Description
Technical field
What the present invention relates to is the valve arrangement field, refers more particularly to granular material Pneumatic conveying pipeline flow control valves such as a kind of blast-furnace coal powder injection system.
Background technology
Progressively raising along with the factory automation degree; In the blast-furnace coal powder injection system; Can automatically adjust to rate-of flow in the Pneumatic conveying pipeline as required, pipeline system weares and teares or adjusting coal dust operational throughput to reduce, so control cock has obtained increasing application.
But because the characteristic of gas-powder flow, need regulate the valves can accurate flow adjustment, has self-cleaning, wear-resisting, explosion-proof characteristic simultaneously.
Therefore, need a kind of simple in structure, self-regulating valve of flow of being applicable to gas powder two-phase medium of design.
Summary of the invention
Technical matters to be solved by this invention is the technical deficiency to above-mentioned existence, provides a kind of simple in structure, can carry out accurate flow control and adjusting to gas powder medium, and have the spherical flow control valve of strong wear-resisting effect and self-cleaning ability.
For solving the problems of the technologies described above, technical scheme of the present invention is following: spherical flow control valve, and it includes valve body; Valve body includes valve body and is connected the flange at valve body two ends, it is characterized in that: have import and the outlet that is connected in the middle of the described valve body, import and outlet be into outside bore big; Little horn-like of the inside bore; In the middle vacancy of import with the outlet connecting portion, be provided with the valve seat that two is connected, V-type ball valve core is installed in the valve seat; V-type ball valve core and valve seat are for be tightly connected firmly, and V-type ball valve core is respectively arranged with upper valve rod and the lower valve rod that is used to rotate V-type ball valve core in two ends up and down.
In such scheme, described import and outlet inwall, and the inwall in the middle vacancy of import and outlet connecting portion; Be provided with one deck wear-resistant ceramic liner; Its hardness is only second to adamas, and wear resisting property is considerably beyond wear-resistant steel and corrosion-resistant steel, under equal operating mode; Prolong service life of equipment greatly, be applicable to the dielectric property of coal spraying pipeline.
In such scheme, the material of described V-type ball valve core also is a wear-resistant ceramic, and V-type ball valve core is close to valve seat and is rotated, and when rotating to certain angle, the V-type slit appears in seals at, and increases with the anglec of rotation, and the slit increases thereupon, is used to regulate the flow of gas powder.
Spool adopts V-type ball valve core; V-type ball valve core is in turning course; V-notch and valve seat produce powerful impurity such as shearing force ability cut fibres, avoid the valve stuck phenomenon to take place, simultaneously owing to be the revolution of no gap between spool and the valve seat; Incrustation thing on wiping spheroid and the valve seat keeps the excellent sealing between spheroid and the valve seat voluntarily.
In the rotary course of V-type ball valve core; Gas powder medium constantly changes through the actual internal area of spool; But because V-type ball valve wicking surface has the vee-type breach; Rotation in any case, the shape at circulation interface remains triangle, so V-type ball valve core has the inherent flow characteristic, of an approximate equal percentage and up to the regulating ratio of [sesame 1 is respected by department] 100:1; Can in the variation range of the wide width of cloth, accurate control be provided, guarantee that valve all has good adjusting function under various apertures.
In such scheme, described upper valve rod passes the bonnet, that is arranged at the valve body top, is connected with transmission shaft, and described lower valve rod is coaxial and withstand on the bottom flange with upper valve rod.
Principle of the present invention is to adopt the spool of V-type ball valve core as valve, and along with the rotation of spheroid, actual internal area constantly changes, but the shape at circulation interface remains triangle, thereby realizes the regulating action of valve.
The invention has the beneficial effects as follows:
1, V-type ball valve core has the inherent flow characteristic, of an approximate equal percentage, can in the variation range of the wide width of cloth, accurate control be provided.
2 wear-resistant ceramic liners have prolonged service life of equipment greatly, are applicable to the dielectric property of coal spraying pipeline.
3 adopt hard sealing structure, and impurity such as ability cut fibres have self-cleaning function, avoid the valve stuck phenomenon to take place.
4 select air-actuator for use, satisfy the fire-proof and explosion-proof requirement in working space.
5 volumes are little, in light weight, simple in structure, good seal performance, are a kind of valves that real high efficiency is controlled state of arts.
