Problems solved by technology

[0002] The flap valve is a valve with simple structure, relatively mature technology and low cost, so it is widely used, but the flap valve in the prior art cannot limit its maximum flow rate, and other types of valves that can control the flow rate can be replaced. Not only the cost is high, but the structure is not reliable enough, the structure of the flap valve already in use cannot be modified, and the waste is serious

Embodiment Construction

[0018] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0019] The advantage of the flap valve with a flow limiting device of the present invention is that by adding an angle limiting device for adjusting the handwheel to the flap valve in the prior art to limit the rotation range of the adjusting handwheel, the valve control plate can be reached. The purpose of the rotation range, so as to further control the maximum flow.

[0020] Such as figure 1 As shown, a flap valve with a flow limiting device includes a valve body 1, a valve plate 2 and an adjusting hand wheel 3, such as figure 2 As shown, the valve plate 2 is provided with a connecting shaft 21, such as figure 1 As shown, the connecting sha...

Abstract

The invention discloses a flap valve with a flow limiting device. The flap valve comprises a valve body, a valve plate and an adjusting handwheel, the valve plate is provided with a connection shaft, the connection shaft is connected with the valve body in a rotary manner, and one end of the connection shaft is fixedly connected with the adjusting handwheel. The flap valve with the flow limiting device also comprises an adjusting handwheel angle limiting device. The flap valve with the flow limiting device is advantaged in that a flap valve in the prior art is added with the adjusting handwheel angle limiting device to limit the rotation scope of the adjusting handwheel, the rotation scope of the valve plate can be limited, and therefore the maximum flow can be further controlled.

Description

technical field [0001] The invention relates to a flap valve, more precisely a flap valve with a flow limiting device. Background technique [0002] The flap valve is a valve with simple structure, relatively mature technology and low cost, so it is widely used, but the flap valve in the prior art cannot limit its maximum flow rate, and other types of valves that can control the flow rate can be replaced. Not only the cost is high, but also the structure is not reliable enough, the structure of the flap valve already in use cannot be modified, and the waste is serious. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the prior art, thereby providing a method of limiting the rotation range of the adjustment hand wheel by adding an angle limiting device for the adjustment hand wheel to the flap valve in the prior art, which can achieve control The purpose of the rotation range of the valve plate is to further control ...
