4results about How to "Affects durability" patented technology

This invention relates to the field of underground gas storage technology for compressed air energy storage power stations, specifically to a large-size sealed door structure for high-pressure underground gas storage. It includes a sealed door, a sealing ring fixing steel plate, a first sealing ring, and a second sealing ring. A maintenance passage is provided inside a reinforced concrete plug. The sealed door is connected to the reinforced concrete plug via a sealing door support hinge. The maintenance passage is connected to the gas storage through the sealed door. The sealing ring fixing steel plate is fixed between the sealed door and the reinforced concrete plug. Both the first and second sealing rings are interference-fitted between the sealing ring fixing steel plate and the sealed door, with the first sealing ring positioned outside the second sealing ring. The sealed door structure is simple, adaptable to complex operating conditions, and ensures durability and reliability. It employs conventional sealing methods to form two seals, creating a double-layered protective barrier, resulting in good sealing performance, simple maintenance, and low repair costs.

This invention relates to the field of bridge construction technology and discloses a positioning device for precast box girder expansion joint embedded reinforcement. The device includes two guide rails arranged parallel to each other. Each guide rail has a sliding seat at its top, and each sliding seat has a fixed telescopic column at its top. A rotating seat is rotatably mounted on the top of each telescopic column. A telescopic support beam connects the two rotating seats, and multiple support rods are connected to the bottom of the telescopic support beam. This invention enables precise movement and positioning of the expansion joint embedded reinforcement in four dimensions: longitudinal, angular, vertical, and transverse. It avoids the low installation accuracy of traditional embedded reinforcement processes, which necessitates welding and re-welding or repeated reinforcement correction, thus affecting bridge construction progress. It enables the positioning and installation of precast expansion joint embedded reinforcement in box girders with different skew angles, eliminating the need to weld and fix the precast expansion joint embedded reinforcement to the main reinforcement of the box girder top slab, thus avoiding quality defects such as weld burns and weld beads in the main reinforcement, which affect structural durability and load-bearing capacity.

The utility model relates to the technical field of glove machine, and disclose a double -deck hot -air circulation drying solidification's glove machine, including glove machine, the lower fixed joint of glove machine has the machine body, the left side of machine body is provided with the discharge gate, the top of discharge gate installs the drying -machine. This double -deck hot -air circulation drying solidification's glove machine, when the device works, the external gloves are knitted well in the inside glove machine, then the external gloves are sent out through the discharge gate of glove machine machine body, and are placed on the drying -rack, since the upper and lower sides of discharge gate are all installed hot -air blower A and hot -air blower B, can carry out up -down synchronous blast drying, and since the surface of drying -rack uses the grid and installs, can good ventilation, ensure that every side can evenly be dried and solidified by wind, play the role of up -down drying even solidification together, avoid the influence of the strength, durability, comfort and protective performance of glove caused by uneven heating.

The utility model provides a high-voltage connecting rod and ignition coil, high-voltage connecting rod includes rod body and install the waterproof ventilation piece on the rod body, the rod body is provided with first channel and second channel, the one end of first channel is used for being communicated with spark plug installation well, waterproof ventilation piece is located between second channel and first channel. The end, communicated with the first channel, of the second channel is a first end, the end, communicated with the outside of the ignition coil, of the second channel is a second end, and the second end is not higher than the first end in the axial direction of the high-voltage connecting rod. The first channel and the second channel are arranged in the high-pressure connecting rod, and the waterproof breathable piece is arranged between the first channel and the second channel, so that the high-pressure connecting rod not only has a splash-proof function, but also can quickly discharge accumulated water on the waterproof breathable film through the second channel under the extreme working conditions that a vehicle wades in water and an engine is submerged by water, and the service life of the high-pressure connecting rod is prolonged. Water is prevented from accumulating on the waterproof breathable film, so that the durability of the waterproof breathable film is not influenced.
