Description

Technical Field

[0001] The utility model relates to a water distributor adapter, more particularly to a pipeline joint assembly and a water distributor adapter. Background Art

[0002] The manifold is a water distribution and collection device used to connect the supply and return water lines in the water floor heating system. According to the inlet and return water, it can be divided into manifolds and collectors, which are usually collectively referred to as manifolds; the connection of the supply and return lines requires floor heating pipes. There are many specifications of floor heating pipes on the market, the more common ones are DN20 and DN16; therefore, in order to meet market demand, the manifold needs to be adapted to a variety of floor heating pipe specifications. The manifold adapters on the market include floor heating pipe joints, clamps and union nuts. Figure 1 The figure shows the existing DN20 floor heating pipe water distributor adapter structure. Figure 2 The diagram shows the adapter structure for the manifold for DN16 floor heating pipes. The existing clamping ring is a hollow cylinder with a notched groove. Because the clamping ring must provide radial force to the floor heating pipe, it requires a certain degree of deformation. This makes it difficult to arbitrarily adjust the thickness of the inner and outer surfaces of the clamping ring. Consequently, the inner diameter of the union nut must change with the outer diameter of the clamping ring during the connection process. When replacing DN20 floor heating pipes with DN16 floor heating pipes, three components must be replaced: the floor heating pipe fitting, the clamping ring, and the union nut. The greater the number of components, the higher the manufacturer's investment costs and the more complex the replacement process. Utility Model Content

[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: a pipe joint assembly comprising a union nut and a retaining ring. The retaining ring has an outer wall provided with a contact portion that abuts against the inner wall of the union nut, thereby pushing the retaining ring radially to contract via the inner wall of the union nut.

[0007] As a further improvement of the present invention, a breaking groove is provided on the clamping ring.

[0008] As a further improvement of the present invention, the rupture groove has an upper portion and a lower portion, and the upper portion and the lower portion are staggered with each other to form a guiding contact surface between the upper portion and the lower portion to guide the shrinkage of the clamping ring.

[0009] As a further improvement of the present invention, serrations are provided on the inner side wall of the clamping ring.

[0010] As a further improvement of the present invention, a water diverter adapter includes a valve body, a union nut, a joint, and a clamping ring. The outer wall of the clamping ring is provided with a resisting portion, which abuts against the inner wall of the union nut to push the clamping ring radially contracting through the inner wall of the union nut.

[0011] As a further improvement of the present invention, a first conical surface is provided on the interference portion, a second conical surface is provided on the union nut, and a third conical surface is provided on the valve body.

When the joint is installed into the valve body, the second joint limiting end face is abutted against the valve body limiting end face, and the first joint limiting end face cooperates with the end face of the external floor heating pipe.

[0013] As a further improvement of the present invention, a valve body limiting inner circular surface is provided in the valve body, and a joint outer circular surface is provided on the joint, and the joint outer circular surface cooperates with the inner wall of the external floor heating pipe. A first outer circular surface is formed on the outer wall of the clamping ring, and a second outer circular surface is formed on the side of the interference portion facing away from the clamping ring. The first outer circular surface and the second outer circular surface are connected by a first conical surface. A first limiting surface and a second limiting surface are provided on the inner side wall of the union nut, and the first limiting surface and the second limiting surface are connected by a second conical surface. When the first conical surface and the second conical surface cooperate with each other, the second limiting surface cooperates with the second outer circular surface. The first outer circular surface is divided into two parts, one part cooperates with the valve body limiting inner circular surface, and the other part cooperates with the first limiting surface.

[0014] The beneficial effect of the present invention is that a changeable interference portion is provided on the outer wall of the clamping ring for cooperating with the union nut to realize radial contraction action, so that when the inner diameter of the clamping ring is changed, the outer diameter of the outer portion for cooperation remains unchanged. Compared with the method in the prior art, when the DN20 floor heating pipe is replaced with the DN16 floor heating pipe, the union nut can be universal, reducing the number of parts to be replaced and reducing costs.

The outer wall of the snap ring 4 forms a first outer circular surface 42. The snap ring 4 is provided with a broken groove 43. The broken groove 43 is as shown in FIG. Figure 8 As shown, the midline of the thickness of the clamping ring 4 is used as the dividing point to divide it into two parts, upper and lower, forming two steps. The stepped surfaces of the two steps contact each other to form a guiding contact surface, so that the clamping ring 4 is not prone to axial deformation during contraction. The outer wall of the trapezoidal piece forms a second outer cylindrical surface 44, and the inner wall of the clamping ring 4 is provided with serrations 45. During the assembly process, first put the union nut 2 and the clamping ring 4 on the floor heating pipe in turn, and the first limiting surface 23 and the serrations 45 respectively match the outer circle of the floor heating pipe; then insert the joint 3 into the floor heating pipe, and the outer cylindrical surface 31 of the joint matches the inner wall of the floor heating pipe, and the first joint limiting end face 32 matches the end face of the floor heating pipe; then insert the valve body 1, and the second joint limiting end face 33 matches the valve body limiting end face 13; then push the clamping ring 4 axially along the outer circle of the floor heating pipe toward the valve body 1, and push it until the first conical surface 41 and the third conical surface 11 match in place. , the first outer surface 42 of the clamping ring 4 cooperates with the valve body limiting inner surface 14 of the valve body 1; finally, the nut thread 22 of the locking union nut 2 and the valve body thread 12 of the valve body 1 are connected. Through the cooperation of the second conical surface 21, the first conical surface 41 and the third conical surface 11, the clamping ring 4 generates radial force on the floor heating pipe. In addition, the outer surface 31 of the joint supports the inner wall of the floor heating pipe, so that the serrations 45 are embedded in the outer wall of the floor heating pipe.

The fixing methods of DN16 and DN20 are the same. The difference is that the joint 3 and the clamping ring 4 are different. The other parts are universal. Compared with Figure 1 and Figure 2 The different floor heating pipe adapters shown reduce the types of union nuts and universal union nuts.
