Abstract
The utility model provides a novel butterfly valve, which is composed of a handle (1), a flange disc (2), a valve rod (3), upper ears (4), a valve body (5), a rear cover (6), lower ears (7) and the like. Being cast by cast iron, the previous butterfly valve has the disadvantages that the previous butterfly valve is heavy and not friendly to environment, the manufacturing process is complicated, the mould manufacturing is needed, the manufacturing cost is high, the aesthetic degree is low, and the installation and maintenance are inconvenient. The novel butterfly valve is characterized in that: a tooth disc which is used before is cancelled and is replaced with a pin hole, and a flow fraction plate is arranged at the top part; a spring, a safety pin and a fixed pin are arranged on the handle, and the safety pin on the handle is matched with the flow fraction plate. The valve body is made from seamless steel pipes, the handle is formed by the stamping of plates in one time, the ears and the rear cover are all formed by the stamping of plates in one time, and the valve entirely adopts the processing of electrostatic painting technique. The novel butterfly valve has the advantages of energy saving, environmental protection, simple structure, high durability, beautiful appearance and convenient installation as well as maintenance.
Description
Technical field
The utility model relates to a kind of butterfly valve, particularly a kind of novel butterfly valve.
Background technique
At present, the butterfly valve of manufacturing is mainly cast in the mode of cast iron under the prior art, such butterfly valve major defect be weight greatly, not environmental protection, manufacturing process complexity, need the mould manufacturing, problems such as manufacture cost is big, aesthetics is poor, installation and maintenance inconvenience.
Summary of the invention
The utility model provides a kind of energy-saving and environmental protection, simple in structure, durable, appearance looks elegant at above problem, and installation and maintenance are novel valve easily.
Solution of the present utility model is:
The utility model is made up of handle (1), flange plate (2), valve rod (3), last ears (4), valve body (5), bonnet (6), following ears (7) etc.; The characteristics of this butterfly valve are that valve body is made by seamless steel pipe.Handle is by the plate stamping single forming, used fluted disc before abolishing, use the pin-and-hole design to replace fluted disc in the past, like this can locking more convenient, more accurate, the top is provided with flow mark plate, handle, handle and is provided with spring, arming pin, fixing pin, cooperate by arming pin on the handle and flow mark plate,, reach the purpose of accurate control flow rate with the flow of control butterfly valve.Ears and bonnet all are by the plate stamping single forming, using the argon arc welding welding to make soldering opening smooth smooth attractive in appearance being connected of ears and valve body, have strengthened the connection dynamics again.Valve stem casing is made the valve body welding of also using argon arc welding method and valve by seamless steel pipe, and the integral body of valve uses electrostatic painting process to handle, and to reach energy-saving and environmental protection, simple in structure, durable, appearance looks elegant, installation and maintenance are purpose easily.
