This double protection significantly reduces the risk of leakage.

Description

Technical Field

[0001] This utility model relates to the field of PVC pipe sealing technology, specifically a quick-sealing head for segmented pressure testing. Background Technology

[0002] PVC pipes are commonly used for farmland irrigation due to their resistance to aging and agrochemical corrosion, pressure adaptability, and controllable cost. PVC material also boasts excellent chemical stability, resisting the erosion of common farmland fertilizer and pesticide residues and saline-alkali soils. It avoids the rust problems associated with metal pipes, resulting in a long service life. Furthermore, PVC pipes are lightweight, allowing for manual handling. The use of socket-type adhesive joints or elastic sealing rings for connection ensures high construction efficiency. However, when PVC pipes are not immediately connected after cutting, need to be isolated during maintenance, or require sealing during pressure testing, quick-sealing heads are needed to seal the openings and prevent leaks. This allows for temporary closure or emergency repair of the PVC pipe system. However, existing quick-sealing heads cannot seal the openings effectively, and after repeated use, the seal weakens, making them inconvenient to use. Utility Model Content

[0003] The purpose of this invention is to provide a quick-sealing head for segmented pressure testing, in order to solve the problems mentioned in the background art, such as the inability to seal the opening, the weakening of the seal on the air tube after repeated use, and the inconvenience of use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a quick-sealing head for segmented pressure testing, comprising a mounting block, wherein a connecting block is fixedly connected to one side surface of the mounting block, and a handle is connected to the surface of the mounting block;

[0005] A sealing block is connected to one side surface of the connecting block. An air tube is embedded inside the handle, and a valve is installed inside the air tube. An airbag is connected to the surface of the sealing block, and a base plate is connected to the end of the sealing block. The base plate is installed at the bottom of the airbag.

[0006] Preferably, the surface of the mounting block is provided with a sealing structure, and the sealing structure includes: an airbag one connected to one side surface of the mounting block, and an air tube two symmetrically connected to the surface of the air tube one.

[0007] Using the above technical solution, one end of the connecting block is inserted into the interior of the PVC pipe, and the entire device is moved by the handle.

[0008] Preferably, the surface of the handle is continuously provided with protrusions, and the valve is located on the outside of the handle. The connecting block and the handle are symmetrically installed on both sides of the mounting block, and the airbag is located on the outside of the connecting block.

[0009] By adopting the above technical solution, the protrusions on the handle surface can increase friction and enhance the connection of the handle.

[0010] Preferably, the sealing block has a tapered cross-section, and the outer side of the sealing block is made of silicone material, with an airbag disposed on the outer side of the sealing block.

[0011] Using the above technical solution, one end of the sealing block is inserted into the PVC pipe, so that its outer side fits against the inner wall of the PVC pipe, thus fixing the overall position.

[0012] Preferably, the first air tube passes through the interior of the mounting block and the connecting block, and the first air tube passes through the bottom of the sealing block and connects to the second airbag, which is disposed between the sealing block and the bottom plate.

[0013] Using the above technical solution, gas is delivered into the airbag through the trachea to inflate the airbag.

[0014] Preferably, the airbag is configured as a hollow cylindrical structure and is mounted on one side of the mounting block.

[0015] Using the above technical solution, once the airbag inflates, the connection between the broken PVC pipe and the installation block is sealed.

[0016] Preferably, the second trachea penetrates the interior of the connecting block, and the end of the second trachea is connected to the surface of the first airbag.

[0017] Using the above technical solution, the gas inside the first trachea enters the second trachea, and the gas enters the airbag through the second trachea, causing the first airbag to inflate.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the rapid sealing head for segmented pressure testing:

[0019] 1. Airbag 1 and Airbag 2 are set up for double sealing. Gas is supplied to the inside of Airbag 2 through Air Tube 1 at the same time, so that Airbag 2 expands and fits tightly against the inner wall of Air Tube 1 to form the main seal. At the same time, gas enters Airbag 1, and Airbag 1 expands at the mounting block and the port of Air Tube 1 to form an auxiliary seal. The double protection greatly reduces the risk of leakage.

[0020] 2. It is equipped with a sealing block, airbag one and airbag two. The sealing block adopts a conical silicone structure. The conical shape makes it easier to insert into the PVC pipe. The silicone material can be adapted to PVC pipes with different inner wall smoothness. Since airbag one and airbag two are inflatable structures, they can be reused. After repeated inflation and deflation, they can still maintain good deformation ability. By deflating them, they can be quickly removed. Attached Figure Description

[0028] 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.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a quick-sealing head for segmented pressure testing, including an installation block 10, a connecting block 20, a handle 30, a sealing block 40, an air pipe 50, a valve 501, an air bladder 502, an air bladder 503, a base plate 504, and an air pipe 505.

[0030] This quick-sealing head enhances the overall sealing performance of the device during use. The specific implementation method is as follows:

[0031] A connecting block 20 is fixedly connected to one side surface of the mounting block 10, and a handle 30 is connected to the surface of the mounting block 10. A sealing block 40 is connected to one side surface of the connecting block 20. An air tube 50 is embedded inside the handle 30, and a valve 501 is installed inside the air tube 50. An airbag 503 is connected to the surface of the sealing block 40, and a base plate 504 is connected to the end of the sealing block 40. The base plate 504 is installed at the bottom of the airbag 503. A sealing structure is provided on the surface of the mounting block 10, and the sealing structure includes: an airbag 502 connected to one side surface of the mounting block 10, and the air tube 50 symmetrically connected to... The device includes a second air tube 505, a handle 30 with continuous protrusions on its surface, a valve 501 on the outside of the handle 30, a connecting block 20 and the handle 30 symmetrically mounted on both sides of the mounting block 10, an airbag 502 on the outside of the connecting block 20, a sealing block 40 with a conical cross-section and a silicone outer surface, an airbag 502 on the outside of the sealing block 40, an air tube 50 penetrating the interior of the mounting block 10 and the connecting block 20, and penetrating the bottom of the sealing block 40 to connect with an airbag 503, which is positioned between the sealing block 40 and the base plate 504. An airbag 502 is a hollow cylindrical structure mounted on one side of the mounting block 10, and an air tube 505 penetrating the interior of the connecting block 20, with its end connected to the surface of the airbag 502.

[0032] Holding the handle 30, the user moves the mounting block 10, which in turn moves the connecting block 20, causing one side of the connecting block 20 to move to the side of the PVC pipe. At this time, the user holds the surface of the handle 30 and applies a pushing force to the handle 30, which pushes the mounting block 10 and the connecting block 20 to move. This causes the connecting block 20 to move the sealing block 40 to align with the PVC pipe port to be sealed, and pushes the entire device along the PVC pipe. At this time, the connecting block 20 moves the airbag 503 and the base plate 504 into the interior of the PVC pipe. Since the sealing block 40 has a conical structure, the tip of the sealing block 40 enters the PVC pipe first, and the conical surface guides the sealing block 40 to smoothly insert into the interior of the PVC pipe until the outer silicone of the sealing block 40 initially adheres to the inner wall of the PVC pipe. At this time, the outer silicone of the sealing block 40 temporarily positions the entire device.

[0033] At this time, the end of airbag 502 corresponds to the PVC pipe port. Then, connect the end of the inflatable structure to the end of air tube 50, open valve 501, and let air into the device through air tube 50. At the same time, the air in air tube 50 enters the interior of airbag 503, causing airbag 503 to inflate. At this time, airbag 503 expands outward due to the obstruction of the base plate 504, so that the outer surface of airbag 503 fits against the inner wall of the PVC pipe, tightly filling the gap between the mounting block 10 and the PVC pipe port. The air enters the interior of air tube 505 through air tube 50, and the air enters the interior of airbag 502 through air tube 505, causing airbag 502 to inflate. At this time, airbag 502 inflates between the mounting block 10 and the PVC pipe port, which can seal the two and form a double seal. Then close valve 501.

[0034] After the device is used, valve 501 can be opened. At this time, the blockage of air pipe 50 disappears, and the gas inside airbag 502 and airbag 503 is discharged simultaneously. At this time, airbag 502 and airbag 503 contract, so that the surfaces of airbag 502 and airbag 503 lose contact with the PVC pipe, and the seal on the PVC pipe disappears. Pull the handle 30 outward, and the handle 30 will move the mounting block 10. The mounting block 10 will move the sealing block 40 through the connecting block 20, so that the sealing block 40 can be pulled out from the PVC surface, and the entire device can be removed.

[0035] Working principle: When using this segmented pressure testing quick sealing head, airbag 1 502, airbag 2 503, base plate 504 and air pipe 2 505 are set up to enhance the overall sealing performance of the device and increase its overall practicality.

[0036] 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.
