Problems solved by technology

[0004] Aiming at the deficiencies in the tank mouth valve used for polyurethane foam caulking agent tanks in the prior art, the purpose of the present invention is to provide a tank mouth valve suitable for polyurethane foam caulking agent tanks with a new structure to solve the problems of the prior art. The tank body and the tank mouth valve of the polyurethane foam caulking agent tank can not be reused, resulting in great waste, and serious air pollution caused by recycling tank metal.

Embodiment 1

[0026] The tank mouth valve that is applicable to the polyurethane foam caulking agent tank of present embodiment, its structure is as follows figure 1 , image 3 and Figure 4As shown, it includes the tank mouth card joint fixedly installed on the tank mouth 8, the valve seat 3 made of elastic rubber installed in the tank mouth, and the valve seat 3 installed in the valve seat tube cavity and made of engineering plastics. The upper end is open and the lower end is closed. The valve stem tube 2, the joint head 1 processed by engineering plastics and the gasket 4 made of engineering plastics between the joint head and the valve seat are clamped on the tank mouth snap joint and connected with the spray gun joint. The upper and lower ends of the valve stem tube are designed with shoulders for clamping the two ends of the valve seat cavity wall, and the valve stem tube wall near the sealing end is designed with an opening for caulking agent to enter the valve stem cavity. It fo...

Embodiment 2

[0029] This embodiment is applicable to the tank mouth valve of polyurethane foam caulking agent tank, and its structure is as follows figure 2 , image 3 and Figure 4 As shown, the tank mouth valve structure is basically the same as that in Embodiment 1, the difference is that the valve seat 3 is a combined structure, and the valve stem tube mounting seat used as the valve seat body made of elastic rubber is located on the valve stem tube. The sealing seat 10 made of engineering plastics and the sealing member 9 installed in the sealing seat supported by the lower support structure of the cartridge under the mounting seat are made of rubber material compatible with the polyurethane foam caulking agent in the tank. It is designed with a support ring embedded in the support structure formed by the upward turning of the lower end of the cartridge, a guide cylinder for guiding polyurethane foam caulking agent into the cavity of the valve stem, and a mounting ring on which the ...

Abstract

The invention discloses a tank opening valve applicable to a polyurethane foam sealant. The tank opening valve comprises a tank opening clamping and connecting head, a valve seat, a valve rod pipe and a coupling head, wherein the tank opening clamping head is fixedly arranged on a tank opening; the valve seat is arranged in the tank opening and is made of rubber; the valve rod pipe is arranged in a pipe cavity of the valve seat, is made of hard materials, is opened at the upper end and closed at the lower end; the valve rod pipe and the tank opening clamping head are clamped and coupled at the tank opening; the coupling head is clamped and coupled at the tank opening clamping and connecting head and is coupled with a spraying gun joint; at least two axial opening grooves and reinforcing lug rings are designed on the coupling head; the axial opening grooves penetrate through the coupling head, contain opening walls and are opened at the lower ends; the reinforcing lug rings correspond to the opening grooves; the tank opening clamping and connecting head comprises a metal thin-wall cup-shaped clamping barrel and a clamping ring; the metal thin-wall cup-shaped clamping barrel is lined and attached in the tank opening; and the clamping ring is clamped at the edge of the tank opening and is made of hard materials. The tank opening valve disclosed by the invention not only can be firmly arranged on the tank opening, but also can be very convenient to be taken down from the tank opening, and completely solves the problems that the tank opening valve cannot be taken down from the tank opening to enable a tank body and the tank opening valve not to be recycled for repeated use and further waste and air pollution are caused by recycling the metal of the tank body and burning the tank body in the prior art.

Description

technical field [0001] The invention relates to the technical field of polyurethane foam caulking agent commodity packaging, and more specifically relates to a tank mouth valve matched with a polyurethane foam caulking agent tank. Background technique [0002] Polyurethane foam sealant is an indispensable building material in house construction and decoration. The manufacturer, subpackager or builder fills the polyurethane foam sealant into the bottle used on the construction site and closes it with the tank valve When using the tank mouth, connect the sealant spray gun to the tank mouth valve, so that the polyurethane foam sealant in the tank communicates with the spray gun, and inject the polyurethane foam sealant into the wall joint through the spray gun. The amount of polyurethane foam caulking agent is very large. In recent years, the amount of filling caulking agent used is more than 100 million cans per year, and the annual usage is close to 200 million cans. [0003...
