Description
Technical Field
The utility model relates to a pipeline liquid medium transportation equipment field specifically indicates a water attack resistant constant flow valve.
Background
The water hammer phenomenon is a phenomenon that the instantaneous pressure is obviously, repeatedly and rapidly changed due to the rapid change of the liquid flow speed in a pressure pipeline, and is called water hammer. When the valve of the pressure pipeline is suddenly closed or opened, and when the water pump is suddenly stopped or started, the instantaneous flow rate is suddenly changed, so that the momentum of the liquid is rapidly changed, and the pressure is remarkably changed. The water hammer phenomenon can also occur when the check valve fails on the pipeline. When the water hammer occurs, the pressure rise value is possibly many times of the normal pressure, so that the pipe wall material bears great pressure; repeated changes in pressure can cause vibration of the pipes and equipment, and in severe cases, can cause damage to the pipes, pipe fittings and equipment.
In current chemical industry, oil upstream and downstream industry, long distance pipeline is when carrying liquid medium, in order to prevent that the medium from arousing under the condition of turbulent flow or velocity of flow abrupt change that the water hammer phenomenon causes the destruction of pipeline annex, like pipeline valve, support, pump package etc. or reduce the life who shortens the pipeline, in order to increase the factor of safety that the pipeline carried, current solution is mostly when the pipeline design, just intentionally choose for use the pipe fitting or the pipeline annex of high pressure-bearing material to this security that is used for strengthening the pipeline.

Example 1:
referring to fig. 1-4, the water-hammer-resistant constant flow valve comprises a valve body 4, wherein a plurality of laminar flow pipes 5 are installed in the valve body 4, and a plurality of mutually independent buffer oil storage grids are arranged on the outer side of the valve body 4 in a surrounding manner along the circumferential direction of the valve body 4; an elastic saccular lining 3 is arranged in the buffer oil storage grid, the inner cavity of the elastic saccular lining 3 is communicated with a pipeline of the valve body 4 through an oil discharge hole 7, and an air hole 10 communicated with the cavity of the buffer oil storage grid is arranged on the outer wall of the buffer oil storage grid.
In the embodiment, the constant flow valve is butted with the conveying pipeline, when the liquid medium conveyed in the valve body 4 passes through the laminar flow pipe 5, the liquid medium is forced to be laminar flow by the laminar flow pipe 5, and therefore damage of the medium to the pipeline due to turbulence is reduced. Meanwhile, the liquid medium passes through the oil discharge hole 7 at a certain speed, the pressure in the cavity of the elastic saccular lining 3 is negative compared with the pressure in the valve body 4 under the double actions of interception and atmospheric pressure, and the volume of the elastic saccular lining 3 is reduced at the moment, and the liquid medium contained in the elastic saccular lining is squeezed out. When the conveying pipeline is cut off suddenly, the liquid medium in the conveying pipeline generates sudden momentum change to form a water hammer phenomenon. The compressed elastic saccular lining 3 can absorb the liquid medium into the inner cavity of the elastic saccular lining 3 due to the negative pressure, so that the water hammer is greatly reduced.
The principle that the elastic saccular lining 3 is in a negative pressure state in the flowing process of the liquid medium is as follows: the phenomenon is a common phenomenon of hydrodynamics, the pressure is small at a place with high speed, the pressure in the valve body 4 is small due to the flowing of a liquid medium, the pressure of the elastic bladder-shaped lining 3 is strong, and a pressure difference is formed between the two. The elastic bladder-like liner 3 is "deflated" by the atmospheric pressure in order to equalize the pressure with the valve body 4, and thus is reduced in volume and assumes a negative pressure state.
Example 2:
referring to fig. 1-4, the water-hammer-resistant constant flow valve comprises a valve body 4, wherein a plurality of laminar flow pipes 5 are installed in the valve body 4, and a plurality of mutually independent buffer oil storage grids are arranged on the outer side of the valve body 4 in a surrounding manner along the circumferential direction of the valve body 4; an elastic saccular lining 3 is arranged in the buffer oil storage grid, the inner cavity of the elastic saccular lining 3 is communicated with a pipeline of the valve body 4 through an oil discharge hole 7, and an air hole 10 communicated with the cavity of the buffer oil storage grid is arranged on the outer wall of the buffer oil storage grid.

Since the elastic bladder-like liner 3 is made of an elastic material such as rubber, it is not possible to connect the oil drain hole 7 by welding, and the reliability of the connection cannot be ensured by using a connection method such as an adhesive.
The elastic saccular liner 3 and the oil discharge hole 7 can be conveniently and firmly butted through the locking nut 9 and the sleeve 8. The installation steps are as follows: the locking nut 9 is firstly put into the inner cavity of the elastic saccular lining 3 from the opening of the elastic saccular lining 3, and then the opening of the elastic saccular lining 3 is aligned with the sleeve 8 so that the sleeve 8 is inserted into the inner cavity of the elastic saccular lining 3. Because the elastic saccular lining 3 is flexible, the locking nut can be pinched by hands from the outside to be tightly screwed with the sleeve 8, and the periphery of the screwed locking nut 9 can tightly press the periphery of the opening of the elastic saccular lining 3 to enable the elastic saccular lining to be in sealed butt joint with the sleeve 8.
Furthermore, the fixing rings 6 are arranged in a star shape, and the laminar flow pipes 5 are uniformly distributed in the valve body 4 in a star shape, so that the damage of liquid media to pipelines due to turbulent flow can be effectively reduced. The existence of the fixing ring 6 can enable the laminar flow pipe 5 to be arranged and installed outside the valve body 4, and then the laminar flow pipe is integrally placed inside the valve body 4 and then welded and fixed, so that the installation process and the installation difficulty are reduced.
Further, the air hole 10 is formed in the side baffle 2 of the buffer oil storage grid, and the air hole 10 is formed in the side face, so that dust and other impurities can be prevented from entering the buffer oil storage grid from the air hole 10.
Further, the two ends of the valve body 4 are provided with flanges 1, and the constant flow valve can be conveniently arranged on the conveying pipeline by utilizing the flanges 1.
The other parts of this embodiment are the same as embodiment 1, and are not described herein again.
The embodiment of the present invention is the above. The above embodiments and the specific parameters in the embodiments are only for the purpose of clearly showing the verification process of the utility model, and are not used to limit the patent protection scope of the utility model, the patent protection scope of the utility model is still subject to the claims, all the equivalent structural changes made by using the contents of the specification and the drawings of the utility model are included in the protection scope of the utility model.
