Embodiment 1

[0107] Such as Figure 4-Figure 9 As shown, the present embodiment discloses an insert, which is used in the pressure vessel 10, and the top surface of the insert 2 and the inner wall near the top surface both have female parts. The female part is various grooves opened on the insert, and the female part is used to connect with the male part on the inner liner 1 of the pressure vessel 10 . The public part is a protrusion on the inner tank layer. Both the top surface and the inner wall of the insert 2 are provided with a female portion, the inner liner layer 1 can be wrapped to the inner wall of the insert 2, and the male portion on the inner liner layer 1 can be connected to the female portion of the inner wall of the insert 2 connection, forming a tightly combined inner buckle structure, and improving the connection strength between the insert 2 and the inner liner layer 1; at the same time, the insert 2 only cooperates with the inner liner layer 1 to form the mouth structur...

Embodiment 2

[0128] Such as Figure 11As shown, the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that the fixing groove 21 also includes a second fixing groove 212, and the inner diameter of the second fixing groove 212 is from the center of the insert 2 to the center of the insert 2 The outer side gradually decreases, and the fixing flange 11 also includes a second fixing flange (not shown in the figure), and the first fixing flange is adapted to the second fixing groove 212 and embedded in the second fixing groove 212, so as to prevent the liner from The upper end of 1 slides from the center of the insert 2 to the outside, so as to avoid misalignment between the inner liner 1 and the insert 2. The number of the second fixing groove 212 and the second fixing flange are multiple, and the plurality of fixing grooves 21 are arranged at intervals along the circumferential direction of the insert 2, so that the insert 2 and the liner layer 1 are...

Embodiment 3

[0130] Such as Figure 12 As shown, the structure of this embodiment is basically the same as that of Embodiment 2, the difference is that: the number of the first fixing groove 211 and the second fixing groove 212 are multiple, the first fixing groove 211 and the second fixing groove 212 They are arranged at intervals along the circumferential direction of the insert 2 . The first fixing groove 211 prevents the upper end of the liner layer 1 from sliding from the outside to the center of the insert 2, and the second fixing groove 212 prevents the upper end of the inner liner 1 from sliding from the center to the outside of the insert 2, so that the inside The upper end of the liner layer 1 is closely connected with the upper surface of the insert 2, preventing the upper end of the liner layer 1 from sliding along the radial direction of the insert 2, and avoiding misalignment or delamination between the liner layer 1 and the insert 2.

Abstract

The invention discloses an insert, a pressure vessel and a water treatment device. An insert body is used for a pressure vessel body, the top surface of the insert body and the inner wall surface, close to the top surface, of the insert body are both provided with female parts, and the female parts are used for being connected with male parts on an inner container layer of the pressure vessel body. The pressure vessel body comprises the hollow inner container layer and the insert body, and the inner container layer wraps the outer wall face of the insert body and wraps the inner wall face of the insert body from the upper surface of the insert body. The top face and the inner wall face of the insert body are both provided with the female parts, the inner container layer can wrap the inner wall face of the insert body, so that the combination face of the insert body and the inner container layer is located inside the inner container layer, even if a small amount of water leaks along the combination face, the water can only flow into the pressure vessel and cannot leak out, and the sealing effect is improved. The male parts on the inner container layer can be connected with the female parts on the inner wall surface of the insert body to form a tightly combined inner buckle structure, so that the connection strength of the insert body and the inner container layer is improved; and meanwhile, the insert body is only matched with the inner container layer to form an opening structure of the pressure vessel, so that leakage paths are reduced, and the forming rate is high.

Description

technical field [0001] The invention relates to an insert, a pressure vessel and a water treatment device. Background technique [0002] As a necessary accessory of water treatment devices, FRP pressure vessels have the advantages of strong pressure bearing capacity, corrosion resistance, cleanliness, light weight, and low cost, so they are more and more widely used in water treatment devices. The water treatment device generally also includes a multi-way control valve used in conjunction with the glass fiber reinforced plastic pressure vessel to achieve sealing and water treatment functions. [0003] The invention patent with application number 201310296480.6 discloses a FRP pressure vessel and a water treatment device including it. The FRP pressure vessel consists of a threaded insert 1`, an inner liner layer 2`, a winding layer 3`, an adapter insert 4` and an O-ring 5` (such as figure 1 shown). The threaded insert 1' and the inner liner layer 2' are fixed by blow moldi...
