Abstract
The utility model provides a ball valve, which comprises a valve body. The left end and the right end of the valve body are both provided with end covers. Valve gaskets are arranged between the valve body and the end covers, the upper side of the valve body is connected with a cylinder, a ball valve core is arranged in the middle of the valve body, the ball valve core is connected with a gear shaft arranged in the middle of the cylinder, a sealing part is arranged between the cylinder and the gear shaft, the left end and the right end of the cylinder are both provided with plastic end covers respectively connected with rotating piston racks through springs, the rotating piston racks are both meshed with the gear shaft, and an air inlet is arranged on the lateral wall of the cylinder arranged between the rotating piston racks. The air which has the advantages of being convenient in collection, free of pollution and the like is adopted as the power source, thereby facilitating wide application of the ball valve in the fields of fabrication and service.
Description
Technical field
The utility model relates to a kind of ball valve, be used to steep mould, industry such as light industry, washing, food, medical treatment are made, carry neutral gas or flowing mediums such as liquid, washing agent on the industrial automation production line of Service Industry, belong to valve technology field.
Background technique
Old product before the ball valve is to be main with the plane valve seal.Plane sealing is to utilize planar sealing pad to contact with the valve port circumferential plane; In the process of valve opening and closure, owing to receive pneumatic percussion, planar sealing pad is when impacting valve port; Form impact injury easily, thereby influence the working life and the usability of product.Its shortcoming: valve seal is unreliable, poor durability.
Summary of the invention
The purpose of the utility model provides that a kind of valve seal is reliable, the ball valve of good endurance.
In order to achieve the above object, the technological scheme of the utility model provides a kind of ball valve, comprises valve body; The right ends of valve body all is provided with end cap, is provided with the valve seal pad between valve body and the end cap, and the upside of valve body connects cylinder barrel; The valve body middle part is provided with the ball valve core, and the ball valve core is connected at the gear shaft at cylinder barrel middle part, is provided with Sealing between cylinder barrel and the gear shaft; The right ends of cylinder barrel all is provided with plastic end cover; Plastic end cover connects a rotary piston tooth bar through spring respectively, and the rotary piston tooth bar all is meshed with gear shaft, on the cylinder barrel sidewall between two rotary piston tooth bars, is provided with inlet hole.
In industries such as manufacturing, services, used flowing medium-air, water, steam etc. in large quantities and gone to carry out work such as powered, material are mixed and stirred, article cleaning.And the integrated control of these needs of work; With reach regularly, quantitatively, the action of fixed cycle, this product is developed for accomplishing these work exactly, this product is for adapting to the industrial valve type final controlling element that automation is made; Be compressibility characteristics according to gas; Pressurized air produces pressure air, produces power.Discharging air is eliminated pressure air, thereby forms the cycle period motion of a pressurization, decompression, realizes the supply in the industrial manufacture process, the production process of blocking-up.
It is power source that this product adopts air, and air has superior condition such as take conveniently, pollution-free, and this is for this product is applied to make widely, the service field provides convenience.
Description of drawings
Fig. 1 is the ball-valve structure schematic representation.
Fig. 2 is an A-A sectional drawing among Fig. 1.
Embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 1, be the ball-valve structure schematic representation, Fig. 2 is an A-A sectional drawing among Fig. 1.Described ball valve is made up of valve body 2, end cap 3, ball valve core 4, cylinder barrel 5, plastic end cover 6, spring 7, rotary piston tooth bar 8 and gear shaft 9.
The right ends of valve body 2 all is provided with end cap 3; The upside of valve body 2 connects cylinder barrel 5, and valve body 2 middle parts are provided with ball valve core 4, and ball valve core 4 is connected at the gear shaft 9 at cylinder barrel 5 middle parts; The right ends of cylinder barrel 5 all is provided with plastic end cover 6; Plastic end cover 6 connects a rotary piston tooth bar 8 through spring 7 respectively, and rotary piston tooth bar 8 all is meshed with gear shaft 9, on 5 sidewalls of the cylinder barrel between two rotary piston tooth bars 8, is provided with inlet hole 10.Valve body 2, ball valve core 4 are processed by the high-quality stainless steel, and cylinder barrel 5 is processed by aluminum alloy finish draw pipe.
This product adopts the bi-bit bi-pass form, be divided into normally closed, often open two kinds.When equipment control cabinet sends signal, the pilot pressure source of the gas gets between 2 rotary piston tooth bars 8 from inlet hole 10,9 rotations of rotary piston tooth bar 8 driven gear axles, and gear shaft 9 drives 4 rotations of ball valve cores; Valve opening, medium fluid begins conveyance fluid, treats that FLUID TRANSPORTATION finishes, and control cabinet sends signal once more; Blocking-up pilot pressure source of the gas makes gas flow out from inlet hole 10,9 revolutions of rotary piston tooth bar 8 driven gear axles; Valve closing, medium fluid is blocked, and stops to flow.
Between valve body 2 and end cap 3, valve seal pad 11 is housed, valve seal pad 11 usefulness are high temperature resistant, corrosion resistant Teflon is made, and between cylinder barrel 5 and gear shaft 9, Sealing 12 are housed, the product of Sealing 12 usefulness import Parker companies.
