Abstract

A non-rising valve for a plastic pipeline system comprises a plastic valve body, a valve core and a valve seat, wherein, the valve core and the valve seat are arranged in the valve body, and a water inlet and a water outlet are formed at two ends of the valve body. The non-rising valve is characterized in that the water inlet and the water outlet are connected with a plastic pipeline through hot melting; and split sockets used for the insertion of the plastic pipeline are respectively installed in the water inlet and the water outlet. The non-rising valve connected with the plastic pipeline through hot melting has simple structure and reliable connection, and can be dark buried together with the pipeline, which effectively overcomes the problems of the application of metal valves.

Description

The dark valve of plastic duct system

Technical field

The utility model relates to a kind of plastic pipe valve, the valve that relates to a kind of PP-R of being used for plastic duct system specifically and can secretly bury.

Background technique

In the PP-R pipe-line system owing to need control to current, as only open, operation such as control flow rate.So need be provided with valve by the PP-R pipeline.Because the PP-R pipeline need secretly bury processing, belong to concealed work, and traditional valve generally all is a Structural Hardware, and can not secretly buries processing with the PP-R pipeline, and and the PP-R pipeline all be the Placement that adopts machinery, connect and do not possess Security.So existing Structural Hardware valve generally is difficult to be applied in the buried PP-R pipeline.

The model utility content

Technical problem to be solved in the utility model is, overcomes problems of the prior art, provides a kind of plastic duct system dark valve.

In order to address the above problem the technical solution of the utility model is such:

The dark valve of plastic duct system comprises the plastics valve body, is arranged on spool, the valve seat of valve inner, the valve body two ends are provided with current and import and export, it is characterized in that described current are imported and exported and are connected by hot melting way with plastic pipe, are provided with the amalgamation socket that is used for the plastic pipe insertion in the import and export.

Described spool is connected with a valve rod, and described valve rod connects one handle.

Be connected by clamping bolt between valve rod and the handle.

Handle cover is stamped in described handle upper end.

During use, dark valve described in the utility model is connected with plastic pipe, and can secretly buries construction with plastic pipe by hot melting way.

Beneficial effect, the utility model adopt hot melting way to be connected with plastic pipe, and be simple in structure, connects reliably, and can secretly bury with pipeline, effectively overcome metal valve and used the problem that exists.

Description of drawings

Describe the utility model in detail below in conjunction with the drawings and specific embodiments;

Fig. 1 is the dark valve arrangement schematic representation of plastic duct system described in the utility model;

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Referring to Fig. 1, present embodiment is the dark valve of using in the PP-R pipe-line system, and dark valve comprises valve body 1, valve body 1 inner chamber is provided with valve seat 2, valve seat 2 tops are provided with the spool 3 that is mated, and in order to guarantee spool 3 hardness, spool 3 is a ceramic valve core, spool 3 connects a valve rod 4, valve rod 4 connects one handles 5, is connected by clamping bolt 7 between described valve rod 4 and the handle 5, and commentaries on classics is joined simply, and when a certain parts damages, can be convenient for changing.When turning handle 5, handle 5 can drive valve rod 4 and move up and down, and move up and down thereby valve rod 4 drives spool 3, and then control is by the fluid flow of valve body 1.

Because this dark valve is arranged in the PP-R pipeline that can secretly bury, so valve body 1 is PP-R plastics valve bodies, especially the import and export at valve body 1 two ends are necessary for the PP-R material, import and export inner chamber at valve body 1 two ends is provided with amalgamation socket 11, PP-R pipeline 12 can insert amalgamation socket 11, and the method by hot melt is connected the import and export of PP-R pipeline with valve body 1 two ends then.Plug together purpose in order to reach, the internal diameter of described amalgamation socket 11 is more than or equal to the external diameter of PP-R pipeline 12, so that PP-R pipeline 12 can insert in the amalgamation socket 11.

Because dark valve and PP-R pipeline all secretly bury with underground, handle cover 6 is stamped in described upper end at handle 5, to play the purpose of protection handle.

Valve body 1 is provided with the inside and outside spiral shell connecting sleeve 8 that cooperates with handle 5 in addition, and when handle with sleeve 5, handle 5 can be above-below direction relative to valve body and move, and moves up and down thereby drive valve rod 4.

Present embodiment adopts hot melting way to be connected with the PP-R pipeline, and is simple in structure, connects reliably, and can secretly bury with pipeline, effectively overcome metal valve and used the problem that exists.

More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
