Description
技术领域 technical field
本实用新型涉一种密封性能更好的蝶阀，尤其是一种阀轴与阀板扁形孔无销连接的中线蝶阀。 The utility model relates to a butterfly valve with better sealing performance, in particular to a centerline butterfly valve in which a valve shaft and a flat hole of a valve plate are connected without pins. the
背景技术 Background technique
现有技术中的中线蝶阀包括阀体、阀杆、阀座以及蝶板，目前传统的中线蝶阀的阀轴与阀板连接是通过销子连接，这种连接方式的阀门扭矩大，销子处本身就容易形成泄漏点，密封效果不好，使用寿命短。 The centerline butterfly valve in the prior art includes a valve body, a valve stem, a valve seat and a butterfly plate. At present, the valve shaft of the traditional centerline butterfly valve is connected to the valve plate through a pin connection. The valve torque of this connection method is large, and the pin It is easy to form a leak point by itself, the sealing effect is not good, and the service life is short. the
实用新型内容 Utility model content
本实用新型的目的是提供一种中线蝶阀轴与阀板的扁形孔无销连接。 The purpose of the utility model is to provide a pinless connection between the centerline butterfly valve shaft and the flat hole of the valve plate. the
本实用新型采用以下技术方案解决所述问题。 The utility model adopts the following technical solutions to solve the problem. the
一种中线蝶阀轴与阀板的扁形孔无销连接，包括阀体、阀板、阀板扁形孔及阀轴，其特征是：所述阀板的轴孔为扁形孔，阀轴与阀板的扁形孔无销连接。 A centerline butterfly valve shaft is connected with a flat hole of a valve plate without pins, including a valve body, a valve plate, a flat hole of the valve plate and a valve shaft, and is characterized in that: the shaft hole of the valve plate is a flat hole, and the valve shaft and the valve plate Flat hole pinless connection. the
由于本实用新型阀中线蝶阀轴与阀板的扁形孔无销连接所述的阀轴与阀板的扁形孔连接，取代了现有技术阀轴与阀板连接是通过销子连接的结构方式，因此可以形成无销连接，这种连接传递力矩大，阀轴与阀板的配合精度高，阀门扭矩轻，提高了阀门的使用寿命，密封性能得到进一步提高。 Because the centerline butterfly valve shaft of the utility model valve is connected with the flat hole of the valve plate without a pin, the connection between the valve shaft and the flat hole of the valve plate replaces the structure in which the valve shaft and the valve plate are connected by pins in the prior art, Therefore, a pinless connection can be formed, which has a large transmission torque, high matching precision between the valve shaft and the valve plate, light valve torque, prolongs the service life of the valve, and further improves the sealing performance. the

具体实施方式 Detailed ways
如附图所示，本实用新型公开一种中线蝶阀轴与阀板的扁形孔无销连接，包括阀板1、阀板扁形孔2、阀轴3，阀体4，所述阀板1的轴孔为扁形孔2，阀轴3与阀板1的阀板扁形孔2连接，实现无销连接。 As shown in the drawings, the utility model discloses a pinless connection between the centerline butterfly valve shaft and the flat hole of the valve plate, including the valve plate 1, the flat hole 2 of the valve plate, the valve shaft 3, the valve body 4, and the valve plate 1. The shaft hole is a flat hole 2, and the valve shaft 3 is connected with the valve plate flat hole 2 of the valve plate 1 to realize a pinless connection. the
所述中线蝶阀阀板1的轴孔为扁形孔2，阀轴3与阀板1的连接是通过扁形孔2与阀轴3配合，形成的无销连接。阀轴3与阀板1的扁形孔2采用无销连接，取代了以往常采用的销子连接，可实现阀轴3与阀板1的配合精度高，阀板1与阀体4的配合紧密，可以提高密封效果，增加使用寿命。 The shaft hole of the centerline butterfly valve plate 1 is a flat hole 2, and the connection between the valve shaft 3 and the valve plate 1 is a pinless connection formed by cooperating between the flat hole 2 and the valve shaft 3. The valve shaft 3 and the flat hole 2 of the valve plate 1 adopt a pinless connection, which replaces the usual pin connection, which can realize the high matching precision of the valve shaft 3 and the valve plate 1, and the tight cooperation between the valve plate 1 and the valve body 4 , can improve the sealing effect and increase the service life. the
