Description
Technical field
This utility model belongs to water meter field, is specifically related to a kind of water conservancy diversion frame.
Background technology
Water meter is one of measuring instrument that in field of flow measurement, usage amount is maximum, use face is the widest, description is the most complete.China is water meter big producing country in the world, and China's not only water meter production has accounted for 1/3rd of the whole world, and export volume is the most constantly increasing.Large-diameter water meter is divided into vertical Woltmann water meter and horizontal screw wing type water meter, vertical Woltmann water meter and horizontal screw wing type water meter to broadly fall into velocity type water meter.Water flow trace in vertical Woltmann water meter is as follows: current are pressed horizontal axis direction and entered water meter, then rotate along the impeller that vertical axis direction impact water meter spiral shell is wing, turn the most again horizontal direction and flow out.I.e. water is bottom in and top out in water meter.By thimble vertical support, (horizontal screw wing type water meter spiral shell winged petiole wheel is horizontally mounted the spiral shell winged petiole wheel of vertical spiral shell wing water meter, supported by two ends lining, gravity is downward), contact surface is little, frictional force is the least, and vertically arranged spiral shell winged petiole wheel easily reaches balance (no matter dynamic equilibrium or static equilibrium), so the water meter of identical bore, the low discharge metering performance of vertical Woltmann water meter is better than horizontal screw wing type water meter and rotor water gauge, highly sensitive, range ratio is the biggest, and at present, vertical Woltmann water meter nominal bore is the large-diameter water meter of more than 50mm.
Existing small diameter watermeter is rotor water gauge and volumetric water meter, volumetric water meter is installed in the duct, gradually it is full of by some and the room of known volume of exhaust fluid and the water meter that forms by fluid-operated mechanism, or it being called for short quantitative emission type water meter, volumetric water meter typically uses piston cylinder operator.Though volumetric water meter measuring accuracy can reach C level (being equivalent to Q3/Q1=160 in new standard), but due to many reasons (water quality, installation process control etc.), use few at home.The nominal bore used in China market is 40mm and following water meter is rotor water gauge.This water meter is the heaviest, consumable material, and by structure influence, the measuring accuracy of water meter is low, and measuring accuracy typically can only achieve B level (being equivalent to Q3/Q1=80 in new standard).Not having nominal bore on market is 40mm and following vertical helix type and precision reach the water meter of C level.
The rotary wind type small diameter watermeter measuring accuracy currently used can only achieve the B level (the R80 required precision of new standard) of former standard indication, although the watchcase of the rotary wind type small diameter watermeter currently used identical with heavy caliber vertical Woltmann water meter meter casing structure (water (flow) direction is all bottom in and top out form) can install vertical helix type impeller metrological service, but due to this type of water meter housing bottom in and top out to be realized, intake-outlet is maintained on same level axis again, so structure is more complicated, watchcase produces can only use casting, product casting technique difficulty is big, qualification rate is the highest, the watchcase of casting easily seeps water, drainage, product often needs to increase technique and makes (as product is carried out infiltration process) up, the most existing water meter housing should not be improved to vertical Woltmann water meter.
Summary of the invention
For deficiency of the prior art, this utility model provides a kind of water conservancy diversion frame, can not be vertically arranged spiral shell winged petiole wheel in solving existing small diameter watermeter, and precision is not high enough, the problem that the pressure loss is excessive.
This utility model is achieved through the following technical solutions.
A kind of water conservancy diversion frame, including water meter housing, described water meter housing two ends are provided with outlet and water inlet, cavity volume it is provided with between outlet and water inlet, water conservancy diversion frame it is provided with in described cavity volume, described water conservancy diversion frame is made up of the sealing dividing plate A of annular and the upper left curved baffle B and bottom-right curved baffle C of a support and positioning action being positioned at centre, and described water conservancy diversion frame is by injection machine integrated injection molding.nullCavity volume is tiltedly divided into upper and lower two parts by sealing dividing plate A and cavity volume angulation by the cavity volume of water meter housing by water conservancy diversion frame，Water inlet and outlet are separated into, by sealing dividing plate A, two pipelines that can not communicate，The passage being perpendicular to horizontal axis is had to serve guide functions in the middle of water conservancy diversion frame，Water is entered cavity volume lower part by horizontal direction，Vertical direction is transferred in center-aisle，Flow out through cavity volume top half level again，Middle passage can be vertically arranged spiral type impeller metrological service，Thus realize the production of small-bore vertical Woltmann water meter，This creates the terminal measuring accuracy small diameter watermeter more higher than rotor water gauge，The water meter housing of original integration die cavity is changed to by the most through water meter housing，The water conservancy diversion frame of integrated injection molding is detachable，The water meter structure of vertical helix type can also be completed in achieving bore water meter，Not only precision is higher，Pressure loss grade is again smaller than 0.063MPa，The small diameter watermeter that the technique of casting originally obtains，Now due to the simplification of structure，Casting can be changed into red punching，The watchcase compactness produced is bigger，Metal material whole watchcase account for percentage ratio is greatly reduced，Meet country's requirement to water meter innovation.
As preferably, it is provided with diagonal between described water conservancy diversion frame and water meter housing and seals structure.Water conservancy diversion frame and water meter housing realize antileaking after diagonal seals, and diagonal seals simultaneously is for watchcase left and right intake-outlet is divided into not connected two parts.
As preferably, described diagonal seals the groove that structure includes being arranged on water conservancy diversion frame, and described groove runs through curved baffle B, middle sealing dividing plate A and curved baffle C, is provided with sealing ring in described groove, and sealing ring serves integral sealing effect.
Compared with prior art: housing miniaturization, the shell length of the water meter of bore 15 ~ 20mm I accomplishes 80m, greatly reduce metal material proportion in water meter product, housing low cost of manufacture, water conservancy diversion frame integrated injection molding, being vertically arranged of spiral shell winged petiole wheel makes water meter precision high, and pressure loss grade meets national requirements.
