Abstract
The utility model discloses a stainless steel corrugated hose for connection of a gas appliance, which is characterized in that the stainless steel corrugated hose have a clingy wave shape, and is 2.9 to 3.2 mm in wave depth and 0.8 to 1.2 mm in wave pitch. Preferably, the selected stainless steel corrugated hose is 3 mm in wave depth and 1 mm in wave pitch. By changing the structural size of the stainless steel corrugated hose, the fatigue resistance and quality the stainless steel corrugated hose are greatly improved, and the service life of the stainless steel corrugated hose is prolonged, so that the conventional stainless steel corrugated hose is more suitable for a table-type cooker.
Description
Technical field
The utility model relates to combustion gas joint, particularly relates to stainless steel ripple flexible pipe.
Background technique
Tradition gas utensil connects employing rubber pipe conventionally, because rubber pipe exists, easily come off, easily aging, non-refractory, easily by sharp objects, easily punctured body, the problem such as inflammable, thereby bring out a series of gas safe accident that produces, bring a series of serious consequence to the country and people's safety.For this reason, stainless steel ripple flexible pipe arises at the historic moment, and body is selected SUS304 stainless steel, covers soft PVC sheath outward.And existing bellows ripple's depth is only 1.6 millimeters, the pitch of waves is 4 millimeters, side view is a little like triangle, obtaining its 90 degree number of twists is only 280 times conventionally, 60 degree number of bends are 3500 left and right, and suppleness is poor, causes it to be only applicable to not need roving Embedded kitchen range, inapplicable to the roving table type kitchen range of needs, if used by force, on table type kitchen range, easily cause gas connection pipe road to occur gas leakage hidden danger.
Model utility content
The technical problems to be solved in the utility model is the present situation for prior art, provides a kind of gas appliance with superior bending properties that is applicable to table type kitchen range to connect with stainless steel ripple flexible pipe.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of gas appliance connects with stainless steel ripple flexible pipe, it is characterized in that: stainless steel ripple flexible pipe is for being close to waveform, the depth of convolution of described stainless steel ripple flexible pipe is at 2.9～3.2 millimeters, and the pitch of waves is at 0.8～1.2 millimeter.What is called is close to adjacent two ripples that waveform is characterized in that corrugated flexible hose and is contacted, very close to each other between adjacent peaks and crest.
The depth of convolution of the stainless steel ripple flexible pipe that the utility model is preferentially selected is 3 millimeters, and the pitch of waves is 1 millimeter.
As improvement, also comprise be wrapped in described stainless steel ripple flexible pipe side face clad, be enclosed within the joint steel bushing of the clad of described corrugated flexible hose connecting end, on described joint steel bushing, have and detect hole, described clad internal surface has the gas guide groove of some vertically.By lay leakage detector near detecting hole, make like this corrugated flexible hose inside have any gas leakage all can flow to and detect hole along gas guide groove, thereby make leakage detector send alarm signal, combustion gas is used safer.
Compared with prior art, adopt the advantage of technical solutions of the utility model to be: the depth of convolution and the pitch of waves size by employing, being close to waveform and changing stainless steel ripple flexible pipe, significantly improved the bending properties of stainless steel ripple flexible pipe, make it be applicable to need roving table type kitchen range working environment, reduced stainless steel ripple flexible pipe and caused the probability of gas leakage because of flexural fatigue.
Accompanying drawing explanation
Fig. 1 is that in the utility model embodiment, gas appliance connects the schematic diagram with stainless steel ripple flexible pipe;
Fig. 2 is the sectional view at A place in Fig. 1;
Fig. 3 is the structural representation of stainless steel ripple flexible pipe in the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figures 1 to 3, gas appliance in this enforcement connects by stainless steel ripple hose package to be drawn together stainless steel ripple flexible pipe 3, is wrapped in the joint steel bushing 1 that this stainless steel ripple flexible pipe 3 is managed the clad 2 of side faces, is enclosed within the clad 2 of these stainless steel ripple flexible pipe 3 connecting ends 31, on joint steel bushing 1, have and detect hole 11, clad 2 internal surfaces that adopt have the gas guide groove 21 of some vertically, wherein stainless steel ripple flexible pipe 3 is for being close to waveform, the depth of convolution D of stainless steel ripple flexible pipe 3 is at 2.9～3.2 millimeters, and pitch of waves E is at 0.8～1.2 millimeter.What is called is close to adjacent two ripples that waveform is characterized in that corrugated flexible hose 3 and is contacted, very close to each other between adjacent peaks and crest.
Wherein, the depth of convolution of the stainless steel ripple flexible pipe of preferentially selecting is 3 millimeters, and the pitch of waves is 1 millimeter.
The relative prior art of the present embodiment, under equal conditions, 90 degree number of twists can reach 8000 times, and 60 degree bendings can reach 30000 times by number of times, and suppleness is only 5 newton.Wherein suppleness refers to the needed power of stainless steel ripple hose bending 60 degree.The fatigue resistance that has so significantly improved stainless steel ripple flexible pipe, has improved its quality and working life, thereby has reduced the risk of gas leakage
In addition, for the purpose of further safety, near detecting hole 11, lay leakage detector, make corrugated flexible hose 3 inside have any gas leakage all can flow to and detect hole 11 along gas guide groove 21, thereby make leakage detector send alarm signal, thereby use gas safer.
