Abstract
The utility model discloses a stainless steel thread type connecting hose for gas. The stainless steel thread type connecting hose comprises a thread valve, a thread inner pipe and a stainless steel protection sleeve, and is characterized in that the thread valve is arranged at one end of the thread inner pipe, a connecting nut is arranged on the thread valve, the thread valve is fixedly arranged on the thread inner pipe, the thread inner pipe is a spiral corrugated pipe, inflaming retarding VTC hard plastic is arranged between the thread inner pipe and the stainless steel protection sleeve, the stainless steel protection sleeve is fixed outside the thread inner pipe through a clamping sleeve, the other end of the thread inner pipe is connected with a thread connector, a flange is arranged on the thread connector, and a sealing ring is arranged between the flange and the thread inner pipe. The stainless steel thread type connecting hose has the advantages of being good in sealing performance, long in service life and convenient to mount.
Description
Technical field
The utility model relates to a kind of combustion gas stainless steel thread type connecting hose, belongs to gas technology field.
Background technique
At present, the fuel tube that a lot of cities adopt is that zinc-plated welded steel pipe and rubber hose made, and this fuel tube is installed extremely inconvenient and constructed loaded down with trivial detailsly, and Safety performance is low.
Summary of the invention
For addressing the above problem, the utility model provides a kind of combustion gas stainless steel thread type connecting hose, comprise Thread valve, screw thread inner tube and stainless steel protecting cover, described Thread valve is installed in described screw thread inner tube one end, on described Thread valve, attaching nut is housed, described Thread valve is fixed in screw thread inner tube, described screw thread inner tube is spiral type corrugated pipe, fire-retardant VTC duroplasts is housed between described screw thread inner tube and stainless steel protecting cover, described stainless steel protecting cover is fixed on screw thread inner tube outside by cutting ferrule, described screw thread inner tube the other end connecting thread interface, described jointing mounting flange, between described flange and screw thread inner tube, be lined with seal ring.
Preferably, in described screw thread, tube thickness is not more than 0.2mm, and diameter is not less than 15mm.
Preferably, described fire-retardant VTC duroplasts thickness is not more than 1mm.
Advantage of the present utility model is: (1) is safe and reliable, and by the Placement of stainless steel protecting cover and screw thread inner tube suit, side seal, can effectively avoid Leakage Gas; (2) installation efficiency is high, only needs special stage property can complete installation; (3) long service life; (4) be applicable to secretly set.
