Description
Technical field
[01] the utility model relates generally to pipeline transporter, especially relates to dense pipe material and distributes reversing arrangement, specifically, relates to a kind of board-like concentrated material distributing valve device.
Background technique
[02] dense material is meant the material that viscosity is thicker.As one of ordinary skill in the known, since line transportation have full closed carry, pollution-free, nothings spilt with material loss, transporting resistance is little, delivery technology is simple, equipment investment is few, piping layout is flexible, landform adaptability is strong, plant area is succinct, attractive in appearance, do not account for or account for less soil, capital investment characteristics such as less, become the optimal transport mode of the high viscous and dense materials of solid, liquid two-phase such as coal slime, mud, calcium carbide mud.
[03] in the process of the industrialized utilization of the disposal of sticky solid waste and other high viscous and dense materials and production, the continuous supply of material is a successional necessary condition of guaranteeing whole manufacturing process, in order to prevent to cause material supply to interrupt, the standby transporting system of a cover usually is set in addition because of the fault of pipe-line transportation system.Traditional mode is that the configuration of standby system and common system is identical, but, following two reasons are difficult to carry out promotion and implementation owing to making it: the one, and the investment of conveyance conduit often will account for whole system investment quite great proportion, but also to be equipped with corresponding shunting device and feeding equipment for standby system, certainly will cause the huge waste of investment, this is that owner institute is unacceptable; The 2nd, because standby system is not worked for a long time, cause that hardening of material causes the conveying tripping force to heighten in the pipeline, requirement to the mechanical strength of entire equipment also increases greatly, power of motor also need provide the bigger margin of power, the power factor of its proper functioning is reduced greatly, cause the waste of electric power energy, thereby increased cost of investment and operation cost.
[04] therefore, be necessary to make standby pumping equipment, feeding equipment and the shared conveyance conduit of pumping equipment, feeding equipment commonly used, when the common equipment fault, conveyance conduit and common equipment disconnected, connect with standby equipment, thereby start standby equipment.Therefore, in the pipe conveying procedure of the high viscous and dense material of solid, liquid two-phase, article one, the delivery main will link to each other with two arms, and can switch the break-make of delivery main and each arm, for realizing this function, original method is on each arm stop valve to be installed, and the opening and closing by stop valve realize the conversion that flows to.This stop valve is complicated operation not only, sealing effect is poor, sealing load is little, valve plate is yielding, and can be in the short tube that links with valve buildup, because higher cohesive force and the frictional force of generation between buildup and the material that flows, transporting resistance is increased greatly, when buildup hardens, even can blocking pipe.
[05] for addressing this problem, the applicant has invented a kind of two-way dense material selector valve, and be called the utility model patent (patent No. is ZL02246210.4) that " the dense material distributor of bidirectional high-pressure " applied for name on August 13rd, 2002, this two-way dense material selector valve not only can switch the break-make of a delivery main and each arm, and can carry out throttling or end the line transportation of dense material, but this two-way dense material selector valve is a cylindrical-shaped structure, in engineering is used, when material pressure is excessive in the excessive or pipeline when pipe diameter, valve body strengthens because of distortion makes between itself and the spool gap, and make material enter the gap, and form a wedge, valve body and spool are blocked and be difficult to relatively move, thereby cause commutation failure; And because this two-way dense material selector valve is a cylindrical-shaped structure, sealing surface is a curved surface, and it is unreliable to seal, and is easy to damage.Therefore, the material pipe commutation becomes a restriction bottleneck in the dense pipe material conveying.Be necessary to develop a kind of new dense material selector valve.
The model utility content
[06] technical problem to be solved in the utility model is: at the defective of two-way dense material selector valve in the prior art, a kind of board-like dense material selector valve device is provided, this board-like dense material selector valve apparatus structure is simple, be easy to commutation, reliable, the easy maintenance of sealing, overcomes two-way dense material selector valve complex structure in the prior art, seals insecure defective.
The utility model provides a kind of board-like concentrated material distributing valve device, it is used at the pipeline communication system selected in a delivery main and two arms arm being communicated with, described board-like concentrated material distributing valve device comprises: the single tube plate, it has total pipeline, described total pipeline has first end and second end, and first end of described total pipeline is suitable for being connected with described delivery main; The double tubesheet fixing with respect to described single tube plate, it has two pipelines, and each described pipeline has first end and second end, and first end of each described pipeline is suitable for being connected with described two arms; Valve body, it is arranged between described single tube plate and the described double tubesheet, be suitable between first working position and second working position, switching, described valve body has two not connected conduit, each described conduit has first end and second end respectively, at place, described first working position, first end of one of described conduit is connected with second end of described total pipeline, and its second end is connected with second end of one of described two pipelines, at place, described second working position, first end of another in the described conduit is connected with second end of described total pipeline, and ducted another second end of its second end and described two arms is connected; Be arranged on first seal arrangement between described single tube plate (2) and the described valve body (3), it is used for realizing that the sealing of described total pipeline and corresponding conduit is communicated with when described valve body (3) is in described first or second working position; And being arranged on second seal arrangement between described double tubesheet (7) and the described valve body (3), it is used for realizing that the sealing of corresponding conduit and corresponding pipeline is communicated with when described valve body (3) is in described first or second working position.Described " sealing be communicated with " means two pipelines and is interconnected, and the joint sealing, avoids wherein fluid (for example viscous fluid or powder) outside the joint leaks into pipeline.
[07] because described single tube plate and described double tubesheet are roughly tabular structure, thereby the junction plane between valve body and described single tube plate and the double tubesheet is the plane.Like this, the fixing single tube plate of movable valve body and its both sides and the sealing configuration between the double tubesheet only need the sealing surface on plane is sealed.On the one hand, avoid the shortcoming of the manufacturing difficulty that the cylindrical-shaped structure of two-way dense material selector valve causes in the prior art, on the other hand, avoided the sealing that cylindrical-shaped structure caused difficulty and insecure shortcoming of two-way dense material selector valve in the prior art.
