Abstract
The utility model relates to an automatic intake valve for oil depot pipelines, which comprises a valve body, an upper cover of the valve body, a lower cover of the valve body, a cover sealing body, etc. A sealing body is arranged at the upper end of the upper cover of the valve body, and the lower end is pressed tightly by a spring; the sealing body is in slide matching with the cover sealing body; a float body is arranged in the valve body; the float ball is supported by a round ring with a side groove; the center of the float ball is fixed to a guide bar on which a taper valve core is fixed; a taper valve body matched with the taper valve core is arranged at the lower end of the upper cover of the valve body. The valve has an automatic intake function when the oil depot pipeline is emptied, and has functions of oil blocking and oil vapor isolation, with safety and convenience.
Description
The utility model belongs to the oil movement and storage technical field, is specifically related to a kind of automatic admission valve that is used for the piping for tank farm emptying.
Usually, oil depot finishes or needs maintenance because of equipment and pipeline damage in the oily operation of transmitting-receiving, all wants the oil product in the emptying pipe.Tradition emptying operation before the emptying, is closed oil tank turnover oil control valve by manually finishing earlier, opens the valve on the emptying pipe then along the line; During emptying, open the valve on the preceding air intake branch of oil storage tank, rely on the effect of atmospheric pressure and the gradient of pipeline, make air enter pipeline, the oil product emptying enters in the blow-down tank; After the emptying, close the valve of air intake branch and all valves on the emptying pipe.This operating type mainly exists two aspect problems.The one, because the distance of oil storage tank and blow-down tank is far away, the contact difficulty makes inconvenient operation: the 2nd, forget the valve of closing air intake branch after the emptying easily, and when causing next oil transportation, oil product is emerged from the air intake branch mouth, causes oil leak accident; Or oil gas discharged by pipeline, and the personnel that cause poison, and jeopardize life safety.
The purpose of this utility model is at existing process engineering above shortcomings, air inlet automatically when a kind of piping for tank farm emptying is provided, and oil resistance is arranged and isolate the piping for tank farm emptying automatic admission valve of oily vapours function.
The technical solution of the utility model is as follows:
Piping for tank farm emptying automatic admission valve comprises valve body and valve upper cover, valve body lower cover, closure body etc., and seal is established in the upper end of valve upper cover, and down by spring compression, seal and closure body are slidingly matched; Establish ball float in the valve body, ball float center fixation one guide rod is fixed a tapering spool on the guide rod, and the tapering valve body of Pei Heing is arranged on the lower end of valve body lower cover with it.Stationary positioned plate and back-up ring in the valve upper cover, guide rod is passed by the positioning plate center, establishes in the valve body and the corresponding localization frame of ball float size, and seal is a spill cavity, and the chamber jar is established side opening.Annulus seat supports ball float is established at valve body lower cover middle part, and annulus bearing sidewall is opened side channel; The lower end of valve body lower cover is connected with joint screw thread.On seal, tapering spool and each junction of valve body establish seal ring or sealing gasket.
This valve is installed on the oil tank air intake branch of oil depot, its working procedure is as follows: (1) air inlet: during pipe evacuation, valve inner produces negative pressure, when negative pressure reaches a threshold value, the elastic force that seal overcomes spring moves down, air again by the side channel of ball float annulus bearing enters into pipeline by side opening via valve pocket from the seal center, and ducted oil product is compressed into drain tank along the line.(2) oil resistance: pipeline is not during emptying, ducted oil product is subjected to the effect of jar interior static pressure to enter valve pocket, make the ball float come-up in the chamber, when ball float reaches certain position, buoyancy function is fitted the tapering valve body core and the tapering valve body on the valve upper cover that are positioned on the ball float guide rod, reliably stops oil product to leak.(3) isolate: behind the pipe evacuation not during the trapped fuel, though ball float is floating not, the tapering valve body is in not closed condition, the top seal body under spring action with the closure body driving fit, guarantee the isolation of pipe interior and external environment condition, prevent that effectively oily vapours from entering among the air.
Diameter and the thickness of inlet seal circle cracking pressure and the air inflow of regulating emptying automatic admission valve of the utility model by changing Spring Steel Wire.
Advantage of the present utility model: the one, automatically air inlet owing to when need not oil product in each emptying pipe, must open the valve on the air intake branch earlier, makes operation become convenient; The 2nd, automatically oil resistance, even after the emptying operation finishes, operator forget and close the air intake branch valve that the oily operation of transmitting-receiving next time oil leak accident can not take place yet; The 3rd, can isolate oily vapours automatically, pipeline is not among the steam that oil evaporation residual after the emptying produces can enter into atmosphere.Thereby can eliminate the unsafe factor that personnel that jar chamber or operation room cause owing to gas concentration is excessive poison.
Below in conjunction with drawings and Examples the utility model is described further;
Fig. 1 is a piping for tank farm emptying automatic admission valve structural drawing.
Embodiment:
As shown in Figure 1, this automatic admission valve comprises valve body 12, and valve body 12 is import and outlet up and down, and import is formed by connecting by closure body 1 and loam cake 6, and junction point is by sealing gasket 5 sealings.Outlet is made up of joint 16 and lower cover 14, and the joint is by sealing gasket 5 sealings.Loam cake 6, lower cover 14 also seal with sealing gasket 5 with valve body 12 junction points.Establish seal 2 in the loam cake, seal 2 is a spill cavity, and the chamber wall is established side opening 3 in order to ventilation.Seal 2 bottoms are upwards withstood by spring 4, and seal 2 is slidingly matched with closure body 1, and sealing gasket 5 sealings are established in the junction.Establish a ball float 11 in the valve body 12, ball float 11 is supported by the annulus bearing 20 at lower cover 14 middle parts, and round bearing 20 has side channel, in order to blowing air.Ball float 11 center fixation one guide rod 9 is fixed a tapering spool 15 on the guide rod 9, cooperates with the tapering valve body 17 of valve upper cover 6 lower ends to form the tapering valve, and by 10 sealings of O RunddichtringO.Also be fixed with a positioning plate 8 and back-up ring 7 in the import, guide rod 9 passes from positioning plate 8 centers, and the tapering valve is play the guiding role, and makes it accurate driving fit.In valve body 12, also be provided with a localization frame 13, corresponding with ball float 11 sizes, in order to the ball float 11 of whereabouts, location.Observe for ease of the operator, valve body 12 1 sides adopt transparent design, fix a perspective board 18 with screw 19, and itself and valve body 12 junctions seal with sealing gasket 5.
