Abstract
The invention discloses a connection structure of a gas ball valve and relates to the valve body of the gas ball valve. According to the invention, valve seats are fixed in the valve body; a ball is arranged between the valve seats; a positioning shaft integrally connected with the valve body is arranged at the center bottom of the ball; a valve rod is inserted into the center top of the ball; a valve rod seat and a seal seat both connected integrally with each other are arranged on the top of the valve body; and the valve rod penetrates through the valve rod seat. Especially, the connection structure comprises threaded grooves formed on the outer walls of connections at the two ends of the valve body and two hoop barrels arranged at the two ends respectively; a press-in section of a PE connector is sleeved above the grooves; and the hoop barrels are tightly sleeved in the press-in section of the PE connector. The gas ball valve is characterized in that the PE connector is pressed in and hooped externally based on the connection structure, so that the connection structure of the ball valve and a PE pipe is compact and good in tightness, and therefore, the space utilization of the product is optimized.
Description
Technical field
The present invention relates to a kind of gas transmission valve mechanism, relate 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 that original PE pipeline is provided with is the PE valve; Connect with generally adopting hot melt butt joint or electric capacity being connected of pipeline; But reliability, Security are relatively poor, therefore on PE pipe, also hope employing 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 existing technology exists, the objective of the invention is to propose a kind of linkage structure of fuel gas ball valve, realize quick, high leak tightness attaching.
The object of the invention; To be achieved through following technological scheme: a kind of linkage structure of fuel gas ball valve, relate to the valve body of fuel gas ball valve, said valve body internal fixation has valve seat; Valve base chamber is provided with spheroid; The centre bottom of said spheroid is provided with the positioning shaft that links to each other with the valve body one, and the top, center of said spheroid is inserted with valve rod, and said valve body top is provided with valve rod base and the sealing seat that links into an integrated entity; Said valve rod is connected among the valve rod base; It is characterized in that: said linkage structure comprises the hoop tube of one at the set screw-shaped groove of valve body two end interface outer walls and every end, and the section of being pressed into of PE joint is socketed on the groove, and said hoop tube tightness is socketed on the section of being pressed into of PE joint.
Further, be provided with seal ring between the interface of said valve body and the PE joint.
Further, be provided with the PE sealing film to the PE pipe outside the said hoop tube from valve body.
Remarkable result after the technological scheme application implementation of the present invention is: through the PE joint being pressed into and binding round, make that the linkage structure of ball valve and PE pipe is compact, good airproof performance based on above-mentioned linkage structure outward, optimized the space hold of product.
Description of drawings
Fig. 1 is the structural representation of fuel gas ball valve of the present invention.
Fig. 2 is the linkage structure schematic representation of fuel gas ball valve of the present invention.
Embodiment
Following constipation closes embodiment's accompanying drawing, and specific embodiments of the invention is done further to detail, so that technological scheme of the present invention is easier to understand, grasp.
As shown in Figure 1, be a kind of structural representation of fuel gas ball valve.Visible from illustrating, its agent structure is a valve body 1, and valve body 1 internal fixation has valve seat 2, 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 that links into an integrated entity 6, and (both are for being threaded with sealing seat 7; 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, the PE pipe at valve body 1 two ends is connected through valve rod 5; And equally can make spheroid 3 with the PE pipe phase compartment at two ends, thereby realize the on-off function of valve by valve rod 5 rotary driving.
As the technical characteristics that the present invention lays special stress on protecting, as shown in Figure 2, be a preferred embodiment of this fuel gas ball valve linkage structure.Visible from illustrating, this linkage structure comprises the hoop tube 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 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 technology; Groove is the inherent structure of preprocessing moulding in the ball valve manufacture process; The section of being pressed into 8 of PE pipe is then through being pressed on the groove that technology is socketed in this joint; 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 tube 9 and clamp, make the PE pipe the section of being pressed into and the further interlock of groove and can't stressed drawing and go out.Realize quick attaching with this, have higher sealing simultaneously.
For further improving aesthetic property and the sealing that product connects; The present invention also is provided with the PE sealing film (shown in Fig. 2 left side) from valve body 1 to PE pipe in hoop tube 9 outsides; This PE sealing film can link to each other through the viscose glue sealing in a side of valve body 1, and can connect through hot melt butt joint or electric smelting in a side of PE pipe.
Through the PE joint being pressed into and binding round, make that the linkage structure of ball valve and PE pipe is compact, good airproof performance based on above-mentioned linkage structure outward, also optimized the space hold of product simultaneously.
Except that the foregoing description, the present invention 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 present invention's scope required for protection.
