Abstract
The utility model relates to a lightning protection connecting piece of a gas pipe network. The lightning protection connecting piece is used for insulating an outdoor gas supply upright metal pipeline and an indoor gas supply metal pipeline, so as to realize lightning protection. In the lightning protection connecting piece, two stainless steel pipe connectors with zigzag tooth ends are respectively inserted into two ports of an insulating rubber pipe. Then outer circles at the two ends of the insulating rubber pipe are respectively sleeved with a fixed clamping sleeve. At last, the outer circles of the two fixed clamping sleeves are sleeved with a rubber sheath respectively, thereby forming the lightning protection connecting piece. The lightning protection connecting piece of the gas pipe network is simple and compact in structure, convenient in manufacturing and installation, reliable in safety performance, and can effectively prevent the thunder from entering the houses, thereby ensuring the safety of lives and property of people.
Description
Affiliated technical field
The utility model relates to a kind of link in the gas pipeline, specifically is a kind of lightning protection link of gas ductwork.
Background technique
The outdoor gas of present most of residential buildings carries the upright metallic pipeline all not take the lightning protection insulation measures, especially in some tall buildings because of construction or all multifactor influences such as building structure, facilitate combustion gas to carry the upright metallic pipeline to install on the body of wall out of doors again.This root upright metallic delivery pipe is as if no lightning protection measures, and its thunder and lightning will be introduced indoor by the combustion gas arm of registering one's residence, and causes the danger of personal injury and property loss.Therefore existing gas ductwork presses for a kind of link of registering one's residence with lightning protection effect.
Summary of the invention
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, and provides a kind of simple in structure, safe and reliable, can make outdoor gas carry the gas ductwork lightning protection link that insulate between upright metallic pipeline and the indoor gas transferring metal pipeline.
The purpose of this utility model realizes by following technical measures: this gas ductwork lightning protection link includes fixedly cutting ferrule of two stainless steel joint for pipeline, insulation rubber pipe, two, wherein have zigzag tooth mouth on one of each stainless steel joint for pipeline the cylindrical, and be provided with the location end face at the afterbody of tooth mouth.These two stainless steel joint for pipeline all will have the serrated teeth mouth respectively that respectively be inserted in the two-port of insulation rubber pipe, and allow the end face of location end face in the not steel pipe joint and insulation rubber pipe by the jail, realize that axially locating stops these two stainless steel joint for pipeline and contact.And two fixedly cutting ferrule be to be set on the cylindrical at insulation rubber pipe two.Also fixedly put a rubber sheathing again on the cylindrical of cutting ferrule at last at these two.
This gas ductwork lightning protection link is owing to will be connected with the pipe joint miscellaneous in the gas ductwork, therefore the other end style of stainless steel joint for pipeline is a straighttube-type in the utility model, or two cards pressures are adhered, or two clamp-press type, or the ring pressure type.
The utility model beneficial effect compared with prior art is that this gas ductwork lightning protection link is simple and compact for structure, and fabrication and installation are convenient, and Safety performance is reliable, can prevent effectively that thunder and lightning from swarming into indoorly, guarantees the safety of people's life and property.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is that two cards are pressed adhered stainless steel joint for pipeline.
Fig. 3 is the stainless steel joint for pipeline of two clamp-press types.
Fig. 4 is the stainless steel joint for pipeline of ring pressure type.
The figure number explanation
1. fixing cutting ferrule 4. stainless steel joint for pipeline of insulation rubber pipe 2. rubber sheathings 3.
Embodiment
The utility model is further described below in conjunction with drawings and Examples: this gas ductwork lightning protection link by two stainless steel joint for pipeline 4, insulation rubber pipe 1, two fixedly cutting ferrule 3 and a rubber sheathing 2 are formed.On wherein one the cylindrical of each stainless steel joint for pipeline 4, have zigzag tooth mouth, and be provided with the location end face at the afterbody of tooth mouth.And the other end of each stainless steel joint for pipeline 4 is to be used for being connected with the pipe joint of gas ductwork, and its style is a straighttube-type, or two card pressure is adhered, or two clamp-press type, or the ring pressure type.These two stainless steel joint for pipeline 4 are that that will have the serrated teeth mouth respectively respectively is inserted in the two-port of insulation rubber pipe 1, but also to allow on each stainless steel joint for pipeline 4 the location end face will with the end face of insulation rubber pipe 1 by the jail, realize axially locating.The end face of these two stainless steel joint for pipeline 4 in insulation rubber pipe 1 be from, any contact must not be arranged.And two fixedly cutting ferrule 3 be to be set on the cylindrical at insulation rubber pipe 1 two, come stainless steel joint for pipeline 4 is reinforced with this.Also fixedly put a rubber sheathing 2 again on the cylindrical of cutting ferrule 3 at last at these two.
When this gas ductwork lightning protection link uses, be it to be installed in outdoor gas carry between upright metallic pipeline and the indoor gas transferring metal pipeline.Be that it is laid in the wall bushing of each household during installation, outdoor gas is carried between upright metallic pipeline and the indoor gas transferring metal pipeline and has just been formed insulation like this, can prevent thunderbolt effectively.
Claims (2)
1. gas ductwork lightning protection link, include two stainless steel joint for pipeline (4), an insulation rubber pipe (1), two fixing cutting ferrules (3), it is characterized in that having zigzag tooth mouth on one the cylindrical of each stainless steel joint for pipeline (4), and be provided with the location end face at the afterbody of tooth mouth, these two stainless steel tube heads (4) all will have the serrated teeth mouth respectively that respectively be inserted in the two-port of insulation rubber pipe (1), and allow the end face of location end face on the stainless steel joint for pipeline (4) and insulation rubber pipe (1) by the jail, the realization axially locating is stopped these two stainless steel joint for pipeline (4) and is contacted, and two fixedly cutting ferrule (3) be to be set on the cylindrical at insulation rubber pipe (1) two, also fixedly put a rubber sheathing (2) again on the cylindrical of cutting ferrule (3) at last at these two.
2. gas ductwork lightning protection link according to claim 1 is characterized in that the other end style of stainless steel joint for pipeline (4) is a straighttube-type, or two card pressure is adhered, or two clamp-press type, or the ring pressure type.
