Abstract
Disclosed is a comb tooth type regulating butterfly valve for regulating medium parameters in a water supply and sewage pipeline with a large caliber. The utility model is improved on the structural form of a butterfly plate for technical reconstruction on the basis of a valve which is composed of a valve body, a transmission mechanism, and an electric device. The utility model is characterized in that the upstream side of the right side of the butterfly plate is provided with comb teeth, and the downstream side of the reverse side is provide with a rectangular through hole for preventing cavitation and rectification. The utility model which has the advantages of stable flow state, cavitation prevention, noise reduction, stable work of the butterfly plate, and no vibration of the butterfly plate when flow capacity is controlled can be applied to a place for adjusting fluid parameters.
Description
The utility model relate to a kind of in heavy caliber pipeline system the valve of control media flow and pressure and other parameters, particularly need regulate the valve that uses under the fed sheet of a media parameter place in industries such as water factory, power plant, chemical industry.
At present, the control media flow parameter is selected the common butterfly valve control flow rate of being made up of valve body and board-like butterfly plate for use on the heavy caliber pipeline.Normal in the work fluid easily sprays because of board-like butterfly plate is little to the flowing medium resistance, thereby causes the butterfly plate judder and produce cavitation erosion.Simultaneously, adjusting function is poor, is difficult to satisfy the operating mode needs.
The purpose of this utility model provides and a kind ofly prevents to cavitate, improve fluidised form, reduces noise, butterfly plate stable working, volume is little, easy for installation, cost is low comb-shaped are regulated butterfly valve.
The purpose of this utility model is achieved in that
Promptly on the basis of existing butterfly valve, in valve body (1) by pin (A, B) in last lower valve shaft (6,2) between, fix the comb-shaped butterfly plate (3) of a carding tooth surface to the fluid input direction, this butterfly plate is by on the broach butterfly plate seat (10) that is shaped on the logical hole (H) of rectangle overleaf, by comb floor plate set screw (C), in this less than 180 ° plane on, fixing one one end has being the spherical end surface of radius of curvature less than valve channel radius (SR), the other end is by having 15 ° to the inclined-plane of 45 ° of angle of tilt and the comb floor plate (9) of three kinds of dissimilar tooth forms that constitute, tooth (G on the comb floor plate (9), F, E) to disperse the current and the flow direction in order reaching, to prevent cavitation erosion, reduce noise and the vibration of reduction butterfly plate and be designed to ruler shape and curved chi shape.Wherein tooth (G) is a ruler shape, and tooth (F, E) is curved chi shape, and the bent angle E group of curved chi shape is the α angle, and the F group is the β angle, and the α angle is 100 ° to 150 °, and the β angle is 130 ° to 170 °.It is also by seal ring set screw (D) and seal ring pressing plate (4), the seal ring (5) that to fix a cross section on broach butterfly plate seat (10) be T shape.
Because comb-shaped butterfly plate (3) is made up of broach butterfly plate seat (10), comb floor plate (9), seal ring pressing plate (4) and seal ring several detachable mechanical parts such as (5), therefore, this valve highly versatile.It not only can be used as modulating valve, and can be used as the stop valve use, and when the valve complete shut-down, because the effect of seal ring (5), its medium Leckage is zero.
An embodiment in reference to the accompanying drawings further explains below:
Fig. 1 regulates the butterfly valve structure schematic representation for comb-shaped.
1 is valve body among the figure, and 2 is lower valve shaft, and 3 is the comb-shaped butterfly plate, and 4 is the seal ring pressing plate, and 5 is seal ring, and 6 is last valve shaft, and 7 is driving mechanism, and 8 is Electric actuator, and A, B are pin, and H is the logical hole of rectangle.
Fig. 2 is a comb-shaped butterfly plate structural representation.
SR is the radius of curvature of increment face among the figure.
Fig. 3 is a comb-shaped butterfly plate schematic top plan view.
E, F, G are tooth among the figure, and α, β are bent angle, and C is the comb floor plate set screw, and D is the seal ring set screw.
When the utility model uses in pipeline, by the Mechanical ﹠ Electrical Transmission relation of Electric actuator, driving mechanism and valve shaft, will regulate the parameter of medium as required, control comb-shaped butterfly plate rotates.Because the structural feature of this butterfly plate, promptly the upstream side of plate is provided with tooth, and the downstream side is provided with the logical hole of rectangle, improves the flowing state of medium so greatly and prevents producing cavitation erosion, thereby realized purpose of the present invention.
The utility model compared with prior art has following advantage (namely because the utility model adopts the version of broach formula butterfly plate, so in use produce following effect):
1, comb water guide stream improves fluidised form;
2, prevent cavitation erosion and eddy current phenomenon;
3, transfer levelling sliding, control flow precision height;
4, reduce butterfly plate vibration and noise.
Claims (2)
1, a kind of comb-shaped of being made up of valve body (1), last lower valve shaft (6,2), driving mechanism (7) and Electric actuator (8) is regulated butterfly valve, it is characterized in that in the valve body by pin (A, B), between last lower valve shaft (6,2), fix the comb-shaped butterfly plate (3) of a carding tooth surface to the fluid input direction.
2, comb-shaped according to claim 1 is regulated butterfly valve, it is characterized in that said comb-shaped butterfly plate (3), it is by on the broach butterfly plate seat (10) that is shaped on the logical hole (H) of rectangle overleaf, by comb floor plate set screw (C), in this less than 180 ° plane on, fixing one one end has being the spherical end surface of radius of curvature less than valve channel radius (SR), the other end is by having 15 ° to the inclined-plane of 45 ° of angle of tilt and the comb floor plate (9) of three kinds of dissimilar tooth forms that constitute, this tooth (G) is a ruler shape, (F, E) be curved chi shape, the bent angle E group of curved chi shape is the α angle, the F group is the β angle, the α angle is 100 ° to 150 °, and the β angle is 130 ° to 170 °; By seal ring set screw (D) and seal ring pressing plate (4), the seal ring (5) that to fix a cross section on broach butterfly plate seat (10) be T shape.
