Abstract
The utility model discloses a diamond control valve, which comprises a left valve body and a right valve body which are mutually connected. A flashboard is connected between the left valve body and the right valve body; the flashboard is connected with a valve rod; the valve rod is connected with an electric actuator; a 'V'-shaped baffle plate is arranged inside the valve body on one side; an inverted 'V'-shaped notch corresponding to the 'V'-shaped baffle plate is arranged on the flashboard; and the baffle plate is attached with the flashboard. By arranging the inverted 'V'-shaped notch on the flashboard and arranging the 'V'-shaped notch baffle plate inside the valve body, gradually changing opening is formed by the inverted 'V'-shaped notch of the flashboard and a 'V'-shaped notch of the baffle plate of the valve body, and the valve realizes gradual change of opening degrees along with ascending and descending of the flashboard. Compared with a butterfly valve, the diamond control valve has the advantages that an angle control opening is changed into a linear stroke control opening, a complicated functional relation is converted into a linear relation, control precision is greatly increased, and the conditions of small opening and small flow have little effect on control precision.
Description
Technical field
The utility model belongs to pipeline valve, is specifically related to a kind of knife plate gate valve.
Background technique
Need in the system of accurate control flow rate in sewage disposal system and other at present, great majority adopt butterfly valve as flow control valve, but butterfly valve is by the open degree control flow rate, there is the control accuracy problem, particularly under the small flow situation, simultaneously under little aperture situation, cause turbulent flow, make the feedback signal instability cause final controlling element frequent movement and then generation fault.
Summary of the invention
The purpose of this utility model is to provide a kind of control accuracy height, angle is controlled the rhombus control valve that aperture changes rectilinear path control aperture into, to address the above problem.
The technical solution of the utility model is: the rhombus control valve, and it comprises interconnective left valve barrel and right valve barrel, connects flashboard between the valve body of the left and right sides, and flashboard connects valve rod, and valve rod is connected with electric actuator; Be provided with " V " type baffle plate in the one side valve body, offer on the flashboard and corresponding " V " type breach of " V " type baffle plate, baffle plate and flashboard fit.
The utility model is provided with the v-notch baffle plate by reverse V-shaped breach and valve body are set on flashboard, the reverse V-shaped breach of flashboard and the v-notch of valve body baffle plate form the aperture gradual change, and along with flashboard rises or descends, valve is realized the gradual change of the size of open degree.It is compared with butterfly valve, and its advantage is: angle is controlled aperture change rectilinear path control aperture into, make the complicated function relation be converted to linear relationship, control accuracy is improved greatly, and under little aperture and the small flow situation, very little to the control accuracy influence.

Fig. 2 rhombus control valve structure cross-sectional schematic.
Fig. 3 valve body and flashboard sealed structural representation.
Embodiment
As shown in Figure 1, the valve body of rhombus control valve connects and composes (shown in Figure 2) by left valve barrel 1 and right valve barrel 2; Connect flashboard 3 between the valve body of the left and right sides, flashboard 3 connects valve rod 4, and valve rod 4 is connected with electric actuator 5.(on the valve body of water inlet flow channel end) is provided with " V " type baffle plate 6, V on the left valve barrel 1 " type baffle plate and left side valve body be overall structure (as shown in Figure 2).Offer on the flashboard 3 and corresponding " V " type breach 7 of " V " type baffle plate; " V " type breach that falls be complete demonstration in the drawings, among Fig. 1 up and down two fall " V " dotted line and represent under the different opening situation, the valve openings shape that flashboard 3 is formed between " V " type breach and " V " type baffle plate.
Be provided with seal arrangement between opposite side valve body and the flashboard.Right valve barrel 2 in the present embodiment
The seal groove of offering on (on the valve body of outlet flow end) 8 is provided with seal ring or seal ring in the seal groove 8, present embodiment adopts seal ring 9.
After electric actuator 5 actions of controlled signal, driving flashboards 3 by valve rod 4 does in valve body and moves up and down and can rest on any position in the stroke as required, the rhombus port area that forms of valve plate 3 and valve body increases or reduces or guarantee that certain circulation area is constant like this, accurately the control media flow.
