Description
Technical background
The utility model relates to seal for pipe joints field, is a kind of SEALING FITTING specifically.
Background technique
When changing water tap, need to add sealing material to seal, but when water tap does not rotate to correct position, more outside rotary swivel, sealing material can not be able to recover due to extruding when screwing in, thus cause poorly sealed, then do not have the effect of sealing when sealing material is very few, when sealing material is too much, water tap can not revolve, and uses the good joint of other sealings costly, a kind of sealing of current urgent need is better, the SEALING FITTING that price is lower.
Summary of the invention
The technological scheme that the utility model adopts for technical solution problem is: a kind of SEALING FITTING, comprises female joint, tool joint pin, nut and seal ring.The profile of female joint is taper, and the side be connected with tool joint pin is for hold greatly, and its Outside diameter is slightly larger than the external diameter of seal ring, is convenient to the insertion of seal ring and tool joint pin; The outer wall of female joint is provided with screw thread, and for attaching nut, its inwall is provided with annular convex, and its large end has some " V " shape groove, and its effect is when female joint taper is shunk, and ensures that female joint can not be squeezed fold; Described tool joint pin one end has annular groove, and annular convex can in embedded rings connected in star, and in order to realize the axial restraint of this joint, tool joint pin is connected with female joint with the cooperation of annular convex by annular groove; Described nut is connected by screw thread with female joint, during work, turns nut, makes mutually to compress between female joint and tool joint pin; Described seal ring is enclosed within tool joint pin, embeds in female joint together with tool joint pin, makes the better tightness of joint.
Described tool joint pin one end has annular groove, coordinates with the annular convex of female joint, owing to having seal ring between annular groove and annular convex, therefore annular groove width is larger than annular convex width.
Described female joint front end due to needs contraction, therefore can produce distortion, so female joint need adopt the good material of toughness, described tool joint pin adopts rigid material.
The beneficial effects of the utility model are:
(1). a kind of SEALING FITTING of the present utility model, utilizes taper contraction principle, realizes the sealing of joint, and easy to operate, structure simple, be easy to promote.
(2). a kind of SEALING FITTING of the present utility model, tool joint pin and the connecting ring connected in star of female joint and coordinating of annular convex, make the better tightness of joint.

Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of SEALING FITTING described in the utility model, comprise female joint 1, tool joint pin 2, nut 3 and seal ring 4, the profile of female joint 1 is taper, the side be connected with tool joint pin 2 is for hold greatly, and its Outside diameter is slightly larger than the external diameter of seal ring 4, be convenient to the insertion of seal ring 4 and tool joint pin 2; The outer wall of female joint 1 is provided with screw thread, and for attaching nut 3, its inwall is provided with annular convex 1a, and its large end has some " V " shape groove 1b, and its effect is when female joint 1 taper is shunk, and ensures that female joint 1 can not be squeezed fold; Described tool joint pin 2 one end has annular groove 2a, and annular convex 1a can in embedded rings connected in star 2a, and in order to realize the axial restraint of this joint, tool joint pin 2 carrys out female joint 1 by annular groove 2a with the cooperation of annular convex 1a and is connected; Described nut 3 is connected by screw thread with female joint 1, during work, turns nut 3, makes mutually to compress between female joint 1 and tool joint pin 2; Described seal ring 4 is enclosed within tool joint pin 2, embeds in female joint 1 together with tool joint pin 2, makes the better tightness of joint.
As shown in Figure 1 and Figure 5, a kind of SEALING FITTING described in the utility model, described tool joint pin 2 is provided with annular groove 2a, annular groove 2a matches with the annular convex 1a of female joint 1, for ensureing that seal ring 4 is not destroyed, described annular groove 2a width is greater than the width of described annular convex 1a.
During work, first nut 3 is enclosed within threadless one end in female joint 1, seal ring 4 is inserted in tool joint pin 2, then seal ring 4 is inserted together with tool joint pin 2 the taper leading portion of female joint 1, make annular convex 1a corresponding with annular groove 2a, then tightening nut 3, taper can be shunk gradually, annular convex 1a press against seal ring 4 and enters in annular groove 2a, when nut 3 front-end face overlaps with female joint 1 front-end face, namely stops the rotation.
More than show and describe basic principle of the present utility model, major character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; description in above-described embodiment and specification principle of the present utility model is just described; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
