Description
Technical field
The utility model belongs to valve field, especially a kind of handle butterfly valve.
Background technique
Butterfly valve is that valve application is relatively extensive a kind of, currently, the basic structure of butterfly valve is all in valve body inner seat, valve body
Upper radially installed valve rod installs valve plate on the intracorporal valve rod of valve, and valve rod drives valve plate rotation, to open and close the stream in valve seat
Road.Handle valve is manual hand manipulation in use, and the size of switch fully relies on the experience of operator, compares and is difficult to accurately
Judge the flow control of valve in pipeline.
Utility model content
The purpose of the utility model is to overcome in place of the deficiencies in the prior art, provide a kind of design rationally, structure it is simple,
Handle butterfly valve easy to operate, with long service life.
The utility model solves its technical problem and adopts the following technical solutions to achieve:
A kind of handle butterfly valve, including valve body, valve plate, valve seat, valve rod and handle, are formed with the stream of lateral direction penetrating in valve body
Body channel is formed with through-hole on the valve body of the corresponding valve body upper end in portion in the fluid passage, and valve rod, valve rod lower end are installed in the through-hole
Fluid channel in valve plate is installed, the valve inner in valve plate two sides is separately installed with valve seat, and valve body is stretched out simultaneously in valve rod upper end
Handle is installed, it is characterised in that: it is that the stem outer circumference of handle, at its lower end is set with a ratchet, which is fixed on valve body,
An axle sleeve is installed outside valve rod, a pawl is hinged on axle sleeve, the pawl and the ratchet of ratchet inner circumferential are unidirectionally slidably matched, handle
When driving axle sleeve rotation, pawl often turns over a teeth.
Moreover, the ratchet inner circumferential is formed with the ratchet of ten bisections.
Moreover, the ratchet upper end below handle is fixed with a dial, which is formed with circumferential scale.
The advantages and positive effects of the utility model are as follows:
The utility model is equipped with ratchet mechanism in handle position, by the swing of pawl in rotation, prompts operator's valve
The opening degree of door, convenient for accurate control, structure is simple, and leakproofness is strong, and structure is simple, and the installation of valve part is simple,
Long service life.
Detailed description of the invention
Fig. 1 is the structural front view of the utility model；
Fig. 2 is A-A in Fig. 1 to profile.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing and by specific embodiment, and following embodiment is only retouched
The property stated, it is not restrictive, protection scope of this utility model cannot be limited by this.
A kind of handle butterfly valve, including valve body 4, valve plate 6, valve seat 5, valve rod 8 and handle 1 are formed in valve body and laterally pass through
Logical fluid channel is formed with through-hole on the valve body of the corresponding valve body upper end in portion in the fluid passage, and valve rod, valve are installed in the through-hole
Valve plate is installed in the fluid channel of bar lower end, the valve inner in valve plate two sides is separately installed with valve seat, and valve seat is matched with valve plate
Conjunction can seal fluid channel；
Valve rod upper end stretches out valve body and is simultaneously equipped with handle, control handle can driving stem rotation, so that valve plate be driven to turn
It is dynamic to open or close valve；
It is that 8 periphery of valve rod of handle, at its lower end is set with a ratchet 3, which is fixed on to promote valve plate flow control
On valve body, ratchet inner circumferential is formed with the ratchet of ten bisections；One axle sleeve 7 is installed outside valve rod, a pawl 9 is hinged on axle sleeve,
The pawl and the ratchet of ratchet inner circumferential are unidirectionally slidably matched, and when handle drives axle sleeve rotation, pawl often turns over a teeth, automatically
Springing is embedded in ratchet, consequently facilitating operator accurately controls the opening degree of valve.
In order to which further convenient for observation flow control, the ratchet upper end below handle is fixed with a dial 2, the scale
Disk upper end is formed with circumferential scale, can intuitively observe handle rotation angle.
Although disclosing the embodiments of the present invention and attached drawing for the purpose of illustration, those skilled in the art can be with
Understand: departing from the utility model and spirit and scope of the appended claims, various substitutions, changes and modifications are all can
Can, therefore, the scope of the utility model is not limited to the embodiment and attached drawing disclosure of that.
