Description

Pot with no negative pressure
Technical field
The present invention relates to a kind of pot with no negative pressure, belong to the tap water supply apparatus field.
Background technology
At present, in cities and towns building water supply system, generally adopt discharge bay or storage tank water storage, it is bulky, and cost is higher, and causes secondary pollution easily.In order to solve building water supply, the user who has directly draws water with tubing pump, influences other users' water supply on every side owing to producing negative pressure, has violated the urban water supply management method.
Summary of the invention
According to above the deficiencies in the prior art, the technical problem to be solved in the present invention is: the pot with no negative pressure that a kind of volume is little, cost is low, maintenance and installation is easy to use is provided.
This technical scheme of using novel its technical problem of solution to be adopted is: this no negative pressure is irritated, comprise base, tank body, water inlet, delivery port and water pump, it is characterized in that: non-negative pressure valve is set at the tank body top, water inlet connects tap water pipe line, delivery port is connected with the water inlet of water pump, and the delivery port of water pump connects the user.
Fluid level controller is installed on the tank body, and fluid level controller connects water pump.
Water pump is connected main water outlet pipe by the water pump water outlet flap valve with the water pump water outlet gate valve.
Non-negative pressure valve comprises valve body, spool and outer cover, it is characterized in that: spool is a float-ball type, places in the valve body.
The float-ball type spool comprises ball float, joint ring, baffle plate and erosion control cover up and down, guide peg, and last erosion control cover is installed in the top of baffle plate, joint ring is installed in the below of baffle plate, ball float is installed in the joint ring below, and guide peg is installed in the ball float below, and following erosion control cover is fixed on outside the valve body bottom.
Valve body top is provided with upper flange and lower flange, is provided with sealing mat between upper flange and the lower flange, and upper flange and lower flange are bolted to connection.
Joint ring is annular, and is porose on the upper and lower erosion control cover wall, and the valve body bottom is provided with the hole.
The upper flange top is equipped with outer cover, and outer cover and pot with no negative pressure are connected and fixed.
When tap water constantly entered tank body, along with water level constantly raises, the air in the tank body was discharged automatically through non-negative pressure valve.When water level rose to certain water level, non-negative pressure valve was closed automatically, and this moment, tap water still constantly entered, and tank interior pressure increases gradually, and the pressure in final jar equals the pressure of tap water pipe network.When user's water increases or tap water pipe network flow pressure when diminishing, the tank interior water level can descend gradually, when drawdown during to certain value non-negative pressure valve open automatically, connect atmosphere, no negative pressure in the tank body, the interior water of water pump extraction tank body.Big when user's water supply volume, tap water pipe network flow is little or during tap water cut-off, the stopping or open of the fluid level controller control of pump on the tank body.
Compared with prior art, pot with no negative pressure of the present invention has beneficial effect and really is: by at the tank body top non-negative pressure valve being set, water inlet connects tap water pipe line, and delivery port is connected with the water inlet of water pump, and the delivery port of water pump connects the user.Because the effect of non-negative pressure valve, tank interior all keeps malleation under any operating conditions, avoided water pump directly to extract the water of tap water pipe network, has protected water pump, has avoided user's lack of water, and volume is little, can not overstock stagnant water, avoids polluting.In addition because volume is little, so system cost is low, simple in structure, maintenance and installation is easy to use.
Description of drawings
Fig. 1 is a structural representation of the present invention,
Fig. 2 is a non-negative pressure valve structural representation of the present invention.
Fig. 1-2 is the most preferred embodiment of pot with no negative pressure of the present invention, among Fig. 1-2: 27 times erosion control covers of erosion control cover 19,25,26 holes, 20 baffle plate 21 joint rings, 22 ball float 23 valve bodies, 24 guide pegs on 1 non-negative pressure valve, 2 water inlets, 3 tank bodies, 4 fluid level controllers, 5 water pumps, 6 water pump water outlet flap valve, 7 water pump water outlet gate valves, 8 main water outlet pipe, 9 straight-through door 10 delivery ports 11 bases 12 outer covers 13 valve pockets 14 upper flanges 15 bolts 16 sealing mats 17 lower flanges 18
The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing:
As shown in Figure 1, tank body 3 is fixed on the base 11, and tank body 3 sidewalls are provided with water inlet 2, and the bottom is provided with delivery port 10, and the top is equipped with non-negative pressure valve 1.Delivery port 10 connects main water outlet pipe 8 by straight-through door 9.Also be provided with fluid level controller 4 on tank body 3 sidewalls, fluid level controller 4 connects water pump 5.The delivery port of water pump 5 connects the user, and water inlet is connected main water outlet pipe 8 by water pump water outlet flap valve 6 with water pump water outlet gate valve 7.
As shown in Figure 2, non-negative pressure valve 1 comprises valve body 23, spool 13 and outer cover 12, and spool 13 inside are equipped with ball float 22, joint ring 21, baffle plate 20 and last erosion control cover 18 successively, and ball float 22 bottoms are provided with guide peg 24, baffle plate 20 is an annular, up and down on erosion control cover 18,27 walls porose 19,25.Joint ring 21 and baffle plate 20 are fixed on the valve body 23, and valve body 23 bottoms have hole 26, and erosion control cover 27 is installed down.Valve body 23 tops are fixed with upper flange 14, are provided with sealing mat 16 between the lower flange 17 at upper flange 14 and tank body 3 tops, and are fixedly connected by bolt 15.Upper flange 14 tops are equipped with outer cover 12, and outer cover 12 is connected and fixed with pot with no negative pressure 3.
