Abstract
The utility model relates to a valve, in particular to a special throttle control valve for chlorine, which is used for controlling and adjusting the flow of media on pipelines of the chemical industry. The special throttle control valve for chlorine comprises a valve body, a valve seat, a valve clack, a valve cover, a gland, a valve stem, a driving nut and a hand wheel, wherein a convex body of which the diameter gradually decreases from top to bottom is arranged at the bottom of the valve clack. The special throttle control valve for chlorine has the advantages of long service life and medium flow adjustment.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to control on a kind of chemical industry pipeline and regulate the special-purpose throttling modulating valve of chlorine of media flow.
Background technique
At present, the valve that China's chemical industry is used for the control of deep-etching flowing medium such as chlorine mostly is common shutoff valve greatly, owing to adopted common flap, can not accurately regulate rate-of flow, and medium impacts big to flap, causes valve short working life, changes frequent, influence is produced, and causes very serious economy loss and inevitably potential safety hazard.
Summary of the invention
The purpose of this utility model is: the special-purpose throttling modulating valve of chlorine that a kind of long service life and can regulate rate-of flow are provided.
The purpose of this utility model is achieved in that the special-purpose throttling modulating valve of a kind of chlorine, comprises valve body, valve seat, flap, valve gap, gland, valve rod, transmission nut, handwheel, and described flap bottom is provided with the convex body that diameter diminishes from top to bottom gradually.
As a kind of improvement of the present utility model, described flap middle part is provided with annular groove along outer circumferential walls.
The convex body structure is adopted in flap of the present utility model bottom, thereby the user can according to the needs of operating mode flow voluntarily the aperture of regulating valve obtain the needed flow of user, solve common shutoff valve and can not accurately regulate the problem of rate-of flow, and prolonged working life.
The flap middle part is provided with annular groove along outer circumferential walls, adopts " worker " shape structure, plays the effect of throttling, greatly reduces the erosion of pipeline internal medium to valve sealing element, thereby has prolonged the working life of valve.
In sum, the utility model long service life and can regulate rate-of flow.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
As shown in Figure 1, the special-purpose throttling modulating valve of a kind of chlorine comprises valve body 1, valve seat 2, flap 3, valve gap 4, gland 5, valve rod 6, transmission nut 7, handwheel 8, and flap 3 bottoms are provided with the convex body 9 that diameter diminishes from top to bottom gradually; Flap 3 middle parts are provided with annular groove 10 along outer circumferential walls.
During use, rotation hand wheel 8 drives valve rod 6, flap 3 upper and lower displacements, and flap 3 separates with valve seat 2 when to top offset, is valve opening; When flap 3 during to bottom offset, flap 2 coincide with valve seat 2 and connects, and is valve closing.
Claims (2)
1. the special-purpose throttling modulating valve of chlorine comprises valve body, valve seat, flap, valve gap, gland, valve rod, transmission nut, handwheel, it is characterized in that: described flap bottom is provided with the convex body that diameter diminishes from top to bottom gradually.
2. the special-purpose throttling modulating valve of chlorine according to claim 1 is characterized in that: described flap middle part is provided with annular groove along outer circumferential walls.
