Description

A kind of open and close method of pipeline non-return valve, flashboard valve assembly
Technical field
The invention belongs to pipeline valve maintenance technology fields, are related to a kind of in the premise for not influencing power conduit media flow Under the conditions of, by pipeline non-return valve, the open and close online production of flashboard valve assembly, repair or valve spool of valve is replaced, more particularly to A kind of open and close method of pipeline non-return valve, flashboard valve assembly.
Background technology
Currently, metallurgy, ore dressing, oil, chemical industry, coal fired power generation, nuclear power generation, nuclear power, coal gas, natural gas, steaming both at home and abroad Slide valve, non-return valve, ball valve, cylindrical valve that vapour, sewage purification, water supply pipe etc. use etc., generally existing:There is medium Power conduit flowing, just have the opening and closing devices such as slide valve, non-return valve, barrel valve.These device main functions are ensuring that institute The production that needs, life, maintenance, control flow, ensure all kinds of technique normal operations.But various pipes slide valve, non-return valve, circle When the opening and closing devices such as column valve were used to latter stage, it is necessary to be overhauled and be replaced after sealing and stopping service line media flow, even The opening and closing devices such as slide valve, non-return valve, the barrel valve of key position, which are repaired and replaced, must carry out completely stopping production as maintenance more The fundamental prerequisite changed.The replacing valve period that tradition uses is generally 1 to 3 year, and the maintenance for operation late gate of going into operation is replaced also A large amount of expenses need to be spent, on-line maintenance can not be carried out, replace the problems such as valve body, spool by existing.
Invention content
The present invention overcomes above-mentioned existing defects, it is therefore an objective to not influence power conduit media flow for further solution Under precondition, provide it is a kind of have simple in structure, operation flexibly, safeguard and replace convenient, be suitable for a variety of valve combinations of pipeline The pipeline non-return valve of body on-line maintenance, replacement valve body, spool etc., the open and close method of flashboard valve assembly.
The open and close method content Description of inventive pipeline non-return valve, flashboard valve assembly:
The open and close method of inventive pipeline non-return valve, flashboard valve assembly, it is characterised in that:Pipeline non-return valve, slide valve valve Assembly, including:Non-return valve and non-return valve, slide valve and slide valve on pipeline with it is coaxial, intersect, with one heart, it is vertical, opposite, Symmetrically, independence and when rotary spool combination settings, pipeline non-return valve, flashboard valve assembly open and close method;
Pipeline non-return valve, flashboard valve assembly by:Medium, medium inlet pipeline, valve I, media outlet pipeline, spool valve Bar I, valve core valve stem II, fastening bolt, valve spool of valve I, valve spool of valve II and valve II form, medium inlet pipeline and Jie Matter outlet conduit is arranged on valve I, valve II, and in medium inlet, the junction of pipeline and media outlet pipeline is in 0~180 degree angle, valve I, valve II are arranged between medium inlet pipeline, media outlet pipeline;Or valve When valve body I, valve II are vertically arranged, valve I, valve II are arranged in medium inlet pipeline, media outlet pipe The other end in road;Or medium inlet pipeline is in plumbness setting with valve I, valve I and valve II.
The open and close method of pipeline non-return valve, flashboard valve assembly refers to:When online production I working condition of valve spool of valve, Stop the open and close side of pipeline non-return valve, flashboard valve assembly when valve spool of valve I, II free state of valve spool of valve when online production Method:
(1), when online production valve spool of valve I works normally, medium is entered by medium inlet pipeline, and valve spool of valve II is in Free state, valve spool of valve I are in open state, and medium is flowed out by media outlet pipeline, can replace valve spool of valve II at any time;
(2), when stop online production valve spool of valve I be rotated by 90 °, valve spool of valve II is in free state, can replace valve at any time Spool II;
(3), slide valve and slide valve be when combining, when online production valve spool of valve I works normally, medium is managed by medium inlet Road enters, and valve spool of valve II is in free state, and valve spool of valve I is in open state, and medium is flowed out by media outlet pipeline, Valve spool of valve II can be replaced at any time;
(4), slide valve and slide valve be when combining, be closed when stopping online production valve spool of valve I, medium enters medium Pipeline stops outflow, and valve spool of valve II is in free state, can replace valve spool of valve II at any time.
The open and close method of inventive pipeline non-return valve, flashboard valve assembly, solving valve spool of valve can not be tieed up online The problem for repairing, replacing spool passes through different open and closes, changeover valve spool under conditions of service line does not stop media flow Sequence, realize valve body spool on-bne repair freely.On especially toxic, unwanted dynamics pipeline, the flashboard of single use Valve, ball valve, non-return valve maintenance, update bring great convenience.
