Preferably, the end of the body has a bottom surface, and the bottom surface is flush with the flat end surface.

Preferably, the height of the inner ring is less than the height of the outer ring to form a step therebetween.

Preferably, the outer ring completely covers the inner ring.

Preferably, the snap ring is made of plastic.

Preferably, two ends of the snap ring close to the opening are formed, and notches are formed at the two ends of the snap ring.

Preferably, the notch is in an "L" shape.

Preferably, the notch divides the outer ring into a first region and a second region, the first region is arranged in a protruding manner at the tail end relative to the second region, and the inner ring is arranged in the second region.

The utility model discloses a back is accomplished in the three-way valve equipment, and the clearance between body and the loose joint nut inner wall just in time can be filled to the lateral wall of its opening snap ring, makes simultaneously sealed one of them plane of pad support when the pressurized and press on the plain end face of opening snap ring, and then has guaranteed the sealing performance of this three-way valve, effectively avoids sealed the pad to be cut apart because of the fault-tolerant problem and produce the problem of leaking. The utility model discloses the three-way valve structure function of this kind of design is stable to can reduce the cost by a wide margin, and then can show improvement market competition.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to the attached drawings 1 to 5 in the specification, a three-way valve structure comprises a body 1, a loose joint nut 2, a sealing gasket 3 and a split snap ring 4, wherein the split snap ring 4 is provided with an opening 40 to form a non-closed ring structure, and the split snap ring 4 can be made of plastic materials; the snap ring 4 comprises an outer ring 4a and an inner ring 4b, the outer ring 4a has an outer side wall a and a flat end face b, preferably, the height of the inner ring 4b is lower than that of the outer ring 4a so as to form a step c therebetween, and the outer ring 4a completely covers the inner ring 4 b; the side surface of the tail end of the body 1 is provided with a groove 1a and a bottom surface c, when the device is assembled, the inner ring 4b is clamped in the groove 1a of the body for connection, at the moment, the flat end surface b of the split snap ring and the bottom surface c of the body 1 are positioned on the same plane, and then the sealing gasket 3 is connected to the body 1 by using a loose joint nut 2; after the equipment is accomplished like this, the clearance between body 1 and the loose joint nut inner wall just in time can be filled to the lateral wall of this outer loop 4a, makes sealed 3 one of them plane of filling up support when the pressurized press on plain end face b simultaneously, and the plain end face b of this opening snap ring flushes mutually with the bottom surface c of body 1 promptly, and then has guaranteed the sealing performance of this three-way valve to effectively avoid sealed the problem of filling up to produce the problem of leaking because of the disconnected poor problem is sheared off.

Preferably, referring to fig. 5, the cross-sectional shape of the snap ring 4 is "L" shape, that is, one end surface of the outer ring 4a and the inner ring 4b is on the same horizontal plane.

Further, two ends of the snap ring 4 are formed near the opening 40, and two symmetrical "L" shaped notches 43 are formed at two ends of the snap ring 4. Preferably, the gap 43 divides the outer ring 4a into a first area 41 and a second area 42, the first area 41 is disposed at the end of the snap ring protruding relative to the second area 42, wherein the inner ring 4a is disposed in the second area 42, thereby facilitating the assembly between the snap ring and the body. The utility model discloses the three-way valve structure function of this kind of design is stable to can reduce the cost by a wide margin, and then can show improvement market competition.
