Description
Technical field
The invention belongs to the aerating of CNG gas station and control valve member, be specifically related to a kind of porous road pneumatic tube joint insert row, in order to control CNG gas station instrument wind system and the break-make of pneumatic actuator on CNG trailer.
Background technology
Special CNG gas cylinder trailer arrives after in air entraining substation, by ready-packaged joint, high pressure feed liquor flexible pipe, high pressure return flexible hose, CNG high pressure outlet air flexible pipe, control trachea bundle are connected with hydraulic substation casing, during work, highly pressurised liquid injects in vehicle-mounted gas bomb, and make pressure of the inside of a bottle be maintained at 20MPa, now CNG enters in the surge tank in hydraulic substation casing through gas bomb gas outlet and high pressure outlet air flexible pipe, then passes through pressure piping and is delivered to gas selling machine to CNG automobile aerating.
Having 8 vehicle-mounted gas bombs on CNG trailer, substation instrument wind system connects with CNG trailer pneumatic control bundle, gives vent to anger thus controlling 8 vehicle-mounted gas bombs.
The existing adaptor by compression air access operated pneumatic valve is as shown in Figure 3, assembly divides two parts, every part is respectively connected to operated pneumatic valve and compression air, adaptor has some gas circuits, in using, what control to specify gas circuit is switched on or switched off thus controlling to specify being switched on or switched off of valve, it is achieved to specifying filling vehicle aerating.
The existing snap joint of Fig. 3, two parts assembly is threaded connection, and in using, therefore joint is plastic, the air pressure long term of gases at high pressure and two assemblies, and in using, easy stripped thread, abrasion, cause poorly sealed problem, cause the raising of gas station operation cost.
Summary of the invention
The present invention provides a kind of porous road pneumatic tube joint insert row, sound construction, simple installation.
The technical solution adopted for the present invention to solve the technical problems is: the porous road pneumatic tube joint insert row of the present invention, one end connects air compressor outlet, the other end accesses pneumatic operated valve, it includes fixed support and the built-in snap joint of some spring leafs being arranged on fixed support, fixed support is tabular, it is arranged on support bracket fastened both sides by air flue connection correspondence between the built-in snap joint of each two spring leaf, the built-in snap joint of spring leaf includes shell, shell has coaxial spring leaf installing hole and pore, and hole diameter is identical with gas path pipe diameter；
Spring leaf is installed in spring leaf installing hole, spring leaf includes spring leaf circle and several claws, on shell, the one end near spring leaf installing hole has the fastener projecting inward to hole, spring leaf circle is arranged on below spring leaf circle and conflicts with it, claw one end and the fixing connection of spring leaf circle, the other end bends in spring leaf circle, and the bending section of some claws constitutes a circumference, this circumference is positioned at above pore, and diameter is less than hole diameter；
Buckle structure one end is placed in the housing exterior of spring leaf installing hole side, it is conflicted with spring leaf claw bending section through spring leaf installing hole at the other end, there is in the middle part of buckle structure the ring-shaped depression coordinated with fastener, buckle structure can move up and down along spring leaf installing hole, and buckle structure has through hole and connects with the pore of shell.
In such scheme, described spring leaf has 6 claws.
Further, the built-in snap joint of described spring leaf is arranged on fixed support both sides by nut.
Shell wall in pore arranges packing ring, engages with gas path pipe.
In using, the built-in snap joint of spring leaf of side connects compression air, the other end accesses operated pneumatic valve, install to connect and all use small hose, during installation, press buckle structure, claw is pressed under one end that buckle structure and spring leaf claw are conflicted, making it open, small hose via through holes being inserted air flue, thus realizing the connection of fixed support two ends gas circuit.
Between fixing, the built-in snap joint of spring leaf at two ends fixedly mounts by nut, need to press buckle structure and can realize the installation and removal of two ends small hose in using, simple installation, and simple in construction is less costly.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
Embodiment 1
Referring to Fig. 1, Fig. 2 and Fig. 4, the porous road pneumatic tube joint insert row of the present invention, one end connects air compressor outlet, the other end accesses pneumatic operated valve, it includes fixed support 1 and the built-in snap joint of some spring leafs being arranged on fixed support 1, fixed support 1 is tabular, by air flue 13 connection the corresponding both sides being arranged on fixed support 1 between the built-in snap joint of each two spring leaf, the built-in snap joint of spring leaf includes shell 3, shell 3 has coaxial spring leaf installing hole 4 and pore 5, and pore 5 diameter is identical with gas path pipe and small hose diameter；
Spring leaf is installed in spring leaf installing hole 4, spring leaf includes spring leaf circle 6 and several claws 7, on shell 3, the one end near spring leaf installing hole 4 has the fastener 9 projecting inward to hole, spring leaf circle 6 is arranged on the lower section of fastener 9 and conflicts with it, claw 7 one end and the fixing connection of spring leaf circle 6, the other end bends in spring leaf circle 6, and the bending section 8 of some claws 7 constitutes a circumference, this circumference is positioned at above pore 5, and diameter is less than pore 5 diameter；
