Description

Integrative dual-purpose type valve internal thread valve rod of polyurethane foam gap filler barrel

Technical Field

The utility model belongs to the technical field of the valve, concretely relates to valve rod for polyurethane foam gap filler.

Background

There are two types of existing polyurethane foam caulk flow tubes on the market (figures 1 and 3). Fig. 1 shows a general flow guide tube, which is mainly used for the tubular valve shown in fig. 2, and the main principle is that an internal thread is processed on a flaring sleeve of the flow guide tube and is screwed and butted with the thread of the tubular valve. This form is convenient to use, but has a number of disadvantages: for example, the amount of the sprayed material is large, the forward effect of the polyurethane foam gap filler is not ideal, the spraying flow is not controlled well in operation, and the like.

In order to solve the problems of the connection between the flow guide tube and the valve shown in fig. 1 and 2, the utility model with two publication numbers CN 203560539U and CN205288874U respectively proposes the flow guide tube shown in fig. 3 and the integrated dual-purpose valve shown in fig. 4. The structure of the gun type and tubular polyurethane foam gap filler is integrated by the added flow guide inner tube, so that the use is convenient; the honeycomb duct adopts the mounting means of cartridge, and convenient to use is swift. However, in the actual use process, the flaring sleeve and the valve of the flow guide pipe are inserted, so that the sealing is not tight, and the joint mixture is easy to leak at the joint of the valve and the flow guide pipe.

SUMMERY OF THE UTILITY MODEL

The problem of the joint mixture is revealed easily at the junction of valve and honeycomb duct to the flaring cover and the valve of honeycomb duct adoption cartridge formula of in-process to the in-service use among the prior art for it is not inseparable to seal, provides integrative dual-purpose valve internal thread valve rod of polyurethane foam joint mixture barrel.

The integrated dual-purpose valve internal thread valve rod of the polyurethane foam caulking agent gun barrel is characterized in that the upper end of the valve rod is provided with a spray pipe joint, the lower end of the valve rod is used for being installed inside a polyurethane foam caulking agent container, and preferably, on the basis of the scheme, internal threads are machined on the spray pipe joint.

On the basis of the scheme, the outer part of the spray pipe joint is in a shape matched with the inner wall of the flaring sleeve.

Preferably, the external cross-sectional shape of the spout adapter is in the shape of a "figure eight".

The utility model has the advantages that:

the external screw thread of water conservancy diversion inner tube and the internal thread looks adaptation that the spray tube connects, through threaded connection's form, better connection is sealed, prevents to reveal the material.

Detailed Description

The technical solution of the present invention will be further explained with reference to the drawings in the embodiments of the present invention.

As shown in fig. 6, the polyurethane foam caulking agent barrel integrated dual-purpose valve internal thread valve rod, the upper end of the valve rod 8 is a spray pipe connector 81, the lower end 81 is used for being installed inside a polyurethane foam caulking agent container, and the spray pipe connector 81 is provided with internal threads.

As shown in fig. 5, the integrative dual-purpose type external thread honeycomb duct of polyurethane foam caulking agent barrel for being used with the integrative dual-purpose type valve internal thread valve rod of polyurethane foam caulking agent barrel cooperation includes being responsible for 1, has cup jointed a water conservancy diversion inner tube 2 at the lower extreme of being responsible for 1, on being responsible for 1's lateral wall, encircle water conservancy diversion inner tube 2 and downwardly extending is formed with flaring cover 3, is formed with the grafting space between the inner wall of flaring cover 3 and the outer wall of water conservancy diversion inner tube 2, and the lower tip of water conservancy diversion inner tube 2 exposes in flaring cover 3, its characterized in that, the lower tip processing of water conservancy diversion inner tube 2 has the external screw thread.

The external screw thread of water conservancy diversion inner tube 2 and the internal thread looks adaptation of spray tube joint 81, through threaded connection's form, better connection is sealed, prevents to reveal the material.

The form of processing the screw thread inside spray pipe joint 81 is adopted, and for externally processing the external screw thread, the internal screw thread with a longer length can be processed, the length and the area of threaded connection are increased, and the sealing performance is better.

The outer part of the spray pipe joint 81 is in the shape matched with the inner wall of the flaring sleeve 3. The spray pipe joint 81 is positioned in an inserting space formed between the inner wall of the flaring sleeve 3 and the outer wall of the flow guide inner pipe 2, the two are in interference fit, the sealing effect is also achieved, and the two are in threaded connection and sealing to form a two-way sealing structure, so that the sealing is good.

Valve stem 8 is installed in a polyurethane foam caulk container during use, with spout adapter 8 exposed to the exterior of the container and lower end 81 located within the interior of the container.

The flaring sleeve 3 can be designed according to the actual situation, wherein the preferred section shape is in a shape of Chinese character 'ba'.

In order to operate the guide pipe conveniently, an operating handle 5 is further formed on the main pipe 1; in order to expand the application range of the draft tube, an extension tube 6 is connected to the upper end of the main tube 1.

It is to be understood that although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
