Description
Technical field
The utility model relates to natural gas compressing technical field, the air inlet of specially a kind of natural gas compressor.
Background technology
Natural gas compressor is mainly used in the conveying of natural gas, supercharging, is liquefied gas station, LPG Vehicle Fueling Station, the key equipment at gaseous mixture station.
The operation principle of natural gas compressor is: natural gas enters the entrance of natural gas compressor through snorkel, it is pressurized to 8-12 kilogram in the cylinder of natural gas compressor, cool down simultaneously, remove heat, during less than critical-temperature (temperature of material gaseous state and liquid conversion), these natural gas gases can liquefy, and the gas of liquefaction is by being pumped in pressure vessel storage, therefore can carry and dispense as required, such as dress truck tank, dress civil liquefied gas tank etc..
Wherein, when natural gas enters the air inlet of natural gas compressor through snorkel, it is that the mode being threaded connection is connected between the air inlet pipe of natural gas compressor and snorkel, this results in natural gas and easily leaks out from the screw thread between air inlet pipe and snorkel, poor sealing, once revealing occurs in natural gas, then there is very big potential safety hazard.
Utility model content
The purpose of this utility model is to provide the air inlet of a kind of natural gas compressor, with the problem solving to propose in above-mentioned background technology.
nullFor achieving the above object，The following technical scheme of the utility model offer: the air inlet of a kind of natural gas compressor，Including snorkel and be positioned at the air inlet pipe directly over snorkel，The internal diameter of described air inlet pipe is identical with the internal diameter of snorkel，The external diameter of described air inlet pipe is identical with the external diameter of snorkel，The lower surface of described air inlet pipe is bonded to each other with the upper surface of snorkel，The bottom of described air inlet pipe is cased with a upper joint sleeve，Described upper joint sleeve is connected with air inlet pipe by way of welding，The top of described snorkel is cased with a lower joint sleeve，Described lower joint sleeve is connected with snorkel by way of welding，The mode homogeneous vertical being threaded connection on described upper joint sleeve installs multiple fixing bolt，The screw rod of described fixing bolt runs through upper joint sleeve，The mode that the lower end of the screw rod of described fixing bolt is threaded connection is connected with lower joint sleeve，The lower end of described air inlet pipe is cased with an annular sleeve，The first half of described annular sleeve is connected with air inlet pipe by way of welding，And the first half inner peripheral surface of annular sleeve is bonded to each other with the outer circumference surface of air inlet pipe，The lower half of described annular sleeve is enclosed within snorkel，And the lower half inner peripheral surface of annular sleeve is bonded to each other with the outer circumference surface of snorkel，The position of described annular sleeve is between upper joint sleeve and lower joint sleeve.
Further, described annular sleeve uses stainless steel to make.
Compared with prior art, the beneficial effects of the utility model are: use fixing bolt to link together upper joint sleeve and lower joint sleeve, together with the lower end of air inlet pipe is then fitted tightly with the upper end of snorkel by upper joint sleeve with lower joint sleeve, sealing significantly improves, additionally by arranging annular sleeve, annular sleeve then blocks the junction of air inlet pipe and snorkel, therefore further increases sealing, effectively avoid the generation of natural gas leakage situation, safe and reliable.
Brief description
Fig. 1 is the utility model structural representation.
In figure: 1 snorkel, 2 air inlet pipe, 3 upper joint sleeves, 4 lower joint sleeves, 5 fix bolt, 6 annular sleeve.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole embodiments.Based on the embodiment in the utility model, every other embodiment that those of ordinary skill in the art are obtained under the premise of not making creative work, broadly fall into the scope of the utility model protection.
nullReferring to Fig. 1 the utility model provides a kind of technical scheme: the air inlet of a kind of natural gas compressor，Including snorkel 1 and be positioned at the air inlet pipe 2 directly over snorkel 1，The internal diameter of described air inlet pipe 2 is identical with the internal diameter of snorkel 1，The external diameter of described air inlet pipe 2 is identical with the external diameter of snorkel 1，The lower surface of described air inlet pipe 2 is bonded to each other with the upper surface of snorkel 1，So good airproof performance，Natural gas is difficult to natural gas leaking occur when entering in air inlet pipe 2 from snorkel 1，Then natural gas enters through air inlet pipe 2 in the main body of natural gas compressor，The bottom of described air inlet pipe 2 is cased with a upper joint sleeve 3，Described upper joint sleeve 3 is connected with air inlet pipe 2 by way of welding，The top of described snorkel 1 is cased with a lower joint sleeve 4，Described lower joint sleeve 4 is connected with snorkel 1 by way of welding，The mode homogeneous vertical being threaded connection on described upper joint sleeve 3 installs multiple fixing bolt 5，The screw rod of described fixing bolt 5 runs through upper joint sleeve 3，The mode that the lower end of the screw rod of described fixing bolt 5 is threaded connection is connected with lower joint sleeve 4，Can be by rotary fixing screw bolt 5 so that the lower end of the screw rod of fixing bolt 5 enters further in lower joint sleeve 4，Distance between upper joint sleeve 3 and lower joint sleeve 4 then tapers into，So upper joint sleeve 3 drives air inlet pipe 2 to move down，Lower joint sleeve 4 drives snorkel 1 to move up，Till together with fitting tightly with the lower surface of air inlet pipe 2 until the upper surface of snorkel 1，It is so beneficial to the raising of sealing，The lower end of described air inlet pipe 2 is cased with an annular sleeve 6，The first half of described annular sleeve 6 is connected with air inlet pipe 2 by way of welding，And the first half inner peripheral surface of annular sleeve 6 is bonded to each other with the outer circumference surface of air inlet pipe 2，The lower half of described annular sleeve 6 is enclosed within snorkel 1，And the lower half inner peripheral surface of annular sleeve 6 is bonded to each other with the outer circumference surface of snorkel 1，The position of described annular sleeve 6 is between upper joint sleeve 3 and lower joint sleeve 4，Annular sleeve 6 blocks air inlet pipe 2 and the junction of snorkel 1，Further increase sealing property，Avoid natural gas and the situation of gas leakage occurs from the junction of air inlet pipe 2 and snorkel 1，Safe and reliable.
Further, described annular sleeve 6 uses stainless steel to make, and annular sleeve 6 is not susceptible to situation about damaging because getting rusty, and service life is long.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, being appreciated that and can carrying out multiple change, modification, replacement and modification to these embodiments in the case of without departing from principle of the present utility model and spirit, scope of the present utility model is defined by the appended claims and the equivalents thereof.
