Abstract
The utility model discloses an antistatic buried bleeding-valve device for gas network, belonging to gas transmission is provided, including a metal ball valve body, a fused sleeve, a steel-plastic crossover connection, a wire, a head plug and a ground electrode. The plastic end of the steel-plastic crossover connection is connected with a discharging pipe by means of the fused sleeve, and the metallic end of the steel-plastic crossover connection is connected with the metal ball valve body by screw thread; the head plug is arranged at a discharging outlet of the metal ball valve body; the one end of the wire is connected with the metal ball valve body, and the another end is connected with the ground electrode; the surfaces of the metal ball valve body and the head plug have a fusion bonded epoxy powder anti-corrosion protection layer. The utility model has the advantages that a convenient operation and the metal ball valve carried through an anti-corrosion treatment, which has a same service life with the PE, can be embalmed directly without the need of constructing valve well; in addition, owing to the special wire on the metal ball valve is connected with the ground electrode so as to export the static carried by the discharging gas, therefore forming a intrinsically safe grounding and thus the hidden dangers of misoperation.
Description
Technical field
The utility model relates to a kind of relief valve device, relates in particular to a kind of gas ductwork and diffuses control valve unit with the antistatic directly buried type, belongs to the combustion gas transportation art.
Background technique
PE combustion gas tubing is with its excellent cost performance, progressively captured gas market from the seventies in 20th century, in the PE pipe, flowed, will produce static inevitably but combustion gas especially contains the combustion gas of dust, this static constitutes a threat to safety when especially purging diffuses at construction operation.Therefore ISO/TS 10839 " combustion gas is carried with polyvinyl piping materials and pipe fitting design, carrying and installation specification ", China CJJ63 " fuel gas polyethylene pipeline engineering rules ", in the rules standards such as Australia AS 3723 " combustion gas with the installation and the maintenance of plastic systems " all to preventing that the electrostatic hazard problem from having proposed warning and requirement, to adopt an effective measure when general requirement is construction or operation, prevent the harm of static.The way commonly used that prevents static is that organic fabric is drenched, and an end is wrapped on the pipeline, and an end is embedded in the moist soil, or PE pipe connection metal tube, and metal tube is ground connection again.The valve that diffuses of PE ball valve both sides is used for two kinds of situations, and the one, the emergency diffusion under the accident condition, the 2nd, diffusing during maintenance.Now diffusing valve shows for PE valve existing problems: the one, and will diffuse mouth fast and cause its place's adapter difficulty, the 2nd, in emergency circumstances ignore problem with grounding easily, constitute accident potential.
Summary of the invention
The purpose of this utility model provides a kind of gas ductwork and diffuses control valve unit with the antistatic directly buried type, and the utility model anti-static effect is good, can will diffuse that mouthful to cause suitable place easy to operate, safe by being threaded fast.
For realizing above-mentioned model utility purpose; the technical solution of the utility model is achieved in that gas ductwork of the present utility model diffuses control valve unit with the antistatic directly buried type; comprise a Metal Ball valve body; the electric smelting sleeve; steel is moulded crossover connection; lead; pipe plug and earth electrode; steel is moulded plastics one end of crossover connection with described electric smelting sleeve and the outer end of exhaust stack is tightly connected; the metal end that steel is moulded crossover connection and Metal Ball valve body are by being threaded; the mouth that diffuses at the Metal Ball valve body is provided with pipe plug; one end of described lead is connected on the Metal Ball valve body; the other end connects earth electrode, and described Metal Ball valve body and pipe plug surface are coated with the clinkery epoxy powder corrosion protective covering.
It is to adopt the method for electric smelting welding that it is welded together that the outer end that described electric smelting sleeve is moulded plastics one end of crossover connection and exhaust stack with steel is tightly connected.
It is to adopt brazing to meet the lead seal hole place that mode is fixed on the Metal Ball valve body to form an electrode that one end of described lead is connected on the Metal Ball valve body.
Described clinkery epoxy powder is the SN-106 clinkery epoxy powder that Shanghai Saineng Oil Pipeline Specialty Coatings Co., Ltd produces.
The beneficial effects of the utility model:
1, will diffuse ball valve and change the internal thread metal ball-valve into, can will diffuse mouth by being threaded fast and cause suitable place, convenient to operation.
2, through antiseptic metal ball-valve, but direct-burried need not built valve pit by laying bricks or stones, and with the same equivalent life of PE.
3, the special wire on the metal ball-valve links to each other with earth electrode, derives and diffuses the entrained static of gas, constitutes " essential safe type " ground connection, prevents the hidden danger of misoperation.
But 4, diffuse a mouthful setting pressure table in case of necessity, do interim pressure-measuring point and use.
