Abstract
The utility model discloses a polyamine ester foam gap filler valve which belongs to the technical field of pressure tank. The polyamine ester foam gap filler valve comprises a discharge pole, a rubber seat and an iron cup. A discharge hole is arranged at the center of the discharge pole. A limiting platform is arranged in the middle of the discharge pole. The lower part of the discharge pole is provided with a base and a discharge outlet which extends from the discharge pole side wall to the discharge hole. The rubber seat is sheathed on the discharge pole. The upper and lower two ends of the rubber seat separately contact with the base and the limiting platform. The iron cup is arranged at the outside of the rubber seat. The part of the discharge pole between the limiting platform and the base is provided with a step which has a big diameter on the upper part and a small diameter on the lower part. The rubber seat is matched with the discharge pole on the upper part of the step by a surface contact mode. The rubber seat is contacted with the discharge pole on the lower part of the step by a line contact mode towards the circumference. The rubber seat both on the upper side and the lower side of the contact line tilts outwards. The utility model has a small off-valve resistance force and a fast off-valve speed. The polyamine ester foam gap filler valve is not easy to leak materials; the polyamine ester foam gap filler valve is easy and reliable to use and is applied to encapsulate the pressure tank of the polyamine ester foam gap filler.
Description
Technical field
The utility model relates to a kind of eduction gear of head tank, belongs to the head tank technical field.
Background technology
In the prior art, a kind of Polyurethane foam gap filler (sizing material) is arranged, this Polyurethane foam gap filler is encapsulated in the head tank, head tank is provided with valve, described valve is made up of discharging rod, rubber base, iron cup etc., and the discharging rod center is provided with discharge opening, and the discharging rod middle part is provided with a spacing platform, the discharging rod lower end is provided with a base, and the discharging rod lower end also is provided with the discharging opening that extends to discharge opening from the discharging rod sidewall; Rubber base is socketed on the discharging rod, and rubber base up and down two ends is conflicted respectively on base and spacing platform, and the discharging rod even thickness between base and the spacing platform matches between rubber base and the discharging rod, and the iron cup is arranged at the periphery of rubber base; When sealed cans, with special-purpose sealing equipment iron cup and tank body are tightly connected, in use, push away discharging rod downwards with external force, base and rubber base are broken away from, and the Polyurethane foam gap filler in the tank body enters discharging opening from the gap location between base and the rubber base, discharge from discharge opening through discharging opening again, use for the user; Its weak point is: owing to have bigger face contact between discharging rod and the rubber base, friction force is bigger each other, and valve speed is closed in influence, closes valve speed and causes easily slowly and run the material phenomenon, can make the valve knot extremely, can't use; Thickness is consistent up and down with the contacted discharging rod of rubber base, and sizing material is also run out with the place that the rubber base top contacts from spacing platform easily when playing glue.
The utility model content
The purpose of this utility model provides a kind of Polyurethane foam gap filler valve, makes it be difficult for running material, and valve can not tied extremely, uses more reliable.
The purpose of this utility model is achieved in that a kind of Polyurethane foam gap filler valve, comprise discharging rod, rubber base, iron cup, the discharging rod center is provided with discharge opening, the discharging rod middle part is provided with a spacing platform, the discharging rod lower end is provided with a base, and the discharging rod lower end also is provided with the discharging opening that extends to discharge opening from the discharging rod sidewall; Rubber base is socketed on the discharging rod, rubber base is conflicted respectively on base and spacing platform at two ends up and down, the iron cup is arranged at the periphery of rubber base, also be provided with the step that a upper diameter is big, lower diameter is little on the discharging rod between described spacing platform and the base, contact for the face that cooperatively interacts between the discharging rod on rubber base and step top,, all outward-dipping between the discharging rod of rubber base and step bottom at the rubber base of the upside of contact wire and downside for circumferential line contacts.
The friction force that reduces between discharging rod and the rubber base is to improve the key of closing valve speed, the utility model is provided with the step that a upper diameter is big, lower diameter is little on the discharging rod between spacing platform and the base, the part that diameter is big contacts with the rubber seat surface, has good directional tagging, contact for line between the little part of lower diameter and the rubber base, the whole contact surface of discharging rod and rubber base is less, make the friction force between discharging rod and the rubber base less, it is little to close the valve resistance, it is fast to close valve speed, it is also little to open the valve resistance simultaneously, uses convenient; During use, with the oral area of the utility model sealing and fixing at head tank, pressing down discharging rod breaks away from base and rubber base, the Polyurethane foam gap filler that is encapsulated in the pressure filling is entering discharging opening from the slit between base and the rubber base under the interior pressure effect, be extruded from discharge opening again, use for the user, remove the external force that acts on the discharging rod, in pressure is irritated under pressure and the effect of rubber base screen resilience, rubber base contacts with base rapidly and compresses mutually, the Polyurethane foam gap filler and the discharging opening that make pressure irritate interior are isolated, because it is fast to close valve speed, make it be difficult for running material, the step in the middle of the discharging rod also can stop the Polyurethane foam gap filler to leak out between rubber base and spacing platform simultaneously, thereby uses more reliable.The utility model can be applicable to encapsulate on the head tank of Polyurethane foam gap filler.
Play the variation of glue mode when using, on the discharging rod on spacing platform top outside thread can be set, in use can be used with extension spray lance for adapting to; Also outside thread can be set, and directly play glue with the glue rifle.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 outside thread, 2 discharging rods, 3 spacing platforms, 4 rubber bases, 5 iron cups, 6 steps, 7 discharging openings, 8 bases, 9 discharge openings.
The specific embodiment
As figure, Polyurethane foam gap filler valve mainly is made up of discharging rod 2, rubber base 4, iron cup 5 etc., discharging rod 2 centers are provided with discharge opening 9, discharging rod 2 middle parts are provided with a spacing platform 3, discharging rod 2 lower ends are provided with a base 8, and discharging rod 2 lower ends also are provided with the discharging opening 7 that extends to discharge opening 9 from discharging rod 2 sidewalls; Rubber base 4 is socketed on the discharging rod 2, rubber base is conflicted respectively on base 8 and spacing platform 3 at two ends about in the of 4, iron cup 5 is arranged at the periphery of rubber base 4, also be provided with the step 6 that a upper diameter is big, lower diameter is little on the discharging rod 2 between spacing platform 3 and the base 8, contact for the face that cooperatively interacts between the discharging rod 2 on rubber base 4 and step 6 tops,, all outward-dipping between the discharging rod 2 of rubber base 4 and step 6 bottoms at the rubber base 4 of the upside of contact wire and downside for circumferential line contacts; The discharging rod 2 on spacing platform 3 tops is provided with outside thread 1.
