Abstract
The utility model relates to a kind of tank deck self-checking devices.Its technical solution is: being equipped with pressure regulation tube line at the top of storage tank, the shut-off valve before the left end of pressure regulation tube line is equipped with valve, the right end of shut-off valve is connected with filter before valve, direct-operated regulator is connected by connecting pipe in the right end exit of filter, is connected with shut-off valve after valve in the right end of direct-operated regulator.Beneficial effect is: being cleverly combined with each other direct-operated regulator and common shut-off valve, accurate control tank deck pressure is achieved the purpose that, to make nitrogen pressure obtain good control, reduce nitrogen consumption, so that the nitrogen pressure in storage tank is in suitable slight positive pressure state always, effectively completely cut off moisture enter, and because its without electricity, without gas the characteristics of, it is preferably minimized the risk of fire, explosion, effectively increases the safety of tank field.
Description
Technical field
The utility model relates to a kind of pressure-regulating device, in particular to a kind of tank deck self-checking device.
Background technique
It is temporary that the chemical products of chemical plant installations production need storage tank, but partial material is easy water suction in storing process, leads
The Moisture high UCL of material is caused, material is unqualified.To solve this problem, tank field uses nitrogen protection storage tank, and storage tank is made to keep micro-
Positive pressure prevents the entrance of moisture, but protecting the pressure control of gas is common problem, controls according to common valve, will lead to tank
The problems such as interior pressure controls not in time, and nitrogen wastes controls, it will lead to high expensive according to valve group is adjusted.
Summary of the invention
The purpose of this utility model provides a kind of tank deck automatic adjustment dress aiming at drawbacks described above of the existing technology
It sets, improves the self-regulation ability of storage tank, guarantee the control of pressure of storage tank.
Its technical solution is: the utility model include shut-off valve after shut-off valve, filter, direct-operated regulator, valve before valve,
Connecting pipe, by-pass shut-off valve are equipped with pressure regulation tube line at the top of storage tank, cut before the left end of pressure regulation tube line is equipped with valve
Only valve, the right end of shut-off valve is connected with filter before valve, is relied on oneself in the right end exit of filter by connecting pipe connection
Formula regulating valve is connected with shut-off valve after valve in the right end of direct-operated regulator.
The top of above-mentioned pressure regulation tube line is equipped with valve group by-pass, and by-pass shut-off valve is equipped on valve group by-pass.
The beneficial effects of the utility model are: being cleverly combined with each other direct-operated regulator and common shut-off valve, reach
The purpose of accurate control tank deck pressure reduces nitrogen consumption, makes in storage tank so that nitrogen pressure be made to obtain good control
Nitrogen pressure is in suitable slight positive pressure state always, effectively completely cut off moisture enter, and because its without electricity, without gas the characteristics of, make
Fire, explosion risk be preferably minimized, effectively increase the safety of tank field.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of the utility model；
In figure: shut-off valve 4, connecting pipe 5, by-pass shut-off valve after shut-off valve 1, filter 2, direct-operated regulator 3, valve before valve
6。
Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
The utility model include shut-off valve 4 after shut-off valve 1, filter 2, direct-operated regulator 3, valve before valve, connecting pipe 5,
By-pass shut-off valve 6 is equipped with pressure regulation tube line at the top of storage tank, the shut-off valve 1 before the left end of pressure regulation tube line is equipped with valve,
The right end of shut-off valve 1 is connected with filter 2 before valve, connects self-operated type by connecting pipe 5 in the right end exit of filter 2
Regulating valve 3 is connected with shut-off valve 4 after valve in the right end of direct-operated regulator 3.
Wherein, the top of pressure regulation tube line is equipped with valve group by-pass, and by-pass shut-off valve 6 is equipped on valve group by-pass, can
Convenient for the maintenance of valve group on pressure regulation tube line.
Tank top gas enters filter by shut-off valve before pressure regulation tube line upper valve, from filter outlet by leading
Pressure pipe enters direct-operated regulator detection executing agency, when gas pressure is more than the pressure of direct-operated regulator setting, relies on oneself
The valve that formula regulating valve can change to automatically adjust using pressure itself, excessive gas pass through shut-off valve after valve, reduce storage
Pressure tank；By-pass shut-off valve is equipped on valve group by-pass, it can be convenient for the maintenance of valve group on pressure regulation tube line.
Direct-operated regulator is a new regulating valve type.Relative to manual modulation valve, its advantages are can be automatic
It adjusts；Relative to electric control valve, its advantages are not need external impetus.Using be conditioned medium pressure itself variation come into
The valve of row automatic adjustment is that controlled medium is introduced executing agency's generation power effect according to mechanics principle to push, control valve core
Element upper and lower displacement reaches automatic adjustment, constant pressure or the energy-saving product of decompression before valve or after valve.Its maximum feature is can be
Place work without electricity, without gas, pressure set points can be adjusted arbitrarily in operation.It is sensitive, close using quick open flow characteristic
Sealing property is good, preferably controls the stress problems of storage tank.Cleverly direct-operated regulator and common shut-off valve are combined with each other,
Accurate control tank deck pressure is achieved the purpose that, so that nitrogen pressure be made to obtain good control, has reduced nitrogen consumption, make storage tank
Interior nitrogen pressure is in suitable slight positive pressure state always, effectively completely cuts off moisture and enters, and because of it without electricity, the spy without gas
Point is preferably minimized the risk of fire, explosion, effectively increases the safety of tank field.
The above, is only the preferred embodiment of the utility model, and anyone skilled in the art may benefit
Equivalent technical solution is modified the utility model or is revised as with the technical solution of above-mentioned elaboration.Therefore, foundation
Any simple modification or substitute equivalents that the technical solution of the utility model is carried out belong to the greatest extent the requires of the utility model protection
Range.
