Description
Technical field:
The utility model relates to a kind of pipe joint with three openings, is specifically that a kind of special-purpose tamper of combustion gas being arranged on gas pipeline prevents eating gas threeway.
Background technique:
The structure of threeway is very simple, generally a threeway body, consists of, and threeway body is provided with three openings, and three of this structure is installed in the intersection of three pipelines conventionally, is used for changing the direction of liquid or gas.When threeway is dispatched from the factory, in three openings on threeway body, conventionally having an opening is given and to block by conventional plug, the object of doing is like this to facilitate user's needs according to oneself after purchase to select whether this plug to be backed out to connect the 3rd pipeline, but for the company of supply combustion gas, for preventing that other people from arbitrarily backing out plug and illegally usurping combustion gas, this plugging structure of conventional plug is certainly not all right, for this reason, some manufacturers are specially for the said firm has developed following plugging structure: comprise tamper plate, gag and sealing gasket, on the periphery wall of tamper plate and gag, be equipped with outside thread, tamper plate middle part has the polygonal through hole inserting for special spanner, gag top surface is provided with the polygonal boss blocking for special spanner, sealing gasket is positioned on the step that open lumen perisporium is provided with, gag is threaded in open lumen and its bottom is pressed on sealing gasket, tamper plate is positioned at gag top and is threaded in opening, as shown in the above, tamper plate and gag must be used special spanner just can back out, although having played, this prevents that other people from illegally usurping the object of combustion gas, but, when turning tamper plate and gag, administrative staff need the combustion gas of carrying in temporary close pipeline, otherwise after backing out tamper plate and gag, a large amount of combustion gas meetings outwards spray from this opening.
Model utility content:
The technical problems to be solved in the utility model is, provides a kind of special-purpose tamper of combustion gas that can operation under pressure anti-ly to eat gas threeway.
Technical solution of the present utility model is, provide a kind of special-purpose tamper of combustion gas with following structure to prevent eating gas threeway: to comprise threeway body, tamper plate, gag and sealing gasket, threeway body is provided with three openings, on the periphery wall of tamper plate and gag, be equipped with outside thread, tamper plate middle part has the polygonal through hole inserting for special spanner, gag top surface is provided with the polygonal boss blocking for special spanner, sealing gasket is positioned on the step that one of them open lumen perisporium is provided with, gag is threaded in open lumen, tamper plate is positioned at gag top and is threaded in opening, wherein, also comprise trim ring and sealing mat, sealing mat is rounded and adopt aluminium material to make, trim ring and sealing mat are all between gag and sealing gasket, trim ring by self periphery wall be threaded on open lumen wall and its bottom is pressed on sealing mat, sealing mat is pressed on sealing gasket.
The special-purpose tamper of combustion gas described in the utility model is anti-eats gas threeway, wherein, on sealing mat top surface, along self central axis, is evenly distributed in a plurality of v-depressions.
The special-purpose tamper of combustion gas described in the utility model is anti-eats gas threeway, wherein, has the groove inserting for straight screwdriver on trim ring top surface.
Adopt after above structure, compared with prior art, the special-purpose tamper of the utility model combustion gas is anti-eats gas threeway and has the following advantages: with prior art threeway when backing out tamper plate and gag, need the combustion gas difference of carrying in administrative staff's temporary close pipeline, the special-purpose tamper of the utility model combustion gas prevents that eat gas threeway is provided with trim ring and sealing mat between gag and sealing gasket, and trim ring bottom is pressed on sealing mat, like this, at trim ring, press under the seal action of sealing mat, administrative staff are without closing the combustion gas of carrying in pipeline again, can directly be with gas to carry out operation, it should be noted that, when administrative staff dismantle after tamper plate and gag, can directly ball valve be arranged on this opening, rotate ball valve handle to open ball valve, with an elongated iron staff, through ball valve inner chamber, pierce through sealing mat subsequently, after piercing through, transfer to fast iron staff and close ball valve, time short, operation rapidly, air leakage is considerably less.
The setting of v-depression is convenient to administrative staff and is used iron staff that sealing mat is pierced through.
