Description
Technical field
This utility model relates to aerating apparatus field, is specifically related to a kind of NGV air filling gun head.
Background technology
Natural gas filling station refers to provide to gas-fueled vehicles (NGV) and large-scale CNG substation car the place of fuel with compressed natural gas (CNG) form.Gas in natural gas line typically first passes through preposition purified treatment, removes the sulfur in gas and moisture content, then by compressor bank, by 0.1-1.0Mpa, pressure is compressed to 25Mpa, finally by gas selling machine to vehicle aerating.There is very big pressure in the natural gas used due to combustibility, explosion hazard and natural gas filling station that natural gas existence is stronger, therefore natural gas equipment must have preferable stability and sealing, and conventional air filling gun head is many based on NGV air filling gun head.
The design of existing NGV air filling gun header structure is complex, in wherein valve body front end embeds gas-adding pipe, valve rear end is provided with ball, and valve body outer sheath is provided with spring housing, spring housing front end is provided with spring and coordinates with gas-adding pipe, and spring housing rear end arranges two confinement groove positions and ball engagement.And there is the biggest potential safety hazard in this conventional NVG air filling gun head: owing to the wall trench inwall on valve body and ball can not be fitted completely, cause the easy pressure-rupturable of the support level bottom wall trench, thus ball drops out, cause natural gas leaking；When NVG air filling gun head inserts, confinement groove position is big with ball friction, and resistance is big, thus inserts difficulty.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of NGV air filling gun head, solves existing NGV air filling gun head and easily occurs that valve body ruptures the problem causing losing heart, leak gas, and the problem that air filling gun head Cat-in resisting force is excessive.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of NGV air filling gun head, including valve body, the air inlet pipe being connected with valve body, the spool being arranged in valve body and valve seat, the spring cup being sheathed on outside valve body, the first spring it is provided with between described air inlet pipe and spool, the second spring it is provided with between described valve body and valve seat, the 3rd spring it is provided with between described spring cup and air inlet pipe, described valve rear end is provided with holding tank, sliding sleeve it is provided with in holding tank, ball it is provided with in sliding sleeve, described spring housing and ball opposite position are provided with the insertion groove accommodating ball, described insertion groove front end is provided with the pressing groove compressing ball, described pressing groove rear end is additionally provided with lead-over groove.
Now with NGV air filling gun head wall trench bottom only use the projection of band gradient to support ball, support section is the weakest, arrange holding tank replace wall trench, can effectively strengthen the intensity of ball installation place.Accommodate ball by arranging sliding sleeve, it is to avoid ball directly clashes into and compresses bottom holding tank, simultaneously facilitate installation and change, be effectively prevented because of valve body rupture, ball drops out the situation generation causing losing heart, leak gas.The activity of spring housing carries out existing between spacing location, pressing groove and insertion groove bigger slope difference by pressing groove and insertion groove to ball, causes spring housing to slide difficult.Lead-over groove is set in pressing groove rear end, reduces the rolling between pressing groove and insertion groove of the gradient between pressing groove and insertion groove, beneficially ball, replace more convenient.
Further, described sliding sleeve outer wall is fitted with holding tank, and described sliding sleeve inwall binding face is consistent with ball.
Sliding sleeve inwall binding face is consistent with ball, more preferably solves existing NGV air filling gun head wall trench and arranges the problem that gradient projection causes being caused valve body to rupture by excessive stresses.
Further, the fit clearance of described valve body, air inlet pipe, spool and valve seat is provided with sealing ring；Described sealing ring material is polyurethane.
Fit clearance at valve body, air inlet pipe, spool and valve seat is provided with sealing ring, strengthening the sealing of NGV air filling gun head, this exterior seal ring uses polyurethane material, substantially improves the sealing property of sealing ring, increase the service life of air filling gun head, reduce cost to a certain extent.
The beneficial effects of the utility model are:
This utility model simple in construction, the suitability is strong, and stability is high, not only makes NGV air filling gun head insert more convenient, laborsaving, and substantially increases the structural strength of ball installation site, solves the crackly problem of valve body, it is therefore prevented that disappointing, the generation of gas leakage situation.

Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with being specifically illustrating, this utility model is expanded on further.
A kind of NGV air filling gun head, as shown in Figure 1-Figure 3, including valve body 1, the air inlet pipe 2 being connected with valve body 1, the spool 3 being arranged in valve body 1 and valve seat 4, the spring cup 5 being sheathed on outside valve body 1, the first spring 6 it is provided with between described air inlet pipe 2 and spool 3, the second spring 7 it is provided with between described valve body 1 and valve seat 4, it is provided with the 3rd spring 8 between described spring cup 5 and air inlet pipe 2, described valve body 1 rear end is provided with holding tank 9, sliding sleeve 10 it is provided with in holding tank 9, ball 11 it is provided with in sliding sleeve 10, described spring housing 5 and ball 11 opposite position are provided with the insertion groove 12 accommodating ball 11, described insertion groove 12 front end is provided with the pressing groove 13 compressing ball 11, described pressing groove 13 rear end is additionally provided with lead-over groove 14.
Described sliding sleeve 10 outer wall is fitted with holding tank 9, and described sliding sleeve 10 inwall binding face is consistent with ball 11.
