Description
Technical field
The utility model relates to a kind of valve, specifically a kind of non-refillable steel welded cylinder valve with rupture disk.
Background technique
Non-refillable steel welded cylinder valve is widely used in the industries such as chemical industry, medical treatment, machinery, environmental protection, food, is also deposited at present
In following technical problem:
Non-refillable steel welded cylinder need to equip rupture disk (i.e. safe releasing device), and existing valve does not have rupture disk, because
In addition this can only weld rupture disk on steel cylinder；The manufacturing process that rupture disk is welded on steel cylinder is complicated, and manufacture difficulty is big and makes
Make at high cost, and rupture disk passes through thermal cycle after welding, and the explosion value that will lead to rupture disk changes, thus
Influence the normal use of rupture disk.
Utility model content
The purpose of the utility model is to overcome the deficiency in above-mentioned background technique, a kind of non-duplicate with rupture disk is provided and is filled
Steel loading bottle valve, the cylinder valve should have the characteristics that structure is simple, easy for installation, good reliability.
The technical solution of the utility model is:
A kind of non-refillable steel welded cylinder valve with rupture disk, including valve body and the valve rod group being mounted in valve body
Part；The valve body is equipped with the gas nozzle of inner cavity above connection valve seat；It is characterized by: being additionally provided on the valve body under connection valve seat
Rupture disk is pressed on the outlet port of release gas nozzle by the release gas nozzle of square inner cavity, swivel nut；The swivel nut is by being threadedly engaged peace
On release gas nozzle, swivel nut is equipped with the flanging for pushing down rupture disk edge.
The valve rod assembly include protrude into body cavity and can vertical motion valve rod, setting stem bottom and and valve
The spool of seat cooperation, the spring and bolt being arranged between valve rod and spool.
Planar pad and protective case are installed on the gas nozzle.
The beneficial effects of the utility model are:
The sealing structure of the utility model is safe and reliable, convenient to use, avoids quick-fried using welding on steel cylinder in the past
The labyrinth of fragmentation, greatly reduces manufacturing cost, improves reliability, also reduces the leakage point on steel cylinder.
Detailed description of the invention
Fig. 1 is the schematic view of the front view of the utility model.
Fig. 2 is the schematic view of the front view of the prior art.
Specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model be not limited to
Lower embodiment.
As shown in Figure 1, a kind of non-refillable steel welded cylinder valve with rupture disk, including valve body 1 and it is mounted on valve body
In valve rod assembly.The inner cavity extended vertically is equipped in the valve body, the middle part of inner cavity is valve seat 13, the company of being equipped with outside valve body
The gas nozzle 11 and release gas nozzle 12 of logical inner cavity, gas nozzle are located at the top of valve seat, and release gas nozzle is located at the lower section of valve seat.The gas nozzle
Upper setting planar pad 7 and protective case 8, planar pad block the outlet of gas nozzle, and protective case wraps gas nozzle and planar pad.
Rupture disk 3 and swivel nut 2 are set on the release gas nozzle.The swivel nut is mounted on release gas nozzle by being threadedly engaged
On, one end of swivel nut is formed with annular flanging 21.The rupture disk is arranged between the outlet port and swivel nut of release gas nozzle, is used for
The outlet of release gas nozzle is blocked, the flanging for screwing on swivel nut rear thread sleeve tightly suppresses the surrounding edge of rupture disk, to ensure that explosion
The sealing effect of piece.The tabletting center is the hollow area with a certain size, guarantees release gas nozzle row when rupture disk rupture
High-pressure medium out can be released outward by the position.
The valve rod assembly includes valve rod 14, spool 4, safety clip 9, spring 5, bolt 6.The valve rod protrudes into from top to bottom
In body cavity, valve rod and body cavity are by being threadedly engaged realization vertical lifting.The spool is arranged in stem bottom, spring
It is arranged between valve rod and spool with bolt, for bolt for connecting valve rod and spool, spool can be pressed on valve by spring force
On seat.The top (outside valve body) of valve rod is arranged in the safety clip, the O-ring 15 of setting and valve body cooperation on valve rod, on spool
O-ring 15 with valve seat cooperation is set.
In the utility model, rupture disk is fixed by swivel nut, due to not by soldering, the explosion of rupture disk
There is no variations for value, this ensures that rupture disk ruptures to play pressure release effect, guarantee when reaching scheduled pressure value
The safety of personnel and equipment.
