The invention relates to a water mixing valve comprising a valve body, a nozzle, a hot water regulating cavity, a water mixing cavity and a double-linkage valve, wherein the valve body is provided with a valve body cooling water inlet, a valve body hot water inlet and a valve body water outlet; the nozzle is communicated with the valve body cooling water inlet and provided with a nozzle cooling water inlet and a nozzle cooling water outlet; the valve body is internally provided with the hot water regulating cavity connected with the valve body hot water inlet and the water mixing cavity connected with the valve body water outlet; the water mixing cavity is connected with the hot water regulating cavity through a valve body hot water outlet positioned on one end of the hot water regulatingcavity and is also connected with the nozzle through the nozzle cooling water outlet; and the double-linkage valve is arranged above the hot water regulating cavity and the water mixing cavity and used for controlling the water discharge of the hot water regulating cavity and the water mixing cavity. The water mixing valve can be used for more flexibly regulating the water mixing proportion of cold and hot water so as to ensure that the water mixing and discharging effects of the valve is better.

[Problem] To reduce the amount of ethylene glycol which is produced as a by-product, to achieve a balance between productivity and properties such as water absorbency, and to reduce the number of defective goods when manufacturing a water-absorbent resin, particularly a resin which is surface crosslinked using an alkylene carbonate compound. [Solution] A manufacturing method for a polyacrylic acid (salt)-based water-absorbent resin powder, said method being characterised in that in the surface crosslinking step, a mixing process in which (1) a surface crosslinking agent containing an alkylene carbonate compound and a polyhydric alcohol compound is mixed with a water absorbent resin powder and thermally reacted, and an ionic reactive surface crosslinking agent is mixed with said mixture at either the same time, or separately from the above mixing, and / or (2) a surface crosslinking solution containing at least one kind of ionic reactive surface crosslinking agent is mixed with the water-absorbent resin powder, said mixing process being carried out at least two times.

The invention discloses a load self-adaptation gas-fired device of a gas engine. The load self-adaptation gas-fired device of the gas engine comprises an air channel, an air inlet, a gas channel, a gas inlet, a mixed gas channel, a mixed gas outlet, an upper diaphragm assembly, a lower diaphragm assembly, a gas chamber, a mixed gas chamber and an air chamber, wherein the gas chamber and the mixed gas chamber are separated by the upper diaphragm assembly, the air chamber and the mixed gas chamber are separated by the lower diaphragm assembly, the upper diaphragm assembly and a lower piston are fixedly connected into a whole through an adjusting threaded rod, the lower diaphragm assembly and an upper piston are fixedly connected into a whole through a pressure plate, metering holes are formed in a piston sleeve, and are used for input of air and gas and output of mixed gas, the metering holes are in a plugged or an open state along with movement of a piston head, and the upper diaphragm assembly and the lower diaphragm assembly can move vertically along with changes of air pressure, and drive the upper piston and the lower piston to move perpendicularly, so that the size of the air metering hole and the size of the gas metering hole are changed. The load self-adaptation gas-fired device of the gas engine can automatically provide the mixed gas with the appropriate amount according to the requirement of the gas engine, and can also automatically adjust the concentration of the mixed gas according to the requirement of load changes so that the purpose of improving power performance of the gas engine and the purpose of saving energy can be achieved.

The invention discloses a pressure-air fire fighting foam device for vehicle-carrying in the fire-fighting safety facilities technique domain, which comprises the following parts: water pump, bipeltate liquid container, air compressor, wherein the air feed end of air compressor connects to admission port of bipeltate liquid container through valve controlling conduit line; the bipeltate liquid conduit line form the exit of bipeltate liquid container passing through valve controlling conduit line and pressure pipe line from water pump conduit line passing through valve controlling conduit line converge for water bipeltate mixing flow conduit line; the compressed air conduit line form air feed end of air compressor passing through valve controlling conduit line and water bipeltate mixing flow conduit line converge for compressed air bipeltate liquid conduit line connecting to fire-fighting spraying device. The invention realizes that the compressed air bipeltate mixes free, which possesses steady system pressure.
