Abstract
The utility model relates to a ball valve with good sealing performance and convenient installation and disassembly, which is used for the slurry conveying. The ball valve which publicly known is mainly composed of an end cover, a sealing device, an angular-motion actuating mechanism, a ball body, a valve rod, a valve body and a press cover. The utility model is characterized in that an elastic ring body (2) is arranged between the ball body (4) and the end cover (1), the seal lip (20) of the ring body (2) is connected with the ball body (4). A-shaped cavity (19) is arranged in the ring body (2), and the inner surface (24) of the ring body (2) is provided with an opening.
Description
The utility model relates to a kind of ball valve, particularly carries about slurry and uses ball valve.
At present, known ball valve mainly is made up of end cap, seal arrangement, angular motion actuator, spheroid, valve rod, valve body, gland.Be used for forming by seal ring, thrust spring with sealing mechanism between spheroid and the end cap, or form by seal ring, fastening piece.The problem that they exist is: sealing effect is bad, installing/dismounting inconvenience etc.
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art and new-type ball valve that a kind of good airproof performance, easy installation and removal are provided.
The purpose of this utility model can reach by following measure: the known ball valve that is used for the slurry conveying, mainly form by end cap, seal arrangement, angular motion actuator, spheroid, valve rod, valve body, gland.Improvements of the present utility model are: elastic annular body (2) is installed between spheroid (4) and end cap (1), the sealing lip (20) of this ring bodies (2) joins with spheroid (4), establish special-shaped chamber (19) in this ring bodies (2), this ring bodies (2) internal surface (24) has mouth.
The purpose of this utility model can also reach by following measure: curved of the face that sealing lip (20) and spheroid (4) join.
The purpose of this utility model can also reach by following measure: the mouth that ring bodies (2) internal surface (24) is opened is mouth ringwise.
The purpose of this utility model can also reach by following measure: a side (23) of ring bodies (2) is the plane, and the internal surface (24) that joins with face (23) is the cylndrical surface.
The purpose of this utility model can also reach by following measure: the outer surface (22) of ring bodies (2) is the cylndrical surface, is curved surface (21) between the outer surface (22) of ring bodies (2) and sealing lip (20).
The purpose of this utility model can also reach by following measure: curved surface (21) is conical surface.
The purpose of this utility model can also reach by following measure: be curved surface (25) between cylndrical surface (22) and side (23).
The purpose of this utility model can also reach by following measure: curved surface (25) can be an arc shaped surface.
The drawing of accompanying drawing is described as follows:
Fig. 1, structural representation of the present utility model
Fig. 2, the worm's eye view of elastic annular body (2)
Fig. 3, the main pseudosection of elastic annular body (2)
Fig. 4, the plan view of elastic annular body (2)
1, end cap 2, elastic annular body 3, both-end seal ring 4, spheroid 5, valve body 6, lower valve rod 7, O RunddichtringO 8, following lining 9 back-up rings 10, anti-wearing liner 11, anti-wearing liner 12, trim ring 13, O RunddichtringO 14, gland 15, half dollar head flat key 16, upper valve rod 17, last lining 18, derailing switch 19, special-shaped chamber 20, sealing lip 21, conical surface 22, cylndrical surface 23, one side 24 of ring bodies (2), the cylndrical surface 25 of ring bodies (2), the arc shaped surface of ring bodies (2).
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
10 anti-wearing liners, 11 anti-wearing liners all can adopt cast stone materials such as basalt to make.Elastic annular body (2) can polyurethane etc. has elasticity and wear-resisting material is made by resembling.Curved of sealing lip (20) or similar curved that ring bodies (2) and spheroid (4) join, establish ring-type abnormity chamber (19) in the ring bodies (2), ring bodies (2) internal surface (24) is the cylndrical surface and has annular port, one side (23) of ring bodies (2) is the plane, the outer surface (22) of ring bodies (2) is the cylndrical surface, between the outer surface (22) of ring bodies (2) and sealing lip (20), be similar curved such as circular cone, curved surface such as curved between cylndrical surface (22) and side (23).All the other are known technology, so seldom narration.
The utility model compared with prior art has following advantage: owing between spheroid (4) and end cap (1) elastic annular body (2) has been installed, the sealing lip (20) of ring bodies (2) joins with spheroid (4), establish special-shaped chamber (19) in the ring bodies (2), ring bodies (2) internal surface (24) has mouth, therefore, in the time of in slurry passes through runner, slurry can enter in the special-shaped chamber (19) that has mouth, the sealing lip (20) of elastic annular body (2) and side (23) produce pressure, sealing lip (20) is sealed mutually with spheroid (4) better, ring bodies (2) side (23) is sealed mutually with end cap (1) better, thereby reach the purpose of good sealing effect, again because elastic annular body (2) is an integral body, so installing/dismounting is all convenient.
