Abstract
The utility model relates to a chlorine emergency cut-off valve, which belongs to a field of cut-off valve device with a closing element and comprises a valve body, wherein, a gas-regulating device is arranged on the valve body; the gas-regulating device is connected with a valve stem on the valve body; the technical proposal is mainly characterized in that: 1) a valve body chassis communicated with the gas-regulating device on the valve body is a squire structure, and an independent secondary packing gland is arranged on an upper end of the valve body chassis; 2) the valve stem is a totally caulking two-section structure, and a polygon caulking groove and a location head mutually matched are processed at two connection ends; 3) secondary packing is sleeved on the valve stem at the lower end of the secondary packing gland. The chlorine emergency cut-off valve has the advantages of a simple and compact structure, online maintenance and improvement of sealing.
Description
Technical field
The utility model belongs to the cut-off valve device field that has closure member, specifically is a kind of chlorine Emergeny Cutoff Valves.
Background technique
Chlorine is one of main raw material gas of each chemical industry production or use; and the chlorine product of chemical industry production or use has highly corrosive; need to press conveying by the continuous band of pipeline; in the gas delivery process; because pressure is bigger; therefore the multigroup safety valve just is installed on pipeline as required; so that in the pressure over range; or conveying circuit the opening fast of safety when breaking down; close; guarantee the normal operation that enterprise produces; the multiple repid cut-off valve that chlorine is carried that is exclusively used in is arranged in the market; but existing various valve is single packing seal; valve rod is an integral structure; valve body directly connects with cutting control device; like this along with the operation of equipment; filler on the valve body is subjected to factor affecting such as aging or pressurized; leakage phenomenon appears easily; need in this case to shut down; and need successively cutting control device and valve rod to be unloaded just and can overhaul; bring great adverse effect for normal production of enterprise, therefore just press for a kind of repid cut-off valve that can onlinely safeguard, make this valve promptly can have the characteristics of prior art; can realize on-line maintenance again, sealing also obtains bigger raising.
The model utility content
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, compact, can realize on-line maintenance, and sealing also obtains the chlorine Emergeny Cutoff Valves of bigger raising.
For achieving the above object, the utility model is achieved through the following technical solutions:
Be a kind of chlorine Emergeny Cutoff Valves, comprise the valve body that is provided with pneumatic regulation unit, the valve rod on pneumatic regulation unit and the valve body links, and the present technique main points are
1) valve block that links with pneumatic regulation unit on the valve body is a square structure, and the valve block upper end is provided with separate with it secondary Gland;
2) valve rod is that mutual setting-in is the two-part structure of one, and two joining ends are processed with the polygonal caulking groove and the positioning head of mutual coupling respectively;
3) suit secondary filler on the valve rod of secondary Gland lower end.
Above-mentioned secondary filler is the monomer by ring structure, and stack is enumerated and formed successively, and secondary filler monomer cross-sectional configuration is that a wherein end of upper end or lower end has projection, and the other end has the groove with this projection coupling.
After the utility model adopts said structure, compared with prior art, have simple in structurely, compact, can realize on-line maintenance, sealing also obtains the advantage of bigger raising.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1: the utility model example structure schematic representation.
Fig. 2: gland mounting structure schematic representation.
Fig. 3: valve rod joining end cross-sectional configuration schematic representation.
Fig. 4: secondary filler cross-sectional configuration schematic representation.
Embodiment
As shown in Figure 1, this chlorine Emergeny Cutoff Valves comprises the valve body 7 that is provided with pneumatic regulation unit 1, and the valve rod 2 on pneumatic regulation unit 1 and the valve body 7 links, and the present technique main points are
1) as shown in Figure 2, the valve block 5 that links with pneumatic regulation unit 1 on the valve body 7 is square structure, and valve block 5 upper ends are provided with separate with it secondary Gland 4;
2) valve rod 2 is the two-part structure of one for mutual setting-in, and two joining ends are processed with the polygonal caulking groove and the positioning head of mutual coupling respectively, as shown in Figure 3;
3) suit secondary filler 6 on the valve rod 2 of secondary Gland 4 lower ends.
Above-mentioned secondary filler 6 is the monomer by ring structure as shown in Figure 4, and stack is enumerated and formed successively, and secondary filler monomer cross-sectional configuration is that a wherein end of upper end or lower end has projection 8, and the other end has the groove 9 with this projection coupling.
Installation of the present utility model and operate same as the prior art.When gas leakage occurring in the valve body 7, only need adjust secondary Gland 4, secondary filler 6 is compressed again, get final product the leakage of control gaseous.When needs are repaired or are changed the secondary filler, also only need open secondary Gland 4, and will move on valve rod 7 epimeres, can separate with valve rod 7 hypomeres, secondary filler 6 is taken out change easily.
After the utility model adopts said structure, compared with prior art, have simple in structurely, compact, can realize online dimension Protect, sealing also obtains the advantage of bigger raising.
Claims (2)
