Abstract
The utility model relates to the technical field of valves, and provides a novel energy-saving regulating valve which saves energy sources and is good in sealing effect. The energy-saving regulating valve comprises a valve body, a valve cover and a valve core mechanism, wherein a transverse water inlet channel and a water outlet channel are arranged in the valve body; the valve cover is arranged above the valve body; a valve seat is arranged at the part where the water inlet channel is adjacent to the water outlet channel on the valve body; a valve port communicated with the water inlet channel and the water outlet channel is formed in the valve body; the valve core mechanism comprises a valve rod, a valve clack, a valve clack sealing cushion and an adjusting device; the valve clack and the valve clack sealing cushion are arranged on the valve seat in the valve body in a foldable manner; one end of the valve rod passes through the valve cover and is fixedly connected with the valve clack in the valve body; the adjusting device is arranged at the free end of the valve rod by a screw; and a sealing protruding line is arranged at a position where the valve seat is matched with the valve clack sealing cushion.
Description
Technical field
The utility model relates to valve technology field, especially a kind of energy-conservation modulating valve of good sealing effect.
Background technique
Valve is a kind of pipeline fittings, is applied in widely in the fluid circuit of every profession and trade, and it is to be used for changing path section and fluid flow direction, a kind of device of control conveyance fluid motion.Flow control valve is a kind of of valve; It is the modulating valve that changes the aperture size through the screw thread transmission that a kind of its spool is arranged in flow control valve, comprises valve body, valve gap and spool mechanism, and said valve body is provided with horizontal intake tunnel and exhalant canal; Also be provided with vertical current control channel on the said valve body; The adjacent place of the friendship of said valve body between vertical current control channel, intake tunnel and exhalant canal is provided with valve seat, and said valve gap is located at the top that valve body is positioned at vertical current control channel, and said spool mechanism is located in the vertical flow channel of valve body; But being located on the valve seat of one of which end folding, the other end stretches out outside the valve body.This flow control valve mainly relies on the seal closure of flap sealing gasket and valve seat in the spool mechanism or loosens to come by fluid flow or regulated fluid flow size, and is simple in structure, can bear higher pressure.But the pressure that only depends on valve rod to provide because of the seal closure of flap sealing gasket and valve seat makes both press close to realize that sealing effect is bad.When valve closing, because sealing effect is bad, can cause fluid to be revealed, cause waste.
Summary of the invention
Therefore, to above-mentioned problem, the utility model proposes the novel energy-conserving modulating valve of a kind of energy saving, good sealing effect.
For realizing above-mentioned purpose; The utility model has adopted following technological scheme: a kind of novel energy-conserving modulating valve, comprise valve body, valve gap, spool mechanism, and said valve body is provided with horizontal intake tunnel and exhalant canal; Valve gap is located at the valve body top; The adjacent place of friendship that said valve body is positioned at intake tunnel and exhalant canal is provided with valve seat, and said valve seat is provided with the valve port that is connected with intake tunnel and exhalant canal, and said spool mechanism comprises valve rod, flap, flap sealing gasket and controlling device; But being located in the valve body on the said valve seat of said flap and the folding of flap sealing seat; The flap that one end of said valve rod passes in valve gap and the valve body is connected, and said controlling device is located at through screw on the free end of valve rod, and the position that cooperates with the flap sealing gasket on the said valve seat is provided with the seal convexity line.
Further, be provided with spring between said valve gap and the flap.
Further, the quantity of said seal convexity line is 1.
Further, said controlling device is a handwheel.
Further, the handwheel below is provided with a scale cover on the said valve gap.
Through adopting the aforementioned techniques scheme, the beneficial effect of the utility model is: compare with existing energy-conservation modulating valve, the seal convexity line has been set up at the position that on valve seat, cooperates with the flap sealing gasket, makes sealing effect better, has reduced and can reveal in the seedbed, has practiced thrift the energy; Between valve gap and flap, set up spring, made the flap sealing gasket more closely strong with cooperating of valve seat, sealing effect is better.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
Combine accompanying drawing and embodiment that the utility model is further specified at present.
With reference to figure 1; A kind of novel energy-conserving modulating valve of the utility model comprises valve body 1, valve gap 2, spool mechanism, and said valve body 1 is provided with horizontal intake tunnel 11 and exhalant canal 12; Valve gap 2 is located at valve body 1 top; Said valve body 1 is positioned at intake tunnel 11 and is provided with valve seat 3 with the adjacent place of the friendship of exhalant canal 12, and said valve seat 3 is provided with the valve port 31 that is connected with intake tunnel 11 and exhalant canal 12, and said spool mechanism comprises valve rod 41, flap 42, flap sealing gasket 43, handwheel 44, scale cover 45; But being located in the valve body 1 on the said valve seat 3 of said flap 42 and 43 foldings of flap sealing seat; One end of said valve rod 41 passes valve gap 2 and is connected with valve body 1 interior flap 42, and said handwheel 44 is located at through screw on the free end of valve rod 41, and said scale cover 45 is located at handwheel 44 belows on the valve gap 2; Be provided with spring 5 between said valve gap 2 and the flap 42, the position that cooperates with flap sealing gasket 43 on the said valve seat 3 is provided with seal convexity line 6.
Compare with existing energy-conservation modulating valve, the seal convexity line has been set up at the position that on valve seat, cooperates with the flap sealing gasket, makes sealing effect better, has reduced and can reveal in the seedbed, has practiced thrift the energy; Between valve gap and flap, set up spring, made the flap sealing gasket more closely strong with cooperating of valve seat, sealing effect is better.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the utility model that does not break away from appended claims and limited; Can make various variations to the utility model in form with on the details, be the protection domain of the utility model.
