The invention relates to a polyurethane resin and fiber or solid particle mixing valve; a mixing valve body is internally provided with a master mixing channel, a small oil cylinder is arranged under the mixing valve body and is internally provided with a small piston which is provided with a small piston rod, the small oil cylinder is also internally provided with a polyurethane raw material mixing channel that is communicated and matched with the master mixing channel, the two sides of the polyurethane raw material mixing channel are provided with polyurethane raw material feeding holes, and a pressure adjusting valve is positioned between the polyurethane raw material feeding holes and the polyurethane raw material mixing channel; the left side of the mixing valve body is provided with a big oil cylinder which is internally provided with a big piston provided with a big piston rod, the left end of which is provided with a fiber and solid particle feeding hole, and the interior of the big piston rod is hollow to form a fiber and solid particle channel; and the big piston rod extends into the mixing valve body, and a fiber and solid particle channel feeding channel is communicated and matched with the master mixing channel. The mixing valve has good mixing effect, and ensures the products made of the materials mixed by the mixing valve to have higher strength and better performance.
Description
technical field [0001] The present invention relates to a mixing valve, more particularly, to a polyurethane and fiber or solid particle mixing valve. Background technique [0002] In manufacturing industries such as home appliances, refrigerators, furniture, automobiles and construction, polyurethane is widely used as insulation materials, cushions, furniture and decorations, etc. The currently used polyurethane foaming equipment is generally mixed by injecting the two liquid raw materials A and B of foamed polyurethane into the mixing channel in the mixing valve, and then injecting them into the mold cavity through the nozzle for foaming. However, due to the limitation of the performance of the polyurethane raw material itself, the processed products have deficiencies in strength and performance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a polyurethane and fiber or solid particle mixing valve with simple...
