Abstract
The utility model provides an integrated inclined surface type ball valve, and relates to a valve. The integrated inclined surface type ball valve comprises a valve body, a valve seat, a ball body, a spring, a gland box, a valve rod and a handle, wherein the valve body is integrated and is connected with the valve seat; the ball body is arranged in the valve body and is connected with the lower end of the valve rod; two inclined surfaces are formed on the ball body, and water holes are formed in the inclined surfaces; the spring is arranged on the ball body; the upper end of the valve rod is connected with the gland box; and the handle is connected with the top end of the valve rod. The ball valve is simple and reasonable in structure, light and convenient to operate, small in switch-on/switch-off torque and convenient to maintain; and once a seal pair is worn, the automatic compensation can be realized by the spring force, therefore, the sealing performance of the valve is improved, and the service life of the ball valve is prolonged.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of integral ramp type ball valve.
Background technique
Since China reform and opening-up, national economy obtains rapid growth, and " scientific and technical innovation, autonomous innovation " become the main flow of the present industrial development of China, and China's industry is progressively to intensive style, energy-saving and emission-reduction, the future development of low-carbon (LC).Ball valve is to utilize spheroid as the valve body of open-shut device, and during work, spheroid does around the valve body center line opening and closing that rotation reaches valve.Ball valve mostly is greatly side-mounted at present, and this kind structure ubiquity and opened and closed the large drawback of moment.When being subject to the temperature difference and pipeline affecting of stress is installed, increased keying moment or caused leakage.On the long-term sealing pair that uses late gate and valve rod, the seal ring place is easy to wear but self can not get mending and taste, and working life is short, easily causes medium to leak outside, and must pull down valve from pipeline during maintenance, and is time-consuming.In order to address these problems, R﹠D institution and science and technology in enterprise personnel utilize modern science and technology in constantly research, exploration, although obtained technically some progress, still exist the technical barrier that not yet overcomes in practice.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, and a kind of integral ramp type ball valve is provided, and is rational in infrastructure, opens and closes moment little, only need take valve gap apart during maintenance, can safeguard.The sealability of valve seal pair is not subjected to the temperature difference and pipeline that the impact of stress is installed, and when sealing pair wear and tear, spring force energy auto-compensation had improved the sealability of valve.
The technological scheme that its technical problem that solves the utility model adopts is: contain valve body, valve seat, spheroid, spring, Stuffing box, valve rod, handle, valve body is integrated type, valve seat is connected with valve body, is provided with spheroid in valve body, and spheroid is connected with the lower end of valve rod, two inclined-planes are arranged on spheroid, the inclined-plane is provided with water passage hole, and spheroid is provided with spring, and the upper end of valve rod is connected with Stuffing box, handle is connected with the top of valve rod, has formed a kind of integral ramp type ball valve.
The know-why that its technical problem that solves the utility model adopts is: existing ball valve is improved innovation, and valve body is integrated type, and the temperature difference and pipeline are installed stress can not affect the sealability of ball seal pair.The valve body of this valve is the same with the principle of Wedge gate valve, spheroid has two inclined-planes, the water passage hole of spheroid and the centre of sphere have a bias, spheroid has just formed certain inclined-plane like this, spheroid and two seal rings are packed into together and are processed in advance in the valve body on inclined-plane, just can reach sealing by two inclined-planes and Compress Spring, when sealing pair wore and tore, spring force can auto-compensation.The soft seal valve seat is bumped in metallic sleeve gasket, and the metal coating circle is arranged outward, and to reduce the valve seat distortion, metallic sleeve gasket also can play fireproofing function, in case the soft seal seat is burnt in breaking out of fire, metallic sleeve gasket can also play seal action, prevents that medium from leaking outside in a large number.The valve rod of this ball valve adopts down-mounting type, and the nut on valve rod is tightened in the packing seal of top one circle and following two circles, just can guarantee valve stem seal.This ball valve operation is light, opens and closes moment and only is below 50% of ball valve commonly used.When needing repairing, as long as valve gap is taken apart, can safeguard, will not pull down from pipeline by valve.
The utility model beneficial effect is: this ball-valve structure advantages of simple, operate lightly, and open and close moment little, be convenient to maintenance.When sealing pair wore and tore, spring force can auto-compensation, had improved the sealability of valve, had extended the working life of ball valve.
Description of drawings
The below further describes the utility model in conjunction with the accompanying drawings and embodiments:
It is a kind of structural representation of integral ramp type ball valve in figure.
In the drawings: 1. valve body, 2. valve seat, 3. spheroid, 4. spring, 5. Stuffing box, 6. valve rod, 7. handle.
Embodiment
In the drawings: valve body 1 is integrated type, valve seat 2 is connected with valve body 1, be provided with spheroid 3 in valve body 1, spheroid 3 is connected with the lower end of valve rod 6, and two inclined-planes are arranged on spheroid 3, and the inclined-plane is provided with water passage hole, spheroid 3 is provided with spring 4, the upper end of valve rod 6 is connected with Stuffing box 5, and handle 7 is connected with the top of valve rod 6, has formed a kind of integral ramp type ball valve.
Existing ball valve is improved innovation, and valve body 1 is integrated type, and the temperature difference and pipeline are installed stress can not affect the sealability of spheroid 3 sealing pairs.The valve body 1 of this valve is the same with the principle of Wedge gate valve, spheroid 3 has two inclined-planes, the water passage hole of spheroid 3 and the centre of sphere have a bias, spheroid 3 has just formed certain inclined-plane like this, the preliminary election of packing into together of spheroid 3 and two seal rings processes in the valve body 1 on inclined-plane, just can reach sealing by two inclined-planes and Compress Spring 4, when sealing pair wore and tore, spring 4 power can auto-compensation.Soft seal valve seat 2 is bumped in metallic sleeve gasket, and the metal coating circle is arranged outward, and to reduce valve seat 2 distortion, metallic sleeve gasket also can play fireproofing function, in case the soft seal seat is burnt in breaking out of fire, metallic sleeve gasket can also play seal action, prevents that medium from leaking outside in a large number.The valve rod 6 of this ball valve adopts down-mounting type, and the nut on valve rod 6 is tightened in the packing seal of top one circle and following two circles, just can guarantee valve rod 6 sealings.This ball valve operation is light, opens and closes moment and only is below 50% of ball valve commonly used.When needing repairing, as long as valve gap is taken apart, can safeguard, will not pull down from pipeline by valve.
