Description
Technical field
This utility model is related to electric butterfly valve technical field, specially a kind of full lining tetrafluoro electric butterfly valve.
Background technology
Development with electrically operated valve has a lot of esbablished corporations at present both at home and abroad, and present electric butterfly valve is got in actual applications
Come more extensive product wins numerous clients' favor with remarkable quality and perfect after-sales service in technology, connected mode is main
Have：Flange form and wafer type.It is the important performance element in field of industrial automation control.Belong to electrically operated valve and motorized adjustment
One of valve kind.It is widely used in weaving, power station, petrochemical industry, heating and refrigerating, pharmacy, shipbuilding, metallurgy, light industry, environmental protection etc.
Field.This product can be used as the stop valve of tubing, control valve and check-valves.Complete manual overvide, electronic or gas
Dynamic actuating device, can meet different operating mode actual conditionses.Meet most stringent of prescription, application that can be very lasting.
Particularly in iron and steel metallurgy, shipbuilding industry, there is very high popularity benefit prospect.
Electric butterfly valve is applicable to the occasion of Flow-rate adjustment.Because pressure loss ratio in pipeline for the butterfly valve is larger, greatly
Being approximately three times of gate valve, therefore when selecting butterfly valve, should taking into full account that pipe-line system is stressed the impact of loss, it is also contemplated that closing
When closing, butterfly plate bears the robustness of pipe medium pressure.In addition it is necessary to consider the born work of elastic seat material at high temperature
Make the restriction of temperature, existing electric butterfly valve opens and closes speed slowly, arduously, the resistance of convection cell is big, and poor sealing performance adjusts performance
Difference.
Utility model content
The purpose of this utility model is to provide a kind of full lining tetrafluoro electric butterfly valve, to solve to propose in above-mentioned background technology
Problem.
For achieving the above object, this utility model provides following technical scheme：A kind of full lining tetrafluoro electric butterfly valve, including on

Brief description
Fig. 1 is this utility model structural representation.
In figure：1 YE, 2 fixed supporting seats, 3 valve rods, 4 valve seats, 5 valve elements, 6 sealing rings, 7 lower valve bodies, 8 journal stirrups,
9 upper valve bodies, 10 support columns.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1, this utility model provides a kind of technical scheme：A kind of full lining tetrafluoro electric butterfly valve, including upper valve body
9, be provided with valve seat 4 below described upper valve body 9, the lower section of described valve seat 4 is provided with lower valve body 7, described valve seat 4 and upper valve body 9 and under
The contact surface of valve body 7 is provided with journal stirrup 8, and the top of described upper valve body 9 is provided with fixed supporting seat 2, is provided with described fixed supporting seat 2
Support column 10, the top of described fixed supporting seat 2 is provided with YE 1, is provided with valve rod 3, described valve rod 3 in described valve seat 4
Upper valve body 9 is run through in upper end and fixed supporting seat 2 extends on support column 10, and described valve rod 3 lower end extends in lower valve body 7, institute
The inner ring stating valve seat 4 is provided with sealing ring 6, and described valve rod 3 is provided with valve element 5, and valve element 5 is in the inside of valve seat 4, described valve element
5 and valve seat 4 flow cross-sectional area equal, the outer surface of described valve seat 4 is provided with corrosion-resistant coating, and the quantity of described journal stirrup 8 is 4
Individual, described journal stirrup 8 is symmetrical set with valve rod 3 for symmetrical centre.
Operation principle：It is controlled by using the break-make that YE 1 carrys out convection cell, when the horizontal stroke of valve element 5 and valve seat 4
During salty conjunction that section fluid is through-flow, fluid can not flow through this moment, when the through-flow mouth of cross section fluid of valve element 5 and valve seat 4 tilts,
Fluid can flow through this moment.Therefore we can control the rotational angle of valve rod 3 by YE 1, and then controls valve element 5
Inclined degree, thus controlling the size of fluid flow.
