[0028] Now, the check valve that is easy to install provided by the present utility model will be described.

[0029] Please refer to Figure 1 and Figure 2 , the check valve that is easy to install includes a check valve body 1, two mounting members 2, and a fixing mechanism 3. Among them, guide pipes are provided at both ends of the check valve body 1, the two mounting members 2 are respectively arranged on the two guide pipes, an insertion pipe cavity 201 is provided on the mounting member 2, a storage bin 202 is provided in the insertion pipe cavity 201, a sealing glue is provided in the storage bin 202, and when the conduit to be installed is inserted into the storage bin 202, the sealing glue fills the space between the inner wall of the insertion pipe cavity 201 and the conduit. The fixing mechanism 3 is arranged on the mounting member 2, and when the fixing mechanism 3 is locked, the mounting member 2 is fixed to the conduit.

[0030] The beneficial effects of the check valve provided in this embodiment are as follows: Compared with the prior art, the check valve provided in this embodiment is fixed to the catheter by setting the fixing mechanism 3 and the insertion tube cavity 201 of the mounting member 2. After the catheter is inserted into the insertion tube cavity 201, the check valve body is fixed to the catheter, so that the check valve body 1 can be fixed to catheters with different diameters. At the same time, by setting the storage bin 202 and the sealant in the storage bin 202, when the catheter is inserted, the space between the catheter and the inner wall of the insertion tube cavity 201 is in a sealed state, preventing the leakage of the conveyed material in the pipeline. Further, it is convenient for the check valve of the present utility model to be installed on pipelines with different diameters. Compared with the prior art, the installation of threaded joints is reduced, and the installation convenience of the check valve is further improved.

[0031] As Figure 2 shown, the mounting member 2 includes a mounting tube 203 and a sealing tube 204. The mounting tube 203 is arranged on the material guiding tube, and the sealing tube 204 is arranged at one end of the mounting tube 203. The outer diameter of the sealing tube 204 is the same as that of the mounting tube 203, and the inner diameter of the sealing tube 204 is larger than the inner diameter of the mounting tube 203. The storage bin 202 is arranged on the side wall of the mounting tube 203, and the open end of the storage bin 202 is arranged on the end surface of the mounting tube 203 connected to the sealing tube 204. The inner cavity of the sealing tube 204 is the insertion tube cavity 201. By setting the inner diameter of the sealing tube 204 to be larger than the inner diameter of the mounting tube 203, on the one hand, it provides a setting space for the opening of the storage bin 202. When the catheter is inserted into the storage bin 202, there is a gap between the sealing tube 204 and the catheter. After the sealant fills the gap, the sealing tube 204 and the catheter are sealed.

[0032] As a preferred technical solution, a partition tube 205 is arranged in the storage bin 202. The length of the partition tube 205 is less than the length of the storage bin 202. The front end of the partition tube 205 is flush with the front end of the mounting tube 203. The partition tube 205 is arranged at intervals with both the inner wall and the outer wall of the storage bin 202, and the interval between the partition tube 205 and the inner wall of the storage bin 202 is larger than the interval between the partition tube 205 and the outer wall of the storage bin 202. A sliding plate 206 is arranged between the partition tube 205 and the inner wall of the storage bin 202, and a diaphragm 207 is arranged between the partition tube 205 and the outer wall of the storage bin 202. The diaphragm 207 is made of a fragile material. During use, the catheter first abuts against the sliding plate 206, and then the catheter continues to be inserted into the storage bin 202, which will push the sliding plate 206 to slide into the storage bin 202, and the pressure of the sealant will increase until the diaphragm 207 is squeezed and broken, and the sealant will enter the gap between the catheter and the sealing tube 204 from the gap between the partition tube 205 and the mounting tube 203.

[0033] In this embodiment, a plurality of connecting rods 208 are provided on the outer wall of the partition pipe 205, and the other ends of the connecting rods 208 are connected to the outer wall of the storage bin 202. The arrangement of the connecting rods 208 can, on the one hand, fix the partition pipe 205, and on the other hand, it will not prevent the sealant inside the partition pipe 205 from being extruded between the seal pipe 204 and the conduit through the outside of the partition pipe 205.

[0034] In this embodiment, a plurality of bumps 209 are provided on the outer wall of the installation pipe 203. The bumps 209 are evenly arranged along the circumferential direction of the installation pipe 203. The arrangement of the bumps 209 can increase the roughness of the outer wall of the installation pipe 203, facilitate the gripping of the installation pipe 203, and thus facilitate the installation of the installation pipe 203 on the feed pipe of the check valve body 1.

[0035] In addition, a fixing pipe 210 is sleeved outside the seal pipe 204. The fixing pipe 210 can move axially relative to the seal pipe 204. The fixing mechanism 3 is provided on the fixing pipe 210. The setting of the fixing pipe 210 provides an installation space for the fixing mechanism 3.

[0036] Specifically, the fixing mechanism 3 includes a plurality of fixing bolts 301 and a plurality of fixing holes. The fixing holes are provided on the fixing pipe 210 and are evenly arranged along the circumferential direction of the fixing pipe 210. The fixing bolts 301 correspond to the fixing holes one by one, and the fixing bolts 301 are screwed into the corresponding fixing holes. The bottom end of the fixing bolt 301 abuts against the conduit, so that the fixing pipe 210 is fixed relative to the conduit. The arrangement of the fixing bolts 301 and the fixing holes is simple in structure and convenient to use. At the same time, since the fixing pipe 210 is fixed on the conduit, the check valve is also fixed relative to the conduit.

[0037] As Figure 2 shown, a plurality of stabilizing blocks 302 are provided on the outer wall of the fixing pipe 210. The stabilizing blocks 302 correspond to the fixing holes one by one. The stabilizing blocks 302 are provided outside the corresponding fixing holes. The stabilizing blocks 302 are provided with stabilizing holes, and the fixing bolts 301 are screwed into the corresponding stabilizing holes and fixing holes. The arrangement of the stabilizing blocks 302 is equivalent to increasing the thickness of the fixing pipe 210, making the installation of the fixing bolts 301 more stable.

[0038] Finally, a first thread is provided on the inner wall of the installation pipe 203, and a second thread is provided on the outer wall of the feed pipe. The first thread is adapted to the second thread, and the installation pipe 203 is screwed onto the feed pipe. A third thread is provided on the outer wall of the seal pipe 204, and a fourth thread is provided on the inner wall of the fixing pipe 210. The third thread is adapted to the fourth thread, and the fixing pipe 210 is screwed onto the seal pipe 204.

[0039] During the actual installation of the check valve that is easy to install according to the present utility model, the conduit is inserted into the sealing tube 204 until the conduit abuts against the sliding plate 206. At this time, the fixing bolt 301 is rotated to fix the fixing tube 210 to the conduit. Then, the installation tube 203 is rotated to move the installation tube 203 and the sealing tube 204 towards the fixing tube 210. The conduit will push the sliding plate 206 to move into the storage bin 202, forcing the sealant to break through the diaphragm 207 and enter between the conduit and the sealing tube 204 for sealing. The connection between the installation member 2 on one side of the check valve body 1 and the conduit is completed. According to the above steps, the installation member 2 on the other side of the check valve body 1 is connected to the conduit to complete the installation.

[0040] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
