Abstract
The invention discloses a telescopic butterfly valve with an elastic structure, which comprises a valve body and a flange connected with one side of the valve body, wherein the valve body is connected with the flange through the elastic structure; the elastic structure comprises a circular elastic mat connected with the valve body, and an elastic pressure plate used for fixing the elastic mat; the flange is provided with a neck; the outer diameter of the neck of the flange is the same as the inner diameter of the circular elastic mat; the elastic pressure plate is connected with the valve body through a second screw; the flange is connected with the valve body through a first screw. As the elastic structure is arranged between the valve body and the flange, when the weight of a pipeline connected with the flange is higher, the connection part deforms within an acceptable range, which not only improves the bearing capability of the connection part, but also can maintain the sealing effect of the connection part.
Description
Technical field
The invention belongs to valve technology field, relate in particular to a kind of telescopic butterfly valve that has elastic structure.
Background technique
Valve is the controlling component in the fluid delivery system, have by, adjusting, water conservancy diversion, prevent functions such as adverse current, voltage stabilizing, shunting or overflow pressure release.The valve that is used for liquid control system, from the simplest stop valve to very complicated robot control system(RCS) used various valves, its kind and specification are quite various.Valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.Valve also is divided into cast iron valve, cast steel valve, stainless valve etc. according to material.
Butterfly valve is Flap valve again, is a kind of modulating valve simple in structure, also can be used for the switch control of low pressure pipeline medium simultaneously.Butterfly valve refers to that closure member (flap or butterfly plate) is disk, centers on a kind of valve that valve shaft rotates to reach open and close, and main rising cut off and throttling action on pipeline.The butterfly valve open-shut device is a discoidal butterfly plate, and the axis around himself in valve body rotates, thereby reaches the purpose that opens and closes or regulate.
Butterfly valve comprises valve rod, valve body, valve plate, valve seat, in the prior art, when butterfly valve one end connects by flange, and the pipeline weight that connects of this end is bigger the time, the joint easy deformation of butterfly valve and flange, thus the sealing effect that butterfly valve is connected with flange influenced.
Summary of the invention
The purpose of this invention is to provide a kind of telescopic butterfly valve that has elastic structure, to solve the problems referred to above that prior art exists.
In order to finish the object of the invention, the invention provides a kind of telescopic butterfly valve that has elastic structure, comprise valve body, with valve body one side flange connecting, described valve body is connected by elastic structure with described flange.
Wherein, described elastic structure comprises that the annular resilient pad that is connected with valve body, spring bearer plate, the described flange that is used for fixing described cushion are hubbed flange, the neck external diameter of described flange equates with the internal diameter of described annular resilient pad, described spring bearer plate is connected with described valve body by second screw, and described hubbed flange is connected with described valve body by first screw.
The present invention makes that by between valve body and flange elastic structure being set when the weight of working as the flange connections road was bigger, the joint produced the distortion in the tolerance interval, has both improved the strength of joint, can keep the sealing effect of joint again.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
As shown in Figure 1, in order to finish the object of the invention, the invention provides a kind of telescopic butterfly valve that has elastic structure, comprise valve body, with valve body one side flange connecting, described valve body is connected by elastic structure with described flange.
Wherein, described elastic structure comprises that the annular resilient pad that is connected with valve body, spring bearer plate, the described flange that is used for fixing described cushion are hubbed flange, the neck external diameter of described flange equates with the internal diameter of described annular resilient pad, described spring bearer plate is connected with described valve body by second screw, and described hubbed flange is connected with described valve body by first screw.
Need to prove that spring bearer plate closely is connected with described valve body by second screw; Described hubbed flange connects by the described valve body of first screw, the one or both ends of described first screw are provided with nut, has certain activity after described first screw is fixing, described certain activity refers to, when the flange the other end is connected with when surpassing certain threshold values weight, the joint of described valve body and described hubbed flange can be out of shape within the specific limits, be specially bending, described certain limit is acceptable, both guarantee to improve the bearing capacity of joint, and can guarantee sealing effect again.
The present invention makes that by between valve body and flange elastic structure being set when the weight of working as the flange connections road was bigger, the joint produced the distortion in the tolerance interval, has both improved the strength of joint, can keep the sealing effect of joint again.
Above-mentioned only is embodiment of the present invention, for those of ordinary skill, under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, and these improvements and modifications also should be considered as protection scope of the present invention.
