Abstract
The utility model provides a handle type butterfly valve, comprising a handle, a transmission shaft, a butterfly valve and a valve plate. The handle type butterfly valve is characterized in that the transmission shaft is vertically connected with the lower side of one end of the handle, the valve plate is arranged at the other end of the transmission shaft, the transmission shaft penetrates through the butterfly valve, and the valve plate is positioned in the butterfly valve. The handle type butterfly valve has the advantages that the operation is easy, the working efficiency is improved, the service life is long, the production cost is reduced, and the like.
Description
Technical field
The utility model belongs to valve technology field, especially relates to a kind of valve block of butterfly valve and the valve that transmission shaft is cast as one.
Background technique
Transmission shaft and valve are to flexibly connect in existing technology, butterfly valve exists because pressure and the long-time reason of using wearing and tearing, valve block can occur loosening or fracture with being connected of transmission shaft meeting, after long-time the use, swinging appears in the transmission shaft effect of can being stressed, thereby influence the sealing effect of valve, reduced the problems such as reliability of system.
Summary of the invention
Problem to be solved in the utility model provides the handle type flange butterfly that a kind of valve and transmission shaft are cast as one, and especially is fit to be suitable for and some sewage disposal devices, on the equipment such as boats and ships drainage system.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of handle type butterfly valve, it comprises handle, transmission shaft, butterfly valve, valve block, it is characterized in that: described transmission shaft is vertically connected at the end below of described handle, the other end of described transmission shaft is provided with described valve block, described transmission shaft passes described butterfly valve, and described valve block is positioned at described butterfly valve.
The utility model also relates to following technical characterstic:
On the described handle pressure switch is installed.
Described transmission shaft and described valve block are cast as one.
Described transmission shaft passes described butterfly valve.Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, and more convenient to operate; Have simple in structure, easy to maintenance, the advantages such as reliability that processing cost is low, improved system.
Description of drawings
Fig. 1 is structural representation of the present utility model
Among the figure:
