Abstract
An electromagnetic high temperature steam valve relates to the pneumatic actuating component field. The valve is designed aiming at that the prior steam stop valve is unreasonable in structure and design and is difficult to stop the phenomena of running and leakage in long-term operation. The main point of the technology is that a piston component is arranged in a sleeve of a linking sleeve, and the center part is provided with pylomes; cross bores are drilled in the side and are communicated with vertical bores; springs are arranged near the vertical bores and in the concave circle of the piston; when an electromagnetic valve is in normal open, the springs are compressed; a choke plug is embedded in the upper head face of the pylomes of the center part; a plug seat is embedded in the lower head face; a pilot valve core component consists of a tapered valve core milled with an axial rectangular groove by the pilot valve square and a pin valve which can move in the tapered valve core; a backing pin is arranged in the rectangular groove of the tapered valve core. The steam valve with the structure has a small volume and a resistance to high-temperature steam above 300 DEG C, effectively overcomes the phenomena of running and leakage and is suitable for opening or closing the high temperature steam valve frequently.
Description
Affiliated technical field
The utility model relates to the pneumatic apparatus field, is a kind of electromagnetic high-temperature steam valve.
Background technique
At present, the steam valve kind is more, boiler steam stop valve for example, and volume is more greatly, sealability is better when just adorning, but the time one is long, and " race is emitted, leaked " phenomenon of steam just is difficult to stop.Therefore, all valves of working under high temperature, high pressure, explosive condition must have long-term operation and not " race is emitted, leaked ".
Summary of the invention
The utility model proposes a kind of electromagnetic high-temperature steam valve of meter and substitutes old product at the not good enough characteristics of steam valve long-term operation performance.Design proposal is with there is a natural attraction between the sexes after electromagnetism energising power, makes this valve be in opening state; The principle that outage then repels each other with the same sex restores to the original state, and makes this valve be in normally off.Normally off is to head into the chock plug endoporus by needle-valve, and obturating plug is sealed and realized by the hole.This steam valve compact structure, reasonable in design is applicable to the high temperature more than 300 ℃, and market prospects are good.
Description of drawings
Fig. 1 is an electromagnetic high-temperature steam valve structural representation.Sequence number and title among the figure: 1, coil winding assembly, 2, the field core assembly, 3, the pilot valve core assembly, 4, joint sleeve, 5, piston assembly, 6, seal washer, 7, bottom, 8, backing pin, 9, needle-valve, 10, spring, 11, chock plug, 12, vertical core, 13, cross-drilled hole, 14, obturating plug.
Referring now to above schematic representation, its feature is described as follows: a kind of electromagnetic high-temperature steam valve, by the coil winding assembly, the field core assembly, the pilot valve core assembly, joint sleeve, piston assembly, seal washer, compositions such as bottom, the bottom transverse holes is not a clear opening, inlet hole is unimpeded with spending around 90 by the hole, promptly offer inlet hole at an end of bottom, the other end at bottom sets out pore, both center portions are offered by the hole at this, and by inlet hole one side one stifled disjunctor is being set by the hole, the gas that is advanced is blocked by this stifled disjunctor earlier, must enter by the hole around 90 degree, reenter air outlet hole, above the hole, be provided with piston assembly, in the connection place of bottom and joint sleeve, be provided with seal washer and connect by screw.It is characterized in that: in the sleeve of joint sleeve 4, piston assembly 5 is housed, the piston diametric plane of piston assembly is equipped with piston ring, and the center portion is provided with through hole; The side is drilled with cross-drilled hole 13, and what communicate with cross-drilled hole is vertical core 12, is provided with spring 10 at the recessed circle place of vertical core limit, piston.
Pressed chock plug 11 in the embedding of the upper-end surface of center portion through hole, pressed obturating plug 14 in the lower end surface embedding.Pilot valve core assembly 3 is made up of square poppet valve core and an energy movable needle-valve 9 in poppet valve core that is milled with an axial rectangle groove of pilot valve, in the rectangle groove of poppet valve core, be provided with backing pin 8, backing pin is to stop when needle-valve inserts the chock plug endoporus, plays the effect that falls back that stops; Axially rectangle groove is that die for backing pin does not expose and is provided with.Above piston assembly, the poppet valve core external diameter is with spring 10, and it is the recessed circle place that places piston.
Embodiment
The suction port of electromagnetic high-temperature steam valve is to be connected with the pipeline that produces high temperature source one side, and the air outlet is and is connected with the tracheae line that the power line that the coil winding assembly is drawn is connected with power supply.The energising back is by the pole orientation in the control system control field core assembly, and when like pole repelled each other, the poppet valve core of pilot valve core assembly moved down, needle-valve withstands the chock plug endoporus, obturating plug presses air valve by the hole, spring pressurized this moment, and high-temperature gas is cut off in producing high temperature source one side.When there is a natural attraction between the sexes, steam was entered by cross-drilled hole, flowed into the pilot valve core assembly through vertical core.Spring recovers elastic force, moves on the poppet valve core of pilot valve core assembly, and needle-valve breaks away from the chock plug endoporus, and obturating plug is loose by the hole, and the high-temperature gas of generation is to discharging with the gas orientation.Because of poppet valve core is to slide up and down in valve cylinder, piston assembly is to slide up and down in the inner chamber of joint sleeve, thus coaxality can be guaranteed, the unlatching of valve with by also easily realizing.
