Abstract
The invention discloses a leak-proof gas meter concentrated gas-distribution converged pipe support shaped like a Chinese character 'fei'. The leak-proof gas meter concentrated gas-distribution converged pipe support shaped like the Chinese character 'fei' comprises a main gas inlet pipe and branch gas inlet bending pipes. One end of the main gas inlet pipe is a connecting end. Connecting threads are arranged at the connecting end and used for being connected with gas pipelines. The other end of the main gas inlet pipe is a sealed end. The branch gas inlet bending pipes are symmetrically arranged on two sides of the main gas inlet pipe. The branch gas inlet bending pipes are located inside the same plane in the perpendicular direction to form the structure shaped like the Chinese character 'fei'. An exposed end of each branch gas inlet bending pipe is provided with connecting threads. In a gas leading branch circuit of each house, threaded connection just exists at two ends of a two-way air valve. Compared with the prior art, the leak-proof gas meter concentrated gas-distribution converged pipe support shaped like the Chinese character 'fei' reduces two possible air leakage positions, not only is convenient for operators to install, but also reduces air leakage points, and improves leak-proof performance of a gas meter concentrated gas-distribution integrated device.
Description
Technical field:
The present invention relates to be used in a kind of combustion gas house lead in system connection gas circuit header frame that each family gas meter is installed in the corridor unit.
Background technique:
Combustion gas is a kind of clear energy sources, and it is easy to use, the vast cities and towns of China have been extensive use of pipeline gas, and in source of the gas house lead in system, source of the gas must concentrate the gas meter at distribution header frame and each family could be to each resident family's air feed by gas meter after sending into each unit of each building building.At present, general gas meter is concentrated distribution header shelf structure as shown in Figure 1, it comprises main suction tude 1, prop up suction tude 2, two vent valves 3, gas meter 4 and tee union 5, main suction tude 1 is big caliber weldless tube, one end and underground supply air line lead to, described main suction tude 1 is spun by main adapter and tee union 5 sealings and forms, an end that props up suction tude 2 is screwed on the tee union 5 hermetically, the other end and two vent valves 3 are tightly connected, gas meter 4 and two vent valves 3 are tightly connected, on main suction tude 1, with serial fashion some above-mentioned linkage units are set, to satisfy the air feed dress table measuring requirement of every household.Concentrate in the distribution header shelf structure at this gas meter, to the way of the gas meter 4 of each household, have five screw-on places from main suction tude 1, tee union 5, a suction tude 2, two vent valves 3, all can produce gas leakage if the installation quality that spins of screw-on place is bad.And installation quality and staff's conscientious degree is closely related, owing to staff's carelessness or part are made reason, is easy to form because being connected the phenomenon that blow-by produces gas leakage in the joint of tee union 5 with main suction tude 1 or a suction tude 2; The not only valuable combustion gas resource of waste, and combustion gas has been polluted the leakage point ambient air because of its characteristics such as inflammable, explosive, poisonous, the proper functioning of citizen, unit and life order around having influenced, and have potential safety hazard.Therefore must install the pipeline frame concentratedly to existing gas meter and improve, stop the gas leakage defective of each tie point.
Summary of the invention:
The purpose of this invention is to provide a kind of non-font anti-leak gas meter and concentrate distribution header frame.
The technological scheme that the present invention takes is:
A kind of non-font anti-leak gas meter is concentrated distribution header frame, comprise main suction tude 1 and an intake elbow, one end of main suction tude is connecting end, connecting end is provided with connecting thread, is used for being connected with fuel gas pipeline, and the other end of main suction tude is sealed end, bilateral symmetry in main suction tude is provided with some intake elbows, all intake elbows are in the same plane in the vertical direction, form " non-" font structure, and the exposed junction of every intake elbow is provided with connecting thread.
Further, the sealed end of main suction tude is fixing seal structure, by the seal welding mode end cover is arranged fixedly in the body endoporus of main suction tude.
Further, the sealed end of main suction tude is the removable seal structure, and the body endoporus of main suction tude and screw thread are connected by thread seal between silently.
Further, be provided with the pipe coupling of protrusion in the bilateral symmetry of main suction tude, be provided with tightening nut at the other end of an intake elbow, an intake elbow is threaded with pipe coupling by tightening nut.
Further, the connecting end of described main suction tude is provided with outer taper pipe thread.
Further, the connecting end of described main suction tude is provided with internal thread.
Further, the connecting thread of described exposed junction is internal thread.
Further, the connecting thread of described exposed junction is outer taper pipe thread.
Because main suction tude is provided with some intake elbows, can satisfy a large amount of gas meter demands like this, exposed junction at every intake elbow is provided with connecting thread, when like this gas meter being installed, operator are as long as be screwed in two vent valves on the intake elbow by the sealing of the connecting thread on the intake elbow, the suction port of gas meter and two vent valves are tightly connected get final product, in each household bleed branch road, only exist at the two ends of two vent valves and be threaded, reduce the place of may losing heart, two places than prior art, both made things convenient for operator's installation, reduced the gas leakage point again, improve gas meter and concentrated the anti-leakage of distribution integrated device, if the sealed end of main suction tude 1 is made as the removable seal structure, then be convenient to get rid of the foreign material such as grit in the distribution header frame.
