Description

Technical Field

[0001] The utility model relates to the technical field of elbows, in particular to an anti-clogging wear-resistant elbow. Background Art

[0002] An elbow is a pipe connector that is usually used to change the direction of a pipe. It consists of a curved pipe that allows the fluid to change its flow direction. Elbows are widely used in pipe systems in industrial, construction and civil fields to transport various liquids, gases and solid particles. In existing pipe systems, most blockage accidents occur at elbows, which require disassembly and cleaning after blockage, which is very troublesome and is not suitable for elbows connected to other pipes by welding.

[0003] The application number 201721684033.8 disclosed a kind of anti-blocking elbow, including an elbow, an opening is provided at the bend of the elbow, a dredging piece is fixedly connected to the opening of the elbow, the dredging piece includes a dredging pipe fixedly connected to the outside of the elbow, a dredging rod is provided in the inner cavity of the dredging pipe, a push-pull handle is fixedly connected to the end of the dredging rod away from the elbow, a sealing groove is cut in the inner wall of the dredging pipe, and a sealing ring that is tightly attached to the dredging rod is interference-connected to the sealing groove. When a blockage accumulates at the bend of the elbow, the push-pull handle is pushed toward the elbow so that the dredging rod can be extended into the inner cavity of the elbow, and the blockage is squeezed and dispersed under the reciprocating pulling and flows away with the fluid. During the whole process of clearing the blockage, the sealing ring is always squeezed with the dredging rod, so that the fluid cannot leak from the opening. The utility model has the advantages of being able to easily clear the blockage in the inner cavity of the elbow without affecting the fluid transportation. However, the document needs to be repeatedly disassembled and assembled when used, which is inconvenient to operate and thus affects work efficiency. Therefore, in view of this, the existing structure and defects are studied and improved, and an anti-clogging wear-resistant elbow is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-clogging wear-resistant elbow to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wear-resistant elbow with anti-clogging, comprising an elbow, a branch pipe is provided at the turning point of the elbow, a clearing rod slides in the branch pipe, a pull ring is provided at the end of the clearing rod away from the elbow, a rubber block is provided at the end of the clearing rod close to the elbow, one end of the branch pipe is threadedly connected with a threaded sleeve, the threaded sleeve restricts the clearing rod inside the slide, and a protective shell is clamped at the other end of the threaded sleeve.

[0006] Preferably, spiral patterns are provided at the inlet and outlet of the internal pipe of the elbow.

[0007] Preferably, a wear-resistant block is fixed to the front end of the branch pipeline on the inner wall of the elbow, and the wear-resistant block is arc-shaped.

[0008] Preferably, a layer of sound insulation sponge is provided on the outside of the elbow.

[0009] Preferably, the interior of the elbow is coated with a wear-resistant coating.

[0010] Preferably, the elbow is made entirely of cast steel.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. If the utility model needs to clear the blockage, after removing the protective shell, pull the pull ring, push the dredging rod to make the rubber block on the head leave the cavity, and pull it back and forth repeatedly to dredge. After the dredging is completed, pull the dredging rod back, the rubber block is stuck in the cavity, and at the same time, the other end of the dredging rod is stuck in one end of the threaded sleeve. After the fixation is completed, the protective shell is stuck into the threaded sleeve, which can effectively prevent the outside world from accidentally touching the dredging rod. This component has good dredging effect and is easy to operate. If the component needs to be replaced and maintained, you only need to remove the threaded sleeve from the branch pipe and pull out the dredging rod with force. The operation is simple, disassembly is easy and easy to use. The rubber block on the head has high elasticity, strong sealing and good joint properties.

[0013] 2. The utility model designs the inlet and outlet of the internal pipe of the elbow into a spiral pattern, which can generate eddy currents when the fluid passes through, helping to remove solid particles or sediments attached to the inner wall of the elbow, thereby effectively preventing blockage. An arc-shaped wear-resistant block is fixed at the front end of the branch pipe, which can reduce the long-term impact of the fluid on one side of the elbow, extend the service life of the elbow, and protect the dredging rod and rubber block from direct erosion.

[0020] As mentioned above, in this case, when in use, if it is necessary to clear the blockage, after removing the protective shell 204, pull the pull ring 201, push the dredging rod 2 so that the rubber block 202 on the head leaves the cavity, and pull it back and forth repeatedly to dredge. After the dredging is completed, pull the dredging rod 2 back, and the rubber block 202 is stuck in the cavity. At the same time, the other end of the dredging rod 2 is stuck in one end of the threaded sleeve 203. After the fixation is completed, the protective shell 204 is stuck into the threaded sleeve 203, which can effectively prevent the outside world from accidentally touching the dredging rod 2. This component has a good dredging effect and is easy to operate. If the component needs to be replaced and maintained, you only need to remove the threaded sleeve 203 from the branch pipe 104 and pull out the dredging rod 2 with force. The operation is simple, disassembly is easy and easy to use. The rubber block 202 is used on the head, which has high elasticity, strong sealing and good joint properties.

[0021] Spiral patterns 101 are provided at the inlet and outlet of the internal pipe of the elbow 1. A wear-resistant block 102 is fixed at the front end of the branch pipe 104 on the inner wall of the elbow 1. The wear-resistant block 102 is arc-shaped. A layer of sound insulation sponge 103 is provided on the outside of the elbow 1.

[0022] As mentioned above, the inlet and outlet of the internal pipe of the elbow 1 are designed to be a spiral pattern 101, which can generate eddy currents when the fluid passes through, helping to remove solid particles or sediments attached to the inner wall of the elbow, thereby effectively preventing blockage. An arc-shaped wear-resistant block 102 is fixed at the front end of the branch pipe 104, which can reduce the long-term impact of the fluid on one side of the elbow 1, extend the service life of the elbow 1, and protect the dredging rod 2 and the rubber block 202 from direct erosion. A layer of sound insulation sponge 103 is arranged on the outside of the elbow 1, which can achieve a good sound insulation effect.

[0023] The elbow 1 is coated with a wear-resistant coating inside, and the elbow 1 is made of cast steel as a whole.

[0024] As mentioned above, the elbow 1 is coated with a wear-resistant coating to resist the erosion of the fluid and the wear of solid particles, thereby extending the service life of the elbow 1. The steel casting has high strength and wear resistance and can meet the basic requirements of wear resistance.

[0025] Working principle: When using this case, if it is necessary to clear the blockage, remove the protective shell 204, pull the pull ring 201, push the dredging rod 2 to make the head rubber block 202 leave the cavity, and pull it back and forth repeatedly to dredge. After the dredging is completed, pull the dredging rod 2 back, the rubber block 202 is stuck in the cavity, and at the same time, the other end of the dredging rod 2 is stuck in one end of the threaded sleeve 203. After the fixation is completed, the protective shell 204 is stuck into the threaded sleeve 203, which can effectively prevent the outside world from accidentally touching the dredging rod 2. This component has a good dredging effect and is easy to operate.
