Background technology
In gas industry or pipeline oil transportation engineering, generally use meter connector, when piping erection, can play the purpose that pipeline connects and seals with meter connector.If any application number is that the Chinese invention patent " gas kitchen pipe joint " of 200610052830.4 (notification number is CN1908495A) discloses a kind of gas kitchen pipe joint, it has the head of accepting that head is provided with hickey, the interior shoulder place of hickey is provided with packing washer, the afterbody of accepting head is bolted with nut, and the afterbody of nut protrudes out and is formed with the ring-type cranse to the center; Also have spacer sleeve, the protruding circle of spacer sleeve is stuck in the cranse of nut and accepts between the afterbody of head, and the afterbody of spacer sleeve then stretches out outside the cranse of nut; The head of the endoporus of spacer sleeve forms interior shoulder, and the tail end face place of accepting head then is provided with cyclic sealing gasket; Pipe nipple or wait that the head that taps into the gas flexible pipe is provided with the radially collar flange of evagination, collar flange then is limited between the interior shoulder of spacer sleeve and the cyclic sealing gasket and with cyclic sealing gasket and forms sealing, and the afterbody that pipe nipple or wait the taps into the gas flexible pipe then endoporus of self-isolation cover stretches out outside spacer sleeve.The pipe adapter of said structure in the pipeline, also has good sealing property and thermal insulation before and after connecting, and has long serviceable life.
But at present, mostly the meter connector of gas industry is to be installed on the gas meter entrance end, only gas meter is imported and exported two lateral lines and play anastomosis, need carry out pressure measurement to pipeline if any reasons such as detections, then must on fuel gas pipeline, stay a pressure tap, so not only increase the pipeline installation cost, and increased unsafe factor.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, direct meter connector of pressure measurement at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: but be somebody's turn to do the pressure gauge joint, include joint, and the loose joint nut that is fixedly connected on described joint one end, it is characterized in that: described joint also offers the side opening of a band packoff on outer surface.
Installation for the ease of pressure instrumentation, described side opening is projected with a protruding neck with threaded hole vertically, described protruding neck has interior shoulder at the openend of threaded hole, described packoff includes O-ring seal and screw, described O-ring seal is arranged on the described interior shoulder, described screw with described O-ring seal is fixed in after threaded hole is threaded described between shoulder and the screw, so, described O-ring seal and screw can play the effect that seals this side opening and then sealing pipeline when the side opening of meter connector does not use.
For preventing that foreign material from falling in the side opening, can adopt various closing devices to realize the sealing of side opening, can be arranged with protective jacket on the described more protruding neck simply, play certain dustproof effect.
In order to guarantee tight connection and the high leakproofness between traveling nut and the joint, described joint one end that is fixedly connected with the loose joint nut has along the cambered outwards collar flange of neck, described collar flange offers the xsect semicircular in shape again on periphery, interior inlay card has the groove of back-up ring, one sealing gasket is enclosed within described joint one end and offsets with the lower surface of described collar flange, described loose joint nut has the ring-type cranse at afterbody, on the back-up ring of the evagination of described ring-type cranse cutting ferrule in being arranged on described groove and described loose joint nut and described joint one end are flexibly connected.So described loose joint nut just is set in joint one end, and free to rotate.
For the ease of the connecting line termination, the described joint other end can also have the external thread that can connect other pipeline.
Compared with prior art, advantage of the present utility model is: on the basis with common meter connector connecting pipeline function, by on joint, offering a side opening with protruding neck, can easily pressure instrumentation be installed on the meter connector by protruding neck, thereby need not on fuel gas pipeline, to leave the pressure that other opening just can be measured pipeline, reduce the pipeline installation cost, improved the security of measuring.Simultaneously, the utility model also designs a packoff that comprises O-ring seal and screw, adopt the closing device of a protective jacket simultaneously as dustproof usefulness, guaranteed the sealing of pipeline under normal conditions, when needs are measured line pressure, take away protective jacket, remove O-ring seal and screw, just can open side opening, install the pressure measurement instrument and get final product gaging pressure; After having surveyed, pull down the pressure measurement instrument, adopt O-ring seal, screw and protective jacket that side opening is blocked again, guarantee common meter connector original function.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Shown in Fig. 1～3, but preferred embodiment for a kind of pressure gauge joint, this meter connector includes joint 1 and is fastened in the loose joint nut 2 of joint one end a, wherein, on joint 1 outer surface, also offer side opening 11, described side opening 11 is projected with one with threaded hole 121 protruding neck 12 vertically, and protruding neck 12 takes on 122 in the openend of threaded hole 121 has
As shown in Figure 2, described side opening also is provided with a packoff that comprises O-ring seal 3 and screw 4 at protruding neck opening part, so that when not using side opening, side opening 11 can be blocked, wherein, described O-ring seal 3 is arranged on the described interior shoulder 122, described screw 4 with described O-ring seal 3 is fixed in after threaded hole 121 is threaded described between shoulder 122 and the screw 4, thus, described O-ring seal and screw can play the effect that seals this side opening and then sealing pipeline when the side opening of meter connector does not use.In addition, for the seal that the prevents protruding neck ash that falls, on protruding neck 12, also be arranged with protective jacket 5 and be used for sealing protruding neck opening.
