Description
Technical Field
The utility model belongs to a little consumption remote control relief pressure valve, especially a little consumption remote control relief pressure valve based on pipe network dynamic balance. The pressure reducing valve relates to the automatic control technology of valves in a pipe network, and is particularly suitable for a voltage stabilizing control valve in an area with inconvenient power supply.
Background
At present, a mode of adding a controller to an electric regulating valve is generally adopted for controlling a pressure stabilizing valve in a pipeline, and a control mode of a pilot type pressure reducing valve is generally adopted in the industry in a field area which cannot provide power electricity for the valve. The pilot type pressure reducing valve has certain disadvantages that when the rear pressure stabilizing value of the valve needs to be adjusted, a worker needs to go to the position where the valve is installed and manually adjust the pilot valve on the valve body to achieve the purpose of improving or reducing the rear pressure stabilizing value of the valve. This greatly reduces the work efficiency and also increases the running cost.
SUMMERY OF THE UTILITY MODEL
In order to realize the control problem of the pressure stabilizing valve in the power electricity region without power supply, save the electric energy consumption and realize the remote real-time detection and control of the valve, the utility model uses the small-pipe diameter flow regulating technology to realize the continuous adjustment of the pressure stabilizing value of the valve; and the low-power-consumption controller is used for adjusting the flow valve so as to achieve the purpose of adjusting the post-regulation pressure value of the valve and exchanging information with the remote monitoring station.
The utility model discloses it connects to pass through into conduit (2), ball valve (1) to the valve central control room to intake the side at Y type sleeve valve, goes out the water side and also is connected with the central control room through play water pipe (7), play water sample ball valve (8), flow valve (6) to it also communicates with each other through the pipe valve (sees the valve structure picture) to intake the water side. The flow valve (6) and the outlet pressure detection (9) are connected to the controller through signal lines, the controller obtains a pressure value instruction sent by the remote monitoring station through GPRS, and meanwhile, a valve back pressure real-time value is transmitted to the remote monitoring station.

Detailed Description
Valve state change implementation (see valve structure diagram and logic block diagram)
And (3) equilibrium state: the water inlet pressure P1 enters the main valve control chamber (14) through the water inlet conduit (2) and the ball valve (1), and the water in the main valve control chamber (14) is discharged to the water outlet side of the valve through the water outlet conduit (7), the flow valve (6) and the water outlet sampling ball valve (8). At equilibrium the water intake in the control chamber equals the displacement and creates a downward pressure F1 on the piston. The downward pressure F1 and the upward force of the inlet water acting on the main valve piston (12) and the force of the main valve spring (16) are balanced, and the valve is in a static balance state.
Boosting operation: when the valve back pressure value P2 is lower than the set value P (the reason may be that the valve back pressure value is reduced due to the increase of water consumption and the set value is increased), the opening degree of the flow valve (6) is increased by the controller, the water discharge amount in the main valve control chamber (14) is increased, and the water amount in the control chamber is reduced. The downward pressure F1 is reduced, the main valve piston (12) moves upward, the valve opening is increased, the valve outlet pressure is increased, and when the valve pressure is equal to the set pressure (the deviation is not more than +/-5%, and can be set according to actual conditions), the balance is adjusted to a new balance.
And (3) pressure reduction operation: when the pressure value P2 is higher than the set value P (the reason may be that the water consumption is reduced to increase the pressure value P, the set value is reduced), the opening of the flow valve (6) is reduced by the controller, the water discharge in the main valve control chamber (14) is reduced, the water quantity in the control chamber is increased, the downward pressure F1 is increased, the main valve piston (12) moves downward, the valve opening is reduced, the valve water outlet pressure is reduced, and when the pressure value P2 is the same as the set pressure (the deviation is not more than +/-5%, the set value can be set according to the actual situation), the balance is adjusted to a new one.
Implementation of remote control (see control schematic)
The low-power controller is arranged near the valve, and the functions of the low-power controller are mainly two: 1. and receiving a pressure signal behind the valve, and adjusting the flow valve according to the pressure set value to achieve the aim of stabilizing the pressure behind the valve at the set value. 2. And transmitting the pressure signal after the valve to a remote station and a mobile phone client in a wireless mode, and receiving pressure set value instructions of the remote station and the mobile phone client.
Due to the fact that the power supply on the site side is inconvenient and the like, the controller is powered by a solar panel and a storage battery, and a low-power controller is selected, so that the purpose of convenient and stable control is achieved.
