Abstract

The invention relates to a double-flow-rate water cap unit element, which comprises a square head screw rod, wherein the square head screw rod is connected with a low-speed through flow component and a valve core; one end of the square head screw rod is provided with a high-speed through flow component and a support block; the low-speed through flow component, the valve core and the high-speed through flow component are connected in series into a whole through the square head screw rod and is then fixedly arranged on an installing seat by a support block. The requirements under different process states of filter water flow rate and back flushing flow rate can be met through controlling the sieve pipe height of the high-speed through flow component and the low-speed through flow component. The double-flow-rate water cap unit element has the characteristics that the structure is simple, and the mounting and the dismounting are convenient.

Description

technical field [0001] The invention relates to a single element of a double-flow rate water cap. Background technique [0002] The water cap is a common filter interception device in the field of water treatment. When using resin for water treatment, water caps are basically used in the industry as parts for distributing water or intercepting resin. Conventional water caps are generally composed of upper and lower end caps, screen pipes, pull rods, support blocks or threaded handles, etc., and the upper and lower end caps clamp the screen pipes in the middle. When the tie rod and support block structure is adopted, the bottom of the tie rod passes through the upper and lower end covers, the screen tube, the water cap mounting plate and is interlocked with the support block in turn, and the top is pressed with a nut to fix the water cap on the mounting plate; the threaded handle is used During the structure, the threaded handle is generally integrated with the lower end co...
