Description

Изобретение относитс  к известным в технике приборам дл  определени  среднего индикаторного давлени  в цилиндрах поршневвтх машин при помощи манометра, соединенного с областью измер емого давлени  через промежуточные баллоны, снабженные трубками и кранами дл  дросселировани  рабочего агента (газа, пара).The invention relates to devices known in the art for determining the average indicated pressure in cylinders of piston machines with a manometer connected to the region of measured pressure through intermediate cylinders equipped with tubes and taps for throttling the working agent (gas, steam).

Отличие предлагаемого прибора заключаетс  в том, что прибор позвол ет определ ть помимо среднего и максимальное давление конца сжати  или конца горени  в ци .линдрах поршневых машин. Прибор выполнен в виде двух камер, соединенных между собой. Кажда  камера снабжена отдельным манометром . Одна из камер предназначена дл  замера среднего, а друга  - максимального давлени .The distinction of the proposed instrument is that the instrument allows determining, in addition to the average, the maximum pressure of the end of compression or the end of combustion in the cylinders of piston machines. The device is made in the form of two cameras connected to each other. Each chamber is equipped with a separate pressure gauge. One of the chambers is designed to measure the average and the other is the maximum pressure.

Прибор состоит из снабженной игольчатым клапаном 3 дроссельной камеры / с манометром 2. .Этим прибором определ ютс  средние давлени . При помощи тройника 7с перекрывным краном и трубки 5 к камере / присоединен коллектор 4, предназначенный дл  замера максимального давлени . Коллектор 4 имеет р д отверстий 9, ж которым подвод тс  от .испытательных цилиндров или рессиверов трубки 10 с перекрывными кранами . На коллекторе 4 устанавливаетс  манометр 6, снабженный шариковым клапаном 5, выполн ющим роль невозвратного клапана.The device consists of a throttle chamber / pressure gauge 2 equipped with a needle valve 3. The average pressures are determined with this device. Using a tee 7c with a shut-off valve and a tube 5 to the chamber / a manifold 4 is attached, intended for measuring the maximum pressure. The collector 4 has a series of holes 9, which are supplied from test cylinders or receivers of the tube 10 with shut-off valves. A manifold 6 is mounted on the manifold 4, equipped with a ball valve 5, which acts as a non-return valve.

К коллектору 4 при помощи тройника 11с перекрывным краном может подсоедин тьс  воздущна  труба от баллона сжатого воздуха, служаща  дл  зар дки прибора воздухом нужного давлени .An air pipe from a compressed air cylinder can be connected to the collector 4 with the help of a tee 11c by means of a shut-off valve, which serves to charge the device with air of the required pressure.

Манометр 2 показывает истинное среднее давление в данном цилиндре или в группе цилиндров. На манометре 6 коллектора 4 показани  могут быть истинными или относи .тельными максимальными давлени ми в данном цилиндре в зависимости от соотношени  диаметра трубки 10 к внутреннему диаметру коллектора 4.Pressure gauge 2 shows the true average pressure in a given cylinder or in a group of cylinders. On manifold gauge 6, the readings may be true or relative maximum pressures in the cylinder, depending on the ratio of the diameter of the tube 10 to the inner diameter of the collector 4.

Включение прибора в действие осуществл етс  путем открывани  кранов, соедин ющих прибор с данным цилиндром или с группой цилиндров . Прибор устанавливаетс  в любом месте, но длина и-диаметры всех трубок 10, идущих от цилиндров , дл  более точных показаний прибора принимаютс  одинаковыми .The device is put into operation by opening the valves connecting the device with this cylinder or with a group of cylinders. The device is installed at any place, but the length and diameters of all the tubes 10 coming from the cylinders are taken to be the same for more accurate instrument readings.
