Abstract
The utility model relates to a bag-type sealing cover for loading and unloading of tanker oil product. The bag-type sealing cover comprises an outer bag, an air bag, an outer bag movable head, an outer bag fixing head, a sleeve pipe, an air inlet pipe of the air bag, an air phase pipe, a high liquid level warning probe and a liquid phase pipe. An air bag fixing element is arranged on the periphery of the sleeve pipe, the air bag is arranged between the sleeve pipe and the air bag fixing element, the air phase pipe and the liquid phase pipe of a loading arm are sleeved concentrically, and the air bag is arranged in the outer bag. As the structure of the air bag and the outer bag are used, a feature that the air bag is deformed after air inflation is used and the unique movable outer bag is supplemented, the bag-type sealing cover is suitable for various sizes of tankers, parking positions and sealing work requirements of the loading arm under alignment conditions. The sealing cover stretches in a tanker opening during work and inflates the air bag, and the sealing cover is inflated and sealed. The air bag is deflated after work and the sealing cover contracts and separates. The high liquid level warning probe sends out warning signals when loading medium reaches an alert height, and transmits the signals to a quantitative loading control system to achieve closing and locking of pumps and valves and ensure loading work safety.
Description
Technical field
The utility model relates to a kind of tank car oil product loading and unloading with capsule formula closed cover.
Background technology
Transportation at China's clean cargo mainly contains pipeline, railway, highway and water route transportation, except that pipeline transportation, has oil product loading and unloading link in all the other transportations inevitably, can produce a large amount of oil gas loss, causes resources loss and environmental pollution.Be to solve the oil and gas loss in the oil product handling process, atmosphere pollution and to the problems such as health affected of operating personal, mainly through adopting airtight handling technology under the liquid, oil gas recvery facility etc. being set.Closed cover is exactly a key equipment of realizing closed loading.Traditional closed cover mainly contains flat, two kinds of tapered structures, the flat fixed-size tank car of manhole bore that is primarily aimed at; Pyramidal structure can adapt to the tank car of different caliber size; But, make that closed cover can not be airtight with the lid mouth well in use because the existence jar dipped ring of clean-out cover is whole, the skew on parking stall, and nanubrium can not guarantee vertical insertion when inserting tank car; In addition when entrucking; Along with the increase of entrucking capacity, the tank car mouth moves down (particularly train tank car), and closed cover can not move down synchronously and causes seal failure.
The utility model content
The purpose of the utility model is to overcome above-mentioned defective, and the tank car oil product loading and unloading that a kind of good seal performance, long service life and the different caliber size of adaptation are provided are with capsule formula closed cover.
The technical scheme of the utility model: a kind of tank car oil product loading and unloading is characterized in that with capsule formula closed cover described capsule formula closed cover comprises the liquid-phase tube of external capsule, air bag, external capsule movable head, external capsule fixed head, sleeve pipe, air bag air inlet pipe, gas phase pipe, high liquid level warning probe and oil filling riser;
Described sleeve pipe is by the circular upper plate of band centre hole and the T-socket that straight tube is welded; This sleeve pipe periphery is provided with the air bag locations; Between the upper plate of sleeve pipe and the air bag locations air bag is set, promptly Air sac cover is contained between the end plate and air bag locations of T-socket;
High liquid level warning probe and air bag air inlet pipe are set on the described sleeve pipe; This air bag air inlet pipe is communicated with air bag; The gas phase pipe is arranged on the upper plate central hole of sleeve pipe and passes through screw fastening; The liquid-phase tube concentric suit of gas phase pipe and oil filling riser, promptly this liquid-phase tube is in gas phase pipe, sleeve pipe extend the tank car mouth, and the liquid-phase tube bottom of oil filling riser is provided with the telescopic pipe flange;
Described air bag is arranged in the external capsule; This external capsule is respectively equipped with external capsule fixing head and external capsule movable head in two ends up and down; Be that the external capsule fixing head is arranged on external capsule upper end and is fixed on the circular upper plate of sleeve pipe by screw; Movable first end of external capsule and external capsule lower end are fastenedly connected by screw, and the other end touches with the straight tube of sleeve pipe mutually.
The utility model adopts airbag structure, utilizes the characteristics of airbag aeration distortion, is aided with unique movable external capsule, can adapt to various tank car sizes, the airtight job requirements under stop position and the entrucking oil filling riser alignment.During car loading operation, capsule formula closed cover stretches into tank car mouth inwall, gives the inflation of capsule formula closed cover and expands, and external capsule is attached on the tank car hand-hole inwall firmly, and the tank car mouth is sealed; The volatile gases such as oil gas that produce in the entrucking process cause gas recovery system for oil through the gas phase pipe and recycle.Operation finishes, air bags and shrinking, and outer air bag diminishes and leaves tank car aperture inwall, and air bag separates with tank car mouth inwall, can be easily with carrying on the oil filling riser.Because external capsule has on a fixed head and the movable head; Movable head on the external capsule can slide up and down along the sleeve pipe outer arm; Guarantee seal cover cap all the time not from a jar mouth, thereby accomplish real closed loading, the sealing main material adopts the modification viton; The media-resistant solvent borne is strong, guarantees sealing property and service life.Be furnished with high liquid level warning on the capsule formula closed cover and pop one's head in, when the entrucking medium arrives the Security alert height, send the sound and light alarm signal, simultaneously can be with signal conveys to the quantifying and loading control system, realization pump, valve are closed down chain, guarantee car loading operation safety.
