Description

Flexible stop valve pipeline connection part in the rigid conduit connected system
What the present invention relates to is a kind of pipeline connection part, particularly be a kind of be used for cartridge type that rigid conduit connected systems such as metal tube, composite metal-plastic pipe, metallic skeleton reinforced composite plastic pipe, hole pattern steel-plastic composite pipe, hard polymer pipe are connected with pipeline, pipe fitting can block the flexible stop valve pipeline connection part that fluid replaces the stop valve function.
In the pipework system, the design and installation shutoff valve, their effect is for throttling or cuts off fluid that distributing fluids is to the pipeline distributing fluids of the needs flow direction.Sometimes be in order to adorn new pipe network or to overhaul pipe network and need cut off fluid.Existing stop valve majority is that metallic material is made, and for the needs of anticorrosion and engineering, is coated with polymer on the metal checking-valve body, coated polymer or synthetic rubber, the stop valve that the Environmental Conditions that some pressure rating is not high has brought into use polymer to make.Above-mentioned these stop valves such as rigidity requirements such as gate valve, butterfly valve, installation dimension requirement, dimension precision requirement, seal request, material requirements are all higher, so price is more expensive, also are inconvenient to operate in engineering is used, and generally will reserve conduit shaft.If bury the perishable and inconvenient operation in ground.Particularly the combustion gas in the urban pipe network is carried, tap water is carried, delivery, sewage transport and oil, the oil and natural gas exploitation of gasoline is carried, and the supply and drain water system in oil field, be difficult in advance the opening of pipe network being planned accurately with adapter and being designed, after pipe network installs, in using process from now on, tend to excavate pipe network new opening and adapter on pipe network again because of needs, this pipe-line system for rigidity is with high costs, the many expensive anti-corrosion of metal stop valves of design and installation in some calculable planning and designing so have to, and cost throughout the year it is carried out anticorrosion maintenance and flight-line maintenance, safeguard.Because the installation fee of this class stop valve and operation maintenance cost cost price are more expensive, in pipe-line system, have to reduce design quantity as far as possible, this takes over for pipe network opening afterwards not only needs but also has increased the expense and the cost that take place of having in a large number, the particularly opening of some main transmission pipeline networks and adapter, uncertainty in advance because of planning and designing, when needing opening to take over afterwards, because of not burying underground in advance or mounted valve, make opening take over engineering and have to make the person in charge to stop to carry, the loss that causes like this is just bigger.For conveniently damming and dam, main line afterwards reduces stoppage in transit and the loss of user on the pipe network, certainly primary is the stop valve quantity that increases on the main line, do not carry in order not influence main line in main line upper shed, adapter, on the main line of estimating opening, adapter in the future, all set up and reserve threeway or four-way pipe coupling, and for convenient at these joint upper connecting tubes and do not influence main line and carry, default and pre-buried stop valve in the pipe coupling of these threeways, four-way is not carried so that do not influence main line when this opening adapter and conveyance fluid as much as possible.Realize that such adapter is convenient, no matter from installation cost, on the maintenance cost, all be infeasible if adopt existing stop valve.
In view of above reason, the objective of the invention is for a kind of various anti-corrosion of metal stop valves that replace are provided, the pipe-line system cost is reduced, it is also easy to operate to make things convenient for opening to take over, also can use with burying, save a large amount of installation costs and maintenance cost, reduce the rigid conduit system because of the flexible stop valve pipeline connection part in the rigid conduit connected system of the stoppage in transit loss of opening adapter.
The object of the present invention is achieved like this:
