Later, when sewage needs to be discharged, the electric push rod is started to drive the sealing plate to move up, thereby canceling the partition of the sewage channel, and then the sewage is discharged through the sewage channel; but during the use of the sewage valve, when the sewage valve needs to be installed on the sewage pipe, one side of the sewage valve needs to be fitted with the port of the sewage pipe first, and then a staff member is asked to stabilize the sewage valve to prevent the sewage valve from moving at will, and then another staff member is asked to quickly penetrate the bolts through the sewage valve and connect it with the sewage pipe to complete the installation of the sewage valve. However, this installation method is time-consuming and labor-intensive, and requires multiple staff members to cooperate with each other to complete the installation. It is not convenient, which affects the use of the sewage valve. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The utility model provides a technical solution: a drain valve that is easy to install, including a drain valve body 1, a drain channel 2 and a sealing plate 4, a drain channel 2 is opened inside the drain valve body 1, and an electric push rod 3 is connected to the top side of the drain valve body 1 through a fixing frame, and the output end of the electric push rod 3 is connected to the sealing plate 4 through an extension rod, and a supporting mechanism 5 is arranged on the outer wall of the sealing plate 4, and the supporting mechanism 5 includes a positioning pin 51, a rotating seat 52, a threaded rod 53, a threaded cylinder 54, a fixing plate 55 and a rubber limiting pin 56, the outer wall of the drain valve body 1 is butted with positioning pins 51 on both sides, and the two bottom ends of the drain valve body 1 are connected to the drain channel 2, and the electric push rod 3 is connected to the sealing plate 4 through an extension rod ... A rotating seat 52 is docked on the side; a threaded rod 53 is connected inside the rotating seat 52, and a threaded barrel 54 is threadedly connected to the outer wall of the threaded rod 53; a fixing plate 55 is welded to the side of the threaded barrel 54 away from the rotating seat 52, and a rubber limit pin 56 is docked in the middle of the outer wall of the threaded barrel 54; a limit hole docked with the rubber limit pin 56 is provided at the bottom end of the outer wall of the sewage valve body 1, and the rotating seat 52 is symmetrically distributed about the vertical center line of the sewage valve body 1; the sealing plate 4 is slidably connected to the sewage valve body 1, the threaded rod 53 is rotationally connected to the rotating seat 52, and the outer wall of the rotating seat 52 is welded to the sewage valve body 1.

[0024] In the specific implementation, in order to facilitate people to discharge sewage, when the sewage valve is needed to assist, when the sewage valve body 1 needs to be installed on the sewage pipe, because the sewage valve body 1 is connected with the positioning pin 51, the sewage valve body 1 is manually moved first, so that the positioning pin 51 is connected with the preset through hole on the sewage pipe, and then the sewage valve body 1 is limited to prevent the sewage valve body 1 from moving arbitrarily during installation, resulting in installation dislocation;

[0025] Since the rotating seat 52 is connected to the threaded rod 53, the threaded rod 53 and the threaded barrel 54 are threadedly connected. Then, the threaded rod 53 is rotated by the rotating seat 52, so that the rubber limit pin 56 is disconnected from the drain valve body 1 until the threaded barrel 54 is in a vertical state. Then, the threaded barrel 54 is rotated downward. Since the threaded barrel 54 is connected to the fixing plate 55, the threaded barrel 54 moves downward and drives the fixing plate 55 to move together until the fixing plate 55 is in contact with the ground.

[0026] Then, the drain valve body 1 is auxiliary supported, and when the drain valve body 1 is installed, it is not necessary for a worker to hold the drain valve body 1 steady before installation. After the drain valve body 1 is installed, the middle of the drain valve body 1 can be auxiliary supported by the fixing plate 55, thereby improving the stability of the drain valve body 1, thereby facilitating installation and auxiliary support during the use of the drain valve.

[0027] When the fixing plate 55 is not needed for auxiliary support, the threaded barrel 54 only needs to be rotated along the rotating seat 52 so that the threaded barrel 54 is close to the sewage valve body 1 and is in a horizontal state. At this time, the rubber limit pin 56 is connected to the sewage valve body 1 to form a snap connection, thereby limiting the threaded barrel 54 to prevent the threaded barrel 54 from moving at will, thereby making it convenient for people to store the threaded barrel 54.

[0028] See also Figure 1 , Figure 2 and Figure 5 It can be known that an auxiliary mechanism 6 is arranged inside the sewage valve body 1, and the auxiliary mechanism 6 includes a threaded column 61, a blocking plate 62, a limit seat 63, a filter screen 64 and a spring 65. The side of the sewage valve body 1 away from the sealing plate 4 is threadedly connected with the threaded column 61; the bottom end of the threaded column 61 is connected to the blocking plate 62 through a bearing seat, and the side of the sewage valve body 1 close to the blocking plate 62 is docked with the limit seat 63; the filter screen 64 is slidably connected inside the limit seat 63, and a spring 65 is connected to one side of the outer wall of the filter screen 64; an elastic telescopic mechanism is formed between the limit seat 63, the filter screen 64 and the spring 65, the spring 65 is connected to the limit seat 63, the outer wall of the limit seat 63 and the sewage valve body 1 are fixedly connected, and the blocking plate 62 and the sealing plate 4 are parallel to each other.

[0029] In specific implementation, in order to facilitate people to discharge sewage, the sewage valve needs to assist, when it is necessary to close the sewage channel 2, but the electric push rod 3 fails and cannot drive the sealing plate 4 to move down, because the sewage valve body 1 and the threaded rod 53 are threadedly connected, the bottom end of the threaded rod 53 is connected with the blocking plate 62 through the bearing seat, the threaded column 61 is manually rotated first, so that the blocking plate 62 moves down to block the sewage channel 2, and then the sewage channel 2 is manually blocked, so that when the electric push rod 3 fails, the sewage channel 2 can also be manually blocked, and then the sewage valve body 1 is stably blocked;

[0030] When the sewage is discharged through the sewage discharge channel 2, the sewage is filtered through the filter screen 64, thereby blocking the larger debris in the sewage. When the sewage is discharged, it will impact the filter screen 64, so that the filter screen 64 moves along the limit seat 63 in the direction away from the blocking plate 62. Then, when the filter screen 64 moves, it squeezes the spring 65, causing the spring 65 to deform. When the sewage is discharged, the spring 65 is reset, so that the filter screen 64 returns to its position and collides with the limit seat 63.

[0031] Then, the debris blocked by the filter screen 64 is automatically shaken off from the outer wall to prevent it from clogging the filter screen 64 and causing a decrease in the filtering effect, thereby facilitating stable sealing and filtering and preventing clogging during the use of the sewage valve.

[0032] To sum up, when this easy-to-install drain valve is used, the drain valve body 1 is first connected to the drain pipe, and then the drain valve is fixed to the drain pipe by a flange and bolts. When it is necessary to drain sewage, the electric push rod 3 is started to drive the sealing plate 4 to move upward, thereby canceling the partition of the drain channel 2, and then draining sewage through the drain channel 2. This is the existing technology and will not be elaborated on here. The drain valve is limited by the support mechanism 5 to prevent it from moving at will when installing the drain valve, and the drain valve is auxiliary supported, so that people do not need to hold the drain valve steady for installation. The drain channel 2 is manually sealed by the auxiliary mechanism 6, thereby stably sealing the drain valve body 1, and automatically shaking off the debris blocked by the filter screen 64 from the outer wall to prevent it from clogging the filter screen 64 and causing the filtering effect to decrease. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.

[0033] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
