Abstract
The utility model discloses a manual floating ball valve, which comprises a main valve body, a side valve body, a ball body and a valve stem, wherein the main valve body is fixedly connected with the side valve body through a bolt, and the ball body is positioned in a sealed cavity of the main valve body and the side valve body; one end of the valve stem penetrates through a mounting hole of the main valve body to extend out, and the other end of the valve stem is fixedly connected with the ball body in the valve body; valve seats are respectively arranged on inclined planes in the main valve and the side valve body, and each valve seat is a double-inclined plane elastic sealing ring or V-shaped groove elastic sealing ring; one end of the valve stem extending out of the mounting hole of the main valve body is connected with a handle, and a packing cylinder is arranged in the mounting hole of the main valve body, through which the valve stem penetrates; packing is filled in the packing cylinder to play a role of stabilizing and sealing the valve stem, and a packing gland is arranged above the packing cylinder; and the packing cylinder is fixedly connected with the packing gland through a bolt, and a gasket is arranged on a joint face between the main valve body and the side valve body. According to the manual floating ball valve provided by the utility model, the safety performance is improved, the sealing performance of the ball valve is enhanced, and the work efficiency is also improved.
Description
Technical field
The utility model relates to a kind of ball valve, especially relates to a kind of manual floating ball valve.
Background technique
Manual ball valve is widely used in the automation control system of the industrial departments such as papermaking, petrochemical industry, chemical industry, metallurgy, electric power, environmental protection, oil, light industry, is used for the occasions such as sampling, blowing, flushing, blowdown.Traditional manual floating ball valve multiselect macromolecule polymeric material, its material is softer, if manually floating ball valve is wanted the seal pressure that reaches certain, open and close torque is increased, this ball valve easily makes ball valve damage when pressure medium is excessive, can bring scarcely potential safety hazard to construction; When pressure medium was less, pressure medium can not be guaranteed reliable sealability again, and can decay after the long-term use of pretightening force, can cause sealability to descend.
Summary of the invention
For above-described the deficiencies in the prior art, the utility model discloses a kind of manual floating ball valve, Safety performance is high, and good seal performance.
A kind of manual floating ball valve, comprise main valve body, side valve body, spheroid, valve rod, wherein main valve body and side valve body are bolted to connection, spheroid is positioned at the seal chamber that main valve body is connected with the side valve body, the mounting hole that one end of valve rod passes main valve body reaches the outside, spheroid in the other end and the valve body is fixedly connected with, and described inclined-plane in main valve body and side valve body is respectively equipped with valve seat.
Wherein valve seat is double inclined plane elastic seal ring or V-type groove elastic seal ring.This structure can utilize manifold pressure to promote spheroid, helps sealing.
Further, valve rod stretches out an end connecting handle of main valve body mounting hole.
Wherein be provided with the filler cylinder in valve rod passes the hole of main valve body, the filler of packing in the filler cylinder can play effect firm and sealing to valve rod.
Further, filler cylinder top is provided with Gland, and filler cylinder and Gland are bolted to connection.
Further, between the mating face of main valve body and side valve body, be provided with sealing gasket.
Above-mentioned structure, when pressure medium hour, seal ring and spheroid area of contact are less, therefore larger seal pressure is arranged, guarantee reliable sealing; When pressure medium was larger, the area of contact of seal ring and spheroid increased, therefore seal ring can bear larger medium thrust and can not damage.
Manual floating ball valve provided by the utility model improves Safety performance, has also strengthened the sealability of ball valve simultaneously, and working efficiency has also had raising.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1 is main valve body, and 2 is the side valve body, and 3 is spheroid, and 4 is handle, and 5 is valve rod, and 6 is valve seat, and 7 is the filler cylinder, and 8 is Gland, and 9 is sealing gasket.
Embodiment
As shown in Figure 1, it is the preferred embodiment of a kind of manual floating ball valve of the utility model, comprise main valve body 1, side valve body 2, spheroid 3, valve rod 5, wherein main valve body 1 and side valve body 2 are bolted to connection, spheroid 3 is positioned at main valve body 1 and is connected the seal chamber that connects with the side valve body, the mounting hole that one end of valve rod 5 passes main valve body 1 reaches the outside, and the interior spheroid 3 of the other end and valve body is fixedly connected with, and described inclined-plane in main valve body 1 and side valve body 2 is respectively equipped with valve seat 6.
Wherein valve seat 6 is double inclined plane elastic seal ring or V-type groove elastic seal ring, and this structure can utilize manifold pressure to promote spheroid, helps sealing.Valve rod 5 stretches out an end connecting handle 4 of main valve body 1 mounting hole.
Wherein be provided with filler cylinder 7 in valve rod 5 passes the hole of main valve body 1, the filler of packing in filler cylinder 7 can play effect firm and sealing to valve rod 5.Filler cylinder 7 tops are provided with Gland 8, and filler cylinder 7 is bolted to connection with Gland 8.Between the mating face of main valve body 1 and side valve body 2, be provided with sealing gasket 9.
The utility model is when sealing, handle with sleeve 4 makes valve rod 5 drive spheroid 3 and rotates, the sealing surface of the sealing surface of spheroid 3 and valve body media passage contacts and reaches sealing, this moment medium thrust so that spheroid 3 move to the direction identical with medium thrust, the inclined-plane upper valve base 6 that is separately positioned in main valve body 1 and the side valve body 2 can produce a cushion effect to spheroid 3, and identical with the phase-contact surface of spheroid 3, strengthened sealability.
Above-described structure is preferred embodiment of the present utility model, and being equal to of the structure of this product replaced to reach identical effect, and perhaps the art personnel are apparent, all should belong to protection domain of the present utility model.
