Abstract
The invention provides a normally-open pneumatic pipe clamp. For guaranteeing the safety of the technical process, the force stimulation action of a switching valve for an energy-containing liquid material conveying pipeline during the action of a valve element should be reduced as much as possible, so that a pipe clamp valve is commonly selected. For the commonly used pipe clamp valve, a sleeve is arranged in a valve body, so that a user cannot visually observe the wear degree of the sleeve and whether the sleeve leaks easily, so that the common pipe valve has certain hidden dangers when energy-containing liquid materials are conveyed; and under unforeseen circumstances of the existing pipe clamp valve, if the driving force loses (such as the cutoff of a power supply or an air source), the opening and closing states of the valve are difficult to determine, and therefore, accidents may be caused. The normally-open pneumatic pipe clamp is opened through a spring force for overcoming the problems. The normally-open pneumatic pipe clamp comprises a slide sleeve (1), a guide shaft (2), a connecting plate (3), a shell (4), an adjusting pin bolt (5), a spring (6), an air cylinder (7), an air cylinder mounting plate (8), a pressure head (9) and a limiting sleeve (10).
Description
Technical field
The invention belongs to explosive wastewater Auto-control of the process field, relate to containing can liquid material conveying control
A kind of pneumatic tubing clip of system.
Background technology
Containing liquid material pipeline conveying on-off control safety being had strict requirements.On the one hand requirement
Spool is when action, and the power produced the liquid material containing energy as far as possible stimulates little, the most typically selects pipe
Folder valve；On the other hand, from the angle of technique, it is desirable to valve in the case of accident (such as power supply or gas
Source cuts off) can keep the folding condition that determines, such as: employing pipeline carries nitroglycerine to be carried out
During charging, it is desirable in the case of accident, switch valve is kept closed stopping nitroglycerine charging,
To detect fault, it is to avoid dangerous expansion further；Pipeline for evacuation (contains in pipeline
Energy liquid material steam) folding control, it is desirable in the case of accident, switch valve remains on,
So that container is carried out pressure release, out of service.Conventional pipe clip valve is arranged on valve inner due to sleeve pipe,
