with the drawings and specific embodiments, the present invention is further described in detail.
A lot of detail has been set forth so that fully understand the present invention during description is below concrete; but the present invention can also adopt other to be different from other modes described here and realize; therefore, protection scope of the present invention is not by the restriction of following public specific embodiment.
It should be noted that, when not conflicting, the feature in the implementation column of the application and embodiment can combine mutually.
As shown in Figure 1, the present embodiment cryogenic globe valve durability test system, comprises low-temperature (low temperature) vessel 1, air inlet pipeline 2, gas exhaust piping 3, first valve 4, torque sensor 5, data processing and control system 6, first tensimeter 7 and the second tensimeter 8; Low-temperature (low temperature) vessel 1 provides test for low temperature environment for cryogenic globe valve 100 to be measured, such as the probe temperature provided is-196 DEG C; Air inlet pipeline 2 is used for cryogenic globe valve 100 to be measured air inlet; Gas exhaust piping 3 is used for the gas in cryogenic globe valve 100 to be measured to discharge; First valve 4 is manual ball valve, is arranged on air inlet pipeline 2; Torque sensor 5 is electrically connected with data processing and control system 6, is used for detecting moment of torsion when cryogenic globe valve 100 opens and closes; First tensimeter 7 is arranged between the first valve 4 and the air intake opening of air inlet pipeline 2, and the second tensimeter 8 is arranged on gas exhaust piping.During test, first cryogenic globe valve to be measured is communicated with gas exhaust piping with air inlet pipeline, close cryogenic globe valve to be measured, enter gas boost to set pressure from air inlet pipeline air intake opening, observe the first tensimeter, whether the second manometric pressure changes, if nothing, then open cryogenic globe valve to be measured, enter gas boost to set pressure from air inlet pipeline air intake opening, observe the first tensimeter, whether the second manometric pressure changes, if nothing, then illustrate that the impermeability of cryogenic globe valve to be measured is good; Next, cryogenic globe valve to be measured is immersed in low-temperature (low temperature) vessel, partially unrolling, close cryogenic globe valve to be measured, the moment of torsion that cryogenic globe valve to be measured is closed in torque sensor air exercise open and close simultaneously detects, and provide moment of torsion induced signal to data processing and control system, when the moment of torsion that torque sensor senses arrives greatly certain value, illustrate that cryogenic globe valve to be measured can not normally use, the durability that before statistics, cryogenic globe valve to be measured is opened, the number of times of closing can know cryogenic globe valve to be measured.
Further, low-temperature (low temperature) vessel 1 is for liquid nitrogen tank and be arranged on lifting table 9, and by the rising of lifting table 9, declining makes cryogenic globe valve 100 to be measured immerse, leave liquid nitrogen tank.
Further, torque sensor 5 connects servomotor 10, and servomotor 10 is electrically connected with data processing and control system 6, and servomotor 10 produces torque power.
Between first tensimeter 7 and the air intake opening of air inlet pipeline 1, reduction valve 11 is set.In order to ensure that the gaseous tension required for test is stablized, force value can be set by reduction valve 11.
