Abstract
The invention relates to a negative-pressure-free variable frequency water supply device, which comprises municipal tap water, a steady flow compensator, an electro connecting pressure gauge pressure sensor, an additional air filter for a vacuum suppressor, a bypass electric valve and a level gauge, wherein the lower end of the steady flow compensator is provided with a drain opening, a water pump component, a far transmissible pressure gauge, a user and a water pump inlet pipe; one end of the electro connecting pressure gauge pressure sensor is connected with the municipal tap water and the other end of the electro connecting pressure gauge pressure sensor is connected with the steady flow compensator; the additional air filter for a vacuum suppressor is arranged on the steady flow compensator; the bypass electric valve is connected with the water pump component in parallel; and the level gauge is arranged in the steady flow compensator. When pressure of a municipal pipe network is higher than the pressure required by a user, the water supply device uses the pressure of the municipal pipe network to directly supply water to the user through the bypass electric valve, so as to achieve the effect of fully saving energy; when the municipal pipe network stops water for a short time, the water supply device keeps normal water supply to the user, and sucks air in a tank through the vacuum suppressor to prevent generation of negative pressure; and the additional air filter for the vacuum suppressor thoroughly avoids secondary pollution of water.
Description
Technical field
The present invention relates to the water supply field, relate in particular to non-negative pressure frequency-changing water supply device.
Background technology
As seen from Figure 1: traditional water supply pattern is earlier water tank (pond) to be put in the municipal tap water from pipe network, is supplied water to the user by force (forcing) pump again.So just municipal ductwork pressure is wasted, fetch water,, then be easy to generate negative pressure, other users' of influence periphery water as no effective measures if water pump directly is connected on the city planting ductwork.Among the figure: municipal tap water 10, pond or water tank 11, float valve 110, pump water inlet 12, water pump component 13, pressure sensor 14, the user 15.
In order to change above-mentioned defective, adopt common non-negative pressure water-supply installation (as shown in Figure 2), before the force (forcing) pump group, installed a steady flow compensator and vacuum suppresser additional and eliminated negative pressure, in case but the city planting ductwork short-term cut off the water, the user is anhydrous available, and reliability of water supply is on the low side.For important institutional settings such as luxurious hotel, dwelling house and armies, this kind way of supplying water is not too suitable again like this.Among the figure: municipal tap water 20, pressure vacuum gauge 21, vacuum suppresser 22, steady flow compensator 23, water pump component 24, pressure sensor 25, the user 26, pump water inlet 27.
How with the advantages of said two devices together, the shortcoming of avoiding taking place the two again is the problem that engineers and technicians need solve.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of non-negative pressure frequency-changing water supply device, are intended to solve the problems of the technologies described above.
In order to address the above problem, the present invention is achieved by the following technical solutions:
The present invention includes: the municipal tap water, steady flow compensator, the steady flow compensator lower end is provided with discharge opening, water pump component, teletransmission pressure meter, user, pump water inlet; Also comprise: one one end and the electro connecting pressure gauge (pressure sensor) that the municipal tap water joins, the other end and steady flow compensator are joined; A vacuum suppresser additive air strainer that is placed on the steady flow compensator; One with water pump component and the bypass motor operated valve that connects; A content gauge that is placed in the steady flow compensator.
Compared with prior art, the invention has the beneficial effects as follows: make full use of municipal ductwork pressure during greater than user's request pressure at municipal ductwork pressure and directly supply water, reach fully energy-conservation effect to the user by the bypass motor operated valve; When the city planting ductwork short-term is cut off the water, keep to user's normal water supply, and by vacuum suppresser air-breathing generation that prevents negative pressure in jar; The secondary pollution that vacuum suppresser additive air strainer has thoroughly been stopped water quality.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
As seen from Figure 3: the present invention includes: municipal tap water 30, steady flow compensator 33, the steady flow compensator lower end is provided with discharge opening 40, water pump component 34, teletransmission pressure meter 35, the user 36, pump water inlet 37; Also comprise: one one end and the electro connecting pressure gauge 31 that municipal tap water 30 joins, the other end and steady flow compensator 33 are joined; A vacuum suppresser additive air strainer 32 that is placed on the steady flow compensator 33; One with water pump component 34 and the bypass motor operated valve 38 that connects; A content gauge 39 that is placed in the steady flow compensator 33;
Before described pump water inlet 37, can also settle a ultraviolet sterilizer 41.
The present invention installs electro connecting pressure gauge at water inlet, sets up the bypass motor operated valve in the water outlet bypass, vacuum suppresser additive air strainer.One end of steady flow compensator delivery port and two groups of frequency conversion booster pump assemblies and motor operated valve bypass also connects, can also be at steady flow compensator delivery port participation in the election ultraviolet sterilizer, the other end of two groups of frequency conversion booster pump assemblies and bypass joins with the outlet pipe that is connected the user, and at user's outlet pipe place the teletransmission pressure meter is installed.
On electro connecting pressure gauge, get a upper pressure limit and a low pressure limit.Upper pressure limit is as bypass motor operated valve working signal.When upper pressure limit occurred, PLC received signal and stops the pump group, and the motor operated valve of adhesive is simultaneously opened bypass duct, directly supplied water with municipal ductwork pressure and gave the user, reached the ductwork pressure utilization, the effect of conserve energy.Low pressure limit is shut down usefulness as the pump group, and low pressure limit occurs when ductwork pressure is lower than limiting pressure, and PLC receives the low pressure limit signal and cuts away the pump group, and all water pumps quit work, and prevents because of the excessive extraction pipe network water of the not enough unit of municipal ductwork pressure.When pressure is between upper pressure limit and low pressure limit, be considered as the operate as normal section.The work of pump group is according to the pressure signal work of teletransmission pressure meter feedback at this moment.Vacuum suppresser additive air strainer can (be stopped the secondary pollution through outside air) and not destroy the normal water supply in the network of rivers from the beginning under the situation that guarantees water quality, and prevents that the negative pressure in the current stabilization jar from producing.When the city planting ductwork short-term is cut off the water, maintenance is to user's normal water supply, when water supply volume during greater than output, water storage replenish user in the steady flow compensator is used, just can produce the action of negative pressure vacuum suppresser this moment in the steady flow compensator, outside air be purified the generation of eliminating negative pressure in the suction tank of back through air filter.Content gauge is housed in the steady flow compensator, provides no water conservation to the pump group, in addition, can also be at steady flow compensator delivery port participation in the election ultraviolet sterilizer.Complete equipment adopts hermetically sealed, all steel structure, has thoroughly stopped run, drip, leak, oozes, the phenomenon of waste water resource such as cleaning.
