Injap bola besi tuang

Injap bola besi Besi adalah injap pengedap paksa, jadi apabila injap ditutup, tekanan harus diberikan pada cakera untuk memaksa permukaan pengedap agar tidak bocor. Apabila medium memasuki injap dari bawah cakera, rintangan yang perlu diatasi oleh daya operasi adalah daya geseran batang injap dan pembungkusan dan daya tarikan yang dihasilkan oleh tekanan medium. Gaya untuk menutup injap lebih besar daripada daya untuk membuka injap, jadi Besi tuang Diameter batang injap injap globe harus besar, jika tidak, batang injap akan membengkokkan kegagalan.

1. PengenalanBesi tuangGlobusValve

Besi tuangglobusvalve is a forced-sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface to not leak. When the medium enters the valve from below the disc, the resistance that the operating force needs to overcome is the friction force of the valve stem and packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so Besi tuangThe diameter of the valve stem of the globusvalve should be large, otherwise the valve stem will bend up failure.

3. Advantages of Besi tuangglobusvalve

1) The structure of the Besi tuangglobusvalve is simpler than that of the gate valve, and it is more convenient to manufacture and maintain.
2) Permukaan kedapof Besi tuangglobusvalve is not easy to wear and scratch, and the sealing performance is good. There is no relative sliding between the valve disc and the sealing surface of the valve body when opening and closing, so neither abrasion nor abrasion is serious. The sealing performance is good and the service life is long. .
3) When the Besi tuangglobusvalve is opened and closed, the disc stroke is small, so the height of the shut-off valve is smaller than that of the gate valve, but the structure length is longer than that of the gate valve.
4) Besi tuangglobusvalve has a large opening and closing moment, which is laborious and takes a long time.
5) The medium channel in the Besi tuangglobusvalve is tortuous, the fluid resistance is large, and the power consumption is large.
6) When the nominal pressure of the medium flow direction of the Besi tuangglobusvalve PN≤16MPa, the downstream flow is generally adopted, and the medium flows upward from the bottom of the valve flap; when the nominal pressure PN≥20MPa, the reverse flow is generally adopted, and the medium flows downward from the top of the valve flap. In order to increase the seal performance. When in use, the shut-off valve medium can only flow in one direction and cannot change the direction of flow.
7) The valve flap is often eroded when the Besi tuangglobusvalve is fully opened.
