Abstract

The utility model discloses an improved chucking relief valve for petroleum gas stove, comprising a valve casing, the air inlet, the pressure reduction, and the air outlet in the valve casing. The air inlet part comprises an intake port which is matched with a card gas cylinder and the parts in the intake port. The utility model is characterized in that the air inlet part also comprises an intake port which is matched with the air hose of the atmosphere hose and an air gate bolt, a spring, a sealing element, a thread sleeve, and a hose coupling which are arranged on the intake port. Compared with the existing pressure reducing valve, the utility model has the advantage that any gas bottle which can be selected and used at present provides the convenience for use.

Description

A kind of reduction valve of cassette petroleum gas stove

The utility model belongs to the component of a kind of cassette petroleum gas (or coal gas) stove, particularly has a reduction valve that cuts off function.

The reduction valve of the present cassette petroleum gas stove that generally uses, structure comprise valve casing with and interior air inlet, three parts reduce pressure, give vent to anger, wherein induction part has only a suction port, in order to cooperate with cassette gas cylinder (i.e. 220 gram bottles), use the big gas cylinder of air hose air feed all can not cooperate with it for other, this has brought limitation to steam stove with the gas scope, and is also not quite convenient in the use.

The purpose of this utility model provides a kind of reduction valve of improved cassette petroleum gas stove, can select to use cassette gas cylinder or with other gas cylinder of air hose air feed, can overcome the defective of prior art.

The utility model is achieved in that a kind of reduction valve of cassette petroleum gas stove, comprise valve casing with and interior air inlet, decompression, three parts of giving vent to anger, wherein induction part comprises a suction port that can cooperate with cassette gas cylinder and valve bolt thereof, valve spring, Sealing, the relief portion branch comprises relief chamber, air inlet/outlet, glued membrane and backplate up and down thereof, pressure adjusting spring, the decompression lever, outlet gas part comprises adjusting screw rod, Sealing, snorkel, it is characterized in that described induction part also comprise a suction port that can cooperate with big gas cylinder air hose with and on the valve bolt, valve spring, Sealing, connect swivel nut, hose coupling.

Such scheme has another suction port that can cooperate with big gas cylinder air hose again because induction part has a suction port that can cooperate with cassette gas cylinder, so can select to use any gas cylinder at present, this has convenience in the use.

Below in conjunction with accompanying drawing the utility model is done to describe more specifically.

Fig. 1 is the schematic representation of a kind of scheme of the utility model.

Fig. 2 is A-A sectional view of Fig. 1.

Fig. 3 is B-B sectional view of Fig. 1.

With reference to Fig. 1～Fig. 3, this reduction valve, comprise the valve casing 1 that assembles by several portions with and interior air inlet, decompression, three parts of giving vent to anger, wherein induction part comprise a suction port 2 that can cooperate with cassette gas cylinder with and on valve bolt 3, valve spring 4, Sealing 5～6, the relief portion branch comprises relief chamber 7, inlet hole 8, air outlet hole 9, glued membrane 10 and on, following backplate 11,12, pressure adjusting spring 13, decompression lever 14, outlet gas part comprises adjusting screw rod 15, Sealing 16～19, snorkel 20, feature be described induction part also comprise a suction port 21 that can cooperate with big gas cylinder air hose with and on valve bolt 22, valve spring 23, Sealing 24～26, connect swivel nut 27, hose coupling 28.

In the time will using cassette gas cylinder, unscrewing swivel nut 27 allows valve bolt 22 close suction port 21, the valve bolt 3 of suction port 2 of packing into behind the cassette gas cylinder is opened, petroleum gas enters relief chamber 7 from inlet hole 8, after relief chamber 7 decompressions, enter air outlet hole 9, at this moment outward winding behind the adjusting screw rod 15, petroleum gas is sent to the burner of steam stove from snorkel 20; In the time will using big gas cylinder, withdraw from cassette gas cylinder and close suction port 2 by valve bolt 3, the air hose of big gas cylinder is with after joint 28 is connected, screwing swivel nut 27 opens valve bolt 22, petroleum gas enters air outlet hole 9, and behind the adjusting screw rod 15 of at this moment outwarding winding, petroleum gas is sent to the burner of steam stove from snorkel 20.

Claims
