Description

Technical Field

[0001] The invention relates to the technical field of supporting equipment for dry-type thin oil sealed gas cabinets, and in particular to an anti-floating oil device for dry-type thin oil sealed gas cabinets. Background Art

[0002] When the dry-type thin oil sealed gas tank is fed with gas, the gas tank piston rises under the pressure of the intake pipe. When supplying gas, the piston uses the gravity generated by its own weight to deliver gas to the user through the pipeline. The piston floats up and down between the gas tank measuring plates in the gas tank, and the sealing oil flows downward all the time to form an oil film to play a sealing role. The sealing oil flows into the oil tank at the bottom of the tank. As the oil level in the oil tank rises, the float relay starts the oil pump to send the sealing oil to the reserve oil tank on the top of the gas tank, and then flows into the piston oil tank along the inner side of the gas tank side plate through the overflow hole of the reserve oil tank. In this way, the sealing oil circulates back and forth between the piston oil tank and the oil tank at the bottom of the tank, allowing the gas tank piston to move up and down without leaking, which plays a sealing role and indirectly plays a lubricating role between the piston and the gas tank side plate.

[0003] However, when the sealing oil flows from the upper oil tank along the side plate of the gas tank to the piston oil tank, the piston cannot completely flow into the piston oil tank when the distance between the piston and the overflow port is more than 45 meters. Some oil droplets splash onto the piston, resulting in a reduction in the circulating oil volume of the sealing oil and pollution of the piston environment. In order to recover the splashed sealing oil, oil collecting plates are generally installed at the corresponding positions on the pistons at home and abroad, but the oil collecting effect is not ideal in actual operation. Summary of the invention

[0004] In view of the above problems, the object of the present invention is to provide a dry-type thin oil sealed gas tank oil splashing prevention device, which can effectively solve the problem of sealing oil splashing by blocking with a curtain.

[0005] The technical solution adopted by the present invention is as follows:

[0006] The present invention proposes a dry-type thin oil sealed gas tank oil drift prevention device, comprising a cloth curtain, a guide rope, a counterweight, a pulley and a suspension rope; the guide ropes are respectively arranged on both sides of the middle part of the top end of the gas tank piston, and the lower end of the guide rope is connected to the piston; the pulleys are respectively installed on both sides of the middle part of the lower end of the gas tank maintenance corridor through the suspension ropes and correspond to the guide rope positions; the upper ends of the guide ropes on both sides are connected to the counterweight after passing through the pulleys on both sides; the cloth curtain is correspondingly connected between the middle and lower areas of the guide ropes on both sides.

[0007] Furthermore, the length of the cloth curtain is half of the piston stroke of the gas tank, and the width of the cloth curtain is 200-300 mm larger than the width of the sealing oil overflow port.

[0008] Furthermore, the weight of the counterweight block is greater than half the weight of the guide rope plus the weight of the curtain.

[0009] Furthermore, the counterweight and the pulley are both made of Q235 ordinary carbon structural steel.

[0010] Furthermore, the guide rope and the suspension rope are both made of φ8 steel wire rope.

[0011] Furthermore, the curtain is made of PVC Oxford cloth.

[0017] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

They are only for the convenience of describing the present invention and simplifying the description, and do not mean that the device or element must have a specific orientation, be constructed and operated in a specific orientation.

[0019] See attached Figure 1-2 The specific structure of an embodiment of a dry oil seal gas tank anti-floating device proposed by the present invention is given. The anti-floating device 3 includes a cloth curtain 31, a guide rope 32, a counterweight block 33, a pulley 34 and a suspension rope 35.

[0020] In this embodiment, two guide ropes 32 are provided, and the two guide ropes 32 are respectively arranged between the top of the gas tank piston 13 and the two sides of the middle of the bottom end of the gas tank maintenance corridor 12, and the lower end of the guide rope 32 is connected to the top of the piston 13; two pulleys 34 are provided, and the two pulleys 34 are respectively installed on both sides of the middle of the lower end of the gas tank maintenance corridor 12 through a suspension rope 35 and correspond to the position of the guide rope 32; the upper ends of the guide ropes 32 on both sides are connected to the counterweight block 33 after passing around the pulleys 34 on both sides; the cloth curtain 31 is correspondingly connected between the middle and lower areas of the guide ropes 32 on both sides and the top of the piston 13.

[0021] The weight of the counterweight block 33 is greater than half the weight of the guide rope 32 + the weight of the curtain. The counterweight block 33 and the pulley 34 are both made of Q235 ordinary carbon structural steel. The guide rope 32 and the suspension rope 35 are both made of φ8 steel wire rope.

[0022] The length of the cloth curtain 31 is half of the stroke of the gas tank piston 13, and the width of the cloth curtain 31 is 200-300 mm larger than the width of the sealing oil overflow port 24. The cloth curtain 31 is made of PVC Oxford cloth.

[0023] The working principle of the present invention is:

[0024] When the gas tank 1 is fed with gas 15 through the inlet pipe 17, the piston 13 rises under the pressure of the gas 15. When the gas is supplied, the piston 13 uses the gravity generated by its own weight to deliver the gas 15 to the user through the pipe 17. The piston 13 floats up and down between the side plates 11 of the gas tank 1 in the gas tank 1, and the sealing oil 25 flows downward all the time to form an oil film to play a sealing role. The sealing oil 25 flows into the oil tank 16 at the bottom of the tank. As the oil level in the oil tank 16 rises, the float relay starts the oil pump station 21. The sealing oil 25 is sent to the reserve oil tank 23 at the top of the gas tank, and then flows into the piston oil tank 14 along the inner side of the side plate 11 through the overflow hole 24 of the reserve oil tank 23. In this way, the sealing oil 25 circulates back and forth between the piston oil tank 14 and the oil tank 16 at the bottom of the tank, so that the piston 13 can move up and down without leaking, which plays a sealing role and indirectly plays a lubricating role between the piston 13 and the side plate 11.

[0025] When the piston 13 is at the lowest position, the curtain 31 is fully unfolded; when the gas 15 enters the gas tank 1 and the piston 13 rises, the counterweight 33 gradually descends to the top of the piston 13 under the action of the counterweight 33; when the piston 13 continues to rise, the curtain 31 descends to the top of the piston 13 under the action of its own weight, and the piston 13 is at the highest position. When the piston 13 descends, the anti-slip oil device acts in the opposite way. The curtain 31 moves up and down with the piston 13, and the sealing oil splashing from the overflow port 24 can be effectively shielded.

[0026] Matters not covered in the present invention are all known technologies.

[0027] The embodiments described above are merely descriptions of preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
