The third connect to set up in the gas thread of upper end and be connected with one and prevent tearing open the stopcock head, prevent that the up end of tearing the stopcock head open is equipped with round counter bore, at the global tooth's socket that is the equidistance and arranges that is equipped with of circle counter bore. The third lower part that connects the lower extreme hole be provided with left -handed screw, the spiro union has a column sealing plug in the screw thread, is provided with the recess on the axle on column sealing plug upper portion is global, inlays in the recess and is equipped with sealed rubber ring, is provided with the heavy screw of right -handed thread at the up end of column sealing plug. The utility model discloses an it connects to prevent tearing open reduced tee's third connect go up set up prevent tearing open stopcock head and column sealing plug, must use specialized tool just can open to, can effectively prevent at will in the use or the emergence of dismouting gas pipeline phenomenon without authorization.
Description
Technical field
The utility model relates to a kind of pipe coupling, the particularly special tamper reducing T of a kind of combustion gas for gas pipeline.
Background technique
At present, the reducing T generally used in the civil building gas ductwork of central gas supply is the reducing T that common pipeline is conventional, this reducing T is when piping network installation uses, the small-bore channel interface of its middle joint is generally the shunt tubes interface as registering one's residence, not moving in user up till now interface of opening an account is clog sealing with common pipeline chock plug, be easy to by with the random dismounting of common Wrench, many people ignore safety dismounting and move and connect gas-fired equipment privately, cause surreptitiously gas and gas leakage violating the regulations, cause the generation of combustion gas poisoning, even cause more serious consequence, as fire etc., great hidden danger is caused to people life property safety.Another when professional combustion gas installation personnel opens fuel gas pipeline for user connects, when pipeline is connected with combustion gas in normal operation, the combustion gas in also must first blinding off a line just can operate, and normally uses combustion gas easily to impact like this to opening user.
Model utility content
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and provide one to carry out Curve guide impeller to existing reducing T, in the small-bore channel interface of reducing T, be provided with the tamper chock plug that special tool must be utilized just can to open, can effectively prevent arbitrarily or the special tamper reducing T of a kind of combustion gas of dismounting without authorization.
The technological scheme that the utility model adopts is: a kind of tamper reducing T, comprise joint body, joint body is provided with the first joint of band Internal Pipe Thread, the second joint and the 3rd joint, the endoporus of three joints is interconnected, and it is characterized in that: the internal orifice dimension of the 3rd described joint lower end is less than upper pipes tapped bore; Arrange in the 3rd described upper end of joint pipe thread and be connected with a tamper pipe close head, the upper-end surface of tamper pipe close head is provided with round counterbore, is provided with the teeth groove in equidistant arrangement at circle counterbore side face; The bottom of the 3rd described joint lower end endoporus is provided with left-handed thread, column sealing plug is bolted with in screw thread, the top of the same 3rd joint lower end endoporus in top of column sealing plug is in being slidably matched, the axle side face on column sealing plug top is provided with groove, be embedded with O-ring seal in a groove, the upper-end surface of column sealing plug is provided with heavy screw, and the screw thread in heavy screw is right-handed thread.
Further, the shape of the teeth groove that described round counterbore side face is provided with is square.
Further, the shape of the groove that the axle side face on described column sealing plug top is arranged is square, and quantity is 1 to 2 road.
Compared with prior art, the utility model has the advantage of: owing to being provided with the tamper pipe close head and column sealing plug that special tool must be utilized just can to open in the small-bore channel interface of reducing T, thus, can effectively prevent arbitrarily in using or the generation of dismounting phenomenon without authorization.Meanwhile, professional combustion gas installation personnel connect for user open fuel gas pipeline time, also can when utilize when combustion gas in not blinding off a line special tool convenient open tamper pipe close head and take out that column sealing plug carries out pipeline connect operation.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
Shown in Figure 1, a kind of tamper reducing T of the present utility model, comprises joint body 1, joint body 1 is provided with and is with the first joint 11, second joint 12 of Internal Pipe Thread and the endoporus of the 3rd joint 13, three joints to be interconnected.The first described joint 11 is identical with the interface internal diameter size of the second joint 12, and the interface internal diameter of the 3rd joint 13 is less than the interface internal diameter of the first joint 11 and the second joint 12.The internal orifice dimension of the 3rd described joint 13 lower end is less than upper pipes tapped bore, and the internal orifice dimension of actual product the 3rd joint 13 lower end is less than the spool bore internal diameter of the air valve that threeway is connected with the 3rd joint 13 in use.Arrange in the 3rd described joint 13 upper pipes screw thread and be connected with a tamper pipe close head 2, the upper-end surface of tamper pipe close head 2 is provided with round counterbore 21, and be provided with the teeth groove 22 in equidistant arrangement at circle counterbore 21 side face, the shape of teeth groove is square or other shapes.The bottom of the 3rd described joint 13 lower end endoporus is provided with left-handed thread 31, column sealing plug 3 is bolted with in screw thread, the top of the same 3rd joint 13 lower end endoporus in top of column sealing plug 3 is in being slidably matched, the axle side face on column sealing plug 3 top is provided with groove 32, the shape of groove 32 is square or circular, quantity can be 1 to 2 road, it is 1 road that the shape of the present embodiment further groove 32 is chosen as square, quantity, is embedded with O-ring seal 33 in groove 32.The upper-end surface of column sealing plug 3 is provided with heavy screw 34, and the screw thread in heavy screw 34 is right-handed thread.During use, turn clockwise after utilizing the screw 34 on special tool and column sealing plug 3 to be spirally connected, take out after the lower thread that column sealing plug 3 namely can be made to depart from the 3rd joint 13 lower end endoporus is spirally connected.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and amendment to above-mentioned mode of execution.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection domain of the utility model claim modifications and changes more of the present utility model.
