Abstract
The utility model relates to gate valves, and discloses a hydraulic gate valve. The hydraulic gate valve is characterized in that an oil cylinder piston rod of an oil cylinder placed on the top of a valve body is connected with a valve element in the valve body, a water inlet hole and a water outlet hole are formed in two sides of the valve body respectively, a valve seat is connected with the valve body through screws, a first O-shaped seal ring is arranged between the valve seat and the valve body, a seal ring is arranged between the valve element and the valve body, an end cap is in a shape of a step, a small end of the end cap extends into the seal ring in the valve body, and a big end of the end cap is connected to the valve body through screws. According to the hydraulic gate valve, a plurality of threaded connectors in an original valve are removed, structure is simple, the valve body and the valve seat are connected through the screws, therefore, disassembly and maintenance are convenient, seal performance of the valve seat and the valve body and the seal performance of the valve element and the valve body are reliable, and service life is long.
Description
Technical field
The utility model relates to gate valve.
Background technique
Hydraulic sluice valve is the break-make of controlling high-pressure oil passage, water route, the unlatching of gate valve, close by hydraulic jack and control, as shown in Figure 2, oil cylinder 1 is connected with spool 9 in the valve body by liquid joint 2, nut 3 is threaded with spool guide sleeve 4 usefulness, and blind nut 5 uses in the environment of water by the u-shape seal ring 7 on gland 6 pressed spools 9, reliability is inadequate, easily reveals.Sealed by ' 0 ' RunddichtringO 8 and ' 0 ' RunddichtringO 11 between valve seat 11 and the valve body 12, lean on the complex structure of face sealed valve between spool 9 and the valve seat 10, after valve seat 10 is through long-time the use, sealing surface easy damaged with spool 9, affect sealability and cause valve normally to use, and produce leakage after valve seat 10 and valve body 12 corrosions, the valve seat 10 of corrosion is difficult to take out from valve body 12 to be changed, and between nut 5 and the valve body 12 for fine thread is connected, the dismounting difficulty is large after the corrosion.
Summary of the invention
The purpose of this utility model is to provide: hydraulic sluice valve, it be a kind of simple in structure, sealing is reliable, the valve of long service life.
The technical solution of the utility model realizes as follows:
The utility model comprises valve seat, spool, valve body, oil cylinder, oil cylinder is at the top of valve body, spool in cylinder piston rod on the oil cylinder and the valve body is connected, one side of valve body has water intake, and opposite side has water outlet, and valve seat and valve body are connected by screw, the sealing of ' 0 ' RunddichtringO is arranged between valve seat and the valve body, between spool and the valve body seal ring is arranged, the small end of rank shape end cap extend on the interior seal ring of valve body, and the large end of end cap is connected by screw on valve body.
The utility model is simple in structure, has saved many threaded connectors of former valve, and valve body is connected by screw with valve seat, and convenient disassembly is convenient to maintenance, realizes sealing by metal covering between its spool and the valve seat, and its sealing is reliable, long service life.

Fig. 2 is former hydraulic pressure gate valve structure schematic diagram.
Embodiment
Referring to accompanying drawing embodiment, the utility model is described in further detail.
Among Fig. 1, oil cylinder supporting frame 11 is at the top of valve body 10, oil cylinder 6 is arranged on the oil cylinder supporting frame, cylinder piston rod 5 on the oil cylinder 6 is connected with spool 2, spool 2 enters installation from the top of valve body 10, one side of valve body 10 has water intake 3, opposite side has water outlet 4, valve seat 1 is connected with valve body 10 usefulness screws, and 9 sealings of ' 0 ' RunddichtringO are arranged between valve seat 1 and the valve body 10, lets out with in preventing, seal ring 8 sealings are arranged between spool 2 and the valve body 10, end cap 7 is stepped shape, and the small end of end cap 7 extend into valve body 10 interior press seal circles 8, and the large end of end cap 7 is connected on the valve body 10 at the top of valve body 10 and with screw.During work, oil cylinder 6 makes spool 2 rise, descend under the promotion of hydraulic jack, moves downward to the bottom when oil cylinder makes spool 2, disconnects between water intake 3 and the water outlet 4, and after oil cylinder 6 made spool 2 move up to the top, water intake 3 was communicated with water outlet 4.
