Problems solved by technology

[0002] At present, the spherical valves sold in the market have unreasonable design of the valve ball and the driving handle, are easy to break and fall off, and are inconvenient to maintain after the damage, and the entire valve is often replaced, which not only causes water loss control, wastes resources, but also increases the use of cost
In addition, the sealing effect of the valve is not good, and it is easy to leak water when throttling, wasting resources

Abstract

The invention discloses a spherical valve which comprises a valve body, a valve rod and a valve ball. The spherical valve is characterized in that the valve ball is arranged inside the valve body, a connecting device is arranged at the upper end of the valve ball, the upper end of the valve ball is connected with the valve rod through the connecting device, the connecting device is a protrusion arranged on the valve ball, a lug is arranged on the protrusion, the valve ball is connected to a driving rod inside the valve rod in a clamped mode through the lug, one end of the valve ball is connected with a first sealing ring, the first sealing ring is connected with a first spring, the other end of the valve ball is connected with a second sealing ring, and the second sealing ring is connected with a second spring. Due to the facts that the protrusion is arranged on the valve ball, the lug is arranged on the protrusion, and the lug is connected with the driving rod inside the valve rod in a clamped mode, the valve ball can be prevented from moving through the connecting mode, and disassembly and maintenance are easy; in addition, due to the fact that the spring is connected to the sealing ring, the sealing effect is better, and water resource waste will not be caused when the valve is closed.

Description

technical field [0001] The invention relates to a valve, in particular to a spherical valve. Background technique [0002] At present, the spherical valves sold in the market have unreasonable design of the valve ball and the driving handle, are easy to break and fall off, and are inconvenient to maintain after the damage, and the entire valve is often replaced, which not only causes water loss control, wastes resources, but also increases the use of cost. In addition, the sealing effect of the valve is not good, and it is easy to leak water when throttling, wasting resources. Contents of the invention [0003] In order to solve the above-mentioned defects and deficiencies in the prior art, the present invention provides a spherical valve, which not only has a firm connection between the valve ball and the driving handle, is easy to disassemble and maintain, but also has a good sealing effect and will not cause waste of water resources. [0004] In order to solve the abo...
