Abstract
The utility model relates to a cartridge valve disassembling device which is characterized by comprising a threaded rod. A first nut and a second nut are arranged at the top of the threaded rod, the bottom of the threaded rod is in a wedge shape, the threaded rod is sequentially sleeved with an inner expanding sleeve and a valve element sleeve or a valve sleeve expanding sleeve, a bearing plate is connected with a valve sleeve through a valve element bearing sleeve, or connected with a valve block through a valve sleeve bearing sleeve, the threaded rod penetrates through the bearing plate, the outer diameter of the valve element sleeve corresponds to the inner diameter of the valve element, or the outer diameter of the valve sleeve expanding sleeve corresponds to the inner diameter of the valve sleeve, and the bottom of the threaded rod, the inner expanding sleeve and the valve element sleeve or the valve sleeve expanding sleeve are arranged in a hole of the valve element to be disassembled or the valve sleeve to be disassembled. According to the cartridge valve disassembling device, the valve elements and the valve sleeves of cartridge valves in the specifications ranging from DN16 to DN160 are disassembled by replacing the expanding sleeves with different outer diameters and the supporting sleeves with different diameters; by means of the cartridge valve disassembling device, the labor intensity of workers can be further lowered, and efficiency can be improved.
Description
Technical field
The utility model belongs to hydraulic control system, particularly a kind of hydraulic control system with inserted valve.
Background technology
Inserted valve is arranged in valve piece, and valve pocket and valve piece fit clearance are smaller, and is radially having O-ring seals, and it is in conjunction with tightr, and the detachable maintaining of valve pocket is difficult for, and particularly, for the inserted valve of large latus rectum, the dismounting of valve pocket is difficulty especially; In addition due to spool and valve pocket fit clearance very little, if both are unexpected stuck, be difficult to be separated.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of inserted valve provision for disengagement, to overcome the defect existing in prior art.
The technical solution of the utility model is: a kind of inserted valve provision for disengagement, is characterized in that: comprise screw rod, screw rod top is provided with the first nut and the second nut, and screw rod bottom is wedge shape, and on screw rod, cover has inner expanding sleeve, valve core housing or valve pocket ringfeder successively; Support plate is connected with valve pocket or valve piece respectively by spool splicing sleeve or valve pocket splicing sleeve, and screw rod is through support plate; The external diameter of valve core housing or valve pocket ringfeder is corresponding with the internal diameter of spool or valve pocket respectively, and screw rod bottom, inner expanding sleeve and valve core housing or valve pocket ringfeder are placed in the spool or valve pocket hole that will dismantle.
Described support plate is between the first nut and the second nut.
Technique effect of the present utility model is:
The utility model utilizes expansion sleeve tensioner spool (or valve pocket), nut is fixed on valve pocket (or valve piece) by gripper shoe and support set, drive wedge shape screw rod to move upward by rotating nut, thereby after making tensioner tight, wedge shape screw rod moves upward together with spool (or valve pocket), depart from valve pocket (or valve piece), realize the dismounting of spool (or valve pocket); By changing ringfeder and the support set of various outer diameter, realize inserted valve spool to DN16-DN160 all size and the dismounting of valve pocket; Use the utility model, can also reduce labor strength, raise the efficiency.

The specific embodiment
The utility model belongs to hydraulic control system, particularly a kind of hydraulic control system with inserted valve.Referring to Fig. 1 and Fig. 2, the concrete structure of a kind of inserted valve provision for disengagement that the utility model relates to is:
The external diameter of valve core housing 2 or valve pocket ringfeder 11 is corresponding with the internal diameter of spool 9 or valve pocket 8 respectively, and screw rod 1 bottom, inner expanding sleeve 3 and valve core housing 2 or valve pocket ringfeder 11 are placed in the spool 9 or valve pocket 8 holes that will dismantle.
Known by Fig. 1, in the time of dismounting inserted valve spool and valve pocket, spool 9 and valve pocket 8 are stuck, wedge shape screw rod 1, inner expanding sleeve 3 and the valve core housing 2 corresponding with spool 9 are put into hole, fastening the first nut 4, inner expanding sleeve 3 is spreading under the effect of wedge shape screw rod 1, and drive valve core housing 2 spreadings, valve core housing 2 and spool 9 endoporus are combined closely, make wedge shape screw rod 1, inner expanding sleeve 3, valve core housing 2 and spool 9 become one, then spool splicing sleeve 7 is placed on valve pocket 8, wedge shape screw rod 1 is through support plate 6 and screw the second nut 5, by rotating the second nut 5, wedge shape screw rod 1 is moved upward, thereby drive inner expanding sleeve 3, valve core housing 2 and spool 9 are upwards, reach the object that separates spool 9 and valve pocket 8.
Known by Fig. 2, in the time of dismounting valve piece and inserted valve valve pocket, the valve pocket 8 of inserted valve is arranged in valve piece 10, wedge shape screw rod 1, inner expanding sleeve 3 and the valve pocket ringfeder 11 corresponding with valve pocket 8 are put into hole, fastening the first nut 4, inner expanding sleeve 3 is spreading under the effect of wedge shape screw rod 1, and drive valve pocket ringfeder 11 spreadings, valve pocket ringfeder 11 and valve pocket 8 endoporus are combined closely, make wedge shape screw rod 1, inner expanding sleeve 3, valve pocket ringfeder 11 and valve pocket 8 become one, then valve pocket splicing sleeve 12 is placed on valve piece 10, wedge shape screw rod 1 is through support plate 6 and screw the second nut 5, by rotating the second nut 5, wedge shape screw rod 1 is moved upward, thereby drive inner expanding sleeve 3, valve pocket ringfeder 11 and valve pocket 8 are upwards, reach the object that separates valve pocket 8 and valve piece 10.
The parts that the present embodiment does not describe in detail and structure belong to well-known components and common structure or the conventional means of the industry, here not narration one by one.
