Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0032] An embodiment of a novel channel on-off control switch of the present invention, such as Figure 3 to Figure 6 As shown, the orientation shown in the figure is taken as an example for illustration. The switch includes a main housing 1, which is provided with an interface part, a sealing part, and a locking part. The interface part is used to connect upstream and downstream pipelines or system interfaces; the sealing part is used to block the flow of liq...

Abstract

A novel flow channel on-off control switch comprises a main shell, a liquid flow channel is arranged in the main shell, the liquid flow channel comprises an outer section and an inner section, a sealing rod is arranged on the wall of the main shell in a sliding and penetrating mode, a limiting end of the sealing rod is used for controlling on-off of the liquid flow channel, the other end of the sealing rod is located on the outer side of the main shell and fixedly connected with a handle, and an elastic component is arranged between the end face of the handle and the outer wall of the main shell; and the outer side of the handle is provided with an annular boss in a sleeving mode, the annular boss is provided with a nut in a sleeving mode and in a sliding mode, an elastic component is arranged between the nut and the outer wall of the main shell, first through holes are distributed in the annular boss, and locking pieces are embedded in the first through holes in a sliding mode. Compared with the prior art, the switch has the beneficial effects that sealing points are concentrated, a sealing rubber ring is mainly used for closing, an isolation rubber ring is used for opening, a stable and reliable O-shaped ring is adopted for radial sealing, the leakage risk of multi-point sealing of valve products is avoided, meanwhile, the structure is simple, and the size of the valve can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of valves, and in particular relates to a novel flow channel on-off control switch. Background technique [0002] The existing valve schemes in the market are basically ball valve or gate valve schemes, and the two schemes are similar. Taking ball valves as an example, ball valves have the function of connecting or disconnecting pipelines. Such as figure 2 As shown, when the ball valve is in the disconnected state, the ball valve forms a seal through the compressed seals between the inner ball core 17 and the interface housings 16 at both ends, so that the pipeline is in the disconnected state. Turn the handle 13 at the upper end of the ball valve by 90° to drive the middle transmission key 14 to rotate, and the transmission key 14 drives the ball core 17 to rotate. figure 1 shown. The ball valve of this structure is connected to the pipeline to achieve the purpose of connecting or disconnecting the flow...
