Abstract
The utility model relates to a hackle sludge valve, which mainly comprises a valve body, a gate plate arranged in the valve body, a screw rod connected with the upper end of the gate plate, a support bracket positioned on the upper portion of the valve body and a valve seat arranged on the valve body. The utility model is characterized in that the valve holes on the valve body adopt a gate plate slot as the boundary. The lower semicircle of the valve holes on one side is a teeth-shaped structure. The utility model has the advantages that the problem that the bottom portion of the valve body and the inner portion of the gate plate slot are easy to generate deposition is fundamentally solved in order to prolong the service life of the valve. Meanwhile, the problem of difficult change on the valve seat is also solved.
Description
The utility model relates to a kind of valve, relates to a kind of hackle sludge valve specifically.
The valve body of the screenings valve of prior art all is split-type structurals, promptly is made up of left and right sides two halves, and its valve opening is the smooth surface structure.When the valve of above-mentioned prior art uses, very easily produce alluvial in the bottom of valve body and the flashboard slot under the sewage environment, cause the flashboard bad sealing, when serious even valve base surface is torn, directly influenced the working life of valve.In addition, the valve of said structure is limit because of structure, when need are changed valve seat, valve body must be dismantled could change.
The purpose of this utility model provide with regard to being to overcome above-mentioned deficiency of the prior art a kind of can prevent from effectively to deposit when under the sewage environment, using can change a kind of hackle sludge valve of valve seat easily.
The purpose of this utility model can adopt following measure to realize:
Hackle sludge valve of the present utility model mainly comprises valve body, is installed in the flashboard in the valve body, with the leading screw that flashboard upper end links together, is positioned at the support on valve body top and the valve seat that is installed on the valve body is formed; Valve opening on the valve body is the boundary with the flashboard slot, and the lower semi-circle of its one side valve opening is a tooth-shape structure.
The addendum of the tooth-shape structure that processes on the utility model valve opening lower semi-circle is lower than the cylindrical that equals valve seat, and is concordant with the bottom land of flashboard slot at the bottom of its tooth; Its valve body is a monolithic construction in addition.Valve body is two halves formula structure also, combines by bolt.
Structure characteristic of the present utility model has fundamentally solved the bottom and the interior problem that easily produces alluvial of flashboard slot of valve body, thereby has prolonged the working life of valve greatly, has also solved the problem of replacing valve seat difficulty simultaneously.
The drawing of accompanying drawing is described as follows:
Fig. 1 is that master of the present utility model cuts open figure.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is the B-B sectional view of Fig. 1.
The utility model is done with detailed description below with reference to embodiment's (accompanying drawing):
As shown in the figure, hackle sludge valve of the present utility model, the valve body (1) that mainly comprises monolithic construction, be installed in the flashboard (2) in the valve body, with the leading screw (5) that links together on the flashboard, be positioned at the support (6) on valve body top and be installed in valve seat (3) on the valve body, and gland (4) forms, handwheel (7) is installed in the top of leading screw (5); Valve opening on the valve body is the boundary with the flashboard slot, and the lower semi-circle of its one side valve opening is a tooth-shape structure, and the addendum of the tooth-shape structure that processes on its valve opening lower semi-circle is lower than the cylindrical that equals valve seat, and is concordant with the bottom land of flashboard slot at the bottom of its tooth.Valve seat (3) can adopt following material: as rubber type of material, stainless steel, asbestos etc.
When valve of the present utility model is changed valve seat at needs, only flashboard upwards need be mentioned and to change valve seat easily.
Claims (2)
1, a kind of hackle sludge valve, it is by valve body (1), be installed in the flashboard (2) in the valve body, with the leading screw (5) that links together on the flashboard, the valve seat (3) that is positioned at the support (6) on valve body top and is installed on the valve body is formed, of the present utility model being characterised in that: the valve opening on the valve body (1) is the boundary with the flashboard slot, and the lower semi-circle of its one side valve opening is a tooth-shape structure.
2, hackle sludge valve according to claim 1 is characterized in that: addendum is lower than the cylindrical that equals valve seat, and is concordant with the bottom land of flashboard slot at the bottom of its tooth.
