Abstract
The invention relates to a tree type water guide device of a closed water tank of a box type non-negative-pressure water supply device. The tree type water guide device comprises the water tank, a main pipeline, branch pipes and water suction balls. The main pipeline is arranged in the water tank, and the water suction balls are arranged at the bottom end of the main pipeline. The top end of the main pipeline extends out of the water tank, and the main pipeline is in a tree shape. The brand pipes are arranged on the two sides of the main pipeline respectively, and the top end of each branch pipe is provided with the corresponding water suction ball. The tree type water guide device is wide in water suction range and convenient to install. All the pipelines are made of food-grade stainless steel smooth materials and are firmly welded. 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, bacterial breeding is not likely to happen, and water quality is well guaranteed.
Description
Technical field
The present invention relates to the tree-shaped priming device of a kind of box type negative-pressure-free supply equipment airtight water tank.
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 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, and water body is contaminated, after user will drink contaminated water, serious harm will be healthy.
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 is unreasonable, cannot realize without dead angle diversion in practice and eliminate aquitard.
Summary of the invention
The present invention is directed to above-mentioned deficiency and provide the tree-shaped priming device of a kind of box type negative-pressure-free supply equipment airtight water tank.
This practicality adopts following technical scheme:
The tree-shaped priming device of a kind of box type negative-pressure-free supply equipment airtight water tank of the present invention, comprises water tank, main pipeline, arm, water suction bulb; Be provided with main pipeline in water tank, the bottom of main pipeline is provided with water suction bulb, and water tank is extended on the top of main pipeline; Main pipeline is tree-shaped; The both sides of main pipeline arrange some arms respectively, and the top of each arm is provided with water suction bulb.
The tree-shaped priming device of box type negative-pressure-free supply equipment airtight water tank of the present invention, tree-shaped main pipeline both sides are uniformly distributed 4-8 arms respectively.
The tree-shaped priming device of box type negative-pressure-free supply equipment airtight water tank of the present invention, is characterized in that: a described length of tube is 0.2-0.3 B.
Beneficial effect
The present invention's tree-shaped priming device water suction scope is wide, is convenient to install.All pipelines all adopt the smooth material of food-grade stainless steel, firm welding.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.
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: the tree-shaped priming device of a kind of box type negative-pressure-free supply equipment airtight water tank, comprises water tank 1, main pipeline 2, arm 3, absorb water bulb 4; Be provided with main pipeline 2 in water tank 1, the bottom of main pipeline 2 is provided with water suction bulb 4, and water tank 1 is extended on the top of main pipeline 2; Main pipeline 2 is in tree-shaped; The both sides of main pipeline 2 arrange some arms 3 respectively, and the top of each arm 3 is provided with water suction bulb 4.
The present invention is the tree-shaped priming device of box type negative-pressure-free supply equipment airtight water tank, adopts stainless steel.This priming device is pressed corresponding construction form and is made, and it is once pre-formed that tree-shaped priming device supervisor adds supervisor's water suction bulb, and arm uniform welding is in tree-shaped supervisor relevant position, and the circular bulb of arm is welded in arm end.
Tree-like main pipeline and water tank vertical consistency, be arranged in the position of water tank axis of symmetry, installs a circular water suction bulb on main pipeline top.The pipe of drawing money on credit wherein installing a reasonable length in the direction pointing to water tank four corners respectively extend into the corner place of water tank.Install 2-4 short arm at the zone line of two pipes of drawing money on credit in the every side of main pipeline, the length of short arm is approximately 0.2-0.3 B, and B is the wide of water tank.
Tree-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 on arm, bulb diameter is (1.5-2.5) D, bulb diameter that supervisor absorbs water is (2-3) 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: first water tank bottom various piece water body sucks in tree-shaped arm by circular bulb, and then water body imports in tree-shaped supervisor, then pumps out airtight water tank by the outlet pipe that caliber is larger.
The present invention's tree-shaped priming device water suction scope is wide, is convenient to install.All pipelines all adopt the smooth material of food-grade stainless steel, firm welding.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.
