Abstract
The utility model relates to a special tool for a ball valve and aims to solve the problems of safety and reliability when the ball valve is opened and closed. The utility model provides a simple and reliable ball valve switch tool. According to a specific scheme, the ball valve switch tool comprises an operating rod and a fixing shaft which are fixed with each other; a sleeve ring is movably sleeved on the fixing shaft; a ball valve casing pipe which is vertical to the fixing shaft is arranged at one end of the sleeve ring; a balancing weight block is fixedly arranged at the other end of the sleeve ring; the ball valve casing pipe and the balancing weight block are respectively located on two sides of the fixing shaft; and a limiting device is fixedly sleeved on the fixing shaft. The ball valve switch tool has the advantages that the personal risk generated when a switch is arranged in a higher position or is used for connecting the ball valve in a pipeline of dangerous articles is avoided and is simple in structure and reliable to work.
Description
Technical field
The utility model relates to a kind of ball valve specific purpose tool, particularly a kind of ball valve switching tools.
Background technology
Ball valve is simple in structure owing to it, the reliable sealing advantage is widely used in the industry-by-industry.Generally; Because the switch of ball valve only need use little moment that handle is rotated 90 degree; Therefore generally all closely operate or use inductive switch, for example utility model patent (notification number: CN101526145A, the day for announcing: 2009-09-09) of China national Department of Intellectual Property disclosed a kind of " ball valve near switch is housed " by name by manual work; Content is: comprise valve body, spool, valve rod, handle, be equipped with on the valve body near switch; One of its structure be near switch be contained in the ball valve place when opening or closing handle end over against the position; Its another structure is to be that the inductance type metal of threaded circular column type is near switch near open relation.Because the position that some ball valves is installed is than higher or be used for connecting the pipeline of dangerous material; Closely operate by manual work and to have certain danger; And use inductive switch not only to increase cost; And can bring reliability problems, therefore a kind of simple and reliable ball valve switching tools just becomes very necessary.
The utility model content
The purpose of the utility model is security and the reliability problems when solving switching ball, and a kind of simple and reliable ball valve switching tools is provided.
For realizing above-mentioned purpose, the utility model adopts following scheme: a kind of ball valve switching tools comprises control stick and fixed axis; Said control stick and fixed axis interfix; Said fixed axis is provided with the collar of pivot bush unit, and an end of the said collar is provided with the ball valve sleeve pipe perpendicular to fixed axis, and the other end setting of the said collar is fixed with balancing weight; And ball valve sleeve pipe and balancing weight lay respectively at the both sides of fixed axis, and also fixedly sleeved on the said fixed axis have a stopping means.Hold control stick during use, entangle the handle of ball valve and promote control stick, make cover rotate and block, continue to promote control stick the handle of ball valve is rotated, open or close ball valve up to the limited device of ball valve sleeve pipe around fixed axis with the ball valve sleeve pipe.
As preferably, the utility model also comprises the weight linear meter between the said collar and balancing weight, and said weight linear meter connects the collar and balancing weight.Weight linear meter can drive balancing weight and under the gravity effect, make ball valve sleeve pipe self-return, and use convenient next time.
As preferably, the axis of the center line of said balancing weight, the axis of weight linear meter, ball valve sleeve pipe point-blank, and this straight line is through the center of the collar.Can guarantee that like this when bringing into use ball valve sleeve pipe can stably entangle the handle of ball valve, is convenient to operation.
As preferably, said control stick and fixed axis are perpendicular.Direction can be consistent in use with the ball valve sleeve pipe for control stick like this, is convenient to the operation that the ball valve sleeve pipe entangles ball valve handle.
As preferably, the scope that said ball valve sleeve pipe rotates around fixed axis is 0 degree-90 degree.When the limited device of ball valve sleeve pipe blocks, be in the state vertical with control stick like this, can obtain maximum moment when promoting the lever switch device ball valve with same dynamics, it is more laborsaving to make that the utility model uses.
As preferably, the said collar is provided with screw rod at the link position with the ball valve sleeve pipe, and said ball valve sleeve pipe is connected with said screw rod through built-in screw thread.Can change the ball valve sleeve pipe of different inner diameters like this according to the size of ball valve handle, improve the scope of application of the utility model.
As preferably, said stopping means comprises two position-limit foots and the limited block that is connected this two position-limit foot, and two position-limit foots lay respectively at the both sides of the collar.Such stopping means is simple and reliable for structure.
The beneficial effect of the utility model is: avoided switch to be arranged at the risk that eminence or be used to produces the person when connecting the ducted ball valve of dangerous material, and also simple structure, reliable operation.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further:
Like Fig. 1, shown in Figure 3; A kind of ball valve switching tools comprises the control stick 1 and fixed axis 2 of mutual vertical fixing, and movable sleeve is connected to a collar 3 on the fixed axis 2; Be fixed with a weight linear meter 7 and a screw rod 9 on the outer surface of the collar 3; The other end of weight linear meter 7 is fixed with balancing weight 8, and ball valve sleeve pipe 4 is connected with screw rod 9 through built-in screw thread, can change the ball valve sleeve pipe 4 of different inner diameters according to the handle size of ball valve; Weight linear meter 7 and ball valve sleeve pipe 4 lay respectively at the both sides of the collar 3; And the axis of the axis of the center line of balancing weight 8, weight linear meter 7, ball valve sleeve pipe 4 point-blank, and the center of this straight line process collar 3, and weight linear meter 7 is vertical with fixed axis 2 respectively with ball valve sleeve pipe 4; Like Fig. 2, shown in Figure 3, fixed cover is connected to two position-limit foots 6 on the fixed axis 2 of the collar 3 both sides, and limited block 5 fixes with two position-limit foots 6 respectively, and limited block 5 is limited to 0 degree-90 degree with ball valve sleeve pipe 4 around the angular range of fixed axis 2 rotations.
When needing the ball valve of switch eminence; Hold control stick 1; Entangle the handle of ball valve and promote control stick 1 with ball valve sleeve pipe 4, make the collar 3 rotate and contact with limited block 5 that this moment, control stick 1 was in vertical position with the handle of ball valve up to ball valve sleeve pipe 4 around fixed axis 2; Continue to promote control stick 1 handle of ball valve is rotated, open or close ball valve until on demand; Control control stick 1 after accomplishing and make the handle of ball valve sleeve pipe 4 disengaging ball valves also vertical, the whereabouts is parallel with control stick 1 until ball valve sleeve pipe 4 automatically for balancing weight 8 under the gravity effect, the preparation next operation.
