Abstract
The utility model relates to the technical field of gas pressure reducing valves, in particular to a gas pressure reducing valve easy to unlock. The novel air inlet valve comprises a pressure reducing valve body and an air inlet pipe communicated with the pressure reducing valve body, wherein a locking wheel is arranged at one end of the air inlet pipe, a threaded part is formed on the locking wheel, a transmission wheel is further matched with the locking wheel, the locking wheel and the transmission wheel are meshed or driven with each other, the transmission wheel is fixed on a transmission shaft, a hand wheel or a handle is arranged at the other end of the transmission shaft, and the transmission shaft is installed on the air inlet pipe through a support. The hand wheel or handle on the transmission shaft is rotated by hand to drive the transmission wheel to rotate, and the transmission wheel drives the locking wheel meshed or driven with the transmission wheel to rotate, so that the air inlet of the pressure reducing valve is locked at the interface of the main valve of the gas tank. Because the operation is carried out outside the handle ring of the gas tank, the condition that hands are damaged is avoided, and the lever principle of the transmission shaft is utilized to easily drive the locking wheel to rotate, so that the locking purpose is realized.
Description
Technical field:
The utility model relates to the coal gas compression release valve technical field, refers in particular to a kind of coal gas compression release valve that is easy to tear open lock.
Present widely used coal gas compression release valve locking wheel, diameter is less, on one side and its be that the reduction valve another side is the gas-tank main valve, people's hand difficulty is held locking wheel, even held reluctantly, because the handle cycle space on gas-tank top is too little, when holding locking wheel and wanting to tighten, need take bigger strength, accidentally sliding hand defensive position will be run into the handle circle, the hand of damaging so old man, women are not easy to tighten locking wheel, makes troubles for our daily life.Conventional instrument does not make again, does not conform to hand with pipe wrench, big spanner reluctantly yet, is easy to damage the danger that locking wheel causes gas leakage in this way yet.
The model utility content:
The purpose of this utility model is exactly to provide a kind of coal gas compression release valve that is easy to tear open lock at the deficiency of prior art existence.
To achieve these goals, the technical solution adopted in the utility model is: it comprises a reducing valve body and the suction tude that is communicated with reducing valve body, be provided with locking wheel at suction tude one end, and this locking wheel forms threaded piece, locking wheel also is combined with a drive wheel, and locking wheel and drive wheel be to form a transmission structure, and drive wheel is fixed on the transmission shaft, be provided with the turn-knob device at the transmission shaft the other end, transmission shaft is installed on the suction tude by support.
After adopting said structure, because locking wheel is combined with drive wheel, and locking wheel and drive wheel intermesh or transmission, drive wheel also is fixed on the transmission shaft, just can drive drive wheel with handwheel on the hand rotating drive shaft or handle rotates, drive wheel drives the locking wheel rotation with its engagement or transmission again, and then the suction port of reduction valve is locked the into main valve jointing of gas-tank.Because operation is to carry out in the handle circle outside of gas-tank, the situation of having avoided hand to damage, and utilized this lever principle of transmission shaft can easily drive locking wheel and rotated, realize the locking purpose.
Description of drawings:
Fig. 1 is a junction structure schematic representation of the present utility model;
Fig. 2 is the connection diagram of the utility model and gas-tank main valve.
Embodiment:
See shown in Fig. 1,2, the technical solution adopted in the utility model is: it comprises a reducing valve body 1 and the suction tude 2 that is communicated with reducing valve body 1, be provided with locking wheel 3 at suction tude 2 one ends, and this locking wheel 3 forms threaded piece 5, locking wheel 3 also is combined with a drive wheel 6, and locking wheel 3 and drive wheel 6 intermesh or transmission, drive wheel 6 is fixed on the transmission shaft 7, be provided with turn-knob devices 8 such as handwheel or handle at transmission shaft 7 the other ends, transmission shaft 7 is installed on the suction tude 2 by support 9.Just can drive drive wheel 6 with handwheel on the hand rotating drive shaft 7 or handle and rotate, drive wheel 6 drives locking wheel 3 rotations with its engagement or transmission again, and then suction port 10 locks of reduction valve is advanced the main valve jointing of gas-tank.When dismantling reduction valve, the opposite direction rotation hand wheel or the handle that need only according to above-mentioned locking direction are detachable reduction valve.
Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and are included in the utility model claim.
