Description
Technical field
The utility model relates to valve field, is specifically related to a kind of valve gap of big-and-middle-sized industrial ball valve.
Background technique
Ball valve is mainly used in blocking or connect the liquid medium in valve body, also can be used for the regulating and control of liquid medium, and ball valve includes ball valve body, ball core, valve rod and seal ring.Ball valve body needs the structure being arranged to split usually, so that ball core is loaded in valve body, therefore ball valve body include the valve body of settling ball core and with the valve gap of valve body by Flange joint, the mounting groove installed for seal ring is equipped with inside valve body and valve gap, ball valve after installation is connected by the conflict of the seal ring in mounting groove with ball core, thus form the sealing of ball core and ball valve body.But poorly sealed situation easily appears in the connection of valve gap and valve body in prior art, ball valve is caused in use to produce leakage.
Model utility content
For problems of the prior art, the purpose of this utility model is to provide a kind of valve gap promoting sealing property of ball valves.
To achieve these goals, the technical solution adopted in the utility model is: a kind of valve gap, comprise end cap body, end cap body is provided with passage, passage comprises feed pathway and liquid outlet channel, end cap body is provided with near feed pathway end the first flange be connected with valve body, end cap body is provided with near liquid outlet channel end the second flange be connected with valve body, it is characterized in that: described end cap body is convexly equipped with the sealing surface coordinated with valve seal on the end face of liquid outlet channel, is also provided with soft seal pad between sealing surface and valve body; Described sealing surface is provided with the bar groove be interspersed, and the cross section of described bar groove is " V " shape; Described sealing surface is provided with the positioning hole connecting soft seal pad.
The utility model is also set to further, and described positioning hole is provided with 4.
The utility model is also set to further, and described end cap body is provided with the safety relief hole be communicated with feed pathway.
The utility model is also set to further, and described first flange and the second flange are provided with some mounting holes, and described mounting hole is fixing threaded hole.
The beneficial effects of the utility model: bar groove is set by the sealing surface that coordinates with valve seal at end cap body, when the soft seal pad be arranged on like this between end cap body and valve body is squeezed, part soft seal pad will be absorbed in bar groove, increase the exposure level of sealing surface and soft seal pad, make sealing effect better; And for being interspersed on sealing surface, there is not straight-through connectivity slot in bar groove, the possibility that leakage is occurred by bar groove can be avoided, the cross section of bar groove is " V " shape, makes soft seal pad more easily be absorbed in bar groove, also makes the sealing of soft seal pad and bar groove tighter; Meanwhile, sealing surface is provided with the positioning hole of the soft seal pad that is located by connecting, and close soft packing can be prevented to be moved, and ensures the leakproofness of sealing further.Above-mentioned setting makes the better tightness of valve gap and valve body, ensures the sealing of ball valve further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side view of the present utility model;
Fig. 3 is the A portion enlarged view in the utility model Fig. 1.
Number in the figure implication: 1-end cap body; 11-first flange; 12-second flange; 13-sealing surface; 131-bar groove; 132-positioning hole; 2-passage; 21-feed pathway; 22-liquid outlet channel; 3-soft seal pad; 4-safety relief hole; 5-fixing threaded hole.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
Below with reference to Fig. 1 to Fig. 3, the utility model is described.
A kind of valve gap, comprise end cap body 1, end cap body 1 is provided with passage 2, passage 2 comprises feed pathway 21 and liquid outlet channel 22, end cap body 1 is provided with near feed pathway 21 end the first flange 11 be connected with valve body, end cap body 1 is provided with near liquid outlet channel 22 end the second flange 12 be connected with valve body, described end cap body 1 is convexly equipped with the sealing surface 13 coordinated with valve seal on the end face of liquid outlet channel 22, the soft seal pad 3 of ring is also provided with between sealing surface 13 and valve body, sealing surface 13 and valve body pass through compression fit, and soft seal pad 3 is pressed on the sealing both realizing between the two, soft seal pad 3 can be rubber sheet gasket, described sealing surface 13 is provided with the bar groove 131 be interspersed, and the cross section of described bar groove 131 is " V " shape, described sealing surface 13 is provided with the positioning hole 132 connecting soft seal pad 3, and described positioning hole 132 is provided with 4.
End cap body 1 is provided with the safety relief hole 4 be communicated with feed pathway 21, and safety relief hole 4 connecting valve external body, carries out pressure release by Decompression valves to ball valve, ensures the Security that ball valve uses.
First flange 11 and the second flange 12 are provided with some mounting holes, described mounting hole is fixing threaded hole 5, because end cap body 1 is in " work " font, and two end flange are at a distance of nearer, therefore flange operating difficulties when being connected with pipeline and valve body with nut by bolt, after the mounting hole of the first flange 11 and the second flange 12 is set to fixing threaded hole 5, only need screws in bolt from the outside of end cap body 1 and just conveniently can realize Flange joint, also there is the advantages such as structure is simple, reliability is strong.
The beneficial effects of the utility model: bar groove 131 is set by the sealing surface 13 that coordinates with valve seal at end cap body 1, when the soft seal pad 3 be arranged on like this between end cap body 1 and valve body is squeezed, part soft seal 3 pads and will be absorbed in bar groove 131, increase sealing surface 13 and the exposure level of soft seal pad 3, make sealing effect better; And, bar groove 131 is for being interspersed on sealing surface 13, there is not straight-through connectivity slot, the possibility that leakage is occurred by bar groove 131 can be avoided, the cross section of bar groove 131 is " V " shape, make soft seal pad 3 more easily be absorbed in bar groove 131, also make soft seal pad 3 tighter with the sealing of bar groove 131; Meanwhile, sealing surface 13 is provided with the positioning hole 132 of the soft seal pad 3 that is located by connecting, and soft seal pad 3 can be prevented to be moved, and ensures the leakproofness of sealing further.Above-mentioned setting makes the better tightness of valve gap and valve body, ensures the sealing of ball valve further.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improvement of above-mentioned hypothesis and modification also should be considered as protection domain of the present utility model.
