Description

BALL VALVE WITH A PROTECTION AGAINST THE CHANGE OF THE

FLOW ADJUSTMENT

The subject of the invention is a ball valve with integrated protective device for liquid medium flow adjustment, a stepwise flow adjustment mechanism and an insert which enables the linear and logarithmic flow of this medium.

With this invention, the technical problem is solved in that the ball valve is constructed so as to be able to stepwise regulate the flow of the medium through the ball valve with a protection device which allows the flow rate of the liquid medium to vary. this mechanism has a button with two legs with toothing, which coincides with the set flow of the liquid medium with the teeth on the flow scale carrier. The ball valve also has an insert that allows for linear and logarithmic flow of the liquid medium depending on the button turns and the degree position on the ball valve housing. The invention also solves the protection of the protection of the change in the flow settings against the failure of the taps on the basis of blocking with a cord with seal or with the completion of the padlock.

The existing known solutions of ball valves meet only partially the advantages of this invention, because they have no mechanical protection device of the change in flow setting and no backup of this protection against failure from the taps with the help of a cord and a seal or a padlock. The existing technical solutions also do not allow a linear or logarithmic flow of the liquid medium through the tap, as well as any accurate repeatable flow settings of the liquid medium as desired by the user. In the wide field of use of the ball valves more and more demands of users for taps, which can be gradually regulated with a protection device that allow a linear and logarithmic flow of the liquid medium at the tap outlet and are equipped with a precise repeatable Stufendurchflusseinstellung of the liquid medium. The secured positions of the ball valve stage adjustment allow the safety of the hydraulic processes of the ball valve user to be prevented by the unauthorized person changing the flow adjustment of the liquid medium through the ball valve. Such a construction solution of the ball valves represents a great advantage compared to the existing construction solutions of the ball valves, because it combines four different important functions, such as: the protection of the staged flow adjustment of the liquid medium by the tap, the protection against the change of attitude by unauthorized persons, the possibility of linear and logarithmic flow at the tap outlet, and accurate repeatable step flow adjustment of the liquid medium through the tap.

In the ball valve finder with built-in stopcock control of the liquid medium through the tap, which enables the linear and logarithmic flow of the liquid medium at the tap outlet and a precise repeatable staged flow adjustment of the liquid medium through the tap, the problem is solved in that ball valve Built-in protection device which can be sealed prior to intervention by unauthorized persons with a seal or a padlock; that this tap has an insert which allows a linear and logarithmic flow of the liquid medium; that the tap has a button with two legs with teeth for a good grip on the flow scale carrier and that such a design solution of the adjustment mechanism ensures an accurate stepwise flow adjustment of this medium. Thus, this ball valve provides a mechanical assurance of the setting positions of the knob, securing the current flow rate of the liquid medium through the tap, a linear and logarithmic flow of the liquid medium in all possible repeatable settings of the knob positions, and a precise stepwise flow adjustment of the liquid medium through the ball valve.

We achieve the change of the button position of the ball valve and thus the change of the flow of the liquid medium through the tap so that we push the button first axially in the direction "x" down and then push him in the desired direction so that the teeth When the flow of the liquid medium through the tap is so adjusted, we place between the housing of the scale carrier attached to the tap body and the protector button of the flow meter on the button legs with the teeth of the flow scale Change in the flow setting, which makes it impossible to move the knobs axially in the direction "X", thus ensuring the flow adjustment of the liquid medium by the tap The protection of changing the flow setting with the possibility of tap failure prevention due to change of setting by unauthorized persons has been designed in accordance with this invention in two designs, namely the flow-rate change protection device which has two holes for the use of a cord with a seal or a padlock on its legs. Both of the specified safety options make it impossible for an unauthorized person to change the flow of the liquid medium through the valve and forcibly remove these protective devices from the taps. The change of the flow setting of the liquid medium by the tap with the help of the button or a new knob setting and thus a new flow setting, the removal of the sealing cord or the padlock, the removal of the protection device of the adjustment valve in the opposite direction »W«, requires a new flow setting with the help of the button and a new protection device with the help of a valve.

The ball valve, which enables the securing of the flow adjustment and thus the securing of the flow adjustment of the liquid medium by the tap, the linear in logarithmic flow of the liquid medium through the tap and the exact repeatable stage setting, consists of the housing 1, in whose hole 66 the Shaft 3 is inserted, which is sealed with the housing 1 with the rubber seal 17, and is guided with plastic guides 15, 16 and 18. In the housing 1, the ball 20 with insert inserted 21, which allows the linear and logarithmic flow of the liquid medium at the ball valve outlet. Between the ball 20 and the insert 21 are in the grooves 70 on the insert 21, two rubber rings 23, which avoid unwanted vibrations during flow of the liquid medium through the ball valve. The shaft 3 has because of the transmission of torque with the ball 20 has a flat projection 32 which is located in the semicircular groove 33 on the ball 20. The shaft 3 has two blind holes 57 with two compression springs 58, each of which presses on the ball 59 which is pressed to avoid the failure of the shaft 3 from the shaft 3 because of the ease of assembly. The housing 1 is sealed with the flanges 2 or flanges 46 on both sides with rubber seals 4, but the ball 20 is guided in the valve housing 1 with plastic side guides 22, which have four halbkreisnuten 69 at the outer edge. The ball valve flanges are the same as the flanges 2, without the possibility of the sensor connection, or as valve flanges 46 with connections 45 for the sensor connection. The connection of the sensor to the flanges 46 is possible with Help of threaded holes 47 at the sensor terminals 45. The flanges 2 or 46 are connected to each other and to the housing 1 by means of spring washers 27, nuts 28 and four screws 26 projecting from the holes 48 and the eyelets 49, to the Flanges 2 or flanges 46 are located, with one of these screws protrudes from the hole 50, which is located on the rib 51 on the housing 1. On the shaft 3 is the thread 34 to which the nut 13 is attached to the plastic washer 14. The nut 13 is secured against rotation with a protective device 12 so that it wraps around with its legs 60, the hexagonal part of the nut 65. On the valve housing 1 is the flow scale carrier 5, which is connected to the housing with the screws 29, spring washers 30 and nuts 31, through the holes 35 on the flow scale support 5 and the holes 36, which are located on the flanges 64 of the housing 1, is attached. The mother protection device 12 is attached to the square neck 37 of the valve shaft 3 by means of its square hole 38. At the square neck 37 of the valve shaft 3, the knob 7 is attached by means of its square hole 39. At the flow scale carrier 5 is the flow scale 6, which can be expressed in angular, flow or other units. Between the flow scale support 5 with the flow scale 6 and the knob 7 is the prestressed compression spring 9, which presses the button with its toothing 40, which is located on the leg 41 in the handle of the toothing 42 on the flow scale carrier 5. In the round hole 43 on the knob 7 is the socket 8, which creates the distance between the knob 7 and the shaft 3. In the round hole 44 of the bush 8 is the screw 11 with washer 10, which fixes the knob 7 with the shaft 3. On the valve knob 7 is the foster 62 with the help of which we can set the button position and thus the amount of flow of the liquid medium through the ball valve exactly. The ball valve is available as a variant with flanges 2 without installation possibility of the sensor connection 45 or with the flanges 46 with sensor connections 45 for the sensor installation. The flanges 2 or flanges 46 are fastened together and the housing 1 with spring washers 27, nuts 28 and four screws which project through the holes 48 at the flanged eyelets 49. One of the screws protrudes from the hole 50, which is located on the rib 51 of the housing 1. Between the flow scale carrier 5, on which the flow scale 6, whose position on the scale 5 of the requirement for linear flow of the liquid medium from the ball valve or logarithmic flow of the liquid medium from the Ball valve depends, and the valve knob 7, the protection device may be the change in the flow adjustment 24, at which the holes 52 through which you can pull the cord 53 with seal 54 or the protection device against the change of the flow adjustment 25 with the holes 55th , which serves to insert the padlock 56. Alternatively, the ball valve housing is designed in the design with the housing 75 where 75 threaded ports 77 are screwed to both sides of the housing, which have no sensor terminals 45 or threaded into the terminals 78 are screwed with sensor terminals 45. Alternatively, the ball valve housing is also in the construction design with the housing 76, wherein on one side of this housing 76, the threaded connection 77 is screwed without sensor connection 45 or screwed into the threaded connection 78, which has the possibility of the sensor connection 45. On the other side of the housing 6 but the thread for the screw connection of the inlet tube is integrated with the housing 76 itself.

We achieve the linear exit of the liquid medium from the ball valve so that, with the valve closed, we fix the scale 6, which is located on the flow scale support 5, so that with the knob turn to the right, the right angle area of the flow regulation from zero to ninety degrees is covered. The logarithmic discharge of the liquid medium from the ball valve is achieved so that, with the valve blocked, the scale 6 located on the flow scale carrier 5 is fastened so that with the button rotation to the left, the left angle region of the flow regulation is from zero to ninety degrees is covered.

We construct the ball valve, which, with the aid of the protection device against the change of the flow setting 24 or the protection against the change of the flow setting 24, which allows the securing of the button level adjustment or the precise gradual flow adjustment of the liquid medium through the ball valve, together so that first to the shaft 3, the wave guide 18 is installed of plastic, and then the rubber seal 17. Then we introduce into the hole 66 of the housing 1, the plastic shaft guides 15 and 16 and the plastic washer 14 a. The thus assembled shaft 3 is inserted into the housing 1. It follows the insertion of the ball 20 in the housing 1, wherein in the ball 20 previously the insert 21 with two rubber rings 23 is inserted so that the flat end piece 32 of the valve shaft 3 in the semicircular groove 33, which is located on the ball 20, is applied. It follows the insertion and the screwing of the nut 13 to the thread 34 of the shaft 3, and placing the protection device 12 by means of its square hole 38 on the square neck 37 of the shaft 3 so that the legs 60 of the protection device 12, the hexagonal part 65 of Nut 13 include, and thus prevent the mother is loose.
