Description

TECHNICAL FIELD

[0001] The utility model relates to ball valve technical field, concretely is a kind of support shaft type forged steel fixed ball valve. BACKGROUND

[0002] In the process of continuous development in the industrial field, the accuracy and reliability of fluid delivery and control systems are crucial. With the large-scale expansion of the oil, gas, chemical and other industries, the demand for pipeline valves is increasing and the requirements are becoming more and more stringent. The support shaft type forged steel fixed ball valve emerges as the times require, which is rooted in the traditional valve technology. Through the forging process, the internal organization of the steel is more compact, which can effectively resist medium scouring and external impact. Its application in ball valve manufacturing greatly improves the operation efficiency.

[0003] When the staff tries to adjust the small flow, the rotation angle of the ball is difficult to control. From the structure of the through hole, the through hole of the current part of the ball valve is relatively simple, usually only a single circular straight hole is used. When multiple media flow through the ball valve at the same time, uneven flow rate and excessive local pressure may occur, affecting the stable operation of the entire pipeline system and bringing uncertainty factors to the subsequent mixing reaction. UTILITY MODEL CONTENT

[0004] The utility model aims at providing a support shaft type forged steel fixed ball valve to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a support shaft type forged steel fixed ball valve, comprising: a pipeline body;

[0006] A transmission assembly is arranged on the top of the pipeline body. The transmission assembly comprises a second fixed cover fixedly connected to the pipeline body, a rotating layer rotatably connected to the second fixed cover, a transmission rod slidably connected to the rotating layer, a first rotating block slidably connected to one end of the transmission rod away from the rotating layer, a threaded rod fixedly connected to the first rotating block, a second rotating block rotatably connected to the threaded rod, a first fixed cover slidably connected to the rotating layer, and a small mechanical telescopic rod fixedly connected to one end of the transmission rod away from the rotating layer.

[0007] A connecting plate is fixedly connected to both ends of the pipeline body. A bottom bin is fixedly connected to the bottom of the pipeline body.

[0008] A valve ball is threadedly connected to the threaded rod.

[0009] Further, a universal joint is fixedly connected between the rotating layer and the transmission rod.

[0010] By fixing the universal joint between the rotating layer and the transmission rod, the transmission rod is prevented from being broken when the rotating layer drives the transmission rod to move.

[0011] Further, a through hole is formed in the bottom of the valve ball.

[0012] By forming the through hole in the bottom of the valve ball, when the through hole in the valve bottom is completely exposed inside the pipeline body, the internal fluid can pass through the through hole.

[0013] Further, the bottom bin is made of rubber material, and the valve ball is in sliding connection with the bottom bin.

[0014] By setting the bottom bin to be made of rubber material, the sealing performance of the valve ball in the bottom bin is improved.

[0015] Further, a limiting frame is fixedly connected between the first fixed cover and the second fixed cover, and the rotating layer is in sliding connection in the limiting frame between the first fixed cover and the second fixed cover.

[0016] By setting the limiting frame, the rotating layer is facilitated to slide.

[0017] Further, a pushing piece is fixedly connected to the rotating layer.

[0018] By fixing the pushing piece to the rotating layer, the rotating layer is facilitated to be pushed by the staff during use.

[0019] Further, the pushing piece is in sliding connection in the limiting frame between the first fixed cover and the second fixed cover.

[0020] By avoiding that the pushing piece is excessively pushed to cause the rotating layer to slide too much during use.

[0021] Compared with the prior art, the advantages and positive effects of the utility model lie in that,

[0022] In the utility model, the staff operates the pushing piece, the pushing piece drives the rotating layer fixedly connected thereto to rotate between the first fixed cover and the second fixed cover, the small mechanical telescopic rod on the transmission rod drives the first rotating block to lift or drop, the first rotating block is in fixed connection with the threaded rod, the threaded rod is in rotary connection with the second rotating block, and finally the lifting control of the valve ball in threaded connection with the threaded rod is realized. When the valve ball is at different positions, not only the water flow can be completely cut off, but also the water flow proportion passing through the through hole and the periphery of the valve ball can be regulated, and the problem that the flow rate is uneven and the local pressure is too large when multiple media flow through the ball valve at the same time is effectively solved.

[0034] The connecting plate 3 is fixedly connected to the pipe body 1 at both ends, and the bottom bin 31 is fixedly connected to the bottom of the pipe body 1;

[0035] The valve ball 4 is threadedly connected with the threaded rod 28.

[0036] In the utility model, the staff operates the push piece 25, the push piece 25 drives the rotating layer 22 fixedly connected therewith to rotate between the first fixed cover 21 and the second fixed cover 29, the small mechanical telescopic rod on the transmission rod 23 drives the first rotating block 26 to lift or drop, the first rotating block 26 is fixedly connected with the threaded rod 28, the threaded rod 28 is further rotationally connected with the second rotating block 27, and finally the lifting control of the valve ball 4 threadedly connected with the threaded rod 28 is realized; when the valve ball 4 is at different positions, not only the complete cutting of water flow can be realized, but also the water flow proportion passing through the through hole and the periphery of the valve ball 4 can be regulated and controlled, and the problems of uneven flow velocity and excessive local pressure when multiple media flow through the ball valve at the same time are effectively solved.

[0037] Further, as shown in Figures 1 to 5 The rotating layer 22 is fixedly connected with the universal joint 24 between the transmission rod 23, the universal joint 24 is fixedly connected between the rotating layer 22 and the transmission rod 23, and when the rotating layer 22 drives the transmission rod 23 to move, the transmission rod 23 is prevented from being broken.

[0038] The bottom of the valve ball 4 is provided with a through hole, the through hole is provided in the bottom of the valve ball 4, when the through hole in the bottom of the valve is completely exposed in the pipe body 1, the internal fluid can pass through the through hole.

[0039] The bottom bin 31 is made of rubber material, the valve ball 4 is slidably connected with the bottom bin 31, the bottom bin 31 is made of rubber material, and the sealing performance of the valve ball 4 in the bottom bin 31 is improved.

[0040] The first fixed cover 21 and the second fixed cover 29 are fixedly connected with a limiting frame, the rotating layer 22 is slidably connected in the limiting frame between the first fixed cover 21 and the second fixed cover 29, and the limiting frame is arranged, so that the rotating layer 22 is conveniently slid.

[0041] In the above scheme, the rotating layer 22 is prone to falling off, as shown in Figure 3 And Figure 4 The push piece 25 is fixedly connected to the rotating layer 22, the push piece 25 is fixedly connected to the rotating layer 22, and the staff conveniently drives the rotating layer 22 during use.

[0042] The push piece 25 is slidably connected in the limiting frame between the first fixed cover 21 and the second fixed cover 29, and when used, the push piece 25 is prevented from being excessively driven to cause the rotating layer 22 to slide too much.

[0043] Working principle: as shown inFigures 1-4 As shown,

[0044] In use, the connecting plate 3 is connected with the pipeline by bolts;

[0045] The space in the pipeline body 1 needs to be tightly sealed, and when the water flow is cut off, the valve ball 4 is completely sunk into the bottom bin 31;

[0046] When the water flow needs to pass, the staff fluctuates the push piece 25, so that the push piece 25 drives the rotating layer 22 to rotate between the first fixed cover 21 and the second fixed cover 29;

[0047] At this time, under the pulling action of the transmission rod 23, the mechanical telescopic rod on the transmission rod 23 is stretched to the limit, and then drives the first rotating block 26 to lift a small distance, so that the first rotating block 26 lifts the valve ball 4 by a distance through the threaded rod 28 and the second rotating block 27. Since the valve ball 4 is provided in a spherical structure, at this time, a gap appears in the pipeline body 1, and the water flow can pass through, and under the extrusion action of the bottom bin 31, the water flow still cannot pass through the through hole on the valve ball 4;

[0048] When it is necessary to further reduce the flow rate, the valve ball 4 is continuously lifted, the through hole on the valve ball 4 is exposed, part of the water flow will be further hindered by the valve ball 4, and more water flow will pass around the valve ball 4, realizing the reduction of the flow rate, and the through hole on the valve ball 4 can avoid completely sealing the pipeline body 1.
