Abstract
An improved fast connector for gas corrugated pipe relates to a connective part for metal corrugated pipe for gas. The technical proposal of the prior art has the disadvantages of poor temperature tolerance and poor safety. The utility model comprises a nut and a connector screwed with the internal wall of the nut, and is characterized in that a clipping ring arranged inside the nut is provided with a grip ring protruding inward, wherein, the clipping ring and the connector are respectively provided with a clipping surface matched with each other. The utility model has the advantages of good sealing effect, temperature resistance effect, stable function and safe use.
Description
[technical field]
The utility model relates to a kind of combustion gas link with metal bellows, specifically is a kind of fast connector that shallow endless metal bellows is connected with other pipe fitting of being used for.
[background technique]
Existing non-scale combustion gas only relies on the deformation of nonmetallic material to realize sealing with the rapid pipe joint of corrugated stainless steel tubing usually, but these nonmetallic material non-refractories, when being used in urgencies such as higher special occasions of some temperature or breaking out of fire, the nonmetallic material parts easily melt distortion and can't play normal sealing, locating effect, cause gas leakage in the pipe, Security is low.Therefore, this rapid pipe joint generally can only be applicable to the occasion below 300 ℃.
[model utility content]
In order to overcome the above-mentioned defective that exists in the prior art, the utility model provides a kind of modified model quick joint of corrugated pipe for gas, to guarantee the sealability under high temperature condition, reaches working stability, safe and reliable purpose.
For this reason, the utility model is by the following technical solutions: the modified model quick joint of corrugated pipe for gas, comprise nut and the joint that is bolted in nut inner wall, it is characterized in that: be provided with a clamping ring in the described nut, this clamping ring is provided with to projecting inward pressure ring, and described clamping ring and joint are provided with the gripping surface that matches.During installation, earlier bellows is inserted in the nut, the pressure ring of clamping ring is stuck in the wave trough of bellows, and the right-hand member of bellows exceeds the gripping surface of clamping ring, and joint then connects other pipe fitting (standard pipe).Then nut is screwed into joint, in this process, gripping surface on clamping ring and the joint cooperates and gradually the bellows right-hand member is exceeded the clamping ring gripping surface and partly flattens, and bellows is closely pasted mutually with joint and forms sealing; Pressure ring has been fixed the axial position of bellows, has guaranteed that bellows can not produce slip.Clamping ring of the present utility model, joint and nut are all made with metallic material, and it is strong to bear high temperature capabilities, has guaranteed still can have better seal when some special occasions or breaking out of fire, safe.
Gripping surface on the described joint is an end face of being located at a boss in joint left side, and the boss outer rim is around being provided with nonmetal seal ring, and the left side of this nonmetal seal ring exceeds the boss end face.Nonmetallic ring can be made with plastics, rubber material.Install in rapid pipe joint, the gripping surface on clamping ring and the joint cooperate gradually the bellows right-hand member is flattened in, bellows outwards extends along the space between the gripping surface gradually until offseting with nonmetal seal ring inboard and making nonmetal seal ring produce deformation and form soft seal, has further improved sealability.The left side of described nonmetal seal ring exceeds boss end face 0.1～0.5mm and is advisable.
The described clamping ring outside is provided with male cone (strobilus masculinus), and the nut inboard is provided with corresponding inner conical surface.In the connection procedure of nut and joint, the inner conical surface of nut and the male cone (strobilus masculinus) of clamping ring offsets and clamping ring is applied inside active force tightly is embedded in the wave trough of bellows pressure ring, guarantees linking intensity and airtight quality.
Inboard, described nut left end hole is provided with seal ring.Common combustion gas is wrapped with plastic protective sleeve with corrugated stainless steel tubing, and seal ring is used for the space between sealing nut left end hole and the bellows protecting jacket, reaches the purpose of waterproof and dustproof.
Described joint right side is provided with outside thread or internal thread, is convenient to connection pipe fitting.
Beneficial effect: the utility model has reached assurance sealing effect, resistant to elevated temperatures purpose by improving the sealing configuration of rapid pipe joint, and working stability is safe in utilization.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
[embodiment]
Modified model quick joint of corrugated pipe for gas as shown in Figure 1 comprises nut 1 and the joint 2 that is bolted in nut 1 inwall, is provided with clamping ring 3 in the nut 1, and clamping ring 3 is provided with to projecting inward pressure ring 11, and the quantity of pressure ring 11 and position can be provided with according to actual needs.Clamping ring 3 left sides are provided with male cone (strobilus masculinus) 12, and nut 1 inboard is provided with corresponding inner conical surface 13.Clamping ring 3 right-hand members and joint 2 left ends are provided with corresponding left gripping surface 6 and right gripping surface 7, right gripping surface 7 is an end face of being located at a boss in joint 2 left sides, the boss outer rim is around being provided with nonmetal seal ring 5, and the left side of this nonmetal seal ring 5 exceeds the about 0.1～0.5mm of boss end face.
Joint 2 right sides are provided with outside thread 9, also can offer internal thread according to actual conditions.Nut 1 left port inboard also is provided with seal ring 8.Above-mentioned joint, nut and clamping ring all available copper or steel are made, and seal ring and nonmetal seal ring can be made with plastics such as teflon or rubber material.
During use, bellows 4 is inserted in the nut 1, pressure ring 11 is clipped near the wave trough of the mouth of pipe, is with plastic sheath 10 outside bellows is general, in the wave trough at seal ring 8 insert nuts 1 left port place, 2 of joints connect other pipe fitting.Then nut is screwed into joint, the joint left end stretches in the connection chamber, and left gripping surface 6 and right gripping surface 7 and nonmetal seal ring 5 cooperate the ripple with ripple mouth of pipe place to flatten, and make mouth of pipe complanation shape, thereby form sealing.
Claims (6)
