Description

Technical Field

[0001] The invention relates to the technical field of drainage pipe fittings, and in particular to a building drainage assembly with a pressure-resistant structure. Background Art

[0002] There are many ways to connect the existing bathroom drainage pipes, including gluing, sealing ring flexible socket, clamp, groove, etc., all of which have the defects of low pressure bearing capacity leading to leakage, easy separation of pipes and fittings, short life, and great construction difficulty;

[0003] A Chinese patent document CN101196261A discloses a connecting pipe fitting, which includes a metal pipe, a top member buckle, a connecting joint, and a sealing gasket. The outer convex rib curved surface is arranged at the pipe mouth of the metal pipe; a sealing gasket is arranged between the outer convex rib curved surface of the connecting pipe in the connecting joint and the top member buckle, which is convenient for connection, reliable in sealing, convenient in operation, and improves work efficiency. However, the anti-slip and anti-leakage structures of the technical pipe fitting need to be optimized;

[0004] Therefore, we provide a building drainage assembly with a pressure-resistant structure to solve the above problems. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] The problem to be solved by the present invention is to provide a building drainage assembly with a pressure-resistant structure to overcome the defects in the prior art.

[0007] (II) Technical solution

[0008] In order to solve the technical problem, the present invention provides a building drainage assembly with a pressure-resistant structure, comprising a pipe fitting, wherein an inner ring convex is arranged in the middle of the inner wall of the pipe fitting, and two first annular limiting grooves and a second annular limiting groove are symmetrically arranged on the inner wall of the pipe fitting, and both ends of the pipe fitting are provided with a platform convex edge, and the inner diameter of the platform convex edge is smaller than the inner diameter of the pipe fitting;

[0009] A large surrounding rubber ring, wherein the outer wall of the large surrounding rubber ring is provided with a first annular limiting convex ring and a second annular limiting convex ring, the inner wall of the large surrounding rubber ring is provided with an inverted V ring, a sealing ring and an annular flat stopper, and a telescopic ring is formed at one end of the large surrounding rubber ring close to the annular flat stopper;

[0010] The pipe, one end of which is inserted into the large surrounding rubber ring, the end edge of the pipe contacts the annular flat block to form a first leak-proof function, the annular flat block is the first line of protection, which effectively blocks water from entering the joint surface between the pipe and the large surrounding rubber ring, and the inner diameter of the flat block is 1mm smaller than the inner diameter of the pipe.

[0011] The outer wall of the pipe cooperates with the sealing ring to form a second leak-proof function. The sealing ring is the second line of protection. Experiments have shown that when the water flow generates a full pipe pressure of 0.05Mpa, water enters the joint surface between the rubber ring and the pipe through the annular flat baffle. At this time, the protection of the sealing ring effectively enhances the pressure-bearing capacity and effectively blocks water from entering the second half of the sealing ring, achieving a good blocking and leak-proof effect.

[0012] The outer wall of the pipe cooperates with the inverted V-ring to form a third leak-proof structure. The inverted V-ring is the third line of protection. When the water flow pressure is greater than the sealing pressure of the annular flat baffle and the sealing ring, through the inverted V-shaped design, the greater the water pressure, the tighter the inverted V-ring fits the pipe, further improving the sealing performance of the large surround rubber ring and pipe fittings.

[0013] The large surrounding rubber ring is placed in the pipe fitting, and the first annular limiting protrusion cooperates with the first annular limiting groove to form a fourth leak-proof feature. The first annular limiting protrusion is the fourth line of protection to prevent water from entering the joint surface between the large surrounding rubber ring and the inner wall of the pipe fitting when the water flow generates a full pipe pressure of 0.2Mpa.

[0014] The second annular limiting protrusion cooperates with the second annular limiting groove to form the fifth leak-proof function. The second annular limiting protrusion is the fifth line of protection, further preventing water from leaking to the outside from the joint surface between the large surrounding rubber ring and the inner wall of the pipe fitting.

[0015] One end of the expansion ring of the large surrounding rubber ring contacts the inner ring convexity of the pipe fitting to form a sixth leak-proof function. The expansion height of the expansion ring is 2% to 5% of the pipe diameter. When the pipe of the pipe expands and contracts due to alternating temperatures, the expansion ring automatically compensates to ensure the anti-detachment and anti-leakage performance of the assembly.

[0016] This assembly consists of pipes, pipe fittings, and large surrounding rubber rings. The large surrounding rubber rings and pipe fittings are formed by one-time integral injection molding. The pipes are inserted into the integrally formed pressure-bearing pipe fittings. When the pipe is fully drained, the large surrounding rubber rings are used to prevent water leakage to ensure that the interface of the assembly does not leak and produce a pressure bearing capacity of not less than 0.6Mpa. At the same time, there is a telescopic ring. When the pipe of the pipe expands and contracts when the temperature alternates between hot and cold, the telescopic ring automatically compensates to ensure the anti-detachment and anti-leakage performance of the assembly.

[0017] Furthermore, the inner diameter of the convex edge of the pipe fitting is slightly smaller than the outer diameter of the pipe, and a matching cavity for accommodating two large surrounding rubber rings is separated in the pipe fitting by an inner ring convex in the middle.

[0018] Furthermore, the inner diameter of the convex edge of the pipe fitting is smaller than the outer diameter of the large surrounding rubber ring, and the angle between the inverted V-ring and the inner wall of the large surrounding rubber ring is in the range of 30° to 60°.

[0019] Furthermore, the inner diameter of the annular flat stop is 1 mm smaller than the inner diameter of the tube.

[0020] Furthermore, one end of the telescopic ring of the large surrounding rubber ring abuts against the inner ring convexity of the pipe fitting to form a sixth leak-proof function, and the telescopic height of the telescopic ring is 2% to 5% of the pipe diameter.

[0021] Furthermore, the inner diameter of the inner annular convexity is equal to the inner diameter of the tube.

[0022] Furthermore, when the water flow pressure in the pipe is greater than the sealing pressure of the annular flat baffle and the sealing ring, the inverted V-ring fits tightly against the pipe.

[0023] Furthermore, the pressure bearing capacity of the large surrounding rubber ring in the pipe is not less than 0.6 MPa.

[0024] Furthermore, when the water flow in the pipe generates a full pipe pressure of 0.05Mpa, water enters the joint surface between the large surrounding rubber ring and the pipe through the annular flat baffle, and the sealing ring enhances the pressure bearing capacity of the large surrounding rubber ring and blocks water from entering the rear half of the sealing ring.

[0025] Furthermore, the protrusion height of the sealing ring is between 0.3 mm and 0.6 mm.

[0026] (III) Beneficial effects

[0027] The building drainage assembly with a pressure-resistant structure provided by the present invention has the following beneficial effects compared with the prior art:

[0028] 1. In the pipe of the present invention, one end of the pipe is inserted into the large surrounding rubber ring, and the end edge of the pipe contacts the annular flat block to form the first leak-proof function. The annular flat block is the first line of protection, which effectively blocks water from entering the joint surface of the pipe and the large surrounding rubber ring. The inner diameter of the flat block is 1mm smaller than the inner diameter of the pipe. The outer wall of the pipe cooperates with the sealing ring to form the second leak-proof function. The sealing ring is the second line of protection. Experiments have shown that when the water flow generates a full pipe pressure of 0.05Mpa, water enters the joint surface of the rubber ring and the pipe through the annular flat block. At this time, the protection of the sealing ring effectively enhances the pressure-bearing capacity and effectively blocks water from entering the second half of the sealing ring, thereby achieving a good blocking and leak-proof effect.

[0029] 2. The outer wall of the pipe of the present invention cooperates with the inverted V-ring to form a third leak-proof feature, and the inverted V-ring is the third line of protection. When the water flow pressure is greater than the sealing pressure of the annular flat baffle and the sealing ring, through the inverted V-shaped design, the greater the water pressure, the tighter the inverted V-ring fits the pipe, further improving the sealing performance of the large surrounding rubber ring and the pipe fitting; the large surrounding rubber ring is placed in the pipe fitting, and the first annular limiting convex ring cooperates with the first annular limiting groove to form a fourth leak-proof feature. The first annular limiting convex ring is the fourth line of protection to prevent water from entering the joint surface between the large surrounding rubber ring and the inner wall of the pipe fitting when the water flow generates a full pipe pressure of 0.2Mpa.

[0030] 3. The second annular limiting convex ring cooperates with the second annular limiting groove to form the fifth leak-proof feature. The second annular limiting convex ring is the fifth line of protection, which further prevents water from leaking to the outside from the joint surface between the large surrounding rubber ring and the inner wall of the pipe fitting; one end of the expansion ring of the large surrounding rubber ring contacts the inner convex ring of the pipe fitting to form the sixth leak-proof feature. The expansion height of the expansion ring is 2% to 5% of the pipe diameter. When the pipe expands and contracts due to alternating temperatures, the expansion ring automatically compensates to ensure the anti-detachment and anti-leakage performance of the assembly.

[0031] 4. The components of the present invention are composed of pipes, pipe fittings, and large surrounding rubber rings. The large surrounding rubber rings and pipe fittings are formed by one-time integral injection molding. The pipes are inserted into the integrally formed pressure-bearing pipe fittings. When the pipe is fully drained, the large surrounding rubber rings are used to prevent water leakage to ensure that the interface of the assembly is leak-proof and produces a pressure bearing capacity of not less than 0.6Mpa. At the same time, a telescopic ring is provided. When the pipe of the pipe expands and contracts when the temperature alternates between hot and cold, the telescopic ring automatically compensates to ensure the anti-detachment and anti-leakage performance of the assembly. The connection method of the present invention has stronger pressure bearing capacity, a static pressure of 0.6Mpa, good anti-detachment ability, high construction efficiency, and low cost.

The expansion height of the expansion ring 306 is 2% to 5% of the diameter of the pipe 2. When the pipe 2 expands and contracts due to alternating temperatures, the expansion ring 306 automatically compensates to ensure the anti-detachment and anti-leakage performance of the assembly.

[0058] See also Figures 2 to 7 The inner diameter of the platform convex edge 104 of the pipe fitting 1 is slightly smaller than the outer diameter of the pipe 2.

The angle between the inverted V ring 303 and the inner wall of the large surrounding rubber ring 3 is in the range of 30° to 60°. The inner diameter of the annular flat stop 305 is 1 mm smaller than the inner diameter of the pipe 2. One end of the telescopic ring 306 of the large surrounding rubber ring 3 contacts the inner ring convex 101 of the pipe fitting 1 to form the sixth leak-proof.

When the water flow in the pipe 2 generates a full pipe pressure of 0.05Mpa, water enters the joint surface of the large surrounding rubber ring 3 and the pipe 2 through the annular flat baffle 305. The sealing ring 304 enhances the pressure-bearing capacity of the large surrounding rubber ring 3 and blocks water from entering the rear half of the sealing ring 304. The protrusion height of the sealing ring 304 is between 0.3mm and 0.6mm.

[0060] This assembly is composed of a pipe 2, a pipe fitting 1, and a large surrounding rubber ring 3. The large surrounding rubber ring 3 and the pipe fitting 1 are formed by one-time integral injection molding; the pipe 2 is inserted into the integrally formed pressure-bearing pipe fitting 1. When the pipe is fully drained, the large surrounding rubber ring 3 performs 6 water-leakage protections to ensure that the interface of the assembly does not leak and produces a pressure-bearing capacity of not less than 0.6Mpa.
