Abstract
A union is provided. The exterior of a cylinder body provided with clip openings at two end is provided with a hexagonal nut, the middle part of the inner wall of the cylinder body is provided with an annular clip slot with the inside diameter the same as the cylinder body opening, the clip slot is provided with therein a gasket the same as the inside diameter of the cylinder body opening, and the gasket and the cylinder body opening are coaxial; and two opposite end surfaces of the nut are provided with therein corresponding square slotted holes whose length is the same as that of the end surface of the nut. Compared with the prior art, the union has the advantages of high clip-connection speed, high strength, long service life, convenience for mounting and debugging, etc.
Description
Technical field
The utility model relates to a kind of instrument pipe fitting, relates in particular to a kind of union.
Background technique
Union is a kind of pipe joint commonly used that can conveniently install and dismantle; Existing union agent structure is basic identical; Be that two ends are provided with the cylindrical shell middle part that is used for being connected with pipeline bayonet socket and are provided with and are used for fastening nut, the union of this structure exists in the process of practical application that clamping speed is slow, intensity is low and problem such as working life is short; In addition, existing the fastening of union mainly is to realize through turning nut, and utilize instrument for example the spanner nutting be because the influence of factors such as pipeline location and power thrusts, instrument is prone to and slides or skew, this just makes troubles to installment work.
Summary of the invention
The purpose of the utility model is to provide a kind of not only clamping speed fast, and intensity is high, long service life, and be convenient to install and adjustment, fabricating cost is low, structure, the simple union of technology.
The utility model mainly comprises cylindrical shell, nut and packing ring; Its middle cylinder body and nut are basic identical with existing technology; Be that the cylindrical shell outside that two ends are provided with bayonet socket is provided with hexagon nut; The internal diameter annular slot identical with cartridge openings offered at the middle part of cylinder inboard wall, is provided with the packing ring identical with the cartridge openings internal diameter in the draw-in groove, and this packing ring and cartridge openings coaxial line; Offer corresponding square slotted eye on two opposing end surfaces of above-mentioned nut, the length of slotted eye is identical with the end face length of nut.
The barrel of the utility model is established packing ring, then not only improves the clamping speed in the pipeline connection procedure, and makes joint strength height, long service life; In addition; During installation; Utilize instrument for example spanner can in turning the process of nut, can not make spanner occur sliding or skew like this being stuck in the slotted eye on two opposing end surfaces of nut of spanner owing to the influence of factors such as pipeline location and power thrusts; Make installation more convenient, increase work efficiency.
The utility model compared with prior art has following advantage:
1, clamping speed is fast, and intensity is high, long service life;
2, be convenient to install and adjustment, fabricating cost is low, and structure, technology are simple.
Description of drawingsFig. 1 looks generalized section for the master of the utility model.
EmbodimentIn the schematic representation of union shown in Figure 1; Cylindrical shell 2 outsides that two ends are provided with bayonet socket 1 are provided with hexagon nut 3; The internal diameter annular slot identical with cartridge openings 4 offered at the middle part of cylinder inboard wall, is provided with the packing ring 5 identical with the cartridge openings internal diameter in the draw-in groove, and this packing ring and cartridge openings coaxial line; Offer corresponding square slotted eye 6 on two opposing end surfaces of nut, the length of slotted eye is identical with the end face length of nut.
