Abstract
The utility model discloses a partial derivation control ball valve which can reduce the friction of a control valve to the minimum, improve control property and use life and has convenient and flexible operation. The utility model adopts the following technical scheme: the partial derivation control ball valve comprises an upper valve rod, a lower valve rod, an upper bearing, a lower bearing, a valve body, a spring, a gland, a valve core and a valve seat, and is characterized in that the valve core and the valve body are eccentric, and can contact only in the opening less than five DEG in the opening and closing; the valve seat is a movable valve seat; a pre-tightening spring enabling the valve seat to tightly cling to the valve core is arranged between the valve body and the valve seat; and a sealing pieces is arranged on the combined surface of the valve body and the valve seat.
Description
Technical field
The utility model relates to a kind of control ball valve, particularly a kind of little inclined to one side control ball valve.
Background technique
The control ball valve is the widely used class control valves of industry such as Coal Chemical Industry, refinery, papermaking, and medium is mainly fibre-bearing, high viscosity, contains the fluid of solid particle.In the control valve field, frictional force is to influence one of modal factor of control valve ride quality, the frictional force of control ball valve mainly is that spool remains to contact with valve seat and brings, the whole control process operational torque is all bigger, control dumb, and the wear problem of valve seat and spool is more serious, influences working life.
The model utility content
The purpose of this utility model provides and a kind ofly control valve frictional force can be dropped to minimumly, improves control performance and working life, and the little inclined to one side control ball valve of operation light and flexible.
The purpose of this utility model is achieved through the following technical solutions: little inclined to one side control ball valve, comprise lower valve rod, metal (upper, valve body, spring, gland, spool and valve seat, it is characterized in that institute's book spool and valve body are eccentric V-shaped valve core and valve body, spool only contacts spending in the apertures less than 5 of keying with valve seat, and all the other aperture scope inner spools all do not contact with valve seat.
Valve seat is removable valve seat, is provided with the preloading spring that valve seat and spool are fitted tightly between valve body and the valve seat, is provided with Sealing on the junction plane of valve body and valve seat.
The sealing vice division chief that valve seat contacts with spool is provided with the tip-angled shape doctor blade device.
Spool is supported by metal (upper.
Effect of the present utility model is: adopt two eccentric center principles that spool is only contacted in the little aperture that opens and closes with valve seat, all the other aperture scope inner spools all do not contact with valve seat, effectively frictional force is dropped to minimum, the dynamic torque that will influence stability simultaneously also drops to minimum, thereby guarantee that control action is steady, also improve working life simultaneously.
Valve seat is removable valve seat, is provided with the preloading spring that valve seat and spool are fitted tightly between valve body and the valve seat, is provided with Sealing on the junction plane of valve body and valve seat.By preloading spring make removable valve seat when closing and spool keep certain seal pressure, improve sealability, and spool and valve seat kept in touch in little aperture scope by removable valve seat, improve control accuracy.
Valve body and spool are small eccentric structure, by off-centre valve seat is not contacted in the aperture on a large scale with spool, but because off-centre is very little, so even valve seat and spool break away from, the gap is also very little, can guarantee control performance like this, make Flow characteristics more be similar to the equal percentage flow characteristic of standard.
The sealing vice division chief that valve seat contacts with spool is provided with the tip-angled shape doctor blade device, can strike off the dirt and the medium crystallization of adhering on the spool, has self-cleaning function.
Description of drawings
Fig. 1 is the structural representation of little inclined to one side control ball valve;
Fig. 2 is the A portion enlarged view of Fig. 1.
Embodiment
Now accompanying drawing is further described the utility model in conjunction with the embodiments, and certain protection domain of the present utility model is not limited to the embodiment in the accompanying drawing.
As shown in Figure 1, the little inclined to one side control ball valve of the utility model comprises lower valve rod 1, valve body 2, lower bearing 3, spool 4, spring 5, valve seat 6, upper valve rod 7, upper bearing (metal) 8, gland 9, drive upper valve rod 7 by actuator and reach spool 4 rotations that are connected with upper valve rod 7 splines, change by flow area realizes control procedure, upper valve rod 7 has upper bearing (metal) 8 and lower bearing 3 to support respectively with lower valve rod 1, metal (upper adopts the little material of friction factor, reduce the operation moment of torsion, upper valve rod 7 has a small throw of eccentric with the sphere centre of lower valve rod 1 and valve seat 6 and spool 4, realize that by this throw of eccentric 4 of spools contacted with valve seat 6 in the moments that open and close, all the other processes then spool 4 break away from valve seat 6, but it is very little to break away from the gap; There is the valve seat 6 of certain mobile space to guarantee that by gland 9 and spring 5 spool 4 is had certain contact in the little aperture of keying in addition; So just make spool 4 when closing, 4 pairs of valve seats 6 of spool have certain sealing load, valve seat 6 also has certain sealing load by 5 pairs of spools 4 of spring simultaneously, sealability is reliable and stable, when little aperture, valve seat 6 still contacts with spool 4, the precision of the control of valve when having guaranteed little aperture, in surpassing most of aperture of little aperture, valve seat 6 is separated from a little gap with spool 4, effectively frictional force is dropped to minimum, drop to the dynamic torque that influences control valve stability minimum, reduce the wearing and tearing of sealing pair simultaneously, both improved the control performance of valve, also prolonged the working life of valve
Reveal in order to prevent that valve seat and valve body junction from producing, be provided with Sealing 10 in valve seat 6 and valve body 1 joint, on the inner side edge of valve seat 6, also be provided with tip-angled shape scraper 11 in addition, strike off the dirt and the medium crystal that adhere on the spool, have self-cleaning function.
