Abstract
The invention discloses an environmentally-friendly valve body, which comprises a cavity formed by forming a valve body flow passage, among which the cavity contour of the valve body flow passage is a fan-shaped cavity formed by a valve flap about an axial center running track line and an inner boundary line commonly formed with a straight-through cylindrical cavity boundary. The invention relates to a valve body whose contour accords with the operation locus of the valve disc. The valve body can reduce the usage amount of the steel material, improve the utilization rate of the material, reduce the waste of iron ore, electric power, human resources and other resources, and protect the environment, but does not affect the valve function. The present invention is applicable to a swing check valve body rotating around a fixed shaft by a valve flap.
Description
Technical field
The invention belongs to technical field of valve manufacturing is and in particular to a kind of environment-friendly type valve body.
Background technology
In the design of valve produces, the weight of valve body substantially accounts for the 75% ~ 87% of gross weight.For ensureing valve body, valve gap
Deng pressure part security under high pressure, wall thickness is all thicker, containing very big corrosion, wear surplus.Meeting valve body pressure-bearing
And on the premise of processing and manufacturing, the weight reducing valve body by optimization design is very worth research.Such as check-valves, conventional type
Valve body is olive-type valve body (see figure 1), and weight is than larger.This is mainly its Internal periphery shape and the running orbit of flap is not assisted
Adjust, the fixing axle that the running orbit of flap is around in valve body is rotated, and the Internal periphery of valve body is around fluid center line
Revolution forms, and in order to meet the opening angle of flap, the small end of olive ball valve body will be made thin and could meet greatly opening of flap
Open angle.If axle center design is unreasonable, the radius of gyration of flap becomes big, and rotary space is just very big.The chamber of whole valve body is just
Become is very big, and this is the reason olive ball valve body is heavier.If a kind of valve body Internal periphery can be designed meet flap running orbit
Valve body it is possible to reduce the usage amount of steel, improve the utilization rate of material, reduce to iron ore, electric power, the resource such as manpower
Waste, environmental protection, benefit the society.
Content of the invention
The present invention provides a kind of environment-friendly type valve body, reaches the purpose of material-saving and then environmental protection.
The present invention adopts the technical scheme that:
A kind of environment-friendly type valve body, including the cavity forming valve flowing channel, the cavity profile of described valve flowing channel is flap around axle center
The inner edge boundary line that the fan-shaped cavity that running orbit line is formed is collectively forming with through type cylindrical cavity border.
The fan-shaped cavity that described flap is formed around axle center running orbit line consists of: in flap central motion trajectory being
Heart line, the fan-shaped cavity being formed for border with flap original position ak, final position mc, valve body inner outline, this fan-shaped cavity
Base formation overlay region with through type cylindrical cavity.
The present invention is the valve body that a kind of valve body Internal periphery meets flap running orbit, it is possible to reduce the usage amount of steel, carries
The utilization rate of high material, reduces to iron ore, electric power, the waste of the resource such as manpower, environmental protection.
The present invention is applied to the valve body of the swing check valve that the closure members such as flap are rotated around fixing axle.
Brief description
Fig. 1 is olive ball-type valve body cross-sectional schematic in prior art；
Fig. 2 is the cross-sectional schematic of the present invention；
Fig. 3 is the track schematic diagram of the present invention.
Specific embodiment
The present invention is described in detail below in conjunction with the accompanying drawings.
With reference to Fig. 2,3, a kind of environment-friendly type valve body, main include valve body 1, flap 2, rocking bar 3, bkl overlay region 5, axle center 6,
Flap central motion trajectory 7, valve body inner outline 8, loef region 9, makc region 10, dgbn region 11.
A kind of environment-friendly type valve body, including the cavity forming valve flowing channel, the cavity profile of described valve flowing channel be flap around
The inner edge that this fan-shaped cavity of makc region 10 that axle center 6 running orbit line is formed is collectively forming with through type cylindrical cavity border
Boundary line.Through type cylindrical cavity is collectively forming by two sections of through type cylinder dgbn regions 11 and loef region 9 cavity boundary.
The makc region 10 fan-shaped cavity composition that described flap is formed around axle center 6 running orbit line: with flap central motion
Line centered on trajectory 7, forms rotational circle annular space with flap original position ak, final position mc, valve body inner outline 8 for border
Chamber.
Described rotation fan-shaped cavity makc region 10 and three parts (loef region 9, part nblo in makc region 10,
Dgbn region 11) base of through type cylindrical cavity runner dgfe that forms forms bkl overlapping region 5.
Below, illustrate the present invention taking Fig. 3 as a example.
In Fig. 3, after valve flowing channel is merged by straight-through cylindrical cavity loef region 9, makc region 10, dgbn region 11
Internal periphery forms；Makc region 10 is that flap 2 is fanned around the rotation that axle center 6 rotates along flap central motion trajectory 7
Shape cavity, it is made up of original position ak of flap 2, final position mc and valve body inner outline 8.Valve body inner outline 8 and gf
The bkl overlay region 5 that line is formed is more much smaller than olive ball-type valve body shadow region ijc region 1 in Fig. 1, shows environment-friendly type valve body
Fluid passage similar with the steel pipe of straight channel, fluid resistance is very little, about 0.1.And the flow resistance system of olive ball-type valve body
Number is 1.3 ~ 2.5, and both differ 13 ~ 25 times it means that its pipeline pump of needing power very big of check-valves of olive ball-type carries
For conveying power.Can contrast from Fig. 1 and Fig. 3, the olive ball-type valve body of identical bore uniform pressure and environment-friendly type valve body,
The former volume is bigger than the latter, can learn, the valve weight of the latter is the former 55% ~ 70%, saves after measurement weight
Substantial amounts of material, and do not affect the pressure-bearing function of valve, reduce flow resistance.
