Description

Technical Field

[0001] The invention relates to the technical field of mechanical equipment, in particular to a novel three-way ball valve. Background Art

[0002] There are two types of three-way ball valves: T-type and L-type. The T-type can connect three orthogonal pipelines to each other and cut off the third channel, playing the role of diversion and confluence. The L-type three-way ball valve can only connect two orthogonal pipelines, and cannot keep the third pipeline connected at the same time, and only plays a distribution role.

[0003] Due to the structural characteristics, a certain amount of fluid will accumulate at the bottom of the valve body. These fluids are not easy to discharge, which causes the accumulated fluid to continuously corrode the valve body and the ball. The fluid can only be discharged by opening the lid of the sealing ball, which is very troublesome. Due to the sealing conditions, it becomes difficult to install the ball. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies of the prior art, the present invention provides a novel three-way ball valve, which solves the problem that the fluid accumulated in the valve body cannot be discharged during the use of the three-way ball valve and the ball is inconvenient to install.

[0006] (II) Technical solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a novel three-way ball valve comprises a valve body, the left side surface of the valve body is fixedly connected to the right valve port, a valve seat is arranged inside the valve body, a ball is rotatably connected to the side of the valve seat away from the valve body, a pit is arranged in the middle of the lower surface of the ball, the lower surface of the valve body is fixedly connected to a base, an adjusting hole is arranged in the middle of the base, a connecting button is fixedly connected to the lower part of the valve body, a drainage channel is arranged inside the connecting button, a fixing plate is slidably connected to the lower part of the valve body, a connecting pipe is fixedly connected to the middle part of the valve body, a spring is arranged between the fixing plate and the connecting button, a fixing ball is fixedly connected to the upper end of the connecting pipe, the fixing ball is rotatably connected to the pit, a sealing ring is arranged on the side wall of the connecting pipe and between the fixing ball and the fixing plate, and a sealing ring is arranged on the outer surface of the connecting pipe and between the fixing ball and the fixing plate. The closure of the valve body is provided with a first sealing ring, and a second sealing ring is provided on the closure of the valve body to prevent the closure of the valve body from leaking out.

[0008] Preferably, the spring is located on the outer surface of the connecting pipe, and one end of the connecting pipe away from the fixing ball extends into the drainage channel.

[0009] Preferably, the sealing ring is in contact with the lower portion of the valve body and is located below the water inlet hole.

[0010] Preferably, the countersunk hole is located on the left side of the nut, and the right valve port, the left valve port and the front valve port are provided with connecting holes at the outer edge away from the valve body.

[0011] Preferably, a section of the valve stem with a smaller cross-sectional area passes through the end cover, and the upper portion of the sealing member is located on the inner side of the boss.

[0012] Preferably, the valve seat is respectively arranged on the left and lower parts of the inner surface of the valve body and the inner side of the mounting ring.

[0013] Preferably, the water inlet is connected to the drainage channel, and the drainage channel is connected to the outside. Working principle: after removing the second sealing ring, remove the bolts and nuts fixing the sealing body and the left valve port, loosen the nut in the countersunk hole, and then remove the first sealing ring, the mounting ring, and the valve seat contacted by the mounting ring connected to the sealing body, remove the end cover, and then pull the valve stem to separate the cross plug from the ball, and then take the ball out of the valve body. When installing the ball, push the ball in and make the pit contact with the fixed ball, and at the same time rotate the ball to insert and fix the end cover, then install the mounting ring and the valve seat contacted by the mounting ring, the first sealing ring, and the sealing body, and then tighten the nut in the countersunk hole, install the bolts and nuts and tighten them, and then install the second sealing ring. After turning the connecting button, the outlet of the drainage channel is turned to the outside of the valve body. At this time, the fluid between the valve body and the ball can flow out of the drainage channel through the water inlet and the connecting pipe, and the vibration generated during the rotation of the ball will be transmitted to the spring for reduction.

[0014] (III) Beneficial effects

[0015] The present invention provides a novel three-way ball valve. It has the following beneficial effects:

[0016] 1. In the present invention, after removing the second sealing ring, the sealing body, the mounting ring and the valve stem, the ball can be installed into or removed from the valve body, which is very convenient. The mounting ring and the valve seat can contact the ball and play a supporting role. The two sealing rings and the sealing member can provide good sealing performance.

[0017] 2. The present invention uses a fixed ball supported in the pit of the sphere, so that the vibration generated by the sphere can be reduced by the spring, thereby extending its service life. When the connecting button is turned downward, the outlet of the drainage channel reaches the outside of the valve body, so that the stagnant fluid can enter the connecting pipe and the drainage channel from the water inlet hole and then flow out. This is very convenient during the use of the three-way ball valve. BRIEF DESCRIPTION OF THE DRAWINGS
