进口平衡式调节阀Product Description:

The utility model comprises a valve core, a valve cage and a valve cage gland, the valve core is sliding on the valve cage, the outer wall surface of the valve cage gland is attached to the inner wall surface of the valve cage, the valve cage is provided with a support platform, a holding space is formed between the bottom of the valve cage gland and the support platform, the metal sealing ring is located in the holding space, and the metal sealing ring is pressed on the support platform, the metal sealing ring is provided with an annular groove, and the annular groove separates the metal sealing ring into an inner sealing ring and an outer sealing ring, Both the inner seal ring and the outer seal ring have spherical surfaces, and the spherical surface of the outer seal ring butts against the inner wall surface of the valve cage; When the balance regulating valve is closed, the spherical surface of the inner sealing ring butts against the outer wall of the valve core; When the balance regulating valve is in the flow closed state, the opening of the annular groove faces the support platform; When the balance regulating valve is in the flow open state, the opening of the annular groove faces the bottom of the cage gland. The balanced regulating valve has better sealing effect and longer service life of the sealing ring.

进口平衡式调节阀characteristic:

Due to the sealing effect achieved by pressing, the output force of the balanced regulating valve will be too large in the actual use process, and the sealing surface will be seriously worn, which will produce leakage after long-term use, resulting in the shortening of the service life of the valve. The double seat valve core in the balance regulating valve in the prior art belongs to the over positioning form, which is difficult to achieve good sealing effect.

进口平衡式调节阀Principle:

A valve core, a valve cage and a valve cage gland, the valve core is sliding on the valve cage, the valve cage gland is embedded at one end of the valve cage, and the outer wall surface of the valve cage gland is close to the inner wall surface of the valve cage. It is characterized in that the inner wall surface of the valve cage is provided with a support platform, a holding space is formed between the bottom of the valve cage gland and the support platform, a metal sealing ring is sleeved on the valve core and located in the holding space, and the metal sealing ring is pressed on the support platform, An annular groove is arranged on the metal sealing ring, which separates the metal sealing ring into an inner sealing ring and an outer sealing ring. Both the inner sealing ring and the outer sealing ring have a spherical surface, and the spherical surface of the outer sealing ring is butted with the inner wall surface of the valve cage;
