Description
Technical field
The present invention relates to valve technology fields, more particularly to a kind of guiding valve.
Background technology
In the industries such as coal chemical industry, silication work, mine metallurgy, power environment protection, there are a large amount of conveying gas solid, liquid to consolidate, gas-liquid-solid
The medium of three-phase, especially in grit mixture condition, it is used at present be mostly hard seal ball valve, butterfly valve, sluice valve, gate valve, insert
The valves such as plate valve more or less have service life not grow, problem difficult in maintenance, and the especially strong operating mode of part erosion is to close
Envelope requires stringent, but there are media sticky, easy caking, easy fouling, easily crystallization or the occasion containing bulky grain, not only washes away sternly
Weight, also often results in the case where various valve blockages are blocked.
By taking most commonly used hard seal ball valve under these current operating modes as an example, concrete analysis is as follows：
(1) for ball valve in opening-closing process, medium easily enters valve chamber, and is accumulated in valve chamber；The meeting when medium temperature reduces
It causes certain media to solidify and locking opening and closing element, therefore easily leads to the serious consequences such as valve is stuck.
(2) and when the granule medium in-line flow at high speed of high rigidity, sealing surface of seat damage or sphere are easily led to
Surface spraying layer falls off, and then influences valve seal effect, when serious, valve seal can be caused to fail.
Sluice valve valve since lumen is full of material, and leads to valve blocking after running a period of time；Slide plate and clamping plate
Between serious wear, while in above system, due to the physicochemical characteristics of fluid, some valves often occur trim or
The damage that runner is seriously washed and cavitates after valve seat in turn results in what the even entire transport system of valve cannot all run well
Failure.
Butterfly valve, gate valve, gate valve etc., due also to the bias current of medium fluid is serious, are very easy in addition to sealing performance is not good
Runner is washed away, pipeline is caused to need to be replaced frequently.
Therefore need one kind can do regulating valve but also do switch valve, lumen no backup, should not blocking, medium do not wash away
The valve of sealing surface, to ensure the long-term operation of system.
Invention content
The object of the present invention is to provide a kind of guiding valves, realize in various slurries, gas-solid granule medium, gas-solid-liquid three-phase medium
Not interim card, the blocking of valve, sealing is permanently effective, improves valve service life.
To achieve the goals above, technical solution of the invention is：
A kind of guiding valve, including plectane valve seat and sliding block and valve rod, valve body, upper mounting plate, valve body liner, flange；The valve
It is equipped with valve body liner in vivo；The lower end of the valve rod and the upper end of sliding block are connected；The sliding block can be along the one of plectane valve seat
Side moves up and down, and generates flat seal with the edge in the runner hole of plectane valve seat, realization throttles to fluid, opened and closed
It is disconnected.
Guiding valve of the present invention, wherein the plectane valve seat is circular plate shape, is fixed on valve body.
Guiding valve of the present invention, wherein the runner hole is arbitrary shape.
Guiding valve of the present invention, wherein the shape in the runner hole be round, rectangular, rectangle, trapezoidal, triangle,
V-type, U-shaped or any one fan-shaped.
Guiding valve of the present invention, wherein the runner hole is made of throttle orifice.
Guiding valve of the present invention, wherein the material of the plectane valve seat is metal, ceramics or cermet composition.
Guiding valve of the present invention, wherein the sliding block is solid parts, using the shape in the runner hole of cooperation plectane valve seat
Shape.
Guiding valve of the present invention, wherein the shape of the sliding block is round, rectangular, rectangle, trapezoidal, triangle, V
Type, U-shaped or any one fan-shaped.
Guiding valve of the present invention, wherein the material of the sliding block is metal, ceramics or cermet composition.
Guiding valve of the present invention, wherein the sealing surface in the runner hole carries out hardened artiwear processing or using ceramics
Wear-resistant material.
Compared with the existing technology, protrusion effect of the invention is：
It is a stream of the all-pass without any blocking in the guiding valve of the present invention after the sealing surface of fixed disc valve seat and sliding block
Road, will not accumulation medium cause caking, crystallization cause valve blockage.Medium is in the runner hole of fixed disc valve seat by that will not rush
Brush sealing surface can guarantee the long-term operation of system.
Explanation and specific embodiment are described further guiding valve of the present invention below in conjunction with the accompanying drawings.
