Abstract

The utility model relates to an adjustable gas safety flow controller, composed of a body, a base, a support bar whose top is provided with an obstruction object, and a control knob which can press and shock the obstruction object. The both ends of the body are communicated with an input and an outlet air passages by a valve mouth; the base is connected with the body by a screw thread; the support bar is rotary on the base by the screw thread, and the support bar extends in the valve mouth of the body; the support bar extends in the inner part of the body, and the circumference of the obstruction object is sheathed with a spring; the part of the support bar, which extends outside the base, is sheathed with a screw ring used for fixing the support bar; the extending end of the support bar is in riveted connection on a cap. The utility model has the advantages of convenient adjustment of air flow, firm positioning of the support bar, no large offset of obstruction objects, and good anti-leakage effect.

Description

Adjustable gas safe traffic controller

The utility model relates to a kind of adjustable gas safe traffic controller, belongs to the air transporting arrangement annex.

No. 75206535, existing Taiwan patent " adjustable gas safe traffic controller " is temporarily transferred the purpose that whole obturator reaches the variation gas flow though its structure can reach, and has following shortcoming:

1, adjust the button bottom and be provided with groove, utilize the set projection of groove central authorities to grip rotation, so that adjust gas flow, but the projection volume is little, is difficult for controlling, rotation inconvenience.

2, adjusting button is with the screw thread rotation advance and retreat, and rotates the no good fixed sturcture in back, loosening voluntarily easily.

3, used obturator is offset a side easily, locatees bad.

Thereby influence leak preventing effect, can't be accurate, closed gas in time.

The purpose of this utility model is that a kind of adjustable gas safe traffic controller will be provided, its good leak-proof effect, can be accurately closed gas in time, safe and reliable.

The purpose of this utility model is achieved in that adjustable gas safe traffic controller, but there are the support bar of obturator and the control knob of crimping bump obturator to be constituted by body, base, top, the body both sides are connected with the input and output air flue with valve port, base is connected with body with screw thread, support bar is combined on the base with screw thread and stretches in the valve port of body, support bar is with spring around stretching into body interior branch and obturator, the support bar protuberate basic unit partly is with the volution that the fixed support bar is used, and the support bar external part is riveted on the cap head.

The utility model advantage: on the cap head that the utility model is convenient to grip because of the support bar external part is riveted on, be exposed at the base outside, it is convenient to rotate, so regulate gas flow easily; After the support bar positioning of rotating, can make its firm stable by the volution rotation, and can not become flexible; Around obturator, be wound with spring, make it not have bigger skew, so good leak-proof effect.

The utility model concrete structure is provided by following examples and accompanying drawing thereof.

Fig. 1 is the utility model diagrammatic cross-section;

Fig. 2 is the utility model sectional perspective exploded view;

Fig. 3 is a rotary supporting rod time action synoptic diagram among Fig. 1;

Describe in detail below in conjunction with accompanying drawing:

Referring to the adjustable gas safe traffic of Fig. 1-3 controller, the support bar 23 of obturator 12 is arranged and be positioned at the control knob 11 that to press on the body 1 by bump obturator 12 by body 1, base 2, top and constituted, body 1 both sides are respectively with input air flue 13 and the output airway 14 of being threaded, body 1 center is provided with to be run through body 1 and is positioned at valve port 15 in the middle of two air flues, is provided with and obturator 12 sealing rubber pad 16 of crimping mutually at valve port 15 peripheries; The base 2 that has center screw 22 is connected with body 1 with screw thread 21 by sealing gasket 17, support bar 23 stretches out in body 1, passing screw 22 sealing gaskets 24 is combined on the base 2 with screw thread, it is characterized in that support bar 23 stretch into part and obturator 12 in the body 1 around be with the location volution 26 that spring 2L support bar 23 protuberate basic units 2 parts are with fixed support bar 23 usefulness in the lump, the end face of volution 26 is mutually closely connected with the bottom surface of base 2, and the external part of support bar 23 is riveted on the cylindrical cap being convenient to grip 27.

Obturator 12 is that a spheroidite utilizes the rotation of support bar 23 can change the distance of 15 of obturator 12 and valve ports in the utility model.

When the utility model uses, as shown in Figure 3, loosening earlier location volution 26, make between itself and the base 2 a suitable spacing is arranged, grip cap head 27, rotary supporting rod 23 can make support bar 23 lifting in base 2, change the distance of 15 of obturator 12 and valve ports, after distance adjustment finishes, will locate volution 26 again and screw, location volution 26 is close on the bottom surface of base 2, like this, support bar 23 promptly can't rotate again and locate.
