Abstract
The utility model relates to a high-sealing ball valve. The ball valve effectively solves the problem that a valve rod of an existing ball valve is poor in airtightness, the ball valve is prevented from leaking in the use process, and safety of products is ensured. The high-sealing ball valve comprises a valve body (1), a valve rod (2) and a valve core, wherein the valve rod (2) penetrates in the valve body (1) from the upper end, an installing part (3) is fixed at the lower end of the valve rod (2) and connected with the valve core, and the lower end face of the installing part (3) is provided with an annular groove (4). An annular notch (5) is formed in the inner wall of the valve body (1), and an arc elastic piece (6) is arranged in the annular notch (5) and is matched with the periphery of the valve rod (2) in a squeezed mode. Due to the fact that the annular groove is formed in the lower end face of the valve rod, media can act on the annular groove without running to the two sides, and the elastic piece on the inner wall of the valve body has the effects of balance, positioning and guiding on the periphery of the valve rod, so that coaxiality of the valve rod is ensured, and sealing performance is effectively ensured.
Description
Technical field
The utility model relates to a kind of ball valve, particularly relates to a kind of high sealed ball valve.
Background technique
Ball valve is used comparatively general in valve field, therefore sealability can become the technical problem that its emphasis solves all the time, the lower end surface of valve rod is generally plane, therefore, in use, valve rod can be subject to the impact of pressure medium, and pressure is difficult to balance, thereby cause valve rod to depart from center, finally cause sealing to reduce and cause leakage.
Summary of the invention
For the shortcoming and deficiency that overcome background technique, the utility model provides a kind of high sealed ball valve, effectively solves the problem that there is the poor difference of sealing in current ball-valve valve rod place, prevents that revealing from use appearring in valve, guarantees the Security of product.
The technical solution of the utility model is: a kind of high sealed ball valve, comprise valve body, valve rod and spool, valve rod penetrates valve inner from upper end, the lower end of described valve rod is fixed with the assembly department be connected with spool, the lower end surface of described assembly department is provided with circular groove, the inwall of described valve body is provided with annular breach, is provided with the spring sheet of arc in described annular breach, and described spring sheet coordinates with the periphery extruding of valve rod.
Described annular breach is placed with fixed block, and described spring sheet one is connected to the fixed block upper end.
The both sides inwall of described valve body is provided with groove, in described groove, is provided with spring, and the head of described spring is fixed with the diaphragm seal fitted with the assembly department outer surface, and end is connected with the end face of groove.
Described diaphragm seal is by rubber or teflon.
The utlity model has following beneficial effect: by the valve rod lower end surface, circular groove being set, medium can act on this curve bath, can not run to both sides, and the spring sheet by valve interior wall carries out balance, location and leading role to the valve rod periphery, guarantee the coaxality of valve rod, effectively guarantee sealability.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, valve body 1, valve rod 2, assembly department 3, circular groove 4, annular breach 5, spring sheet 6, fixed block 7, groove 8, spring 9, diaphragm seal 10.
Embodiment
Below for accompanying drawing, embodiment of the present utility model is described further:
Shown in figure, a kind of high sealed ball valve, comprise valve body 1, valve rod 2 and spool, valve rod 2 penetrates valve body 1 inside from upper end, the lower end of described valve rod 2 is fixed with the assembly department 3 be connected with spool, and the lower end surface of described assembly department 3 is provided with circular groove 4, and the inwall of described valve body 1 is provided with annular breach 5, be provided with the spring sheet 6 of arc in described annular breach 5, described spring sheet 6 coordinates with the periphery extruding of valve rod 2.When ball valve is used, by circular groove 4 is set on the valve rod lower end surface, medium can act on this curve bath 4, can not run to both sides, and balance, location and leading role are carried out in the 6 pairs of valve rod peripheries of spring sheet by valve interior wall, guarantee the coaxality of valve rod, effectively guarantee sealability.
As shown in the figure, described annular breach 5 is placed with fixed block 7, and described spring sheet 6 one are connected to fixed block 7 upper ends.During installation, spring sheet 6 is arranged on fixed block, spring sheet coordinates with the peripheral extruding of valve rod, and when valve rod is partial to, the spring sheet extrusion produces the purpose that elasticity plays balance.
The both sides inwall of described valve body 1 is provided with groove 8, in described groove 8, is provided with spring 9, and the head of described spring 9 is fixed with the diaphragm seal 10 fitted with assembly department 3 outer surfaces, and described diaphragm seal 10 is by rubber or teflon.End is connected with the end face of groove 8.Ball valve in use, by operating device band ovable valve stem 2, rotate, drive assembly department 3 rotations, diaphragm seal 8 is mounted in spring, and assembly department 3, by diaphragm seal 8 Compress Springs, makes spring all the time in compressed state, therefore the resiliency urged diaphragm seal 8 of its generation contacts with the outer surface of assembly department 3 and realizes the purpose of sealing, therefore can effectively play the effect of sealing, then, in conjunction with the seal ring between valve rod 2 and valve body 1, reach the purpose of double seal.
Claims (4)
1. a high sealed ball valve, comprise valve body (1), valve rod (2) and spool, valve rod (2) penetrates valve body (1) inside from upper end, the lower end of described valve rod (2) is fixed with the assembly department (3) be connected with spool, it is characterized in that: the lower end surface of described assembly department (3) is provided with circular groove (4), the inwall of described valve body (1) is provided with annular breach (5), be provided with the spring sheet (6) of arc in described annular breach (5), described spring sheet (6) coordinates with the periphery extruding of valve rod (2).
2. high sealed ball valve according to claim 1, is characterized in that described annular breach (5) is placed with fixed block (7), and described spring sheet (6) one is connected to fixed block (7) upper end.
