Abstract
The utility model relates to an oil gas recycling seal joint comprising an air suction pipe [1], a pressing ring [2], a seal cover [4], seal felts [5] and a bottom cover [6]; the upper part of the seal cover [4] is connected with the air suction pipe [1] through the pressing ring [2]; the bottom cover [6] is movably connected with the lower part of the seal cover [4]; one of the seal felts is arranged between the bottom cover [6] and the seal cover [4], and the other seal felt is arranged between the bottom cover [6] and an exhaust pipe, so that a sealing function is realized; and the seal cover [4] is provided with a handle [3]. The oil gas recycling seal joint is provided with the bottom cover, so that oil gas exhausted through an exhaust cap enters an oil gas recycling device through the air suction pipe to realize oil gas recycle in an oil product shipping process; and the oil gas recycling seal joint is simple in operation, convenient to use and capable of effectively reducing environment pollution and reducing potential safety hazards.
Description
Technical field
The utility model relates to a kind of oil gas and reclaims oil gas recovery seal joint in the seal joint, particularly oil product shipment process.
Background technology
At present, for the oil gas that produces in the oil product shipment process, majority is directly to be discharged in the atmosphere through exhaust cap, and this mode not only causes bigger environmental pollution, but also is unfavorable for recycling, also possibly bring potential safety hazard simultaneously.
CN2694089Y discloses the seal joint in a kind of oil article vehicle process, adopts hemisphere face sealing structure head, under the situation of not changing oil filling riser, realizes closed loading.On the sphere collar of sealing head bottom, deflation hole is set, the oil gas in the tank car is transported in the seal joint housing through deflation hole, set out gas port, send into gas concentration unit through air extractor duct on housing top.The weak point of this structure is can't realize between the top sphere collar and oil filling riser sealing, causes the oil gas in the annular seal space head to leak from here.
CN2796873Y discloses the obturator in a kind of oil article vehicle process; Employing has the Long Circle closing plate of major and minor axis; At the upper surface of closing plate fixed installation ball plate; And the ball core is housed in the ball plate, and captive joint with the lower surface of returnable in the upper surface of ball core, and ventilation flue's a end is contained in the through hole of returnable sidewall.During work, the ball plate can guarantee that tank car jar mouth circumferential edge sealing force equates, improves sealing effectiveness around the inclined to one side give part of a turn of ball core.The weak point of this structure is to have the gap between ball core and the ball plate, can't realize airtightly, causes oil gas to leak from here.
Summary of the invention
To the deficiency of prior art, the utility model provides oil gas recovery seal joint in a kind of oil product shipment process, is intended to solve sealing arrangement of the prior art and still has leak point, the problem that causes oil gas not reclaim fully.
It is following that the utility model oil gas reclaims seal joint structure: be made up of aspirate tube 1, trim ring 2, seal closure 4, seal felt 5 and bottom 6; Said seal closure 4 tops are connected with aspirate tube 1 through trim ring 2; Bottom 6 adopts to live with seal closure 4 bottoms and is connected, and between bottom 6 and the seal closure 4 seal felt is set, and between bottom 6 and the freeing pipe seal felt is set, and realizes sealing function; Seal closure 4 is provided with handle 3.
The utility model is placed on seal closure on the exhaust cap of oil carrier in use, and the oil gas of discharging from exhaust cap gets into aspirate tube through the gas channel on the trim ring.
The utility model in use, bottom is connected with the seal closure that places, the seal felt of packing into is simultaneously realized sealing function.
Can adopt bolt between the described bottom of the utility model and the seal closure or connect flange soon and be connected.
The seal closure of oil gas recovery seal joint can be for square or circular in the described oil product shipment of the utility model process.
In the utility model, the edge coincide with the exhaust cap profile in the trim ring, is convenient to the location, has teeth groove on the trim ring, forms gas channel, and the oil gas of discharging gets in the aspirate tube through gas channel.
In the utility model, aspirate tube is a metallic hose, is connected to device for recovering oil and gas, can satisfy and when hull rocks, reclaim oil gas.
In the utility model, can adopt clamp to be connected between aspirate tube and the seal closure, also can adopt to connect flange soon and connect.
In the utility model, seal closure is provided with handle, is convenient to loading and unloading.
Compared with prior art, the utility model is through being provided with bottom, and the oil gas that exhaust cap is discharged gets into device for recovering oil and gas through aspirate tube; Realize that the oil gas in the oil product shipment process reclaims, simple to operate, easy to use; Can effectively reduce environmental pollution, reduce potential safety hazard.
Description of drawings
Fig. 1 reclaims the seal joint structure scheme drawing for the utility model oil gas;
Fig. 2 reclaims seal joint trim ring structural representation for the utility model oil gas;
Wherein: 1-aspirate tube, 2-trim ring, 3-handle, 4-seal closure, 5-seal felt, 6-bottom, 7-gas channel.
The specific embodiment
Further specify the concrete scheme and the occupation mode of oil gas recovery seal joint in the utility model oil product shipment process below in conjunction with accompanying drawing.
By illustrated in figures 1 and 2, oil gas recovery seal joint is made up of aspirate tube 1, trim ring 2, seal closure 4, seal felt 5 and bottom 6 in the utility model oil product shipment process.Said seal closure 4 tops are connected with aspirate tube 1 through trim ring 2; Bottom 6 adopts to live with seal closure 4 and is connected, and is equipped with seal felt 5 between bottom 6 and seal closure 4 and the freeing pipe, realizes sealing function; Seal closure 4 is provided with handle 3.
Compared with prior art, the utility model is through being provided with bottom, and the oil gas that exhaust cap is discharged gets into device for recovering oil and gas through aspirate tube; Realize that the oil gas in the oil product shipment process reclaims, simple to operate, easy to use; Can effectively reduce environmental pollution, reduce potential safety hazard.
