The invention discloses an anti-blockage backflush double-valve device which comprises a front-end valve, a rear-end valve, a first filter screen, a second filter screen, a water inlet, a water outlet, a first side pipe, a second side pipe, a first small valve and a second small valve, wherein the front-end valve and the rear-end valve are arranged in series; the water inlet is arranged at the left end of the front-end valve; the water outlet is arranged at the right end of the rear-end valve; the first filter screen is arranged at the middle of a pipe on the left side of the rear-end valve; a second filter screen is arranged on a pipe on the right side of the rear-end valve; one end of the first side pipe is connected with the side wall at the left end of the front-end valve; the other end of the first side pipe is connected with the rear-end valve; one end of the second side pipe is connected onto a pipe on the right side of the front-end valve; the other end of the second side pipe is connected with the rear-end valve; the second side pipe is arranged on the left side of the first filter screen; the first small valve is arranged on the first side pipe; and the second small valve is arranged on the second side pipe. The anti-blockage backflush double-valve device disclosed by the invention has the advantages that the structure is simple, the use is convenient, the backflush effect is good, the blockage and the loss are reduced, and the conveying efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of valves, in particular to an anti-blocking recoil double valve. Background technique [0002] Valve (Valve) is a mechanical device that controls the flow, flow direction, pressure, temperature, etc. of the flowing fluid medium. Valves are the basic components in the piping system. Valve fittings are technically the same as pumps and are often discussed as a separate category. The valve can be operated manually or by handwheel, handle or pedal, and can also be controlled to change the pressure, temperature and flow of the fluid medium. [0003] The valve device used in the prior art, after a long time of use, will be corroded to varying degrees due to the erosion of the fluid medium, and once there are problems such as impurities in the fluid, it will be blocked. Especially if a filter is installed in the valve, if there are blocked impurities on the filter, the valve will be blocked as a whole, causing t...
