Abstract
Description
Technical Field
[0001] This utility model belongs to the field of anti-leakage cover technology, specifically a heat exchanger cover that prevents gas leakage. Background Technology
[0002] A heat exchanger is an energy-saving device that enables heat transfer between two or more fluids at different temperatures. It transfers heat from a higher-temperature fluid to a lower-temperature fluid, allowing the fluid temperature to reach the specified parameters of the process. However, current heat exchanger covers still have shortcomings. The structure of general heat exchanger covers is relatively simple. When the covers are used for a long time, they need to be ventilated. Ventilation is time-consuming and laborious, and foreign objects can easily enter the equipment. At the same time, the poor sealing of the covers makes them inconvenient to use. Summary of the Invention
[0003] To overcome the above-mentioned defects, this utility model provides a heat exchanger cover plate to prevent gas leakage, which solves the shortcomings of the current heat exchanger cover plates. The general heat exchanger cover plate has a relatively simple structure. The cover plate needs to be ventilated during long-term use. The operation of ventilating is time-consuming and laborious, and foreign objects are easy to enter the equipment. At the same time, the poor sealing of the cover plate makes it inconvenient to use.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a heat exchanger cover plate for preventing gas leakage, comprising a cover plate body, a limiting plate fixedly connected to the top of the cover plate body, a plurality of positioning holes being provided at one end of the top of the limiting plate, positioning bolts being provided inside the positioning holes, the positioning bolts passing through the positioning holes and embedded in the cover plate body, and a sliding groove being provided inside the limiting plate.
[0005] A sliding cover is slidably connected inside the sliding groove. A cover handle is fixedly connected to the top of the sliding cover. A filter screen is provided at the bottom of the cover body. Protrusions are fixedly connected to both ends of the filter screen. Fixing holes are opened inside the protrusions. Fixing bolts are provided inside the fixing holes. The fixing bolts pass through the fixing holes and are embedded in the cover body.
[0006] As a further embodiment of this utility model: a connecting hole is provided on the inner bottom side of the cover plate body, and a sealing rubber ring is fixedly connected inside the connecting hole.
[0007] As a further embodiment of this utility model: a heat exchanger body is slidably connected inside the connecting hole, and a limiting groove is formed on the top of the heat exchanger body.
[0008] As a further embodiment of this utility model: a connecting block is fixedly connected to the outer side of the cover plate body, and a pin is provided on one side of the bottom of the connecting block.
[0009] As a further embodiment of this utility model: a limiting block is sleeved on the outer side of the pin shaft, and a buckle is fixedly connected to the outer side of the heat exchanger body.
[0010] As a further embodiment of this utility model: cover handles are fixedly connected to the top two sides of the cover plate body, and the cover handles are semi-circular ring designs.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This heat exchanger cover plate, designed to prevent gas leakage, consists of a cover plate body, a limiting plate, a sliding groove, a sliding cover, a cover handle, and a filter screen. When using this heat exchanger cover plate, to expel gas, the user can apply outward force by holding the cover handle, causing the sliding cover inside the limiting block to move along the sliding groove. When the sliding cover is removed, the filter screen fixedly connected inside the cover plate body can be switched out, thus preventing foreign objects from entering the equipment during gas expulsion and improving the performance of the heat exchanger cover plate for the user.
[0013] This gas-leakage-preventing heat exchanger cover plate, with its connecting block, pin, cover plate handle, buckle, sealing rubber ring, and limiting groove, allows for easy sealing of the heat exchanger. First, the cover plate is held by the handle and fitted onto the top of the heat exchanger body. Then, the sealing rubber ring is fitted into the limiting groove to secure the heat exchanger. Finally, the limiting block is engaged with the buckle to fix the cover plate to the top of the heat exchanger body, thus improving user convenience. Attached Figure Description

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0019] like Figure 1-3 As shown, this utility model provides a technical solution: a heat exchanger cover plate to prevent gas leakage, including a cover plate body 1, a connection hole 18 is provided on the bottom inner side of the cover plate body 1, and a sealing rubber ring 19 is fixedly connected inside the connection hole 18. By setting the connection hole 18, the heat exchanger can be sleeved on the top of the heat exchanger body 11.
[0020] A limiting plate 2 is fixedly connected to the top of the cover body 1, and cover handles 17 are fixedly connected to both sides of the top of the cover body 1. The cover handles 17 are semi-circular ring designs. By setting the cover handles 17, the cover body 1 can be opened easily by holding the cover handles 17 and applying upward force.
[0021] The top end of the limiting plate 2 is provided with several positioning holes 4. The positioning holes 4 are provided with positioning bolts 5. The positioning bolts 5 pass through the positioning holes 4 and are embedded in the cover plate body 1. The limiting plate 2 is provided with a sliding groove 3. The sliding cover 6 is slidably connected inside the sliding groove 3. The top of the sliding cover 6 is fixedly connected with a cover handle 7. By setting the cover handle 7, the sliding cover 7 can be opened by holding the cover handle 7. The bottom of the cover plate body 1 is provided with a filter screen 13. The outer side of the cover plate body 1 is fixedly connected with a connecting block 8. The bottom side of the connecting block 8 is provided with a pin 9.
[0022] The two ends of the filter screen 13 are fixedly connected to the protrusions 14. The protrusions 14 have fixing holes 15 inside. The fixing holes 15 have fixing bolts 16 inside. The fixing bolts 16 pass through the fixing holes 15 and are embedded in the cover plate body 1. The heat exchanger body 11 is slidably connected in the connection hole 18. The top of the heat exchanger body 11 has a limiting groove 20. By setting the limiting groove 20, the sealing rubber ring 19 can be fitted into the limiting groove 20, thereby facilitating the sealing of the heat exchanger.
[0023] A limiting block 10 is sleeved on the outer side of the pin 9, and a buckle 12 is fixedly connected to the outer side of the heat exchanger body 11. By setting the buckle 12, the limiting block 10 can be snapped into the buckle 12, thereby fixing the cover plate body 1 to the top of the heat exchanger body 11.
[0024] The working principle of this utility model is as follows: When the ventilation cover is needed, first, hold the cover handle 17 with both hands to put the heat exchanger cover on the top of the heat exchanger body 11, and then put the sealing rubber ring 19 into the limiting groove 20 to facilitate the sealing of the heat exchanger. Then, the limiting block 10 is snapped into the buckle 12. When using the heat exchanger cover, when ventilation is needed, the pull cover handle 7 can be held to exert force outward, so that the pull cover handle 7 drives the sliding pull cover 6 in the limiting block 10 to move along the sliding groove 3. When the sliding pull cover 6 is removed, the filter screen 13 fixedly connected inside the cover body 1 can be switched out.
