Another purpose of the present utility model is that interchangeable has feed liquor valve partly at least, and other part can obtain reusing many times, has reduced the cost that uses foam tool widely, and it is simple in structure, and is easy for installation, is fit to produce in enormous quantities.

In order to realize the foregoing invention purpose, the utility model adopts following technical scheme: it comprises housing, connector, feed liquor valve, liquid valve and switching device, switching device can make liquid valve open or cut out, and it is characterized in that described feed liquor valve and housing and/or connector make the branch body structure; Also comprise between feed liquor valve and connector or the housing sealing device is set.

Described sealing device comprises at least one seal.

The locking mechanism that can separate or lock the feed liquor valve is set between described feed liquor valve and housing or the connector.

Described feed liquor valve comprises liquid inlet port, seal and spring assembly.

The locking mechanism that can separate or lock liquid inlet port is set between described liquid inlet port and housing or the connector.

Described locking mechanism comprises at least one screw piece.

Described locking mechanism also comprises at least one screw hole or shrinkage pool.

Adopt the utility model of technique scheme, solved that the feed liquor valve breaks down or seepage or clogging easily in the foam tool, prolonged the service life of foam tool, saved resource widely, simple in structure, rationally, easy for installation, be fit to produce in enormous quantities.

The specific embodiment

A kind of foam tool of the present utility model, it comprises housing 1, connector 2, feed liquor valve 3, liquid valve 4 and switching device 5, switching device 5 can make liquid valve 4 open or cut out, and it is characterized in that: described liquid valve 4 can be made into the branch body structure with housing 1 and/or connector 2; Also comprise between feed liquor valve 3 and connector 2 or the housing 1 sealing device 6 is set.

Feed liquor valve 3 can comprise liquid inlet port 31, closure member 32 and spring assembly 33.

Liquid valve 4 can comprise fluid mouth 41, spool 42 and spring assembly 43.Can also comprise seal 44.

Referring to Fig. 1 and Fig. 3, liquid valve 3 is made the branch body structure with housing 1 and connector 2, between feed liquor valve 3 and the connector 2 sealing device 6 is set, and also can be between feed liquor valve and the housing sealing device to be set, and is used for preventing occurring between them the seepage phenomenon.Sealing device 6 can comprise seal 61 (or 62), and connector 2 also can be made branch body structure (referring to Fig. 3) with housing 1.Feed liquor valve 3 spins mutually by screw thread with connector 2 and housing 1 and links together.Also can be that feed liquor valve 3 is made the branch body structure with housing 1; Also can be that feed liquor valve 3 is made the branch body structure with connector 2.
