Abstract
The utility model relates to an unloading valve, comprising a valve body, a seal valve plate which is assembled in the valve body, and an actuating mechanism which drives the opening and the closing of the seal valve plate. The seal valve plate is composed of a supporting body and a valve plate, and the supporting body and the valve plate can be integrally fastened. The supporting body is connected with a valve rod. A valve seat which is matched with the valve plate is arranged on the valve body. The valve seat and the seal valve plate are in close fit. The discharging diameter of the valve is big, and the discharging rate is quick. Meanwhile, the accumulated material or the accumulated dust on a sealing surface can be scraped off through the opening and the closing of the valve plate. The rotation of the valve plate is flexible, the sealing effect is good, and the service life is long. The utility model is an ideal product which can replace an ash removal ball valve or a bell valve.
Description
The utility model relates to a kind of discharge valve.
Chinese patent literature discloses " a kind of elastic packing ball valve " on April 29th, 92 with notification number CN2103059, its packing holder is located in the releasable connection cover, and with an adjustment ring and one group of adjusting bolt that is located on the connecting sleeve, stage clip is located to be adjusted between ring and packing holder and the adjustment ring, seal ring is located at packing holder the inner, adjust and regulate the position that bolt can change the adjustment ring, with the impacting force of control stage clip packing holder.This valve can adapt to different medium, different operating condition and the wearing and tearing of seal ring are compensated thus.But this valve processing technology difficulty is big.
The purpose of this utility model is to provide a kind of compact structure, manufacturing process is simple, the discharging flow is big discharge valve.The purpose of this utility model is achieved in that it comprises valve body and is fitted to the interior sealing valve plate of valve body and the actuator of driving sealing valve plate keying, described sealing valve plate is made of a supporting body and valve plate, its the two fasten as one, supporting body is connected with valve rod, equipped one valve seat that matches with valve plate on the valve body, valve seat with seal close fit between valve plate.
Described valve plate is the annular disc structure, and supporting body is one of hollow ring structure, the polygon loop configuration of hollow or box structure.The sealing surface of its valve plate and valve base chamber adopts one of the conical surface, plane or sphere, and valve plate, valve rod center line be pair eccentric structures with respect to the center line of valve body.And, between the sealing surface of the two, install seal ring additional in order further to improve the sealing effect of valve plate and valve base chamber.
The technological progress that the utility model is obtained: valve has adopted two eccentric structures, makes valve increase a clamping torque when closing, and improved its sealing effect effectively, and sealing surface does not produce friction when valve opening and closing.By the keying of valve plate, valve plate can be wiped material or the dirt ash that gathers on the sealing surface off simultaneously, and its valve plate rotates flexibly, good seal performance, long service life.The discharging latus rectum of valve is big, thereby the discharging non-resistance, and the discharging amount is big, and discharge rate is fast.Compact overall structure, the volume of this valve are little, in light weight, are the ideal products of a kind of alternative Unloading ball valve or clock valve.
Be that embodiment further describes the utility model below with the accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is Fig. 1 side structure schematic representation.
As shown in Figure 1, 2, the sealing valve plate is fitted in the valve body 1, the sealing valve plate is made of supporting body 2 and valve plate 4, the two constitutes a T-shape annular disc structure, supporting body 2 joins with actuator through valve rod 3, actuator does not provide in the accompanying drawings, can select for use arbitrarily electronic, pneumatic, surge or manual driving mode and present embodiment matches.Be provided with one and be the valve plate 4 of one with it on supporting body 2, its two be a cast steel body.Simultaneously enter the port and be provided with a valve seat 5 that matches with valve plate 4 in the material flow of valve body 1, valve seat 5 fastening being installed on the valve body 1, the sealing surface that valve seat 5 and valve plate are 4 forms ring-like inclined-plane cone-shaped seal structure, and its two junction plane also can be sphere or plane.Valve plate 4 present embodiments are designed to the annular disc structure, and supporting body 2 is designed to the hollow ring structure, and supporting body 2 also can be designed to the polygon disc structure of hollow or box structure and other structural type.Because of the center line of valve plate 4, valve rod 3 adopts a pair of eccentric structure mode with respect to the center line of valve body 1, promptly valve plate 4 and valve rod 3 are assemblied in valve body 1 longitudinal and transverse centerline side respectively.Made valve that higher seal pressure be arranged in the movement process of closing.Valve plate 4 cooperates with valve seat 5, can form a desirable closure tape construction form.In order further to improve the sealing effect of sealing surface, also be provided with seal ring 6 between valve plate 4 and valve seat 5 simultaneously, sealing surface adopts multiple-sealed mode, can make valve reach desirable airtight effect.
Claims (6)
1, a kind of discharge valve, comprise valve body and be fitted to the sealing valve plate in the valve body and drive and seal the actuator that valve plate opens and closes, it is characterized in that described sealing valve plate is made of a supporting body and valve plate, its the two fasten as one, supporting body is connected with valve rod, equipped one valve seat that matches with valve plate on the valve body, valve seat with seal close fit between valve plate.
2, discharge valve according to claim 1 is characterized in that described supporting body is one of the polygon loop configuration of hollow, hollow ring structure or box structure.
3, discharge valve according to claim 1 is characterized in that described valve plate is the annular disc structure.
