It is important to note that referring to shown in attached drawing 3 and attached drawing 4, input duct 22 provided in this embodiment and out liquid
Pipeline 23 is ripple pipeline in connection, i.e., is shaped form in the channel 265 that pipeline oil inside offering body passes through, when high pressure oil body is logical
Out-of-date, oil body can repeatedly touch the inner wall of pipeline, substantially reduce the pressure and flow velocity of oil body.Therefore, compared to traditional straight tube
Road, the ripple pipeline in the present embodiment have the characteristics that dual-seal, can reinforce the leakproofness of shut-off valve by ripple pipeline,
It effectively prevent shut-off valve to reveal, improves the quality of shut-off valve, solve the problems, such as that oil body is easy to be lost.
Further, input duct 22 and liquid outlet pipe 23 can be with the center symmetric settings of valve body 20.
Specifically, be provided on the inner wall of installing port it is first annular protrusion and the second annular protrusion, it is first annular protrusion and
The end of second annular protrusion extends towards the center position of valve chamber 21.
The stop zone placed for seal assembly 50 is formed between first annular protrusion and the second annular protrusion, it is first annular
Protrusion and the second annular protrusion are mobile relative to valve body 20 for limiting seal assembly 50.
It should be noted that be provided with limiting section at the installing port of valve chamber 21 provided in this embodiment, which can be with
Including first annular protrusion and the second annular protrusion, first annular protrusion and the second annular protrusion can be on the inner walls of installing port
It is setting up and down along the vertical direction, it can be arranged above the second annular protrusion for first annular protrusion, be spaced one between the two
Seal assembly 50 is arranged inside the stop zone with forming stop zone for fixed distance.
It, can band during valve rod 30 moves up and down when being that setting is connected on valve rod 30 due to seal assembly 50
Dynamic sealing assembly 50 is mobile simultaneously, if seal assembly 50 is being slided in moving process and is being detached between valve rod 30 and installing port
Position then loses to the sealing effect between valve rod 30 and installing port, therefore does not solve the problem, the present embodiment setting limit
Region.When valve rod 30 is moved up with dynamic sealing assembly 50, the upper surface of seal assembly 50 can be connected to first annular protrusion
Side wall on, or when valve rod 30 is moved down with dynamic sealing assembly 50, the lower surface of seal assembly 50 can be connected to second
