- This sealing material is formed of chloroprene rubber, acrylonitrile butadiene rubber, or the like (see, for example, Patent Documents 1 and 2).
- the sealing material interposed between the tank and the buffer member has one end fixed to the inner peripheral surface of the tank and the other end fixed to the outer edge of the buffer member. Therefore, the vicinity of one end (tank side end) and the other end (buffer member side end) of the sealing material is always in a bent state, and the bent state changes as the movable lid and the buffer member move up and down. To do. Therefore, the sealing material is required to have bending resistance in addition to excellent airtightness that prevents leakage of stored gas.
- the sealing material when the gas holder is disposed in a cold region, the sealing material may be cooled to near the embrittlement temperature of the rubber.
- the tank-side end portion of the sealing material is easy to transmit the low temperature of the outside air through the tank wall surface.
- the sealing material is formed of chloroprene rubber or acrylonitrile butadiene rubber, it has poor cold resistance, and therefore there is a problem that cracks are likely to occur at low temperatures in cold regions even if cracks do not occur at the bent portions at room temperature.
- the sealing material is made of rubber other than chloroprene rubber or acrylonitrile butadiene rubber, the durability (gas resistance) against methane gas or the like is inferior, so that there is a problem that the essential function as the sealing material is hindered.
- An object of the present invention is to provide a gas holder seal material and a gas holder seal structure capable of maintaining excellent airtightness while improving the bending resistance of a cold region under a low temperature.
- the gas holder sealing material of the present invention includes an inner peripheral surface of a tank constituting the gas holder, and a movable lid that moves up and down in the tank.
- a gas holder sealing material formed in a cylindrical shape interposed between an outer edge of a buffer member that moves up and down, a tank side end that is a side fixed to the inner peripheral surface of the tank, and an outer edge of the buffer member
- At least the tank side end of the buffer member side end to be fixed to the part, both surfaces of the end are covered with ethylene propylene diene rubber, and the tank side end and the buffer member side end
- the other parts are characterized in that ethylene propylene diene rubber is uncoated.
- the seal structure of the gas holder of the present invention includes an inner peripheral surface of a tank constituting the gas holder and an outer edge of a buffer member that moves up and down in the tank on the outer peripheral side of the movable lid in conjunction with the movable lid that moves up and down in the tank.
- the tank side end of the gas holder sealing material is fixed by protruding from the inner peripheral surface of the tank A tank-side fixing member; and a buffer-member-side fixing member that is provided on an outer edge of the buffer member and fixes the buffer-member-side end of the gas holder seal material, the tank-side end and the buffer-member-side end At least the tank side end of the part is covered with ethylene propylene diene rubber on both sides of the end, and with respect to parts other than the tank side end and the buffer member side end

- a tank-side fixing member that fixes the sealing material across the tank-side end portion, and a buffer-member-side fixing member that is provided on an outer edge portion of the buffer member and fixes the buffer member-side end portion of the gas holder sealing material.
- the surface of the tank side end facing the inner peripheral surface of the tank is covered with ethylene propylene diene rubber, and the surface of the tank side fixing member facing the tank side end is ethylene propylene. Characterized in that it is covered by Njiengomu.
- the gas holder seal material of the present invention (hereinafter referred to as a seal material) has at least both of the tank side end portion and the buffer member side end portion with respect to at least the tank side end portion.
- the tank side end that is covered with diene rubber (hereinafter referred to as EPDM) and that is not covered with EPDM for the parts other than the tank side end part and the buffer member side end part, so that the low temperature of the outside air is most easily transmitted
- EPDM having excellent cold resistance comes into contact with the inner peripheral surface of the tank. This improves the bending resistance of the tank side end portion at a low temperature.
- the EPDM intervenes, it becomes difficult for the low temperature of the outside air to be conducted to other portions, so that the bending resistance at a low temperature as the whole sealing material is improved. Accordingly, even when the gas holder is disposed in a cold region, it is possible to prevent a problem that a crack is generated in the sealing material at a low temperature. Further, since only the end portion of the sealing material is covered with EPDM, any material having excellent durability (gas resistance) against the gas stored in the tank can be selected for the main body portion of the sealing material. Therefore, it can be satisfactorily maintained without impairing the essential function (air tightness) as the sealing material.
- the coating length of EPDM can be made different between one side of the end covered with EPDM and the other side. As a result, it is possible to avoid a sudden change in the bending rigidity at the boundary between the part covered with EPDM on both sides and the part not covered with EPDM. This eliminates excessive stress concentration and is advantageous for improving the bending resistance. Moreover, since EPDM is used only for a necessary part (length), the amount of EPDM used can be minimized and material cost can be suppressed.
- the coating thickness of EPDM can be made different between one surface at the end covered with EPDM and the other surface. As a result, the coating thickness of the EPDM can be reduced to the minimum necessary on each surface, and an increase in the bending rigidity of the end portion coated with the EPDM can be suppressed. This is advantageous for improving the bending resistance. In addition, material costs can be reduced by minimizing the amount of EPDM used.
- the coating thickness of EPDM is set to 1.2 mm to 1.4 mm, for example. Thereby, bending resistance can be improved, suppressing effectively that the low temperature of external air is transmitted to the main-body part of a sealing material.
- the gas holder seal structure of the present invention includes the tank side fixing member and the buffer member side fixing member, and at least the tank side end portion and the buffer member side end portion with respect to the tank side end portion, Both surfaces of the end portion are covered with EPDM, and the portions other than the tank side end portion and the buffer member side end portion are configured so that EPDM is not covered, and the surface of the portion not covered with EPDM of the sealing material is Regardless of the vertical position of the buffer member, it does not come into contact with the inner peripheral surface of the tank and the tank side fixing member, so that the low temperature of outside air is not easily conducted to the portion of the seal material that is not covered with EPDM, and the low temperature of the entire seal material Bending resistance can be improved.
- EPDM comes into contact with the inner peripheral surface of the tank, it is possible to improve the bending resistance of the tank side end portion at a low temperature. Therefore, even when the gas holder is disposed in a cold region, it is possible to prevent a problem that a crack occurs in the sealing material at a low temperature.
- both surfaces of the buffer member side end are covered with EPDM, and the surface of the portion not covered with EPDM of the sealing material does not contact the buffer member regardless of the vertical position of the buffer member.
- This improves the resistance to bending at low temperatures at the end of the buffer member that is easy to transmit the low temperature of the outside air, such as the end on the tank side, and further improves the resistance to bending as a whole of the sealing material at low temperatures. . Therefore, it becomes more advantageous to prevent the occurrence of cracks at low temperatures.
- another gas holder sealing structure of the present invention includes a tank side fixing member and a buffer member side fixing member, and a surface of the tank side end facing the inner peripheral surface of the tank is covered with EPDM. Since the surface facing the tank side end of the tank side fixing member is covered with EPDM, the low temperature of the outside air is hardly conducted to the part of the sealing material that is not covered with EPDM. The bending resistance can be improved. Further, since the sealing material itself does not come into contact with the inner peripheral surface of the tank and the tank side fixing member at the tank side end portion, it is possible to improve the bending resistance of the tank side end portion at a low temperature.
