Abstract
The utility model discloses a water washing discharge valve which comprises a valve body(4), a valve rod(2), a valve plate(8) and a handwheel(1). Two water receiver ports(7)(3) communicated with a valve plate cavity at the upper part of the valve body are respectively arranged at the left side and the right side of the upper part of the valve body. Flushing pipes(10) are arranged in both water receiver ports and a flushing water drain port(6)is arranged at the bottom of the valve body(4). The discharge valve is mainly characterized in that when opening or closing the valve, the valve port of the valve plate and the bottom of a shutter can be washed through water, so no residue is left between the sealing surfaces or at the bottom of the shutter. Therefore, the shutter can be put in the right plate and abrasion of the sealing surfaces can be reduced, thereby improving the service life of the valve.
Description
Technical field
The utility model belongs to a kind of discharging start-stop device that is applicable to the fluid-solid of enterprises such as oil, chemical industry, relates generally to a kind of water cleaning type discharge valve.
Background technique
The existing oil that is used for, the fluid of enterprises such as chemical industry (mud, mortar, mortar, the bigger fluids of various viscosity such as building stones slurry), solid (powdered materials, particulate matter, lime-ash etc.) discharge valve, its main structure is a valve body, valve port, the bivalve plate, valve rod and handwheel etc., the medium of its discharging all belongs to the fluid and the solid of band finely ground particles and larger particles, owing on the valve mechanism that water dashes is not set specially, above-mentioned medium is all to the valve plate and the sealing valve port face of valve, played serious wearing and tearing and breaking-up effect, long-time use can make the sealing surface of valve plate and valve port damage and form the poorly sealed leakage that causes.When serious, cause whole valve to scrap.
Summary of the invention
The purpose of this utility model provides a kind of rational in infrastructure, water cleaning type discharge valve that can directly wash on valve body.
The purpose of this utility model can adopt following technological scheme to realize: it comprises valve body, valve rod, valve plate and handwheel, be provided with the water inlet that communicates with valve plate chamber, valve body top in the left and right sides, valve body top, be provided with flush pipe in the water saving mouth, the valve body bottom is provided with the flush discharge mouth.
Described flush discharge mouth is provided with closure plate.
The main feature of this discharge valve is, open and closed in can the bottom water of the valve plate of discharge valve, valve port, flashboard be cleaned, make noresidue between sealing surface, the bottom of flashboard does not have retentate, make flashboard put in place, reduced the wearing and tearing of sealing surface, thereby improved the working life of valve.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is right elevations of Fig. 1.
Accompanying drawing 3 is worm's eye views of Fig. 1.
Among the figure: 1, handwheel, 2, valve rod, 3, water inlet, 4, valve body, 5, flange, 6, the flush discharge mouth, 7, water inlet, 8, valve plate, 9, closure plate, 10, flush pipe.
Embodiment
In conjunction with the accompanying drawings, specific embodiment of the utility model is described.
As shown in Figure 1: it comprises valve body 4, valve rod 2, valve plate 8, valve rod 2 and handwheel 1 described water cleaning type unloading board, in being respectively arranged with the water inlet 7 that communicates with valve plate chamber, valve body top and 3, two water savings of water inlet mouthful, the left and right sides, valve body 4 top is provided with flush pipe 10.The valve body bottom is provided with flush discharge mouth 6.Flush discharge mouth 6 is provided with closure plate 9.Be provided with adpting flange 5 at the valve body two ends.
Its working principle is as follows:
The unlatching of valve: valve is in closed condition when the equipment material stock of material stock, the medium of being deposited has been stained with valve plate 8 and valve port, but the sealing surface between valve plate and the valve port does not have medium to be existed, and (thickness of valve plate is the cone structure of upper-wide and lower-narrow type) valve plate and valve port are thrown off when valve opening.It is big more that valve leaves, and the distance between valve plate and the valve port is just far away more, so medium can not cause wearing and tearing and damage to valve plate and valve port, needn't carry out the water cleaning to valve plate and valve port.
Closing of valve: when material stock is unsnatched, during material stock, need close discharge valve once more.When closing discharge valve, at first open the left and right sides flush valve on the discharge valve, water is clean with the medium on valve plate 8 and the valve port (medium that has is also harder than steel) cleaning down by the flush pipe in the water inlet 10, work as valve closing, sealing surface when contacting with valve port, valve plate do not have medium between the sealing surface of valve plate and valve port, so can not damaged the working life of promptly having improved valve.Its two: water falls into the valve plate groove of valve plate bottom along valve plate when the backwash water valve plate, and the medium of being deposited in the valve plate groove is rinsed well in the lump, makes valve plate 8 put in place smoothly, is unlikely to pile with the accurate sealing that influences valve plate and valve port because of valve plate groove medium.
Described discharge valve can be directly installed on the bottom or the middle and lower part of material stock equipment, and the discharge valve exhaust port is connecting tube and directly being disposed in ground or the geosyncline not, and flange is arranged on inlet.
Described discharge valve can be provided with the terminal valve orchid and be directly installed on the import and export pipeline, as the effect of medium in conducting and the cut-out pipe.
