Abstract
The utility model discloses a ball valve, including valve body, spherical case and rotating switch, be provided with the water hole on the spherical case, spherical case is upper to be provided with at least twice seal ring in crossing the water hole top, is provided with the intra -annular gasket of embedding stagnant water on the valve body. The utility model has the advantages of it is following and effect: through the cooperation of seal ring with the gasket, can plug up case upper portion, avoid water to spill from the clearance between rotating switch and the valve body to increase this ball valve's leakproofness, reduced the drainage after the long -term use of ball valve. The new mechanical structure of this scheme utilization adopts the combination of seal ring and gasket, has reached sealed effect.
Description
Technical field
This utility model relates to valve technology field, is specifically related to a kind of ball valve.
Background technology
Ball valve (ball valve), defined in standard GB/T21465-2008 " valve term " be: opening and closing element (spheroid) is driven by valve rod, and the valve rotated around ball valve axis.Also can be used for regulation and the control of fluid, the most firmly seal, between V-type ball valve its V-type core and metal seat valve of pile-up welding hard alloy, there is the strongest shearing force, be particularly well-suited to the medium of fibre-bearing, small solid material etc..And multi-pass ball valve not only can control the interflow of medium, shunting and the switching flowed on pipeline flexibly, also can close arbitrary passage simultaneously and make two other passage be connected.
The Chinese patent of Application No. 201520038569.7, discloses a kind of wall-hung boiler ball-valve dedicated applied widely.Spool, the water inlet being located at valve body one end that the valve rod that it includes valve body, be located in valve body is connected with valve rod lower end, it is located at the outlet of the valve body other end, is located at the valve gap of outlet end, described valve gap is provided with aluminium-plastic tube joint, described valve gap and aluminium-plastic tube joint are split-type structural, if being provided with arterial highway sealing member between described valve gap and aluminium-plastic tube joint.
This patent is disadvantageous in that, valve core rotation and when opening valve, owing to radius when radius ratio when spool is opened is closed is little, and water flow impact pressure is bigger, current easily ooze out from the junction between ball valve and valve sidewall, and then flow up the gap location from being connected between rotating switch with valve body and spill, the most after long-term use, space between switch and valve body becomes big, is more prone to the phenomenon occurring leaking.
Utility model content
The purpose of this utility model is to provide the ball valve that a kind of minimizing is leaked.
Above-mentioned technical purpose of the present utility model has the technical scheme that
A kind of ball valve, including valve body, spherical valve core and rotating switch, described spherical valve core is provided with water hole, spherical valve core is positioned at water hole and is provided above at least twice seal ring, and valve body is provided with the diaphragm seal embedded in seal ring.
By coordinating of seal ring and diaphragm seal, it is possible to avoid water to spill from the gap between rotating switch and valve body, thus add the sealing of this ball valve, decrease the drainage after ball valve life-time service.
Of the present utility model it is further arranged to: be provided with on the bottom surface of seal ring and sealing gasket that diaphragm seal is conflicted.
By this setting, sealing gasket can increase the sealing of this ball valve further, it is to avoid water spills between seal ring and diaphragm seal.
Of the present utility model it is further arranged to: described sealing gasket is made up of elastomeric material.
Rubber has certain elasticity so that this sealing gasket has preferable sealing effectiveness, further increases the sealing of this ball valve.
Of the present utility model it is further arranged to: being provided with rectangular recess on spherical valve core, rotating switch is plugged in rectangular recess.
It is plugged in rectangular recess by rotating switch, achieves the rotation to ball valve by turning rotating switch.
Of the present utility model it is further arranged to: described rotating switch includes the grafting block being plugged in rectangular recess and for the wing nut driving grafting block to rotate, described wing nut is connected by screw with grafting block, is provided with elastic washer between screw and grafting block.
Elastic washer has certain elasticity, it is possible to makes screw more tight with the combination of grafting block, thus adds stability when wing nut uses.
Of the present utility model it is further arranged to: wing nut is provided above the capping that plastics are made, and the sidewall of capping has been provided with cover slot.
By playing the setting of cover slot so that when wing nut is dismantled by needs, it is possible to facilitate instrument deeply capping to be levered up, facilitate the unloading process to wing nut, accelerate work efficiency.
In sum, this utility model has the advantages that coordinating by seal ring and diaphragm seal, it is possible to avoids water to spill from the gap between rotating switch and valve body, thus adds the sealing of this ball valve, decreases the drainage after ball valve life-time service.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
A kind of ball valve, including valve body 1, spherical valve core 2 and rotating switch 3, described spherical valve core 2 is provided with water hole 21, spherical valve core 2 is positioned at water hole 21 and is provided above at least twice seal ring 22, and valve body 1 is provided with the diaphragm seal 11 embedded in seal ring 22.By coordinating of seal ring 22 and diaphragm seal 11, it is possible to spherical valve core 2 top is blocked, it is to avoid water spills from the gap between rotating switch 3 and valve body 1, thus add the sealing of this ball valve, decrease the drainage after ball valve life-time service.
The sealing gasket 4 conflicted with diaphragm seal 11 it is provided with on the bottom surface of seal ring 22.By this setting, sealing gasket 4 can seal the gap between seal ring 22 and diaphragm seal 11, it is to avoid water spills between seal ring 22 and diaphragm seal 11, increases the sealing of this ball valve further.
