Description
Technical Field
The invention relates to a control water tank in a secondary water supply system, in particular to a control water tank with double-liquid-level water inlet and supplementing functions.
Background
The water tank in the secondary water supply system is filled with water, at present, a remote control float valve is mostly adopted for constant liquid level control, and the defect that when the liquid level of the water tank fluctuates up and down near the constant liquid level, a remote control float ball guide valve is in the opening and closing continuous switching process, on one hand, the sealing surface of the float ball guide valve is rapidly worn, on the other hand, the service life of the main valve is seriously influenced by frequent opening and closing of the main valve, and the problem becomes the acknowledged problem of the water tank.
Although there are various schemes for achieving dual level control (water inlet is turned off when the tank level is high and water inlet is started at a relatively low level), such as: the electromagnetic valve and the floating ball remote control pilot valve are adopted to realize double liquid level control, but the liquid level needs to be detected, and power supply and electrical control are needed; the electric valve of the water inlet main pipeline can also realize double-liquid-level control, but the cost is high and the reliability is doubtful; there is also a specially designed vertical double-level floating ball remote control valve, but its floating ball pilot valve structure and installation mode are complex.
In a word, the water inlet of the water tank is ideally controlled by double liquid levels, so that frequent opening and closing of a control valve can be avoided, the service life is prolonged, the fresh flow of the inlet and outlet circulation of water stored in the water tank is particularly facilitated, and the double liquid level control device is not generally applied to the water tank due to the technical cost.

Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below by combining the specific drawings.
Referring to fig. 1, the invention discloses a control water tank with double liquid level water inlet and replenishing functions, which comprises a large water tank 10 and a small water tank 20 arranged on the upper part of the large water tank 10, wherein the small water tank 20 is arranged above a high liquid level waterline 11 of the large water tank 10, and the top of the small water tank 20 is communicated with the large water tank 10 through an overflow pipe 21; the control water tank further includes a hydraulic remote-control main valve 30, a liquid level control valve 40, and a three-way switching valve 50 provided on a water supply line connected to the large water tank 10; a water inlet, a water outlet and a liquid level sensing pipe 41 are arranged on the liquid level control valve 40, the water inlet of the liquid level control valve 40 is connected with a remote control interface of the hydraulic remote control main valve 30 through a remote control connecting pipe 31, and the water outlet of the liquid level control valve 40 is connected with the large water tank 10 through a pipeline; the three-way switching valve 50 comprises a port A, a port B and a port C, the port A of the three-way switching valve is connected with a water outlet pipeline of the hydraulic remote control main valve 30, the port B of the three-way switching valve is connected with a liquid level sensing pipe 41 of a liquid level control valve 40, the port C of the three-way switching valve is connected with the bottom of the small water tank 20, the port B of the three-way switching valve is also connected with the large water tank, and a flow regulating valve 60 is arranged between the port A and the large water tank.
The working principle of the invention is as follows:
when the hydraulic remote control water replenishing device is used for the first time, as the large water tank 10 is not filled with water and is at the lowest liquid level, the liquid level control valve 40 is in an opening state, the hydraulic remote control main valve 30 is also in an opening state, and water is replenished into the large water tank 10; when the liquid level control valve 40 and the hydraulic remote-control main valve 30 are opened, water flows to open the internal valve flap of the three-way switching valve 50 and flows from the port A to the port C (simultaneously blocks the port B), the small water tank 20 starts to be filled with water, and the filling is continued when the water reaches the high liquid level of the small water tank (the overflow state has no other influence).
When water is supplied to the large water tank 10 until the high liquid level waterline 11, the liquid level control valve 40 is closed, then the hydraulic remote control main valve 30 is also closed, and the large water tank 10 stops supplying water; meanwhile, the valve flap inside the three-way switching valve 50 is restored (the port A is blocked, and the port B is communicated with the port C), the small water tank 20 is stopped from being filled with water, water begins to flow out, and the water flow flows from the port C to the port B of the three-way switching valve 50 and then to the liquid level sensing pipe 41.
When the small tank 20 is drained, the liquid level sensing pipe 41 will always detect a high liquid level (not the actual high liquid level of the large tank), so that the liquid level control valve and the hydraulic remote control main valve 30 always keep a closed state.
The outlet water of the small tank 20 needs a certain time t from its own high level to its own low level, and the time t = V0/q is determined by the small tank volume V0 and the outlet water flow rate q, and the outlet water time t determines the position of the lower limit point of the liquid level of the double-level control of the large tank, and the outlet water flow rate q can be changed by the flow regulating valve 60.
Referring to fig. 2, when the volume of the water tank is small and the required water inflow is small, the hydraulic remote control main valve may be omitted, or the above-described principle scheme may be adopted to implement dual-level control, which is not described herein.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
