Abstract
A flat plate sluice valve relates to valve technology field and is one of the commonest valves used in chemical, metallurgy and electric power industries. The valve is mainly composed of pressure flange, packing material, sealing ring, middle flange, valve stem, valve body, valve plate, limiter block, valve base and sealing ring, the valve plate is fixed on the lower end of valve stem and then placed into valve body, the middle flange is fixed in valve stem, the middle flange and valve body are connected by bolt. The sealing ring and sealing filler are adopted to double sealing for valve stem, that is to fill the sealing ring and sealing filler between center hole of middle flange and valve stem and then pressed by pressure flange. The valve base adopt movable mode to be installed in valve body and the sealing of valve base is double sealing, that is make the sealing rings on contact ends of valve base and valve plate. The limiter block is welded on valve body as guidance action for valve plate. The utility model has advantageous results as simple structure, reliable sealing, convenient maintenance and long performance life.
Description
One, technical field:
The utility model relates to valve technology field, particularly a kind of plate valve.
Two, background technique:
Plate valve is one of valve of generally using of industries such as chemical industry, metallurgy and electric power.Traditional construction of parallel gate valve is: valve stem seal is packing seal; Valve base sealing is a plane sealing; Valve seat is fixed, and promptly valve seat and valve body are overall structure.Because the sealing position is single sealing configuration, thereby the poor reliability of sealing; It is fixing adding upper valve base, behind the valve base sealing surface wear, and maintenance difficult, therefore, the bulk life time of valve is short.
Three, summary of the invention:
For solve classic flat-plate gate valve rod sealing be single packing seal, valve base sealing be that plane sealing, valve seat and valve body are that the sealing that brings of overall structure is unreliable, technical problems such as maintenance difficult and whole service life are short, the utility model provides a kind of novel flat-plate gate valve, the technological scheme that is adopted is: this valve mainly is made of differential, stuffing box packing, seal ring, middle flange, valve rod, valve body, valve plate, limiting stopper, valve seat and seal ring, and the valve rod lower end is equipped with valve plate and is contained in the valve body.Middle flange is housed on the valve rod, and middle flange is connected by bolt with valve body.Valve stem seal adopts seal ring and stuffing box packing double seal, seal ring and stuffing box packing promptly is housed between middle flange center hole and valve rod, and is compressed by differential.Valve seat adopts movable being contained in the valve body, is convenient to mounting or dismounting maintenance and replacing.Valve base sealing adopts plane and seal ring double seal, promptly at valve seat and valve plate contact jaw seal ring is housed.Also be welded with limiting stopper on the valve body, valve plate is play the guiding role.The beneficial effects of the utility model are simple in structure, and sealing is reliable, and easy to maintenance, whole service life is long.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the A-A partial sectional view of Fig. 1.
Five, embodiment:
Below in conjunction with accompanying drawing, set forth a preferred embodiment of the present utility model again.Referring to Fig. 1, Fig. 2 as can be known, the utility model mainly is made of differential 1, stuffing box packing 2, seal ring 3, middle flange 4, valve rod 5, valve body 6, valve plate 7, limiting stopper 8, valve seat 9 and seal ring 10, and valve rod 5 lower ends are equipped with valve plate 7 and are contained in the valve body 6.Flange 4 in being equipped with on the valve rod 5, middle flange 4 and valve body 6 are connected by bolt.Middle flange 4 center holes and 5 of valve rods are equipped with seal ring 3 and stuffing box packing 2, and are compressed by differential 1.Valve seat 9 is contained in the valve body 6, and valve seat 9 is equipped with seal ring 10 with the contact jaw of valve plate 7.Also be welded with the limiting stopper 8 that valve plate 7 is play the guiding role on the valve body 6.
