Abstract
The utility model discloses a high pressure pilot electromagnetic valve, which comprises a upper valve body, a lower valve body and a coil valve core component, wherein the lower valve body is provided with a air intake and a discharge hole; upper side of the upper valve body is mounted with a valve core component, characterized in that a block piece is arranged between the upper valve body and the lower valve body; lower end of the block piece blocks the discharge hole tightly through a seal block; also the seal block is provided with a ring hole that communicates with the air intake, the ring hole communicates to a upper cavity of the block piece through a orifice on the block piece; the upper cavity is provided with a compression spring clamping block piece; the upper cavity communicates with a upper cavity of a air faucet of the coil valve core component through a connection hole; and the air faucet communicates with a discharge hole of the lower valve body through a pressure relief hole. Compared with existing products, the products provided in the utility model are is provided with small volume, light weight, convenient mounting maintenance and low cost.
Description
Technical field
The utility model is a kind of high pressure guide electromagnetic valve, belongs to the product structure technical field.
Background technique
On the device of filling combustion gas, the switch of connecting or cutting out the high-pressure gas passage needs very big driving force, its drive unit generally adopts solenoid valve, in order to guarantee enough driving powers, the coil of electromagnetism will design very greatly, has caused the bulky of solenoid valve, in installation process, cause many inconvenience, but also strengthened cost of processing.
Summary of the invention
The purpose of this utility model designs at the deficiency that exists in the existing product just a kind of high pressure guide electromagnetic valve is provided, its objective is by improvement the valve inner pressure channel, reduced requirement, thereby reduced the volume and weight of single unit system solenoid valve power.
The purpose of this utility model realizes by following measure:
This kind high pressure guide electromagnetic valve, comprise upper valve body, following valve body and coil mangetic core assembly, wherein, be processed with inlet hole and discharge orifice on the following valve body, mangetic core assembly is installed on the top of upper valve body, it is characterized in that: at upper valve body, a blocking piece is arranged between the following valve body, the lower end of blocking piece is by the close stifled discharge orifice of sealing seat, also being processed with looping pit on the sealing seat is communicated with inlet hole, looping pit is communicated to the epicoele of blocking piece simultaneously by the throttle orifice on the blocking piece, pressure spring is installed in the epicoele compresses blocking piece, epicoele is communicated with by the epicoele of attachment hole with the valve of coil mangetic core assembly, and valve is communicated with discharge orifice on the following valve body by relief hole.
Technique scheme is by the structure of a leading type is set on the coil spool of solenoid valve, only need with a little electromagnetism input power, just can open the structure of this leading type, and then drive the blocking piece closure of controlling on the main gas distribution channel, reach the purpose that opens or closes main gas distribution channel.Like this, the coil spool of solenoid valve just can design smallerly, and the volume and weight of whole switch valve is reduced.
Description of drawings
Fig. 1 is the overall structure schematic representation of the utility model product
Embodiment
Below with reference to drawings and Examples technical solutions of the utility model are further described:
Shown in accompanying drawing 1, this kind high pressure guide electromagnetic valve, comprise upper valve body 3, following valve body 9 and coil mangetic core assembly 1, wherein, be processed with inlet hole 4 and discharge orifice 6 on the following valve body 9, mangetic core assembly 1 is installed on the top of upper valve body 3, it is characterized in that: at upper valve body 3, a blocking piece 10 is arranged between the following valve body 9, the lower end of blocking piece 10 is by sealing seat 7 close stifled discharge orifices 6, also being processed with looping pit 13 on the sealing seat 7 is communicated with inlet hole 4, looping pit 13 is communicated to the epicoele 14 of blocking piece 10 simultaneously by the throttle orifice on the blocking piece 10 2, pressure spring 11 is installed in the epicoele 14 compresses blocking piece 10, epicoele 14 is communicated with the epicoele of the valve 12 of coil mangetic core assembly 1 by attachment hole 15, and valve 12 is communicated with discharge orifice 6 on the following valve body 9 by relief hole 16, and vent plug 5 is sealed in installation on the discharge orifice 6.
The working procedure of above-mentioned high pressure guide electromagnetic valve is: under the solenoid valve off-position, main gas distribution channel is closed.At this moment, pressurized gas enter by inlet hole 4, and the looping pit 13 on seal washer 8, the sealing seat 7 also enters epicoele 14 by the throttle orifice on the blocking piece 10 2, and compressing blocking piece 10 is sealed on the sealing seat 7; When main gas distribution channel will be opened, the solenoid valve energising, move on the coil mangetic core assembly 1, open valve 12, the epicoele that makes valve 12 is communicated with discharge orifice 6 on the following valve body 9 by relief hole 16, epicoele 14 interior pressure can be released, the pressure difference of formation blocking piece 10 upper/lower terminals by attachment hole 15 rapidly, move on the blocking piece 10, thereby open main gas distribution channel.
The utility model product is compared with existing product has that volume is little, in light weight, installation and maintenance side Just, the low advantage of cost.
