Abstract
The utility model relates to an install swift metal butterfly valve sealed firmly, including the turbine head, a valve body, valve rod and butterfly plate, the coaxial valve neck that passes valve body upper portion of valve rod, rotate and sealing connection between valve stem end and the valve body, turbine head power take off end is connected to the valve rod upper end, the butterfly plate is established in the valve body, valve rod and butterfly plate fixed connection, valve neck tip system on valve body upper portion has radial fixed station, the marginal double -phase offside axial of fixed station is upwards extended an organic whole and is made and prolong the pole, prolong pole upper end tip on two and make flange connection plate with the coaxial an organic whole of neck end, fixed turbine head is connected on this flange connection plate upper portion. The application provides a during install swift metal butterfly valve sealed firmly installation turbine head direct on the support on flange upper portion can, the quantity of screw has been saved to the process of having saved twice screwed connection, saves the cost.
Description
Technical field
The utility model belongs to valve field, is a kind of metal hard-sealing butterfly valve quick for installation.
Background technique
Hard seal butterfly valve is Flap valve again, is the simple modulating valve of a kind of structure, also can be used for the switch control rule of low pressure pipeline medium simultaneously.Hard seal butterfly valve main rising on pipeline is cut off and throttling action.Butterfly valve open-shut device is a discoidal butterfly plate, rotates in valve body around the axis of himself, thus reaches the object opening and closing or regulate.Hard seal butterfly valve is applicable to carry on the pipeline of various corrosivity, non-corrosive fluids medium, for regulating and block the flowing of medium in producer, coal gas, steam, rock gas, town gas, air, chemical industry smelting engineering and generation environment-friendly system.Hard seal butterfly valve can be divided into manual hard seal butterfly valve, pneumatic hard seal butterfly valve, electronic hard seal butterfly valve.
The turbine head of existing metal hard-sealing butterfly valve is arranged on valve body upper end portion by a turbine headstock, is arranged on valve body by driving mechanism support by driving mechanism, and install very time-consuming, meanwhile, the weight of valve body own is larger.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of structure simple, convenient, that valve body is light metal hard-sealing butterfly valve quick for installation is installed.
The technological scheme that the utility model realizes object is as follows:
A kind of metal hard-sealing butterfly valve quick for installation, comprise turbine head, valve body, valve rod and butterfly plate, valve rod is coaxially through the valve neck on valve body top, rotate between valve stem end and valve body and be tightly connected, valve rod upper end connects turbine head clutch end, butterfly plate is located in valve body, valve rod is fixedly connected with butterfly plate, radial stationary platen is integrally shaped with in the valve neck end on valve body top, fixing edge of table two opposite sides axially upwards extend to be made into integration prolongs bar, end, bar upper end is prolonged and neck end coaxially integrally makes Flange joint dish on two, this Flange joint dish top is connected and fixed turbine head.
The beneficial effects of the utility model are:
1, a scaffold is integrally made in the flange upper end of the valve body of metal hard-sealing butterfly valve quick for installation that the application provides, this scaffold directly installs turbine head drive unit, do not need additionally to be connected by a link press span, structure is simple, reduces the height of whole valve body again.
2, when the metal hard-sealing butterfly valve quick for installation that the application provides installs turbine head directly on the support on flange top, save the process that twice screw connects, save the consumption of screw, saving cost.
3, the metal hard-sealing butterfly valve quick for installation that the application provides decreases link press span, and by calculating, the weight entirety of valve body alleviates about 10%, saves cost of production and cost of transportation, reduces labor strength.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model;
Fig. 2 is the right elevation of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of metal hard-sealing butterfly valve quick for installation, comprise turbine head 1, valve body 7, valve rod 2 and butterfly plate 8, valve rod is coaxially through the valve neck 6 on valve body top, rotate between valve stem end and valve body and be tightly connected, valve rod upper end connects turbine head clutch end, butterfly plate is located in valve body, and valve rod is fixedly connected with butterfly plate.The innovation of the application is:
Radial stationary platen 5 is integrally shaped with in the valve neck end on valve body top, this stationary platen is used for fixing and seals the valve rod going deep into valve body, fixing edge of table two opposite sides axially upwards extend to be made into integration prolongs bar 4, prolong end, bar upper end on two and neck end coaxially integrally makes Flange joint dish 3, this Flange joint dish top is connected and fixed turbine head.
The application changes the turbine head mounting type of existing metal hard-sealing butterfly valve, and the mode taking single step to install turbine head has been come, and saves a large amount of man power and materials.
