Abstract
The utility model relates to the improvement of a pulp valve, which comprises a valve body and a hand wheel. The utility model is characterized in that the inside of the valve body is provided with a valve seat which can be tightly sealed by a sluice plate, and the sluice plate is connected with a sluice plate seat via a connecting body with a tension spring; a wedge block which is connected with the hand wheel via a screw rod is positioned between the sluice plate and the sluice seat; the sluice plate, the wedge block, and the sluice plate seat can form a wedge block mechanism which can push the sluice plate towards the valve seat; the upper part of the sluice plate seat is provided with a stop position which can prevent the relative movement of the sluice plate seat and the wedge block. The utility model has the advantages of labor saving in operation, good anti-abrasion performance and sealing performance, so the service life is long.
Description
The utility model relates to a kind of improvement of slurry valve door.
In the industrial production such as the ash trench system in thermal power plant and chemical industry, papermaking, mine, slag slurry (mortar, sewage etc.) valve makes valve wearing and tearing and leakage current easily owing to resistance to wear and poor sealing performance.For example the flashboard of gate valve, gate slot very easily are worn, and produce serious leakage current.In addition, the lock groove is stopped up by lime-ash, and flashboard can not cut out and put in place, is difficult to fit with valve seat, can't dam.
The purpose of this utility model provides a kind of Slag pulp sluice valve, its abrasion resistance and good airproof performance, thereby long service life.
The utility model comprises valve body and handwheel, difference is to be provided with the valve seat that can be shut by flashboard in the valve body, flashboard is linked by the connected body and the flashboard seat of band extension spring, the voussoir that links by screw rod and handwheel is between flashboard and flashboard seat, and flashboard, voussoir and the common formation of flashboard seat can be pushed flashboard to the cotter mechanism of valve seat, and flashboard seat top is provided with the backstop position that can stop with the relative movement of voussoir.
It is described to press such scheme, at the valve seat of valve interior wall to being provided with the streamline transitional surface between the valve outlet.
When this gate valve is closed, make flashboard and flashboard seat drop to the valve body bottom earlier, be rotated further handwheel, voussoir is pressed down, make voussoir produce horizontal thrust, make it to fit tightly better tightness with valve base chamber flashboard.During unlatching, rotate handwheel pulling voussoir and move upward, by the effect of backstop position, voussoir drives the flashboard seat and flashboard moves upward subsequently.With the flashboard panel seat of operating a switch, make it and valve seat be in the disengaging configuration by extension spring, therefore make it when motion, not have friction, handle laborsaving.As establish the streamline transitional surface in valve body, fluid flow state does not have obvious change, thereby makes flow resistance little, has alleviated cavitation and erosive wear.
Fig. 1 is the utility model plan view.
Fig. 2 is Figure 1A-A sectional view.
The utility model comprises valve body 7 and handwheel 6, establishes valve seat 1 in the valve body, and flashboard 2 is linked with flashboard seat 4 by the connected body 5 that has extension spring, and voussoir 3 links between flashboard and flashboard seat and with handwheel.Block 8 is set on the flashboard seat constitutes the backstop positions, can stop and voussoir between relative movement.Valve interior wall by valve seat to the outlet part be provided with the streamline transitional surface.
Claims (2)
1, a kind of applied force compensation sealing Slag pulp sluice valve, comprise valve body and handwheel, it is characterized in that being provided with in the valve body valve seat that can shut by flashboard, flashboard is linked by the connected body and the flashboard seat of band extension spring, the voussoir that links by screw rod and handwheel is between flashboard and flashboard seat, and flashboard, voussoir and the common formation of flashboard seat can be pushed flashboard to the cotter mechanism of valve seat, and flashboard seat top is provided with the backstop position that can stop with the relative movement of voussoir.
2, applied force compensation sealing Slag pulp sluice valve according to claim 1 is characterized in that valve seat at valve interior wall is to being provided with the streamline transitional surface between the valve outlet.
