Detailed description of the invention

Below in conjunction with specific embodiment, this utility model is described in further detail.

Embodiment 1

As shown in figures 1 and 3, a kind of antistatic Explosion-proof host, pipeline 1 and the joint 2 being located at pipeline 1 two ends including hollow, pipeline 1 includes inner spring 11, the anti-corrosion layer 12 being wrapped in outside inner spring 11, the pressurize layer 13 being wrapped in outside anti-corrosion layer 12 and the wearing layer 14 being wrapped in outside pressurize layer 13 and the outer spring 15 being located at outside wearing layer 14, and joint 2 turns on inner spring 11 and outer spring 15. Inner spring 11 and outer spring 12 all have elasticity and lighter weight, therefore the weight of whole pipeline can be reduced, pipeline is made easily to bend, and because of the winding arrangement that spring itself has, can can provide to intermediate layer when opposite exterior lateral sides malleation or negative pressure inside pipeline 1 and effectively support, it is prevented that pipeline 1 deformation is split. Inner spring 11 can, by outside the timely delivery line of electrostatic of fluid motion generation, be directed on the equipment such as reactor by joint 2 as conductor, finally leads toward the earth, has thus ensured the safety in using.

Inner spring 11 and outer spring 15 adopt 304 rustless steels to make. This resistivity of material, at 2 ��/below m, therefore can make electrostatic quickly lead away, and density of material is little, good processability, corrosion-resistant, high temperature resistant reach 800 DEG C, be therefore adapted to the use occasion that some conditions are harsh, extend flexible pipe service life.

Anti-corrosion layer 12 is formed by teflin tape is wrapped. Anti-corrosion layer 12 has completely cut off the material of solvent and pressurize layer 13, it is prevented that pressurize layer 13 is corroded. Politef is high temperature resistant, non-conductive, has good anti acid alkali performance, is practically insoluble in all solvents, does not result in the pollution to tube fluid in therefore using. And politef coefficient of friction is low, do not result in bigger obstruction when pipeline 1 bends.

Pressurize layer 13 is made up of vinyon. Vinyon impact strength is higher, endurance, it is possible to make pipeline 1 remain to abundant pressurize after being repeatedly folded over.

Wearing layer 14 is formed by nylon braiding. Nylon has excellent mechanical strength and wearability, makes pipeline 1 be not easy abrasion, and its alternative metals can make pipeline 1 mass lighter.

Embodiment 2

As in figure 2 it is shown, and embodiment 1 be different in that: the sealing surface between pipeline 1 and joint 2 is coated with raw material band 3. Owing to pipeline 1 has multiple structure, the connection between each layer and joint 2 is not good at causing water clock, uses the sealing that the outlet of raw material band 3 Clad pipe 2 just can improve between joint 2 and pipeline 1, it is to avoid dripping problems.

As in figure 2 it is shown, joint 2 is provided with the groove portion 21 surrounding pipeline 1 outlet outside, groove portion 21 is fixed with the conduction screw 4 penetrating pipeline 1. Conduction screw 4 can fix inner spring 11 and the position of outer spring 12 outer end, it is prevented that its retraction when bending deforms disconnects and the contacting of joint 2.

As in figure 2 it is shown, conduction screw 4 is connected with inner spring 11 and outer spring 12. Raw material band 3 is as non-conducting structure, it is possible to avoid it to affect the antistatic effect of flexible pipe; Adopting conduction screw 4 to fix, inner spring 11 can pass through conduction screw 4 with outer spring 12 and connect joint 1, it is ensured that conductive path turns on, and ensures antistatic effect.

Above-described is only embodiments more of the present utility model. For the person of ordinary skill of the art, under the premise creating design without departing from this utility model, it is also possible to making some deformation and improvement, these broadly fall into protection domain of the present utility model.
