Abstract
The utility model discloses a novel ball valve, including valve body, valve gap, spheroid, valve rod and handle, install the disk seat in the valve body, the spheroid is located and contacts between the disk seat and with the disk seat, the valve rod bottom is passed the valve gap and is connected with the spheroid, the valve rod top is connected with the handle, for the mirror surface contact between spheroid and the disk seat, be equipped with spheroid support piece on the valve body of spheroid below, space department between spheroid bottom and the valve body is equipped with one and unloads the hydraulic fluid port, unload and install the cock in the hydraulic fluid port. The utility model discloses not only sealing performance is high, long service life, does not have the sealing washer moreover and damages the phenomenon that causes the ball valve oil leak.
Description
Technical field
The utility model relates to a kind of production tree equipment, is specifically related to a kind of ball valve of production wellhead.
Background technique
Ball valve common on market normally by a sphere installation with through hole on the valve seat of valve inner, realized closedown and the unlatching of valve by rotating sphere, between spheroid and valve seat, be provided with seal ring toward contact, seal ring generally adopts soft material.Because the frictional ratio between spheroid and valve seat is comparatively large, after Long-Time Service, seal ring there will be wearing and tearing, and sealing declines, and as changed not in time, liquid can enter from the gap location between spheroid and valve seat, and then occurs oil leakage phenomenon; In addition, liquid enters the pressure that not only can increase valve body after between ball valve and body base, reduces the working life of valve body, and can increase the keying difficulty of valve body.
Summary of the invention
For solving the problem, the utility model discloses a kind of ball valve, sealability be high, long service life, there is not seal ring and damage and cause the phenomenon of ball valve leakage of oil.
A kind of ball valve, comprise valve body, valve gap, spheroid, valve rod and handle, in described valve body, valve seat is installed, described spheroid is between valve seat and contact with valve seat, and described stem bottom is connected with spheroid through valve gap, and described valve stem top is connected with handle, described spheroid with between valve seat for minute surface contacts, valve body below described spheroid is provided with ball support part, and the gap bottom described spheroid and between valve body is provided with a unloading port, is provided with cock in described unloading port.
As further improvement of the utility model, described spheroid adopts Austenitic Stainless Steel to make.
As further improvement of the utility model, between described valve gap and valve rod, be filled with fluoroplastic.
Compared with prior art, the utility model tool has the following advantages and beneficial effect: owing to adopting minute surface to contact between spheroid with valve seat, so need not re-use seal ring, avoids and occurs the problems such as leakage of oil because seal ring damages not change in time; The design of ball support part can give a support force bottom spheroid, prevents the impact of medium to spheroid from spheroid is subjected to displacement; Oil between spheroid and valve seat can discharge by the design of unloading port, extends the working life of valve body.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, following embodiment should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.It should be noted that, the word "front", "rear" of use is described below, "left", "right", "up" and "down" refer to direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometrical center respectively.
As shown in the figure, a kind of ball valve, comprises valve body 1, valve gap 2, spheroid 3, valve rod 4 and handle 5, is provided with valve seat 6 in valve body 1, and spheroid 3 is between valve seat 6 and contact with the internal surface of valve seat 6.Be connected with spheroid 3 through valve gap 2 bottom valve rod 4, be filled with fluoroplastic between valve rod 4 and valve gap 2, improve the overall tightness of valve, valve rod 4 top is connected with handle 5, and handle is by the rotation of valve rod coordinated signals spheroid 3.
In order to ensure the sealing between spheroid and valve seat, between spheroid and valve seat, be also provided with soft seal ring in the past, but the frictional ratio between spheroid and valve seat is larger, after Long-Time Service, seal ring there will be wearing and tearing, and sealing declines, as changed not in time, liquid can enter from the gap location between spheroid and valve seat, and then occurs oil leakage phenomenon.In order to solve this problem, minute surface is adopted to contact in the present embodiment between spheroid with valve seat, utilize metal (surface roughness value ra≤0.05 μm of high finishingness, surface finishment is greater than 10) surface contact to be to realize the sealing between spheroid and valve seat, thus no longer need to use seal ring, in order to increase the wear resistance of spheroid 3, the spheroid in the present embodiment adopts Austenitic Stainless Steel to make, and improves corrosion-resistant, the wear resistance of spheroid.
In real production process, how good sealability no matter between valve seat and spheroid is, and oil all can more or less infiltrate from the gap location between valve seat 6 and spheroid 3, not only can increase the pressure of valve body, reduce the working life of valve body, and the keying difficulty of valve body can be increased.In order to solve this problem, the gap bottom spheroid 3 and between valve body is provided with a unloading port, is provided with cock 7 in unloading port, is discharged by the oil bottom spheroid 3 and between valve body by opening cock 7, by cock 7 precession unloading port after release terminates.
In addition, due under high pressure, medium causes spheroid that certain displacement occurs can to the certain impact of spheroid, in the course of time the degree of wear between spheroid and valve seat can be accelerated, therefore the valve body 1 below spheroid is provided with ball support part 8, spheroid support force can be given bottom spheroid, prevent spheroid from freeing skew.
Technological means disclosed in the utility model scheme is not limited only to the technological means disclosed in above-mentioned technological means, also comprises the technological scheme be made up of above technical characteristics combination in any.
