Description
Technical field:
The utility model relates to glue valve technology field, refers in particular to the accurate glue valve of a kind of no cull centre lathe type.
Background technique:
Accurate glue valve is used in the glue dripping machine more, by the outflow of accurate glue valve control raw material.At present common accurate glue valve is a centre lathe type, the outlet of the shank control glue valve that this product is driven by piston by its inside, and it is applicable to the various plastic cement fluids that do not contain particle, and has plurality of advantages such as volume is little, in light weight.The main body of the accurate glue valve of common centre lathe type is made of two sections, and wherein piston needle valve is installed in top, controls moving of shank.The shank of piston needle valve inserts the bottom of main body, by needle tip material outlet is stopped up.Raw material is entered by the glue-feeder of lower body part, is flowing out by outlet.During use, drive shank, with the obstruction of control material outlet or open by piston needle valve.In order to guarantee that the raw material that flows as lower body part can not enter into top, binding site need seal between shank and the lower body part, normally adopts in lower body part and fixes a seal ring, and shank is worn seal ring.So just guarantee the hardwood shank in the process that moves back and forth, raw material can not leak to main body top with shank or other gaps.But this sealing configuration has the following disadvantages: because the continuous to-and-fro motion of shank, its wearing and tearing to seal ring are very large.So use the seal ring that just need more renew after a period of time, cause the large usage quantity of seal ring like this.In addition, because present glue valve can't be observed Lou glue situation, the user generally can only judge by experience.Usually just whole accurate glue valve is taken off the raw material that cleaning is leaked, and the seal ring that more renews after needing whole parts to use.
For this reason, the applicant is from reasonable, practical angle, creation designed a can the free adjustment seal ring, leak the accurate glue valve of the visual no cull centre lathe type of glue, to overcome above-mentioned problem.
Summary of the invention:
Technical problem to be solved in the utility model is to overcome the deficiency of present product, provide a kind of can the free adjustment O-ring seal, reliable, the long service life of sealability, be difficult for producing and leak, leak the accurate glue valve of the visual no cull centre lathe type of glue.
For solving the problems of the technologies described above, the utility model has adopted following technological scheme: this precision glue valve comprises the glue valve body and is installed on the interior piston needle valve of glue valve body, wherein main body is by the upper and lower, wherein piston needle valve is installed in the top, the shank portion of this piston needle valve inserts in the bottom, it is characterized in that: be movably installed with an adjustable sealing circle in the bottom of main body, the shank of piston needle valve passes this adjustable sealing circle.
Described adjustable sealing circle comprises: be set in adjusting knob and O-ring seal on the shank, adjusting knob is connected with the lower body part inner thread, and screws under the pressure at adjusting knob and O-ring seal to be pressed in the bottom in the wedged hole.
Offer adjustment hole in described adjusting knob circumference side, the position of corresponding adjustment hole offers breach on the sidewall of lower body part.
Between the upper and lower of described main body for being threaded.
With respect to present product, the utility model can the free adjustment O-ring seal, it is visual to leak glue, has overcome like this and has leaked the deficiency that glue is not visible, sealing is unadjustable.The utility model adopts simple structure to design the accurate glue valve of a kind of no cull centre lathe type, but its free adjustment O-ring seal, sealability are reliable, long service life, be difficult for producing leak, to leak glue visual.The utility model is widely used in industrial glue application, is particularly useful for the glue application technology of the production process of equipment such as loudspeaker, audio amplifier.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model cut-away view;
Fig. 2 be among Fig. 1 A-A to sectional drawing;
Fig. 3 be among Fig. 1 B-B to sectional drawing.
Embodiment:
See Fig. 1～3, the main body 1 of the accurate glue valve of this centre lathe type is made of for 12 two sections top 11 and bottom, between the top 11 of main body 1 and the bottom 12 by being threaded.In the top 11 of glue valve body 1, be provided with piston needle valve 3, the moving of this piston needle valve 3 control shanks 31,31 ones of the shanks of its piston needle valve 3 insert in the bottom 12 of main body 1, by 311 ones at needle point material outlet 124 are stopped up.Raw material is that the glue-feeder 123 by the bottom 12 of main body 1 enters, and is flowing out by outlet 124.
During use, drive shanks 31, with the obstruction of control material outlet 124 or open by piston needle valve 3.For the raw material of the bottom 12 that guarantees to flow into main body 1 can not enter into top 11, binding site need seal between the bottom 12 of shank 31 and main body 1, so be movably installed with an adjustable sealing circle 2 in the bottom 12 of main body 1, the shank 31 of this piston needle valve 3 passes this adjustable sealing circle 2.
Adjustable sealing circle 2 comprises: be set in adjusting knob 21 and O-ring seal 22 on the shank 31, adjusting knob 21 is connected with bottom 12 inner threads of main body 1, and in adjusting knob 21 screws bottom 12 interior wedged holes (122) that under the pressure O-ring seal 22 are pressed on main body 1 and tightly be attached on the shank 31.So just guarantee shank 31 in the process that moves back and forth, raw material can not leak to the top 11 of main body 1 with shank 31 or other gaps.Because the continuous to-and-fro motion of shank 31, its wearing and tearing to O-ring seal 22 are very large.So only adjusting knob 21 buttons tightly need be got final product after using a period of time, the O-ring seal 22 that need not more renew has so just prolonged working life of O-ring seal 22.
In sum, the utility model adopts simple structure, designs the accurate glue valve of a kind of no cull centre lathe type, to satisfy people's demand.The utility model its can the free adjustment O-ring seal, reliable, the long service life of sealability, be difficult for producing leak, to leak glue visual.
Certainly, the above only is the utility model example, be not to limit the utility model practical range, all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
