Abstract
The utility model discloses a sealing device adopting hard connection and used for a gas pipeline of a water heater. The gas pipeline can be inserted into a gas inlet and is fixedly connected to the gas inlet via a clamp nut, wherein a metal sealing piece sleeved on the peripheral vertical plane of the gas pipeline is arranged at the connecting part between the gas inlet and the clamp nut; the upper end and the lower end of the sealing piece are conical surfaces; and the central outer diameter of the sealing piece is larger that the outer diameter of the upper and the lower ends of the sealing piece. In the sealing device, the metal sealing piece is sleeved on the gas pipeline, and is inserted into the gas inlet till reaching a positioning step; and then the gas pipeline is locked with the gas inlet via an outer hexagonal nut, so as to achieve a sealing effect. The sealing device provided by the utility model adopts a fully metal hard connection sealing, so that parts are not needed to be replaced during the use.
Description
Technical field
The utility model relates to water heater gas pipeline seal connection, specifically provides a kind of water heater gas pipeline hardwired seal arrangement.
Background technique
In the market gas pipeline and body gas inlet place be tightly connected that what generally take is to utilize asbestos packing sealing, but this asbestos packing is non-environmental-protecting material, and this material is not durable, and needs frequent renewal part.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of water heater gas pipeline hardwired seal arrangement, and this device is environmental and durable, be prone to processing, and easy for installation, Safety performance good.
The utility model for the technological scheme that solves its technical problem and adopt is: the hardwired seal arrangement of a kind of water heater gas pipeline; Gas pipeline can insert in the gas inlet and through tightening nut and be fixed on the gas inlet; And said gas inlet and tightening nut joint are provided with the metal seal that is sheathed on the gas pipeline periphery facade; Sealing part upper and lower end all is conical surface, and the center external diameter of sealing part is greater than its upper and lower end external diameter.
As the further improvement of the utility model, said Sealing is a metallic copper material.
As the further improvement of the utility model, said tightening nut is the outer-hexagonal nut, and this tightening nut interior edge face is provided with the cone structure that is complementary with said Sealing one end conical surface, to guarantee and the Sealing fit sealing.
As the further improvement of the utility model, said gas inlet lower end mouth inboard is provided with the cone structure that is complementary with Sealing the other end conical surface; And this gas inlet periphery facade is provided with screw thread, be able to reach with said tightening nut inner side surface on screw thread match, make tightening nut and gas inlet closely sealed.
As the further improvement of the utility model, be provided with a location step in the passage of said gas inlet, gas pipeline is inserted in the gas inlet can play positioning action.
The beneficial effect of the utility model is: through putting metal seal at gas pipeline; And the insertion gas inlet is interior until arriving at the positioning step place; Through the outer-hexagonal nut gas pipeline and gas inlet are carried out then sealed, thereby reach the effect of a sealing.This seal arrangement is entirely metallic hard and connects sealing, thereby in use need not with changing part.

Embodiment
Embodiment to the hardwired seal arrangement of a kind of water heater gas pipeline of the utility model is elaborated with reference to the accompanying drawings.
The hardwired seal arrangement of a kind of water heater gas pipeline of the utility model; Gas pipeline 1 can insert in the gas inlet and through tightening nut 2 and be fixed on the gas inlet 3; And said gas inlet and tightening nut joint are provided with the metal seal 4 that is sheathed on the gas pipeline periphery facade; The sealing part is a metallic copper material, and the Sealing upper and lower end all is conical surface, and the center external diameter of sealing part is greater than its upper and lower end external diameter.
In the present embodiment, said tightening nut is the outer-hexagonal nut, and this tightening nut interior edge face is provided with the cone structure that is complementary with said Sealing one end conical surface, to guarantee and the Sealing fit sealing.Said gas inlet lower end mouth inboard is provided with the cone structure that is complementary with Sealing the other end conical surface; And this gas inlet periphery facade is provided with screw thread, be able to reach with said tightening nut inner side surface on screw thread match, make tightening nut and gas inlet closely sealed.
Be provided with a location step 5 in the passage of said gas inlet, gas pipeline inserted in the gas inlet can play positioning action.
When present embodiment is installed; Earlier gas pipeline is put metal seal; And the insertion gas inlet is interior until arriving at the positioning step place; Through the outer-hexagonal nut gas pipeline and gas inlet are carried out sealedly then, in sealed process, thereby two conical surfaces on gas inlet and the tightening nut and metal seal extrusion-deformation reach the effect of a sealing.This seal arrangement is entirely metallic hard and connects sealing, thereby in use need not with changing part.
