Abstract
The utility model provides a gas conveyer pipe, including the nonrust corrugated steel pipe of inlayer, still include to set up at the outer PVC coating layer of the nonrust corrugated steel pipe of inlayer, PVC coating layer inner wall is equipped with a set of saw type rack. The utility model discloses simple structure, reasonable in design, it is flexible good, flexible, pass through PVC pipe low in labor strength, satisfy water heater and cooking utensils and use flow demand. The external diameter is less than 17.5mm, can pass 12 nuts, can adopt single nut structure sealed with gas pipeline valve gate or articulate, connects safe and reliable.
Description
Technical field
This utility model relates to a kind of gas supply pipe, a kind of metal bellows being applicable between gas meter with valve before Gas appliance be connected, and belongs to gas pipeline connection area.
Background technology
At present, fine fitment the commercial house ensure that total quality and the delivery cycle of the commercial house because of real estate developer's normalized construction, avoid the potential safety hazard of house purchaser's follow-up finishing generation lack of standardization, decrease the waste of follow-up finishing material, the series of problems such as with high costs simultaneously.
The system of laying the most pre-buried commonly used pvc pipe that fine fitment the commercial house gas supply pipe arrives, later stage gas pipeline passes through the design of pvc pipe, and the conveying pipe stiffness of DN13 or DN15 conventional on market is big, it is difficult to pass through pvc pipe.
This just requires that the conveying pipe specification passing through pvc pipe disclosure satisfy that traffic demand when domestic gas-fired water heater or gas kitchen ranges normally use, and has enough flexibilities again, it is possible to fast pass through pre-buried pvc pipe.
Utility model content
The purpose of this utility model is, the problem existed for above-mentioned prior art, proposes a kind of flexible, and rigidity is little, it is possible to quickly pass through the conveying pipe of pre-buried pvc pipe.
In order to solve above technical problem, this utility model provides a kind of gas supply pipe, including internal layer corrugated stainless steel tubing, it is characterised in that: also including the PVC coating being arranged on internal layer corrugated stainless steel tubing outer layer, described PVC coating inwall is provided with one group of saw type tooth bar.
The technical scheme that this utility model limits further is:
Further, described saw type tooth bar has 30～35, and height is 0.25mm, and thickness is less than 0.75mm.
Further, the internal diameter of described internal layer corrugated stainless steel tubing is more than 12.5mm.
Further, the external diameter of described internal layer corrugated stainless steel tubing is less than 17.5mm, and the pitch of waves of ripple is less than 4mm.
The beneficial effects of the utility model: this utility model simple in construction, reasonable in design, flexible, flexible, pass through pvc pipe labor intensity low, meet water heater and kitchen range use traffic demand.External diameter is less than 17.5mm, it is possible to through 1/2 nut, it is possible to using single nut structure to be connected sealing with valve of gas pipeline or joint, attachment security is reliable.
Accompanying drawing explanation
Below in conjunction with embodiment, this utility model is described further:
Fig. 1 is the structural representation of this utility model device.
Detailed description of the invention
Embodiment
1
A kind of gas supply pipe that the present embodiment provides, as shown in Figure 1: include corrugated stainless steel tubing 1 and PVC coating 2.
Corrugated stainless steel tubing 1 is in continuous circular shape corrugated, it is possible to free bend.The internal diameter of corrugated stainless steel tubing is more than 12.5mm, and external diameter is less than 16mm, and the pitch of waves is less than 4.0mm, and rigidity is little, flexible.
PVC coating 2 anticorrosion, fire-retardant, antistatic, have aeration function, smooth outer surface easy to clean, and inner surface periphery is provided with 30 ~ 35 saw type tooth bars high for 0.25mm.
During in-site installation, can quickly intercept according to lay length and system of laying cutter, coordinate 1/2 nut, it is possible to quickly assemble and be connected sealing with the nipple of gas pipeline or valve.Job site, can use rope traction, two operator to coordinate, and people's traction, a people send the compounding practice mode of pipe, passes rapidly through pre-buried pvc pipe.
In addition to the implementation, this utility model can also have other embodiments.The technical scheme that all employing equivalents or equivalent transformation are formed, all falls within the protection domain of this utility model requirement.
