Description
Technical field
The utility model relates to the design field of valve, particularly relates to a kind of liquefied chlorine loading bellows cut-off valve.
Background technique
Liquid chlorine is yellow-green liquid, and 15 DEG C time, proportion is 1.4256, at standard conditions, boiling point-34.6 DEG C, molten point-103 DEG C, solidify when-101.5 DEG C, namely be gasificated into gas at ambient pressure, suck people's physical efficiency seriously poisoning, belong to major hazard source, there are severe irritation effect and corrosivity, occur when mixing with other inflammable gas in the sunlight to burn and explode, chlorine is very active element, can react with most elements (or compound).
Liquid chlorine cylinder is filling or liquefied chlorine cistern car is filling, and filling pressure is large, and liquid chlorine corrosivity is strong, and cut-off valve switch is frequent.Existing cut-off valve is mostly cutting ball valve, and leak point is many, and ball valve is not high pressure resistant, often there will be leakage phenomenon, and working life is short, and especially hypertoxic medium--chlorine gas leakage, can form life risk to site operation personnel.
How to found a kind of safe, without revealing, the liquefied chlorine loading cut-off valve of high pressure resistant, long service life, to liquefied chlorine loading safety in production, there is very important positive role.
Model utility content
The purpose of this utility model to provide a kind of liquefied chlorine loading bellows cut-off valve, makes its safety, without leakage, high pressure resistant, long service life.
For solving the problem, the utility model provides a kind of liquefied chlorine loading bellows cut-off valve, comprise valve body, center in valve body is provided with valve seat, valve seat is provided with flap, above valve body, valve gap is installed, valve gap is fixed on valve body by pad and nut, flap is provided with valve rod, bellows-sheathed is contained on valve rod, stuffing box is provided with above valve gap, the cavity coincide with the lower end of stuffing box is provided with in valve gap, stuffing box and its cavity boxing coincide are tightly connected, place filler in stuffing box to be compressed by Gland, valve rod above Gland is provided with connector, connector is fixedly connected with by support with diaphragm cylinder.
Valve gap lower end is provided with sealing gasket one, is welded with guide holder below valve gap at valve rod upper sealing ring, is provided with sealing gasket two above guide holder, when valve is opened completely, sealing gasket one and sealing gasket two to, form back seal.
After adopting such design, the utility model at least has the following advantages:
There are 5 resealings, safe and reliable.
Described stuffing box and its cavity boxing coincide are tightly connected, and without leak point, this is first security seal.
Bellows is double-wall corrugated pipe, and reveal one deck bellows and also have one deck bellows in protection, this is second security seal.
Place filler in stuffing box and compressed by Gland, two layers of bellows all break, and liquid chlorine enters stem internal through bellows, and valve rod top also has filler to protect, and this is the 3rd road security seal.
Valve gap and valve body tongue-and-groove sealing configuration, fixed by nut, compression resistance can reach more than 25 kilograms, even if when pipeline pressure fluctuates, also can ensure valve body and valve gap reliable sealing, and this is the 4th road security seal.
Below described valve gap, on valve rod, seal weld is connected to guide holder; valve rod between stuffing box and guide holder has placed bellows; the upper end of bellows and stuffing box seal welding, the lower end of bellows and guide holder seal welding, the lower end of valve gap is provided with sealing gasket; guide holder is provided with sealing gasket; when valve is opened completely, two sealing gaskets to composition back seal, stop stream of liquid chlorine to bellows; at utmost protect bellows, this is the 5th road security seal.
Above-mentioned five seal structures further increase the safety class of valve, achieve zero leakage, are highly suitable for liquefied chlorine loading occasion.
Accompanying drawing explanation
Above-mentioned is only the general introduction of technical solutions of the utility model, and in order to better understand technological means of the present utility model, below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of liquefied chlorine loading bellows of the utility model cut-off valve.
Wherein, 1 is valve body, and 2 is valve seat, and 3 is flap, and 4 is pad, and 5 is nut, 6 is valve gap, and 7 is bellows, and 8 is valve rod, and 9 is filler, and 10 is Gland, and 11 is connector, 12 is diaphragm cylinder, and 13 is guide holder, and 14 is stuffing box, and 15 is sealing gasket one, and 16 is sealing gasket two.
Embodiment
