Description

Self-cleaning hard sealing ball valve

Technical Field

The utility model relates to the field of valves, in particular to a self-cleaning hard sealing ball valve.

Background

Ball valves are commonly used connections in pipe connections.

The further improvement is that: the clamping device comprises a magnetic connecting ring, the filter screen is fixedly arranged in the connecting ring, the connecting groove is formed in the filter pipe, the connecting ring is arranged in the connecting groove, and a magnetic block which is magnetically attracted with the connecting ring is fixedly arranged inside the connecting groove in the filter pipe.

The further improvement is that: the filter pipe is in threaded connection with the inner wall of the water inlet channel.

The further improvement is that: a sealing groove is formed in the connecting disc, and a sealing ring is arranged in the sealing groove.

The further improvement is that: the filter tube is internally provided with a first baffle and a second baffle which are respectively positioned at two ends of the filter tube and are arranged in a staggered manner.

The further improvement is that: and a hand wheel is arranged on the valve rod.

The utility model has the advantages and the beneficial effects that:

1. simple structure and convenient use. The filter screen can filter the impurity in the inhalant canal rivers, avoids impurity and dirt to pile up on the valve plate, is favorable to protecting the valve plate, improves valve life.

2. The filter screen can be conveniently cleaned and replaced through the filter pipe.

3. First baffle and second baffle have the waterproof hammer function, further improve the life of ball valve.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1, a self-cleaning hard sealing ball valve, including valve body 1, filter tube 8, have magnetic go-between 13, set up in valve gap 6, valve rod 5 above valve body 1, along radially the inhalant canal 2 and the exhalant canal 3 of seting up, set up in inhalant canal 2 with be used for controlling the valve plate 4 that the fluid opened and close between the exhalant canal 3, valve rod 5 locates inside and being located of valve body 1 valve plate 4 top, first passageway has been seted up to valve gap 6 top, the lower tip of valve rod 5 with valve plate 4 is connected, wear out in valve rod 5 upper end first passageway, filter tube 8 one end is worn to locate through threaded connection on valve body 1 and be located inhalant canal 2, filter tube 8 other end is fixed to be equipped with connection pad 9 that opposes with external pipeline, the seal groove has been seted up on connection pad 9, be equipped with sealing washer 10 in the seal groove, be equipped with filter screen 12 and filter screen 12 on the filter tube 8 and be located the inhalant canal 8's mouth department of filter screen 12, filter screen 12 is fixed to be located in the go-between 13, the go-between filter tube 8 has seted up the spread groove, the go-between is located in the magnetic block 13, filter tube 8 internal fixation is equipped with the go-between and the magnetic connection groove 13.

In order to prevent the generation of water hammer and avoid the occurrence of water hammer to the valve plate 4, a first baffle 14 and a second baffle 15 are fixedly arranged in the filter pipe 8, and the first baffle 14 and the second baffle 15 are respectively positioned at two ends of the filter pipe 8 and are arranged in a staggered manner.

In order to conveniently open and close the ball valve, a hand wheel is arranged on the valve rod.

The working principle is as follows:

when the ball valve is used, the filter pipe 8 is screwed out, then the filter pipe is resisted with an external connecting pipe, and then the filter pipe is connected with an external pipeline through a flange plate on the ball valve, so that the installation is completed. At this time, the fluid medium is filtered from the external pipeline through the filter screen 12 and then enters the filter pipe 8, and then flows into the water inlet channel 2 of the ball valve, so that impurities are prevented from being attached to the inside of the ball valve. When the filter screen 12 blocks up, as long as with 8 screw threads of filter tube get into inhalant canal 2 in, pull down filter screen 12, wash, then put into again, spiral filter screen 12 with the connecting pipe offset can, avoid all to pull down the ball valve, be favorable to the staff to maintain.

Having shown and described the basic principles and essential features of the invention and its advantages, it will be understood by those skilled in the art that the present invention is not limited by the embodiments described above, which are merely illustrative of the principles of the invention, but is susceptible to various changes and modifications without departing from the spirit and scope of the invention, all of which are intended to be covered by the appended claims and their equivalents.
