Abstract
Stop valve for plastic pipeline 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; split sockets used for the insertion of the plastic pipeline are installed in the water inlet and the water outlet; the valve seat adopts a cylindrical valve seat; the valve core and the valve seat are in sliding fit; the valve core is connected with a valve rod which is connected with a handle; a sleeve is arranged on the valve seat; the handle is mounted at the upper end of the sleeve; external threads are formed on the sleeve; internal threads matched with the external threads are formed on the handle; when rotated, the handle can move up and down relatively to the sleeve; a valve cap is arranged between the sleeve and the valve seat; and the valve rod penetrates through the valve cap; and when in use, the handle is rotated by hand, up and down moving displacement can be caused by the rotation of handle, which drives the valve rod to move up and down, therefore, the valve core is driven to move up and down, which causes the water flowing through the valve body to stop or flow continuously.
Description
Technical field
The utility model relates to the plastic pipe valve technology field, the concrete ducted stop valve of a kind of PP-R of being used for that relates to.
Background technique
Stop valve has in pipe-line system widely to be used, and especially using scope is very extensive in common waterway pipe.But development along with society, common waterway pipe becomes plastic pipe by original metallic conduit, but stop valve originally is metal valve not yet, metal valve is installed in the plastic pipe, easily plastic pipe is burst, and the easy corrosion of metal valve is revealed or the valve damage and produce, and has very big defective so metal valve is used in plastic pipe.
The model utility content
Technical problem to be solved in the utility model is, overcomes problems of the prior art, and a kind of plastic pipe stop valve is provided.
In order to address the above problem the technical solution of the utility model is such:
The plastic pipe stop valve comprises the plastics valve body, is arranged on valve seat, the spool of valve inner, the valve body two ends have intake-outlet, it is characterized in that described intake-outlet is connected by hot melting way with plastic pipe, in intake-outlet, be provided with the amalgamation socket that is used for the plastic pipe insertion.
Described valve seat is the tubular valve seat, and spool and valve seat are slidingly matched mutually.
Described spool connects a valve rod, and valve rod connects one handle.
Described valve seat is provided with a sleeve, and described handle is arranged on the sleeve upper end, has outside thread on the sleeve, has the internal thread that matches with outside thread on the handle, and handle can move up and down by relative sleeve when handle rotated.
Be provided with valve gap between described sleeve and the valve seat, described valve rod passes valve gap.
During use, manually turn handle, handle can move up and down displacement because of rotation produces, and the valve rod that moves up and down and then drive of handle moves up and down, the spool that can drive simultaneously up and down of valve rod moves up and down, and spool moves and will make the valve body current of flowing through stop or continuing flowing.
Beneficial effect: stop valve structure described in the utility model is simple, and is easy to use, and rotation easily connects reliably, can not produce corrosion, the problem of effectively having avoided the metal stop valve to exist.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structural representation of plastic pipe stop valve 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
The plastic pipe stop valve is mainly used in the plastic duct system, and in the PP-R pipe-line system, the PP-R pipeline is mainly used in the conveying of resident living water, at the PP-R pipeline switching of stop valve with controlled water flow need be installed.
This stop valve has a valve body 1, and valve body 1 is made for the PP-R material, and the valve body two ends have intake-outlet 11, and intake-outlet 11 is used to connect PP-R pipeline 12.Make because valve body 1 all is the PP-R material, described intake-outlet 11 also all is the PP-R material, and intake-outlet 11 can be well suited for like this carries out hot melt with PP-R pipeline 12 and be connected.Be provided with the amalgamation socket 13 that is used for the insertion of PP-R pipeline in the intake-outlet 11, the internal diameter of amalgamation socket 13 is more than or equal to PP-R pipeline 12 external diameters, to be fit to the insertion of PP-R pipeline 12.After hot melt connects, stable mechanical property, sound construction, attachment security are reliable.
Please continue referring to Fig. 1, valve body 1 inside is provided with valve seat 2, and valve seat 2 is the tubular valve seat, and valve seat 2 is used to be communicated with intake-outlet 11.Valve seat 2 inside are provided with the spool 3 that is slidingly matched, and spool 3 connects valve rod 4, and valve rod 4 connects handle 5.When handle 5 rotates, can drive valve rod 4 and move up and down, and then drive spool 3 and move up and down, finish the switching of valve body.Also be provided with valve gap 6 on valve body 1, valve rod 4 passes valve gap 6 and valve rod 4 can slide in valve gap 6.In order to guarantee the sealability of valve inner, be provided with seal ring 7 between valve rod 4 and the valve gap 6, seal ring 7 is the double sealing circle, to reach the purpose of security seal.Valve body 1 top also is provided with sleeve 8 in addition, sleeve 8 is fixedlyed connected with valve body 1, sleeve 8 upper outside have outside thread, handle 5 inboards have internal thread, the internal thread of handle 5 matches with the outside thread of sleeve 8, when handle with sleeve 5, handle 5 can move up and down by relative sleeve 8, and then drives valve rod 4 motions.And 8 inside that are positioned at sleeve 8 of valve gap 6 relative sleeves.
During use, manually turn handle, handle can move up and down displacement because of rotation produces, and the valve rod that moves up and down and then drive of handle moves up and down, the spool that can drive simultaneously up and down of valve rod moves up and down, and spool moves and will make the valve body current of flowing through stop or continuing flowing.
Compared with prior art, the described PP-R stop valve structure of present embodiment is simple, easy to use, and rotation easily connects reliably, can not produce corrosion, the problem of effectively having avoided the metal stop valve to exist.
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.
