Abstract
The utility model relates to a T-shaped elastic valve seat sealing structure of a V-shaped adjusting ball valve. The T-shaped elastic valve seat sealing structure of the V-shaped adjusting ball valve comprises a valve body, a pressing ring, a supporting ring, a first metal graphite ring, a T-shaped elastic valve seat, a second metal sealing ring and a valve ball. The T-shaped elastic valve seat is installed between the second metal sealing ring and the first metal graphite ring, and the supporting ring and the pressing ring are sequentially and laterally installed on the valve body. The pressing ring tightly presses the supporting ring to enable the T-shaped elastic valve seat and the valve ball to be matched to form a sealing pair. The second metal sealing ring is installed in a step hole in the valve body, and the first metal graphite ring is installed on a step shaft of the supporting ring to form an axial sealing structure. Even if the T-shaped elastic valve seat sealing structure of the V-shaped adjusting ball valve operates for a long time in a pressed mode, the situation that sealing fails due to the fact that the graphite ring moves and disengages can be avoided; the T-shaped elastic valve seat sealing structure can be attached to the sealing surface of the valve ball through the elasticity of the T-shaped elastic valve seat sealing structure itself, and therefore ball surface abrasion is reduced; the operation stability of the V-shaped adjusting ball valve at high temperature can be improved, and it is guaranteed that a device can run safely and efficiently.
Description
Technical field
The utility model relates to a kind of V-type and regulates the T-shaped elastic seat sealing configuration of ball valve, can realize valve effective stabilized seal at high temperature, belongs to instrument control technique field.
Background technique
V-type regulates ball valve owing to can forming effective shear action between its valve seat and valve ball, the very applicable industrial control occasions such as papermaking under mesolow operating mode, chemical industry, metallurgy that are applied to, are specially adapted to the fluid of suspended particulate and the automatic adjustings of dense, turbid slurry flow body medium such as paper pulp in slurrying, paper production process, plain boiled water, black liquor, white liquid.
In current prior art, V-type regulates the valve seat construction of ball valve conventionally to adopt wavy spring or butterfly spring compensation, O type circle or graphite annulus sealing configuration; In the structure of wavy spring compensation, the pretightening force of wavy spring can change because of the variation of trim ring pad amount of deformation, causes the working depth of wavy spring wayward, causes valve shaft to unbalance stress; And butterfly spring is owing to itself having larger active force, use to regulate on ball valve in the V-type of underload operating mode, the as easy as rolling off a log impaired valve seat that even pushes of Sealing that causes because thrust is excessive causes valve ball micro-deformation.The sealing of O type circle is that V-type regulates the most general structure of ball valve, but due to the narrow limitation of O type circle material, conventionally can only be used for the occasion of-25-200 °, the occasion higher in temperature used graphite annulus sealing configuration, but the easy compressive deformation of traditional graphite annulus, turnover rate is frequent.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, regulate the drawback of ball seat sealing configuration for solving traditional V-type, provide a kind of V-type to regulate the T-shaped elastic seat sealing configuration of ball valve, be intended to improve the working stability under the high temperature that V-type regulates ball valve, assurance device safety, operation efficiently.
The technological scheme providing according to the utility model, V-type regulates the T-shaped elastic seat sealing configuration of ball valve to comprise valve body, trim ring, support ring, the first metallic graphite carbon ring, T-shaped elastic seat, the second metallic packing ring and valve ball; Described T-shaped elastic seat is arranged between the second metallic packing ring and the first metallic graphite carbon ring, and described support ring, trim ring successively side direction are installed on to valve body; Trim ring compresses support ring, T-shaped elastic seat is coordinated with valve ball and form sealing pair; Described the second metallic packing ring is installed in valve body step hole, and the first metallic graphite carbon ring is installed on support ring Step Shaft, forms axial seal structure.
As further improvement of the utility model, described T-shaped elastic seat adopts the impact briquetting of Inconel high elastic modulus material.
As further improvement of the utility model, described valve body is provided with step hole; Described valve body step hole is provided with pad prepackage space.
As further improvement of the utility model, described the first metallic graphite carbon ring and the second metallic packing ring adopt respectively metal nickel wire composite Seiko braiding structure.
As further improvement of the utility model, described support ring is provided with Step Shaft; Described support ring Step Shaft is provided with pad prepackage space.
Compared with the prior art the utility model has the following advantages:
1, adopt the second metallic packing ring to be installed in valve body step hole, the first metallic graphite carbon ring is installed on the axial seal structure on support ring Step Shaft, even long-term work can not make graphite annulus generation displacement deviate to cause seal failure yet under pressured state.
2, the T-shaped elastic seat that adopts the punching press of Inconel material to make, can utilize himself elasticity laminating valve ball sealing surface, reduces sphere abrasion; And can be used in 250 ° of-500 ° of operating mode occasions.
3, first, second metallic packing ring adopts metal nickel wire composite Seiko braiding structure, can ensure its sealing reliability at high temperature.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of T-shaped elastic seat.
Fig. 3 is that the A of Fig. 2 is to schematic diagram.
Embodiment
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in Figure 1: V-type regulates the T-shaped elastic seat sealing configuration of ball valve; Comprise the part compositions such as valve body 1, trim ring 2, support ring 3, the first metallic graphite carbon ring 4, T-shaped elastic seat 5, the second metallic packing ring 6, valve ball 7.
Described T-shaped elastic seat 5 is installed between the second metallic packing ring 6 and the first metallic graphite carbon ring 4, described support ring 3, trim ring 2 successively side direction are installed on to valve body 1; Trim ring 2 compresses support ring 3, T-shaped elastic seat 5 is coordinated with valve ball 7 and form sealing pair.The elastic force that T-shaped elastic seat 5 has due to itself, can play bidirectional compensating loading effect; Described the second metallic packing ring 6 is installed in valve body 1 step hole, and the first metallic graphite carbon ring 4 is installed on support ring 3 Step Shafts, forms axial seal structure.
Working principle of the present utility model: in the time that valve is in running order, the pretightening force that support ring 3 is subject to trim ring 2 is pushed T-shaped elastic seat 5 to and produced elastic potential energy, makes T-shaped elastic seat 5 form tight seal with valve ball 7.The second metallic packing ring 6 and the first metallic graphite carbon ring 4 are subject to micro-elastic force of T-shaped elastic seat, can guarantee graphite annulus be not subject to unidirectionally extruded and lost efficacy distortion, improve valve shaft to sealability.
The utility model long-term work under pressured state can not make graphite annulus generation displacement deviate to cause seal failure yet; The elasticity laminating valve ball sealing surface that can utilize himself, reduces sphere abrasion; Can improve V-type and regulate the working stability under the high temperature of ball valve, assurance device safety, operation efficiently.
