Detailed Description
The following detailed description of the embodiments of the present invention is provided in order to make the technical solution of the present invention easier to understand and understand.
The first embodiment is as follows:
the utility model provides a time delay drainage structures of drain valve, refers to fig. 1 and shows, includes valve body 1, and valve body 1 is provided with the inner chamber, and including the room 11 that thoughtlessly deposits that is used for saving the mixture of steam in the inner chamber. The mixing and storing chamber 11 has a larger space, the valve body 1 has a water discharging end 5, and the lowest position of the water discharging end 5 is higher than the lowest position of the mixing and storing chamber 11, so in the scheme, the water discharging is not completely finished after the valve body 1, but a part of the water is remained in the mixing and storing chamber 11. The effects of water sealing and water storage can be achieved.
Specifically, as can be seen with continued reference to fig. 1, an air passage 12 is provided above the mixing chamber 11 and communicates with the valve chamber 13. The air duct 12 is located above and does not enter the standing water, keeping the compressed air in communication with the valve chamber 13. The valve chamber 13 is provided with a solenoid valve core 2 for controlling the opening and closing of the outlet of the air passage 12. The valve chamber 13 is a vertical cylindrical space. A pressure reducing channel 3 is arranged below the valve chamber 13, one end of the pressure reducing channel 3 is positioned under the solenoid valve core 2 and is controlled by the solenoid valve core 2 to open and close, and the other end of the pressure reducing channel 3 leads to a drainage end 5. The solenoid valve core 2 is kept in a falling state in the initial state, namely the solenoid valve core 2 blocks the pressure reducing channel 3 and simultaneously keeps the air channel 12 communicated with the moisture isolation chamber 4.
Specifically, it can be seen that the water-air separation chamber 4 is also communicated below the valve chamber 13. The water-gas isolation chamber 4 is divided into an upper air chamber 41 and a lower water chamber 42 by a valve diaphragm 43, the valve diaphragm 43 is made of rubber, the edge of the valve diaphragm is limited and clamped on the side wall of the water-gas isolation chamber 4, and the valve diaphragm 43 can deform and displace due to different upper and lower pressures. Therefore, whether the lower water chamber 42 is communicated with the water discharge end 5 or not is controlled by the position and the deformation state of the valve diaphragm 43. When the upper air chamber 41 is filled with compressed air, the upper side of the valve diaphragm 43 is subjected to air pressure of the circular surface, and the lower side of the valve diaphragm 43 is subjected to annular hydraulic pressure, so that the valve diaphragm 43 can close the passage of the drainage end 5 by the air pressure, and the liquid cannot pass through the passage, and drainage is delayed. When the solenoid valve core 2 moves, the compressed air in the upper air chamber 41 is discharged, so that the valve diaphragm 43 is pushed upwards by the water pressure, and the water is discharged.
And a liquid level detector 6 is installed in the mixing and storing chamber 11, the liquid level detector 6 is connected with a controller 7, and the controller 7 is connected with an electromagnetic device and used for controlling the up-and-down movement of the electromagnetic valve core 2.
Through the technical scheme, the controller 7 is internally provided with an upper liquid level value and a lower liquid level value, and when the liquid level in the mixing chamber 11 is at the lower liquid level, the controller 7 controls the solenoid valve core 2 to be at the lower position and closes the pressure reduction channel 3 and simultaneously opens the air channel 12; when the liquid level in the mixing and storing chamber 11 is at an upper liquid level, the controller 7 controls the solenoid valve core 2 to be at an upper position and closes the air channel 12 and simultaneously opens the pressure reducing channel 3. Therefore, automatic drainage is carried out according to the liquid level condition of accumulated water, and the waste of energy and the reduction of the service life cannot be caused.
Based on the above scheme, the volume of the air contained in the valve chamber 13 and the upper air chamber 41 can be designed to be less than 5mL in the design process. The smaller the ease here, the more energy saving it is, since the air will be let out here, as is known.
In addition, as shown in fig. 1, the valve body 1 is provided with a cylinder interface 14 which is used for connecting an air storage cylinder and is positioned above the mixing chamber 11, a water discharge port 15 is arranged below the mixing chamber 11, and the water discharge port 15 is plugged through a plug 151. In the later maintenance process, the residual accumulated water can be released. The operation process is that the port of the air storage cylinder is closed first, and then the plug 151 is directly opened, so that the residual accumulated water can be discharged.
In the scheme, the inner wall of the drainage end 5 is provided with the flow blocking ring 51, the water inlet side of the flow blocking ring 51 is a vertical surface, and the water outlet side of the flow blocking ring 51 is a flaring-shaped inclined surface, so that the designed function is that the water flow is slowed down.
A delayed drainage method adopts the delayed drainage structure of the drainage valve, a drainage port of an air storage cylinder is connected with a valve body 1 to communicate the air storage cylinder with a mixing chamber, the valve body 1 is positioned at the lower part of the air storage cylinder and used for receiving compressed air and accumulated water, drainage is delayed when the accumulated water does not reach an upper liquid level value, the accumulated water is stored in the mixing chamber until the liquid level of the accumulated water reaches the upper liquid level value, a liquid level signal is sent by a liquid level detector 6 at the moment, a controller 7 controls an electromagnetic valve core 2 to move upwards, an inlet of a valve chamber 13 is sealed, a pressure reduction channel 3 is opened, the downward hydraulic pressure of a valve diaphragm 43 is larger than the upper air pressure, automatic drainage is realized, when the liquid level is lower than the lower liquid level value, the controller 7 controls the electromagnetic valve core 2 to move downwards, the valve chamber 13 is opened and communicated with the upper valve chamber 13, and the upper air pressure of the valve diaphragm 43 is larger than the lower water pressure to automatically close drainage.
Example two:

The compressed air can be collected by the airbag 325 on the branch 31, and the airbag 325 can be gradually inflated. When the service environment of the structure is not the air storage cylinder of the air compressor, the structure can be used. Specifically, when we drain the compressed toxic gas, we must isolate the toxic gas, and at this time, in order to prevent the toxic gas and the water from mixing, the handle 323 is operated to guide the toxic gas into the airbag 325 for recycling.
In another usage environment, when it is necessary to add some gas capable of being melted in water to neutralize or add the gas into the water in the drainage end 5, the airbag 325 may be removed for addition, or may be added into the airbag 325 first for filling, and the additive may be gas, or particles, powder, or reagent.
