Abstract
The utility model relates to the field of urban secondary pipe network pressure-superposed and non-negative pressure water supply equipment, and discloses a pipe network pressure-superposed water supply flow and air controller. The pipe network pressure-superposed water supply flow and air controller is composed of a flow control device and an air exhaust device. The flow control device comprises a municipal pressure sensor, a digital display controller, a PLC, a water pump speed adjuster, a water pump, and a secondary water supply pressure sensor. The air exhaust device comprises an air exhaust guide pipe and an air exhaust filter valve. The pipe network pressure-superposed water supply flow and air controller can send control signals and control the pressure and the flow of a secondary water supply pump automatically by detecting the pressure and the flow provided by the municipal pipe network, and therefore the secondary water supply flow can be equal to or smaller than the water flow provided by the municipal pipe network, and the phenomenon that the secondary water supply pump extracts the municipal flow directly is avoided. Meanwhile, air inside a tank body is exhausted from the guide pipe, the tank body does not need to be opened, and therefore the sealing performance is improved, and cost is lowered.
Description
Technical field
The utility model relates to that the city secondary pipe network laminates, the non-negative pressure water-supply installation field, particularly relates to a kind of pipe network pressure-superposed water supply gas controller.
Background technology
In the secondary water-supply apparatus field, country forbids strictly any type of supply equipment and directly extracts the municipal tap water ductwork pressure, but in actual applications, as without flow control valve, when water use peak or municipal services pressure decreased, be certain to directly extract municipal discharge, pipe network pressure-superposed water supply flow controller is to be specifically designed to a covering device that detects control secondary water-supply flow.
Simultaneously traditional pipe network Pressure-superposed water supply equipment perforate exhaust above tank body reduces the tank body airtight performance, easily causes secondary pollution in water supply.
The utility model content
Problem to be solved in the utility model provides a kind of gas control device that can effectively avoid the secondary water-supply pump directly to extract municipal flow and can automatically get rid of air-flow in the tank body.
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of pipe network pressure-superposed water supply gas controller.
The technical scheme that the utility model adopts is: a kind of pipe network pressure-superposed water supply gas controller, formed by flow control device and exhaust plant, it is characterized in that: described flow control device comprises: municipal pressure sensor (1) is connected in the tap water water inlet pipe (10), the aobvious control of municipal administration pressure sensor (1) simultaneous connection word instrument (2), numeral aobvious control instrument (2) connects PLC controller (3), PLC controller (3) connects pump speed control device (4), pump speed control device (4) connects water pump (5), in secondary water-supply pressure sensor (6) the access outlet pipe (11), the aobvious control of simultaneous connection word instrument (2); Described exhaust plant comprises: exhaust manifolds (8) enter tank body (9) along tap water water inlet pipe (10), and exhaust manifolds (8) other end connects exhaust trap valve (7), and exhaust trap valve (7) places in the little shielded box of control cabinet (12).
Municipal administration pressure sensor (1) records municipal ductwork pressure and transfers to the aobvious control of numeral instrument (2), is calculated as through numeral aobvious control instrument (2) that water flow data transfers to PLC controller (3), actual pressure of supply water PV that secondary setting pressure SP and secondary water-supply pressure sensor (6) are recorded compares, adopt the PID closed-loop control, pump speed control device (4) is regulated water pump (5) rotating speed automatically, and one reaches setting pressure equates with actual pressure.
Described exhaust plant is comprised of exhaust manifolds (8) and exhaust trap valve (7), and this exhaust trap valve (7) is only crossed gas but water; Exhaust trap valve (7) places in the little shielded box of control cabinet (12).
Compared with prior art, the beneficial effects of the utility model are: this pipe network pressure-superposed water supply flow controller is an a kind of key device that is specifically designed in the city secondary water-supply equipment (non-negative pressure water-supply installation, pipe network Pressure-superposed water supply equipment), pressure and flow that this device can provide by detecting city planting ductwork, and send pressure and the flow that control signal is controlled the secondary water-supply pump automatically, be equal to or less than the discharge that municipal administration is provided with assurance secondary water-supply flow, thereby avoided the secondary water-supply pump directly to extract the phenomenon of municipal flow.
The exhaust plant of this device is communicated with tank body by water inlet pipe (10), needn't be in the tank upper shed, thus the enhancing airtight performance reduces cost simultaneously.
Description of drawings

Fig. 2 is: the exhaust control device schematic diagram in the pipe network pressure-superposed water supply gas controller
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further details:
During flow control valve work, municipal administration pressure sensor (1) can demonstrate municipal ductwork pressure by the panel embedded type shockproof pressure gage, and this pressure inverting become the 4-20ma signal, send into the aobvious control of numeral instrument (2), numeral aobvious control instrument (2) is by accurate computing, pressure is become flow signal, give PLC controller (3).
PLC controller (3) automatic operation, actual pressure of supply water PV compares in the outlet pipe (11) that secondary setting pressure SP and secondary water-supply pressure sensor (6) are recorded, adopt the PID closed-loop control, pump speed control device (4) is regulated water pump (5) rotating speed automatically, and one reaches setting pressure equates with actual pressure.
When flow control valve detected municipal flow and is lower than the lowest service flow that sets, flow control valve is the set amount of control SP automatically, thereby forced the supply of PV amount to be reduced to below the municipal lowest service flow, avoided to city planting ductwork directly to taking out.
When municipal flow is reset to when normal, perhaps municipal flow is when progressively recovering, and the secondary water-supply flow can progressively promote, and the flow of supplying with when city planting ductwork is during greater than the required maximum stream flow of secondary user, and it is normal that the PV flow can recover.
Exhaust trap valve (7) places in the little shielded box of control cabinet (12), exhaust trap valve (7) connects exhaust manifolds (8), stack enters tank body (9) by tap water water inlet pipe (10), by control realization tank body (9) inside and outside air pressure balance of exhaust trap valve (7).
Claims (2)
1. pipe network pressure-superposed water supply gas controller, formed by flow control device and exhaust plant, it is characterized in that: described flow control device comprises: municipal pressure sensor (1) is connected in the tap water water inlet pipe (10), the aobvious control of municipal administration pressure sensor (1) simultaneous connection word instrument (2), numeral aobvious control instrument (2) connects PLC controller (3), PLC controller (3) connects pump speed control device (4), pump speed control device (4) connects water pump (5), secondary water-supply pressure sensor (6) connects into the secondary water-supply pipe, the aobvious control of secondary water-supply pressure sensor (6) simultaneous connection word instrument (2); Described exhaust plant comprises: exhaust manifolds (8) enter tank body along the tap water water inlet pipe, and exhaust manifolds (8) other end connects exhaust trap valve (7).
