Description
Technical field
The present invention relates to a kind of rubber injecting valve, particularly a kind of non-contact rubber injecting valve that is used for accurate injecting glue, this rubber injecting valve is applicable to the accurate injecting glue of various fluids such as epoxy resin, instant drying adhesive, anaerobic adhesive.
Background technique
Rubber injecting valve is a vitals in the glue filling device, and it can realize that by the ON/OFF control of valve convection current goes out colloid and controls.Existing injecting glue mode is the contact-type injecting glue, adopt the rubber injecting valve parts of this injecting glue technology directly to contact with feed liquid, can rub between the particle in the feed liquid and the critical piece of rubber injecting valve, not only influence the accuracy of injecting glue, also shorten the working life of rubber injecting valve greatly.The parts of rubber injecting valve directly contact with feed liquid simultaneously, and the cleaning of rubber injecting valve is very inconvenient.
The existing contact valve mainly contains plunger type rubber injecting valve, striker formula rubber injecting valve and diaphragm type rubber injecting valve.The plunger type rubber injecting valve is to utilize the motion of plunger to realize the switch of valve, the rubber injecting valve of this structure needs the back and forth movement of plunger, the front end and back end sealed department of plunger and valve body easily produces friction and causes wearing and tearing, causes can't sealing of these positions, and then produces leakage glue.When throttle down, enter cylinder because the extruding feed liquid may spill from the rear end of valve body, thereby damage rubber injecting valve.
Striker formula rubber injecting valve mainly is the effect of playing the switch injecting glue by striker bump striker seat.This rubber injecting valve is because the friction between striker, striker seat and the feed liquid very easily damages striker.In addition, frequent injecting glue action then can make the endoporus wearing and tearing of striker sealing gasket, thereby reduce its sealing.
The diaphragm type rubber injecting valve utilizes barrier film to realize the valve switch action.The diaphragm seal valve head of this rubber injecting valve is very thin, and the injecting glue action can cause it to rupture for a long time.Barrier film and valve head are one, and are macromolecular material, make difficulty of processing big, the cost height.
