Abstract

The utility model relates to a ball valve structure, which mainly adopts the following structure: a valve ball of a valve body is embedded with a middle shaft having the subface provided with a brake block; each corner of the brake block is provided with a tangent plane to make both front and back ends form into tips; a limit groove is arranged outside the bearing of the valve body for a driver platform provided with a plurality of screw holes to span, and then a bolt is screwed in the screw hole to be propped up against the limit groove of the bearing so as to combine and locate both the driver platform and the limit groove; therefore, cleaning liquid can flow along each tangent plane of the brake block of the middle shaft and meets at the end part so as to clean out residual liquid at the back end of the brake block; in addition, as for selecting drive mode for ball valve, replacement-type driver platform can be adopted to realize fast assembly, thereby substantially increasing cleanliness of ball valve and reducing replacement cost during changing drive mode.

Description

Ball-valve structure

Technical field

The utility model relates to a kind ofly can significantly promote the ball valve cleanliness, and saves the ball-valve structure of the replacement cost of driving mode when changing.

Background technique

Now, the application of valve body is quite extensive, with food, industries such as pharmacy or living skill, health and cleanliness for valve body require quite high, therefore, health with valve body its how to clean to avoid contaminated liquid really be to be important problem, so take a broad view of ball valve design in the streets, big polyphyly is researched and developed at how lift-off seal usefulness, for example use the ball pad as sealing configuration, but the cleanliness for valve body itself requires not as good as the health valve body, there is no any design of cleaning valve body of implementing, and then easily because of the valve ball in the ball valve in opening and closing when rotating, liquid entrainment is residual and influence health to the gap of valve ball and ball-and-socket, cause ball valve can't be applied to above-mentioned industry, therefore, designed by the structure that has the dealer can implement cleaning at ball valve, see also Fig. 1, Fig. 2, it is U.S. Pat 5,842,683 structural representation, put one in the ball-and-socket 2 of its valve body 1 and have the valve ball 3 of caulking groove 4, and be provided with the cleaning solution that connects ball-and-socket 2 in the outside and go into,

water outlet

5,6, the top then is provided with an axis 7, the brake slipper 8 of this axis 7 is to be embedded in the caulking groove 4 of valve ball 3, open and close with control valve ball 3, and then when cleaning ball valve, can inject cleaning solution by cleaning solution water inlet 5, with flushing ball-and-socket 2, and make residual liquid discharge by cleaning solution water outlet 6; But, see also shown in Figure 3, because the two chimeric place gap minimum of the caulking groove 4 of the brake slipper 8 of axis 7 and valve ball 3, the cleaning solution comparatively difficulty that flows herein, and the brake slipper 8 of this axis 7 is a strip, and each bight is a right angle, when wash liquid stream during through the brake slipper 8 of axis 7, easily, cause the not good disappearance of ball valve cleanliness because of its back side screening area greatly produces delay, and can't really residual liquid be rinsed well.In addition, the axis driving mode summary of ball valve can be divided into manual drives or driver drives at present, when with driver drives, valve body then need have a driver platform for the installing driver, if during with manual drives, then must not have the driver platform, therefore, valve body is also at the different driving mode and individual design, but the ball valve design that cooperates the driver platform with manually-operable being arranged now in addition, see also shown in Figure 4ly, is No. 86221825 patent case of novel application number, it is straight forming one driver platform 10 on valve body 9, selects to drive with manual drives or driver 11 for the user; Only this one designs when the user selects with driver drives, though can conveniently directly install driver, but when selecting with manual drives, fixed and bulky driver platform promptly causes each ball valve quite to take up room on arranging, cause the disappearance of other arrangement of components difficulty, but if directly select the ball valve that designs at manual drives for use, when in-plant equipment is made automatic updating and is desired with driver drives, then must change the ball valve that is suitable for, if hyperphoric ball valve quantity is more, then cause the significantly increase of user cost and the waste of time that changes the outfit.

Summary of the invention

The purpose of this utility model provides a kind of ball-valve structure, and it mainly is the axis that is to set on the valve ball of this valve body a bottom surface tool brake slipper, and each angle of its brake slipper all has a bigger tangent plane; By this, when cleaning ball valve, can change the flow path of cleaning solution, make the cleaning solution of the axis of flowing through, carrying over each angle tangent plane by the front end of brake slipper flows, and cross in rear end, because the tangent plane at each angle constitutes a tip in the place, end, and significantly reduce the screening area of front end and back end, therefore, cleaning solution is cleaned the residual liquid of brake slipper rear end, and do not produce trapping phenomena, reach certain cleaning ball-and-socket significantly to promote the Practical Benefit of ball valve cleanliness.

Another purpose of the present utility model is to offer several restraining grooves in the bearing outside of this valve body, and supply a driver platform to be cross-placed on, and this driver platform is offered the screw of several corresponding restraining groove positions, screw in to be resisted against the restraining groove of bearing, with driver platform assembling location for the bolt tool; By this, the user can be required according to the axis driving mode, when manual drives, with driver platform removal, to dwindle valve volume, and be easy to the spatial configuration of other assembly or pipeline, when desire is made automatic updating with equipment, can directly install the driver platform for setting up driver, drive axis with automation, and need not change whole ball valve, reach the Practical Benefit of significantly saving replacement cost and time.

The purpose of this utility model is achieved in that a kind of ball-valve structure, put in this valve body one by in shaft-driven valve ball, it is characterized in that: installing one has the driver platform of through hole on this valve body, and the through hole of this driver platform places for locating piece, with assembling anchor drive platform.

Wherein, this valve body is provided with the bearing of an outside tool restraining groove and puts for the driver platform, and supplies the locating piece overhead in restraining groove, assembling anchor drive platform.

Wherein, the perforation inner face of this driver platform convexes with jacking block, and this jacking block is cross-placed on the bearing of valve body.

Wherein, the through hole of this driver platform is a screw, and locating piece is the bolt tool.

Wherein, this axis has a brake slipper, and the bight of brake slipper has tangent plane.

Wherein, each bight of this brake slipper all has a tangent plane, makes its front and back ends generally be a tip.
