Abstract

The utility model discloses an automatic valve for a water intake of a water tank. The utility model comprises an automatic device and a valve, wherein, the automatic device is mainly composed of a mainspring, a mainspring wheel, a transmission mechanism, a control shifting fork, a pressure gauge of return water, an upper clamp plate, a lower clamp plat, a connecting part, a spring, a pipe clamp, a casing, etc. Whether the mainspring wheel of the automatic device is rotated is controlled through a shifting fork, a ratchet wheel and a transmission wheel by using stored return water as a pressure power source; the utility model can be widely used for water intake of a solar water heater tank through the combination of a mainspring wheel and an ordinary switch valve of 90 DEG of a knob. When the water level reaches a limited standard value, the return water flows into the pressure gauge, and the button-control knob automatically rotates back to close the valve; when the valve is opened again, the shifting fork is in an off position, and the automatic device is in the ready state. The use method is the same as the use method of an ordinary on-off valve of 90 DEG of a knob, and just the knob is counterclockwise rotated in 90 DEG. The utility model has the characteristics of safety, practicality, convenient operation, low cost, strong durability, etc.

Description

Water automatic water stopping device on the water tank

The utility model relates to a kind of control valve unit, particularly relates to water automatic water stopping device on a kind of water tank of solar energy water heater special water-feeding system.

At present, the water supply valve door of public place use has gate valve, stop valve, ball valve and float valve etc.Have minority to use solenoid valve, most prison water devices all do not adopt the automatic counter measure of spilling water sealing, by labor management and operation, very easily cause water resource waste.With solenoid valve also be restriction and the influence that usually is subjected to factors such as safety, power consumption, outage, electric shock, relevance factor and reliability are low, be difficult for to be extensive use of, social efficiency is low, and is not popular with users.

The objective of the invention is defective at above-mentioned prior art existence, a kind of waste that can avoid water resources effectively is provided, can overcome the corrosion of valves such as gate valve, stop valve and ball valve and shortcoming such as depoling is out of control, can overcome the restriction of factors such as solenoid valve power consumption, outage, electric shock and the utilization rate and the reliability height of influence, social efficiency is good, cost is low, can be extensive use of water automatic water stopping device on the water tank very popular with users.

For achieving the above object, the utility model provides water automatic water stopping device on a kind of water tank.It mainly comprises automation and valve two-part composition, automation forms according to clockwork spring moment of elasticity button power and gear transmission principle design, and it mainly is made up of clockwork spring, bar wheel, driving mechanism, control shift fork, pressure of return water device, last die holder, link, spring, pipe clamp and shell etc.Clockwork spring rolls with the thick stainless steel sheets of 0.5-1mm and forms, on bar wheel wheel shaft, switching knob is equipped with in bar wheel wheel shaft upper end, a part extends to outside the gear die holder below the bar wheel wheel shaft of clockwork spring with being equipped with, design one with the selected equally square interface of valve knob crown of roll, make then one round outside but spuare inside, bar wheel shaft and valve can be revolved a link that links together, bar wheel shaft and valve knob axle are connected as a single entity, it can coaxially be moved together.It links to each other with the valve crown of roll is coaxial with link.Driving mechanism is made up of the bar wheel some, is fixed on asking of die holder together with bar wheel shaft, shift fork etc.Valve can be selected the common 90 degree switch valves that revolve for use, also valve shaft and link can be designed to one (only needing to change valve shaft).Design has a control shift fork on the ratchet of transmission system terminal, control shift fork one end is used for pinning and opening ratchet, be stressed switch control of the other end, be responsible for the open mode of ratchet, spring is housed on the declutch shift shaft, shift fork is produced pin the cloudy power that ratchet rotates, shift fork one end that the control ratchet rotates is controlled the control fork that ratchet rotates under acting force of the spring, the other end is arc interface, links to each other with the pressure of return water device.Whether the pressure of return water device has backwater control shift fork that the switch of ratchet is rotated counterclockwise knob 90 degree on the automation according to return pipe, and robot device is set valve and is also opened synchronously.When clockwork spring is installed for strengthening button power, can be earlier with the clockwork spring button to the limit, return then about 180 degree, again a valve to " passs " is installed and fixed with link and automation, connect return pipe.

The advantage of water automatic water stopping device is on the utility model water tank: owing to adopt the machine power principle, have safe and reliable, easy to operate, be not subjected to the external environment effects limit, low cost of manufacture, relevance factor height, the social efficiency height, be widely used on the feedwater return water system of solar energy bathing pool, using water wisely effectively is subjected to users' welcome very much.

Below in conjunction with accompanying drawing the utility model is done detailed explanation.
