Description
Technical field
This utility model relates to a kind of check-valves, particularly relates to a kind of slow closed check damper for natural gas line.
Background technology
The effect of check-valves is to prevent the medium in pipeline from flowing backwards, and is mainly used on the pipeline of medium one-way flow, only permits
Permitted medium to flow to a direction, to try to avert accidents.But, for the slow-closing type non-return of natural gas line in prior art
Valve is due to the long-term low temperature state that is in, and the easy resilience of compression spring is insufficient, thus causes the leakage of natural gas, causes safety
Accident.To this end, it is proposed that a kind of slow closed check damper for natural gas line solves the problems referred to above.
Utility model content
The purpose of this utility model is to solve shortcoming present in prior art, and the one proposed is for natural gas
The slow closed check damper of pipeline.
To achieve these goals, this utility model adopts the technical scheme that
A kind of slow closed check damper for natural gas line, including valve body and the adpting flange being arranged on valve body two ends,
The inside of described valve body is provided with the first spacing ring and the second spacing ring, and described second spacing ring connects cylinder, described cylinder
On be arranged with compression spring, one end of described compression spring offsets with the second spacing ring, and compression spring the other end connect have
Spool, the both sides of described spool connect slide block, the inwall of described valve body is arranged with chute, and spool is by slide block and cunning
Groove is slidably connected, and described spool is provided with annular pressure sensing chip away from the side of compression spring, and annular pressure sensing chip away from
One end of spool is fixedly connected on the first spacing ring, and the outer wall of described valve body is provided with control chip and alarm, described ring
Shape pressure sensitive sheet is connected with control chip by wire, and control chip electrically connects with alarm, and described annular pressure senses
The middle part of sheet is provided with closure plug, and one end of described closure plug is fixed on the middle part of spool, and the other end of closure plug extends to the
In one spacing ring.
Preferably, the inwall of described first spacing ring is inclined to set, and the inwall of outer wall first spacing ring of closure plug
Offset.
Preferably, described chute is arranged between the first spacing ring and the second spacing ring, and the two ends of chute are respectively with
The sidewall of one spacing ring and the second spacing ring offsets.
Compared with prior art, the beneficial effects of the utility model are: by arranging between spool and the first spacing ring
Annular pressure sensing chip, and annular pressure sensing chip is electrically connected with control chip, when annular pressure sensing chip detects compression
During the top power deficiency of spring, control chip can control alarm and send alarm, reminds personnel around to note, and timely to only
Return valve to safeguard, effectively avoid owing to recoil of spring is insufficient, and the problem causing natural gas leaking.
Accompanying drawing explanation
