Abstract
The utility model discloses a reinforced liner of a corrugated pipe. The reinforced liner of the corrugated pipe comprises a corrugated pipe and end sockets, wherein the end sockets are in seal connection with the two ends of the corrugated pipe. An improvement of the reinforced liner of the corrugated pipe lies in that more than three rib plates are fixedly connected to the circumference of the internal wall of the corrugated pipe and are arranged in parallel along the direction of the central axis of the corrugated pipe. According to the reinforced liner of the corrugated pipe, the rib plates are fixedly connected to the circumference of the internal wall of the corrugated pipe, therefore, the rigidity of the liner of the corrugated pipe is obviously improved, the corrugated pipe is prevented from expanding and contracting along with temperature variation, the normal use of the liner of the corrugated pipe is ensured, and the service life of the liner of the corrugated pipe is prolonged.
Description
Technical field
The utility model relates to a kind of bellows inner-tube structure, and more particularly, the utility model relates to a kind of bellows inner-tube structure that in water heater, uses.
Background technology
The bellows inner bag that uses in the water heater is used for the heat exchange of water heater, comprises bellows, end socket, and end socket is sealedly connected on the bellows two ends, and bellows adopts the bellows of thin-wall metal compression moulding commonly used.Though the bellows inner bag of this structure is made easily, because the bellows wall thickness is thinner, whole bellows inner bag rigidity is relatively poor; The bellows inner bag is in heat transfer process; Bellows is flexible because of variations in temperature produces, and influences the normal use of bellows inner bag, and possibly cause the inefficacy of bellows inner bag.
The utility model content
The purpose of the utility model is the deficiency to prior art, provides a kind of and can significantly improve bellows inner bag rigidity, avoids bellows flexible because of variations in temperature produces, and guarantees the normal reinforced bellows inner bag that uses of bellows inner bag.
The utility model is realized technical goal through following technical proposals.
Reinforced bellows inner bag comprises bellows, end socket; Said end socket is sealedly connected on the bellows two ends; Its improvements are: on bellows inwall circumference, be fixedly connected the floor more than 3; Said floor laterally arranges by the bellows core axis direction.
A kind of further technical scheme of the utility model is: said floor axial length is than the short 10～15mm of bellows.
The another kind of further technical scheme of the utility model is: said floor is evenly arranged on the bellows inwall circumference.
The utility model compared with prior art; Has following good effect: on bellows inwall circumference, be fixedly connected floor, significantly improve bellows inner bag rigidity, avoid bellows flexible because of variations in temperature produces; Guarantee that the bellows inner bag normally uses, and has prolonged the service life of bellows inner bag.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Below according to accompanying drawing and combine embodiment that the utility model is described further.
Reinforced bellows inner bag shown in the drawings comprises bellows 2, end socket 1; End socket 1 is sealedly connected on bellows 2 two ends; On bellows 2 inwall circumference, evenly be fixedly connected 66 floors 3; Floor 3 laterally arranges by bellows 2 central axial direction; In the present embodiment, floor 3 axial lengths are than bellows 2 short 10mm.
On bellows 2 inwall circumference, be fixedly connected floor 3, significantly improve bellows inner bag rigidity, avoid bellows 2 flexible, guarantee that the bellows inner bag normally uses, and has prolonged the service life of bellows inner bag because of variations in temperature produces.
Claims (3)
1. a reinforced bellows inner bag comprises bellows (2), end socket (1); Said end socket (1) is sealedly connected on bellows (2) two ends; It is characterized in that: on bellows (2) inwall circumference, be fixedly connected the floor (3) more than 3; Said floor (3) laterally arranges by bellows (2) central axial direction.
2. reinforced bellows inner bag according to claim 1 is characterized in that: said floor (3) axial length is than the short 10～15mm of bellows (2).
