Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment 1: a kind of hydraulic station flow control valve, as depicted in figs. 1 and 2, including application valve body 1, two sets respectively
The connecting flange 2 at 1 both ends of application valve body is set, the both ends of application valve body 1 have been wholely set installing pipe 3 respectively, have leaned on connecting flange 2
One end of nearly application valve body 1 has been wholely set male-pipe 4.Being arranged in installing pipe 3 can be threaded connection on male-pipe 4
Connecting tube 5, the turning end 51 in regular polygon is formed on the side outer wall of connecting tube 5；Installing pipe 3 and connecting tube 5 it
Between be provided with the first seal assembly 6, the second seal assembly 7 is provided between male-pipe 4 and connecting tube 5.
As depicted in figs. 1 and 2, male end 31 is formed on the side outer wall of installing pipe 3.First seal assembly 6 includes
The end cap 61 being threaded in male end 31, the first sealing ring 62 for being set in installing pipe 3 and being embedded in end cap 61；
And when end cap 61 is located at male end 31 close to one end of application valve body 1, connecting tube 5 can be detached from installing pipe 3；First sealing ring
Be pushed against after 62 stress deformations between the inner wall three of the side outer wall of installing pipe 3, the end face of connecting tube 5, end cap 61 realize it is close
Envelope.Twice mounting groove 32 is offered on the side outer wall of 2 one end of connecting flange in installing pipe 3 simultaneously, mounting groove 32 is embedded
Entering has the third sealing ring 33 being pushed against on 5 inner wall of connecting tube.Simultaneously connecting tube 5 close to 1 one end of application valve body internal diameter along
It is arranged close to the direction of application valve body 1 in necking, and two third sealing rings 33 are in the part of necking setting with connecting tube 5 respectively
It offsets.
As depicted in figs. 1 and 2, the second seal assembly 7 is the second sealing ring 71 being set on male-pipe 4, and second is close
Connecting flange 2 is pushed against after 71 stress and deformation of seal between the end face of application valve body 1 and the end face of connecting tube 5.Exist simultaneously
Connecting flange 2 is on the end face of application valve body 1, connecting tube 5 is offered on the end face of connecting flange 2 for the second sealing
The limiting slot 8 that circle 71 is respectively embedded into.
Implementation principle: after mounting, connecting flange 2 is connected on external pipeline, passes through the installing pipe in application valve body 1
Connecting tube 5 is set between 3 and the male-pipe 4 of connecting flange 2, so that when connecting tube 5 is gradually reduced the screw thread with male-pipe 4
Contiguity is to when being detached from, and application valve body 1 and connecting flange 2 are separated at this time, thus it is easy to disassemble, it is convenient to application valve body 1
It is overhauled or is replaced in part；The first seal assembly 6 and the second seal assembly 7 are used to keep leakproofness when connecting simultaneously.
When the first sealing ring 62 in the first seal assembly 6 be pushed against the side outer wall of installing pipe 3, connecting tube 5 end face,
When between the inner wall three of end cap 61, there is good leakproofness between installing pipe 3 and connecting tube 5.
There are gaps when being connected through a screw thread between connecting tube 5 and male-pipe 4, by the way that the second sealing ring 71 is arranged, and
So that the second sealing ring 71 is pushed against connecting flange 2 between the end face of application valve body 1 and the end face of connecting tube 5, to increase
Leakproofness when connecting tube 5 and male-pipe 4 being added to connect.
Multiple third sealing rings 33 between installing pipe 3 and connecting tube 5, further increase installing pipe 3 and connecting tube 5
Between leakproofness；And because connecting tube 5 close to 1 one end of application valve body internal diameter along close to application valve body 1 direction be in necking
Setting, when so that the degree that connecting tube 5 and male-pipe 4 are threadedly coupled gradually increasing, connecting tube 5 squeezes third sealing ring 33
Dynamics gradually increases, and further increases leakproofness.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
