This invention relates to the field of intelligent transformer technology, specifically to an intelligent transformer with protective functions, including a transformer main body, a pressure relief mounting component installed on the transformer main body, and a pressure relief device installed on the pressure relief mounting component; the pressure relief mounting component is used to detect the oil level; the pressure relief device is used to release air pressure; a moisture-absorbing component is installed on the pressure relief mounting component; a fin detection component is installed on the transformer main body; the fin detection component is used to monitor fin deformation; the pressure relief device can be used to release pressure in a timely manner when the insulating oil and air pressure inside the transformer main body rises, which can ensure the safe operation of the transformer main body. At the same time, this structure uses a float to monitor the insulating oil level, and in conjunction with a control switch, it can automatically control the oil discharge through the discharge solenoid valve, and the oil discharged by the discharge solenoid valve contains a large amount of sediment impurities.

This utility model discloses a sealing socket with a novel bent structure, including a plug assembly and an elbow assembly. The elbow assembly includes an integral elbow and an elbow nut. One end of the integral elbow is mounted on one side of the plug assembly and connected by the elbow nut. This utility model provides a first bend that bends outward at the end of the integral elbow. A stepped surface is provided on the corresponding end of the plug assembly, forming a second bend that mates with the first bend. The end of the first bend abuts against the stepped surface, forming a sealing groove with the second bend. A sealing ring is provided in the sealing groove, effectively preventing gaps in the seal caused by improper installation of the integral elbow during insertion, which would affect the sealing performance between the integral elbow and the plug housing.

The utility model belongs to the field of water dispensers, and provides a multifunctional electric valve structure assembly which comprises a machine shell provided with a containing cavity. The valve element fixed ceramic chip is installed in the containing cavity, and a water through hole is formed in the valve element fixed ceramic chip; the driving module is arranged on the machine shell, a valve element movable ceramic chip is connected to the driving module, the valve element movable ceramic chip stretches into the containing cavity and movably abuts against the valve element fixed ceramic chip, and a water supply hole is formed in the valve element movable ceramic chip. Compared with the prior art, the utility model has the advantages that a driving mode of the driving motor is adopted, so that the valve core movable ceramic chip is propped against the valve core fixed ceramic chip, corrosion and abrasion of impurities in water are effectively resisted, and the service life of the valve is prolonged; and meanwhile, the overlapping area between the water supply hole and the water through hole can be adjusted under the relative rotation of the valve element and the movable ceramic chip, so that the accurate control over the water outlet amount is achieved, and the flow requirements in different scenes are met.

A liquid-prevention structure includes a conversion connector, interface pipes, and a valve-type check valve. The conversion connector is a hollow shell structure with a necked interface at one end and multiple interface pipes spaced apart at the other end. The interface pipes are connected unidirectionally to the inner cavity of the conversion connector via the valve-type check valve. The valve-type check valve includes a valve body with both ends sealed to the interface pipes and the conversion connector, respectively. Two channels penetrating the valve body are symmetrically arranged on one end of the valve body. An installation arm is provided between the two channels at the end of the valve body facing the conversion connector. The surfaces of the two valve flaps facing away from the valve body channels are provided with limiting structures to prevent the two valve flaps from colliding. Compared with traditional ball-type check valves, this invention provides surface contact between the valve flaps and the valve body channel ports, resulting in better sealing, less wear, and a longer service life.

The utility model relates to chemical explosion -proof storage tank technical field, concretely is a kind of chemical explosion -proof storage tank, including collection jar, closure lid and cooling device, closure lid is installed on the top end of collection jar, cooling device is set on the bottom end of collection jar, cooling device includes heat conduction column, and the inside fixed connection of collection jar is connected with heat conduction column, and the inside of heat conduction column is placed with isolating sleeve, and the bottom end of isolating sleeve is equipped with air inlet, and the inside fixed connection of isolating sleeve is connected with drive motor, and the drive end fixed connection of drive motor has fan blade, and fan blade is located in the inside of isolating sleeve, and the outside of isolating sleeve is equipped with air outlet, and air outlet is communicated with the inside of isolating sleeve, and the bottom end fixed connection of drive motor has battery, and battery is located in the inside of isolating sleeve.The utility model, by setting cooling device, can effectively cool storage tank, avoid the temperature influence chemical product in the inside of storage tank, and then reduce the situation that storage tank appears explosion.

This invention discloses a sediment interception device for cast-in-place pile boreholes, comprising: a cover body with a pipe extending through its top; a partition plate disposed within the cover body; two mud pipes, both extending through the partition plate; two pneumatic components, both fixedly mounted on the top of the cover body; and two sealing components connected to the two pneumatic components respectively. This invention enables the pneumatic components to drive a sleeve rod to descend and rotate, thereby causing a connecting plate, plug, and rubber strip to descend and rotate. The rotating rubber strip pushes away sediment from the inner surface of the upper end of the mud pipe, thus cleaning the inner surface. When the rubber ring enters the mud pipe, it seals the mud pipe. Because the upper end of the mud pipe is cleaned, small stones can prevent them from affecting the sealing performance of the rubber ring.
