Description
Technical Field
The invention belongs to the technical field of ball valves, and particularly relates to a three-section type ball valve with a soft sealing structure.
Background
The ball valve, the opening and closing piece (spheroid) is driven by the valve stem, and round the valve that the ball valve axis makes rotary motion, also can be used to fluidic regulation and control, wherein have very strong shearing force between its V type ball core of the hard seal V-type ball valve and the metal valve seat of the build-up welding carbide, the medium that is particularly useful for containing fibre, tiny solid particle etc., and the multiple-way ball valve not only can control the confluence of medium, reposition of redundant personnel, and the switching of flow direction in a flexible way on the pipeline, also can close arbitrary passageway and make two other passageways link to each other simultaneously.
According to the three-piece type integral valve seat soft seal ball valve with the Chinese patent number 'CN 201020232583.8', a structure matched with an installation groove is arranged on a valve seat, the existing three-section type soft seal ball valve is obtained, the left end and the right end of the valve ball are usually sealed by sealing rings, and the sealing structure does not completely surround the valve ball, so that the sealing performance is reduced due to the loosening of the sealing rings after a long time.
It can be seen that the prior art has at least the following disadvantages: the left end and the right end of the valve ball are usually sealed by sealing rings, so that the sealing performance is reduced due to the loosening of the sealing rings after a long time.
Therefore, it is necessary to provide a technical means to solve the above-mentioned drawbacks.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a three-section type soft sealing structure ball valve to solve the problem that the sealing performance is reduced due to the looseness of a sealing ring after a long time because the left end and the right end of the ball valve are usually sealed by the sealing ring in the prior art.
The invention is realized in this way, the ball valve of three-segment soft seal structure, including:
the valve body, the valve body includes sealed tube, valve ball, disk seat, valve gap and valve rod, the disk seat is located the valve body lower extreme, the valve gap is located the valve body upper end, the valve rod alternates and the swivelling joint is inside the valve gap, the valve rod lower extreme extends to the inside scarf joint fixed valve ball of valve body, the inside sealed tube that just is located valve ball external fixation and valve ball rotation connection of valve body, the intercommunication mouth, every are all opened at both ends about the sealed tube the fixed sealing ring of laminating mutually with the valve ball of intercommunication mouth inner wall all scarf joint, the draw-in groove has all been opened to the left and right sides at both ends about the valve body inner wall, the left and right sides at both ends all is fixed with rather than the kelly as an organic whole about the sealed tube, the kelly.
Furthermore, a water through opening is formed in the valve ball, and the left end and the right end of the water through opening are both open ends.
Specifically, the aperture of the communication port is equal to the aperture of the water passage port, and the communication port is communicated with the water passage port.
Further, the valve ball is respectively embedded and rotatably connected with the valve seat and the valve cover.
In particular, the sealing tube is made of PVC plastic.
Compared with the prior art, the invention has the beneficial effects that:
this kind of soft seal structure ball valve of syllogic carries out whole encircleing the valve ball through the sealed tube, and the sealed tube is fixed through the inside joint of kelly insertion draw-in groove moreover for the sealed tube possesses stability, when long-time the use, not only is difficult to appear becoming flexible, and can increase the leakproofness between valve ball and the valve body through sealed tube and sealing ring.
Drawings
FIG. 1 is an overall schematic view of the present invention;
FIG. 2 is a schematic view of the left end of the sealing tube of the present invention.
In the figure: the valve comprises a valve body 1, a sealing pipe 2, a valve ball 3, a clamping rod 4, a clamping groove 5, a sealing ring 6, a valve seat 7, a valve cover 8, a valve rod 9 and a communication port 10.
Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
As shown in fig. 1 to 2, a preferred embodiment of the present invention is a three-stage soft seal ball valve, including: the valve body 1, the valve body 1 includes a sealing tube 2, a valve ball 3, a valve seat 7, a valve cover 8 and a valve rod 9, the valve seat 7 is located at the lower end of the valve body 1, the valve cover 8 is located at the upper end of the valve body 1, the valve rod 9 is inserted and rotatably connected inside the valve cover 8, the lower end of the valve rod 9 extends into the valve body 1 to be embedded and fixed with the valve ball 3, the valve ball 3 is respectively embedded and rotatably connected with the valve seat 7 and the valve cover 8, a water passage opening is formed inside the valve ball 3, and the left end and the right end of the water passage opening are open ends, firstly, when the open end of the water passage opening of the valve ball 3 rotates by ninety degrees along with the valve rod 9 and rotates from the left end and the right end to the front end and the back end between the valve seat;
according to the above embodiment, further, the valve body 1 is located outside the valve ball 3 and is fixed with the sealing tube 2 rotatably connected with the valve ball 3, the sealing tube 2 is opened with the communicating ports 10 at the left and right ends, the inner wall of each communicating port 10 is embedded and fixed with the sealing ring 6 attached to the valve ball 3, the diameter of the communicating port 10 is equal to the diameter of the water passing port, the communicating port 10 is communicated with the water passing port, the sealing tube 2 is made of PVC plastic, when the water passing port of the valve ball 3 faces the left and right ends, as the water passing port is communicated with the communicating port 10, the liquid can flow into the water passing port in the valve ball 3 along the communicating port 10 of the sealing tube 2, so that the liquid can flow, when the valve ball 3 rotates ninety degrees to make the water passing port not communicated with the communicating port 10, the valve ball 3 plugs the communicating port 10 of the sealing tube 2, as the sealing tube 2 completely surrounds the valve ball 3, so that the sealing performance between the valve ball 3 and the valve body 1 is increased, and the sealing performance between the valve ball 3 and the sealing pipe 2 can be increased along with the sealing ring 6 clinging to the valve ball 3, thereby further improving the sealing performance;
according to the embodiment, as preferred, draw-in groove 5 has all been opened to the left and right sides at both ends about the valve body 1 inner wall, the left and right sides at both ends all is fixed with rather than kelly 4 as an organic whole about gland seal 2, kelly 4 inserts inside and the 5 joints of draw-in groove 5, when valve ball 3 is in the pivoted, because gland seal 2 inserts inside and the joint of draw-in groove 5 through kelly 4 and fixes in valve body 1 for gland seal 2 not only possesses stability when valve ball 3 rotates, and when long-time the use, is difficult to appear becoming flexible moreover.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention.
