Abstract
The utility model discloses a valve for a gas poly ethylene (PE) pipe. The gas PE pipe is a transmission pipeline used for a city gas transmission and distribution low voltage pipe network. The valve for the gas PE pipe is characterized in that the valve for the gas PE pipe is a steel ball valve which is connected with the gas PE pipe in a sealed mode, and an O-shaped sealing ring is arranged between a connector of the gas PE pipe and the valve body end portion of the steel ball valve. Particularly, the steel ball valve is a double-piston sealing type ball valve device. According to the ball valve, a special connecting structure is adopted, and the ball valve can be introduced into the city gas transmission and distribution low voltage pipe network. On one hand, reliability, safety and long service life of the ball valve are favorable for being brought into full play. On the other hand, connecting tightness and convenience of assembly and connection between the ball valve and the gas PE pipe are improved.
Description
Technical field
The utility model relates to a kind of gas transport valve mechanism, relates in particular to a kind of valving for the connection of gas transmission ﹠ distribution low-pressure pipe network or compartment PE pipe.
Background technique
Present gas transmission ﹠ distribution low-pressure pipe network uses the PE pipeline on a large scale, the valve of original PE install pipeline is most of moulds crossover sub connection steel valve for the PE valve or by two steel, connect with generally adopting heat-melting butt-joint or electric smelting being connected of pipeline, but the reliability of PE valve, Security is relatively poor and working life is shorter, to mould the cost of mode of crossover sub higher and adopt the steel valve to add two steel, and construction inconvenience, therefore on the PE pipe, also wish to adopt reliability, the steel that Security is good or iron valve, but these Placements can't be used for being connected of steel valve or iron valve and PE pipeline, therefore, PE pipeline valve Array selection is the present technical issues that need to address 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 to propose a kind of valve for combustion gas PE pipe, realizes the low-cost break-make control of PE pipeline.
The purpose of this utility model, to be achieved by the following technical programs: a kind of valve for combustion gas PE pipe, described combustion gas PE pipe is the transfer conduit of gas transmission ﹠ distribution low-pressure pipe network, it is characterized in that: the valve of described combustion gas PE pipe is the steel ball valve, and described steel ball valve links to each other with the combustion gas PE seal of tube.
Further, the described steel ball valve ball-cock device that is the double-piston sealed type.
Further, be provided with the O RunddichtringO between the valve end of the joint of described combustion gas PE pipe and steel ball valve.
Remarkable result after the technical solutions of the utility model application implementation is: adopt special linkage structure so that ball valve is introduced gas transmission ﹠ distribution low-pressure pipe network, the reliability, Security and the long lifetime that on the one hand are conducive to bring into play ball valve, improved on the other hand with the PE pipe be connected tightness and attaching convenience.
Description of drawings
Fig. 1 is the structural 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.
The utility model innovation has proposed a kind of valve for combustion gas PE pipe, and combustion gas PE pipe is the transfer conduit of gas transmission ﹠ distribution low-pressure pipe network.Especially, the valve of this combustion gas PE pipe is the steel ball valve of double-piston sealed type, and this steel ball valve links to each other with the combustion gas PE seal of tube.As preferred version, be provided with O type circle between the joint of this combustion gas PE pipe and the valve end of steel ball valve.
As shown in Figure 1, be the detailed structural representation of this kind 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.
From linkage structure: it 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.When implementing to connect, 8 of the sections of being pressed into of this PE pipe are connected on by being pressed into process sleeve on the groove of 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 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.
Adopt special linkage structure so that ball valve is introduced gas transmission ﹠ distribution low-pressure pipe network, the reliability, Security and the long lifetime that on the one hand are conducive to bring into play ball valve, improved on the other hand with the PE pipe be connected tightness and attaching convenience.
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.
