[. The detector allows you to use it! I = EThe accumulation of a specified amount of liquid in the body is detected, and the gas in the bladder L1:. This relates to an accumulator that can also detect a decrease in force. As shown in FIG. 1, a conventional bladder-type Aki-Mulator has a bladder 2 airtightly mounted inside a container main body 1, gas is filled into the bladder 2 by a filling means 3, and gas is supplied into the container main body 1. The valve 5 of the U tube 4 is opened to allow liquid to flow in and out against the gas pressure in the bladder 2, and the amount of liquid accumulated in the main body 1 of the container can be indirectly estimated from changes in the pressure of the liquid. ing. Therefore, since the temperature at the time of filling the gas and the temperature during operation are not constant, the sealing pressure decreases over a long period of time due to gas leakage. The amount of liquid introduced into the customer main body 1 is not constant because the polytropic index changes depending on the inflow speed of the liquid. For this reason, the pressure fluid used to operate the hydraulic machine is not only caused by small Jt and Ll force, but also causes troubles in the machine. Since it is not possible to measure the gas ratio sealed in the bladder unless all the liquid accumulated in the main body is released, the gas pressure of the tank must be checked in accordance with the provisions of Article 12, Item 25 of the General High Pressure Gas Maintenance Regulations. 7-J To do this, close the main valve of the pressure liquid cup string, open the drain valve to empty the main container, measure the air pressure inside the bladder, and after measuring, store the liquid again. I have to do it, but 24 hours +1
In the case of a 4I operating accumulator, such a measure would be impractical and impractical. For this reason, there is a problem in that the gas pressure is often not detected, resulting in an abnormal drop in the gas pressure, which often causes damage to the bladder. The present invention was made to solve this problem.
By providing a detector inside the bladder provided in the container main body that is activated by the bladder when liquid of specified b↓ is introduced into the container main body, the main body of the container can be detected. The gas enclosed in the bladder fJ
The first objective is to provide an accumulator that can measure -.Next, an example of implementing the accumulator according to the present invention will be explained based on the drawings.In Fig. 2, b is the main body of the container, It is made of a rigid material such as metal and has a shape with high pressure resistance. 7 is a bladder to be accommodated in the container main body 6, and is made of a flexible elastic material such as rubber, and one end of the bladder is fixed to the container main body 6. ,
The inside thereof is filled with gas by the filling means 8 solidified in the container main body 6. IJ [
It is a cylinder with a liquid inlet/outlet 9'' on the minus side, and a valve body 11 that is opened by a spring 10 on the inside and closed when pushed by the bladder 7 is supported by a shaft 12. A detector supported by a holder 14, which is activated when a certain amount of liquid is introduced into the container main body 6 and the bladder 7 contracts and approaches or contacts the detector 13, which will be described later. The valve is closed. 15 is the above-mentioned supply/discharge pipe 9.
A detector installed at the bottom of valve body 1 detects the discharge of accumulated liquid.
1 is lowered, it is actuated by an actuator 16 fixed to its shaft 12, and when magnetic actuation is used, the detector 15
The mounting part and the valve shaft 12 are made of non-magnetic material and are isolated from the steel supply/discharge tube 9 and the valve body 11. The liquid is sent to the container main body 6 and accumulated therein. 20 is motor 1
8 is a no-load starting valve, and 22 is a relief valve that is opened by the above-mentioned detector 15 and closed by the rotation detector 21 of the motor 18 to set the pressure of the circuit. Reference numeral 23 denotes a liquid storage valve, which is opened by the rotation detector 21 of the motor 18 described above and closed by the detector 13 described above. Reference numeral 24 denotes a liquid supply valve which is controlled so that it is opened when the hydraulic system for supplying the accumulated liquid requires liquid, and closed when it is no longer needed. The pressure accumulating circuit diagram shown in FIG.
When driven by the motor 18, the no-load starting valve 2o
Since is open, the motor and rotation detector 21 operate to close the no-load start valve 20, and open the liquid storage valve 2, so the pump 17 pumps the liquid from tank 9. The bladder 7 which is pre-pressurized with gas in the container main body I) is filled with liquid. The bladder 7 deforms as shown by the solid line in FIG. 2 and the detector 13 approach. Then, the detector 13 is activated, the liquid storage valve 23 is closed, and the no-load start valve 20 is activated.
is opened, the main body 6 is stopped, and liquid at a predetermined pressure is accumulated in the main body 6 of the container. When the accumulated liquid is required by the hydraulic system, the liquid delivery valve 24 is opened to drain the accumulated liquid. As a result, the bladder 7 expands, pressurizes the valve body 11 and releases its shaft 12.
The motor 18 is restarted to lower the 1/1 mover 16 and act on the detector 15, causing the bomb 7-17 to move downward.
When the container main body 6 is turned and the -\N&f=4 is sent, the bladder 7 contracts and approaches the detector 15, and when a specified amount of liquid has accumulated, the detector 15 is activated and the accumulated liquid is discharged. Stop I
t, so the amount of liquid stored in the accumulator is always kept constant. When this accumulator repeats storage and discharge as described above, the pressure and time of accumulation and discharge are measured and the standard values are recorded.
Compare J f with the standard f+&, and if f! If L is lowered, you will know that the L4 yuka sealed in the bladder 7 is lower, so if this state is reached, gas will be replenished into the bladder 7 and the standard accumulated pressure will be obtained. The bladder-type accumulator according to the present invention houses a detector in the bladder, and when a specified amount of liquid is introduced into the main body of the container, the detector is actuated by the contraction of the bladder to measure the amount of liquid. Since the supply is stopped, unlike conventional pressure-controlled systems, the accumulated liquid volume can be kept accurately constant, allowing for highly stable and reliable pressurized liquid storage.In addition, this accumulator with a constant accumulated liquid volume If you measure and record the standard values of pressure and time for accumulation and discharge, and compare the accumulated pressure at that time with the standard values at daily start-up, it is possible to maintain the filling gas in the bladder while keeping the liquid mainly in the container. It has the convenience of being able to detect a shortage of gas, and it completely prevents damage to the bladder due to a decrease in the amount of gas in the bladder, so it has a unique effect as an accumulator used for 24-hour continuous operation. An example of this is shown below. (1) An electrostatic capacitance wax cedar proximity switch is installed in the bladder charged in the main body of a container with a gas volume of 5.2 tons, and a liter is placed inside the bladder.
Kg/ai of gas is sealed and the liquid is sent to the main body of the container from the supply/discharge tube over 10 minutes, and the gas inside the bladder reaches 2K.
The position of the proximity switch was fixed such that it activated when pressurized to y/crlI. When the accumulated liquid was discharged from the main body of the container, the bladder expanded, and as a result, the actuator attached to the shaft of the valve body descended, activating the magnetic proximity switch and closing the valve body. At this time, the gas pressure inside the bladder is i, 2 to 7/cr
1, the discharge amount was 1051 t, and the discharge time was 9 minutes 10 seconds. (2) The bladder of the accumulator in example (1) is IK2
The pressure in the bladder is 22 to 9/cd, and in this case, the liquid pressure in the bladder is 1048 mm 1!1 Output time i, t is 7 seconds, and the gas pressure in the bladder in 1 /
It was crl.
