Abstract
The utility model provides a cone seal welding type three-way pipe joint. The cone seal welding type three-way pipe joint comprises a three-way pipe joint body and three sets of joint assemblies, each joint assembly set comprises an O-shaped ring, a locking nut and a welded tube, the three-way pipe joint body is coaxially connected with the welded tubes through threads, and the locking nuts are respectively disposed outside connecting positions of the three-way pipe joint body and the welded tubes; an end face of the three-way pipe joint body where the three-way pipe joint body is contacted with each welded tube is an inner cone surface, an end face of each welded tube where each welded tube is contacted with the three-way pipe joint body is an outer cone surface, and a cone metal sealing surface at a tangential direction is formed by each inner cone surface and the corresponding outer cone surface; and the O-shaped rings are respectively disposed on the cone metal sealing surfaces. Each cone metal sealing surface is disposed between the three-way pipe joint body and the corresponding welded tube, one O-shaped ring that can be changed with pressure is used to achieve another soft seal, and therefore the joint is provided with lasting leakproofness and clamping function.
Description
Technical field
The utility model belongs to three-way union field, is specifically related to the three-way union of a kind of cone seal welding type.
Background technique
Three-way union is a kind of of pipe fitting, and its Connecting format is exactly directly by threeway and steel pipe butt welding, and still, current three-way union in use, is difficult to ensure its sealing of card.
Model utility content
The utility model is for above-mentioned the deficiencies in the prior art, and the sealing that can provide lasting and the cone seal welding type three-way union of clamping function are provided.
The utility model is achieved by the following technical solution:
The three-way union of a kind of cone seal welding type, it is characterized in that, comprise three-way union body and three groups of adapter assemblies, described every group of adapter assembly includes O type circle, locking nut and welded pipe, three-way union body is coaxially connected by screw thread with welded pipe, and the outer installment of described three-way union body and welded pipe joint has locking nut; The end face that described three-way union body contacts with welded pipe is an inner conical surface, and the end face that described welded pipe contacts with three-way union body is a male cone (strobilus masculinus), and described inner conical surface and male cone (strobilus masculinus) form the cone-shape metallic leak-proof face of a tangent direction; On described cone-shape metallic leak-proof face, be provided with O type circle.
Further setting of the present utility model is, the cone angle of described cone-shape metallic leak-proof face is 24 °.
Further setting of the present utility model is, is provided with a groove on the male cone (strobilus masculinus) of described welded pipe, and described O type circle is embedded in described groove.
Cone seal welding type described in the utility model three-way union is connected welded pipe by butt welding welding manner with the end of pipe, form one.In the inner conical surface of three-way union body and welded pipe, on male cone (strobilus masculinus), form the metallic sealing section of a tangent direction, the O shape circle that simultaneously adopts a meeting to change with pressure, realizes another soft seal.The utility model is by spiral way, guarantees that joint can never divide to pull open.The friction that welded pipe head and screw thread are subject to, the combination force of screw thread itself and the acting in conjunction of cone, make this joint have lasting sealing and clamping function.
Accompanying drawing explanation
Fig. 1 is the structural drawing of cone seal welding type described in the utility model three-way union.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, the utility model provides the three-way union of a kind of cone seal welding type, comprise three-way union body 1 and three groups of adapter assemblies, described every group of adapter assembly includes O type circle 2, locking nut 3 and welded pipe 4, three-way union body 1 is coaxially connected by screw thread with welded pipe 4, and described three-way union body 1 has locking nut 3 with the outer installment of welded pipe 4 joints; The end face that described three-way union body 1 contacts with welded pipe 4 is an inner conical surface, and the end face that described welded pipe 4 contacts with three-way union body 1 is a male cone (strobilus masculinus), and described inner conical surface and male cone (strobilus masculinus) form the cone-shape metallic leak-proof face of a tangent direction; On described cone-shape metallic leak-proof face, be provided with O type circle 2.On the male cone (strobilus masculinus) of described welded pipe 4, be provided with a groove, described O type circle 2 is embedded in described groove.The cone angle of described cone-shape metallic leak-proof face is preferably 24 °.
The sealing principle of above-mentioned cone seal welding type three-way union is:
1. by butt welding welding manner, welded pipe 4 is connected with the end of pipe, forms one.
2. with screw thread, welded pipe 4 and three-way union body 1 are coaxially felt relieved, and reach longitudinal transmission of power and interconnect by locking nut 3.Now, on the inner conical surface of three-way union body 1 and the male cone (strobilus masculinus) in welded pipe 4, form the soft seal of metallic sealing section and the O shape circle 2 of a tangent direction.
3. by spiral way, guarantee that joint can never divide to pull open.The friction that welded pipe 4 heads and screw thread are subject to, the combination force of screw thread itself and the acting in conjunction of cone, make this joint have lasting sealing and clamping function.
The installation instructions of above-mentioned cone seal welding type three-way union are as follows:
1. vertically cut steel pipe, accomplish fluently groove.
2. locking nut 3 is set in welded pipe 4, then welded pipe 4 and steel pipe is welded mutually.Cleaning weld, if desired polishing.Connecting the conical surface and groove must be clean, has no mechanical damage.
3. O shape circle 2 is put into groove, the size of O shape circle 2 must be suitable, and gap slightly between cell wall, and should be higher than the about 0.4～0.6mm of notch.
4. with the pipe of soldered splice, want straight and access three-way union body 1, do not make bending have stress.First with hand, twist firm locking nut 3, then tighten by suitable moment.For the purpose of reliable, with inflexible hand, fittings body is clamped.
It is apparent to one skilled in the art that the utility model can be changed into various ways, and such change is not thought and departed from scope of the present utility model.All so apparent modifications of the technician to described field, within being included in the scope of this claim.
