Abstract
The invention discloses a system for preventing liquid in a pipeline from expanding. The system comprises a plurality of valves, a pressure pump and a storage tank, the valves, the pressure pump and the storage tank are sequentially connected in series, the valves comprise a feeding valve, an inlet valve, an outlet valve and a discharging valve, the storage tank is connected with the discharging valve through a pipeline, the discharging valve is connected with the inlet valve through a pipeline, the inlet valve is connected with an inlet of the pressure valve through a pipeline, an outlet of the pressure pump is connected with the outlet valve, the outlet valve is connected with the feeding valve through a pipeline, the upper portion of the discharging valve is connected with an overpressure recycling device in parallel, the overpressure recycling device comprises a one-way check valve and a ball valve, and the lower portion of the discharging valve is connected with a blow-off valve in parallel. The upper portion of the discharging valve is connected with the overpressure recycling device in parallel, when materials in the pipeline generate overpressure due to a temperature difference, the overpressure is made to flow into the storage tank through the one-way check valve along the pipeline, and therefore the situation that the overpressure flows back into the pipeline due to the fluidity of the overpressure, and components in the pipeline are damaged is avoided. An unloading device is arranged in the storage tank, it is guaranteed that the pressure intensity inside and outside the storage tank is consistent, and the safety coefficient of the pipeline and the storage tank is improved.
Description
Technical field
The present invention relates to chemical field, specifically, particularly relate to a kind of system preventing expansion of liquids in pipeline.
Background technique
After sales company receives order; need deliver from chemical industry warehouse; material is delivered to transport vehicle from the outlet port of storage tank through pipeline and corresponding conveying equipment; after mass transport is complete; by the valve closing of pipeline; due to the effect of inertia of partial material; material is made to flow in storage tank through back of pipeline; and material flow to storage tank process from pipeline; material, along Flows, because of the relation of the temperature difference, causes material particularly the expanding with heat and contract with cold of harmful influence; superpressure is caused to pipeline, very easily destroys pipeline and parts thereof.In course of conveying in the market, special system is not set, device solves this and cause because of the temperature difference material to the problem of pipeline superpressure, when the vulnerable area of the pipeline such as valve, pad is once destroyed, then great harm is caused to the security of the lives and property of workshop, people, also greatly endanger ecotope simultaneously.
Summary of the invention
The invention discloses a kind of system preventing expansion of liquids in pipeline, superpressure in pipeline cannot process for solve in conventional art, pipe fitting easily destroyed, conveying and the low problem of storage process safety coefficient.
The present invention is achieved by the following technical solutions:
A kind of system preventing expansion of liquids in pipeline, comprise multiple valves of connecting successively, pressure pump, storage tank, described multiple valve comprises discharging valve, inlet valve, outlet valve, discharge valve, described storage tank is connected with discharge valve by pipeline, described discharge valve is connected with inlet valve by pipeline, described inlet valve is connected with the import of pressure pump by pipeline, described pressure delivery side of pump is connected with outlet valve, described outlet valve is connected with discharging valve by pipeline, the top of described discharge valve is parallel with superpressure reflux, described superpressure reflux comprises one way stop peturn valve, ball valve, the below of described discharge valve is parallel with blowdown valve.
Described one way stop peturn valve is in series by pipeline and described ball valve.
The side of described storage tank is provided with upper and lower two outlets, and bottom is provided with sewage draining exit.
One end of described ball valve is connected with described one way stop peturn valve, and the other end is connected with the upper outlet of described storage tank side.
Described ball valve also can be other closable valves.
The lower outlet of described storage tank is connected with described discharge valve.
The sewage draining exit of described storage tank is connected with described blowdown valve.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention is by superpressure reflux in parallel above discharge valve, after conveying material terminates, material in pipeline is because of the relation generation superpressure of the temperature difference, superpressure flows in storage tank along pipeline through one way stop peturn valve, thus avoid superpressure because of mobility and, again in flow ipe, destroy conduit component, and storage tank is provided with evacuating device, guarantee the consistent of the inside and outside pressure of storage tank, improve the safety coefficient of pipeline and storage tank; And be in series with ball valve with one way stop peturn valve, if one way stop peturn valve damages, then by closing ball valve, avoiding material to circulate through this, facilitating the replacing of one way stop peturn valve; Superpressure reflux of the present invention only can be made up of by throttle down one way stop peturn valve and other simultaneously, and structure is simple, and cost is few, can widely use.
Accompanying drawing explanation
Accompanying drawing is the schematic diagram of the embodiment of the present invention.
In figure: 1, pressure pump; 2, storage tank; 3, discharging valve; 4, inlet valve; 5, outlet valve; 6, discharge valve; 7, one way stop peturn valve; 8, ball valve; 9, blowdown valve.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described:
A kind of system preventing expansion of liquids in pipeline, comprise multiple valves of connecting successively, pressure pump 1, storage tank 2, described multiple valve comprises discharging valve 3, inlet valve 4, outlet valve 5, discharge valve 6, described storage tank 2 is connected with discharge valve 6 by pipeline, described discharge valve 6 is connected with inlet valve 4 by pipeline, described inlet valve 4 is connected by the import of pipeline with pressure pump 1, the outlet of described pressure pump 1 is connected with outlet valve 5, described outlet valve 5 is connected with discharging valve 3 by pipeline, the top of described discharge valve 6 is parallel with superpressure reflux, described superpressure reflux comprises one way stop peturn valve 7, ball valve 8, the below of described discharge valve 6 is parallel with blowdown valve 9.
Described one way stop peturn valve 7 is in series by pipeline and described ball valve 8.
The side of described storage tank 2 is provided with upper and lower two outlets, and bottom is provided with sewage draining exit.
One end of described ball valve 8 is connected with described one way stop peturn valve 7, and the other end is connected with the upper outlet of described storage tank 2 side.
Described ball valve 8 also can be other closable valves.
The lower outlet of described storage tank 2 is connected with described discharge valve 6.
The sewage draining exit of described storage tank 2 is connected with described blowdown valve 9.
When material carry on request complete after, close discharging valve 3 of the present invention, discharge valve 6, blowdown valve 9, unnecessary material is along Flows, refluxed by inlet valve 4, because the chemical characteristics of the temperature difference and material self makes material expand with heat and contract with cold, superpressure is caused to pipeline, superpressure is along pipeline flow to one way stop peturn valve 7, superpressure is by flowing into storage tank 2 after one way stop peturn valve 7, due to the characteristic of one way stop peturn valve 7 valve, avoid superpressure from valve Returning pipe, and then to the hurtful problem of pipeline, and after superpressure enters storage tank 2, because storage tank 2 is provided with evacuating device, thus ensure that the conformity of the inside and outside pressure of storage tank 2, improve the safety coefficient of whole system, structure of the present invention is simple simultaneously, little investment, chemical field can be widely used in.
