Abstract
The utility model relates to a prevent check valve of solution crystallization in pipeline comprises valve body, disk seat, valve clack, rocking arm, valve gap, has the route that supplies the medium circulation in the valve body, and in the valve body was located to the disk seat, articulated on the valve body of disk seat top had the rocking arm, and fixed even has the valve clack on the rocking arm, is equipped with return nut on the side of being close to the valve clack that falls on the disk seat, and the valve clack falls the back lower part and lean on return nut and leave the clearance between the disk seat, valve body upper portion is equipped with the valve gap, and the valve gap passes through bolt and valve body rigid coupling, and the. The utility model discloses when using, weld the backflow nut on disk seat and valve clack sealing contact's face originally, make the check valve leave certain gap when closed, guarantee the copper sulfate solution in the pipeline under the condition of gravity smoothly flow back the holding vessel certainly, prevent the copper sulfate solution crystallization of reserving in the pipeline, also reduce the impact force that copper sulfate solution can flow in the twinkling of an eye in the pipeline and form to the delivery pump simultaneously, prolong the life-span of delivery pump.
Description
Technical Field
The utility model relates to the technical field of valves, especially, relate to a copper sulfate pipeline is with preventing crystal form check valve.
Background
In the electrolytic copper foil manufacturing process, a copper sulfate solution is a main production raw material, and the production process requires that the copper sulfate solution stored in a tank body is conveyed to a production facility through a copper sulfate piping system. However, the copper sulfate solution can be crystallized due to the temperature reduction at a certain concentration because of the special physical properties of the copper sulfate solution. When the delivery pump stops delivering copper sulfate, the check valve is closed, at the moment, copper sulfate solution is remained in the pipeline, the copper sulfate solution is often crystallized in the pipeline, the pipeline needs to be disassembled to clean internal crystals, the production efficiency is greatly influenced, and the check valve installation in the system is cancelled when a copper sulfate pipeline system is installed in some copper foil production plants, so that the safety of the whole pipeline system is reduced, and the pressure of liquid backflow in the pipeline brings damage to the pump per se at the moment of shutdown of the pump, so that the equipment maintenance cost is greatly increased, and the improvement is needed.
Disclosure of Invention
The utility model aims to solve the defects of the prior art and provides a copper sulfate pipeline anti-crystallization check valve.
The utility model discloses a realize above-mentioned purpose, adopt following technical scheme:
the utility model provides a prevent check valve of solution crystallization in pipeline, includes valve body, disk seat, valve clack, rocking arm, valve gap, has the route that supplies the medium circulation in the valve body, and in the valve body was located to the disk seat, articulated on the valve body of disk seat top had the rocking arm, and fixed the even there was the valve clack on the rocking arm, was equipped with return nut on the side of being close to the valve clack that falls on the disk seat, and the valve clack falls the back lower part and lean on return nut and leave the clearance between the disk seat, valve body upper portion is equipped with the valve gap, and the valve gap passes through bolt and.
And a sealing gasket is arranged between the valve cover and the valve body.
The backflow nut is welded on the valve seat.
The utility model has the advantages that: the utility model discloses an install the mode of check valve in copper sulfate pipeline, during the use with the vertical placing of check valve and the valve clack is located the backflow nut top, when the delivery pump stops carrying copper sulfate solution, the check valve can not be closed completely, remaining copper sulfate solution can slowly flow back in the pipeline and go into the jar internal, both make copper sulfate solution can flow back to the jar internal copper sulfate solution that avoids remaining in the pipeline and lead to the crystallization, when having avoided not installing the check valve again, copper sulfate solution flows back in the twinkling of an eye the great impact force that the jar body caused and damages the delivery pump, the life-span of delivery pump has been prolonged.

Fig. 1 is a schematic structural view of the present invention;
in the figure: 1-a valve body; 2-valve seat; 3-valve clack; 4-a rocker arm; 5-sealing gasket; 6-bolt; 7-screwing the nut; 8-valve cover; 9-a return nut;
the following detailed description will be made in conjunction with embodiments of the present invention with reference to the accompanying drawings.
Detailed Description
The invention will be further explained with reference to the following figures and examples:
as shown in fig. 1, a prevent check valve of solution crystallization in pipeline, including valve body 1, disk seat 2, valve clack 3, rocking arm 4, valve gap 8, there is the route that supplies the medium circulation in the valve body 1, in disk seat 2 located valve body 1, articulated on the valve body 1 of disk seat 2 top have rocking arm 4, fixed connection has valve clack 3 on rocking arm 4, is equipped with backflow nut 9 on the side of the valve seat 2 near the valve clack 3 that falls, valve clack 3 falls the back lower part and leans on backflow nut 9 and leave the clearance with disk seat 2 between, valve body 1 upper portion is equipped with valve gap 8, and valve gap 8 passes through bolt 6 and valve body 1 rigid coupling, and the end of bolt 6 is twisted soon has screw nut 7.
And a sealing gasket 5 is arranged between the valve cover 8 and the valve body 1.
The return nut 9 is welded to the valve seat 2.
The utility model discloses well back-flow nut 9 chooses the nut of the acidproof material that accords with the standard, and its size is confirmed according to the specification size of check valve.
The utility model discloses when using, with the vertical just valve clack 3 that place of check valve be located backflow nut 9 tops, weld backflow nut 9 on disk seat 2 and valve clack 3 face of sealing contact originally, make the check valve leave certain gap when closed, guarantee during copper sulfate solution in the pipeline flows back the holding vessel smoothly under the effect of gravity, prevent the crystallization of copper sulfate solution in the pipeline of reserving, also reduce the impact force that copper sulfate solution backward flow formed in the twinkling of an eye to the delivery pump in the pipeline simultaneously, prolong the life-span of delivery pump.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above embodiments, and various improvements made by the method concept and technical solution of the present invention or directly applied to other occasions without improvement are all within the protection scope of the present invention.
