Description

Technical Field

[0001] The utility model relates to the technical field of positive foaming glue valves, in particular to a positive foaming glue valve device. Background Art

[0002] The existing foam rubber valve is a device used to control the sealing of the foam rubber tank and the spraying of the foam rubber. It is usually composed of a valve body, a valve stem, a rubber sealing pad, etc. By pressing the valve stem, the rubber pad valve stem drives the rubber sealing pad to compress, and the rubber pad is exposed through the valve stem outlet hole. The colloid enters the valve stem hole under the pressure in the bottle and is ejected. The rubber pad plays a rebound role to ensure that the pressing action ends, the valve stem returns to its original position, the rubber pad and the lower end of the valve stem block the valve stem hole, and a closed environment is formed in the bottle again.

[0003] At present, the application of this foaming glue valve structure requires the bottle to be inverted, with the pressure at the bottom of the bottle on top, and the glue flow rate is controlled by releasing the valve. It is inconvenient to hold the bottle when it is inverted for glue application. During construction, the gap is higher than the human body, so it is necessary to climb a ladder to apply glue. The construction space is also limited by the height of the ceiling and the bottle itself. It is urgent and inconvenient. The existing solution is to connect a funnel bottom probe device under the valve so that the colloid in the upright bottle can also be sucked out through the bottom probe, thereby achieving upright glue application. However, most of the funnel devices connected under the valve do not meet the sealing requirements at the connection, resulting in air leakage. Insufficient pressure will affect the upright effect, so a positive foaming glue valve device is proposed. Utility Model Content

The funnel-shaped valve rubber pad increases the sealing effect, solves the problems of air leakage and pressure reduction caused by the external funnel under the valve, and the bottom-probing guide tube realizes the infusion of foaming glue raw materials and the suction of glue liquid, thereby achieving positive foaming of the foaming glue bottle.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a positive foaming rubber valve device, comprising a rubber pad upper tube, wherein the outer wall of the rubber pad upper tube is provided with a mounting mechanism;

[0006] The mounting mechanism includes a first rubber pad sealing seat fixedly mounted on the bottom outer wall of the rubber pad upper tube, a funnel-shaped valve rubber pad fixedly mounted on the bottom outer wall of the first rubber pad sealing seat, a second rubber pad sealing seat fixedly mounted on the bottom outer wall of the funnel-shaped valve rubber pad, a raised ring of the rubber pad lower tube fixedly mounted on the bottom outer wall of the second rubber pad sealing seat, a valve stem is sleeved on the inner circumferential wall of the rubber pad upper tube, a valve stem sealing block is fixedly mounted on the outer circumferential wall of the valve stem, a valve stem lower sealing block is fixedly mounted on the bottom outer wall of the valve stem sealing block, a valve sealing ring is sleeved on the outer circumferential wall of the rubber pad upper tube, and a bottom exploration guide tube is sleeved on the inner circumferential wall of the raised ring of the rubber pad lower tube.
