Abstract
The utility model relates to a stop valve for a plastic water pipe. The valve rod is spirally connected with a valve core positioned in the valve body through the outer thread of the valve rod, a valve cap is suited on the valve core in a gapped way and connected with the valve body through thread or a flange, and a seal ring is arranged between the upper flange of the valve cap and the valve rod; an inlet pipe and an outlet pipe are arranged on the valve body, the inlet pipe is arranged coaxially with the valve rod, and the outlet pipe and the valve rod are arranged vertically or in an acute angled way. The stop valve has the advantages that the structure is simple, the disassembly is convenient, the connection between the plastic water pipe and a threaded water pipe is convenient, and the problem of installing a valve at the bend of a pipe is solved.
Description
Technical field
The utility model relates to valve, especially for the matching used low pressure water valve of plastic water pipe.
Background technique
Existing water valve, especially from the beginning water valve mainly is made up of valve body and spool, valve body is three-way pipe always, valve core axis is vertical with valve axis, be that intake pipe and outlet pipe all belong to this class stretched formula stop valve by same axis or substantially by the setting that parallels to the axis as Chinese patent literature patent No. 200410021962.1,200410022129.9,200410022291.0,200410022471.9 etc. on the valve body.And existing piping erection use in the time have need be in the situation of pipeline turning mounted valve, above-mentioned stretched formula valve can not be installed and used in the pipeline corner, can not satisfy this generic request.
The model utility content
The purpose of this utility model provide a kind of be applicable at the pipeline turning install, simple in structure, plastic water pipe stop valve that spool is convenient to dismounting, maintenance.
This novel purpose is achieved in that a kind of plastic water pipe stop valve, comprise valve body, valve rod is connected with the spool spiral that is positioned at described valve body through its external sealing plug, valve gap be enclosed within a gap on the spool and with valve body through being threaded or being connected through flange, be provided with seal ring between valve gap upper flange and the valve rod; Inlet tube and outer pipe are arranged on the described valve body, and inlet tube and valve rod are coaxially set, and outer pipe is vertical with valve rod axis or be the acute angle setting.
The applicant had once proposed the patent application of " inclined stop valve " (application number 200820064945.X) in 2008, the application is based on the improvement of above-mentioned " inclined stop valve " and replenishes, so that use matches with existing plastic water pipe (especially tap water supply pipe network).
Compared with prior art, this novel beneficial effect is:
1, simple in structure, be convenient to dismounting assembling, convenient for maintaining
Valve gap is connected with valve body silk mouth, and valve rod is connected with spool silk mouth, and therefore, valve gap, valve rod, spool can take out from valve body easily, is convenient to maintenance, changes component, is convenient to the clearing valve intracoelomic cavity; Simultaneously, handle is connected on the valve rod through screw threads, the same easy disassembly of handle.
2, specific aim has solved the problem at pipe bending place mounted valve
Intake pipe is vertical with outlet pipe or be certain inclination angle (20 degree～60 degree) on the valve body, can make series product, to solve the problem of installing on differently curved degree pipeline.Simultaneously, intake pipe and/or outlet pipe are provided with threaded insert, can be easily and being connected of plastic water pipe and band silk water pipe.
If when not doing the valve use on this pipeline location, can easily valve gap, valve rod, spool be removed from valve body, this novel valve body promptly can be used as a three-way pipe (right angle trigonometry or skew T) and uses.
3, easy to install, but material saving also, time and labour saving opens and closes lightly, and and long service life is closed effective.
4, can be used as the stop valve with certain antitheft usefulness function uses
If the valve rod top is made a tri-prism (and without handle), promptly need use special tool ability Open valve.

Embodiment
Fig. 1 illustrates, and valve rod 2 is connected with spool 3 spirals that are positioned at described valve body 5 through its external sealing plug, valve gap 4 be enclosed within a gap on the spool 3 and with valve body 5 through being threaded or being connected through flange, be provided with seal ring 7 between valve gap 4 upper flange and the valve rod; Inlet tube 5a and outer pipe 5b are arranged on the valve body 5, and inlet tube 5a and valve rod 2 are coaxially set, and outer pipe is vertical with valve rod axis or be acute angle setting (referring to Fig. 4).There is handwheel 1 at valve rod 2 tops through screw.Valve body 5 is the plastics valve body, and described valve body 5 fixing threaded insert 6 on it is connected with valve gap 4 spirals.The outer pipe 5b inwall of valve body 5 is fixed with threaded insert 6a.The inlet tube 5a inwall of valve body 5 is fixed with threaded insert 6b, and perhaps, inlet tube and outer pipe inwall all are provided with threaded insert.Spool 3 bottoms are fixed with seal rubber pad 3a.
Referring to Fig. 5, valve rod 2 tops are provided with a tri-prism 2a.Have draw-in groove between valve rod 2 tops and the valve gap 4, be provided with collar 8 in the draw-in groove with a gap.
This novel and former patent inclined stop valve is the same can to design production 20～200 or more bigbore plastic cement stop valve or metal stop valve.The valve body of bigbore slightly plastic cement stop valve (as more than 75 or 75) or bigbore slightly metal right angle or inclined stop valve is connected with valve gap and can connects by the silk mouth, and otherwise connects, and connects as flange.
