The present invention is used for solving foregoing invention purpose technical scheme: a kind of nozzle of the Wen's mixing tube be used to being connected to gas-cooker, described nozzle have an inner blast tube, have one can contact by it closed hole of described internal channel on its sidewall.This hole is used for the gas leakage test, and the passage blocking device can stop up described blast tube by it.Owing to adopting this technical scheme, make the gas leakage of gas-cooker detect the more convenient to operate of test.
According to above-mentioned basic technical scheme, the present invention also has following attached technical characterictic, to reach further technique effect.
Open near the narrow of the above inner blast tube of tube wall in described hole, and like this, blocking device is easier to be stopped up passage with blocking device, thereby make the gas leakage of gas-cooker detect the more convenient to operate of test.
Described hole can be by the sealing of sliding part, and after gas leakage detected, the sliding part that using slides is arranged at the nozzle outside sealed the hole, makes the " locked in " operation of the transfer passage of the whole combustion gas after test become easier.
Described sliding part is a sleeve pipe, and sleeve pipe is easily processed, and is with low cost, and is combined well with the outer surface of nozzle, makes test sealing work afterwards easier.
Hole on described nozzle is an elongated slot, makes in the hole space spacious by contrast, handled easily.
Being provided with one on the outer surface of described nozzle is used for making an elastic component to rest the shaft shoulder that seals thereon described hole, after the gas leakage test, by the elastic energy that stores in elastic component, will be pushed into for the sliding part of sealing the position of blind hole, such design makes " locked in " operation simple.
Described elastic component is a helical spring, and is easily fixing and with low cost.
One end of nozzle is provided with the screw thread that is connected for described Wen's mixing tube, by this screw thread, both connects together, and makes easy to connect and good airproof performance.
The combustion gas mixing arrival end place that is connected with described nozzle of described Wen's mixing tube is provided with an air conditioning air door, to enter into the air capacity of described Wen's mixing tube according to required adjusting, improves the efficiency of combustion of combustion gas.
The end place that is connected with described Wen's mixing tube of nozzle has the diameter that presets, described Wen's mixing tube has one greater than the described diameter that presets diameter at its combustion gas mixing arrival end, be used for propping up from opposite side the sliding part in the described hole of self-closed under the promotion of elastic component elastic energy storage, play spacing effect.
Another shaft shoulder is formed at the diameter that presets of nozzle and is connected between air conditioning air door on the combustion gas mixing arrival end of described Wen's mixing tube.
Used the gas-cooker of nozzle of the present invention, the gas leakage test of this gas-cooker is able to more convenient carrying out.
Compared with prior art, the present invention has the following advantages: the nozzle in technical scheme of the present invention be architecture advances nozzle, be arranged on the sidewall of this nozzle for the hole of carrying out the gas leakage test, make in the gas range gas leakage test process, blocking device has facilitated test operation to a great extent more easily near the gas circulation passage.
Further, the hole that is used for leak-testing on the nozzle in the present invention test can be sealed by the locking device that automatically resets that progress of the present invention improves design after test, opens or the operation of blind hole has greater flexibility, more saves time.

Description of drawings of the present invention is as follows:
Fig. 1 is that instrument connection of the present invention is in the central cross-sectional view under opening-wide state.
Fig. 2 is that instrument connection of the present invention is in the stereogram under opening-wide state.
Fig. 3 is that instrument connection of the present invention is in the central cross-sectional view under closed state.
Fig. 4 is that instrument connection of the present invention is in the stereogram under closed state.
The specific embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described, as shown in Figures 1 to 4, the nozzle 2 of the Wen's mixing tube 1 be used to being connected to gas-cooker of the present invention, this nozzle interior is provided with a blast tube 3, this blast tube 3 comprises channel section and the relatively narrow and small channel section of diameter that diameter is larger, be provided with a closed hole 4 for the gas leakage test on the sidewall of nozzle 2, passage blocking device 5 can stop up blast tube 3 by it.
As shown in Fig. 1-2, in order to be more prone to that blast tube 3 is stopped up and carries out leak-testing, the hole 4 that is used for test open on the tube wall near diameter near relatively narrow and small channel section.
After gas leakage detects, on nozzle 2, thereby the hole 4 of test use needs the blocked complete channels that passes to the burner (not shown) that forms, the gas-cooker (not shown) just can realize its normal function, for the " locked in " operation that makes the blast tube 3 after test is more prone to, as shown in Fig. 3 and Fig. 4, the hole 4 that is used for leak-testing on nozzle 2 can be after gas leakage detects, and is sealed by a sliding part 6 pairs of holes that are arranged at slidably the nozzle outside.Be connected and coordinate with nozzle 2 for convenient, in embodiment, sliding part 6 is sleeve pipes, and sleeve pipe is easily processed, and is with low cost, and is combined well with the outer surface of nozzle 2, makes test sealing work afterwards easier.
For the action of stopping up blast tube 3 in the gas leakage test process is more prone to operation, in embodiment, as shown in Fig. 1 and Fig. 2, on nozzle, the hole 4 of test use is an elongated slot, makes space spaciousness by contrast, handled easily in the hole in.
Being provided with one on the outer surface of described nozzle 2 is used for making an elastic component 7 to rest the shaft shoulder 8 that seals thereon described hole, after the gas leakage test, by the elastic energy of compressed elastic component 7 interior storages, will be pushed into for the sliding part 6 of sealing the position of blind hole.As shown in Figures 1 to 4, in embodiment, what elastic component 7 adopted is a helical spring, easily fixing and with low cost.But, can realize other elastic components of compressed energy-storage, as, gum sleeve, jump ring etc. are also within protection domain of the present invention.
As shown in Fig. 1 and Fig. 3, an end of nozzle 2 of the present invention is provided with the screw thread that is connected for described Wen's mixing tube 1, by this screw thread, both connects together, and makes easy to connect and good airproof performance.
Usually in the pipeline configuration of gas-cooker, in order to regulate the ratio of the front combustion gas of burning and air, combustion gas mixing arrival end 9 places that are connected with nozzle 2 at Wen's mixing tube 1 all are provided with an air conditioning air door 10, to enter into the air capacity of described Wen's mixing tube 1 according to required adjusting, improve the efficiency of combustion of combustion gas.As shown in Fig. 1-4, an end that is connected with Wen's mixing tube 1 of nozzle 2 has the diameter that presets, described Wen's mixing tube 1 has one at its combustion gas mixing arrival end 9 and presets the diameter of diameter greater than this, be used for propping up from opposite side the sliding part 6 in the described hole 4 of self-closed under elastic component 7 promotes, carry out spacing to it.
As shown in Figure 3 and Figure 4, in embodiment, be used for elastic component 7 is carried out another spacing shaft shoulder 11 from opposite side, be formed at the diameter that presets of nozzle 2 and be connected between air conditioning air door 10 on the combustion gas mixing arrival end 9 of described Wen's mixing tube 1.
The combustion gas transfer tube (being generally copper pipe) that nozzle of the present invention is connected in existing gas-cooker between Wen's mixing tube, thereby make the gas leakage test of existing gas-cooker be able to more convenient carrying out.
