Abstract
The invention discloses an electrical heating anti-icing electric control valve. A tower-shaped spring is arranged on a valve rod of the electric control valve through a silicon rubber heating piece. The silicone rubber heating piece is formed by enabling silicone rubber to wrap nickel alloy gold foil or nichrome heating wires. The electrical heating anti-icing electric control valve has the advantages of being efficient in heating performance, long in service life, low in power consumption and anti-freezing, and is suitable for being used as an anti-freezing electric control valve.
Description
Technical field
What the present invention proposed is the anti-freeze electric control valve of a kind of electric heating.
Background technique
Traditional valve rod and the heating equipment between electric actuator generally use heating tape, metal heater plate etc., and its shortcoming is, use heating tape, use the mode be wound around, and not only affect outward appearance, and effectively heating area is little.The METAL HEATING PROCESS plate thickness is difficult to accomplish very thin, and easily by dielectric corrosion.
Summary of the invention
Freeze when preventing electric control valve transporting low temperature medium, the present invention proposes the anti-freeze electric control valve of a kind of electric heating.This modulating valve, by dress turriform spring and silicone rubber heater band on the valve rod of valve body, solves the anti-freeze technical problem of electric control valve.
The scheme that technical solution problem of the present invention adopts is:
By the silicone rubber heater band, the turriform spring is housed on the valve rod of electric control valve.
The silicone rubber heater band consists of silicone rubber parcel nickel alloy foil or nichrome electric heating wire.
Good effect, the anti-freeze electric control valve of electric heating of the present invention has advantages of that heating properties is efficient, long lifetime, low power consumption and antifreeze.Suitable to antifreeze electric control valve application.
The accompanying drawing explanation
Fig. 1 is structural drawing of the present invention
In figure, 1. electric control valve, 2. tower spring, 3. silicone rubber heater band.
Embodiment
According to the figure, by silicone rubber heater band 3, turriform spring 2 is housed on the valve rod of electric control valve 1.
The silicone rubber heater band consists of silicone rubber parcel nickel alloy foil or nichrome electric heating wire.
Effect and characteristics:
The silicone rubber heater band is antifreeze core heating part, electric heating material adopts the nichrome electric heating wire, and isolation layer is be composited by silicone rubber and glass fiber cloth laminar, and minimum thickness can reach 1.5mm, there is good ductility, can with the heating object close contact; Heater element is processed by the Alloy Foil of nickel alloy, and heating power can reach 1.2W/cm
2, heat more even.Like this, just can allow heat be delivered to any required place.
The turriform spring:
Its effect is to make valve rod in the knee-action process, make the silicone rubber heater band tightly fit with gland all the time, guarantees effective heating area.Why spring makes turriform, space when purpose is compresses to greatest extent.Because between valve and final controlling element, space is very limited.
Characteristics of the present invention are:
1, the efficiency of heating surface is high:
Due to the ingenious property of heating equipment of the present invention, the heat that the silicone rubber heater band sends is acted on the valve gap of purpose hot spot all the time, energy arrived sufficient utilization.And heating is fast, temperature is even, and the thermal efficiency is high.
2, water proofing property:
Because heating equipment of the present invention works in the environment of liquid, so the thin slice that silicone rubber and glass fiber cloth are composited has played the effect of waterproof effectively, this is that traditional antifreeze heating equipment of valve can not be accomplished.
3, long lifetime property:
Because the nichrome electric heating wire is to be sealed in silicone rubber, so can or do not corroded by liquid constituent by the ambient air oxidation, so be difficult for agingly, the life-span is extremely long.
4, Security:
Owing to adopting the power supply of AC/DC 24V safety voltage, so guaranteed the Security of on-the-spot electricity consumption.
Claims (1)
1. the anti-freeze electric control valve of electric heating, is characterized in that: on the valve rod of electric control valve (1), by silicone rubber heater band (3), turriform spring (2) is housed;
Described silicone rubber heater band consists of silicone rubber parcel nickel alloy foil or nichrome electric heating wire.
