Description
Technical field
The utility model relates to combustion gas or water engineering parts, the bypass of especially a kind of band gas or the connection of water operation arm.
Technical background
As everyone knows, feedwater or give in the gas engineering usually by be connected numerous arms on the main with water or pneumatic transmission toward huge numbers of families.At present, this class main or arm have all adopted polyethylene pipe, are connected between main and arm to adopt the tricky branch end of threeway or adopt electric smelting saddle type bypass to draw arm, and the former installs in the pipeline construction process; The latter both can install in work progress, also can install after the main pipe construction is finished.Both common ground all be needs cut off the water for a long time or the state of stopping the supple of gas or steam under construction and installation.This cutting off the water or the adapter form of construction work of stopping the supple of gas or steam can cause an arm to connect the situation that main is stopped the supple of gas or steam or cut off the water completely.Make troubles for other arm user.For overcoming above-mentioned defective, had on the market and under ventilation or water state, carried out the bypass that arm connects operation, its structure as shown in Figure 1, this bypass tube of PE pipe that is applicable to is by PE saddle type bypass valve body 3, the punching cutter 4 that is installed on PE saddle type bypass valve body 3 internal thread segment is formed with the heater band 6 on the saddle type cambered surface that is arranged on PE saddle type bypass valve body, the heater band 6 that utilization is arranged on the cambered surface can be welding in PE saddle type bypass valve body on the PE pipe in advance, then by the punching cutter 4 in the spanner turn PE saddle type bypass valve body 3, utilization punching cutter wall 4 cooperates with internal thread segment, impel it to move downward, carry out cutting and boring by 4 pairs of PE pipes of punching cutter.After finishing punch-cuts, counterrotating punching cutter makes it retreat to the arm top, then bypass end cap 2 is covered, and can finish the connection operation of PE pipe racks water operation bypass arm.The bypass of this structure has realized greatly facilitating the user not cutting off the water or the connection of the state lower branch line bypass of stopping the supple of gas or steam.It is unreasonable that yet existing this class bypass sealing configuration and heater band are provided with, and has following defective: one, the punching cutter of steel and cooperating of polymer internal thread, the phenomenon that the cutter that easy appearance causes because of sliding tooth during punch operation is fractureed.Although cooperating with drawing-off mouth, two cylindric punching cutter 4 newel post's heads are provided with seal ring between cylinder, be provided with seal ring between the mouth of pipe of PE saddle type bypass valve body punching cutter end and closed end cap, rely on the own elasticity of seal ring can realize its sealing function, but along with the flexible reduction of seal ring, its sealing function will be along with weakening.Therefore, there is leakage defect in bypass mostly.Three, the heater band that is arranged on the saddle type cambered surface of PE saddle type bypass valve body is a single face wiring heating liner, and it occurs short circuit easily, can occur slightly accidentally during welding rosin joint and or drawback such as failure welding, thereby influence the quality of product.
Summary of the invention
The purpose of this utility model is the deficiency that exists at above-mentioned bypass, and the bypass of a kind of band gas or the connection of water operation arm is provided.
The bypass of the utility model band gas or the connection of water operation arm comprises: PE saddle type bypass valve body, the cutter and be arranged on heater band on the saddle type cambered surface of PE saddle type bypass valve body of punching is characterized in that:
Be provided with the metal internal thread cover in a, the PE saddle type bypass valve body, the punching cutter is installed in the metal internal thread cover;
Be provided with seal ring between b, punching shoulder portion and PE saddle type bypass valve body necking end interior edge face;
C, described heater band are that two sides wiring saddle type adds heating pad.
Described two sides wiring saddle type adds heating pad and is provided with the resistance alloy that clockwise spiral fluted saddle type liner and thermocompression bonded be connected in its tow sides spiral chute by tow sides and constitutes, resistance alloy one end in the tow sides spiral chute is by the series connection of the string hole on the saddle type liner, and the end in addition of resistance alloy is connected to copper electrode respectively in the tow sides spiral chute.
The bypass design science of the utility model band gas or the connection of water operation arm, rational in infrastructure.Compare with existing like product and to have the following advantages: 1, cooperating of the outside thread of punching cutter and metal internal thread cover, can guarantee that the intensity of product is enough, occur the phenomenon that is fractureed because of cutter that the cunning tooth causes when having avoided punch operation.2, the lifting that cooperates that utilizes punching cutter wall and the interior metal internal thread of bypass tube to overlap, can regulate is arranged on being stressed of seal ring between its counterface, seal ring is realized its sealing function under pressured state, the seal ring that increases and original two place's seal rings form the multiple tracks compound seal, have improved the sealing of bypass greatly.3, utilize characteristics on the two sides wiring saddle type heating bedding construction, the short circuit phenomenon when overcoming bypass and being responsible for the melting welding operation is guaranteed the fusion welding quality between bypass and the person in charge.
The concrete structure of the bypass of the utility model band gas or the connection of water operation arm is provided in detail by the following drawings and embodiment.
