Abstract
The invention discloses a large-flux wafer type high-performance butterfly valve which comprises a valve body, a valve plate, a valve seat, an upper valve shaft, a lower valve shaft and a valve body pressing plate, wherein the valve body pressing plate and the valve body are fixedly connected through connecting bolts arranged in a circular manner; the valve seat is embedded between the valve body and the valve body pressing plate; the outer diameter of the valve body pressing plate is the same as the outer diameter of the valve port of the valve body; and a sealing gasket clamped and located between the valve body and a pipeline connecting flange integrally covers the inner rings of the connecting bolts of the valve body pressing plate. According to the large-flux wafer type high-performance butterfly valve, the outer diameter of the valve body pressing plate is the same as the outer diameter of the valve port of the valve body, the excircle of the valve body pressing plate is as large as the excircle of the valve body, and the connecting bolts can be arranged near the outer edge, so that during design, the diameter of the inner cavity of the valve seat can be enlarged, the medium flux of the valve is increased, and the flow capacity of the valve is improved, namely, compared with a valve with the same appearance and volume, the large-flux wafer type high-performance butterfly valve has the advantages that the effective diameter is larger, and mediums can smoothly pass through the valve; and the connecting bolts are extended outwards, so that the interference with the sealing gasket is avoided, and the overall sealing performance is improved.
Description
Technical field
The present invention relates to butterfly valve technical field, particularly relate to a kind of large flux wafer type high-performance butterfly valve.
Background technique
Butterfly valve is widely used in the fluid means control apparatus of the various occasions such as oil, chemical industry, metallurgy, electric power, weaving, light industry, machine-building, building and defence and military.Valve plays vital effect in whole equipment and system, and the inefficacy of butterfly valve can cause system, equipment normally to work, and even can cause the generation of catastrophic failure time serious, and this just requires that butterfly valve must have very high reliability.
Simultaneously, butterfly valve is as a disabling mechanism, when conducting, also inevitably convection cell forms impact, especially erecting bed contract bundle valve volume can not excessive time, the negotiability of valve is restricted, bring impact to the normal conveying of fluid, the setting of the connecting bolt of valve body pressing plate simultaneously also can have influence on the sealability of seal ring.
Summary of the invention
The object of the invention is the technological deficiency for existing in prior art, and a kind of large flux wafer type high-performance butterfly valve is provided.
The technological scheme adopted for realizing object of the present invention is:
A kind of large flux wafer type high-performance butterfly valve, comprise valve body, valve plate, valve seat, upper valve shaft, lower valve shaft and valve body pressing plate, valve body pressing plate is fixedly connected with the connecting bolt of valve body by rounded Boulez, described valve seat is embedded between valve body and valve body pressing plate, described valve body pressing plate is identical with the valve port external diameter of described valve body, and the gasket seal entirety of clamping position between valve body and pipeline coupling flange covers the connecting bolt inner ring of valve body pressing plate.
Described valve plate back spherically shape and intermediate portion without propeller boss.
Described valve seat is PTFE material.
Valve plate back designs has boss, and body cavity is designed with boss block, valve plate close time boss and boss block exist parallel clearance 1-2mm with prevent valve plate cross position close.
Compared with prior art, the invention has the beneficial effects as follows:
Valve body pressing plate of the present invention is identical with the valve port external diameter of described valve body, by equally large with valve body cylindrical for valve body pressing plate cylindrical, connecting bolt can outerly be arranged, and then during design, valve base cavity latus rectum just can become large, increase the rate-of flow of valve equally, improve the negotiability of valve.That is, under equal apparent volume, effective drift diameter of the present invention can be larger, ensures that medium passes through smoothly.Meanwhile, by connecting bolt to extending out, avoiding the interference with gasket seal, improve overall sealing performance.
Accompanying drawing explanation
Figure 1 shows that the structural representation of large flux wafer type high-performance butterfly valve of the present invention;
Figure 2 shows that assembling state cross sectional representation;
Figure 3 shows that the close-up schematic view shown in Fig. 2.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1-Figure 3, large flux wafer type high-performance butterfly valve of the present invention comprises valve body 1, valve plate 2, valve seat 3 and valve body pressing plate 4, valve body pressing plate 4 is fixedly connected with the connecting bolt 5 of valve body 1 by rounded Boulez, described valve seat 3 is clamped between valve body and valve body pressing plate, described valve body pressing plate 4 is identical with the valve port external diameter of described valve body 1, and gasket seal 6 entirety of clamping position between valve body and pipeline coupling flange 8 covers the inner ring of the connecting bolt of valve body pressing plate 4.Specifically, valve body and the sealing mechanism of pipeline coupling flange comprise the centering ring 7 be fixedly connected with valve body, are integrally formed in the gasket seal 6 in centering ring, and it no longer launches to describe at this similarly to the prior art.
Valve body pressing plate of the present invention is identical with the valve port external diameter of described valve body, by equally large with valve body cylindrical for valve body pressing plate cylindrical, connecting bolt can outerly be arranged, and then during design, valve base cavity latus rectum just can become large, increase the rate-of flow of valve equally, improve the negotiability of valve.That is, under equal apparent volume, effective drift diameter of the present invention can be larger, ensures that medium passes through smoothly.Meanwhile, by connecting bolt to extending out, avoiding the interference with gasket seal, improve overall sealing performance.
Further, decrease the thickness at valve plate center, simultaneously valve plate adopts back spherically shape and intermediate portion, without the design of propeller boss, when ensureing valve shaft and valve plate intensity, increasing the rate-of flow of valve, improve the negotiability of valve.
Preferably, described valve seat is PTFE material, and valve seal relies on the extrusion-deformation of valve plate and valve seat to realize, PTFE have certain flexible while, there is very strong corrosion resistance, can ensure for multiple occasion.
Preferably, valve plate back designs has boss, and body cavity is designed with boss block, valve plate close time boss and boss block exist parallel clearance 1-2mm with prevent valve plate cross position close.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
