Description
Technical field
The utility model belongs to valve field more particularly to a kind of shut-off valve.
Background technique
In petroleum refining process, hydrogenation plant is the important equipment for improving petroleum product-quality, one on adding hydrogen pipeline
As using shut-off valve come the circulation and truncation of control piper medium.Due to adding hydrogen medium to have, inflammable and explosive, corrosivity is strong, medium
Leakage be easy to cause safety accidents, the existing shut-off valves such as burning, explosion and corrosion equipment to grind in valve rod and valve cover chamber filler
Damage is when leaking, cannot timely automated prompt leak, safety in utilization is poor.
Summary of the invention
The utility model in view of the drawbacks of the prior art, provide it is a kind of can be automatically reminded to leak, the cut-off having a safety feature
Valve.
The technical solution of the utility model is：Including valve body, valve rod, bracket, handwheel, one end of valve rod passes through valve stem nut
It is fixedly connected with the hand wheel, filler is equipped between valve body and valve rod, gland compresses filler, valve outlet channel by stuffing-box
The structure at an acute angle between valve rod center line is connected with nipple on stuffing-box, and the mainly nipple other end is filled equipped with alarm
It sets, the alarm device is by lamp cap, liquid mercury ball, movable plate, piston piece and support bar group at the liquid mercury ball is located at lamp chamber
It is interior, it can scroll left and right, the two contact conducting wire that do not touch connection lamp caps are equipped in lamp chamber, are fixed with activity below lamp chamber
Plate, movable plate are fixedly connected by bolt with the piston piece in nipple, below the piston piece in thickness diameter and nipple
Wall diameter is identical, and piston piece weight is matched with safe pressure value, and movable plate midpoint is equipped with pin shaft, passes through pin shaft movable plate and branch
Strut is flexibly connected, and is fixed in the supporting table being shorted in pipe outer wall below support rod, is shorted inside pipe wall and is equipped with a circle support ring,
Its diameter is slightly less than short circuit tube inner diameter.
The utility model has the advantages that working as packing leaking by the design of alarm device, gas pressure intensity can be by piston piece top
It rises, so that the movable plate right side be made to stick up, liquid mercury ball rolls to the left side, is connected to two piece-root grafting point conducting wires, and connecting circuit lights warning light,
Reach the function of being automatically reminded to leakage, safety greatly improves.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
In figure, 1 valve body, 2 valve rods, 3 fillers, 4 nipples, 5 alarm devices, 6 brackets, 7 plane bearings, 8 valve stem nuts, 9

Fig. 2 is alarm device amplification assumption diagram.
In figure, 13 support rings, 14 supporting tables, 51 piston pieces, 52 movable plates, 53 lamp chambers, 54 liquid mercury balls, 55 contacts are led
Line, 56 lamp caps, 57 pin shafts, 58 support rods.
Specific embodiment
According to Figure of description, the utility model is described further.
Shut-off valve as shown in Figure 1, including valve body 1, valve rod 2, bracket 6, handwheel 9, one end of valve rod 2 pass through valve stem nut
8 are fixedly connected with handwheel 9, and filler 3 is equipped between valve body 1 and valve rod 2, and gland 10 compresses filler 3, valve by stuffing-box 12
Structure at an acute angle between 2 center line of 1 exit passageway of body and valve rod is connected with nipple 4,4 other end of nipple on stuffing-box 12
Equipped with alarm device 5；The alarm device 5 as shown in Figure 2 is by lamp cap 56, liquid mercury ball 54, movable plate 52, piston piece 51 and branch
Strut 58 forms, and the liquid mercury ball 54 is located in lamp chamber 53, can scroll left and right, and does not touch in lamp chamber 53 equipped with two
Contact conducting wire 55 connects lamp cap 56 connects two piece-root grafting point conducting wires 55, to be connected to electricity when liquid mercury ball 54 is rolled into right end
The bright warning light of waypoint, movable plate 52 is fixed with below lamp chamber 53, and movable plate 52 is solid by the piston piece 51 in bolt and nipple 4
Fixed connection, 51 lower section thickness diameter of piston piece is identical as the inner diameter of nipple 4,51 weight of piston piece and safe pressure value
Piston piece 51 can be jacked up after leakage is beyond safe pressure value, 53 right side of lamp chamber is stuck up by matching, so that liquid mercury ball 54 be made to roll
To 55 connection circuit of contact conducting wire in 53 left side of lamp chamber, 52 midpoint of movable plate is equipped with pin shaft 57, passes through 57 movable plate 52 of pin shaft
It is flexibly connected, is fixed below support rod 58 in the supporting table 14 of 4 outer wall of nipple with support rod 58,4 inner wall of nipple is equipped with
One circle support ring 13, diameter are slightly less than 4 inner diameter of nipple, and 4 exit of nipple is similarly designed to be slightly less than piston piece
The size of 51 maximum gauges, to limit the up and down range of piston piece 51.
The utility model is described in detail above by embodiment, but the content is only the utility model
Preferred embodiment should not be considered as limiting the scope of the present invention.It is all according to the present utility model application
Variation and improvement etc., should still belong within the patent covering scope of the utility model made by range.
