Description of drawings
Fig. 1 is the glue dispensing valve structural representation that the utility model embodiment is provided.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also Fig. 1, be the disclosed glue dispensing valve structural representation of the utility model embodiment,, only show the part relevant with present embodiment for the ease of explanation.Glue dispensing valve disclosed in the utility model; Comprise two spool 11, upper valve body lid 2, piston 8, upper valve body 9, middle valve body 13, following valve body 17 and following body caps 19 that structure is identical; Wherein, Upper valve body lid 2 is fixedly connected upper valve bodies 9, and upper valve body 9 is provided with an O type circle 4 with the installation position of upper valve body lid 2, and forms the zone of a sealing with piston 8; Piston 8, upper valve body 9, middle valve body 13, following valve body 17 and following body cap 19 are fixedly connected sequentially; Two identical spools 11 of structure run through piston 8, upper valve body 9, middle valve body 13 and following valve body 17 respectively successively; And the central axis along piston 8 is symmetrical set; The cross section of spool 11 is rounded; In the cavity that valve body 13 and following valve body 17 surrounded during its sealed end was arranged on, and the diameter of spool 11 sealed ends is less than the diameter of said spool 11 main bodys.Spool 11 is provided with one the 5th O type circle 10 with the inwall junction of piston 8.
Be fixedly connected an adjusting knob 1 on the upper valve body lid 2; Adjusting knob 1 is fixed on the upper valve body lid 2 through screw thread, and the 4th O type circle 10 and nut 5 is set on the adjusting knob 1, and nut 5 is arranged on the upper end surface near piston 8; Glue dispensing valve also is provided with a joint 3; Joint 3 connects a side of upper valve body lid 2, and the end face junction of valve body 13 and following valve body 17 is provided with the end face junction that the 2nd O type circle 14, the three O type circles 18 are arranged on down valve body 17 and following body cap 19 in said.One mixing tube installation sleeve 20 is fixedly connected body cap 19 down through screw thread.End face junction at middle valve body 13 and upper valve body 9 is provided with first sealing ring 12, and the end face junction of valve body 17 and middle valve body 13 is provided with second sealing ring 16.
The operation principle of the disclosed glue dispensing valve of the utility model embodiment is following: this glue valve uses moving up and down of cylinder control valve core, thereby realizes the break-make control of left and right sides runner.When feeding compressed air in the joint 3, piston 8 drives spool 11 under pressure and moves down, and the spool 11 and second sealing ring 16 form via fluid and can pass through; When the compressed air pressure of joint 3 reduced, piston 8 drove spool 11 under pressure and moves up, and spool 11 cooperates passageway shuts off with second sealing ring 16, and fluid (such as glue) can't pass through.
High-pressure fluid (like glue) through middle valve body 13 about two interfaces get into valve bodies, high pressure acts on respectively on the upper surface and lower surface of spool 11 because that the sealed end of spool 11 gets diameter is identical, the pressure that high pressure forms is equal, and is in the opposite direction, counteracted by pressure.Influence the system friction of having only of glue threshold switch, so between the higher pressure area that the disclosed glue valve of the utility model embodiment can be worked.
When the piston 8 of glue valve moved up, spool 11 moved up simultaneously, and the gap of the spool 11 and second sealing ring 16 diminishes up to closing gradually, and after runner was closed, spool 11 continued to move up, and received the obstruction of the nut 5 on the adjusting knob 1 up to piston 8.After runner was closed, piston 8 continued to move upward, and the volume of the runner cavity of valve body 17 diminishes under driving, and fluid is wherein moved upward with piston 8, and this effect has improved the disconnected glue ability of glue valve, reduces the wire drawing effect to some high viscosity glue.
Because adjusting knob 1 is installed in above the upper valve body lid 2 through screw thread; Can make through rotation adjusting knob 1 to be installed in top nut 5 and to move up and down, thus influence piston 8 in the position of glue valve nozzle upper end, turn clockwise on earth as reconciling knob 1; Adjusting knob 1 is close on the upper valve body lid 2; This moment, the resorption of glue valve was minimum, as was rotated counterclockwise on earth, and then the resorption of glue valve is the strongest.The 5th O type circle 10 above the adjusting knob not only can be used as static seal and prevents that gas from leaking simultaneously also the locking usefulness as adjusting knob.
Can find out that through above narration the glue dispensing valve that the utility model provides adopts the spool design scheme of reducing design when guaranteeing the disconnected glue effect of glue valve, to guarantee the reliability and the fast-response of the action under high pressure of glue valve.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
