Specifically, the tube body 1 and the inner tube body 2 are respectively integrally formed by engineering plastics, or metal tubes, such as stainless steel tubes, are respectively formed by machining, or plastic-clad metal tubes can be formed by machining.
The tubular body 1 may be constructed as a rectangular tube, a circular tube, or a profile tube having a defined shape, such as a hexagonal tube. One end of the tube body 1 is closed, and the other end is provided with a hole. The closed end is the first end 1.1 and the open end is the second end 1.2. The holes on the second end 1.2 are communication holes, and the pipe body 1 is provided with flow channels communicated with the communication holes in the pipe body 1 through the communication holes. And a water inlet hole is formed in the side wall of the pipe body 1.
When the inner pipe body 2 is not assembled, the flow passage communicates the water inlet hole and the communication hole. And the flow passage at least comprises a first flow passage 1.3 with a circular section, namely the section of the flow passage in the pipe body 1 is not limited to be consistent with the shape of the pipe body 1. The first flow channel 1.3 is constructed and arranged to fit the inner tube 2. Therefore, the section of the portion of the flow passage communicating with the water inlet hole, that is, the portion other than the first flow passage 1.3 may be configured to be circular or elliptical with a defined shape. The partial flow channels may also be straight flow channels or flow channels having a defined meandering shape, for example in a sinusoidal configuration.
In some embodiments, fig. 1 shows an embodiment of the tubular body 1, i.e. the tubular body 1 is configured as a circular tube, and the outer and inner cross-sections thereof are circular. The inner flow passage only comprises a first flow passage 1.3 with a circular section, and at the moment, the cavity inside the pipe body 1 is the first flow passage 1.3. The side wall of the pipe body 1 is provided with a water inlet hole which runs through the side wall of the pipe body 1 and is communicated with the flow channel. Meanwhile, a water inlet pipe 3 is fixedly connected to the side wall of the pipe body 1 through an integrally formed structure or welding or thermoplastic or other equivalent means, and the water inlet pipe 3 is communicated with a water inlet hole and used for guiding water in an irrigation system into the pipe body 1.
The inner pipe body 2 is arranged in a flow channel inside the pipe body 1, one end of the inner pipe body 2 is connected with the pipe body 1, and the other end of the inner pipe body 2 extends into the pipe body 1 along the axial direction of the pipe body 1 and keeps a suspended state. Specifically, the inner pipe 2 extends into or out of the pipe 1 from the communication hole. Wherein, the end of the inner tube body 2 connected with the tube body 1 is a connecting part 2.1, and the suspended end is a reducing tube 2.2. A second flow passage for the co-water flowing out of the connection pipe is also formed inside the inner pipe body 2.
The axis of the reducer 2.2 is collinear with the axis of the first flow passage 1.3, i.e. remains at least partially coaxially arranged with the body 1. The reducing pipe 2.2 is here preferably a concentric reducing pipe 2.2.
The large head 2.2.2 of the reducing pipe 2.2 faces the end face of the first end 1.1, a gap exists between the large head 2.2.2 and the end face of the first end 1.1, and the reducing pipe 2.2 is also communicated with the flow passage through the large head 2.2.2 and the gap. The reducing pipe 2.2 is fixedly connected with the connecting part 2.1 through the small head part 2.2.1 and penetrates through the connecting part 2.1. It will be readily appreciated that the reducer 2.2 will enter through the inlet opening through the small head 2.2.1 and that water flowing through the flow channel, the gap, and the large head 2.2.2 will be directed out of the body 1 to the next stage in the irrigation system, for example, the sprinkler system.
Specifically, the connecting portion 2.1 may be in the form of a nut, a sleeve, an insert nut, or the like.
In some embodiments, the outer side wall of the second end 1.2 of the pipe body 1 is threaded, the connecting portion 2.1 is in the form of a sleeve, the inner side wall of the sleeve is externally threaded, and the connecting portion 2.1 is screwed to the pipe body 1 through the threads. The end face of the sleeve is provided with a mounting hole communicated with the communicating hole, and the small head part 2.2.1 is fixed in the mounting hole by welding, so that the reducing pipe 2.2 is fixed on the connecting part 2.1, and the inner pipe body 2 is also detachably fixed on the pipe body 1.
In some embodiments, as shown in fig. 2, the side wall of the communicating hole of the tube body 1 is internally threaded, the connecting portion 2.1 is in the form of an internal and external threaded nut, the external side wall thereof is externally threaded, and the connecting portion 2.1 is screwed into the communicating hole of the tube body 1 by the above-mentioned threads. Preferably, the end surface of the connecting part 2.1 close to the outside is flush with the end surface of the second end 1.2 of the pipe body 1, so as to keep the integral structure and appearance of the whole connecting pipe compact. The connecting part 2.1 is provided with a mounting hole penetrating through the connecting part 2.1, and the small head part 2.2.1 is fixed in the mounting by welding, so that the reducing pipe 2.2 is fixed on the connecting part 2.1.
In some embodiments, the small head 2.2.1 may also be fixed to the connection portion 2.1 by snapping, plugging, snapping or thermoplastic or other equivalent means.
In some embodiments, as shown in fig. 1 and 3, the connecting part 2.1 is fixed with the water outlet pipe 4, the water outlet pipe 4 is fixed on the connecting part 2.1 by welding or bonding or thermoplastic or other equivalent methods, and the axis of the water outlet pipe 4 is collinear with the axis of the small head part 2.2.1. The external structure of the water outlet pipe 4 can be processed into a cylindrical shape, a hexagonal prism shape, a quadrangular prism shape and the like, so that when the water outlet pipe 4 is installed, the connecting part 2.1 can be screwed in and out by operating the water outlet pipe 4 through a wrench, and the detachable fixation of the inner pipe body 2 and the pipe body 1 is realized.
Specifically, a filter screen 2.3 is fixed on the radial inner side of the large end part 2.2.2 of the reducing pipe 2.2, and the filter screen 2.3 is used for filtering water flow flowing through the reducing pipe 2.2 and intercepting impurities such as sand and stone. Alternatively, the filter screen 2.3 may be fixed directly to the large head 2.2.2 by means of a clamp.
In addition, when filter screen 2.3 is directly installed on inner pipe 2, because inner pipe 2 is connected with the water pipe in the irrigation system, the quality is heavier, and the workman is difficult to take up inner pipe 2. Particularly, in a mountain area or a hilly area, after the inner pipe body 2 is taken down from the pipe body 1, the inner pipe body 2 and the water pipe connected with the inner pipe body slide down along a mountain slope or a step under the action of gravity, which is not beneficial for workers to hold the inner pipe body 2 to perform fine operations such as replacing the filter screen 2.3, and the accident that the filter screen 2.3 is damaged may occur. In order to facilitate the disassembly and assembly of the filter screen 2.3, a fixing sleeve 5 can be additionally arranged, the fixing sleeve 5 is connected with the large end part 2.2.2 through embedding, clamping or screwing or other equivalent modes, and then the filter screen 2.3 is installed on the fixing sleeve 5. Therefore, when replacing the filter screen 2.3, a worker can simply take the fixing sleeve 5 off the large head part 2.2.2 through a tool and carefully replace the filter screen 2.3 on the fixing sleeve 5 without being influenced by a real-time operation environment. The fixing sleeve 5 can also be used as a spare part matched with the filter screen 2.3, and the fixing sleeve 5 and the filter screen 2.3 are replaced together during replacement.
As shown in fig. 2, after the inner pipe 2 extends into the pipe 1 from the communication hole and is fixed, a reducing annular cavity is formed between the inner pipe 2 and the first flow channel 1.3 of the pipe 1. In the small head 2.2.1 section, the flow area of the annular cavity is the largest. Along the axial direction of the reducing pipe 2.2, the flow area of the annular cavity is gradually reduced from the small head part 2.2.1 side to the large head part 2.2.2 side. Therefore, after the water flows from the water inlet pipe 3, at least part of the water moves in the annular cavity in the form of rotational flow and rotates in the annular cavity, and impurities such as sand and stones in the water flow are gathered on the side wall of the first flow passage 1.3 under the action of centrifugal force and are far away from the filter screen 2.3. Thereby prolonging the service life of the filter screen 2.3.
When the filter screen 2.3 is replaced, impurities such as sand and stones accumulated in the first flow passage 1.3 can be cleaned out by cleaning the first flow passage 1.3 at the same time.
In some embodiments, the water inlet hole comprises a water inlet section, and the water inlet section tangentially leads into the first flow channel 1.3, so that most of water makes rotational flow motion in the first flow channel 1.3, and the probability that impurities such as sand and the like stay in the first flow channel 1.3 after making centrifugal motion is increased. Preferably, the axis of the water inlet section is perpendicular to the axis of the reducing pipe 2.2.
Specifically, the water inlet section is arranged corresponding to the small head 2.2.1, and water firstly rotates around the small head 2.2.1 after entering the first flow channel 1.3 and then rotates towards the large head 2.2.2 along the axial direction of the reducing pipe 2.2. So that water can fully swirl after entering the first flow channel 1.3, and impurities such as sand and stones can be effectively separated.
In some embodiments, the tubular body 1 is arranged vertically. Compared with the pipe body 1 which is horizontally arranged, the cyclone motion in the first flow channel 1.3 in the pipe body 1 which is vertically arranged is more sufficient, and the separation effect of sand, stone, impurities and the like is better. Meanwhile, the vertically arranged tube body 1 is also convenient for impurities separated by centrifugal motion to settle and accumulate at the bottom of the tube body 1.
In some embodiments, as shown in fig. 2, in order to facilitate the collection of separated sand, the inner end surface of the first end 1.1 is provided with a settling groove 1.4. Alternatively, the deposition bath 1.4 is a tapered hole. Alternatively, the deposition groove 1.4 may be configured as a plurality of grooves formed in the end surface of the first end 1.1.
In a specific embodiment, the working principle is as follows:
the anti-blocking connecting pipe is constructed by two pipes sleeved inside and outside, one of the pipes is a pipe body 1, the pipe body 1 is constructed by a round pipe with one closed end, the other end of the round pipe is provided with a hole, an internal thread is constructed on the hole, the hole is a communicating hole, a flow channel which is round in section and communicated with the communicating hole is arranged in the pipe, and the flow channel is a first flow channel 1.3. The second is an inner pipe body 2 sleeved inside the pipe body 1, and the inner pipe body 2 includes a connecting portion 2.1 for connecting with the pipe body 1, a reducing pipe 2.2 with a variable outer diameter, and a filter screen 2.3 fixed on the radial inner side of the large end portion side of the reducing pipe 2.2.2. The filter screen 2.3 is mounted by means of a fixing sleeve 5. The pipe body 1 and the inner pipe body 2 are both vertically arranged. The position of the outer side wall of the pipe body 1 corresponding to the small head is provided with a water inlet hole, and the water inlet hole tangentially leads into the first flow channel 1.3.
So that a reducing annular cavity is formed between the outer side wall of the inner pipe body 2 and the inner wall of the first flow channel 1.3 of the pipe body 1. In the small head section, the flow area of the annular cavity is largest. The flow area of the annular cavity decreases gradually in the axial direction of the reducing pipe 2.2 from the small head side to the large head side. Therefore, after water enters from the water inlet hole tangentially, at least one part of water moves in the annular cavity in a rotational flow mode and drives other water to rotate in the annular cavity, and impurities such as sand and stones in the water flow are gathered on the side wall of the first flow channel under the action of centrifugal force and far away from the filter screen in the end part of the large head part on the axis of the first flow channel. Thereby prolonging the service life of the filter screen 2.3. And water flows into the reducing pipe 2.2 from a gap between the large head part and the end surface of the first end, and finally flows out of the connecting pipe from the small head part fixed on the connecting part 2.1. Alternatively, impurities such as sand and sand left over are deposited in the deposition tank 1.4.
When the filter screen 2.3 is replaced, the fixing sleeve 5 and the filter screen 2.3 are replaced together. Compared with the prior art, the replacement is more convenient and faster.
