Detailed Description
The utility model provides a safe type ejection of compact butterfly valve. The technical solution of the present invention will be described in detail below with reference to the accompanying drawings so as to be easier to understand and grasp.
A safety type discharging butterfly valve is shown in figures 1 to 5 and comprises an annular valve seat 1, a flexible valve plug 2 for opening and closing a valve channel of the annular valve seat 1 and a rotary driving source 3 for driving the flexible valve plug 2 to rotate.
The flexible valve plug 2 has a disk-shaped structure, a rotating shaft 4 is radially disposed and is connected to the rotary drive source 3 through the annular valve seat 1, the flexible valve plug 2 has wing portions 5 located on both sides of the rotating shaft 4, and as shown in fig. 5, any wing portion 5 has a structure that is radially narrowed in a direction perpendicular to the rotating shaft 4.
The specific implementation process and principle description are as follows:
the discharging butterfly valve is mainly used for crushing material discharging, and the flexible valve plug 2 is driven by the rotary driving source 3 to carry out open-close control on a valve channel so as to realize stopping material and discharging operation.
It should be noted that, by the design of the structure of the wing portion 5 which is gradually narrowed, a rotation avoiding space is provided, so that the rotation displacement of the flexible valve plug 2 is smooth and the blocking-up matching is more reliable and effective.
Adopt the design of flexible valve plug 2, when blocking the operation, there is the condition of partial crushing granule embedding between flexible valve plug 2 and valve channel, and flexible valve plug 2 itself possesses certain flexible deformation power for crushing granule can not cause the fit clearance, has improved sealing performance, and can maintain the seal performance for a long time. Simultaneously, at operating personnel maloperation in-process, flexible deformation guard action can be played to flexible valve plug 2, can not cause great incident.
In one embodiment, as shown in fig. 3 and 5, the flexible valve plug 2 is provided with a rectangular channel 6 with a rectangular cross section for loading the rotating shaft 4, and the rotating shaft 4 is provided with a transmission rod end which is limited and arranged in the rectangular channel.
Through the design of rectangular channel 6, can satisfy the stability demand of rotation torque transmission promptly, can not appear the moment of torsion too big rotation axis 4 and the 6 dislocation phenomenon of rectangular channel that lead to, increased structure cooperation reliability.
In one embodiment, the flexible valve plug 2 is a polyurethane valve plug. The wear-resistant rubber belt has certain elastic deformation and very reliable wear resistance, and meets the actual use requirements.
In a particular embodiment, as shown in fig. 3 to 5, the wing 5 comprises a top inclined surface 51 and a bottom inclined surface 52 arranged in mirror symmetry.
Make the sealed outer fringe and the valve channel cooperation of flexible valve plug 2 more reliable stable promptly, at rotatory in-process, the space equilibrium is dodged to top inclined plane and bottom inclined plane, and flexible valve plug 2 rotary displacement is more smooth and easy reliable.
Of course, in order to match and further eliminate the rotation resistance of the flexible valve plug 2, the outer edges of the top end surface and the bottom end surface are provided with outer edge chamfers, so that the rotation resistance can be further reduced, and the energy consumption is reduced.
In one embodiment, a sealing fit mechanism is provided between the annular valve seat 1 and the rotating shaft 4.
Specifically, the annular valve body 1 has a passage through which the rotary shaft 4 passes, and the seal engagement mechanism is provided in a fitting gap between the rotary shaft 4 and the passage, and may be a seal such as a seal bush.
Can discover through the above description, the utility model relates to a safe type ejection of compact butterfly valve through discoid flexible valve plug design for ejection of compact butterfly valve volume is less, easily carries on and ejection of compact control, and flexible valve plug possesses better wearability and elasticity simultaneously, improves the operation security, has prolonged life. The flexible plug body and the valve channel have the sealing performance of being matched very reliably, the supply requirement of negative pressure blocking can be met, meanwhile, the required power is small, and the power requirement and the energy consumption of a driving source are reduced. The whole design is simple and ingenious, the manufacturing cost is low, and the method is suitable for popularization and application.
