Description

Multi-functional discharging valve

The utility model relates to a kind of discharging valve, relates in particular to and the matching used discharging valve of reaction vessel.

At present, in chemical industry, pharmacy, brewage etc. in the industry, the discharging valve of known technology, has only a tapping hole on its valve body, so the discharging valve that is installed in reaction container bottom only plays container is sealed function with blowing, therefore, reaction vessel at work, various liquid state or gaseous medium can not directly feed in the reaction vessel from discharging valve and react efficiently and effectively with material, can not adapt to more advanced, rational technological requirement.Secondly, in daily cleaning work,, especially be difficult for the valve seat that precipitated thing stops up at the bottom of the cleaning reaction container portions, influence unimpeded discharge for cleaning, the comparatively inconvenience of sterilization of in the reaction vessel and bottom and discharging valve.

The purpose of this utility model is the deficiency that overcomes the problems referred to above, and a kind of reaction vessel that not only can be applicable to various structures is provided, and can satisfy more advanced in the production process, rational technological requirement, the discharging valve with multiple function.

The utility model is that the technological scheme that achieves the above object is: a kind of multi-functional discharging valve, has spool, valve seat, have the valve body of tapping hole, bearing that is connected with valve body and spool controlling device, be provided with filler between valve body and bearing and tamp lid, the sidepiece of valve body is provided with charging aperture, and the lower end surface in the hole of the head of spool and valve seat or upper-end surface conical surface seal.

The utility model adopts has following advantage after the technique scheme: 1, because of the lower end surface conical surface in the upper-end surface in the head of spool and the hole of valve seat or hole seal close, good seal performance not only, and applicable to the reaction vessel of various structures.2, owing to set up charging aperture on the valve body, therefore not only can feed required various liquid state and gaseous medium enters in the reaction vessel from charging aperture, participate in the reaction of material in the reaction vessel, especially when feeding quantitative gas, can play the air-flow stirring action, strengthen the mixing effect in the container the medium in reaction vessel center portion, make the reaction in the container more complete, thorough, improved the conditions of manufacture of reaction vessel, improved the working efficiency of reaction vessel, also improved the quality of products.Secondly in charging aperture, can accurately grasp the course of reaction in the reaction vessel at any time to the just sampling of the reaction medium in Work container.3, discharging valve of the present utility model can directly carry out the steam rapid heating to the material in container and the container according to user's technological requirement, for reaction efficiently and effectively provides safeguard.4, in daily cleaning, disinfection, only need water and sterilised medium are got final product from charging aperture feeding discharging valve, especially directly water rinses out the precipitated thing of reaction container bottom and stops up valve seat, operates also very convenient, guarantee that spool and valve seat do not have obstruction, can unimpededly discharge material.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Fig. 1 is a kind of structural representation of the present utility model.

Fig. 2 is an another kind of structural representation of the present utility model.

Of the present utility model multi-functional discharging valve shown in Fig. 1～2, has spool (2), valve seat (3), the valve body (4) that has tapping hole (4-1), the bearing (7) and the spool controlling device that are connected with valve body (4), valve seat (3) adopt reinforced TFE and be arranged on reaction vessel and valve body (4) between, the flange plate of valve body (4) bottom is connected by fastening piece with the flange plate on bearing (7) top, be provided with polytetrafluoroethylene packing (5) and Gland (6) between valve body (4) and bearing (7) and spool (2), the sidepiece of valve body (4) is provided with charging aperture (4-2), this charging aperture (4-2) can be provided with 1 or several, and its aperture is less than the aperture of tapping hole (4-1), the bottom, hole of the charging aperture (4-2) of valve body (4) is higher than the bottom, hole of tapping hole (4-1), guarantee that material can be from the smooth emptying of drain hole (4-1), this charging aperture (4-2) also can be horizontally disposed with, for the decay resistance that makes discharging valve better, the inner chamber of valve body (4) has the Glassed Steel lining, and the outer surface of spool (2) has the Glassed Steel coating.Spool (2) is for having the hollow rod body of head, and the upper and lower end face of its head all has certain tapering, multi-functional discharging valve of the present utility model as shown in Figure 1, be arranged on the upper-end surface conical surface seal in lower end surface with the hole (3-1) of valve seat (3) of outer spool (2) head of valve body (4), formation top extending type discharging valve; Also can be as shown in Figure 2, be arranged on the lower end surface conical surface seal in the hole (3-1) of the upper-end surface of valve body (4) inner spool (2) head and valve seat (3), constitute the bottom open type discharging valve, good seal performance not only, and be suitable for various reaction vessel.

As described in Fig. 1～2, the controlling device of multi-functional discharging valve of the present utility model has little axle (12), screw mandrel (8), lifting handwheel (9) and trimming hand wheel (10), one end of screw mandrel (8) is connected with lifting handwheel (9) by key, and screw mandrel (8) screws on bearing (7), one end of little axle (12) is connected with trimming hand wheel (10) by nut, the bottom that little axle (12) passes screw mandrel (8) center hole and spool (2) spins, and the inner end end face that little axle (12) has axial convex shoulder (12-1) and screw mandrel (8) joins, rotation and lifting handwheel (9), drive screw mandrel (8), little axle (12) and spool (2) open or close valve port, rotary fine adjustment handwheel (10) is by the directly micro-spool (2) of adjusting of little axle (12), and is easy to adjust reliable.
