Abstract
The utility model discloses a valve plate with high strength, which comprises a valve rod. Two semi-circular valve clacks are fixedly connected with two sides of the valve rod, annular seal rings are arranged to surround the edges of the two semi-circular valve clacks, annular reinforcing ribs and strip-shaped reinforcing ribs are arranged on the upper surfaces of the two semi-circular valve clacks, and arc water-sealing ribs are arranged at the bottoms of the two semi-circular valve clacks. The valve plate with high strength is reasonable and compact in structure, the annular reinforcing ribs and the strip-shaped reinforcing ribs improve stress resistance of the surfaces of the valve clacks so as to enable the valve clacks not to break under impact of strong pressure and enable the valve clacks to have high strength. The arc water-sealing ribs arranged at the bottoms of the valve clacks improve seal performance of the valve plate so as to greatly prolong service life of a butterfly valve.
Description
Technical field
The utility model relates to the butterfly valve field, is specifically related to a kind of valve plate of high tenacity butterfly valve.
Background technique
When butterfly valve was in full open position, butterfly plate thickness was MEDIA FLOW unique resistance when valve body, therefore fall through the pressure that this valve produced very little, so have metering characteristics preferably.Butterfly valve has two kinds of seals style of sealing of bullet sealing and metal.Elastic packing valve, seal ring can be embedded on the valve body or be attached to the butterfly plate periphery.
Adopt the valve of metallic seal generally long, but be difficult to accomplish to seal fully than the life of valve of elastic packing.Metallic seal can adapt to higher operating temperature, and elastic packing then has the defective of the temperature limitation of receiving.
If require butterfly valve to use as flow control, main is size and the type of correctly selecting valve.The structural principle of butterfly valve especially is fit to make large-diameter butterfly valve.Butterfly valve not only is used widely on general industries such as oil, coal gas, chemical industry, water treatment, but also is applied to the cooling water system of cogeneration power plant.
The model utility content
The purpose of the utility model provides a kind of high tenacity valve plate, and the sealing that solves existing valve plate is not good, the problem of flap easy-rupturing.
The technological scheme of the utility model is following:
A kind of high tenacity valve plate; Include valve rod; The both sides of said valve rod are fixedly connected with two semicircle flaps; It is characterized in that: the edge around two semicircle flaps is provided with O-ring seal, and the surface of said two semicircle flaps is provided with ring stiffener and bar shaped stiffening rib, and the bottom of two semicircle flaps is provided with arc water shutoff muscle.
Described high tenacity valve plate is characterized in that: described two semicircle flaps are positioned at the fluid passage of valve body and cooperate with the inner wall sealing of valve body fluid passage.
The beneficial effect of the utility model:
The utility model is rational in infrastructure, compact, and ring stiffener and bar shaped stiffening rib have improved the anti-stress on flap surface, thereby make flap under the impact of strong pressure, can not produce fracture, and intensity is high; The arc water shutoff muscle that the flap bottom is provided with has improved the sealability of valve plate, has prolonged the working life of butterfly valve greatly.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1; A kind of high tenacity valve plate; Include valve rod 1, the both sides of valve rod 1 are fixedly connected with two semicircle flaps 2, and the edge that centers on two semicircle flaps 2 is provided with O-ring seal 3; The bottom that the surface of two semicircle flaps 2 is provided with ring stiffener 4 and 5, two semicircle flaps of bar shaped stiffening rib is provided with arc water shutoff muscle 6.
Further, two semicircle flaps 2 are positioned at the fluid passage of valve body and cooperate with the inner wall sealing of valve body fluid passage.
Claims (2)
1. high tenacity valve plate; Include valve rod; The both sides of said valve rod are fixedly connected with two semicircle flaps; It is characterized in that: the edge around two semicircle flaps is provided with O-ring seal, and the surface of said two semicircle flaps is provided with ring stiffener and bar shaped stiffening rib, and the bottom of two semicircle flaps is provided with arc water shutoff muscle.
