Conventionally, a lid holding screw ring 12 in a pressure vessel is provided with a flange 17 on the outer periphery of the upper end of the screw ring 12 as shown in FIG. Since the ring 12 was to be locked, the screw ring 12 was attached to the flange 1.
7 plus machining allowance, and a machining drop must be provided between the screw and flange 17, so not only the material b in Figure 3 becomes shavings, but also Since the opening 2 in the pressure vessel becomes longer by the amount indicated by a in the same figure, the material cost and processing cost are high, which is uneconomical.
There was an inconvenience that the weight of the product was also heavy.

The present invention was devised to eliminate this drawback. An annular groove is provided at the upper part of the outer periphery of the screw ring, and a rigid split ring whose circular cross section partially protrudes is housed in the annular groove. It is an object of the present invention to provide a device capable of locking a screw ring without using a flange by bringing the part into contact with a slope provided on the inner edge of an opening in a pressure vessel.

In the figure, reference numeral 1 denotes a pressure vessel such as an accumulator, which is made of steel or the like to have a shape with high pressure resistance, and has an opening 2 in its upper part. Reference numeral 3 denotes a receiving step provided on the inner end side of the opening 2, which supports the lower surface of a flange 5 which also serves as a packing for the bladder 4. Reference numeral 6 denotes a lid fitted into the opening 2, and a holding step 7 of the flange 5 is provided around the outside of the lower part of the cover.
The flange 5 of the bladder 4 is sandwiched between the step part 3 and the step part 3, and an annular groove 8 is formed around the outer periphery, and a seal ring 9 is fitted into the annular groove 8.
A cylindrical portion 11 is provided in the center portion, into which an air supply valve 10 for sealing pressurized gas into the bladder 4 is inserted. 1
Reference numeral 2 denotes a retaining screw ring for the lid 6, which is formed on the inner periphery of the opening 2 and is screwed into an internal thread 13 to hold down the lid 6, and has an annular groove 14 formed on the upper outer periphery.
15 is a ring made of rigid material such as steel.
By using a split ring that is divided and fitted into the annular groove 14 and having a circular cross section with a part exposed from the annular groove 14, the presser screw ring 12 can be screwed into the opening 2 of the pressure vessel 1. , a portion protruding from the annular groove 14 comes into contact with a slope 16 provided on the inner periphery of the opening 2 to prevent the presser screw ring 12 from being screwed in;
The presser screw ring 12 is securely locked onto the opening 2. Reference numeral 17 denotes a flange provided on the upper part of the conventional presser screw ring 12, which is engaged with the upper end of the opening 2.

When the device configured as described above is used in an accumulator in which the inside of the pressure vessel 1 is divided into a gas chamber and a liquid chamber by the bladder 4, the bladder 4 is inserted into the pressure vessel 1 from the opening 2, and the flange 5 is supported by the step part 3, the lid body 6 is fitted into the opening 2, and the flange 5 of the bladder 4 is placed between the holding step part 7 and the step part 3, When the presser screw ring 12 with a rigid split ring 15 fitted into the annular groove 14 on the upper outer periphery is screwed into the internal thread 13 provided on the inner periphery of the opening 2, the screw ring 12 descends inside the opening 2 and closes the lid. The flange 5 of the bladder 4 is clamped between the holding step 7 of the lid 6 and the receiving step 3 of the pressure vessel 1 to firmly and reliably attach the bladder 4 to the pressure vessel 1. 5 to exhibit a complete sealing function. At this time, the split ring 15, which partially protrudes from the annular groove 14, has its outer lower surface connected to the slope 16 provided on the inner periphery of the upper end of the opening 2.
The presser screw ring 12 locks onto the opening 2 of the pressure vessel 1 in order to prevent the screw ring 12 from being screwed into the pressure vessel 1.

The device configured as described above accommodates a rigid split ring in the annular groove of the presser screw ring, with a part protruding from the groove, and the protrusion is connected to the inner edge of the opening in the pressure vessel provided with sealing means by the flange of the bladder. Since the presser screw is locked in the opening by coming into contact with the slope provided in the opening, the conventional flange is unnecessary and the length of the opening can be made shorter, which saves the material in the parts a and b in Figure 3. At the same time, it is economical because processing of these parts can be omitted, and it also has the unique effect of reducing the weight of the pressure vessel.
