Abstract
The utility model relates to an automatic shutdown protection apparatus for pipe network pipe burst decompression, comprising a liquid level switch connected to a pool through communication cables, a water pump, a telemetering pressure gauge, an electric contact pressure gauge, a frequency conversion control cabinet, a feed pipe network, and a tap water pipe network, and is characterized in that: a pool is provided with the liquid level switch which is in connection with the frequency conversion control cabinet through transmission lines; an inlet pipe of the water pump is in connection with the pool, and an outlet pipe of the water pump is in connection with the feed pipe network; both of the inlet pipe and the outlet pipe are equipped with a gate valve; the telemetering pressure gauge and the electric contact pressure gauge are in bypass connection between the outlet pipe of the water pump and the feed pipe network; and the water pump, the telemetering pressure gauge and the electric contact pressure gauge are respectively in connection with the control cabinet through transmission lines. The automatic shutdown protection apparatus for pipe network pipe burst decompression of the utility model has the advantages that when the electric contact pressure gauge detects ultralow pressure and feeds back a ultralow pressure signal to the control cabinet; and if at the moment all pumps are in an operation state and pipelines still feed back ultralow pressure, then pipe network pipe burst decompression is determined and control system power supply is immediately cut off to realize automatic shutdown protection.
Description
Technical field
The utility model relates to a kind of device because of pipe network booster decompression automatic shutdown protection.
Background technology
The water system of the residential building in present many cities has all adopted constant pressure water supply system, realize that auto state keeps water pressure invariableness to satisfy the water requirement when water supply volume changes, but under the situation that runs into pipe network booster decompression, in time do not feed back signal to control system, cause reliability of system operation and safety to reduce greatly.
Summary of the invention
The purpose of this utility model is to solve the unshielded integrity problem of pipe network booster decompression in the prior art, and a kind of device because of pipe network booster decompression automatic shutdown protection is provided.A kind of device of design of the present utility model because of pipe network booster decompression automatic shutdown protection, comprise the liquid-level switch, water pump, the teletransmission pressure meter that are connected to the pond by communication cable, electro connecting pressure gauge, variable frequency control cabinet, water supply network, tap water pipe network, it is characterized in that: be provided with liquid-level switch in the pond, liquid-level switch is connected with switch board by transmission line; The water inlet pipe of water pump connects the pond, the outlet pipe of water pump connects water supply network, the inlet tube and outlet tube of water pump is by gate valve is housed, other connecing detected teletransmission pressure meter and electro connecting pressure gauge between the outlet pipe of water pump and the water supply network, and water pump, teletransmission pressure meter, electro connecting pressure gauge are connected with switch board by transmission line respectively.The utility model has the advantages that when electro connecting pressure gauge detects ultralow pressure, with the ultralow pressure signal feedback in switch board, if this moment all pumps all be in running status; pipeline still feeds back ultralow pressure; then judge it is pipe network booster decompression, cut off the control system power supply immediately, automatic shutdown protection.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
A kind of device among the figure because of pipe network booster decompression automatic shutdown protection, comprise the liquid-level switch 2, water pump 3, the teletransmission pressure meter 4 that are connected to pond 1 by communication cable, electro connecting pressure gauge 5, variable frequency control cabinet 6, water supply network 7, tap water pipe network 8, it is characterized in that: be provided with liquid-level switch in the pond, liquid-level switch is connected with the variable frequency control cabinet by transmission line; The water inlet pipe of water pump connects the pond, the outlet pipe of water pump connects water supply network, the inlet tube and outlet tube of water pump is by gate valve 9 is housed, other connecing detected teletransmission pressure meter and electro connecting pressure gauge between the outlet pipe of water pump and the water supply network, and water pump, teletransmission pressure meter, electro connecting pressure gauge are connected with switch board by transmission line respectively.
Set up an electro connecting pressure gauge at the outlet pipe place of water pump, in time fed back ductwork pressure, judged whether booster, thereby reached the effect of automatic shutdown protection in conjunction with control system.
