Description
Technical field
The present invention relates to a kind of self-powering type antifreezing valve, belong to valve automatic control technology field.
Background technique
The self-powering type antifreezing valve is a kind of water delivery, antifreeze valves of water storage system such as hydraulic system, pipeline, container of being used for; Be widely used in industrial and agricultural production and the daily life; As: solar water heater heat exchanger and upper and lower conduit road thereof, town and country tap water water delivery, water system, irrigation system, waterworks for firefighting, harbour; The public engineer system of the water charging system of railway etc., oil, chemical industry, smelting etc., the pipeline of special vehicles such as train, fire-fighting, watering, water tank and equipment etc. antifreeze.
One of important method that water deliverys such as hydraulic system, pipeline, container, water storage system are antifreeze is exactly that the self-powering type antifreezing valve is installed in system; Before water-ice freezes; Frost valve is opened valve automatically according to setting temperature, bleeds off low temperature water to reach the antifreeze purpose of system.Therefore the negotiability of frost valve has determined the size that frost valve institute can protective system, and frost valve negotiability deficiency will directly cause anti-frost protection to be failed.
The self-powering type antifreezing valve generally comprises valve body; This valve body has the entery and delivery port that can be connected to water system; Temp-sensitive apparatus, location in temp-sensitive apparatus slide member and the valve body on the same axis and return assembly interact, and drive spool opening and closing valve according to setting temperature.
In the tradition self-powering type antifreezing valve, return spring is looped around between the spool outside and the valve port.Under the certain condition of body cavity radial dimension, limited the diameter of spool and gasket seal, thereby limited the negotiability of valve.
Tradition self-powering type frost valve is according to the temperature opening/shutting valve of the medium (water) of perception; The temperature-sensitive of temp-sensitive apparatus is partly far away from the valve opening and closing port; When frost valve intermittently opened and closed, there were big temperature gradient in the medium of temp-sensitive apparatus perception (water) temperature and valve port medium (water) temperature.When ambient temperature during far below the freezing point (0 ° of C) of medium (water), the medium that valve port retains (water droplet) freezes rapidly, and valve port is frozen in before valve is opened next time easily, and frost valve was lost efficacy, and valve takes place freeze stifled accident.
Summary of the invention
The purpose of this invention is to provide a kind of self-powering type antifreezing valve,, under the certain condition of valve body internal diameter, improve the negotiability of valve through the special construction of valve opening part.
Another object of the present invention is to improve the antifreeze ability of frost valve, reduces frost valve and under low temperature environment, freezes stifled possibility.
Technological scheme of the present invention realizes like this:
Valve by an end can be connected to the valve tube fitting of hydraulic pressure and/or storage of water system, the valve body that is connected through thread seal with the valve tube fitting, the temp-sensitive apparatus of body cavity setting, the positioning component that is positioned at valve tube fitting one end, the return assembly that is positioned at the valve opening and closing end etc. form; Be positioned in a movable manner assembly, return assembly of temp-sensitive apparatus is supported on valve cavity; The telescopic push rod of temp-sensitive apparatus is near valve tube fitting end; The temperature-sensitive end of temp-sensitive apparatus is near the valve opening and closing end; Positioning component comprises cup-shaped locating piece, guiding device and retaining spring, and retaining spring acts on the said valve tube fitting and through guiding device and acts on the cup-shaped locating piece, and movably push rod of temp-sensitive apparatus is withstood in cup-shaped locating piece bottom; The return assembly is made up of cup-shaped carriage, return spring, spool and embedding gasket seal wherein; The temperature-sensitive end of temp-sensitive apparatus withstands spool through cup-shaped carriage, and back-up ring is passed at the connection position of cup-shaped carriage and spool, and return spring acts on back-up ring and the cup-shaped carriage; When the temperature of temp-sensitive apparatus perception when higher set temperature (like 6 ° of C); The temperature sensing material structure expands, and the temp-sensitive apparatus push rod stretches out, thereby drives spool and valve opening and closing end formation sealing throttle down; When the temperature of temp-sensitive apparatus perception during at low setting temperature (like 3 ° of C), the temperature sensing material structure is shunk, and the temp-sensitive apparatus push rod shrinks in temp-sensitive apparatus, leaves the valve opening and closing end and opens valve thereby drive spool.
The invention has the beneficial effects as follows:
The special construction of valve opening and closing part has been eliminated the flow bottleneck of valve, under the certain situation of valve cavity radial dimension, has significantly improved the negotiability of valve;
The temperature-sensitive part of temp-sensitive apparatus has significantly reduced the medium temperature of temp-sensitive apparatus perception when frost valve intermittently opens and closes and the temperature gradient between valve opening and closing end medium temperature near the valve opening and closing end, makes the valve opening and closing end be difficult for being frozen in, and has effectively improved the antifreeze ability of valve.
