Abstract
The utility model discloses concave alloy expansion joint for a kind of polycrystalline silicon device, it is characterized in that it includes bellows (1), the two ends of described bellows (1) are connected with two shell rings (2) respectively, and the inner side of shell ring (2) is partial in described bellows (1) position.The utility model can dwindle the boundary dimension of product greatly, meets on-the-spot installation requirements, for product conduit, arranges and saves space.Product bellows and structural member material are Langaloy material, high pressure resistant, high temperature, the equal comparative superiority of corrosivity, the design of concave makes product tolerate to such an extent that live the frequent high temperature erosion-corrosion of pipeline medium, makes the product can long-term safe operation in extreme working environment.
Description
Technical field
The utility model relates to a kind of polysilicon industry device expansion joint.
Background technique
In recent years, along with the active response of national policy, photovoltaic industry is swift and violent in Chinese growth momentum.Polysilicon is a kind of form of elemental silicon, is the core parts of whole photovoltaic industry.Because photovoltaic industry at home belongs to novel energy industry, domestic corresponding auxiliary facility cannot be caught up with the developing steps of industry.Especially polycrystalline silicon device expansion joint, all need be from external buying, and existing expansion joint is bellows outer convex type, and boundary dimension is larger, cannot meet the demand of the sector.
Summary of the invention
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and long concave alloy expansion joint for polycrystalline silicon device of a kind of safe operation cycle is provided.
The technical solution adopted in the utility model is as follows:
A concave alloy expansion joint for polycrystalline silicon device, is characterized in that it includes bellows, and the two ends of described bellows are connected with two shell rings respectively, and the inner side of shell ring is partial in described bellows position.
Described shell ring one end is connected with bellows, and the other end is connected with regulating ring.
The outside of described bellows is provided with transportation fixed block, and the two ends of this fixed block are connected with described two shell rings respectively.
Described bellows, shell ring and regulating ring all adopt Langaloy material to make.
The beneficial effects of the utility model have:
The boundary dimension that can dwindle greatly product, meets on-the-spot installation requirements, for product conduit, arranges and saves space.Product bellows and structural member material are Langaloy material, high pressure resistant, high temperature, the equal comparative superiority of corrosivity, the design of concave makes product tolerate to such an extent that live the frequent high temperature erosion-corrosion of pipeline medium, makes the product can long-term safe operation in extreme working environment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, it includes bellows 1 the utility model, and the two ends of bellows 1 are connected with two shell rings 2 respectively, and the inner side of shell ring 2 is partial in bellows 1 position, is indent form.Above-mentioned two shell ring 2 one end are connected with bellows 1, and the other end is connected with regulating ring 3,4 respectively.In the outside of regulating ring 4, be provided with insertion pipe 5,6.The outside of bellows 1 is provided with transportation fixed block 7, and the two ends of this fixed block are connected with above-mentioned two shell rings 2 respectively.Bellows 1, shell ring 2 and regulating ring all adopt Langaloy material to make, and corrosion-resistant, high temperature, high-temperature behavior are superior.Between bellows 1 longitudinal seam and bellows 1 and shell ring 2, adopt argon arc welding welding, other structural member can adopt manual electric arc welding.
The actual compensation ability (approximately having more 1 ripple) that surpasses 8 ripples of compensation ability of the utility model corrugated pipe products.When bearing capacity calculates, adopted according to the mode of outside diameter of bel, adjust comparatively safe, and the unstability wave number of actual motion is calculated by many ripples, safety reliability is further strengthened, product bellows and structural member material are Langaloy material, and product wave number is more, the expansion of bellows is longer, so welding difficulty is higher, bellows 1 adopts the mode of swollen type Jia Pingbo cutting, this molding mode scrappage is higher, moulding difficulty is higher, but the negative and positive ripple of bellows is more full, and the error of radius R and design size is less.
The undeclared part relating in the utility model is same as the prior art.
