Abstract
The utility model relates to a connecting piece for a water inlet of a water inlet solenoid valve. A connecting pipe for the water inlet of the water inlet solenoid valve comprises a reducing straight tube with a large outer end and a small inner end, a soft silicone sealing ring and a hexagonal nut, wherein the hexagonal nut is connected with an outer side wall of the outer end of the reducing straight tube to form a whole; the soft silicone sealing ring is sleeved at the inner end of the reducing straight tube; an external thread is arranged on the reducing straight tube and is positioned between the soft silicone sealing ring and the hexagonal nut; and the outside diameter of the external thread is greater than that of the soft silicone sealing ring. No seal tape is needed to be wound on the external thread of the connecting pipe. The connecting pipe has the advantages of novel structure, no skidding in the thread screwing process, quickness and convenience in connection and favorable connecting effect.
Description
Technical field
The utility model relates to a kind of link that is used for the entering water electromagnetic valve water inlet.
Background technique
The existing connecting tube that is used for the entering water electromagnetic valve water inlet is to connect through the internal and external threads coupling; This connecting tube is the cylindrical shape straight tube; The inner is an outside thread; Earlier the outside thread place is twined during connection and go up the waterproof raw meal belt, and then clamp cylindrical shape straight tube outer side wall and select connecting tube is screwed into the entering water electromagnetic valve water inlet, the internal and external threads coupling is accomplished and is connected.Need twine the waterproof raw meal belt when this connecting tube connects at every turn, very trouble, and cylindrical shape straight tube outer side wall is skidded easily, is difficult to threaded together, connects weak effect.
Summary of the invention
The goal of the invention of the utility model provides a kind of entering water electromagnetic valve water inlet that is used for, and novel structure connects the connecting tube of quick and convenient and good connecting effect.
In order to reach the foregoing invention purpose, the technological scheme that the utility model adopted is:
A kind of connecting tube that is used for the entering water electromagnetic valve water inlet comprises the little reducing straight tube in big the inner, outer end, soft silica gel sealing ring and the hexagon nut that is connected as a single entity with the outer side wall of reducing straight tube outer end, and soft silica gel sealing ring is enclosed within the inner of reducing straight tube; The reducing straight tube is provided with outside thread, and outside thread is between soft silica gel sealing ring and the hexagon nut, and externally threaded external diameter is greater than the external diameter of soft silica gel sealing ring.
Adopt the connecting tube of said structure, comprise the little reducing straight tube in big the inner, outer end, seal ring and with the hexagon nut that the outer side wall of reducing straight tube outer end is connected as a single entity, can tighten threaded together through spanner and hexagon nut.The reducing straight tube is provided with outside thread, and the outside thread inboard is that the inner of reducing straight tube is with soft silica gel sealing ring, and the ability elastic deformability is strong after the soft silica gel sealing ring extruding, and its effect is exactly to realize waterproof before in the threaded connection place.Therefore just need not twine raw meal belt on the outside thread of above-mentioned connecting tube, novel structure, this connecting tube threaded together process is non-slip, connect quick and convenient, good connecting effect.
Description of drawings
Fig. 1: the utility model embodiment's structural representation.
Embodiment
Be to combine above-mentioned accompanying drawing that the technological scheme of the utility model is described in further detail below.
A kind of connecting tube that is used for the entering water electromagnetic valve water inlet as shown in Figure 1 comprises the little reducing straight tube 1 in big the inner, outer end, soft silica gel sealing ring 2 and the hexagon nut 4 that is connected as a single entity with the outer side wall of reducing straight tube outer end.Soft silica gel sealing ring 2 is enclosed within the inner of reducing straight tube.Reducing straight tube 1 is provided with outside thread 3, and outside thread 3 is between soft silica gel sealing ring 2 and the hexagon nut 4, and the external diameter of outside thread 3 is greater than the external diameter of soft silica gel sealing ring 2, and promptly soft silica gel sealing ring 2 tightly is enclosed within the less the inner of reducing straight tube 1 caliber.When connecting tube the inner screws in the inner thread mouth of entering water electromagnetic valve water inlet; Soft silica gel sealing ring 2 can receive axial compression; The ability elastic deformability is strong after soft silica gel sealing ring 2 extruding, and the elasticity distending is pressed on the threaded connection place, makes so just to realize waterproof before three-way pipe is in the threaded connection place; Need not twine raw meal belt, easy to connect and good water-proof effect.
