Abstract
The utility model discloses a novel ball valve, including valve body and valve rod, be equipped with ellipse spheroid in the valve body, ellipse spheroid passes through the valve rod and links to each other with the valve body, valve rod top rigid coupling fixing base, valve rod lower part rigid coupling valve body seat, the valve body seat links firmly with the valve body inner chamber, be equipped with the sealing washer between ellipse spheroid and valve body, ellipse spheroid goes up the rigid coupling has a plurality of arris pieces, the arris piece is parallel to each other. The ball valve of this structure will be oval design for the ellipse circular spherical body, its both sides with the contact surface that the medium contacted with original round valve plate change to resistance when the reduction ball valve is opened and close reduces the power of opening and close. Through the design of the arris piece on the ellipse spheroid, further reduce the power of opening and close simultaneously. Ellipse spheroid is spherical with the contact surface of valve body, has stopped impurity by the situation of valve body and the jam of ellipse spheroid. The utility model discloses it is convenient that simple structure, preparation make things convenient for, use.
Description
Technical field
This utility model relates to valve technology field, particularly relates to the ball valve that a kind of hoisting capacity is little, be prone to keying.
Background technology
Valve is the control parts in fluid delivery system, has cut-off, regulation, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.Ball valve, butterfly valve, cone valve etc. can be divided into according to the difference of spool shape in valve.Ball valve is that opening and closing element (spheroid) is driven by valve rod, and the valve rotated around ball valve axis.Also can be used for regulation and the control of fluid, the most firmly seal, between V-type ball valve its V-type core and metal seat valve of pile-up welding hard alloy, there is the strongest shearing force, be particularly well-suited to the medium of fibre-bearing, small solid material etc..And multi-pass ball valve not only can control the interflow of medium, shunting and the switching flowed on pipeline flexibly, also can close arbitrary passage simultaneously and make two other passage be connected.This class valve the most typically should be horizontally mounted.Ball valve is divided into according to type of drive: pneumatic ball valve, electrical ball valve, manual ball valve etc..The compact conformation of ball valve, seal reliable, simple in construction, easy to maintenance, sealing surface and sphere, often at closure state, are difficult to by medium erosion, easily operated and maintenance, it is applicable to the general work media such as water, solvent, acid and natural gas, is mainly used in blocking or connecting the medium in pipeline, also can be used for regulation and the control of fluid.
Presently used ball valve, although its fluid resistance is little, the ball valve of full-bore does not has flow resistance substantially.But when it opens and closes, lack and can produce certain resistance, if especially pipeline having impurity, being very easy to be blocked by impurity, causing valve to open.
Utility model content
The purpose of this utility model is to solve the deficiencies in the prior art, it is provided that a kind of hoisting capacity is little, be prone to the ball valve of keying.
The technical solution adopted in the utility model is: a kind of ball valve, including valve body and valve rod, it is provided with oval ball in described valve body, described oval ball is connected with valve body by valve rod, solid connection fixed seat above described valve rod, the affixed valve block of described stem lower portion, described valve block is connected with body cavity；It is provided with sealing ring between described oval ball and valve body；Being connected with some rib sheets on described oval ball, described rib sheet is parallel to each other.
As further improvement of the utility model, described sealing ring is O RunddichtringO, and suitable with body cavity.
This utility model uses and provides the benefit that: original circular valve plate is changed to oval-shaped ball by the ball valve of this structure, and the contact surface that its both sides contact with medium is elliptic design, thus reduces resistance when ball valve opens and closes, and reduces hoisting capacity.Simultaneously by the design of the rib sheet on oval ball, reduce hoisting capacity further.Oval ball and the contact surface of valve body are spherical, have stopped the situation that impurity is blocked by valve body and oval ball.This utility model simple in construction, easy to make, easy to use.
Accompanying drawing explanation
Fig. 1 is this utility model schematic diagram.
Shown in figure: 1 oval ball, 2 valve rods, 3 valve blocks, 4 valve bodies, 5 fix seat, 6 sealing rings, 11 rib sheets.
Detailed description of the invention
Below in conjunction with Fig. 1, this utility model is described further.
As it is shown in figure 1, a kind of ball valve, including valve body 4 and valve rod 2, being provided with oval ball 1 in described valve body, described oval ball 1 is connected with valve body 4 by valve rod 2, solid connection fixed seat 5 above described valve rod 2, the affixed valve block in described valve rod 2 bottom 3, described valve block 3 is connected with valve body 4 inner chamber；It is provided with sealing ring 6 between described oval ball 1 and valve body 4；Being connected with some rib sheets 11 on described oval ball 1, described rib sheet 11 is parallel to each other.
Its valve plate of traditional ball valve is circular configuration and the contact surface that contacts with medium is plane, and traditional spherical valve plate is changed to oval valve plate by this utility model, and oval possess the most streamlined relative to spherical, improves percent of pass.Oval ball is also oval with the contact surface of valve body simultaneously, thus more smooth, has stopped the problem that impurity is detained.The surface of oval ball is provided with rib sheet, and rib sheet one is bigger impurity to be diverted to oval ball both sides, utilizes the impulsive force between oval ball and valve body to be washed away by impurity；Two be the design of rib sheet advantageously in the rotation of oval ball, thus reduce hoisting capacity.
Original circular valve plate is changed to oval-shaped ball by the ball valve of this structure, and the contact surface that its both sides contact with medium is elliptic design, thus reduces resistance when ball valve opens and closes, and reduces hoisting capacity.Simultaneously by the design of the rib sheet on oval ball, reduce hoisting capacity further.Oval ball and the contact surface of valve body are spherical, have stopped the situation that impurity is blocked by valve body and oval ball.This utility model simple in construction, easy to make, easy to use.
Those skilled in the art should know; protection scheme of the present utility model is not limited only to the above embodiments; various permutation and combination and conversion can also be carried out on the basis of above-described embodiment; on the premise of this utility model spirit, the various conversion carrying out this utility model all fall within protection domain of the present utility model.
