Abstract
The utility model relates to a fixed ball valve which is composed of a valve body, a ball body, a gland, a handle, a regulating sleeve and a plate spring. The utility model is characterized in that a ball hole is arranged on the ball body, and a lower shaft and an upper shaft are arranged on the ball body which is fixed in the valve body through a bearing, the gland and screws; a sealing ring is sheathed on the upper shaft, and a locating block is covered on the upper shaft. The handle is installed on the end head of the upper shaft, and a sealing ring for the valve seat, the plate spring and the regulating sleeve are orderly arranged at both sides of the ball body. The utility model has the advantages of simple structure, small size, light weight, reliable sealing performance, small fluid resistance, convenient operation, flexible adjustment and convenient maintenance. The utility model is convenient to remotely control.
Description
The utility model relates to a kind of Fixed ball valve, belongs to valve type.
At present, develop rapidly along with the construction of industries such as China's oil, chemical industry, electric power, aviation, various valves are enriching the various demands that people's production, scientific research, life are satisfied in market, but it is excessive that the existing valve that generally uses exists boundary dimension, unlatching is wasted time and energy, and fluid resistance is big, and seal ring is easy to wear, poor sealing performance, deficiencies such as maintenance difficult.The Float ball valve of rising in recent years is though its volume is little in light weight, easily manufactured, fluid resistance is little, but has all passed to the exit seal circle because spheroid bears the load of working medium, can only realize one-way sealing, and the outlet end sealing surface is easy to wear, and working life is short.In addition, Float ball valve also has a fatal shortcoming, and immediate shipment timing pretightening force is wayward, needs to adjust with the different pad of thickness, assembles cumbersomely, and it is bigger to operate moment of torsion simultaneously, the gas of requiring great effort very much.
The purpose of this utility model is to design a kind of simple in structure, and is easy to operate, opens and closes rapidly, and a kind of Fixed ball valve of reliable sealing is to overcome existing deficiency.
The purpose of this utility model is to realize like this, it is mainly by valve body (1), spheroid (2), gland (3), handle (4), adjustment sleeve (5) and leaf spring (6) are formed, it is characterized in that: spheroid (2) is provided with ball hole (8), lower shaft (9) and last axle (13) are arranged on the spheroid (2), spheroid (2) is by bearing (7), gland (3) and screw (14) are fixed in the valve body (1), be set with seal ring (12) on the last axle (13) and buckle closure has positioning block (10), on the termination of last axle (13) handle (4) is installed, in the valve body (1) of spheroid (2) both sides valve seat insert (11) is installed successively, leaf spring (6) and adjustment sleeve (5).
The utility model compared with prior art, it is simple in structure, volume is little, and is in light weight, sealing is reliable, fluid resistance is little, and is easy to operate, regulates flexibly, as long as complete switch revolves turn 90 degrees, be convenient to distant control, applied widely, easy to maintenance, be a kind of novel Fixed ball valve.
Below in conjunction with drawings and Examples the utility model is further specified:
Accompanying drawing is the whole sectional structure schematic representation of the utility model.
Wherein: 1, valve body, 2, spheroid, 3, gland, 4, handle, 5, adjustment sleeve, 6, leaf spring, 7, bearing, 8, the ball hole, 9, lower shaft, 10, positioning block, 11, valve seat insert, 12, seal ring, 13, go up axle, 14, screw.
Referring to accompanying drawing: the utility model it mainly by valve body 1, spheroid 2, gland 3, handle 4, adjustment sleeve 5 and leaf spring 6 are formed, spheroid 2 is provided with ball hole 8, advancing of the aperture in the utility model ball hole 8 and valve body, outlet is designed to and the pipeline equal diameter, make fluid resistance little, lower shaft 9 and last axle 13 are arranged on the spheroid 2, spheroid 2 is by bearing 7, gland 3 and screw 14 are fixed in the valve body 1, be set with bearing 7 on the lower shaft 9, the bottom of last axle 13 is set with bearing 7, the top of last axle 13 is set with seal ring 12 and buckle closure has positioning block 10, on the termination of last axle 13 handle 4 is installed, in the valve body 1 of spheroid 2 both sides valve seat insert 11 is installed successively, leaf spring 6 and adjustment sleeve 5, and valve seat insert 11 is pressed on the sphere of spheroid 2 by certain pretightening force, so just guaranteed, the two way sealed of outlet, realized zero leakage, owing to do not produce mobile behind spheroid 2 pressurizeds, so sealed at both ends surface wear of the present utility model is even, and can realize automatic compensate for wear amount by leaf spring 6 elastic elements after the wearing and tearing, improved working life of the present utility model, simultaneously owing to all be provided with bearing 7 on lower shaft 9 and the last axle 13, so reduced the operation moment of torsion, made opening and closing more laborsaving.
