Specific implementation mode
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
As shown in figs. 1 to 6, in this present embodiment, a kind of triple valve described in the utility model, including valve body 1, baffle 9
And there is supervisor's connector 4, first to be in charge of connector 2 and second be in charge of connector 3, the supervisor for driving part 5, the valve body 1
Connector 4 and described first is in charge of between connector 2 and has the first obtuse angle alpha, the supervisor connector 4 and described second be in charge of connector 3 it
Between form the second obtuse angles beta, the baffle 9 is arranged inside the valve body 1, and the driving part 5 is connect with the baffle 9, use
In driving described in 9 selective shut-off of baffle first to be in charge of connector 2 or described second be in charge of connector 3.
In the prior art, supervisor's connector 4 of triple valve and the angle being in charge of between connector are generally 90 °, due to being responsible for
Connector 4 and the curvature being in charge of between connector are larger, and gas flows into valve body 1 by that can cause when being in charge of connector by supervisor's connector 4
Change dramatically occurs for the speed of air-flow and flow direction, increases the resistance of gas, is being in charge of connector and 1 angular position of valve body
Inner wall by larger gas shock power, reinforce the corrosiveness to being in charge of connector and the inner wall of the angular position of valve body 1, together
When also increase the energy loss of air-flow.First obtuse angle alpha is set, make supervisor's connector 4 and first be in charge of connector 2 between angle be more than
90 °, the curvature for slowing down supervisor's connector 4 and being in charge of between connector；Second obtuse angles beta is set, supervisor's connector 4 is made to be in charge of with second
Angle between connector 3 is more than 90 °, the curvature for also slowing down supervisor's connector 4 and being in charge of between connector.By this design, divide
Supervisor's connector 4 and first is not increased to be in charge of connector 2 and second be in charge of angle between connector 3, is reduced gas and is connect from supervisor
First 4, which enter first, is in charge of connector 2 or the second and is in charge of 3 turn degree of connector, and then weakens gas pair first and be in charge of connector 2 and the
Two are in charge of the impact force of connector 3, final to realize the inner wall for being in charge of connector and the angular position of valve body 1 reduced to the triple valve
The purpose of corrosion, extends the service life of the triple valve, while decreasing the loss of gas energy.Pass through driving part
5 driving baffle 9 selective shut-ofves first are in charge of connector 2 and second are in charge of connector 3, to the gas in pipeline 8 carry out cut-out or
It exchanges.When baffle 9 and first be in charge of connector 2 and block when, supervisor's connector 4 is in charge of connector 3 with second and is connected to, and gas is in baffle 9
Blocking is lower to be stopped being in charge of connector 2 into first, and the gas of connector 2 is in charge of in cut-out first, and gas enters second point from supervisor's connector 4
Pipe fitting 3, by baffle 9 realize to first be in charge of connector 2 and second be in charge of connector 3 closure or openness synchronous control.When
