Abstract
The utility model relates to a manual type straight ball valve, mainly applied to oil-gas field, chemical industry, metallurgy industry and pharmaceutical industry, comprising a valve body (1), a valve base (4), a cap (2), a ball (5), and a valve rod (6), which is characterized in that: the valve body (1) comprises a screw, and a check valve (8) is fixed on the screw; a ring groove (7) provided with a seal ring (3) inside is positioned between the cap (2) and the valve body (1); the screw is communicated with the ring groove (7); the seal ring (3) is pressed on the valve base (4). The utility model has the advantages that: the sealing grease can be filled into the ring groove (7) through the check valve (8), and can push the seal ring (3) to press tightly on the valve base (4); when the valve base (4) is worn out, the sealing performance of the valve is degraded, filling the sealing grease through the check valve (8) to push the seal ring (3) and in turn the valve base (4) to press tightly on the ball (5) can improve the sealing performance of the ball valve and prolong the period of usage.
Description
Technical field
The utility model is a kind of straight-through valve, is mainly used in field of engineering technology such as oil gas field, chemical industry, metallurgy, pharmacy, is arranged in the pipeline, is used for controlling a kind of straight-through valve of fluid.It is a kind of manually operated type straight-through valve.
Background technique
At present, in fluid circuit, the straight-through valve of control fluid generally is made up of institutes such as valve body, valve seat, pressure cap, spheroid and valve rods.Spheroid, valve seat, pressure cap are housed in the cylinder shape valve.There is valve seat at the spheroid two ends, and the effect of valve seat is fixedly spheroid and sealing.There is pressure cap the valve seat outer end, fixes and compress valve seat.Valve rod is connected with spheroid, and rotary valve rod drives spheroid and rotates, and reaches the purpose of closing or opening.Sealability must reach usage requirement between spheroid and the valve seat.In use, certainly lead to relative movement and friction between spheroid and the valve seat, the prooving of valve seat reduces sealability, and leakage problem takes place.Ball valve wear and leakage problem is recurrent.For increasing sealability, need adjust pressure cap with the ball valve dismounting down, increase sealing.Adjust sealing like this, increase workload, and influence overall flow.
The model utility content
The purpose of this utility model is: design a kind of ball valve, behind the prooving of valve seat, do not need just can adjust the pressure between valve seat and the spheroid with the ball valve dismounting down, improve the mechanism of sealability.When adjusting sealing like this, reduce workload, and do not influence ball valve work and overall flow.
The utility model is achieved in that by institutes such as valve body, valve seat, pressure cap, spheroid and valve rods to be formed.Spheroid is housed in the cylinder shape valve.There is valve seat at the spheroid two ends.There is the pressure cap fixed valve base valve seat outer end.Valve seat, pressure cap, ball centre have fluid passage.Valve rod is connected with spheroid.It is characterized in that: screw is arranged on the valve body, be fixed with one-way valve on the screw.Between pressure cap and the valve body circular groove is arranged, seal ring is arranged in the circular groove.Screw communicates with circular groove.Seal ring is pressed on the valve seat.One-way valve can adopt spherical one-way valve, also can adopt the taper one-way valve.
Effect of the present utility model: can annotate seal gease by one-way valve in circular groove, seal gease promotes seal ring and compresses valve seat.When valve seat weares and teares, when the sealability of ball valve reduces, annotate seal gease again by one-way valve, seal ring promotes valve seat and compresses spheroid, keeps the sealability of spheroid and valve seat.Needn't dismantle ball valve like this and adjust pressure cap, just can under the situation that does not influence whole flow process, improve the sealability of ball valve, prolong the working life of ball valve.
Description of drawings
Illustrations 1 is the generalized section of a greasing seal feed-through valve.Be an embodiment of the present utility model.
Sequence number corresponding components in the accompanying drawing is: 1-valve body, 2-pressure cap, 3-seal ring, 4-valve seat, 5-spheroid, 6-valve rod, 7-circular groove, 8-one-way valve, 9-one-way valve valve body, 10-spring, 11-ball, 12-spool, 13-plain cushion, 14-protective cap.
Embodiment
Embodiment 1: with latus rectum is that 100 millimeters greasing seal feed-through valve is an example, and the utility model is further specified.Valve body (1) is to adopt casting to make, and two ends have and the pipeline flange connecting, and the internal diameter of valve body (1) is 180 millimeters.Valve seat (4) adopts poly-tetrafluoro to make.Spheroid (5) is housed in the cylinder shape valve (1), and the radius of spheroid (5) is 90 millimeters.Respectively there is a valve seat (4) at spheroid (5) two ends.Respectively there is a pressure cap (2) fixed valve base (4) valve seat (4) outer end.The fluid passage aperture at valve seat (4), pressure cap (2), spheroid (5) center is 100 millimeters.Be connected between valve rod (6) and the spheroid (5).Two screws are arranged on the valve body (1), fix an one-way valve (8) on the screw respectively.One-way valve (8) adopts spherical one-way valve (8).Sealing plain cushion (13), ball (11), helical spring (10) are arranged in the one-way valve spool (12).Circular groove (7) width between pressure cap (2) and the valve body (1) is 20 millimeters, and U RunddichtringO (3) is arranged in the circular groove (7), and the internal diameter of U RunddichtringO (3) is 140 millimeters, and external diameter is 180 millimeters, highly is 20 millimeters.Screw communicates with circular groove (7).Seal ring (3) is pressed on the valve seat (4).When valve seat (4) is worn, when the sealability of ball valve reduces, inject seal gease by one-way valve (8) in circular groove (7), seal gease promotes seal ring (3) and compresses valve seat (4), valve seat (4) compresses spheroid (5), keeps the sealability of spheroid (5) and valve seat (4).Needn't dismantle ball valve like this, just can under the situation that does not influence whole flow process, improve the sealability of ball valve.
