As a preferred scheme, the double-end stud sequentially penetrates through the driving support, the support rod, the middle cover and the valve body wall at the corresponding position from top to bottom, and nuts are arranged at two ends of the double-end stud to realize locking.

Preferably, the driving device is an air cylinder.

Preferably, the cylinder is fixed to the driving bracket by at least three stud bolts.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model discloses structurally optimizing at traditional integral type mud valve, with traditional integral type structure, designing into the sectional type and connecting, being about for valve body and drive arrangement and separating through the connecting piece and coming. Therefore, the functions of all parts on the valve device are more definite, and the mutual interference between the driving device and the valve body can be effectively avoided. And, the setting of connecting piece has solved traditional mud valve from essence, and when drive arrangement and valve body lug connection, the back takes place to leak in valve rod packing seal department, and muddy water directly gets into drive arrangement and produces the corrosion problem. And the clearance has again between well lid in the connecting piece and the drive support, even valve rod filler leakage appears in the mud discharging device use, also can discover and can carry out maintenance processing on line the very first time, avoided needing to change and handle separately behind the whole mud discharging device, both alleviateed maintainer's work load, also prolonged the online life of mud discharging device.

Detailed Description

The present invention will be further described with reference to the following description and examples, which include but are not limited to the following examples.

The purpose of this embodiment is in order to provide a use more reliably and life longer row mud device. Referring to fig. 1, the sludge discharge device is a sectional type pneumatic sludge discharge device, and mainly comprises a cylinder, a sectional connecting piece and a valve body, wherein the cylinder is isolated from the valve body by the sectional connecting piece. Particularly, the cylinder that row's mud device of this embodiment chose for use is as drive arrangement, and the structure of cylinder is the same basically with current valve cylinder structure, all includes structures such as piston bush 10, piston 11 and upper cover 13, and the difference only lies in, and the cylinder control of this embodiment uses two four-way solenoid valve, adopts 24V direct current to get into for long-range compressed air and drives actuating cylinder, drives actuating cylinder and lets in compressed air, and the piston reciprocates in the cylinder body, drives the valve rod and reciprocates, realizes the switch of valve. In addition, the appearance of the piston sleeve is also adjusted adaptively so as to facilitate installation, specifically, in the embodiment, the upper cover 13 above the piston sleeve 10 is enlarged and is fixed on the segmented connecting piece through at least three stud bolts so as to realize the fixation of the cylinder and ensure the installation stability of the cylinder; also, since the upper end of the valve stem 4 is fixed to the piston 11, the present embodiment provides a split cap 12 at the end of the valve stem above the piston 11 to prevent the valve stem from being separated from the piston.

Further, the valve body 1 of this embodiment is the same with the valve body structure of current row mud device to the position and the mounting means of valve rod 4 are also basically the same, and valve rod 4 lower extreme meets with valve clack 2 through O shape circle 3. Furthermore, the sectional connecting piece is simple in structure, but the arrangement is ingenious. In detail, the segment joint comprises a middle cover 7 fixed on the valve body 1, a driving bracket 8 fixed below the cylinder, and a stay bar arranged between the middle cover and the driving bracket for supporting the driving bracket. Wherein, the effect of vaulting pole is lid 7 and drive support 8 separation in will to have the clearance between lid 7 and the drive support 8 in making, so, be about to valve body and cylinder separation, the upper end of valve rod 4 links to each other with piston 11 in the cylinder after passing through in proper order lid 7 and the middle part of drive support 8 promptly. When the valve rod filler of row's mud device appeared leaking in the use, even muddy water toward leaking outward, can not directly get into inside the cylinder yet, can prevent muddy water to the inside corrosion of cylinder, solve the cylinder and get into muddy water and produce the puckery and muddy water entering solenoid valve corrosion problem, the life of extension mud valve. And, compare in driven mud valve, because this embodiment segmentation connecting piece has the clearance, can discover to leak at the very first time (traditional mud valve can not discover very first time, but just can discover after the valve breaks down and closes, then the disintegration is handled) to can online maintenance processing, in order to avoid leaking the increase of quantity, so, because discovery in time, can reduce the damage degree of mud discharging device, and then reduce maintainer's work load. For the convenience of on-line operation, the gap between the middle cap 7 and the driving bracket 8 is preferably between 130mm and 170 mm.

In addition, the middle cover 7 can be directly fixed on the valve body 1 through the stud 5 and the nut 6, and the specific fixing operation is very simple and is not described in detail herein. Except this kind of fixed mode, this embodiment can also with stud 5 from last down run through drive support 8, vaulting pole, well lid 7 and the valve body wall setting that corresponds the position in proper order, the stud both ends are equipped with nut 6, in order to realize locking, adopt this kind of mode fixed, can make the fixed stability of segmentation connecting piece better, and stud 5 hides in the vaulting pole, also can not increase the spliced pole quantity between lid 7 and the drive support 8, influences the maintenance operation.
