Abstract
The utility model discloses a kind of full copper to touch water and mould stop valve again, comprise 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, described external straight tube is made up of PPR pipe layer and red copper tube layer, and it is inner that described red copper tube layer is positioned at PPR pipe layer.The utility model good airproof performance, the design of copper T-Ring reaches full copper and touches water effect, and this province of copper has bactericidal, long service life, not easily aging, and safety, stability are high, health environment-friendly.
Description
Technical field
The utility model relates to stop valve field, is specially a kind of full copper and touches water and mould stop valve again.
Background technique
Stop valve, also known as pipe valve valve, belongs to forced seal formula valve, so when valve closing, must apply pressure, do not leak with forced seal face to flap.When medium is by when entering valve below flap, the resistance overcome required for steering force, be the frictional force of valve rod and filler and the thrust produced by the pressure of medium, the power of the force rate valve opening door of closing valve is large, so the diameter of valve rod wants large, otherwise the fault of valve rod bending can be there is.Three kinds are divided into: Flange joint, screwed connection, to be welded to connect by Placement.After occurring from self-packing valve, the MEDIA FLOW of stop valve enters valve pocket to just changing by above flap, and at this moment under pressure medium effect, the power of closing valve is little, and the power of valve opening door is large, and the diameter of valve rod can correspondingly reduce.Meanwhile, under medium effect, the valve of this form is also tighter.China's valve " three changes are given " once specified, the flow direction of stop valve, adopted from top to bottom without exception.Stop valve open time, the Lift of flap, for nominal diameter 25% ~ 30% time. flow has reached maximum, represent valve reach fully open position.So the fully open position of stop valve, should be decided by the stroke of flap.At present family expenses supply pipe uses PPR stop valve comparatively general 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 soon aging, and sealing is poor.
Model utility content
The technical problem that the utility model solves is that providing a kind of full copper to touch water moulds stop valve, again to solve the problem.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of full copper touches water and moulds stop valve again, comprise 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 made up of PPR pipe layer and red copper tube layer, and it is inner that described red copper tube layer is positioned at PPR pipe layer.
As preferably, described stop valve adopts symmetric type distributed architecture.
As preferably, the technological principle of described stop valve is that valve body internal layer adopts red copper tube layer, outerly adopts PPR pipe layer, allows red copper tube layer and PPR pipe layer hot melt extrude to glue together integrally and helps copper and touch water and mould stop valve again.
As preferably, described copper T-Ring and stop valve are not integral structures, full the valve body left and right sides no matter external straight tube might as well or other pipe fitting must lay copper T-Ring and just can reach real copper and touch water effect.
The utility model good airproof performance, the design of copper T-Ring reaches full copper and touches water effect, and this province of copper has bactericidal, long service life, not easily aging, and safety, stability are high, health environment-friendly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model valve body;
Fig. 3 is right elevation of the present utility model;
Fig. 4 is left view of the present utility model.
Embodiment
In order to make actualizing technology means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model further.
As Figure 1-4, a kind of full copper touches water and moulds stop valve again, comprise valve body 1, external straight tube 2, PPR pipe 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 it is inner that described red copper tube layer 4 is positioned at PPR pipe layer 3.
As preferably, described stop valve adopts symmetric type distributed architecture.
As preferably, the technological principle of described stop valve is that valve body 1 internal layer adopts red copper tube layer 4, outerly adopts PPR pipe layer 3, allows red copper tube layer 4 and PPR pipe layer 3 hot melt extrude glue together integrally and helps copper and touch water and mould stop valve again.
As preferably, described copper T-Ring 5 is not integral structure with stop valve, Quan the no matter external straight tube 2 in valve body 1 left and right sides might as well or other pipe fitting must lay copper T-Ring 5 and just can reach real copper and touch water effect.
The utility model good airproof performance, the design of copper T-Ring reaches full copper and touches water effect, and this province of copper has bactericidal, long service life, not easily aging, and safety, stability are high, health environment-friendly.
More than show and describe basic principle of the present utility model and 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; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
