Description

Technical Field

[0001] This utility model relates to the field of ship fittings technology, and in particular to a small-diameter stainless steel pipe through-cabin fitting. Background Technology

[0002] Existing stainless steel pipe penetration fittings employ two methods: one involves directly creating hatch openings in the bulkhead or deck, inserting the stainless steel pipe directly into the opening, and welding it. This method requires precise dimensions for the hatch opening. The other method utilizes a cladding plate, with pre-machined holes on the cladding plate. During installation, the cladding plate is placed over the hatch opening on the bulkhead or deck, and its outer edge is welded to the outer wall of the bulkhead or deck. The stainless steel pipe is then inserted into the opening of the cladding plate and welded to it. This method reduces the requirements for the hatch opening dimensions. However, both methods require repeated measurements and adjustments to the angle of the stainless steel pipe within the hole to ensure perpendicularity to the bulkhead or deck. After angle adjustment, the pipe must be held in place with one hand while welding with the other, making the operation cumbersome and resulting in low installation accuracy.

[0003] Therefore, this utility model proposes a small-diameter stainless steel pipe penetration fitting to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a small-diameter stainless steel pipe through-cabin fitting that is easy to operate, can effectively ensure the verticality of the stainless steel pipe, and improve installation accuracy.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a small-diameter stainless steel pipe penetration component, which is installed on the bulkhead or deck. Its innovation lies in the fact that the penetration component includes a stainless steel pipe, a cover plate, and a support plate.

[0006] The cladding plate is welded to the bulkhead or deck. A through hole for a stainless steel pipe to pass through is opened in the middle of the cladding plate. The central axis of the through hole is perpendicular to the cladding plate. The support plate is set parallel to the cladding plate. The bottom of the support plate is connected to the cladding plate through an L-shaped support frame. The top of the support plate has a support groove that matches the shape of the stainless steel pipe. The support groove and the central axis of the through hole are on the same straight line. One side of the stainless steel pipe passes through the through hole and is welded to the cladding plate. The other side is set in the support groove and is welded to the support plate. Compression fittings for connecting pipelines are installed at both ends of the stainless steel pipe.

[0007] Furthermore, the L-shaped support frame includes a horizontal plate and a vertical plate. The horizontal plate is vertically connected to the cladding plate, and the bottom of the vertical plate is connected to the side of the horizontal plate away from the cladding plate. The vertical plate is perpendicular to both the horizontal plate and the cladding plate, and the support plate is installed on the top of the vertical plate.

[0008] Furthermore, the top of the upright plate has a first slot for inserting a support plate, and the support plate is inserted into the first slot. The bottom of the support plate has a second slot for inserting an upright plate, and the upright plate is inserted into the second slot.

[0009] Furthermore, the upright plate has two sections arranged side by side.

[0010] The advantages of this utility model are:

[0011] (1) By setting a support plate on one side of the cladding plate, when the cladding plate is welded to the bulkhead or deck, one side of the stainless steel pipe is inserted into the through hole of the cladding plate and the other side is placed in the support groove of the support plate. The bottom of the stainless steel pipe forms two-point support, which is stable and easy to operate. During the welding process, the verticality of the stainless steel pipe to the bulkhead or deck can be effectively maintained, and the installation accuracy is high.

[0012] (2) The L-shaped support frame of this utility model includes a horizontal plate and a vertical plate. The horizontal plate is vertically connected to the cladding plate. The bottom of the vertical plate is connected to the side of the horizontal plate away from the cladding plate. The vertical plate is perpendicular to the horizontal plate and the cladding plate. This design minimizes the obstruction of the cladding plate by the L-shaped support frame and will not have an adverse effect on the welding of the stainless steel pipe and the cladding plate.

[0013] (3) By opening interlocking slots on the support plate and the upright plate, this utility model can help maintain the perpendicularity of the support plate and the upright plate, and can also position the support plate on the upright plate to ensure that the support slot on the support plate is coaxial with the through hole of the composite plate after the support plate is installed.

[0014] (4) This utility model improves the positional stability of the support plate by setting two parallel vertical plates under the support plate, and avoids the support plate from tilting and affecting the installation accuracy of the stainless steel pipe. Attached Figure Description

[0021] Example

[0022] This embodiment provides a small-diameter stainless steel pipe penetration fitting, such as... Figure 1-4 As shown, it includes a stainless steel pipe 3, a composite plate 2, and a support plate 4.

[0023] The cladding plate 2 is welded to the bulkhead or deck 1. A through hole 21 for a stainless steel pipe 3 to pass through is opened in the middle of the cladding plate 2. The central axis of the through hole 21 is perpendicular to the cladding plate 2. The support plate 4 has an arc-shaped structure and is set parallel to the cladding plate 2. The bottom of the support plate 4 is connected to the cladding plate 2 through an L-shaped support frame. The top of the support plate 4 has a support groove 42 that matches the shape of the stainless steel pipe 3. The support groove 42 is on the same straight line as the central axis of the through hole 21. One side of the stainless steel pipe 3 passes through the through hole 21 of the cladding plate 2 and is welded to the cladding plate 3. The other side is set in the support groove 42 of the support plate 4 and is welded to the support plate 4. Both ends of the stainless steel pipe 3 are equipped with compression fittings 7 for connecting pipelines.

[0024] In this embodiment, the L-shaped support frame includes a horizontal plate 6 and vertical plates 5. The horizontal plate 6 is located on the side of the cladding plate 2 away from the bulkhead or deck 1, and is vertically welded to the cladding plate 2. To improve the positional stability of the support plate 4 and prevent the support plate 4 from tilting and affecting the installation accuracy of the stainless steel pipe, there are two vertical plates 5 arranged side by side. The bottom of each vertical plate 5 is welded to the side of the horizontal plate 6 away from the cladding plate 2. The vertical plates 5 are perpendicular to the horizontal plate 6 and to the cladding plate 2, effectively reducing the obstruction of the L-shaped support frame on the cladding plate 2 and reducing the adverse effects on the welding of the stainless steel pipe 3 to the cladding plate 2. Each upright plate 5 has a first slot 51 at its top for inserting a support plate 4, and two second slots 41 at its bottom for inserting two upright plates 5 respectively. The support plate 4 is inserted into the first slots 51 of the two upright plates 5, and each upright plate 5 is inserted into the corresponding second slot 41. This connection method helps to maintain the perpendicularity of the support plate 4 and the upright plate 5, and also allows for positioning of the support plate 4 on the upright plate 5, ensuring that the support groove 42 on the support plate 4 is coaxial with the through hole 21 of the cover plate 2 after the support plate 4 is installed.

[0025] When installing the through-hole component, first weld the cladding plate 2 to the bulkhead or deck 1, then insert the support plate 4 into the upright plate 5, and then insert the stainless steel pipe 3 into the through hole of the cladding plate 2 and place it in the support groove of the support plate 4. Weld the joint between the stainless steel pipe 3 and the cladding plate 2, as well as the joint between the stainless steel pipe 3 and the support plate 4. The operation is convenient and can effectively maintain the perpendicularity of the stainless steel pipe 3 to the bulkhead or deck 1, with high installation accuracy.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
