Abstract
The utility model relates to a clutch seat ball valve, which comprises a valve body, a valve cover, a valve rod and a spherical core, wherein the valve body at one side of the spherical core is provided with a slidable valve seat matrix; the valve seat matrix is provided with a valve seat matched with the sealing face of the spherical core; and both sides of the valve seat matrix are respectively provided with an opening pneumatic (hydraulic) tube and a closing pneumatic (hydraulic) tube which control the valve seat matrix to slide from side to side. The clutch seat ball valve overcomes the disadvantages of the prior art that an ordinary ball valve has large operating moment, easy friction abrasion of a sealing face, short service life and nonadjustable pretightening force; moreover, the prior ball valve can not be used for flow rate adjustment and has a narrower application range. With the design, a seal pair is capable of separating and combining during opening and closing so as to realize no contact, no friction and zero abrasion along with small operating moment and strong sealing property; meanwhile, the seal pair can adjust the flow rate of a pipeline medium.
Description
Affiliated technical field
The utility model relates to a kind of on-off seat globe valve.
Background technique
The ball valve genus blocks the class valve, be mainly used in the MEDIA FLOW of connecting or blocking in the pipeline, the sealing principle of ball valve, be to contact with spheroid according to two ends, preceding left and right sides valve seat to obtain sealability, the size of contact strength (pretightening force that is called sealing again), sealability is played crucial effects, pretightening force is big more, sealability is reliable more, and along with the frictional force between valve seat and spheroid increases, the frictionally damage of sealing surface is just big, and the moment of rotation of valve is directly proportional with frictional force, therefore, the opening-closing process of ball valve interior spheroid rotation is the pretightening force that operational torque overcomes sealing, the frictional force of material and the process of deadweight also are the processes of sealing pair fretting wear.Ball valve generally has only the working position of " complete opening " and " closing fully " in working condition, the working position is 90 degree and arranges, any orientation pause holdup time of the mid span of 0-90 degree is long, all may cause damage to sealing pair, so ball valve generally can not be used for Flow-rate adjustment, Applicable scope is narrower.
Summary of the invention
The operational torque of ordinary ball valve is big in order to overcome in the prior art, the easy fretting wear of sealing surface, working life is short, pretightening force is non-adjustable, and generally can not be used for Flow-rate adjustment, the problem that Applicable scope is narrower, the utility model provides a kind of on-off seat globe valve, this on-off seat globe valve sealing pair in the switching process can clutch realize that contactless, nothing rubs, zero wearing and tearing, and operational torque is little, and sealability is strong, and realizes the flow regulating function to the pipeline medium simultaneously.
The technological scheme that its technical problem that solves the utility model adopts is: comprise valve body, valve gap, valve rod and ball core, in the valve body of ball core one side, be provided with slidably valve seat matrix, the valve seat matrix is provided with the valve seat that matches with the sealing surface of ball core, the both sides of valve seat matrix be provided with respectively the left and right slip of control valve seat matrix unlatching gas (liquid) pressure pipe and pass (liquid) pressure pipe of holding one's breath.
The valve seat matrix is provided with the valve seat cylinder sleeve, form between the bulge loop of valve seat cylinder sleeve and valve seat matrix periphery and open the unlatching active chamber that gas (liquid) pressure pipe is connected and seal, the bulge loop and the pass of the valve seat matrix periphery active chamber of closing that formation seals between (liquid) pressure pipe of holding one's breath.
Open gas (liquid) pressure pipe and be arranged on the valve body, close (liquid) pressure pipe of holding one's breath and be arranged on the valve gap.
Be provided with elastic component between valve seat matrix and the valve gap.
The utility model has the following advantages by above-mentioned specific design:
1, sealing pair is real in opening-closing process realizes that contactless, nothing rubs, zero wearing and tearing, the working life of greatly having improved ball valve.
2, spheroid can be stagnated the arbitrary position in the aperture of 0-90 degree, makes the Flow-rate adjustment function of ball valve realization to the pipeline medium, has the function of adjusting, throttle valve.
3, the seal pressure of valve can compensate, can adjust, and sealability get a qualitative improvement.
When 4, valve opening and closing was operated, operational torque was not sealed the influence of active forces such as pretightening force, pipeline pressure, and operational torque is minimum.
Description of drawings
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in the figure, the utility model comprises valve body 1, valve gap 2, valve rod 3 and ball core 4, in the valve body 1 of ball core 4 one sides, be provided with slidably valve seat matrix 5, valve seat matrix 5 is provided with the valve seat 6 that matches with the sealing surface of ball core 4, the both sides of valve seat matrix 5 be provided with respectively the 5 left and right slips of control valve seat matrix unlatching gas (liquid) pressure pipe 13 and pass (liquid) pressure pipe 7 of holding one's breath.Open gas (liquid) pressure pipe 13 and can be arranged on the valve body 1, close (liquid) pressure pipe 7 of holding one's breath and to be arranged on the valve gap 2.Valve seat matrix 5 is provided with valve seat cylinder sleeve 8, form between the bulge loop 12 of valve seat cylinder sleeve 8 and valve seat matrix 5 peripheries and open the unlatching active chamber 9 that gas (liquid) pressure pipe 13 is connected and seal, the bulge loop 12 and the pass of valve seat matrix 5 peripheries holds one's breath that formation seals between (liquid) pressure pipe 7 closes active chamber 10.Be provided with elastic component 11 between valve seat matrix 5 and the valve gap 2, elastic component 11 adopts spring or shell fragment.When valve is made open operation, opening gas (liquid) pressure pipe 13 connects, gas (liquid) pressure enters the unlatching active chamber 9 of sealing, promoting valve seat matrix 5 and valve seat 6 slides along the pipeline axis, valve seat 6 is broken away from and the contacting of ball core 4, under the minimum situation of operational torque, ball core 4 can be rotated counterclockwise unlatching.When valve is made closing operation, ball core 4 can turn clockwise, hold one's breath (liquid) pressure pipe 7 of pass is connected, what gas (liquid) pressure entered sealing closes active chamber 10, promote valve seat matrix 5 and valve seat 6 along pipeline axis reverse slide, valve seat 6 tightly is pressed against on the sealing surface of ball core 4 to the seal pressure setting value, and closing motion is finished.
