Description
Technical field
The utility model belongs to filter technical field, and in particular to a kind of filtering of Horizontal type natural gas separator-filter
Cylinder nozzle sealing device.
Background technology
Due to, containing solid particle polluter and micro liquid, therefore generally matching somebody with somebody in natural gas on natural gas transportation pipeline
If filter, the natural gas after being filtered could meet pure requirement, otherwise can influence using effect, more precisely
Combustion efficiency is influenceed, such as when natural gas is as the civilian burning energy, if purity level is short of, then easily cause gas utensil
Blocking and carbon deposit etc., and when commercial Application, then there is the anxiety for undermining burner.
Natural gas filter has vertical and horizontal two kinds, vertical natural gas filter such as Chinese patent CN2513654Y（My god
Right air filter）、CN2621795Y（Multifunctional gas filter）、CN2743014Y（Fast opening type pipe line filter）、
CN2787288Y（Natural gas precise filter）And CN100535501C（Natural gas filter）, etc..Vertical natural gas is filtered
Device has the small strong point of i.e. floor space that occupies little space for Horizontal natural gas filter, but inspection is for example changed
Filtration core etc. is more bothered, and Horizontal natural gas filter is thought highly of compared with by industry in view of this, the skill on Horizontal natural gas filter
Art information can be equally seen in disclosed Chinese patent literature, such as CN2474207Y（Cartridge type natural gas, ＜ coal gas ＞ filters）、
CN201040223Y（Natural gas mercury-removing filter）、CN201394401Y（A kind of natural gas filter）、CN102559314B（It is sleeping
Formula natural gas filter）, CN104056503B（Multipurpose horizontal natural gas separator-filter）、CN104056504B（It is safety-type
Horizontal type natural gas separator-filter）And CN104056507B（Horizontal type natural gas separator-filter）Etc..
Whether vertical or Horizontal natural gas filter is respectively provided with cartridge filter nozzle sealing device, works as natural gas filter
Using for example foundation is connected to the pressure difference changing condition on the pipeline of inlet, outlet interface after a period of time（Pressure on pipeline
Table is disclosed）When the filtration core being arranged in cartridge filter need to be changed or cleaned, cylinder cover need to be opened, it is on the contrary by cylinder cover and cylinder
Mouth sealing coordinates, and aforementioned invention Authorization Notice No. CN102559314B can be referred to this.
Just as water can carry boat again can capsized boat reason, natural gas can be the provider such as people's daily life and industrial and agricultural production
Just, but also with danger, thus as natural air-air source supplying sector to the mistake that is arranged on natural gas transportation pipeline
The installation of filter is attached great importance to, and especially the technical requirements to the cylinder cover for being engaged with cylinder mouth are very harsh, specifically
For, at least show as the following aspects；First, cylinder cover and cylinder oral area position（I.e. with the hub position of cylinder）Must have
There is excellent sealing, to avoid leakage；Second, when cylinder cover and cylinder oral area position are coordinated, can ensure that the four of cylinder cover
Occur under circumferential edges position and cylinder mouthful positive lock, the pressure to avoid the natural gas in cylinder cylinder cover loosen so that from
Open（Also it can claim to escape）The dangerous situation of cylinder occurs；Third, what cylinder cover was turned on and off is easy to operate.
It can be equally seen on cartridge filter nozzle sealing device technical information in disclosed Chinese patent literature, such as
CN101737622A（Lock-ring safety quick open blind plate）、CN203614730U（A kind of fast opening blind of easy access）With
CN101038060A（Lock band embedded quick-opening blind plate）, etc..
The sealing means for being not limited to the cartridge filter nozzle sealing device of above mentioned patent are commonly used and are similar to
The subdivision ring introduced by CN105240526A（I.e. " four points of rings ", as follows）Structure type, thus when face Horizontal type natural gas
Just exposure is following during separator-filter leads to disadvantage：Four points of rings, which occur, to be slid or beats downwards tiltedly（It is crooked）Situation, and once four points
Ring slide or it is crooked, then it is light then cause install trouble（Because need to be by four points of ring rightings）, it is heavy then because of sealing effectiveness it cannot be guaranteed that
And cause natural gas leaking；In addition, when the filtration core in cartridge filter to be changed, due to there is residual pressure in cylinder, therefore
If effectively residual pressure can not be discharged, easily occurs accident when opening cylinder cover.
The content of the invention
