Description

Technical Field

[0001] This utility model relates to the field of quicklime screening technology, specifically a transparent clamp-type high-seal PVC elbow. Background Technology

[0002] PVC elbows are used for 90° connection of two pipe sections. Currently, PVC elbows are all integrally molded and non-transparent. During installation, it is usually necessary to heat-fuse the ends of the two pipes and then insert them into the inlet and outlet of the PVC elbow, making each connection relatively troublesome. Moreover, after connection, pipe blockage is usually at the elbow. Using existing PVC elbows not only makes it impossible to visually see if the PVC elbow is blocked, but also makes it impossible to remove the pipe from the elbow during maintenance; it can only be cut off directly.

[0003] Therefore, in order to correct the above-mentioned defects, we propose a transparent clamp-type high-seal PVC elbow. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a transparent, clamp-type, high-seal PVC elbow.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a transparent clamp-type high-seal PVC elbow, comprising a bend made of transparent material, the bend consisting of an upper half and a lower half, which are locked together by a connecting plate and bolts. The connecting plate includes an upper plate on both sides of the upper half and a lower plate on both sides of the lower half, the bolts passing through the upper plate and into the lower plate, and nuts corresponding to the bolts being provided in the lower plate.

[0006] Furthermore, the inlet of the bent pipe is a flared inlet, and the outlet is a flared outlet, both of which are fitted with rubber rings.

[0007] Furthermore, annular grooves are formed on the inner walls of the flared inlet and flared outlet, respectively, at the joints between the flared inlet and flared outlet and the bend, and rubber rings are embedded in the annular grooves.

[0008] Furthermore, the upper plate and the lower plate are provided with grooves on their opposite surfaces, and rubber strips are embedded in the grooves.

[0009] Furthermore, the rubber strip protrudes from the surface where it is mounted.

[0010] Furthermore, the rubber strips distributed vertically are staggered.

[0011] Furthermore, the inner walls of both the flared inlet and the flared outlet are provided with a frosted ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the utility model uses transparent materials and the elbow part adopts an upper and lower combination method. When the pipe body and the elbow are connected, there is no need to use a hot melt equipment for connection. The two pipe sections can be clamped by simply assembling and connecting the elbow itself. Moreover, when disassembling later, there is no need to cut the pipe body. At the same time, when the pipeline is blocked, the blockage condition inside the elbow can be seen intuitively.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a technical solution:

[0025] Please see Figure 1-8A transparent clamp-type high-seal PVC elbow includes a bend 1 made of transparent material. The bend 1 is composed of an upper half 11 and a lower half 12. The upper half 11 and the lower half 12 are locked together by a connecting plate 2 and bolts 3. The connecting plate 2 and the bend 1 are integrally extruded. The connecting plate 2 includes an upper plate 21 on both sides of the upper half 11 and a lower plate 22 on both sides of the lower half 12. The bolts 3 pass through the upper plate 21 and into the lower plate 22. The lower plate 22 is provided with nuts corresponding to the bolts 3, that is, the holes through which the upper bolts 3 pass in the upper plate 21, and the nuts in the lower plate 22 are embedded.

[0026] When connecting the two pipe sections, simply loosen the upper pipe 11 and the lower pipe 12, then insert the ends of the two pipe sections into the inlet and outlet of the bend 1 respectively, and tighten the bolts 3 to lock the upper pipe 11 and the lower pipe 12 together. In this way, the bend is connected between the two pipe sections.

[0027] To ensure airtightness, the inlet of the bend 1 is a flared inlet and the outlet is a flared outlet. Both the flared inlet and the flared outlet are inlaid with rubber rings 4. The opposite surfaces of the upper plate 21 and the lower plate 22 are provided with grooves 7, and rubber strips 6 are inlaid in the grooves 7. In this way, sealing rubber is provided at the joint to prevent liquid from seeping out from the joint.

[0028] In the above, annular grooves 5 are provided on the inner walls of the flared inlet and flared outlet. The annular grooves 5 are respectively located at the joints between the flared inlet and flared outlet and the bend 1. The rubber ring 4 is embedded in the annular groove 5, that is, after the pipe is inserted, the front end and edge of the pipe can contact the rubber ring 4, thereby improving the sealing performance.

[0029] Furthermore, the rubber strip 6 protrudes from the surface where it is installed to ensure full contact, and the staggered arrangement of the upper and lower rubber strips 6 can form two sealing lines.

[0030] In addition, the inner walls of both the flared inlet and the flared outlet are provided with a ring of frosted sand 8. The frosted sand 8 consists of countless tiny particles, which actually sand the inner walls of the flared inlet and the flared outlet. After the pipe is inserted, the frosted sand 8 comes into contact with the outer wall of the pipe port, increasing resistance and preventing the two from falling off.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
