Abstract
The utility model of entrance and exit joint for gas booster is the most suitable one for connecting the gas booster and main loop. The utility model adopts a screwed joint with shoulder and a flange which is matched with the shoulder of the screwed joint and can be rotated relative to the screwed joint as the connecting piece; the screwed joint can be rotated relative to the flange which is convenient not only for the fixation and installation of the flange but also for screwing down the screwed joint to effectively prevent leakage; moreover, the structure of the utility model is simple; the installation and maintenance is convenient and saves time and labor; the effect is excellent and the production cost is greatly reduced. Therefore, the utility model is very practical.
Description
One, technical field
The utility model relates to gas pressure regulator, governor and imports and exports connecting joint, is particularly useful for being connected of gas pressure regulator, governor and major loop.
Two, background technique
The Placement of present used crucial accessory pressure governor connecting joint of combustion gas regulator and major loop mainly contains two kinds of forms: a kind of is that flange connects, and another kind is to be threaded.Two kinds of multi-form being connected processing and assembling, cost control, maintaining and preventing that from all there is difference in various degree the dielectric leakage aspect.In general, the pressure governor that is threaded, volume is little, cost is low, uses more general under the working condition of low pressure small flow.Leak but easily produce, especially do not increasing under the movable joint situation, maintaining is difficulty comparatively, in case go wrong, will integral body tears open greatly greatly and unloads, and can not fix a breakdown at short notice.But because it is with low cost, volume is little, and it is little to take up room, and therefore uses more.Flange connects that to have an assembling quick, easy to maintenance, leak-proof good, adapts to the pressure range broad, especially uses the most general in the big flow of mesohigh field.But the pressure governor that is threaded of its manufacture cost model function more of the same race will exceed a lot, and volume is also bigger than normal, corresponding also the wanting greatly that take up room, and this just makes MANUFACTURER and user have to take into account to some extent when production and type selecting.How to accomplish to save cost, can just just naturally put again in face of the people with the I﹠ M maintenance.Italy Shanghai flies difficult to understand be threaded and flange connects the half-way house of pressure governor between the two, adopt thread head flange plate type jointing, make problem that certain improvement be arranged, but after we collect assembling and consumers' opinions, pinpoint the problems and be not solved, reason is that they are threaded when flange connects transition at handle, not tight in the double thread course of working to tolerance control, usually producing screw thread has put in place, the flange bolt hole is not in place or crossed head, or works as flange bolt and just in time put in place, and the screw thread that is connected with homophony is also very loose, do not have the leakproof effect, cause with other links yet and can not normally assemble.
Three, technology contents
1. goal of the invention
In view of the deficiency that prior art exists, the purpose of this utility model provides a kind of flange connecting head that can make and tightens, and can make the contraposition of flange bolt hole again, plays the gas pressure regulator, governor of leakproof effect and imports and exports connecting joint.
2. technological scheme
The utility model gas pressure regulator, governor is imported and exported connecting joint, and it is matched by an inipple that has through hole and a shoulder and one and this inipple shoulder and merges in relative rotation flange and form.
3. technique effect
The utility model gas pressure regulator, governor is imported and exported connecting joint, be best suited for being connected of gas pressure regulator, governor and major loop, relatively rotate body, both solved the orientation problem in flange bolt hole because inipple and flange changed into, solved the problem that thread connecting joint is tightened again, effectively played the leakproof effect, and installed simply, maintaining is convenient, time saving and energy saving, effective, saved cost of production greatly, have practicability widely.
Four, description of drawings
Accompanying drawing is that the utility model gas pressure regulator, governor is imported and exported the connecting joint structural drawing.
Five, embodiment
The utility model will be further described below in conjunction with an embodiment in the accompanying drawing:
The utility model gas pressure regulator, governor is imported and exported connecting joint, and it is made up of inipple 1 and rotation flange 2, and inipple 1 middle part has through hole, and afterbody is provided with a right angle shoulder, and rotation flange 2 matches with inipple 1 right angle shoulder and can relatively rotate.
Claims (1)
1. gas pressure regulator, governor is imported and exported connecting joint, it is characterized in that: it by an inipple (1) that has through hole and a shoulder and one and this inipple (1) shoulder match merging in relative rotation flange (2) form.
