Abstract

The utility model discloses a hard sealing titanium ball valve, which comprises a valve body and a valve body connector connected on the valve body. A valve core chamber is formed in the valve body, two ends of a liquid inlet/ outlet of the valve core chamber are provided with valve seats, a flexible graphite mat and a spring are arranged in each valve seat, a spherical valve core is arranged in the valve core chamber, the spherical valve core is connected with a handle through a valve rod, the contact face of the valve rod and the valve body is provided with a filler, and a filler gland is arranged between the end of the filler and the handle. The titanium ball valve which adopts a hard sealing structure made of titanium material can be used under a high-temperature environment through spherical contact, and has the advantages of greatly prolonged service life, simple structure and reliable use.

Description

Hard sealing titanium ball valve
Technical field
The utility model belongs to mechanical equipment technical field, relates to a kind of hard sealing titanium ball valve.
Background technique
Existing titanium ball valve adopts soft sealing structure mostly, and soft sealing structure is confined to use under the lower temperature environments, for using in the medium of higher temperature, because the restriction of its structure, seepage takes place in soft sealing structure easy deformation and corrosion, cause damaging in advance, whole ball valve is short working life.
Summary of the invention
The purpose of this utility model provides a kind of hard sealing titanium ball valve, has solved the Environmental Conditions that the soft sealing structure that exists in the prior art can not adapt to higher temperature, and whole ball valve short problem in working life solves the problem of titanium material affinity simultaneously.
The technological scheme that the utility model adopted is, a kind of hard sealing titanium ball valve, comprise valve body and be connected valve body connecting body on the valve body, be provided with valve core chamber in the valve body, the liquid entrance two ends of this valve core chamber are provided with valve seat, and Expanded graphite pad and spring are installed in the valve seat, also be provided with spherical valve core in this valve core chamber, spherical valve core is connected with handle by valve rod, and the surface of contact of valve rod and valve body is provided with filler, is provided with Gland between the termination of filler and the handle.
Hard sealing titanium ball valve of the present utility model, its feature also is: described valve seat and spherical valve core are all selected titanium material foundry goods for use.
Device of the present utility model, the hard sealing structure of employing titanium material by the contact of sphere face, can use under the higher temperature environment, and increase substantially working life, simple in structure, uses reliable.
Description of drawings
Fig. 1 is the structural representation of the utility model device.
Among the figure, 1. valve body connecting body, 2. valve seat, 3. Expanded graphite pad, 4. spring, 5. spherical valve core, 6. valve body, 7. valve rod, 8. Gland, 9. handle, 10. filler.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As Fig. 1, the structure of hard sealing titanium ball valve of the present utility model is, comprise valve body 6 and be connected valve body connecting body 1 on the valve body 6, be provided with valve core chamber in the valve body 6, the liquid entrance two ends of this valve core chamber are provided with valve seat 2, and Expanded graphite pad 3 and spring 4 are installed in the valve seat 2, also be provided with spherical valve core 5 in this valve core chamber, spherical valve core 5 is connected with handle 9 by valve rod 7, and valve rod 7 is provided with filler 10 with the surface of contact of valve body 6, is provided with Gland 8 between the termination of filler 10 and the handle 9.
Spherical valve core 5 adopts titanium material to make, and Wear-resistant, high-temperature resistant excellent performance, spherical valve core 5 are provided with two parallel tangent planes, are fluid passage between two tangent planes, and the distance between two tangent planes is less than the distance between the two ends valve seat 2.
Hard sealing titanium ball valve working principle of the present utility model is,
When need opening ball valve, turn handle 9 and drive spherical valve cores 5, when spherical valve core 5 turns to fluid passage between two tangent planes when communicating with the import and export axis of valve body 6, stop to turn handle 9, this moment, spring 4 and Expanded graphite pad 3 positions remained unchanged;
In the time of need closing ball valve, turn handle 9 and drive spherical valve core 5, when spherical valve core 5 turns to the import and export axis normal of fluid passage between two tangent planes and valve body 6, the import and export passage of valve body 6 is closed, at this moment, because the roof pressure of spherical valve core 5 cylindricals, Expanded graphite pad 3 is outwards along with bending deflection, but Expanded graphite pad 3 can guarantee the sealing between spherical valve core 5 and the valve seat 2 all the time, realizes the sealing of whole ball valve.
Titanium ball valve of the present utility model adopts the hard sealing structure of titanium material, by the sphere contact, can use under the higher temperature environment, and increase substantially working life, simple in structure, uses reliably, and beautiful shape solves the problem of titanium material affinity simultaneously.
