Problems solved by technology
[0002] In the traditional liquid pipeline transportation, due to the long distance, the pipeline is easily oxidized and corroded during use or the pipeline is easily polluted by dust particles during the installation process, resulting in the liquid being transported easily mixed with impurities or the transmission pressure is not enough. Therefore, it is often necessary to use elastic seated gate valves for filtration and discharge treatment. However, the current elastic seated gate valves often have the problems of poor discharge effect and low filtration quality. After filtering, the filter screen needs to be replaced frequently, wasting a lot of Human and material resources

The invention relates to the field of water pumps, in particular to a flange type resilient-seated gate valve. The flange type resilient-seated gate valve comprise a gate valve body and further comprises a flange pipeline connecting device, a seal device, a discharging and filtering device and a filtration angle adjuster; the gate valve body comprises a first valve body, a second valve body embedded into the bottom of the first valve body, a valve rod, a valve plate and a hand wheel which is arranged on the top of the first valve body, and the hand wheel penetrates through the first valve bodyand the second valve body through the valve rod and is connected with the valve plate arranged on the second valve body; the seal device is installed on the outer side of the valve plate. By means ofthe flange type resilient-seated gate valve, people can adjust gate sealing actions through the hand wheel; besides, due to the arrangement of the discharging and filtering device, the fluid which needs to be filtered is smoothly discharged, and the impurities are smoothly filtered; when the remaining impurities after filtration seriously influence the flow discharging effect, the filtration angle adjuster is manipulated so as to switch the fluid impurities, and therefore, the filtration can be stably and continuously conducted.

technical field [0001] The invention relates to the field of water pumps, in particular to a flange type elastic seated gate valve. Background technique [0002] In the traditional liquid pipeline transportation, due to the long distance, the pipeline is easily oxidized and corroded during use or the pipeline is easily polluted by dust particles during the installation process, resulting in the liquid being transported easily mixed with impurities or the transmission pressure is not enough. Therefore, it is often necessary to use elastic seated gate valves for filtration and discharge treatment. However, the current elastic seated gate valves often have the problems of poor discharge effect and low filtration quality. After filtering, the filter screen needs to be replaced frequently, wasting a lot of Human and material resources. [0003] Therefore, it is necessary to propose a flange type elastic seated gate valve to solve the above problems. Contents of the invention ...
