Description
Technical field
The present invention relates to the rifle head in liquified natural gas loading technique field, particularly a kind of LNG Liquefied natural gas of annotating.
Background technique
LNG Liquefied natural gas (LNG), is a kind of energy of clean, colleges and universities, and the LNG industry of China is in the flourish stage.Along with the apply continuous construction with LNG Vehicle Fueling Station of country to clean fuel automobile, the demand of LNG filling machine is also constantly increased.
LNG air filling gun head is the important component part of LNG filling machine.At present, user generally uses is the 1169-60B type rifle head that U.S. PARKER company produces, and not only cost of production is high for this rifle head, and easily gas leakage in using process, and user can not field maintenance, can only return-to-factory maintenance.The Qiang Touhe U.S. PARKER II type rifle head that the domestic Qiang Toushi U.S. JC-CARTER company using subsequently produces, but the air displacement of these two kinds of rifle heads is inadequate, and the aerating time is long, affects aerating efficiency.
Chinese patent 201220651238.7 discloses natural gas rifle head, connecting base and exhaust nozzle are connected as a single entity, connecting base has the cavity that tapped hole has with exhaust nozzle and communicates, on exhaust nozzle, cover has seal ring, on exhaust nozzle, have four exhaust ports that communicate with its cavity, on exhaust nozzle, cover has seal ring.Although this structure is simple, in high pressure situation, its sealing effect is still undesirable, and natural gas leaking easily occurs, and causes security incident.
And for example, Chinese patent 200720078261.0 discloses LNG filling device, there is following problem in its structure: the seal ring rapid wear that liquid feeding is robbed, the working life of seal ring is short, cause thus liquid feeding rifle to produce the problems such as leakage, the user cost of liquid feeding rifle is high, and in use exists potential safety hazard.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, the rifle head of a kind of simple in structure, good sealing effect and the filling LNG Liquefied natural gas of shortening aerating time is provided.
Object of the present invention is achieved through the following technical solutions: a kind of rifle head of the LNG Liquefied natural gas of annotating, it comprises valve head, bonnet, valve rod assembly, air outlet adapter, bend pipe and air input joint, valve head is the through-hole structure that two ends have step trough, in the step trough of valve head one side, bonnet is installed, valve head opposite side and air outlet adapter are connected, air outlet adapter outer cover is equipped with nut, nut is stuck on the step being arranged on air outlet adapter outer wall, the internal thread that is arranged at nut inner side is connected with the outside thread that is arranged at valve head outside, air outlet adapter is hollow structure, between air outlet adapter and valve head, be provided with valve rod assembly, the front end of valve rod assembly coordinates with valve head, the rear end of valve rod assembly coordinates with air outlet adapter inner side, between air outlet adapter and air input joint, by bend pipe, be connected.
Described valve head and the place of being connected of bonnet are also provided with Sealing.
Between described valve head and valve rod assembly, be also provided with seal ring.
The present invention has the following advantages:
1, one end of bend pipe arranges air input joint, and the other end arranges air outlet adapter, and air outlet adapter arranges valve rod assembly and valve head, and it is simple in structure, easily manufactured.
2, valve head respectively and Sealing and seal ring are set between bonnet and valve rod assembly, makes rifle head have good sealing when work, improves the Security of rock gas filling.
3, valve rod assembly is large with valve head air displacement, is conducive to shorten the aerating time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1-valve head, 2-bonnet, 3-Sealing, 4-valve rod assembly, 5-seal ring, 6-air outlet adapter, 7-nut, 8-bend pipe, 9-air input joint.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described, but protection scope of the present invention is not limited to the following stated.
As shown in Figure 1, a kind of rifle head of the LNG Liquefied natural gas of annotating, it comprises valve head 1, bonnet 2, valve rod assembly 4, air outlet adapter 6, bend pipe 8 and air input joint 9, valve head 1 has the through-hole structure of step trough for two ends, in the step trough of valve head 1 one sides, bonnet 2 is installed, valve head 1 opposite side and air outlet adapter 6 are connected, air outlet adapter 6 outer cover are equipped with nut 7, nut 7 is stuck on the step being arranged on air outlet adapter 6 outer walls, the internal thread that is arranged at nut 7 inner sides is connected with the outside thread that is arranged at valve head 1 outside, air outlet adapter 6 is hollow structure, between air outlet adapter 6 and valve head 1, be provided with valve rod assembly 4, the front end of valve rod assembly 4 coordinates with valve head 1, the rear end of valve rod assembly 4 coordinates with air outlet adapter 6 inner sides, between air outlet adapter 6 and air input joint 9, by bend pipe 8, be connected.
Valve head 1 is also provided with Sealing 3 with the place of being connected of bonnet 2; Between valve head 1 and valve rod assembly 4, be also provided with seal ring 5.
In use, air input joint 9 is connected with tank body or device for storing liquid, valve head 1 is connected with outside liquid container, carry out aerating, the air displacement of valve head 1 is larger, has significantly shortened the aerating time.
