Description

Technical Field

[0001] The utility model relates to the field of oil storage devices, in particular to a telescopic flexible bag. Background Art

[0002] As we all know, the flexible bladder is a soft oil bladder, which is an oil storage container made of oil-resistant adhesive tape. It has the characteristics of small size, light weight, easy to fold and easy to carry, and has been widely used in daily life and industrial production. Because the flexible bladder is made of soft material, the shape of the bladder after storing liquid is generally an irregular shape, which will affect the storage capacity due to the size of the site. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a retractable flexible bag which fully utilizes space to increase storage capacity.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a retractable flexible bladder is provided with a flexible bladder body, characterized in that the flexible bladder body is an accordion structure, a pressure plate is fixed on the top of the flexible bladder body, an exhaust valve connected to the inner cavity of the flexible bladder body is installed on the pressure plate, and an oil inlet and outlet connected to the inner cavity of the flexible bladder body is installed at the bottom of the flexible bladder body. The flexible bladder body includes a fabric reinforcement layer, a polyurethane upper rubber layer and a polyurethane lower rubber layer, and the polyurethane upper rubber layer and the polyurethane lower rubber layer are arranged on the upper and lower surfaces of the fabric reinforcement layer.

[0005] The utility model has the advantages of simple structure, oil resistance, water resistance, aging resistance, strong environmental adaptability, etc.; it is not affected by the size of the site and fully utilizes the space to increase the storage capacity. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0007] Figure 1 It is a schematic diagram of the structure of the utility model;

[0008] Figure 2 It is a structural schematic diagram of the polyurethane coated cloth of the utility model.

[0009] In the figure, 1. exhaust valve, 2. flexible bladder, 3. oil inlet and outlet, 4. pressure plate, 211. fabric reinforcement layer, 212. polyurethane upper rubber layer, 213. polyurethane lower rubber layer. DETAILED DESCRIPTION

[0010] In the figure, the utility model shows a flexible capsule 2, which is an accordion-type structure. A pressure plate 4 is fixed on the top of the flexible capsule 2. The pressure plate 4 is made of aluminum alloy and connected to the top of the flexible capsule 2, and has the function of suppressing the oil sac liquid level and assisting in liquid discharge. An exhaust valve 1 connected to the inner cavity of the flexible capsule 2 is installed on the pressure plate 4. The exhaust valve 1 is made of aluminum alloy and is used to maintain pressure balance and prevent the oil-gas mixture from forming an air chamber at the top of the oil sac. An oil inlet and outlet 3 connected to the inner cavity of the flexible capsule 2 is installed at the bottom of the flexible capsule 2. The oil inlet and outlet 3 is a quick interface made of aluminum alloy and is used to control the inlet and outlet of the storage liquid by external valves and pipelines. The flexible capsule 2 is formed by high-frequency heat bonding of a fabric reinforcement layer 211, a polyurethane upper glue layer 212 and a polyurethane lower glue layer 213. The polyurethane upper glue layer 212 and the polyurethane lower glue layer 213 are arranged on the upper and lower surfaces of the fabric reinforcement layer 211.
