Abstract
The invention discloses a full-copper water touching composite plastic stop valve. The stop valve comprises a valve body, external connecting straight pipes, PPR pipe layers, red copper pipe layers and copper connecting rings. The valve body is connected with the external connecting straight pipes through the copper connecting rings. The external connecting straight pipes are composed of the PPR pipe layers and the red copper pipe layers. Each red copper pipe layer is located inside the corresponding PPR pipe layer. Airtightness of the stop valve is good. A full-copper water touching effect can be achieved through design of the copper connecting rings. Copper has the advantages of being capable of achieving sterilization and bacteriostasis, long in service life, not prone to ageing, high in safety and stability, healthy and environmentally friendly by itself.
Description
Technical field
The present invention relates to stop valve field, a kind of full copper touches water and moulds stop valve again.
Background technology
Stop valve, also known as pipe valve valve, belongs to forced seal formula valve, so when valve closing, it is necessary to valve
Lobe applies pressure, does not leaks with forced seal face.When medium is by entrance valve below flap, operating physical force institute
Need the resistance that overcomes, be the frictional force of valve rod and filler with by thrust produced by the pressure of medium, close valve
The power of the force rate valve opening door of door is big, so the diameter of valve rod wants big, the fault of valve rod bending otherwise can occur.
It is divided into three kinds: Flange joint, screwed connection, be welded to connect by connected mode.Occur from self-packing valve
After, the medium of stop valve flows to just change by entering valve pocket above flap, at this moment under pressure medium effect, closes
The power of valve is little, and the power of valve opening door is big, and the diameter of valve rod can correspondingly reduce.Meanwhile, make at medium
Under with, the valve of this form is the tightest.China's valve " three changes are given " once specified, the flow direction of stop valve,
Use from top to bottom without exception.When stop valve is opened, the Lift of flap, for the 25%～30% of nominal diameter
Time. flow has reached maximum, represents that valve has reached fully open position.So the fully open position of stop valve, Ying Youfa
The stroke of lobe determines.Family expenses feed pipe uses PPR stop valve more universal the most on the market, but PPR
Stop valve uses for a long time and easily nourishes bacterium, and PPR is soluble in water, and high temperature deformation is aging soon, and sealing is poor.
Summary of the invention
Technical problem solved by the invention is that providing a kind of full copper to touch water moulds stop valve again, above-mentioned to solve
Problem.
Technical problem solved by the invention realizes by the following technical solutions:
A kind of full copper touches water and moulds stop valve again, including valve body, external straight tube, PPR pipe layer, red copper tube layer, copper
T-Ring, described valve body is connected with external straight tube by copper T-Ring, and described external straight tube is by PPR pipe layer and red copper
Tube layer forms, and described red copper tube layer is positioned at inside PPR pipe layer.
As preferably, described stop valve uses symmetrical expression distributed architecture.
As preferably, the technological principle of described stop valve is that valve body internal layer uses red copper tube layer, and outer layer uses PPR
Tube layer, allows red copper tube layer and PPR pipe layer hot melt extrude glued one and helps copper and touch water and mould stop valve again.
As preferably, described copper T-Ring and stop valve are not integral structures, and the valve body left and right sides is the most external
Straight tube might as well or other pipe fitting must lay copper T-Ring and can be only achieved real full copper and touch water effect.
Good airproof performance of the present invention, the design of copper T-Ring reaches full copper and touches water effect, and this province of copper has sterilization and presses down
Bacterium, service life is long, is difficult to aging, and safe and stable property is high, health environment-friendly.

Fig. 2 is the structural representation of valve body of the present invention；
Fig. 3 is the right view of the present invention；
Fig. 4 is the left view of the present invention.
Detailed description of the invention
In order to make realizing technological means, creation characteristic, reaching purpose and be easy to understand with effect of the present invention,
Below in conjunction with being specifically illustrating, the present invention is expanded on further.
As Figure 1-4, a kind of full copper touches water and moulds stop valve again, including valve body 1, external straight tube 2, PPR
Tube layer 3, red copper tube layer 4, copper T-Ring 5, described valve body 1 is connected with external straight tube 2 by copper T-Ring 5,
Described external straight tube 2 is made up of PPR pipe layer 3 and red copper tube layer 4, and described red copper tube layer 4 is positioned at PPR pipe
Layer 3 is internal.
As preferably, described stop valve uses symmetrical expression distributed architecture.
As preferably, the technological principle of described stop valve is that valve body 1 internal layer uses red copper tube layer 4, and outer layer uses
PPR pipe layer 3, allows red copper tube layer 4 and PPR pipe layer 3 hot melt extrude glued one and helps copper and touch water and mould again and cut
Only valve.
As preferably, described copper T-Ring 5 is not integral structure with stop valve, and valve body 1 left and right sides no matter
External straight tube 2 might as well or other pipe fitting must lay copper T-Ring 5 and can be only achieved real full copper and touch water effect.
Good airproof performance of the present invention, the design of copper T-Ring reaches full copper and touches water effect, and this province of copper has sterilization and presses down
Bacterium, service life is long, is difficult to aging, and safe and stable property is high, health environment-friendly.
The general principle of the present invention and principal character and advantages of the present invention have more than been shown and described.The industry
Skilled person will appreciate that, the present invention is not restricted to the described embodiments, in above-described embodiment and specification
The principle that the present invention is simply described described, without departing from the spirit and scope of the present invention, the present invention
Also having various changes and modifications, these changes and improvements both fall within scope of the claimed invention.This
The claimed scope of invention is defined by appending claims and equivalent thereof.
