Description

The utility model relates to general engineering, in particular to structural elements of tanks, namely, to the design of locking elements of tanks, for example, container tanks.

A device for draining and filling, consisting of three sequentially installed locking elements with independent from each other manual drives: ball valve, the body of which has a threaded pipe for connection to the pipeline and a flange for connection with the housing of the internal valve, a side hole for the spindle of the manual drive; mounted on the tap nozzle of a ball threaded plug; and an internal valve, the casing of which has a flange for connection with the casing of a ball valve, in which there is an opening for the spindle of a manual actuator, a flange for connecting to the tank located in the middle of the casing, an annular groove made on the outer surface between the flanges, with an internal locking body the internal valve is made integral, consisting of the main - spring-loaded for opening, and pilot - spring-loaded for closing and coaxially connected to the stem interacting with the conversion mechanism information on the rotational movement of the drive into the translational movement of the rod (Russian Federation Certificate for Utility Model No. 136866 of 2013, according to IPC class F16K 27/07).

However, the design of this device, the discharge and filling does not allow to completely empty the container tank.

The closest analogue is a bottom drain shutoff device manufactured by Fort Vale Engineering Limited (company registered in England & Wales, Company Registration No: 00902920, the official website for the information and telecommunication network "Internet" http.//www.fortvale.com/index.asp ), designed as a sealing device for a container tank used for loading and unloading a transported liquid product, comprising a housing with two locking bodies sequentially located in it with independent manual drives, an internal locking body - with a shut-off valve, an external locking element - a disk lock, and an additional external locking element in the form of a plug screwed onto a housing pipe (Fort Vale Engineering Limited company catalog. Official website on the Internet telecommunication network http://www.fortvale.ru/ katalog / 3-45-univalve-bottom-discharge-assembly /).

However, the design of this shut-off bottom drain device also has a technical problem. The design of the device does not allow to completely empty the container-tank, which leads to the need to drain the residues of the transported product “manually”, that is, by using additional means, in particular, for the subsequent washing operation of the container-tank before loading a new batch of product.

The solution to the above technical problem is provided in the design of the bottom shutoff device, comprising a housing with two locking bodies sequentially arranged in it with independent manual actuators, an internal locking body - an internal valve, an external locking body - a disk shutter, and an additional external locking body in in the form of a plug wound on the housing pipe while the internal locking element is made of two valves located in the functional-structural unity ANTONOV - main valve and emptying valve maximum tank container that eliminates the need to perform additional operations on drain residues transported product.

Thus, the technical result provided by the utility model is the possibility of complete emptying of the container tank.

The design of the locking bottom drain device is presented in

FIG. 1 is a main view of a locking lower drain device;

FIG. 2 is a left side view of a locking lower drain device;

FIG. 3 is a partial view A of the locking bottom drain device,

Where:

1 - handle; 2 - pipe; 3 - a stub; 4 - a disk lock; 5 - case; 6 - spindle; 7 - cam; 8 - pusher; 9 - the main valve; 10 - spool; 11 - valve for maximum emptying of the container tank; 12 - spool; 13 - spring; 14 - spring; 15 - fitting; 16 - tube; 17 - internal locking body; 18 - handle, 19 - tank container.

The overall design of the bottom shut-off device consists of a housing 5, two shut-off bodies located therein - a disk shutter 4, an internal shut-off body 17, consisting of a main valve 9, a valve for maximum emptying of the tank-tank 11. A disk shutter 4 and an internal shut-off body 17 equipped with independent from each other manual drives, handle 1 and handle 18, respectively. Also in the design there is an additional locking element in the form of a plug 3, screwed onto the pipe 2 of the housing 5.

The locking device of the lower drain works as follows:

After removing the additional locking element in the form of a plug 3 from the pipe 2 of the housing 5, a drain pipe is connected to the pipe 2 of the housing 5. Pressure is supplied to the container tank 19 through the air line pipe. External locking body - disk shutter 4 is translated into the open position by turning the handle 1 counterclockwise. After which the opening of the internal locking body 17 as follows.

When turning the handle 18 counterclockwise and turning it into an intermediate position, the spindle 6 rotates and through the cam 7 gives movement to the follower 8 which, resting against the spool 12 lifts it, while compressing the spring 13, when the stroke of the spool 12 is selected, depressurization occurs along the maximum drain valve container tank 11 and the product begins to flow through the tube 16, fixed at one end on the fitting 15, the second end of the tube 16 is fixed at the lowest point of the container tank 19. The maximum drain valve The tank container 11 is fully open. With a further rotation of the handle 18 counterclockwise and its translation into the final position, the spool 12, resting on the collar of the spool 10, raises it, compresses the spring 14, depressurizes the main valve 9, and the product flows through the main valve 9 - the main valve 9 fully open.

Complete emptying of the container tank 19 occurs after the cessation of product through the main valve 9 as follows.

When turning the handle 18 clockwise and translating it into an intermediate position, the spindle 6 rotates and through the cam 7 transmits the movement to the follower 8, which returns to the position corresponding to the intermediate position of the handle 18, while due to the force of the spring 14, the spool 10 returns to its original position, the main valve 9 is sealed - the main valve 9 is completely closed. Due to the supply of pressure through the pipeline of the air line to the container-tank 19, by squeezing, the product residues are drained through the tube 16, mounted on the fitting 15.

After the container tank 19 is completely emptied, when the handle 18 is further turned clockwise and returned to its original position, the spindle 6 is rotated and through the cam 7 transmits movement to the plunger 8, which returns to its original position, due to the force of the spring 13, the spool 12 returns to its original position, the valve for the maximum discharge of the container tank 11 is sealed - the valve for the maximum discharge of the container tank 11 is completely closed.

The butterfly valve 4 is moved to the closed position by turning the handle 1 clockwise. The plug 3 is screwed onto the pipe 2 of the housing 5. The product discharge operation is completed and the tank container 19 is ready for the washing operation before loading a new batch of product.

The proposed design of the bottom shutoff device, comprising a housing with two locking bodies sequentially arranged in it with independent manual actuators, an internal locking body - an internal valve, an external locking body - a disk shutter, and an additional external locking body in the form of a plug screwed onto the pipe In this case, the internal shut-off element is made of two valves located in the functional-structural unity - the main valve and the maximum emptying the tank container, allows to completely empty the container of the tank, eliminating the need to perform additional operations on drain transported product residues, in particular for operation of the washing tank container before loading a new batch.
