Abstract

The invention belongs to the technical field of valves, and particularly relates to a pipe clamp valve. The pipe clamp valve comprises a valve body with a built-in flow pipe, and a medium flows in from an inlet of the flow pipe and is discharged from an outlet of the flow pipe; the valve body is further provided with a switch part used for controlling the flow pipe to be opened and closed; the pipe clamp valve is characterized in that the flow pipe is a double-layer pipe body and comprises a lining pipe serving as an inner pipe body and a protection pipe serving as an outer pipe body, and thelining pipe and the protection pipe are coaxially arranged in a sleeving manner; and the valve body is further provided with a sensing assembly used for monitoring whether media exist in a sealing gapbetween the lining pipe and the protection pipe or not. According to the pipe clamp valve, not only can the function of preventing medium leakage be achieved when the lining pipe is broken, but alsothe purpose of on-line detection of the leakage condition of the lining pipe can be achieved, so that maintenance personnel can be timely reminded of troubleshooting as soon as possible, and the use safety and reliability of the pipe clamp valve can be effectively guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of valves, and in particular relates to a pipe pinch valve. Background technique

[0002] The pinch valve is a device used to control the directional pressure and flow of the fluid in the fluid system. It is an important control component in the pipeline fluid delivery system. It is widely used in many fields such as chemical industry, food, medical equipment, electronic industry, and sewage treatment. Applications. The traditional pinch valve relies on manual wheel rotation to control the two splints to squeeze in the same direction or move away from each other to release the liner, so as to achieve the purpose of cutting off, releasing pressure or throttling. On the one hand, since the two splints of the traditional pinch valve need to be operated independently, a large amount of action space is required, and the site occupancy rate is relatively high. On the axis of the pipe, the above-mentioned dual in...

Embodiment Construction

[0037] For ease of understanding, combined here Figure 1-4 , the concrete structure and working mode of the present invention are further described as follows:

[0038] The specific structure of the present invention is as Figure 1-4As shown, the main structure includes a valve body 10, a switch part, a flow pipe 20 and a reversing assembly. Among them: the valve body 10 includes the middle valve pipe 11 and the flange end caps 12 which are located at both ends and form a flange fit; the flow pipe 20 consists of a liner pipe 21 as the inner casing and a protective pipe as the outer casing. 22 together constitute. The direction-changing assembly includes a traction rope 62 and a direction-changing wheel 61 to realize the synchronous movement of the power plate 42 at the upper pressing assembly and the follower plate 52 at the lower pressing assembly toward and away from each other.

[0039] Specific to figure 1 In the shown structure, it can be seen that: the two ends of ...
