The invention discloses a drain valve which comprises a button seat arranged on the upper end, a barrel body arranged in the middle and a base arranged at the bottom; a lifting pipe is arranged in the barrel body, and one side of the barrel body is also provided with an overflow pipe which is communicated with the base; the drain valve is also provided with a lever-type drain mechanism; the lever-type drain mechanism comprises a semi-drain mechanism and a full-drain mechanism; and the semi-drain mechanism and the full-drain mechanism are arranged inside and outside of the barrel body separately. The drain valve has the advantages of simple and reasonable structure, quite convenient installation and use, and can flexibly and greatly adjust the water drainage and save water resource. Because the product has small size and lower cost, and some structures are improved, the produce fault rate is lower, and the use of a user is easier.

The invention provides a self-induction type bubble enrockment submerged breakwater. The self-induction type bubble enrockment submerged breakwater comprises a breakwater base and is characterized in that the breakwater base is provided with an air compressor and an energy accumulator for supplying power, the air compressor is connected with an air inlet pipe and air exhaust pipes, the air exhaust pipes are vertically arranged on the breakwater base, the air inlet pipe is a flexible pipe, and the upper end of the air inlet pipe is connected with a detection buoy; the detection buoy comprises a buoy body, a wave height measuring device and a solar cell panel; and the signal output end of a wave meter is connected with a controller through a first cable, the controller is connected with the signal receiving end of the air compressor through a second cable, and the solar cell panel is connected with the energy accumulator through a third cable. According to the actual incident wave parameters, the size of wave energy can be analyzed, the wave absorbing control variable can be adjusted, then, the exhaust volume of the air exhaust pipes is adjusted, and an economical and effective wave absorbing effect is achieved.

The invention discloses a simulation experiment device for reaming gas reverse circulation through horizontally directional drilling, and an experiment method, and relates to the technical field of non-excavation engineering. According to the simulation experiment device for reaming gas reverse circulation through horizontally directional drilling, and the experiment method, an air storage tank isarranged on the right side of an air compressor, the right side of a pressure reducing valve is connected with an air inlet pipeline, and a motor is arranged below a vortex shedding flowmeter. According to the simulation experiment device for reaming gas reverse circulation through horizontally directional drilling, and the experiment method, the rock debris discharging process during gas reversecirculation reaming through horizontally directional drilling is simulated, by using the simulation experiment device for reaming gas reverse circulation through horizontally directional drilling, and the experiment method, the influences of different working flow pressure, annulus mud pressure and drilling rod rotating speeds on the working property and the cavitation property of a reamer can beresearched, and the influences of different mud properties, rock debris particle diameters, rock debris adding speeds and drilling rod rotating speeds on the debris discharging efficiency of the reamer can be further researched.

The invention relates to the technical field related to sanitary ware, and discloses a one-button toilet drain valve, which includes a toilet body on which a water tank cover, a water inlet valve, a drain valve, a single-key switch, a limit pipe and The installation pipe, the upper and lower ends of the middle part of the inner wall of the drain valve are movably equipped with a movable rod, and the bottom end of the movable rod is fixedly installed with a valve core, and the bottom end of the side wall of the movable rod is fixedly installed with a multi-row movement valve located above the valve core. block, the inner wall of the drain valve is eccentrically mounted with multiple rows of driving rods on one side of the movable rod. In the present invention, a few rows of drive rods and multiple rows of drive rods are provided on the drain valve, so that when flushing, the few rows of drive rods can be controlled by pressing the single-key switch to realize the discharge of less medium. The switch controls the multi-row driving rods to discharge all the media in the water tank, and then realizes the single-key control of the drainage, which is convenient for people to use, and finally achieves the purpose of single-key control of drainage.
