Abstract
Provided is a work pressure locking device of a gas regulator. The locking device is characterized in that a locking bar is disposed at the center part of a pressure regulating cover; the locking bar is connected to a matching wire of the pressure regulating cover; the locking bar is movably connected to a lock head in a ball clamping manner; the locking bar is provided with a squared flat groove. When the pressure regulating cover is given with a standard pressure, the squared flat groove is rotated to control the locking bar to move back and forth. When the lock head is closely combined with the wall face of a pressure regulating disc, the pressure regulating cover can not be rotated without a special flat groove wrench to regulate pressure. The work pressure locking device of a gas regulator is advantageous in that illegal behavior of non-professionals to regulate work pressure of gas at random can be prevented; the occurring of gas accidents can be prevented.
Description
(1), technical field
The utility model relates to a kind of protection of city gas pressure governor, particularly a kind of locking device of gas pressure regulator, governor working pressure.
(2), background technique
In city gas, the pressure governor of each combustion gas usefulness gas point, owing to maintain easily, keep in repair and speedily carry out rescue work, pressure governor can not be locked, and the working pressure of pressure governor is set up, and is that the left rotation and right rotation of pressure regulating cover is very simple; Therefore, the illegal act that layman or user adjust disorderly gaseous-pressure privately often has generation, and gently then civil gas management department is difficult to standard, and greatly then the superpressure air feed makes before the kitchen range flexible pipe gas leakage that comes off, and serious blast accident takes place.
(3), summary of the invention
The purpose of the utility model just provide a kind of simple in structure, be easy to make, the locking device of safe and reliable gas pressure regulator, governor working pressure; It neither changes the pressure governor any structure, the convenience that does not also influence maintenance, repair and speedily carry out rescue work, and just lock pressure regulating cover; The layman does not have special tool; Be to transfer privately the working pressure of pressure governor, and this locking pressure regulating cover can reach general effect, original pressure governor in moving, coming into operation also can be used.
The purpose of the utility model is to realize that through such technological scheme it is in the pressure regulating cover center portion locking bar to be set, and locking bar is connected with the wire distribution of pressure regulation locking closure; Being stuck ball type with tapered end flexibly connects; Locking bar is provided with flat groove four directions, behind the given standard pressure of pressure regulating cover, rotates flat groove four directions control locking bar and moves forward and backward; When tapered end and pressure regulation dish wall fit, when no special-purpose flat groove spanner, can't rotate pressure regulating cover and transfer pressure.
Owing to adopted technique scheme, the utlity model has simple in structure, advantage such as be easy to make, safe and reliable, solved the illegal act that the layman arbitrarily adjusts disorderly gaseous-pressure, avoid the generation of accident.
(4), description of drawings
The description of drawings of the utility model is following:
Figure is the structural representation of the utility model;
Among the figure: 1. pressure regulating cover; 2. pressure regulating cover is outer; 3. pressure regulation groove; 4. locking bar: 5. flat groove four directions; 6. plastics tapered end.
(5), embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
As shown in the figure; The utility model is included in after pressure regulating cover 1 rotates to the working pressure of pressure governor standard through pressure regulation groove 3; Rotation is flat groove four directions 5 on the locking bar, makes locking bar 4 promote plastics tapered ends 6 and fits with pressure regulation dish wall, when no special-purpose flat groove spanner, can't rotate pressure regulating cover 1; Stop the layman and arbitrarily adjust disorderly the combustion gas working pressure, avoid the generation of gas accidents.
Claims (2)
1. the locking device of a gas pressure regulator, governor working pressure is characterized in that: it is by being provided with wire distribution locking bar (4) at pressure regulating cover (1) middle part through the lid center, and locking bar (4) is stuck ball type with tapered end (6) and flexibly connects.
2. the locking device of gas pressure regulator, governor working pressure as claimed in claim 1 is characterized in that: locking bar (4) moves forward and backward locking pressure regulating cover (1) by flat groove four directions (5) Spin Control.
