Abstract
The invention relates to an annular water guide device for a box type non-negative-pressure secondary water supply tank. The annular water guide device comprises the water tank, an annular main pipe, a water outlet pipe, branch pipes and water suction balls. The annular main pipe is arranged in the water tank and communicated with the water outlet pipe. The branch pipes are further arranged on the annular main pipe. Each water suction ball is arranged at one end of the corresponding branch pipe. The annular water guide device for the secondary water supply tank is wide in water suction range and convenient to install. All pipelines are made of food-grade stainless steel smooth materials and are firmly welded. The annular water guide device is wide in water suction range, water in the water tank can be sucked away in time and fully circulated, a dead water zone and a stagnant water layer are avoided, bacteria are not prone to breeding, water quality is well guaranteed, and users can drink healthy water.
Description
Technical field
The present invention relates to a kind of box type negative-pressure-free secondary water supply tank annular priming device.
Background technology
Box type negative-pressure-free water system is primarily of airtight water tank, priming device, supercharging device, main pump unit, frequency-conversion control cabinet, pressurizer, form without vacuum flow amount controller, steady-flow tank and pipeline.Its operating principle is before tap water forced feed user, first tap water is stored in airtight water tank, like this, when with water low-valley interval, tap water pressure is met consumers' demand, and is supplied water to user by tap water pipe network pressure, when in the water use peak period, tap water pressure can not be met consumers' demand, and now supplies user by control piper by after the water pressurization in airtight water tank, thus realizes the water demand meeting user's when section in office.
Wherein because airtight water tank in box type negative-pressure-free supply equipment is as the important deposit water source of second pressure water supply, water quality in its water body and water circulation state most important, as do not ensured, water tank water body fully aspirates when pressurizeing and supplying water, especially there is diversion dead angle in water tank, water body can not get for a long time upgrading and exchanges, meeting breed bacteria in final water body, water body is contaminated, after user will drink contaminated water, be healthyly subject to very large threat, the life security of people time serious, can be jeopardized.
The domestic method for water tank water circulation increases priming device at present, and it is a kind of facility for reducing slough and aquitard in water tank.People's Republic of China's city-building industry standard " box type negative-pressure-free supply equipment CJT 302-2008 " give a kind of priming device form, but this priming device structural configuration not science, cannot realize in practice without dead angle diversion.
Summary of the invention
The present invention is directed to above-mentioned deficiency and provide a kind of box type negative-pressure-free secondary water supply tank annular priming device.
The present invention adopts following technical scheme:
A kind of box type negative-pressure-free secondary water supply tank annular priming device of the present invention, comprises water tank, ring main, outlet pipe, arm, water suction bulb; Be provided with ring main in described water tank, ring main is communicated with outlet pipe, and ring main is also provided with several arms, and one end of arm is provided with water suction bulb.
Box type negative-pressure-free secondary water supply tank annular priming device of the present invention, uniform 12-18 arms on described ring main.
Box type negative-pressure-free secondary water supply tank annular priming device of the present invention, disposed inboard 5-8 arms of described ring main, the outside of ring main is provided with 7-10 arms.
Box type negative-pressure-free secondary water supply tank annular priming device of the present invention, arm horizontal arrangement inside described ring main, the outside arm of ring main is followed successively by level or vertical interlaced shape is arranged.
Box type negative-pressure-free secondary water supply tank of the present invention annular priming device, described wherein four arms extend to four drift angle places of water tank.
Beneficial effect
Box type negative-pressure-free secondary water supply tank annular priming device provided by the invention, water suction scope is wide, is convenient to install.All pipelines all adopt the smooth material of food-grade stainless steel, firm welding.Annular priming device water suction scope is wide, and the water body in water tank can be siphoned away timely, and water body is circulated fully, and can not produce slough and aquitard, bacterium not easily grows, and water quality is well ensured, user can drink healthy water.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in more detail:
As shown in Figure 1: a kind of box type negative-pressure-free secondary water supply tank annular priming device, comprises water tank 1, ring main 2, outlet pipe 3, arm 4, water suction bulb 5; Be provided with ring main 2 in described water tank 1, ring main 2 is communicated with outlet pipe 3, ring main 2 is also provided with several arms 4, and one end of arm 4 is provided with water suction bulb 5.Uniform 12-18 arms 4 on ring main 2.Disposed inboard 5-8 arms 4 of ring main 2, the outside of ring main 2 is provided with 7-10 arms 4.Arm 4 horizontal arrangement inside ring main 2, the outside arm 4 of ring main 2 is followed successively by level or vertical interlaced shape is arranged.Wherein four arms 4 extend to four drift angle places of water tank 1.
The object of the invention is for priming device water suction in existing box type negative-pressure-free water system airtight water tank insufficient, there is the weak point of water suction slough, the water suction bulb be evenly distributed by the ring-like priming device be arranged in bottom airtight water tank improves water absorbing capacity, priming device is made fully to extract in water tank regional especially water body in bottom half 4 corners, greatly reduce slough and aquitard in water tank, improve the quality of casing water body, ensure water safety.
Ring main is arranged to ellipse, and its long axis direction is consistent with casing longitudinal direction, and minor axis is consistent with casing horizontal direction.Ring main road is uniformly distributed 12-18 arms, wherein disposed inboard 5-8 arms, 7-10 arms are arranged in outside.Inner side arm horizontal arrangement, outside arm is arranged as level successively, square crossing is arranged, is wherein arranged vertically and comprises two kinds of modes up and down.4 water tank angles place is stretched into, to ensure that the water body that this place is easily detained fully is aspirated at the horizontal branch pipe installing certain length near water tank corner.
Ring-like priming device material is food-grade stainless steel, pipe wall thickness 5mm, and material is not less than austenitic stainless steel 06Cr19Ni10.Diameter of outflow tube is D, determines according to water suction flow; Arm diameter is (0.7-0.8) D, and circular water suction bulb is installed on each arm place, and bulb diameter is (1.5-2.5) D, suction hole aperture (3-5) mm on water suction bulb, hole count 18-36, uniformity.
When the water use peak period, tap water pressure can not be met consumers' demand, need by the water in airtight water tank by supplying user after the pressurization of feed pump unit.When after starting mode of pump, due to the swabbing action of water pump, in water tank, the outlet pipe generation negative pressure of priming device is aspirated.In water tank, the course of work of priming device is: water tank bottom various piece water body is first by circular bulb suction manifold, and then water body imports in ring main road, then flows out airtight water tank by the outlet pipe that caliber is larger.
