Description

A diverter ball valve with high sealing structure

technical field

The utility model belongs to the technical field of valves, in particular to a water distributor ball valve with a high sealing structure.

Background technique

The water distribution and water collector are the distribution and water collection devices used to connect the water supply and return water of various heating pipes in the water system. The water separator used in the floor heating and air conditioning system should be made of brass, and the water separator used in the renovation of the household surface of the tap water supply system is mostly made of PP or PE. Both supply and return water are equipped with exhaust valves, and many water separators are also equipped with drain valves for supply and return water. A "Y" type filter should be installed at the front end of the water supply. Valves should be installed in each branch of the water supply pipe to adjust the water volume.

The ball valve body of the existing water distributor usually connects the pipeline to the ball valve body through a liner joint, clamp and gasket, etc., and the liner joint is usually smooth. This makes there is a gap between the ball valve body and the pipeline, and the sealing is very poor. When installing, it usually causes sealing difficulties, and the installation process is complicated, and water leakage is prone to occur.

Utility model content

Aiming at the problems existing in the prior art, the purpose of the design of the utility model is to provide a water distributor ball valve with a high sealing structure.

The utility model is realized through the following technical solutions:

The water distributor ball valve with a high sealing structure includes a valve body, a valve core and a valve stem, the valve body has a water inlet port and a water outlet port, and the valve core is arranged in a cavity in the valve body Inside, one end of the valve stem passes through the valve body and is fixedly connected to the upper surface of the valve core, and the valve stem is rotatably mounted on the valve body, and the upper end of the valve stem is provided with a handle, which is characterized in that the inlet of the valve body The water outlet end is plugged with a ball valve joint, and the water outlet end of the valve body is plugged with a ball valve cap with a through hole. The ball valve cap is sleeved with a circlip. A clamping cap is sleeved on part of the outer wall of the cap and part of the valve body.

The water distributor ball valve with a high sealing structure is characterized in that the valve core is a steel ball structure, and plastic gaskets are arranged between the valve core and the inner wall of the ball valve joint and between the valve core and the inner wall of the valve.

The water separator ball valve with a high sealing structure is characterized in that an annular groove is provided on the outer wall of one end of the ball valve bonnet close to the valve body, and a first O-ring is sleeved in the annular groove, The outer wall of the end of the ball valve bonnet away from the valve body is integrally provided with a plurality of locking teeth, and the snap ring is sleeved on the locking teeth.

The water distributor ball valve with a high sealing structure is characterized in that the outer wall of the ball valve joint is integrally provided with two intervals of external threads, and the outer wall of the ball valve between the two external threads forms a concave arc A second O-ring is sleeved on the concave arc surface, and a nut is screwed on the external thread close to the end of the valve body.

The water distributor ball valve with a high sealing structure is characterized in that the handle is a straight handle.

The water distributor ball valve with high sealing structure is characterized in that a pressure cap is arranged between the inner wall of the valve and the outer wall of the valve stem.

The utility model has a reasonable structural design, and the setting of the plastic gasket and the first O-ring ensures that the joint of the valve maintains good liquid sealing performance, avoiding the occurrence of water leakage, and the setting of the retaining spring and the locking teeth realizes the firmness of the connection.

Detailed ways

The utility model is further described in detail below in conjunction with the accompanying drawings of the description, and specific implementation methods are given.

As shown in Figure 1-2, the utility model is a water distributor ball valve with a high sealing structure, including a valve body, a valve core and a valve stem. In the cavity inside the body, one end of the valve stem passes through the valve body and is fixedly connected to the upper surface of the valve core, and the valve stem is rotatably mounted on the valve body. A ball valve joint is installed at the end of the valve body, and a ball valve bonnet with a through hole is installed at the water outlet end of the valve body. A circlip is set on the bonnet of the ball valve. A card cap is sleeved on part of the outer wall.

In order to achieve a better sealing effect, the valve core is a steel ball structure, and there are plastic gaskets between the valve core and the inner wall of the ball valve joint and between the valve core and the inner wall of the valve, and on the outer wall of the end of the ball valve bonnet close to the valve body. An annular groove is provided, and the first O-ring is sleeved in the annular groove. In order to improve the stability of the connection, a plurality of latching teeth are integrally provided on the outer wall of the end of the ball valve bonnet away from the valve body. The spring is sleeved on the locking teeth.

Further, the outer wall of the ball valve joint is integrally provided with two intervals of external threads, and the outer wall of the ball valve between the two external threads forms a concave arc surface, and the concave arc surface is sleeved with a second O The type ring is screwed with a nut on the external thread close to the end of the valve body. In order to realize the tight connection between the valve stem and the valve body, a pressure cap is arranged between the inner wall of the valve body and the outer wall of the valve stem.

The utility model has the advantages of reasonable structural design, good sealing effect and simple and quick assembly.
