Abstract
The invention discloses a gas solenoid valve, comprising a U shaped support, a coil support wound with a coil assembly and arranged in the U shaped support, a bushing supporting a platform arranged at upper and lower ends of the U shaped support, a gas track arranged at medial of the bushing, a boss inserting in the bushing arranged bottom of the U shaped support, an iron core for opening or closing the gas arranged in the bushing, a cover plate arranged on the U shaped support, a sealing ring arranged on the boss and a convex rib for installing the sealing part arranged on upper support platform of the bushing. The gas solenoid valve has the advantages of simple structure, convenient installation, low production cost, good safety performance and wide application in the gas stoves and gas water heaters.
Description
Technical field
The present invention relates to a kind of solenoid valve, particularly relate to a kind of gas electromagnetic valve that is used on gas-fired boiler and the gas water-heater.
Background technique
All used solenoid valve on gas-fired boiler and the gas water-heater at present, the electromagnetic force that existing gas electromagnetic valve produces with electromagnetic coil is usually opened or the blocking-up fuel gas path, its structure mainly includes support, frame bottom is installed with fixed core, the fixed core outer seal sleeve is equipped with sleeve pipe, be placed with in the sleeve pipe and can play the moving iron core of opening or closing the combustion gas effect, the complex structure of this product, installation trouble; In addition, can seal fully in order to make solenoid valve, prevent gas leakage, be set with seal ring usually on fixed core and sleeve pipe, and use last sealing iron plate to seal, this mounting type not only bothers, and Security is not high; And, existing moving iron core is the straight-bar structure, the face contact that moving in sleeve pipe just becomes whole cylndrical surface, mobile frictional force is inevitable bigger, in order to reduce the moving resistance of moving iron core, people are cut with grooving usually on the circumferential surface of moving iron core, thereby cause the fabricating cost of product to improve, in sum, existing solenoid valve is difficult to meet people's usage requirement.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of gas electromagnetic valve simple in structure.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of gas electromagnetic valve, it comprises U type support, be provided with the coil brace that is wound with coil groups in the U type support, coil brace is provided with the sleeve pipe of support platform for two ends up and down, described sleeve pipe inboard is provided with air vent, described U type frame bottom is provided with the boss that is inserted in the sleeve pipe, be placed with in institute's sleeve pipe and can play the iron core of opening or closing the combustion gas effect, be coated with cover plate on the described U type support, be set with seal ring on the described boss, the upper support platform of described sleeve pipe is provided with the convex tendon that Sealing is installed;
As a modification of the embodiment above, described coil brace is an injection molding.
As further improvement, install by convex tendon, groove between described U type support and the cover plate and be connected above-mentioned mode of execution.
The invention has the beneficial effects as follows: this product uses the boss on coil brace and the U type support to replace the fixed core and the sleeve pipe of original gas electromagnetic valve, and, be set with the seal ring that is installed between lower support platform and the U type cradle portion on the boss, in addition, convex tendon on the described upper support platform is provided with the Sealing that is installed between upper support platform and the cover plate, goes up the sealing iron plate thereby lacked one than other solenoid valve; And, coil brace adopts the method for injection molding to produce air vent, has reduced the trouble of cutting on the circumferential surface of iron core, and this product structure is simple, easy for installation, fabricating cost is low, Safety performance good, thereby is widely used in the solenoid valve on gas-fired boiler and the gas water-heater.
Description of drawings
The present invention is further described for following accompanying drawing.
Fig. 1 is a structure broken away view of the present invention.
Embodiment
With reference to Fig. 1, a kind of gas electromagnetic valve, it comprises U type support 1, be provided with the coil brace 2 that is wound with coil groups in the U type support 1, coil brace 2 is that two ends are provided with support platform 21 up and down, 22 sleeve pipe 23, described coil brace 2 is an injection molding, so make simple, and when making, this product is in order to reduce the mobile resistance of air of iron core 5 in sleeve pipe 23, described sleeve pipe 23 inboards are provided with air vent 25, the use of air vent 25, effectively reduced the trouble of on the circumferential surface of iron core, cutting, described U type support 1 bottom is provided with the boss 11 that is inserted in the sleeve pipe 23, the use of boss 11 has replaced the fixed core of original gas electromagnetic valve, play the effect of fixed coil support 2, be placed with in institute's sleeve pipe 23 and can play the iron core 5 of opening or closing the combustion gas effect, be coated with cover plate 6 on the described U type support 1, in addition, between described U type support 1 and the cover plate 6 by convex tendon 12, groove 61 is installed and is connected, so install very conveniently, this product uses coil brace 2 to replace the sleeve pipe of original gas electromagnetic valve and goes up the sealing iron plate, thereby it is simple to reach product structure, characteristics easy for installation, that fabricating cost is low.
In addition, this product is set with seal ring 7 on described boss 11, seal ring 7 is installed between lower support platform 22 and U type support 1 bottom, the upper support platform 21 of described sleeve pipe 23 is provided with the convex tendon 24 that Sealing 8 is installed, Sealing 8 is installed between upper support platform 21 and the cover plate 6, this design makes this product lack one than other solenoid valve and goes up the sealing iron plate that this design is not only installed simply, need not be increased miscellaneous part, and safe.
This product structure is simple, easy for installation, and fabricating cost is low, Safety performance good, thereby is widely used in the solenoid valve on gas-fired boiler and the gas water-heater.
