Abstract
The utility model discloses a big flux butt clamp formula high performance butterfly valve, including valve body, valve plate, disk seat, upper valve shaft, lower valve shaft and valve body clamp plate, valve body clamp plate and valve body be by the connecting bolt fixed connection who is circular boulez, the disk seat inlay between valve body and valve body clamp plate, the valve body clamp plate with the valve port external diameter of valve body the same, the seal gasket of clamping position between valve body and pipeline flange is whole to be covered at the connecting bolt of valve body clamp plate inner circle. The utility model discloses a valve body clamp plate with the valve port external diameter of valve body the same, with valve body clamp plate excircle equally big with the valve body excircle, connecting bolt can lean on outer the setting, and then design time disk seat inner chamber latus rectum just can the grow, has increased the medium flow of valve equally, has improved the negotiability of valve. Promptly, under the equal outward appearance volume, the utility model discloses an effective latus rectum can be bigger, guarantees that the medium passes through smoothly. Outwards expand connecting bolt, avoided with seal gasket's interference, improved whole sealing performance.
Description
Technical field
This utility model relates to butterfly valve technical field, particularly relates to a kind of big flux wafer type high-performance butterfly valve.
Background technology
Butterfly valve is widely used in the fluid means control equipment 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 results even in the generation of catastrophic failure time serious, and this just requires that butterfly valve must have the highest reliability.
Simultaneously, butterfly valve is as a disabling mechanism, when conducting, the most inevitably convection cell constitutes impact, especially mounting location constraint valve volume can not excessive time, the negotiability of valve is restricted, bringing impact to the normal conveying of fluid, the setting of the connecting bolt of valve body pressing plate simultaneously also influences whether the sealing property of sealing ring.
Utility model content
The purpose of this utility model is for technological deficiency present in prior art, and provides a kind of big flux wafer type high-performance butterfly valve.
Be the technical scheme is that by realizing the purpose of this utility model
A kind of big flux wafer type high-performance butterfly valve, including valve body, valve plate, valve seat, upper valve shaft, lower valve shaft and valve body pressing plate, valve body pressing plate is connected by the connecting bolt of rounded Boulez is fixing with valve body, 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 clamping position gasket seal entirety between valve body and pipeline coupling flange covers the connecting bolt inner ring at valve body pressing plate.
Described valve plate back spherically shape and mid portion are without propeller boss.
Described valve seat is PTFE material.
Valve plate back designs has boss, body cavity to be designed with boss block, and when valve plate is closed, boss and boss block exist parallel clearance 1-2mm to prevent valve plate from crossing position closedown.
Compared with prior art, the beneficial effects of the utility model are:
Valve body pressing plate of the present utility model is identical with the valve port external diameter of described valve body, valve body pressing plate cylindrical is the biggest with valve body cylindrical, and connecting bolt can outer be arranged, and then during design, valve base cavity latus rectum just can become big, 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 utility model can be bigger, it is ensured that medium passes through.Meanwhile, by connecting bolt to extending out, it is to avoid with the interference of gasket seal, improve overall sealing performance.
Accompanying drawing explanation
Fig. 1 show the structural representation of big flux wafer type high-performance butterfly valve of the present utility model；
Fig. 2 show assembling state cross sectional representation；
Fig. 3 show a portion close-up schematic view shown in Fig. 2.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
As shown in Figure 1-Figure 3, big flux wafer type high-performance butterfly valve of the present utility model includes valve body 1, valve plate 2, valve seat 3 and valve body pressing plate 4, valve body pressing plate 4 is connected by the connecting bolt 5 of rounded Boulez is fixing with valve body 1, 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, the inner ring of the overall connecting bolt covered at valve body pressing plate 4 of clamping position gasket seal 6 between valve body and pipeline coupling flange 8.Specifically, the sealing mechanism of valve body and pipeline coupling flange includes the centering ring 7 being fixedly connected with the valve body, the gasket seal 6 being integrally formed in centering ring, its similarly to the prior art, the most reinflated description at this.
Valve body pressing plate of the present utility model is identical with the valve port external diameter of described valve body, valve body pressing plate cylindrical is the biggest with valve body cylindrical, and connecting bolt can outer be arranged, and then during design, valve base cavity latus rectum just can become big, 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 utility model can be bigger, it is ensured that medium passes through.Meanwhile, by connecting bolt to extending out, it is to avoid with the interference of gasket seal, improve overall sealing performance.
Further, decreasing the thickness at valve plate center, valve plate uses back spherically shape and mid portion without the design of propeller boss simultaneously, in the case of ensureing valve shaft and valve plate intensity, increases the rate-of flow of valve, improves the negotiability of valve.
Preferably, described valve seat is PTFE material, and valve seal relies on valve plate to realize with the crimp of valve seat, while PTFE has certain elasticity, has the strongest corrosion resistance, can guarantee that for multiple occasion.
Preferably, valve plate back designs has boss, body cavity to be designed with boss block, and when valve plate is closed, boss and boss block exist parallel clearance 1-2mm to prevent valve plate from crossing position closedown.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; on the premise of without departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
