Description
Technical field
The utility model relates to valve technology field, especially a kind of rock gas solenoid valve.
Background technique
In line transportation, need on pipeline, be connected in series valve, in recent years,, and have rapid and convenient, advantage such as remote controlled along with the fast development of solenoid valve, the application of solenoid valve in pipeline increases gradually; But, in the bigger pipeline of some calibers is carried, as natural gas transport etc., because the flow in the pipeline is relatively large, and existing solenoid valve mostly is single armature, in use, and moving a conducting or disconnecting delivery line by armature, because the latus rectum of pipeline is bigger, when armature was once opened all pipelines, flow moment sharply increased, and cause enormous impact so just can for flow monitoring equipment, when serious, even can damage monitoring equipment.
Summary of the invention
The purpose of this utility model is to provide a kind of rock gas solenoid valve, to solve the problem of existing solenoid valve severe impact flow monitoring equipment when opening.
In order to address the above problem, rock gas solenoid valve of the present utility model is by the following technical solutions: the rock gas solenoid valve, comprise valve body, described valve body comprises inducer and outlet section, described inducer and outlet section cut off by the dividing plate that is arranged between the two, the outer periphery of valve body is equipped with at least two valve passages, corresponding described valve passage place is provided with and is used to cut off or the mangetic core assembly of the corresponding valve passage of conducting on the valve body, and described mangetic core assembly comprises armature, cover at the guide sleeve of described armature outside, be located in the coil of described guide sleeve periphery and be mounted on guide sleeve and armature between Returnning spring.
The outer periphery of described valve body is equipped with main valve passage and secondary valve passage, and described main valve passage comprises first through hole that communicates with described inducer and second through hole that communicates with described outlet section; Secondary valve passage comprises third through-hole that communicates with inducer and the fourth hole that communicates with outlet section; The outer cup of described main valve passage is provided with valve gap, be provided with flap in the valve gap, valve gap is tightly connected with the guide sleeve of corresponding mangetic core assembly, flap connects with the armature of corresponding mangetic core assembly away from an end of valve body, flap seals at least one in described first, second through hole under the off-position of the coil of the mangetic core assembly of correspondence, the 3rd, in the fourth hole at least one under the off-position of corresponding mangetic core assembly by corresponding armature sealing.
The guide sleeve of the mangetic core assembly of secondary valve passage correspondence is covered with secondary valve passage and is threaded in valve body; Valve gap is connected by bolt with valve body, and the guide sleeve of the mangetic core assembly of main valve passage correspondence is threaded with the side of valve gap away from valve body.
Has the annular groove that communicates with described first through hole in the scope being covered with of valve gap around described second through hole.
Described flap connects by spring with the armature of corresponding mangetic core assembly, have respectively balance inlet hole, balance exhaust port that the inlet/outlet with described valve body connects on the flap, described balance inlet and outlet hole connects the both ends of the surface of flap, and the balance exhaust port seals by corresponding armature under the off-position of the coil of corresponding mangetic core assembly.
The endoporus of the guide sleeve of described each mangetic core assembly is a step hole, the armature slidable fit is in the path hole of the step hole of guide sleeve, armature has the retaining edge near an end of the opening of corresponding guide sleeve, and the Returnning spring of the mangetic core assembly of described secondary valve passage correspondence is mounted between the step surface of corresponding armature and guide sleeve; The Returnning spring of the mangetic core assembly of main valve passage correspondence is mounted between corresponding armature and the inner side surface of corresponding guide sleeve away from an end of valve body.
Described flap has flap retaining edge away from an end of valve body, and flap articulates by spring with corresponding armature.
Because rock gas solenoid valve of the present utility model cuts off its inducer and outlet section by dividing plate, and upwards be arranged to few two valve passages week, corresponding mangetic core assembly is set on each valve passage controls the folding of corresponding valve passage, thereby can progressively open each bar valve passage, flow in the transmission pipeline is progressively added up, avoid because of once fully conducting valve body inducer and outlet section cause flow to be uprushed, and then prevent because of the delivery line flow severe impact monitoring equipment of uprushing.
Further, described valve passage is divided into major and minor valve passage, and at described main valve passage place flap is set, the armature by correspondence drives the folding that flap is controlled the main valve passage, like this can be under the constant prerequisite of the radial dimension that keeps corresponding armature suitable expansion main valve passage; The guide sleeve of the mangetic core assembly of secondary valve passage correspondence is covered with secondary valve passage and is spirally connected with valve body, help being sealed and matched between the guide sleeve of valve body and corresponding mangetic core assembly like this, prevent gas leakage, the guide sleeve and the valve gap of the mangetic core assembly of main valve passage correspondence are spirally connected simultaneously, also are for the ease of sealing; Described flap connects by spring with the armature of corresponding mangetic core assembly, balance is set on flap to be advanced, relief opening, like this can be when secondary valve passage be at first opened, guarantee pressure balance between the flap both ends of the surface by the balance inlet hole that communicates with described annular groove, avoid flap being backed down because of valve outlet place pressure is excessive, when needs are opened the main valve passage, corresponding armature moves and opens balance exhaust port (owing to being to flexibly connect by spring), by the balance exhaust port flap is discharged with the pneumatosis between the corresponding guide sleeve, and then drive flap and move, thereby open the main valve passage; In the armature corresponding end retaining edge is set, Returnning spring can be mounted between described step surface and the described retaining edge, be convenient to the dismounting and change spring; Flap is continued to use spring by its flap retaining and is articulated with corresponding armature, makes things convenient for connection like this and dismantles.
