Description

TECHNICAL FIELD

[0001] The utility model relates to a valve, in particular to a high platform locking manual ball valve. BACKGROUND

[0002] The opening and closing part of the ball valve is driven by the valve rod and rotates around the ball valve axis. It can also be used for fluid regulation and control. The multi-way ball valve can not only flexibly control the flow, distribution and flow direction switching of the medium on the pipeline, but also can close any channel to connect the other two channels. Ball valves are divided into pneumatic ball valves, electric ball valves and manual ball valves according to the driving mode.

[0003] The existing market locking manual ball valve structure is to slide the locking block on the handle, and set the locking groove on the valve body corresponding to the sliding path of the locking block. The locking block enters the locking groove under the action of gravity to form a steering lock for the handle. Since there is no limiting structure for the locking block, when continuous opening and closing control of the ball valve is required, one hand needs to control the locking block to prevent it from falling and interfering with the opening and closing operation, and the other hand needs to control the handle to rotate. This setting method of the locking block will interfere with the continuous control operation of the ball valve to some extent in some special use scenarios, thereby increasing the complexity of the operation and affecting the timeliness of the ball valve control. SUMMARY

[0004] The utility model aims at providing a kind of high platform locking manual ball valve, the operation of the high platform locking manual ball valve is more convenient, to ensure the timeliness of ball valve control.

[0005] The above technical purpose of the utility model is realized by the following technical scheme: a kind of high platform locking manual ball valve, including valve body, the valve cover being installed in the side of valve body, the valve rod being installed in valve body, the ball being set in valve body and being connected with valve rod, the handle being connected with valve rod, the locking block being slidably arranged in handle and having the movement tendency towards the side of valve rod and the locking groove being set in valve body and being directly corresponding to the movement path of locking block, the mobile assembly that the handle is slidably arranged with the movement direction of locking block and drives locking block synchronous movement is provided, locking assembly is equipped on the mobile assembly, and the locking assembly has the stepless locking state of restricting the movement of mobile assembly and non-locking state.

[0006] By adopting the technical scheme, the locking assembly is switched to the non-locking state, the moving assembly can cooperate with the gravitational potential to drive the locking block to reciprocate towards the locking groove, so as to control whether the locking block enters the locking groove. When the locking block enters the locking groove, the locking of the valve is formed through the limiting cooperation between the two. By switching the locking assembly to the stepless locking state, the locking block in motion can be locked in real time, so that the locking block does not interfere with the operation when the ball valve is continuously operated and controlled, the operation of the ball valve is more convenient, and the timeliness of the ball valve control is ensured.

[0007] Further, the moving assembly comprises a sliding groove arranged on the handle and a sliding block slidingly arranged in the sliding groove, and the sliding groove extends along the length direction of the handle.

[0008] By adopting the technical scheme, the sliding block slides in the sliding groove, so as to drive the locking block to reciprocate towards the locking groove.

[0009] Further, the sliding block and the locking block are connected by a linkage rope, the handle is provided with a guide ring through which the linkage rope passes, and the linkage rope passes through the guide ring to guide the locking block to reciprocate towards the locking groove.

[0010] By adopting the technical scheme, the guide ring is arranged to change the direction of the force, so that the linkage rope can better cooperate with the gravity to drive the locking block to enter and exit the locking groove, and the reciprocating motion of the locking block is realized.

[0011] Further, the locking assembly comprises a control block slidingly arranged on the sliding block and moving with the sliding block, a stop block moving with the sliding block and abutting against one side of the sliding groove wall, and a linkage structure cooperating with the control block to control the stop block to abut against the one side of the sliding groove wall away from the sliding groove wall, and the stop block is made of elastic material.

[0012] By adopting the technical scheme, the stop block made of elastic material abuts against the one side of the sliding groove wall, and the frictional resistance formed between the two is used to limit the movement of the sliding block, so as to achieve the stepless locking purpose of the moving assembly. When the control block drives the stop block to abut against the one side of the sliding groove wall away from the sliding groove wall through the linkage structure, the locking is released. This kind of arrangement has simple structure and lower processing cost.

[0013] Further, the one side of the stop block abutting against the sliding groove wall is an abutting surface, the linkage structure is a linkage part moving with the control block and fixedly connected with the stop block, and the linkage part moves with the control block to drive the abutting surface away from the sliding groove wall.

[0014] By adopting the technical scheme, the linkage part moves with the control block to drive the stop block to elastically deform and make the abutting surface away from the sliding groove wall, so as to achieve the unlocking purpose.

[0015] Further settings are that the stop block is provided with a deformation hole, and the linkage part extends into the deformation hole and is fixed at a position where the deformation hole wall faces away from each other.

[0016] By adopting the technical scheme, the linkage part can better apply the force in the direction away from the slide groove wall to the stop block, and the abutting surface is more conveniently driven away from the slide groove wall, and the operation is more convenient.

[0017] Further settings are that the installation cavity is formed between the valve body and the valve rod, a compression ring is slidably arranged in the installation cavity along the valve rod axis, a sealing ring is arranged above the compression ring in the installation cavity, and a driving cavity communicated with the inner cavity of the valve body is formed below the compression ring.

[0018] By adopting the technical scheme, when the pressure in the inner cavity of the valve body increases, the compression ring is driven to move towards the sealing ring side in the driving cavity to extrude the sealing ring, so as to improve the sealing force of the sealing ring, the sealing force of the sealing structure can be increased with the increase of the pressure in the valve, and better sealing effect is achieved.

[0019] Further settings are that the top of the installation cavity forms an abutting inclined surface gradually inclined towards the valve rod, and the sealing ring extends into the abutting inclined surface.

[0020] By adopting the technical scheme, the abutting inclined surface further extrudes the entering sealing ring, and better sealing effect is achieved.

[0021] In summary, the utility model has the following beneficial effects: the operation of the utility model is more convenient, and the timeliness of the ball valve control is ensured. BRIEF DESCRIPTION OF DRAWINGS
