Abstract
The utility model discloses a telescopic membrane module, including connecting the base plate and setting up the seal membrane on connecting the base plate, the linking group slab is the annular piece, annular piece middle part is equipped with the seal membrane, the seal membrane includes the lateral wall of tube -shape and the sealing membrane who sets up in lateral wall one end, and outside extension of lateral wall other end outer fringe is equipped with the connecting portion of being connected with the annular piece, the annular piece is equipped with two, connecting portion set up in the middle of two annular pieces, connecting portion bond with the annular piece is sealed, sealing membrane is the plastic film, the lateral wall is formed by plastic film and the concatenation of elastic emulsion membrane. Through setting up the seal membrane as that can to follow the axial protruding or to the sunken structure in inside to the outside, can be so that the membrane module volume be variable for the inside atmospheric pressure of buffering changes, guarantees sealed effect, with the lateral wall set up into plastic film and the concatenation of elastic emulsion membrane can be so that the elastic space of seal membrane one point, pressurize carrying capacity.
Description
Technical field
The utility model relates to telescopic membrane module.
Background technique
As everyone knows, existing engineering pipe, pipe fitting in particular for iron skill is steel pipe, in the maintenance process in later stage, need that regular to carry out japanning to body antirust, body is hollow tubular, after first japanning, in maintenance process, inwall japanning is carried out very not easily to already installed body, but only to coated outside, inwall is easy to get rusty under comparatively moist or corrosion-prone environment, from internal damage, body end is arranged sealing film and inboard wall of tube body isolation can be played corrosion-resistant effect, but the gas in body can expand or shrink due to the change of external temperature, the sealing film of body end can damage by gas pressure, it is made to lose the function of sealing.Prior art is badly in need of a kind of telescopic membrane module that can stretch.
Summary of the invention
The purpose of this utility model is to overcome the defect existed in prior art, provides a kind of telescopic membrane module that can stretch.
For achieving the above object, the technical solution of the utility model there is provided a kind of telescopic membrane module, comprise connection substrate and be arranged on the sealing film on connection substrate, described connection substrate sheet is ring segment, sealing film is provided with in the middle part of described ring segment, described sealing film comprises the sidewall of tubular and be arranged on the sealed membrane of sidewall one end, and sidewall the other end outer rim stretches out the joint being provided with and being connected with ring segment; Described ring segment is provided with two panels, and described joint is arranged in the middle of two panels ring segment, and described joint seals bonding with ring segment; Described sealed membrane is plastic film, and described sidewall is spliced by plastic film and elastic emulsion film.By be set to by sealing film can the protruding or structure that internally caves in laterally vertically, membrane module variable volume can be made, for cushioning air pressure inside change, ensure sealing effect, sidewall is set to plastic film and elastic emulsion film splicing sealing film can be made to have the elastic space of a bit, improve pressure tolerance.
As preferably, described plastic film and elastic emulsion film are spaced annular canister film, are welded between described plastic film with elastic emulsion film by ultrasonic sealing.Such design is the one optimization to scheme.
As preferably, described joint stretches out ring segment outer rim, and described joint outer rim is provided with T-shaped inserted part, and described T-shaped inserted part coordinates with ring segment outer rim.Such design prevents joint from skidding off from ring segment.
As preferably, described sealed membrane is rounded, and described circular sealed membrane is provided with the annular fold set gradually from outside to inside.Such design makes sealed membrane shape variable, increases variable-volume.
Advantage of the present utility model and beneficial effect are: by be set to by sealing film can the protruding or structure that internally caves in laterally vertically, membrane module variable volume can be made, for cushioning air pressure inside change, ensure sealing effect, sidewall is set to plastic film and elastic emulsion film splicing sealing film can be made to have the elastic space of a bit, improve pressure tolerance.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is annular pleated structure schematic diagram.
In figure: 1, connection substrate; 2, sidewall; 3, joint; 4, sealed membrane; 5, T-shaped inserted part; 6, plastic film; 7, elastic emulsion film; 8, annular fold.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As Figure 1-Figure 2, a kind of telescopic membrane module, the sealing film comprising connection substrate 1 and be arranged on connection substrate 1, described connection substrate 1 is ring segment, sealing film is provided with in the middle part of described ring segment, described sealing film comprises the sidewall 2 of tubular and is arranged on the sealed membrane 4 of sidewall 2 one end, and sidewall 2 the other end outer rim stretches out the joint 3 being provided with and being connected with ring segment; Described ring segment is provided with two panels, and described joint 3 is arranged in the middle of two panels ring segment, and described joint 3 seals bonding with ring segment; Described sealed membrane 4 is plastic film 6, and described sidewall 2 is spliced by plastic film 6 and elastic emulsion film 7.
Described plastic film 6 is spaced annular canister film with elastic emulsion film 7, and described plastic film 6 is welded by ultrasonic sealing with between elastic emulsion film 7.Plastic film 6 and elastic emulsion film 7 are set to annular tubular, are convenient to process and connection between the two.
Described joint 3 stretches out ring segment outer rim, and described joint 3 outer rim is provided with T-shaped inserted part 5, and described T-shaped inserted part 5 coordinates with ring segment outer rim.
Described sealed membrane 4 is rounded, and described circular sealed membrane 4 is provided with the annular fold 8 set gradually from outside to inside.When pressure change, annular fold 8 is unfolded or shrinks, and regulates the gas volume in body.
In use, connection substrate 1 and body end part seal are arranged, under the promotion when the air pressure in body rises at air, sidewall 2 and sealed membrane 4 are protruding outside body, turn up as pocket, and body inner air pressure reduces, and reaches balance with the external world; When air pressure in body declines under the promotion of air, sidewall 2 and sealed membrane 4 cave inward, and body inner air pressure reduces, and reaches balance with the external world; Elastic emulsion film 7 has certain elasticity and stretchability, can expand according to air pressure size, stops regulating, can play buffer protection function like this when pressure changes greatly after reaching inside and outside air pressure balance.When pressure is larger, joint 3 easily departs from ring segment, so need to arrange T-shaped inserted part 5, to carry out reinforcement fixing.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing from the front lower of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
