Electric shock-proof joint for pipeline system

Abstract

The invention relates to an electric shock-proof joint for a pipeline system. The electric shock-proof joint is composed of a first insulating joint, a second insulating joint and a built-in insulating piece, wherein the first insulating joint can be a plastic piece or a plastic metal composite piece, one end of the first insulating joint is provided with an interface which is connected with other pipeline fittings, and the other end of the first insulating piece extends downward and is connected with the second insulating joint in a sealing mode after the other end of the first insulating joint is sleeved with the built-in insulating piece; the second insulating joint can be a plastic piece or a plastic metal composite piece, one end of the second insulating joint is provided with an interface which is connected with other pipeline fittings, and the other end of the second insulating piece is connected with the first insulating joint in a sealing mode and presses the built-in insulating piece tightly. The outer side surface of the built-in insulating piece is provided with a spiral groove, a spiral type flow channel is formed between the spiral groove and the inner wall of the first insulating joint, and on the premise of ensuring the length of the flow channel, the whole width of the flow channel is shortened, and further the whole height of the electric shock-proof joint is shortened.

Description

Technical field: [0001] The invention relates to the technology of protection against electric shock, in particular to the protection against electric shock of a fluid delivery pipeline system, in particular to an anti-shock joint used for the pipeline system. Background technique: [0002] In the prior art, the anti-shock technology of the pipeline system generally adopts grounding measures. However, the effect of the grounding measures depends on the grounding effect of the original electrical system, which has certain limitations. Alternatively, plastic pipes are used to transport the fluid. However, the fluid in the pipes often has a certain degree of electrical conductivity, which also limits the application effect of this measure. To make the fluid in the pipeline reach the required anti-shock level, it is often necessary to solidify a relatively slender flow channel in the pipeline to ensure that when there is an accidental electric leakage and someone gets an electri...
