A back-pressure valve comprises a case having first and second oil chambers through which oil passes. A piston is slidably accommodated within the case to partition the first oil chamber and the second oil chamber. A spring urges the piston in a sliding direction. A projecting member and a check valve allow the first oil chamber to communicate with the second oil chamber when the pressure of the oil in the first fluid chamber reaches a predetermined pressure. An area of the piston on which oil pressure is received in the first oil chamber is made lager than an area on which oil pressure is received in the second oil chamber. A part of the piston located at an end thereof opposite to the end thereof which faces the first oil chamber communicates with the outside of the case.

A coating machine is capable of reducing VOC and CO2 by atomizing a paint to increase depositing efficiency without lowering production efficiency and the rotary atomizing head of the coating machine. The coating machine includes the rotary atomizing head in which a paint chamber receiving the supply of paint is formed on the rear side thereof. A plurality of rims formed in a roughly truncated conical shape for extending the paint flowing out of the paint chamber by a centrifugal force and atomizing the paint at the tip thereof are fitted in the rotary atomizing head overlappingly at specific clearances. The clearances are opened to the peripheral surface part of the paint chamber. Accordingly, VOC and CO2 can be reduced by reducing the total jetted amount of paint to enable the atomization of the paint at low rotating speeds so as the increase the deposit efficiency.

A method for altering the width of a strip-shaped rolled material (5), before, during or after hot rolling the rolled material in a hot rolling mill. The problem is to specify a method for altering width so that the length of a rolled out transition piece lying outside width tolerances can be reduced. Scrap losses are to be reduced. The crown of at least one working roll and / or at least one backing roll of a stand (7) is set as a function of a width error e=B−B between a setpoint width Bsetp and the width B of the rolled material (5), wherein the crown is increased when e>0 and the crown is reduced when e<0. AA Rcrown BB Bsetp.

A disclosed efficient fertilizer special for corn is prepared as follows: uniformly mixing pond trench mud, oil shale ash, ferrous sulphate, monoammonium phosphate, manganese sulfate, potassium chloride, zinc sulfate, a magnesium-potassium sulfate fertilizer, ammonium molybdate and attapulgite powder, so as to obtain a material A; adding animal hair into a sulfuric acid solution for hydrolysis, adding proper amount of calcium bicarbonate to adjust the pH value of the hydrolysis solution to be 6.75-6.83, then adding carboxymethylcellulose sodium and stirring uniformly to obtain a mixed solution, adding sweet potato powder, urea, dicyandiamide powder and polyvinyl alcohol into the mixed solution, and uniformly mixing to obtain a material B; and spraying the material B to the continuously-rotated material A, and pelleting to obtain the efficient fertilizer special for corn. The efficient fertilizer special for corn is capable of improving the lodging resistant capability of corn and satisfies various elements demands by corn growth, and the release speed accords with different demands of corn on nutrition elements at all growth periods, and also the efficient fertilizer special for corn is capable of improving the soil physical and chemical properties and increasing soil fertility.

The invention relates to a universal transportation table supporting arm mechanism for an engine cover. The universal transportation table supporting arm mechanism comprises installation frames, a supporting shaft, limiting block installation seats and limiting blocks. The supporting shaft is installed between the symmetric installation frames. The multiple limiting block installation seats are arranged on the supporting shaft from the part taking end to the part storing end, and the limiting blocks are installed in the limiting block installation seats one by one. The limiting block installation seats are arranged on the supporting shaft in an overturning type sliding and sleeving manner. Multiple pin holes are formed in the part taking end of the supporting shaft. A pin hole is formed in the limiting block installation seat at the part taking end. The limiting block installation seat at the part taking end and the part taking end of the supporting shaft are positioned through a lock pin. The universal transportation table supporting arm mechanism for the engine cover is scientific and reasonable in structural design, adjustability of limiting grooves can be achieved, meanwhile, due to the sequentially positioning type storing and taking operation of side limiting mechanisms, the storing and taking convenience of automobile accessories is greatly improved, universality is high, the use frequency of devices is improved, possible waste losses are reduced, the spare part circulation efficiency is improved, and spare part packaging, logistic cost and the like are optimized.

The invention discloses an equipment production line for self-heat-insulation building blocks for walls. The equipment production line comprises a hollow brick production system, a steam curing system, a transfer system, a foam concrete pouring system and an automatic control system. The steam curing system is respectively connected with the hollow brick production system and the foam concrete pouring system by the transfer system, and the automatic control system is connected with the hollow brick production system, the steam curing system, the foam concrete pouring system and the transfer system by control circuits. Compared with the traditional production line, the equipment production line has the advantages that the steam curing efficiency is greatly improved, the energy cost is greatly saved, and the production cost is reduced; and distances from a filling plate and a filling groove to hollow bricks can be adjusted via lifting mechanisms, so that slurry can be effectively prevented from flowing out of the hollow bricks during pouring when the quantity of slurry in the filling groove is excessively high, waste of the slurry is reduced, and accordingly the production cost is saved.
