Abstract
The utility model discloses a novel nut for the connection of pipelines. The utility model is mainly characterized in that a concave table is arranged on the sealing contact end surface of a connecting body (1) and a connecting body (4), and a metal spring washer (2) is embedded in the concave table. The contact end of the metal spring washer (2) and the connecting body (4) is in a symmetrical conical surface along a shaft line. The contact end of the connecting body (4) and the metal spring washer (2) is in a spherical surface. The utility model has the advantages of effective enhancement for sealing performance, long service life, etc., and is used for the field of the connection of pipelines with the nut.
Description
The utility model relates to a kind of pipeline connection conjunction, and specifically a kind of new-type pipeline connects with living female.
At present, be used for industry and civilian installation, general pipeline enclosures such as conveying water, oil, gas connect appliance, and commonly used has flat pattern alive female and tapered alive female.Flat pattern is lived female, needs to use rubber ring seal, and long-term use can produce aging, influences hydraulic pressure and sealing; The tapered mother that lives makes troubles for production and life because genus line contact between sealed interface easily is corroded, and sealing is poor, has increased the workload of safeguarding and keeping in repair.
The purpose of this utility model is to manufacture and design a kind of the change under the prerequisite that has female basic structure of living now, can effectively improve female sealing, pressure-bearing property that connects of living, and the novel pipeline connection that improves its working life is female with living.
The utility model is realized as follows:
A kind of new-type pipeline connects with living female, the intermediate connector (3) that comprises connecting body (1), connecting body (4), the body that is located by connecting (1) and connecting body (4), its characteristics are that described new-type pipeline connects the sealing with connecting body (4) with the mother's that lives connecting body (1) and contacts end face and be provided with concave station, described concave station is embedded with metallic elastic packing ring (2), described metallic elastic packing ring (2) is along tapered of the axis symmetry with the contact jaw of connecting body (4), and described connecting body (4) is spherical with the contact jaw of metallic elastic packing ring (2).
The contact jaw of described metallic elastic packing ring (2) and connecting body (4) is 90 ° along tapered drift angle of axis symmetry, and described metallic elastic packing ring (2) is made for copper material.
Compared with the prior art the utility model has following advantage: the one, and female sealing of living effectively improves, and is through the 24kg/cm2 hydrostatic test, non-leakage; The 2nd, simple in structure, can effectively guarantee axis of thread angle error ± 17 ' in; Three are to use the life-span long, significantly reduce the working service time.
Now in conjunction with the accompanying drawings, enumeration embodiment of the present utility model.
Fig. 1 is an overall structure sectional view of the present utility model.
New-type pipeline connects with living female, the intermediate connector (3) that comprises connecting body (1), connecting body (4), the body that is located by connecting (1) and connecting body (4), it is characterized in that described new-type pipeline connects the sealing with connecting body (4) with the mother's that lives connecting body (1) and contacts end face and be provided with concave station, described concave station is embedded with metallic elastic packing ring (2), described metallic elastic packing ring (2) is along tapered of the axis symmetry with the contact jaw of connecting body (4), and described connecting body (4) is spherical with the contact jaw of metallic elastic packing ring (2).
The contact jaw of described metallic elastic packing ring (2) and connecting body (4) is 90 ° along tapered drift angle of axis symmetry, and described metallic elastic packing ring (2) is made for copper material.
Take thread forms to be connected the location between connecting body (1) and the intermediate connector (3).
Claims (2)
1, a kind of new-type pipeline connects with living female, the intermediate connector (3) that comprises connecting body (1), connecting body (4), the body that is located by connecting (1) and connecting body (4), it is characterized in that described new-type pipeline connects the sealing with connecting body (4) with the mother's that lives connecting body (1) and contacts end face and be provided with concave station, described concave station is embedded with metallic elastic packing ring (2), described metallic elastic packing ring (2) is along tapered of the axis symmetry with the contact jaw of connecting body (4), and described connecting body (4) is spherical with the contact jaw of metallic elastic packing ring (2).
2, connect with living femalely by the described new-type pipeline of claim 1, the contact jaw that it is characterized in that described metallic elastic packing ring (2) and connecting body (4) is 90 ° along tapered drift angle of axis symmetry, and described metallic elastic packing ring (2) is made for copper material.
