Embodiment
In order more clearly to understand above-mentioned purpose of the present utility model, feature and advantage, below in conjunction with the drawings and specific embodiments, the utility model is further described in detail.
A lot of details have been set forth so that fully understand the utility model during description below is concrete; but the utility model can also adopt other to be different from other modes described here and realize; therefore, protection domain of the present utility model is not subjected to the restriction of following public specific embodiment.
Need to prove, in the situation that do not conflict, the application's implementation column and the feature in embodiment can make up mutually.
As shown in Figure 1, the present embodiment valve air tightness detection system comprises main admission line 1, the first tensimeter 101, the first valve 102, the second valve 103, detection platform admission line 2, detection platform gas exhaust duct 3 and the second tensimeter 301; The first tensimeter 101, the first valve 102, the second valve 103 are set in sequence on main admission line 1 by air inlet direction (the diagram direction of arrow); Detection platform admission line 2 is arranged between the first valve 102 and the second valve 103, and is communicated with main admission line 1; The second tensimeter 301 is arranged on detection platform gas exhaust duct 3; Valve 6 to be detected is arranged between detection platform admission line 2 and detection platform gas exhaust duct 3.when detecting the impermeability of valve 6, close the first valve 102, open the second valve 103, guarantee that whole pipeline is in atmospheric pressure state, valve 6 is arranged between detection platform admission line 2 and detection platform gas exhaust duct 3, close the second valve 103, close valve 6 to be detected, open the first valve 102, the air intake opening of main admission line 1 enters pure air and boosts to set pressure, observe the first tensimeter 101, whether the second tensimeter 301 changes, if unchanged, open valve 6 to be detected, the air intake opening of main admission line 1 enters pure air and boosts to set pressure, observe the first tensimeter 101, whether the second tensimeter 301 changes, if unchangedly illustrate that valve 6 impermeability are good.
Further, go back installation of relief valve 302 on detection platform gas exhaust duct 3, in the time of detection, atmospheric valve 302 cuts out, and after one-time detection is completed, opens atmospheric valve 302, and pressure release is to zero, in order to detect next time.
Further, between the air intake opening of the first tensimeter 101 and main admission line 1, reduction valve 104 is set also, stable in order to guarantee to detect needed gaseous tension, can first by reduction valve 104, force value be set.
Further, also comprise the 3rd valve 105, the first pressure transducer 106, the second pressure transducer 303 and data processing and control system 4; The 3rd valve 105 is arranged on main admission line 1 between the first valve 102 and the second valve 103; The first pressure transducer 106 is arranged on main admission line 1 between the 3rd valve 105 and the second valve 103; The second pressure transducer 303 is arranged on detection platform gas exhaust duct 3; The second valve 103, the 3rd valve 105 are all electrical ball valves; The second valve 103, the 3rd valve 105, the first pressure transducer 106, the second pressure transducer 303 are electrically connected to data processing and control system 4 respectively.The first pressure transducer 106, the second pressure transducer 303 are used for responding to the gaseous tension in pipeline, and providing the pressure sensitive signal to data processing and control system 4, data processing and control system 4 controls the opening and closing of the second valve 103, the 3rd valve 105 by the pressure sensitive signal.For example, when the gaseous tension in pipeline is excessive, data processing and control system 1 controls the second valve 103 and closes and stop gas further to enter pipeline, also can control the 3rd valve 105 and open and rush down portion gas until close the 3rd valve 105 when in pipeline, gaseous tension is no longer excessive.
