The sealing cover is arranged on the heat exchanger shell and positioned on the other side of the seawater cavity, the sealing cover is made of transparent materials, and a sealing cavity is formed between the sealing cover and the heat exchanger shell; the threaded hole is arranged on the heat exchanger shell and is positioned in the sealed cavity; wherein seawater can enter the sealed cavity from the seawater cavity through the threaded hole. The utility model discloses an observation device of heat exchanger zinc block can find out directly perceivedly whether the zinc block needs to be changed.
Description
Technical Field
The utility model relates to a marine engine field especially relates to an observation device of heat exchanger zinc plate of marine engine.
Background
Along with the industrial upgrading of shipbuilding industry, the maintainability requirement of people on marine engines is higher and higher, the marine heat exchanger is generally provided with an anti-corrosion zinc block in order to reduce the corrosion of a shell contacted with seawater, the anti-corrosion zinc block belongs to a consumable product, the traditional anti-corrosion zinc block is generally directly arranged in a cavity of the heat exchanger, and the loss degree of the zinc block cannot be intuitively known; in particular, when the zinc blocks are consumed, if new ones are not replaced in time, this will lead to rapid corrosion of the shell of the heat exchanger in contact with the sea water, eventually leading to corrosive perforation of the shell of the heat exchanger, resulting in failure of the heat exchanger.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information constitutes prior art already known to a person skilled in the art.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an observation device of heat exchanger zinc piece, it can find out directly perceivedly whether the zinc piece needs to be changed.
In order to achieve the above object, the utility model provides an observation device of heat exchanger zinc piece, the zinc piece setting is on heat exchanger shell, and one side of heat exchanger shell has the sea water chamber, and observation device is including sealed lid and screw hole. The sealing cover is arranged on the heat exchanger shell and positioned on the other side of the seawater cavity, the sealing cover is made of transparent materials, and a sealing cavity is formed between the sealing cover and the heat exchanger shell; the threaded hole is arranged on the heat exchanger shell and is positioned in the sealed cavity; wherein seawater can enter the sealed cavity from the seawater cavity through the threaded hole.
In a preferred embodiment, the zinc block is threadably disposed within the threaded bore to inhibit ingress of seawater into the sealed housing through the threaded bore.
In a preferred embodiment, the observation device of the zinc block of the heat exchanger further comprises a sealing gasket which is arranged between the sealing cover and the shell of the heat exchanger.
In a preferred embodiment, the sealing cap and the sealing gasket are fixed to the heat exchanger housing by bolts.
Compared with the prior art, the utility model discloses an observation device of heat exchanger zinc block has following beneficial effect: the transparent sealing cavity is arranged at the position where the zinc block is arranged on the shell of the heat exchanger, and after the zinc block is corroded seriously and seawater enters the sealing cavity, whether the zinc block needs to be replaced can be visually seen, so that the aim of simple maintenance is fulfilled. Meanwhile, the device is simple in structure, low in manufacturing cost, strong in practicability, long in service life and beneficial to popularization and use.

Detailed Description
The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited by the following detailed description.
Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.
As shown in fig. 1, fig. 1 is a schematic structural diagram of an observation device according to an embodiment of the present invention. According to the utility model discloses preferred embodiment's an observation device of heat exchanger zinc block, zinc block 2 sets up on heat exchanger casing 1, and one side of heat exchanger casing 1 has sea water chamber 12, and observation device is including sealed lid 5 and screw hole 11.
In some embodiments, a sealing cover 5 is disposed on the heat exchanger housing 1 at the other side of the seawater cavity 12, and the sealing cover 5 is made of a transparent material. A sealing gasket 4 is arranged between the sealing cover 5 and the heat exchanger shell 1, and the sealing cover 5 and the sealing gasket 4 are fixed on the heat exchanger shell 1 through bolts 3. A sealed cavity 51 is formed between the sealing cover 5 and the heat exchanger shell 1. The threaded hole 11 is arranged on the heat exchanger shell 1 and is positioned in the seal cavity 51, the zinc block 2 is arranged in the threaded hole 11 through threads, and the zinc block 2 can prevent seawater from entering the seal cavity 51 through the threaded hole 11 at ordinary times. However, when the zinc is excessively corroded by seawater, and seawater enters the sealed cavity 51 from the seawater cavity 12 through the threaded hole 11, an operator can see the seawater through the transparent sealing cover 5, and at this time, the zinc block 2 is required to be replaced in time.
To sum up, the utility model discloses an observation device of heat exchanger zinc block has following a bit: the transparent sealing cavity is arranged at the position where the zinc block is arranged on the shell of the heat exchanger, and after the zinc block is corroded seriously and seawater enters the sealing cavity, whether the zinc block needs to be replaced can be visually seen, so that the aim of simple maintenance is fulfilled. Meanwhile, the device is simple in structure, low in manufacturing cost, strong in practicability, long in service life and beneficial to popularization and use.
The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. It is not intended to limit the invention to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiments were chosen and described in order to explain certain principles of the invention and its practical application to enable one skilled in the art to make and use various exemplary embodiments of the invention and various alternatives and modifications as are suited to the particular use contemplated. It is intended that the scope of the invention be defined by the claims and their equivalents.
