Abstract
The utility model discloses a relief valve of putting out a fire, its technical scheme main points are the cover has the spring of arranging in the pressure cap on the lead screw, still be equipped with the one end first conflict ring inconsistent with spring one end on the lead screw, one deck tin has been welded between lead screw and the hand wheel, the utility model aims to provide a but the relief valve of putting out a fire that automatic fire extinguishing and leakproofness are strong.
Description
Technical field
The utility model relates to a kind of valve technology field, and more particularly, it relates to a kind of fire-fighting safety valve.
Background technique
Safety valve is in normally off under open-shut device is subject to External Force Acting, when the pressure medium in equipment or pipeline increases to over specified value, the Special valve of specified value is exceeded by preventing pressure medium in pipeline or equipment to discharge medium outside system, but when in use, all many times artificially enter to close in advance, when breaking out of fire, but because time internal pressure does not possess the high pressure of setting, need artificially to close, have little time sometimes to close, by the seriousness of the solution aggravation accident of valve internal, many times also there is the situation of inner sealing difference.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model be to provide a kind of can self-extinguishing and the strong fire-fighting safety valve of sealing.
For achieving the above object, the utility model provides following technological scheme: a kind of fire-fighting safety valve, comprise valve body, the screw mandrel be placed in valve body, be placed on the outer pressure cap be connected with valve body screw thread of screw mandrel and the handwheel being placed on screw mandrel termination, it is characterized in that: on described screw mandrel, cover has the spring be placed in pressure cap, described screw mandrel is also provided with one end and inconsistent the first conflict ring of spring one end, between described screw mandrel and handwheel, is welded with one deck tin.
The utility model is set to further: the melting temperature being welded with one deck tin between described screw mandrel and handwheel is 65-75 degree.
The utility model is set to further: described screw mandrel is also provided with the second conflict ring, and described second conflict is parallel to each other with the first conflict ring, and between described first conflict ring and the second conflict ring, cover has the first O-ring seals.
The utility model is set to further: be provided with the divider inconsistent with screw mandrel one end in described valve body, described divider comprises spacing block and lower spacing block, described upper spacing block and lower spacing block are provided with breach, and on described screw mandrel, overcoat has the second O-ring seals being stuck in indentation, there.
By adopting technique scheme, by the tin welded between handwheel and screw mandrel, when handwheel rotates time, drive screw mandrel rotates, product is made to be in opening state, in time going wrong, time the serviceability temperature of product exceedes the temperature of tin self, the tin meeting Automatic-falling welded, then coordinate the elastic compression of spring when opening, to the extruding of the first conflict ring, with screw mandrel depressed fast, rapid liquid of closing flowing, thus cut off circulation passage voluntarily, serve and prevent security incident from occurring.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Reference character in figure: 101, valve body; 201, screw mandrel; 202, the first conflict ring; 203, the second conflict ring; 301, pressure cap; 401, handwheel; 501, tin; 601, spring; 701, the first O-ring seals; 702, the second O-ring seals; 801, upper spacing block; 802, lower spacing block; 803, breach.
Embodiment
With reference to Fig. 1, the utility model embodiment is described further.
A kind of fire-fighting safety valve, comprise valve body 101, the screw mandrel 201 be placed in valve body 101, be placed on the outer pressure cap 301 be threaded with valve body 101 of screw mandrel 201 and the handwheel 401 being placed on screw mandrel 201 termination, it is characterized in that: on described screw mandrel 201, cover has the spring 601 be placed in pressure cap 301, described screw mandrel 201 is also provided with inconsistent the first conflict ring 202 in one end and spring 601 one end, between described screw mandrel 201 and handwheel 401, is welded with one deck tin 501.
By adopting technique scheme, by the tin 501 of weldering between handwheel 401 and screw mandrel 201, when handwheel 401 rotates time, screw mandrel 201 is driven to rotate, product is made to be in opening state, in time going wrong, time the serviceability temperature of product exceedes the temperature of tin 501 self, the tin 501 meeting Automatic-falling welded, then coordinate the elastic compression of spring 601 when opening, to the extruding of the first conflict ring 202, with screw mandrel 201 depressed fast, rapid liquid of closing flowing, thus cut off circulation passage voluntarily, serve and prevent security incident from occurring.
The utility model is set to further: the melting temperature being welded with one deck tin 501 between described screw mandrel 201 and handwheel 401 is 65-75 degree.
By adopting technique scheme, the melting temperature being welded with one deck tin 501 between screw mandrel 201 and handwheel 401 is 65-75 degree, can carry out good prevention when low temperature to accident, ensures the Security used.
The utility model is set to further: described screw mandrel 201 is also provided with the second conflict ring 203, and described second conflict is parallel to each other with the first conflict ring 202, and between described first conflict ring 202 and the second conflict ring 203, cover has the first O-ring seals 701.
By adopting technique scheme, screw mandrel 201 is also provided with the second conflict ring 203, described second conflict is parallel to each other with the first conflict ring 202, between described first conflict ring 202 and the second conflict ring 203, cover has the first O-ring seals 701, by the setting of the first O-ring seals 701, utilize its elastic packing, make screw mandrel 201 in the sealing when valve body 101 inside, avoid occurring internal leakage, impact fire extinguishing.
The utility model is set to further: be provided with the divider inconsistent with screw mandrel 201 one end in described valve body 101, described divider comprises spacing block 801 and lower spacing block 802, described upper spacing block 801 and lower spacing block 802 are provided with breach 803, and on described screw mandrel 201, overcoat has the second O-ring seals 702 being stuck in breach 803 place.
By the setting of breach 803 and coordinating of the second O-ring seals 702, the first O-ring seals 701 is coordinated to carry out twice sealing again, thus ensure the integral sealing after closing, after adding whole installation, the second O-ring seals 702 can block with in breach 803, by the total amount of screw mandrel 201, extrude, thus ensure overall sealing, avoid leaked liquid, thus avoid accident further to magnify.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, those skilled in the art carries out common change and replaces should being included in protection domain of the present utility model within the scope of technical solutions of the utility model.
