(54) ЖИДКОСТЕМЕР(54) LIQUID TESTER

Изобретение относитс к области 13зьз@ рени объема жидкости и может быть использовано в различных отрасл х народного хоз йства дл учета жидких сред.The invention relates to the field of liquid volume and can be used in various sectors of the national economy to account for liquid media.

Известны жидкостемеры, содержащие ме рительную камеру, разделенную на две рабочие полости гибкой диафрагмой, золотниковые механизмы переключени потока, установленные в каждой рабочей полости а соединенные между собой штоком, а также с диафрагмой через механическую св зь с упо рами 1.Fluid gauges are known that contain a measuring chamber divided into two working cavities by a flexible diaphragm, spool flow switching mechanisms installed in each working cavity and interconnected by a rod, as well as with the diaphragm through a mechanical connection with stops 1.

Однако такие жидкостемеры громоздки и ими невозможно регулировать расход протекающей через них жидкости.However, such liquid gauges are cumbersome and it is impossible for them to control the flow rate of the fluid flowing through them.

Известны также жидкосгемеры, содержа щие устройство дл регулировани расхода протекающей через них жидкости 2,Fluid diets are also known to contain a device for controlling the flow of liquid 2 flowing through them.

Однако в этих жидкостемерах устройство дл регулировани расхода, сложно KOHCTPJTCтивно .However, in these gauges, the device for controlling the flow rate is difficult to KOHCTPJTC.

Дл обеспечени компактности конструкции в предлагаемом устройстве шток пропущен через центр мембраны,To ensure a compact design in the proposed device, the rod is passed through the center of the membrane,

Кроме того, дл обеспечени регулировани расхода жндксх;ти в предложенном устройстве шток снабжен рычагом поворота вокругIn addition, in order to ensure the regulation of the flow rate of the HDD; in the proposed device, the rod is equipped with a lever for turning around

СБОаЙ ОСЕ.FAST ECHO.

На чертеже показан описываемый жидкостемер , где 1- лева , а 2-права части корпуса образующие мерительную камеру 3; 4-гибка Диафрагма, через центр которой прощг-щен што 5, соединенный при помощи штифтов с залотн ками 6 и 7, помещенными в гильзах 8 st 9.The drawing shows the described fluid meter, where 1 is the left and 2 are the right parts of the body forming the measuring chamber 3; 4-bend The diaphragm, through the center of which is pinched 5, connected by means of pins to the grommets 6 and 7, placed in sleeves 8 st 9.

Огверсти 1О и 11 в гильзах соедин ют ЗШ1ОТКШС 6 с подвод щим трубопрсжодом, а 12 13 - с отвод щим трубопрсводом. Огверстй 14 и 15 в золотниках 6 и 7 сообщены с рабочими ПОЛОСТЯМИ камеры 3. Отварстн Ю., 11, 14 и 15 выполнены в виде узких секторных щелей.The caps 1O and 11 in the sleeves are connected to the ЗШ1ОТКШС 6 with the inlet pipe, and 12 13 - with the outlet pipe. Ogersti 14 and 15 in the spools 6 and 7 are communicated with the working CAVITY of chamber 3. Yu. 11, 14, and 15 are made in the form of narrow sector slits.

Claims

A spring-loaded stop 16s is mounted on the rod 5, which rests against the wall of the TS spool and spring-loaded stop 17, which rests through the pin on the cracker 18, is mounted in the longitudinal slot of the rod 5 and is moved using an adjustment die 19. The mechanism 20 of rotation of the spools around its axis is mounted on the right end rod 5. The finger 21, pressed by the spring 22, ensures the fixation of the rod 5 in the extreme positions. The screw 23 adjusts the degree of compression of the spring 22. The latch pin is placed in one of the channels of the agulka 24 attached to the stem 5. The ferromagnetic sensor of the rod stroke counter 5 contains the flag 25 and the coil 26. The fluid-meter works as follows The fluid enters through the combined hole Yu in galts 8 The hole in the spool 6 into the left working cavity: the suction chamber 3. At the same time, the fluid in the right working cavity is forced out through the combined holes 15 and 13 in the gold 7 and gland 9. At the same time, the flexible 4 moves left It rests against the spring-loaded stop 16, compresses its spring, closes the bushings of the stop 16, and pushes the rod 5 with the spools 6 and 7 to the right. In this case, the latch pin 21, squeezing the spring 2.2, exits the right groove of the sleeve 24. The compressed spring-loaded stop 16 expands and moves the bolt 5 s installed. "And with the spools 6 and 7 on it in the rightmost posture. Then the finger 21 under the action of the spring 22 is installed in the left groove of the sleeve QC 24, the JCK 6 and 7 are fixed in this flightkey and the holes 11 and 12 in the sleeves 8 and 9 are aligned with the holes of the spools 14 and 15 of the spool 6 and 7, and the cycle is repeated is. W-5. When completing an optically sequential double-stroke, moves the flag 25 and the slots of the coil 26 of the ferromagnetic sensor, the electrical impulses of which are counted by the counter. Using the adjusting screw 19, set the moment of operation of the switching mechanism of spools 6 and 7, affecting the movable cracker 18, thereby achieving regulation of the working volume of chamber 3. Turning the handle of the turning mechanism 2 O changes the combined area of the flow area formed by the openings of spools 6 , 7 and sleeves 8, 9, and thereby change the flow rate. Claim 1, A fluid meter containing a measuring chamber divided into two working cavities by a flexible diaphragm, spool flow switching mechanisms installed in each working cavity and connected by a rod to each other, as well as to the diaphragm, characterized in that in order to ensure the compactness of the design, the pcb is passed through the center of the flexible diaphragm. 2, the Liquid Steam Tester according to claim 1, in connection with the fact that, in order to control the flow of fluid, the rod is provided with a pivoting lever around its axis.
