Description
Technical field
A kind of stainless steel flexible hose is the utility model is related to, specially a kind of Explosion proof joint of stainless steel flexible hose water inlet end.
Background technology
Stainless steel flexible hose is mainly used in interior conduit and the connection with tap or flowing water Valve.Existing stainless steel flexible hose its
Water inlet end is identical with the joint design of water side, and concrete structure is as shown in figure 1, main all by joint body 1 ', coupling nut 2 '
Formed with seal washer 3 ', joint body 1 ' therein is a bypass structure.
Being found through use for many years, easily there is Decrepitation Phenomena in itself in stainless steel flexible hose, but because of the water inlet end of existing flexible pipe 4 '
Joint does not have explosion-proof water stopping function, once explosion occur may result in that flowing water is more than, not only causes the waste of water, and can be because of water
Spilling and cause the damage of floor or furniture, very big hidden danger safe to use be present.
Utility model content
In view of the above-mentioned problems, the utility model devises a kind of Explosion proof joint of stainless steel flexible hose water inlet end, it can flow
The hydraulic pressure crossed closes water inlet end automatically when increased dramatically, and to avoid current when flexible pipe bursts more than, avoids causing irretrievable
Damage, have it is simple and practical the characteristics of.
To achieve the above object, the utility model uses following technical scheme：
A kind of Explosion proof joint of stainless steel flexible hose water inlet end, including joint body, it is characterised in that：The joint body
Endoporus is divided into the aperture runoff water section of the inner and the large aperture installation hole section of outer end, is sequentially set outward from interior in the installation hole section
Put back-moving spring, spring base and the capping with some water-guiding holes；The back-moving spring has pre compressed magnitude and by spring base top
Hold and a dynamic matching relationship is formed in capping endoporus bottom, will be pressed further by when the hydraulic pressure flowed through increased dramatically with flexible spring seat
Back-moving spring and make spring base head enter flowing water section oral area and realize closure sealing.
Further, above-mentioned spring base bottom outer wall is distributed with some support feets around circumferentially-spaced, adjacent supports pin
Gap forms pipelined channel.
Further, above-mentioned back-moving spring the inner is held in the bottom of installation hole section, and the outer end of back-moving spring is held in bullet
In each support feet of spring abutment.
Further, the head outer diameter of above-mentioned spring base is gradually reduced and forms a taper header structure.
Further, above-mentioned capping is made up of excircle boss and end, and the outer circular bosses and the installation hole section are tight
It is connected and its top holds and sets some water-guiding holes on the bottom of installation hole section, the end.
The utility model lead to joint body endoporus set installation hole section, and in hole section be installed setting by back-moving spring,
The blast resistance construction that spring base and capping are formed, the blast resistance construction can close water inlet termination automatically when the hydraulic pressure flowed through increased dramatically
Head, to avoid current when flexible pipe bursts more than, avoid causing irremediable damage, there is the characteristics of simple and practical.
Brief description of the drawings
Fig. 1, existing stainless steel steel flexible pipe water inlet end joint design sectional view；
Fig. 2, structure sectional view of the present utility model.
Embodiment
As shown in Fig. 2 a kind of Explosion proof joint of stainless steel flexible hose water inlet end, including joint body 1, the endoporus of joint body
It is divided into the aperture runoff water section 11 of the inner and the large aperture installation hole section 12 of outer end.
Back-moving spring 2, spring base 3 are sequentially set outward and with some water-guiding holes 41 from interior in the installation hole section 12
Capping 4.
The bottom outer wall of spring base 3 is distributed with some support feets 31, the gap of adjacent supports pin 31 around circumferentially-spaced
Form pipelined channel 32.The head outer diameter of the spring base 3 is gradually reduced and forms the structure of a conical head 33.
Described the inner of back-moving spring 2 is held in the bottom of installation hole section 12, and the outer end of back-moving spring 2 is held in spring base 3
Each support feet 31 on.Under original state, back-moving spring 2 has pre compressed magnitude and holds spring base 3 and covering 4 endoporus bottoms
And form a dynamic matching relationship.When the hydraulic pressure flowed through increased dramatically, current will be pressed further by back-moving spring 2 with flexible spring seat 3
And spring base conical head 33 is set to enter the oral area of flowing water section 11 and realize closure sealing.
The capping 4 is made up of excircle boss 4a and end 4b.Wherein outer circular bosses 4a and the installation hole section 12 are tight
It is connected and its top holds and sets some water-guiding holes 41 on the bottom of installation hole section 12, the end 4b.
The utility model leads to sets installation hole section 12 in the endoporus of joint body 1, and is set in hole section 12 is installed and reset bullet
Spring 2, spring base 3 and capping 4 form blast resistance construction.
In normal water outlet, because flowing through the water of joint than shallower, thrust very little that spring base 3 is subject to, it is difficult to further
Compression reseting spring 2, now flowing water is through the pipelined channel 32 between the water-guiding hole 41 in capping 4, spring base adjacent supports pin 31
The inner aperture runoff water section 11 of the endoporus of joint body 1 is flowed to afterwards, keeps normal water outlet.
And the Decrepitation Phenomena of flexible pipe 5 once occurs, the current for now flowing through joint are drastically accelerated, and hydraulic pressure steeply rises, now
The current of high speed block impact spring seat 3, the further compression reseting spring 2 of push the spring seat 3 until the conical head 33 of spring base
Enter in the flowing water section 11 of the endoporus of joint body 1 and realize closure sealing, to realize explosion-proof water stopping function.
To sum up, the Explosion proof joint of the stainless steel flexible hose water inlet end of the utility model design, it can be in the hydraulic pressure flowed through drastically
Automatically water inlet end is closed during increase, to avoid current when flexible pipe bursts more than, can avoid causing irremediable loss, have
The characteristics of simple and practical.
It is described above, only it is better embodiment of the present utility model, not the utility model is made any formal
Limitation, it is every to any simple modification made for any of the above embodiments, equivalent variations or to be repaiied according to technical principle of the present utility model
Decorations, in the range of still falling within technical solutions of the utility model.
