Abstract
The utility model discloses a kind of combustion gas form item ring structure, the sealing ring is enclosed in the rotating shaft in diaphragm gas meter valve body, the rotating shaft realizes linear sealing by sealing ring, and the section of the sealing ring is W shapes, and the sealing ring top of W shapes is 2 grooves.Combustion gas form item ring structure provided by the utility model, sealing ring is designed to specific lipped configuration, the position of sealing ring installation, top is influenceed by gas pressure outside movement, lower section is influenceed by pressure in movement, movement internal pressure promotes the operating of rotating shaft, has had resulted in pressure loss because of the flowing by table body.Therefore internal pressure is less than external pressure.The sealing effectiveness of W type sealing rings is more preferably.
Description
Technical field
The utility model relates to gas meter, flow meter technical field, and in particular to a kind of combustion gas form item ring structure.
Background technology
At present, domestic and international diaphragm gas meter is by volume metering, and diaphragm gas meter belongs to a kind of displacement machine instrument
Table, metering system is formed by two containers (batch meter).Table internal rubber seal part also takes on important effect.Such as in table
Rubber parts is applied in internal rotation shaft member.Common rubber parts often rotates the original with combustion gas per se with gaseous impurity because of axle class
Cause, the influence of abrasion and swelling is had to rubber parts in itself, and rubber parts swelling can cause the resistance increase that table is run, influence to measure
And service life.The problem of for this respect, utility model application scheme propose a kind of combustion gas form item ring structure.
Utility model content
The utility model is to provide a kind of combustion gas form item sealing to solve the technical scheme that above-mentioned technical problem uses
Coil structures, sealing ring design structure it is reasonable, the particularity of sulfuration process greatly reduces swelling of the gaseous impurity to rubber parts
Influence, wherein, concrete structure is：
The sealing ring is enclosed in the rotating shaft in diaphragm gas meter valve body, and the rotating shaft is realized linear by sealing ring
Sealing, the section of the sealing ring is W shapes, and the sealing ring top of W shapes is 2 grooves.
The utility model has the advantages that relative to prior art：
Sealing ring is designed to specific lipped configuration, and with reference to the accompanying drawings shown in 2, the position of sealing ring installation, top is by table
The influence of outer gas pressure, lower section are influenceed by pressure in table, and pressure below promotes the fortune of rotating shaft because of the flowing by table body
Turn, had resulted in pressure loss.Therefore top pressure is more than the pressure in the cavity that lower section is subject to.Seal up pressure
Under the influence of, appropriate deformation, form more structurally sound seal line.Rotating shaft is almost linear sealing, reduces the mill to seal
Damage.
Brief description of the drawings
Fig. 1 is the schematic diagram of combustion gas form item ring structure.
Fig. 2 is the use state figure of combustion gas form item ring structure.
In figure：
The rotating shaft of 1 sealing ring 2
Embodiment
The utility model will be further described with reference to the accompanying drawings and examples.
Diaphragm gas meter is a kind of volumetric metering instrument, has many rubber sealing elements inside gas meter, flow meter, undertakes various
Sealing between component.Dynamic sealing for rotary part, such as various axles, on the premise of ensureing to seal, control again produces
Resistance, to ensure to obtain higher sensitivity.Diaphragm gas meter rubber parts generally existing timeliness solvent swelling state in industry, performance
To be lengthened with usage time, the increase of gas meter, flow meter running resistance, inner sealing is bad constantly to be aggravated.How sealing is solved
The key of table service life and product performance control is to determine with running resistance increase caused by the swelling of rubber parts.
Referring to the drawings 1, present embodiment uses following technical scheme：
In structure, sealing ring 1 is designed to specific W shapes structure, with reference to the accompanying drawings shown in 2, the position of the installation of sealing ring 1, on
Side is influenceed by off-balancesheet gas pressure, and lower section is influenceed by pressure in table, and pressure below promotes because of the flowing by table body
The operating of rotating shaft 2, has had resulted in pressure loss.Therefore, top pressure is more than the pressure in the cavity that lower section is subject to.Sealing ring
1 up under the influence of pressure, appropriate deformation, forms more structurally sound seal line.Rotating shaft 2 is almost linear sealing, reduces
Abrasion to sealing ring 1.
The design structure of sealing ring 1 is reasonable, and reducing swelling of the gaseous impurity on rubber parts influences.For cross-linked polymer with
And for the line polymer in poor solvent, untill swelling can only be carried out to a certain extent, contacted later with solvent
How long, the amount for sucking solvent is not further added by, and reaches balance, and system remains two-phase state.
In summary, by the application of this single file sealing ring, reduce the abrasion of sealing ring 1 and be swelled to mechanically operated
Influence.Ensure gauging of products precisely and product service life.Reasonable in design, installation is simple, easy to use, improves common
Abrasion of the sealing ring in abrasion gas meter, flow meter application, the drawback such as swelling, and the normal operation of diaphragm gas meter is not influenceed, improve
The reliability of product.In addition, security performance improves, prevent from collaborating between gas meter, flow meter internal cavity, measuring accuracy improves.
Although the utility model is disclosed as above with preferred embodiment, so it is not limited to the utility model, any
Those skilled in the art, do not departing from spirit and scope of the present utility model, when a little modification and perfect, therefore this can be made
The protection domain of utility model is worked as to be defined by what claims were defined.
