Abstract
In order to ensure the technological process safety, a switch valve for an energy-containing liquid material conveying pipeline reduces the force stimulating effect as much as possible during valve core action, and a pipe clamp valve is generally selected. For the common pipe clamp valve, a sleeve is arranged inside a valve body, and the conditions of sleeve abrasion degree and whether the leakage exists or not are difficult to be directly observed, so that certain potential safety hazard exists when energy-containing liquid materials are conveyed. For the existing pipe clamp valve, under the unexpected conditions such as driving force loss (such power supply or gas source cutting off), the valve opening state is difficult to determine, and the accident occurrence can be caused. The invention provides a normally closed pneumatic pipe clamp tightly locked by the spring force, and solves the problems. The normally closed pneumatic pipe clamp comprises slide sleeves (1), guide shafts (2), a connecting plate (3), a case (4), regulating pins (5), springs (6), an air cylinder (7), an air cylinder installing plate (8), press heads (9) and position limiting sleeves (10).
Description
Technical field
The invention belongs to explosive wastewater Auto-control of the process field, relate to containing liquid material carrying a kind of gas controlled
Dynamic pipe clamp.
Background technology
Containing liquid material pipeline conveying on-off control safety being had strict requirements.On the one hand require that spool is dynamic
When making, the power produced the liquid material containing energy as far as possible stimulates little, the most typically selects pipe clip valve；On the other hand,
From the angle of technique, it is desirable to valve can keep the folding determined in the case of accident (as power supply or source of the gas cut off)
State, such as: when using pipeline conveying nitroglycerine to feed, it is desirable in the case of accident, switch valve
It is kept closed stopping nitroglycerine charging, to detect fault, it is to avoid dangerous expansion further；For taking out
Pipeline (containing containing energy liquid material steam in the pipeline) folding of vacuum controls, it is desirable in the case of accident, switch valve
Remain on, so that container is carried out pressure release, out of service.Conventional pipe clip valve is arranged on valve due to sleeve pipe
Internal portion, it is difficult to the degree of wear to sleeve pipe, and whether there is leakage and observe intuitively, thus be accordingly used in
During containing energy liquid material conveying, there is certain potential safety hazard；There are driving force loss feelings in the most existing pipe clip valve
Under condition, the state of valve folding is difficult to determine, accident may be caused to occur.
