Description

Supply gas box and the pipe connecting structure of a kind of cooling and warming
Technical field
The invention belongs to heating and refrigeration field, and in particular to supply gas box and the pipe connecting structure of a kind of cooling and warming.
Background technology
Existing indoor cooling and warming mode has air-conditioning, the mode of the interior electric heating floor heating for having a heating wire, so on State mode and the problems such as interior is distinguished and admirable greatly, high energy consumption and the feature of environmental protection are poor, inconvenient maintenance be present.
The content of the invention
The purpose of the present invention is to provide a kind of aspirating pipeline system architecture of cold and heat supply to solve the above problems.
The present invention above-mentioned technical purpose technical scheme is that:
Supply gas box and the pipe connecting structure of a kind of cooling and warming, including hollow square box body, pipe end are connected with box body And communicate with box chamber and supplied gas or the gas main of return-air for box chamber, be connected to it is adjacent with the box wall of the box body of connection gas main or The branch's tubule for transferring out the gas of box intracavitary on relative box wall, the gas main and branch's tubule removably connect In on the box body, the bridge joint neck for gas main described in bridge joint or branch's tubule, the bridge joint are fixed with outside the box body Neck includes open upwards vallecular cavity, groove bottom wall and groove outer wall, and offering upper end through the groove outer wall on the groove outer wall opens Mouthful the embedding mouth of bridge joint, correspond to the embedding mouth of the bridge joint on the box wall and offer the stomata communicated with box chamber.
Gas main and branch's tubule enter pneumatic transmission in order to as homogeneously as possible different not on same box wall wall In branch's tubule.
Preferably, institute's stomata collar extension leads mouth, the gas main and branch's tubule and the box wall provided with funnelform The port of docking, which is provided with, to be used to fix the positioning fastener for leading mouth described in pipe end and front end insertion.
Preferably, the positioning fastener includes being fixedly arranged on the gas main or branch's tubule with built-in spring On outer tube, the activity in the outer tube and being sheathed on the gas main or branch's tubule is accessed by outer tube rear end set Cutting ferrule, it is fixedly arranged on outer tube front end and can be at least partly embedded in the seal head for leading mouth;The activity card sets front end is butted on institute State the rear end of spring.
Preferably, the activity card sets rear end is connected with the stable disk of expansion, the stable disk is confined to described In vallecular cavity and it is butted on the groove inside outer wall, and a stable disk side panel inconsistent at least with groove outer wall for arc along leading Edge, the activity card sets front end are limited in the outer tube.
The design that edge is led using arc is not only convenient for loading, at the same reduce contact area also allow for take out when it is further Also can easily it be taken out when extruding increased force.
Preferably, the stomata is higher than the groove bottom wall, the embedding mouth of bridge joint is square orifice, the gas main and branch Outside of the tubule at least with the embedding mouth telescoping part of the bridge joint is square.
When the design of above-mentioned square structure improves installation and mounted configuration stability, be not easy by air pressure impulsive force And the influence deflection or loosening of external structure, Stability Analysis of Structures, accurate positioning is installed.
Preferably, the outer tube front end is provided with slot portion, the seal head be sheathed on it is outer in the slot portion The tapered rubber sleeve in surface, rubber sleeve rear end diameter are more than the outer tube external diameter.
The above-mentioned seal head diameter larger with respect to outer tube, it can ensure that seal head is blocked hermetically sealedly as far as possible and lead mouth, it is ensured that Sealing.
Preferably, slot portion front end exceeds the seal head.
Said structure can avoid flexible soft seal head from all living stomata, and guarantee slot portion is to connect firmly with gas opening Touch, it is ensured that effectively positioning, ventilation.
Offered preferably, corresponding to orifice position on the box body outer wall and upwardly extending for guiding the seal head to lead It is the tipper being gradually increased by aperture upper end to box body top surface groove depth to enter to the importing conduit led on mouth, the guide groove road Road.
It is easy to dock with stomata with from top to bottom aligning, it is simple, convenient.
Preferably, the seal head rear sleeve is provided with the suitable guide pin bushing of hard, the suitable guide pin bushing includes and seal head side face Fitting suitable guide face, with seal head rear end face coordinate end limit face and be integrally connected to along guide face and hold limit face junction and to It is outer extend be used for it is spacing along face.
Because seal head is elastic, the setting along guide pin bushing can effectively prevent seal head from squeezing because frictional force is excessive importing It is unfavorable for installing in conduit, smoothly demand position can be led by auxiliary seal head along guide pin bushing, while also functions to spacing effect, Under normal circumstances, seal head is installed to lead mouth in place after, do not contacted with box body outside wall surface along guide pin bushing, once seal head and slot portion When having disengagement trend or having deviate from a part, imported due to spacing along face gear outside conduit so that seal head travels downwardly process In seal head is also extruded on the cascaded surface between slot portion and outer tube front end backward on the way, so as to ensure seal head be in need Position is asked to ensure sealing, while install again without first adjusting without departing from slot portion front end.
In summary, the invention has the advantages that:
1st, the application is by metope indoors or ground arrangement vacuum line, then i.e. to vacuum line transporting low temperature or High Temperature Gas Body,(Gas can be refrigerant(Refrigerant)The form to be exchanged heat by evaporative phase-change obtains being refrigeration that other modes obtain Heating heating gas), gas conducts heat to indoor and then cooling and warming effect during passing through pipeline.The application Supplied gas or return-air, and uniformly conveyed from branch's tubule to indoor wall or wall section, the application to box of supplying gas by gas main Supply gas box and pipeline use must be detachably connected mode, the dismounting mode clamping of the application is convenient, passes through and positions engaging Part is from top to bottom snapped on groove outer wall and the embedding mouth of bridge joint, because the top pressure of spring acts on once being reached during downwards funnelform When leading mouthful, then press-in is led intraoral and docked with stomata automatically for pipe front end, and is sealed by seal head, it is necessary to only be needed when being removed Pipe is pulled back, due to the position-limiting action of stable disk so that spring is extruded, and positions fastener and pipe end takes off from mouth is led Go out, the process for pulling back and carrying upwards realizes dismounting.
2nd, the application is simple in construction, easy to maintenance, and part also reuses, and cost is low, optionally installs, and can adjust Installation position, it is applied widely, it is practical, and cost is low.
