Description
Technical field
The utility model relates to a kind of gas transport valve mechanism, relates in particular to the linkage structure that is used in a kind of fuel gas ball valve valve body is quick with the PE pipe, high leak tightness links to each other.
Background technique
Domestic gas transmission and distribution network uses the PE pipeline on a large scale at present, the valve major part of original PE install pipeline is the PE valve, connect with generally adopting heat-melting butt-joint or electric capacity being connected of pipeline, but reliability, Security are relatively poor, therefore on the PE pipe, also wish to adopt reliability, steel or irony valve that Security is good, but traditional linkage structure or Placement can't be used for being connected of steel or irony valve and PE pipeline.Therefore, the PE pipeline is the important technological problems that current needs solve with being connected of steel or irony gas valve in the gas transmission and distribution.
Summary of the invention
In view of the defective that above-mentioned prior art exists, the purpose of this utility model is the linkage structure that proposes a kind of fuel gas ball valve, realizes quick, high leak tightness attaching.
The purpose of this utility model, to be achieved by the following technical programs: a kind of linkage structure of fuel gas ball valve, the valve body that relates to fuel gas ball valve, be fixed with valve seat in the described valve body, valve base chamber is provided with spheroid, the centre bottom of described spheroid is provided with the positioning shaft that links to each other with the valve body one, the top, center of described spheroid is inserted with valve rod, described valve body top is provided with valve rod base and the sealing seat that links into an integrated entity, described valve rod is connected among the valve rod base, it is characterized in that: described linkage structure comprises the hoop cylinder of one at the set screw-shaped groove of valve body two end interface outer walls and every end, one section of being pressed into of PE joint is socketed on the groove, and described hoop cylinder tightness is socketed on the section of being pressed into of PE joint.
Further, be provided with seal ring between the interface of described valve body and the PE joint.
Further, be provided with the PE sealing film to the PE pipe from valve body outside the described hoop cylinder.
Remarkable result after the technical solutions of the utility model application implementation is: by the PE joint being pressed into and outer hoop, so that the linkage structure of ball valve and PE pipe is compact, good airproof performance, optimized the space hold of product based on above-mentioned linkage structure.
Description of drawings
Fig. 1 is the structural representation of the utility model fuel gas ball valve.
Fig. 2 is the linkage structure schematic representation of the utility model fuel gas ball valve.
Embodiment
Following constipation closes embodiment's accompanying drawing, embodiment of the present utility model is described in further detail, so that technical solutions of the utility model are easier to understand, grasp.
As shown in Figure 1, be a kind of structural representation of fuel gas ball valve.From illustrating as seen, its agent structure is valve body 1, is fixed with valve seat 2 in the valve body 1, and valve base chamber is provided with spheroid 3; The centre bottom of this spheroid 3 is provided with the positioning shaft 4 that links to each other with valve body 1 one, the top, center of this spheroid 3 is inserted with valve rod 5, this valve body 1 top is provided with the valve rod base 6 that links into an integrated entity and sealing seat 7(for being threaded, with further raising sealing), this valve rod 5 just is connected among the valve rod base 6.In the actual operation, rotate drive spheroid 3 deflection several angles by valve rod 5, the PE pipe at valve body 1 two ends is connected; And equally by valve rod 5 drive rotation can so that spheroid 3 with the PE pipe phase compartment at two ends, thereby realize the on-off function of valve.
As the technical characteristics that the utility model is laid special stress on protecting, as shown in Figure 2, be a preferred embodiment of this fuel gas ball valve linkage structure.From illustrating as seen, this linkage structure comprises the hoop cylinder 9 of one at the set screw-shaped groove of 1 liang of end interface outer wall of valve body and every end, and a section of being pressed into 8 of PE joint is socketed on the groove, and hoop cylinder 9 tightness are socketed on the section of being pressed into 8 of PE joint.In addition, be provided with seal ring 10 between the interface of this valve body 1 and the PE joint.From connecting technique, groove is the inherent structure of preprocessing moulding in the ball valve manufacture process, the section of being pressed into 8 of PE pipe then is connected on the groove of this joint by being pressed into process sleeve, since the plasticity of PE pipe self and with the preliminary interlock of groove, again in the peripheral socket of the section of being pressed into hoop cylinder 9 and clamp, make the section of being pressed into of PE pipe and the further interlock of groove and can't stressed drawing and go out.Realize quick attaching with this, have simultaneously higher sealing.
The aesthetic property and the sealing that connect for further improving product, the utility model also is provided with the PE sealing film (shown in Fig. 2 left side) from valve body 1 to PE pipe in hoop cylinder 9 outsides, this PE sealing film can link to each other by the viscose glue sealing in a side of valve body 1, and can connect by heat-melting butt-joint or electric smelting in a side of PE pipe.
By the PE joint being pressed into and outer hoop, so that the linkage structure of ball valve and PE pipe is compact, good airproof performance, also optimized the space hold of product simultaneously based on above-mentioned linkage structure.
In addition to the implementation, the utility model can also have other mode of execution.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
