Abstract
The utility model discloses a flat insertion type gas pipe joint which comprises a pipe-shaped joint body, wherein a raised positioning end is arranged in the middle of the joint body; a gas inlet pipe joint is arranged on one side of the positioning end, and a gas outlet pipe joint is arranged at the other end of the positioning end; three or more ring-shaped grooves are formed in the circumference of the pipe wall of the gas inlet pipe joint, and included angles of 45 degrees are formed in two ends of each ring-shaped groove; a first sealing ring and a second sealing ring which are parallel in front and at back are arranged on the circumference of the gas outlet pipe joint; and a pore diameter of an inner hole of the gas inlet pipe joint is smaller than that of an inner hole of the gas outlet pipe joint. According to the flat insertion type gas pipe joint, the ring-shaped grooves are formed in the pipe wall of the gas inlet pipe joint and matched with seal rings, so that a rubber gas pipe can be parallelly inserted into the matched gas inlet pipe joint, the sealing contact area of the rubber gas pipe and the gas inlet pipe joint is increased, the sealing performance is greatly improved, and gas leakage is prevented.
Description
Technical field
The utility model relates to a kind of tracheae pipeline connecting part, specifically a kind of horizontal plug-in type gas-tpe fitting.
Background technique
The gas circuit of using at gaspipe line, big-load trailer at present all needs to use joint to connect in connecting.Existing jointing mostly utilizes the rubber property of tracheae, by interference fit, connect and then use buckle fastening, this kind of Placement be because rubber expands with heat and contract with cold and the natural characteristic such as aging, often working life not long, cause the technological deficiencies such as tracheae gas leakage.
Chinese utility model patent patent No. ZL201120409609.6 discloses a kind of gas-tpe fitting, comprise inflator joint and tracheae female joint, tracheae female joint is provided with tracheae female joint passage, in tracheae female joint passage, be provided with one-way valve, one-way valve comprises valve seat, spool and stage clip, install in tracheae female joint passage valve base sealing, on valve seat, offer the valve opening of conducting tracheae female joint passage, spool is inserted in valve opening, on spool, compared with the end of inflator joint far-end, convex with seal ring, the diameter of seal ring is greater than the diameter of valve opening, compression spring sleeve be located on spool with respect to seal ring place end compared with far-end, one end of stage clip and valve seat are inconsistent fixing, the other end and spool are connected and fixed.This kind of its structure relative complex of joint, is not guaranteeing under the prerequisite of sealing the technical clarification of designs simplification aspect yet.
Summary of the invention
The utility model provides a kind of simple in structure, long service life, has prevented the horizontal plug-in type gas-tpe fitting of gas leakage.
A kind of horizontal plug-in type gas-tpe fitting, comprise tubular configured joint body, in the middle of joint body, be provided with protruding positioning end, positioning end one side is suction tude joint, the other end is steam outlet pipe joint, described suction tude joint tube wall circumference is provided with three or three above annular grooves, and annular groove two ends are equipped with 45 degree inclination angles; Described steam outlet pipe joint periphery is respectively equipped with front and back the first seal ring and the second seal ring arranged side by side; Described suction tude joint endoporus aperture is less than the aperture of steam outlet pipe joint endoporus.This kind arranges annular groove on the tube wall of suction tude joint, because annular groove groove face is parallel to joint body, after annular groove fitted seal circle, connect rubber tracheae, rubber tracheae can be parallel thus is inserted into gas-tpe fitting, improve the airtight area of contact of rubber tracheae and suction tude joint, greatly improved sealability and prevented gas leakage.The 45 degree inclination angle designs at annular groove two ends have facilitated the installation of seal ring, and relatively traditional an angle of 90 degrees mounting structure is more convenient.It is that a kind of double sealing structure has improved the sealing while giving vent to anger greatly that the first seal ring of steam outlet pipe joint periphery and the second seal ring are connected tracheae by two seal rings, prevents gas leakage.Suction tude joint endoporus aperture is less than the aperture of steam outlet pipe joint endoporus in addition, and it is equivalent to, in horizontal plug-in type gas-tpe fitting inside, air-flow has been carried out to a decompression process, prevents that air pressure is too high and the principal fault that causes.
As structure preferably the diameter of the first described seal ring be greater than the second seal ring, the structural type that the sealing degree of depth that is equivalent to the second seal ring is greater than this different sealing degree of depth of the first seal ring has further prevented Leakage Gas.
Described steam outlet pipe joint outer end is provided with annular snap annular groove, and by the cell body cooperation buckle of annular slot, the fastening structure that forms a kind of belt carries out airtight connection to the tracheae of steam outlet pipe joint connection.
The utility model is by arranging annular groove on the tube wall at suction tude joint, fitted seal circle is realized the insertion cooperation suction tude joint that rubber tracheae can be parallel, improve the airtight area of contact of rubber tracheae and suction tude joint, greatly improved sealability and prevented gas leakage.
Accompanying drawing explanation
Be illustrated in figure 1 the utility model horizontal plug-in type gas-tpe fitting sectional structure schematic diagram.
Embodiment
A kind of horizontal plug-in type gas-tpe fitting comprises tubular configured joint body 1 as shown in Figure 1, in the middle of joint body 1, be provided with protruding positioning end 2, positioning end one side is suction tude joint, the other end is steam outlet pipe joint, suction tude joint tube wall circumference is provided with three or three above annular grooves 6, and annular groove 6 two ends are equipped with 45 degree inclination angles; Steam outlet pipe joint periphery is respectively equipped with front and back the first seal ring 3 and the second seal ring 4 arranged side by side; Suction tude joint endoporus aperture is less than the aperture of steam outlet pipe joint endoporus.Steam outlet pipe joint outer end is provided with annular snap annular groove 5.
As structure preferably the diameter of the first seal ring 3 be greater than the second seal ring 4.
