Embodiment 1

[0035] Example 1: See Figure 1-6 , a marine air-conditioning condensate pipeline vacuum valve, comprising a lower valve body 1, the top of the lower valve body 1 is provided with an upper valve body 6, the top of the upper valve body 6 is provided with a valve cover 7, and the interior of the lower valve body 1 is provided with There is an overflow passage 2, a cleaning structure 3 is provided inside the lower valve body 1, a sealing structure 5 is provided inside the upper valve body 6, a support groove 8 is fixedly connected to the bottom end of the valve cover 7, and a support groove 8 is provided inside the support groove 8. There is an anti-friction structure 9, a valve interface 10 is provided on one side of the upper valve body 6, and an installation structure is provided between the lower valve body 1 and the upper valve body 6;

[0036] see Figure 1-6 , a marine air-conditioning condensate pipeline vacuum valve also includes an installation structure, the installat...

Embodiment 2

[0039]Embodiment 2: cleaning structure 3 is made up of chute 301, slide block 302, semicircle 303, scraper 304 and cleaning brush 305, and semicircle 303 is arranged on the inside of lower valve body 1, and one end of semicircle 303 is provided with Two sets of sliders 302, the other end of the semi-circular ring 303 are fixedly connected with a scraper 304, the bottom of the scraper 304 is fixedly connected with seven sets of cleaning brushes 305, and the inside of the lower valve body 1 is provided with two sets of chute 301;

[0040] The chute 301 is in the shape of "I", and the slider 302 is embedded in the chute 301 and is slidably connected with the chute 301;

[0041] The semi-circular ring 303 is provided with two groups and is symmetrically distributed with respect to the vertical center line of the lower valve body 1;

[0042] There are seven groups of cleaning brushes 305, and the cleaning brushes 305 are distributed at equal intervals at one end of the semicircular...

Embodiment 3

[0044] Embodiment 3: The sealing structure 5 is composed of a sealing ring 501, a rubber ring 502, a block 503 and a slot 504. The sealing ring 501 is arranged inside the upper valve body 6, and the inside of the sealing ring 501 is provided with a rubber ring 502. The rubber ring Twelve sets of clamping blocks 503 are arranged on the outside of the sealing ring 502, and twelve sets of clamping grooves 504 are arranged on the inside of the seal ring 501;

[0045] Twelve groups of clamping blocks 503 are arranged, and the clamping blocks 503 are distributed in a ring shape outside the rubber ring 502, and the clamping blocks 503 are embedded in the inside of the clamping groove 504;

[0046] Specifically, as figure 1 and Figure 5 As shown, there is leakage at the connection between the upper valve body 6 and the lower valve body 1. In order to improve the sealing performance of the vacuum breaking valve, a set of sealing rings 501 need to be arranged inside the upper valve bo...

Abstract

The invention discloses a vacuum breaking valve for a condensed water pipeline of a marine air conditioner. The vacuum breaking valve comprises a lower valve body, an upper valve body is arranged at the top end of the lower valve body, a valve cover is arranged at the top end of the upper valve body, and an overflowing channel is formed in the lower valve body. According to the vacuum breaking valve for condensed water pipeline of marine air conditioner, through mounting blocks, connecting blocks, connecting grooves and fixing bolts, when vacuum in a system reaches a certain value, the vacuum breaking valve can be automatically opened, air is guided in, and vacuum in the system is eliminated, so that the system is protected, when the system works normally, the vacuum breaking valve is sealed tightly, so that leakage of a working medium is avoided, once the vacuum breaking valve goes wrong, the connecting blocks on the two sides of the upper valve body can be taken out from the interiors of the connecting grooves in the two sides of the lower valve body by taking down the fixing bolts so that the valve can be disassembled, the structure improves the working efficiency of the vacuum breaking valve and protects a system, and the problems that the automatic adjusting effect is poor, and the valve is inconvenient to disassemble and overhaul are solved.

Description

technical field [0001] The invention relates to the technical field of air-conditioning condensate water systems of luxury cruise ships and marine engineering, in particular to a vacuum breaking valve for marine air-conditioning condensate water pipelines. Background technique [0002] With the rapid development of water transportation, more and more cruise ships and ships are used to transport goods and carry passengers. The condensate pipes of air conditioners on ships need to be controlled by vacuum breaking valves. The gas in the condensate pipes of air conditioners may contain toxic or explosive Inhaling air during the negative pressure period after installing the vacuum breaking valve can ensure that the gas in the system will not overflow, and greatly maintain the airtightness and safety of the pipeline. However, the existing vacuum breaking valves still have some shortcomings in use. , For example, the installation of the vacuum breaking valve is cumbersome, which ma...
