Abstract
The utility model relates to the technical field of machinery, in particular to a novel high-temperature super wear-resisting shear valve. The novel high-temperature super wear-resisting shear valve is characterized in that the pipe wall of an inlet runner at the outer end of a movable valve seat is provided with an annular groove; a corrugated pipe is embedded in the annular groove; the inner end of the corrugated pipe is abutted with the outer end of the movable valve seat; and the pipeline direction of the corrugated pipe is consistent with the direction of the inlet runner. Compared with the prior art, the novel high-temperature super wear-resisting shear valve has the advantages that the stress of a medium to the valve seat is balanced, a floating effect is good, the requirement on a sealing surface is not high, and a sealing junction surface is short. Under the action of high temperature, the corrugated pipe floats directionally along the axis, and the valve seat cannot be easily jammed in the floating process, i.e. the high-temperature floating effect is good; the corrugated pipe, a valve body and the valve seat are integrally designed, bad media, such as various viscous sizes, solid-liquid two-phase suspensions, continuous fiber-contained or grain-contained liquid and gases, are not easy to enter between the valve seat and the valve body, so that the valve seat cannot be influenced, therefore, the novel high-temperature super wear-resisting shear valve is comparatively suitable for the bad media, such as various viscous sizes, the solid-liquid two-phase suspensions, the continuous fiber-contained or grain-contained liquid and gases.
Description
Technical field
The utility model relates to field of mechanical technique, the ultra wear-resisting shear valve of specifically a kind of new type high temperature.
Background technique
Be applicable in the existing technology that the valve base sealing structure of the valve of its use is comparatively general under the various abominable medium operating conditions such as viscous slurry, corrosive liquids or gas of oil, chemical industry, electric power, environmental protection industry (epi).Because valve base sealing structural type is the key of valve seal performance, can directly influence the safe and reliable operation of pipe-line system.The valve base sealing structure of now general gate valve adopts the structure of plane fixed valve base 2-1, referring to Fig. 1, or the structure of two-dimensional activity type valve seat 2-2, referring to Fig. 2 and Fig. 3.
The a pair of valve base sealing structure of general existing technology gate valve can be formed or be made up of the two-dimensional activity type valve seat among Fig. 2 by Fig. 1 midplane fixed valve base structure, also can be by plane fixed valve base structure and plane active type valve seat construction supporting composition.This valve base sealing structure can be used for comprising the gate valve of the sealing configuration of wedge-type and flat Single disc or double-flashboard.
When a pair of valve base sealing structure of gate valve was formed by Fig. 1 midplane fixed valve base structure, in opening process, the solid particle in the medium was prone to each sealing surface of erosion valve; The toughness jelly is prone to be bonded on each sealing surface of valve, and long fibre shape material and particle etc. are prone to be stuck between each sealing surface; The long-term contact corrosion property medium of each sealing surface also can be prone to produce phenomenons such as erosion, oxidation, decortication, incrustation, causes sealing surface to damage; When under high temperature or low temperature environment, using, because there is not the temperature expansion compensation, valve opening or be prone to take place the jam phenomenon when closing.
When a pair of valve base sealing structure of gate valve by plane fixed valve base structure and plane active type valve seat construction during supporting the composition; Solid particle in the medium, toughness jelly, Korrosionsmedium can get into from the valve seat back side between valve body and the valve seat phenomenons such as the easy generation burn into of seal ring, spring incrustation the movable valve seat; Cause movable valve seat inefficacy, stuck, sealing surface is revealed; When high temperature or low temperature environment used down, because the sealing surface gap requires height, sealed faying face was long, and valve seat floats along the axis non-directional, and valve seat is stuck easily in location free procedure.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes existing technology, adopts bellows that its valve base sealing structure is improved to the shear valve in the gate valve.
For realizing above-mentioned purpose; The utility model designs the ultra wear-resisting shear valve of a kind of new type high temperature; Comprise valve body, movable valve seat, flashboard, seating spring, spring seat, check ring, bellows; Said movable valve seat is located between flashboard and the valve interior wall, it is characterized in that: establish an annular groove on the tube wall of the inlet channel of the outer end of movable valve seat, be embedded bellows in the annular groove; The outer end of the movable valve seat of inner butt of bellows, the duct orientation of said bellows is consistent with the direction of inlet channel.
The bellows two ends are provided with seal ring respectively and between the tube wall of movable valve seat, inlet channel.
Movable valve seat is L shaped; Left V-arrangement valve seat packing layer, packing press ring, spring assembly, right V-arrangement valve seat packing layer are established from outside to inside successively along the direction of inlet channel in L shaped movable valve seat and the gap between the valve interior wall, and described spring assembly is employed in and is embedded the seating spring composition in the spring seat.
The left end of described packing press ring is protruding left arrow shaped, and the right-hand member of packing press ring is a vertical plane, the left end of packing press ring and left nested connection of V-arrangement valve seat packing layer.
Described spring seat is the pipe shape of left end opening, right-hand member sealing, and the right-hand member of spring seat is protruding to the right arrow shaped, the right-hand member of spring seat and right nested connection of V-arrangement valve seat packing layer.
The utility model is compared with existing technology, and medium is to the valve seat stress equalization, and it is effective to float, and sealing surface is less demanding, and sealed faying face is short; Because seal request is not high, junction plane is short, and bellows floats along axis orientation under high temperature action, and valve seat is difficult for stuck in location free procedure, and high temperature floats effective; Bellows and valve body and valve seat are global design; Various viscous slurry, solid-liquid two phase suspension, the abominable medium such as liquids and gases that contains long fibre or particle are difficult for getting between valve seat and the valve body valve seat are exerted an influence, so this valve is applicable to various viscous slurry, solid-liquid two phase suspension, contains the abominable media such as liquids and gases of long fibre or particle.
