Abstract
The utility model discloses a valve, in particular to a butterfly valve in a hot-dirty gas transmission system for preventing blocking between a valve body and with a valve plate under horizontal condition, which comprises an actuating member (1), the valve body (2), the valve plate (3), a rotating shaft (4) and a blocking port (5). The utility model is characterized in that a circulation port and a dust hopper (6) connected with the circumferential wall of the circulation port to a whole are arranged at the wall of the valve body (2); at least a through hole is arranged at the lateral wall of the dust hopper (6); a steam pipe (9) with an open and closes valve is connected outside of each through hole; a valve (10) is connected with an outlet of the dust hopper (6) through a flange (11). The valve plate is effectively prevented from sticking on the valve body, and the gap between the valve body and the valve plate caused by an oil block with dust is also prevented. The utility model has the advantages of flexible opening and closing, tight closing and good sealing performance.
Description
Affiliated technical field:
The utility model relates to a kind of valve used in the hot dirty gas transporting system, says so more specifically a kind ofly can prevent the butterfly valve that valve body and valve plate block under level conditions.
Background technique:
For guaranteeing the safe operation of coal gas system, national regulation requires to carry the person in charge to need repid cut-off valve is installed on the net at coal gas, can cut off the coal gas source rapidly in case break down, and avoids expanding of accident.Present valve mechanism is made up of actuator, valve body, valve plate, rotating shaft and seam etc., this valve is using less than after 3 months, when needs fast shut-off hot dirty gas, two kinds of possible situations once can appear: the one,, slit between valve body and the valve plate is very big, can't reliably close, the expansion that causes the accident need make gas producer quit work; The 2nd,, when needs are opened,,, can not reach purpose of opening even if make the rotating shaft torsional deformation sometimes because of valve body and valve plate block and can't open, not only do not have protective action, need on the contrary to stop production and repair, had a strong impact on normally carrying out of producing.The reason that causes valve plate and valve body to block is that hot dirty gas is thorough inadequately in purification process, the suspended particulate that contains in the coal gas, tar fog etc. are deposited between seam and the valve body gradually, time one is long, it is fast to be frozen into dust-laden oil, cause to have big gap between valve and the valve plate, do not reach the purpose of fast and reliable closure, safety cut-off source of the gas.After hot dirty gas piped gas temperature lowered, the dust-laden oil clot that has solidified between seam and the valve body became firm unusually, and valve plate is stuck in this position, does not open Guan Bushang.
Summary of the invention:
The technical problems to be solved in the utility model is, provides a kind of and can prevent effectively that valve plate from blocking, and has quick opening and closing function, and closes tight safe butterfly valve.
For solving the technological scheme that above technical problem takes be, this butterfly valve, by actuator 1, valve body 2, valve plate 3, rotating shaft 4, seam 5 is formed, and is characterized in, the ash dropping hopper 6 that on the wall of valve body 1, is provided with a communication port 7 and is connected as a single entity with this communication port perisporium, at least be provided with a through hole 8 on the sidewall of ash dropping hopper 6, the steam tube 9 of the outside of each through hole and a band open and close valve joins, and is provided with valve 10 in the outlet of ash dropping hopper 6.
Through hole 8 on described ash dropping hopper 6 sidewalls is two, lays respectively on 6 two relative sidewalls of ash dropping hopper.
Described valve 10 is connected through the outlet of flange 11 with ash dropping hopper 6.
Because the utility model is at the ash dropping hopper 6 that is provided with a communication port 7 and is connected as a single entity with this communication port perisporium on the wall of valve body 1, on the sidewall of ash dropping hopper 6, be provided with a through hole 8 at least, the steam tube 9 of the outside of each through hole and a band open and close valve joins, and is provided with valve 10 in the outlet of ash dropping hopper 6.Make it compared with prior art, add steam and can enter valve body by the through hole 8 on steam tube 9 and the ash dropping hopper sidewall, the dust-laden oil clot that is deposited on the valve body is melted, and enter ash dropping hopper 6 along communication port, and flow out by valve 10 again, so both effectively prevented the bonding phenomenon of valve plate and valve body, prevented between valve body and the valve plate slit that the existence because of the dust-laden oil clot causes again, it is flexible to make this valve have an open and close, close tight, gastight advantage.Can play due safety protection effect, prevent the generation of fault and the stopping production phenomenon that causes because of maintenance again, guarantee safe ordinary production.
Description of drawings:
An embodiment's of Fig. 1-the utility model structural representation
The A-A sectional view of Fig. 2-Fig. 1
Embodiment:
Provide embodiment of the present utility model below in conjunction with accompanying drawing, be used for further specifying technical solution.
Embodiment: with reference to figure 1, Fig. 2.Find out that by these two figure butterfly valve is by actuator 1, valve body 2, valve plate 3, rotating shaft 4, seam 5, ash dropping hopper 6, steam tube 9, valve 10 and flange 11 are formed.Ash dropping hopper 6 is plaque shape funnels, and from Fig. 1, its section configuration is the fan-shaped of nearly 90 ° of angles, with valve body 1 be integral structure.Through hole 8 on ash dropping hopper 6 sidewalls is two, lays respectively on 6 two relative sidewalls of ash dropping hopper.The steam tube 9 of two band open and close valves communicates with two through holes 8 respectively.The outlet port of ash dropping hopper 6 is connected with valve 10 by flange 11.By steam tube 9 and ash dropping hopper 6, can in time collect the tar and the granule foreign of valve body lower end, by open valve 10 it is discharged, thereby effectively prevent the generation of butterfly valve stuck phenomenon.
In like manner, the technical solution according to the utility model provides can also provide other embodiment.
Claims (3)
1, a kind of butterfly valve, it is by actuator (1), valve body (2), valve plate (3), rotating shaft (4), seam (5) is formed, it is characterized in that, on the wall of valve body (1), be provided with a communication port (7) and with the ash dropping hopper (6) that this communication port perisporium is connected as a single entity, on the sidewall of ash dropping hopper (6), be provided with a through hole (8) at least, the steam tube (9) of the outside of each through hole and a band open and close valve joins, and is provided with valve (10) in the outlet of ash dropping hopper (6).
