Description
Изобретение относитс к измерительно технике, в частности к определению объем негерметичных емкостей. По основному авт. св. № 398829 известен способ определени расчетным пут объема емкостей по данным, полученным путем измерени изменени давлени выте кающего из них газа по времени, и измерени расхода газа в зависимости от давлени . 1. Однако дл случаев, когда истечение существенно отличаетс от изотермического , измеренные этим способом величины объемов емкостей несколько отличаютс от истинных величин. Цель изобретени - повышение точност измерени . Это достигаетс тем, что по предлагаемому способу дополнительно измер ют изменение температуры газа во времени в процессе истечени его через неплотности и по полученным данным расчетным путем определ ют искомый объем. На чертеже показан график температуры Т во внутренней полости в зависимости от времени истечени газа через неплотности , С учетом изменени температуры формула вычислени внутреннего объема емкости:-г RT -t Gc-tldt V д Р - uPj, принимает вид R 1 TiТ, I TiT-biGCOd-t. де I uUldt - sec газа, прошедti шего через неплотности за промежуток времени от i, по t, , определенный с учетом изменени температуры в процессе истечеи ; Т, - температура газа внутри объема мкости при t ;The invention relates to a measuring technique, in particular to the determination of the volume of untight containers. According to the main author. St. No. 398829, a method is known for determining the calculated volume of the volume of the containers according to the data obtained by measuring the change in pressure of the gas flowing out of them over time, and measuring the flow of gas as a function of pressure. 1. However, for cases where the outflow is significantly different from isothermal, the volumes of the volumes of the containers measured in this way differ slightly from the true values. The purpose of the invention is to improve the measurement accuracy. This is achieved by the fact that according to the proposed method, the change in gas temperature in time during its outflow through leakages is additionally measured and the required volume is determined from the obtained data by calculation. The drawing shows a graph of the temperature T in the internal cavity as a function of the gas outflow time through leakages. Considering the temperature change, the formula for calculating the internal volume of the tank is: -r RT -t Gc-tldt V d P - uPj, takes the form R 1 TiT, I TiT -biGCOd-t. de I uUldt - sec of gas passing through leakages over a period of time from i, with respect to t, determined taking into account the temperature change during the expiration; T, is the gas temperature inside the vessel volume at t;
Т.- температура газа внутри объема емкости при ±2. T.- gas temperature inside the volume of the vessel at ± 2.

Предложенный способ осуществл ют следующим образом.The proposed method is carried out as follows.
измер ют изменение давлени вытекающего газа, расход газа и рассматривают процесс изменени температуры во времени при изменении избыточного давлени (разрежени ). По полученным данным из указанной зависимости определ ют внутренний объем емкостей .measure the pressure change of the outgoing gas, the gas flow rate and consider the process of temperature change over time with a change in overpressure (vacuum). According to the obtained data, the internal volume of the containers is determined from this dependence.
