Abstract
A spherical valve with a built-in hydraulic driver belongs to the technical field of manufacture of valves. The spherical valve comprises a valve body, a valve cap, a valve seat ring mounted in the valve body, a sphere, a valve rod connected with the sphere, and a driver for driving the valve rod. The spherical valve is characterized in that the driver comprises a hydraulic cylinder arranged on the valve body, tooth racks which are provided with O-shaped seal rings at two ends and are mounted in the hydraulic cylinder, and a gear mounted on the valve rod and meshed with the tooth racks. The hydraulic cylinder is directly processed on the valve body; the valve driver is formed by the hydraulic cylinder, the gear and the tooth racks together; and the switching on-off of the valve can be controlled through hydraulic oil. In addition, the driver is arranged in the valve body, so that the valve with small volume is suitable for the places with narrow space.
Description
Technical field
The utility model relates to the improvement of ball valve.Belong to technical field of valve manufacturing.
Background technique
Present ordinary ball valve mainly is made of valve body, valve gap, the driver that is installed in seat ring, spheroid, the valve rod that is connected with spheroid and actuate valve stem in the valve body, its drive part all is located at the outside of valve body, is installed on the valve body with other links such as bolt, supports.Complex structure and bulky needs very big installing space, just can't use in the restricted place of some installing spaces.Especially in deep earth sampling, valve need place with hollow drill in, be put into seabed a series of actions such as finish that sampling, valve closing are mentioned again with drilling rod, the external valve of this driver can't be installed and be used at all.
The model utility content
The purpose of this utility model is: design a kind of built-in ball valve of hydraulic unit driver of new structure, be used to solve the usage requirement under the restricted condition of installing space.
The formation of the ball valve that this hydraulic unit driver is built-in comprises valve body, valve gap, is installed in the driver of seat ring, spheroid, the valve rod that is connected with spheroid and actuate valve stem in the valve body, it is characterized in that at described driver by being opened in oil hydraulic cylinder on the valve body, being installed in the tooth bar of its two ends band O-ring seals in the oil hydraulic cylinder and being installed in being constituted with this tooth bar meshed gears on the valve rod.
When oil hydraulic cylinder when wherein an end enters hydraulic oil, oil pressure promotes the tooth bar motion, and the rack drives gear rotates, the gear driven valve rod, and valve rod drives spheroid, thereby realizes the open and close action of valve.
The utility model is by directly processing an oil hydraulic cylinder on valve body, constitute the driver of valve, the open and close that come control valve by hydraulic oil with gear, tooth bar.Because driver is arranged in the valve body, thereby makes the valve volume small and exquisite, not limited by the mounting point.Being suitable for narrow and small place, space uses.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
Description of drawings
Fig. 1 is the structural representation of present embodiment
Fig. 2 is the A-A partial view of Fig. 1
Embodiment
Referring to Fig. 1～2, the formation of the ball valve that this hydraulic unit driver is built-in comprises valve body 8, valve gap 9, is installed in the driver of seat ring 4, spheroid 5, the valve rod 7 that is connected with spheroid 5 and actuate valve stem 7 in the valve body 8, and described driver is by being opened in oil hydraulic cylinder 11 on the valve body 8, being installed in the tooth bar 3 of its two ends band O-ring seals 2 in the oil hydraulic cylinder 11 and being installed in being constituted with these tooth bar 3 meshed gears 6 on the valve rod 7.Oil hydraulic cylinder 11 is installed oil transportation joint 1 and 10 and is constituted by directly processing a hole as cylinder body on valve body 8 at its two ends.
When oil transportation joint 1 enters hydraulic oil, oil pressure promotes tooth bar 3 motions, and tooth bar 3 driven gears 6 rotate, and gear 6 drives valve rods 7 and rotates, and valve rod 7 drives spheroids 5 and rotates, thereby realizes the action of valve closing.Otherwise when oil transportation joint 10 entered hydraulic oil, oil pressure promoted tooth bar 3 motions, and 6 revolutions of tooth bar 3 driven gears also drive valve rod 7 and rotate, and valve rod 7 drives spheroids 5 and rotates, thereby realizes the action of valve opening.
Claims (1)
1. ball valve that hydraulic unit driver is built-in, comprise valve body, valve gap, be installed in the driver of seat ring, spheroid, the valve rod that is connected with spheroid and actuate valve stem in the valve body, it is characterized in that at described driver by being opened in oil hydraulic cylinder on the valve body, being installed in the tooth bar of its two ends band O-ring seals in the oil hydraulic cylinder and being installed in being constituted on the valve rod with this tooth bar meshed gears.
