This design makes the fitting easier to install and remove, while also providing better sealing performance. The inclined conical joint can be better connected with other pipelines, reduces the risk of leakage and ensures accurate fluid flow direction.

Further, a joint chamber 111 is provided in the joint main body 11, and a unidirectional structure is provided in the joint chamber 111. Providing a chamber in the joint body 11 for treating water flow can make the effect of the unidirectional structure more stable. The presence of the joint chamber 111 may accommodate both the unidirectional structure and also provide additional sealing properties. The design of the joint chamber 111 can effectively isolate the unidirectional structure from the external environment, protect it from the interference of external substances, and prolong its service life.

As shown in fig. 2, the first pipe 121 extends into the joint chamber 111 to form an inner joint 122, and the unidirectional structure is mounted on the inner joint 122. The nipple 122 is formed by extending the first pipeline 121, so that the unidirectional structure is more stable and reliable, and meanwhile, the unidirectional structure is directly arranged on the nipple 122, so that the stability and integration of the unidirectional structure and the nipple 122 can be ensured.

Further, the unidirectional structure further includes a valve housing body 141, the valve housing body 141 is sleeved on the outer side of the inner joint 122, and the valve housing body 141 extends to the side of the second joint 13 to form a conical tube 143.

Preferably, the valve sleeve body 141 extends toward the end of the first fitting 12 toward the interior wall of the fitting chamber 111 and has a retainer ring 142 that is interference fit with the fitting chamber 111. The fastening ring 142 and the valve sleeve body 141 are integrally designed, and can be integrally formed by injection molding and the like, and the material is preferably made of elastic members such as rubber.

The sealing performance of the nipple 122 and the one-way valve housing 14 is further enhanced by the provision of the retainer ring 142. The fastening ring 142 is located at a portion of the valve housing body 141 extending toward the inner wall of the joint chamber 111 toward one end of the first joint 12, and is interference fit with the joint chamber 111, thereby ensuring tight connection of the joints and preventing leakage.

Further, the fastening ring 142 forms an interference fit with both the inner joint 122 and the joint chamber 111, while the valve sleeve body 141 is also an interference fit with the inner joint 122, and the sealing effect of the one-way valve sleeve 14 with respect to the inner joint 122 is achieved through a plurality of interference fits.

Preferably, the surface of the two unidirectional valve plates 1431 facing the second joint 13 is a conical surface, the side edge of the conical surface can be a straight surface or an arc surface, preferably an arc surface, and when the arc surface receives the impact of water flow, the arc surface can play a role in guiding the flow more slowly, so that the effect of the unidirectional structure is more stable.

The angle of the tapered surface of the two check valve sheets 1431 toward the second joint 13 is preferably in the range of 15 to 75 degrees.

The principle of realizing unidirectional valve piece 1431 is that when two unidirectional valve pieces 1431 receive the impact of forward water flow, unidirectional valve port 1432 opens, and unidirectional joint is in conduction state. When the two unidirectional valve plates 1431 receive forward water flow impact, due to the existence of the conical surface, the unidirectional valve plates 1432 extend towards the first joint 12, and the water pressure received on the conical surface is gradually increased, so that the two unidirectional valve plates 1431 can be pressed under the action of the water pressure, further the unidirectional valve plates 1432 are closed, and the non-return effect is realized.

The one-way valve port 1432 includes two opposite and parallel closure surfaces that are configured to extend along the connector chamber 111 to ensure that the one-way valve port 1432 is effectively closed during operation to prevent backflow of fluid.

When the check valve port 1432 is closed, the two closing surfaces are tightly attached to achieve a sealing effect, so that the closing surfaces preferably extend along the direction of the joint chamber 111, because the direction of the chamber, that is, the direction of reverse impact of water flow, has a certain closing area along this direction, and the sealing effect can be achieved more effectively.

The conical tube 143 needs to receive the impact of the reverse water flow to realize the unidirectional function, so that two planes are needed to better realize the design purpose, while the conical tube 143 has the forward water flow impact inside and the forward water flow directly flows out of the unidirectional valve port 1432, so that the forward water flow can be guided to flow out of the unidirectional valve port 1432 more smoothly by the smooth and excessive curved surface inside.

It is further preferred that the sides of the two check valve plates 1431 are provided with V-shaped openings. The angle of the V-shaped opening depends on the size of the unidirectional valve port 1432, and the specific design requirement is that the V-shaped opening also realizes complete closure when the unidirectional valve port 1432 is closed, and the V-shaped opening extends in the direction of the unidirectional valve port 1432.

By designing the V-shaped opening, the sealing effect of the one-way valve sleeve 14 is further ensured, and no fine leakage occurs due to long-time one-way sealing use.

Further, the V-shaped opening extends to the inside of the tapered tube 143 to form a closed surface, and a good sealing effect is achieved by the fitting of the closed surface. While the provision of V-shaped openings increases the flexibility and sensitivity of the check valve plate 1431. The sides of the two check valve plates 1431 are provided with V-shaped openings, so that the check valve plates 1431 can respond to the pressure change of fluid better, and the normal operation of the check valve ports 1432 is ensured.

One end of the nipple 122 is connected with the first pipe 121 of the first joint 12, the other end stretches into the check valve sleeve 14, the end of the nipple 122 forms a platform, preferably, one end of the nipple 122 stretching into the check valve sleeve 14 is a horn-shaped opening, turbulence is prevented from being formed by water flow reciprocating impact to the end face, the starting position of the conical pipe 143 starts from the end of the nipple 122, the starting position of the conical pipe 143 coincides with the end of the nipple 122, the first pipe 121 stretches into the nipple 122 and then can smoothly transition to the check valve port 1432 through the inner wall of the conical pipe 143, and turbulence is also prevented from being formed by water flow reciprocating impact to the end face.

The unidirectional joint in this embodiment may be made by injection molding with two materials, filling the cavity with a material that is convenient to remove, and performing an integral injection molding, or may be made by injection molding the joint main body 11, the first joint 12 and the inner joint 122, where the joint chamber 111 is open in one direction toward the second joint 13, and after the additionally produced unidirectional valve sleeve 14 is mounted to the inner joint 122, the second joint 13 and the flange feature connected to the second joint 13 are welded to the joint main body 11, and the joint main body 11 is preferably made of a material such as plastic, which is inexpensive and practical, and can save production cost.
