The invention relates to an anti-overflow non-flameout device which can solve the problems that petroleum in an oil-gas separator adopting a heating furnace to provide natural gas is excessive and overflows from a top natural gas pipeline, the natural gas pipeline is blocked by the petroleum and heating of crude oil is affected. The scheme is as follows: the anti-overflow non-flameout device comprises a truncated cone-shaped sleeve which is arranged in the positive direction in a gas outlet at the top end of the oil-gas separator, the outer edge of a small circular surface at the top end of the sleeve is hermetically connected with the inner edge surface of the gas outlet, a gap exists between the outer edge of a large circular surface at the lower end of the sleeve and the inner edge surface of the gas outlet, a blocking piece extending into the truncated cone-shaped sleeve is fixedly arranged on the circumference on the lower end surface of the sleeve, an isolation plate is arranged in the sleeve, the lower end of the isolation plate is connected with a floating ball arranged below the sleeve through a connecting rod, and a plurality of ventilation circular holes are uniformly distributed on the circumference at the top of the side surface of the sleeve. The anti-overflow non-flameout device provided by the invention can prevent a large amount of petroleum from overflowing into other devices from the natural gas pipeline at the upper part of the truncated cone-shaped sleeve, and can ensure that natural gas enters the pipeline from the circular holes at the top of the truncated cone-shaped sleeve so as to ensure the normal operation of production.

The invention relates to a constant-flow type electromagnetic auxiliary heating device of a water heater. The constant-flow type electromagnetic auxiliary heating device comprises a main control board, a water-cooling radiating pipe, a heating inner container and a control panel. A water inlet pipe is connected to one end of the water-cooling radiating pipe and sequentially connected with a water flow switch and a constant-flow directional control valve to be communicated with the water-cooling radiating pipe, and the other end of the water-cooling radiating pipe is connected with the heating inner container. The heating inner container comprises a ceramic tube and an electromagnetic coil, the upper end of the ceramic tube is an upper sealed end, and the lower end of the ceramic tube is a lower sealed end. A low-temperature water pipe and a hot water pipe are arranged at the upper sealed end, the low-temperature water pipe outwards extends from the upper sealed end to pass through a first temperature sensor to be then communicated with a low-temperature water inlet pipe, and a second temperature sensor is electrically connected with the control panel. The main control board is electrically connected with the control panel. By means of the constant-flow type electromagnetic auxiliary heating device, the structure of an existing water heater does not need to be changed, multiple restraining factors of the existing water heater in use are overcome, multi-energy-source optimized combining is achieved, and low-temperature hot water is comfortably used in the most economical and most energy-saving mode.

The invention relates to the technical field of medical detecting and cleaning equipment and discloses a cleaning device used for a clinical laboratory. A cleaning box is included, and a motor is fixedly installed at the bottom of one side of the cleaning box, and is fixedly installed in a box body; an output shaft of the motor extends to the exterior of the bottom end of the box body, and is fixedly sleeved with a coiling block I; the middle portion of an inner cavity of the cleaning box is movably sleeved with a rotating shaft I, and one end of the rotating shaft I extends to the exterior ofthe bottom end of the cleaning box, and is fixedly sleeved with a coiling block II; and the outer wall of the coiling block II is in transmission connection with the outer wall of the coiling block Ithrough a belt. According to the cleaning device used for the clinical laboratory, by arranging an installing box, a glass test tube, a support, rotating shafts, a clamping plate and a balance block,the effect of clamping the glass test tube can be achieved; and when the glass test tube is clamped, the interior of the glass test tube can be conveniently cleaned, it is guaranteed that the interior of the glass test tube can be cleaned better, and meanwhile the situation that the glass test tube fractures in the cleaning process is avoided.

The invention discloses a novel multifunctional water dispenser, which comprises a display screen, a hot water faucet, a water storage groove, a water bucket, a front door, an observing opening, a cold water faucet, a housing, a first water pump, a water pumping pipe, sliding wheels, a rear door, a plug, a second water pump, a heat-insulating box, a temperature sensor, a water level sensor, a water boiling box, a cold water pipe, a heating pipe, a connecting pipe and a rubber plug. The water dispenser provided by the invention has the beneficial effects that by adopting a mode of arranging the water bucket on the lower side, the phenomena that a conventional water dispenser, which is provided with the water bucket on the upper side, is inconvenient to mount, capable of causing water leakage easily and capable of causing breakage of a connector easily can be effectively prevented; with the adoption of a mode of using the heat-insulating box and the water boiling box together, the problems of the conventional water dispenser that sterilizing temperature for making tea is insufficient since boiling temperature of water is not high enough and called 'repeatedly boiling water' is supplied when warm water is repeatedly heated are solved; by arranging the rear door on the back side of the device (the water dispenser), the interior of the device can be cleaned conveniently, so that the easy accumulation of water scales and bacteria can be prevented; and the water dispenser is good in economic and social benefits and is suitable for popularization and application.

The invention relates to the technical field of municipal water supply equipment, in particular to a self-cleaning secondary water supply water tank for municipal water supply. The self-cleaning secondary water supply water tank comprises a main body and a motor, the main body comprises a water sump, the surface of the water sump is fixedly connected with a connecting port, the surface of the water sump is provided with a cleaning mechanism, the cleaning mechanism comprises a water storage tank, the surface of the water sump is fixedly connected with the water storage tank, the bottom end of the water storage tank is fixedly connected with a supporting frame, the surface of the water sump is fixedly connected with a motor, the inner side of the water sump is movably connected with a screw rod, and the inner side of the screw rod is sleeved with a cleaning plate. Through connection of a spray head and a connecting pipe, the spray head can conveniently clean the inner wall of the water sump, a worker does not need to enter the water sump for cleaning, the interior of the water sump is efficiently and timely cleaned, the position of a supporting block in the water sump can be conveniently adjusted, the inner wall of the water sump can be conveniently supported by an abutting plate, the internal pressure is prevented from being too large, and the use effect of the water sump is influenced.
