Abstract
The utility model discloses a spiral tuyere, which comprises an air valve tongue piece, a seal ring and a middle seat and is characterized in that the middle seat comprises an upper middle seat and a lower middle seat, and the center of the middle seat is provided with a through hole. The seal ring is sleeved on the lower middle seat, and the air valve tongue sheet is arranged in the through hole where the lower middle seat is arranged. The air valve tongue sheet is of a T-shaped structure formed by an air seat tongue sheet bottom and an air valve tongue sheet rod, two symmetrical grooves are arranged in the center of one face of the air valve tongue sheet bottom, and the other face of the air valve tongue is connected with the air valve tongue sheet rod. The spiral tuyere is fast in air inlet speed, capable of saving resources and saving use time, good in air tightness and high in safety.
Description
Technical field
The utility model relates to a kind of tuyere, particularly the spiral tuyere.
Background technique
Chinese patent ZL92228987.5 discloses a kind of spiral envelope mouth, and it comprises: loam cake, base, spiral body, soft connecting sheet and leaf membrane; Said loam cake is made up of lid and screw, is provided with internal thread in the said lid and bolt closes the hole, in order to the nail portion bolt of screw and the round body pivot cover that provides a space let said soft connecting sheet; Said center is provided with through hole, is provided with internal thread in the through hole being threadedly connected to the spiral body, the bottom be provided with in addition a larger-diameter sticking part with the inflatable boat welding; Said spiral body is divided into the screw section with a separating part with the Spiral Notebook tagma and reaches screw section down; Should go up the screw section and be provided with outside thread; Can be connected with the internal thread of said loam cake; Should go up nearly separating part place, screw section and be with a ring plate, and make its both spacing become a belled part and supply another round body of soft connecting sheet to be inserted in; Be provided with an annular groove at said separating part and said screw section junction point down, it is built-in with one can become airtight envelope ring fully with annular groove; It is provided with outside thread in the screw section down, can lock with the screw-internal thread fit in the base, and said spiral body center is provided with a vent, passes to down the place, screw section and is provided with a catch, and several manholes are arranged on this catch; One end of said soft connecting sheet is connected with the bolt jointing part of said loam cake, and the belled part of screw section is connected to avoid loam cake to lose on the other end and the said spiral body; Said leaf membrane is covered on the catch of screw section under the said spiral body, and its center utilizes a soft coupler body to be fixed on the catch, and after the inflation, thereby this leaf membrane can automatically return to the flow direction that the preceding state may command of inflation charges into gas because of its elasticity.The envelope mouth structure of this structure is complicated, and intake velocity is slow and tightness is relatively poor, and is comparatively time-consuming when inflating.
The model utility content
The purpose of the utility model is to provide a kind of intake velocity faster for the deficiency that solves above-mentioned existing technology, saves resource, saves service time simultaneously, and tightness is better, the spiral tuyere that margin of safety is high.
To achieve these goals, the spiral tuyere that the utility model designed comprises air valve tongue piece, seal ring and middle seat, it is characterized in that said in seat comprise upper middle seat with down in seat, middle seat center is provided with through hole; On the seat, the air valve tongue piece was located at down in the through hole at middle seat place during seal ring was enclosed within down; The air valve tongue piece is the T type structure that is made up of gentle clack valve sheet bar at the bottom of the air valve tongue piece, and the center of one side is provided with the groove of two symmetries at the bottom of the air valve tongue piece, and another side is connected with air valve tongue piece bar.
Be equipped with screw thread on said upper middle seat and the middle down seat.
The spiral tuyere that the utility model obtains, intake velocity is faster, saves resource, saves service time simultaneously, and tightness is better, and margin of safety is high.
Description of drawings
Fig. 1 is embodiment's overall structure schematic representation;
Fig. 2 is embodiment's part explosive view;
Fig. 3 is embodiment's air valve tongue piece structural representation.
Among the figure: air valve tongue piece 1, seal ring 2, middle seat 3, upper middle seat 4, down at the bottom of the seat 5, air valve tongue piece 6, air valve tongue piece bar 7, groove 8, through hole 9.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Embodiment:
Like Fig. 1, Fig. 2, shown in Figure 3, the spiral tuyere that the utility model provides comprises air valve tongue piece 1, seal ring 2 and middle seat 3, said in seat 3 comprise upper middle seat 4 with down in seat 5, middle seat 3 centers are provided with through hole 9; On the seat 5, air valve tongue piece 1 was located at down in the through hole 9 at middle seat 5 places during seal ring 2 was enclosed within down; Air valve tongue piece 1 is the T type structure that is made up of 6 gentle clack valve sheet bars 7 at the bottom of the air valve tongue piece; The center of 6 one sides is provided with the groove 8 of two symmetries at the bottom of the air valve tongue piece; Another side is connected with air valve tongue piece bar 7; When blows air over air valve tongue piece 1, blow open more easily, can effectively reduce resistance and reach the purpose of ventilating fast.Be equipped with screw thread on said upper middle seat 4 and the middle down seat 5.The spiral tuyere of this structure, intake velocity is faster, saves resource, saves service time simultaneously, and tightness is better, and margin of safety is high.
