Description
Technical field
The utility model relates to a kind of double-current fast water cap.
Background technology
Water cap is filtration blocking apparatus common in water treatment field.When carrying out water treatment with resin, in industry, substantially all adopt water cap as distribution water inlet member or interception resin component.Conventional water cap is generally made up of upper and lower end cap, screen casing, pull bar and back-up block or thread handle etc., and screen casing is clipped in the middle by upper and lower end cap.When adopting pull bar and support block structure, interlock through upper and lower end cap, screen casing, water hat fixing plate and back-up block successively bottom pull bar, top nut compresses, thus is fixed on installing plate by water cap; When adopting thread handle structure, thread handle is general with bottom end cover one, and compress with pull bar welding between upper and lower end cap, thread handle is through water hat fixing plate, and thread handle top nut clamps from water hat fixing plate opposite side, is fixed on water hat fixing plate by water cap.
In industrial water treatment equipment use procedure, for control appliance runs pressure drop, the water velocity that normal operation flows through water cap gap is often less; And when equipment carries out resin discharging, need larger water velocity back through water cap.In addition, the backwash water flow of resin discharging is often much little than equipment operation discharge.Common filtered water cap can not meet the speed ratio relation of backwash flow velocity and filtration flow-rate.
Utility model content
Its object of the utility model is just to provide a kind of double-current fast water cap, by controlling the screen casing height of high, low speed passage component, can meet the requirement under filtered water flow velocity and backwash flow velocity different process state.Have that structure is simple, the feature of easy installation and removal.
Realize above-mentioned purpose and the technical scheme taked, comprise square toes screw rod, square toes screw rod connects low speed passage component, spool, described square toes screw rod one end is provided with high speed passage component, back-up block, and described low speed passage component, spool, high speed passage component utilize back-up block to be fixed on mount pad after being connected into entirety by square toes screw rod.
Beneficial effect
Compared with prior art the utility model has the following advantages.
1) connect into an entirety by back-up block, square toes screw rod and clamp nut, facilitate installing/dismounting, fast for described double fluid water cap clamp nut is fixed on water cap mount pad;
2) by controlling the height of high, low speed passage component, the requirement under filtered water flow velocity and backwash flow velocity different process state can be met.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is this apparatus structure view one;
Fig. 2 is this apparatus structure view two;
Fig. 3 is low speed passage component structural representation in this device;
Fig. 4 is this device high speed passage component structural representation.
Detailed description of the invention
This device comprises square toes screw rod 1-1, square toes screw rod 1-1 connects low speed passage component 1-2, spool 1-3, as shown in Figure 1 and Figure 2, described square toes screw rod 1-1 one end is provided with high speed passage component 1-4, back-up block 1-5, and described low speed passage component 1-2, spool 1-3, high speed passage component 1-4 utilize back-up block 1-5 to be fixed on mount pad after being connected into entirety by square toes screw rod 1-1.
Described low speed passage component 1-2 comprises sealing platform 3-1, upper end cover 3-2, pull bar 3-3, wire-wrapped screen 3-4 and bottom end cover 3-5, as shown in Figure 3, described high flow rate passage component 1-4 comprises high flow rate upper end cover 4-1, high flow rate wire-wrapped screen 4-2, high flow rate pull bar 4-3 and high flow rate bottom end cover 4-4, as shown in Figure 4, between wire-wrapped screen 3-4 in described high speed passage component 1-4 and low speed passage component 1-2 and high flow rate wire-wrapped screen 4-2, screen pipe opening is 0.2mm, and the gap between upper and lower end cap and wire-wrapped screen is less than 0.15mm.
Described spool 1-3 is the inversion frustum with bolt hole, can fluctuate under hydraulic action along square toes screw rod 1-1.
Embodiment
This device is made up of high speed passage component, low speed passage component, square toes screw rod, spool, back-up block and locking nut.High low speed passage component forms by upper and lower end cap, wire-wrapped screen and the pull bar for fastening upper and lower end cap and screen casing; High speed passage component is coaxial with low speed passage component, and square toes screw rod passes from its axis through-hole, and back-up block is placed on the water hat fixing plate other end, and interlocks with the square termination of square toes screw rod; The square toes screw rod other end is regular screw threads, is connected with locking nut, is buckled on water hat fixing plate after nut by high speed passage component and low speed passage component; Spool is placed between high speed passage component and low speed passage component by square toes screw rod, can fluctuate along screw rod.High speed passage component screen casing height, much smaller than low speed passage component screen casing height, by adjusting high low speed passage component screen casing height, can obtain the water cap of different forward and reverse velocity ratio.
This device embodiment as shown in Figure 1 and Figure 2, is made up of square toes screw rod 1-1, low speed passage component 1-2, spool 1-3, high speed passage component 1-4, back-up block 1-5.Seal is had between low speed passage component 1-2 and square toes screw rod 1-1 and at the bottom of high speed passage component, the screen casing external diameter of high speed passage component 1-4, low speed passage component 1-2 is suitable with the internal diameter size of upper and lower end cap, prevents resin particle from spilling from non-filtered gap; High speed passage component 1-4, low speed passage component 1-2 are made up of upper and lower end cap and pull bar respectively, and whole parts adopt and are welded.Spool 1-3 is arranged in the valve chamber between high, low speed passage component, and spool 1-3 has upper lower platform and screw rod connecting hole, can fluctuate along square toes screw rod 1-1; Described low speed passage component 1-2, spool 1-3, high speed passage component 1-4 utilize back-up block 1-5 to be fixed on mount pad after being connected into entirety by square toes screw rod 1-1.
When the fast water cap of double fluid normally runs, it is position shown in Fig. 2 that spool 1-3 sinks to bottom valve pocket, and filtered water positive flow is through high, low speed passage component; When carrying out backwash, spool 1-3 floats up to position shown in valve pocket top and Fig. 1, blocks the through flow hole bottom low speed passage component 1-2, and now backwashing water can only flow out back through high speed passage component 1-4.Because back flush water outlet can only pass through high speed passage component, the flow velocity of backwashing water can be improved, be conducive to backwash effect; Velocity ratio under different in flow rate can be met by the height of adjustment high, low speed passage component.
