Description

Water control valve

The present invention relates to a dilution valve device, and more particularly, to further improve the pre-registration patent registration No. 284454 and the patent registration 10-758995 of the present invention to facilitate the lifting and lowering of the valve disc for opening and closing the flow path The resistance and abrasion of the screw fastening part can be reduced to prolong the service life of the screw, and the height of the valve device can be significantly lowered.

In general, the water discharge valve device is installed in a pipe through which various fluids flow, such as water and sewage pipes or oil pipes, and used to control fluids flowing at high pressure and high speed.

Looking at the conventional structure of the water separator valve device that plays such an important role, the valve disk for opening and closing the oil pipe and the sheet that is attached to the outer circumferential surface of each of them is separately made of different materials and then heat-sealed them. Since it had to be attached in one piece by using various methods such as manufacturing, the production was cumbersome and difficult, and there was a problem in that the productivity was lowered. Since it is connected and installed using the connection means of the vehicle, when a strong external shock is applied to the body of the valve device during transport or installation, it is separated from each other by the impact and the valve disc cannot be operated. There was this.

On the other hand, the valve rod, which is installed to protrude vertically above the valve disc, is exposed to the outside, and the part is corroded, bent or cut due to various factors such as inadvertent operation or neglect of management. Occurrences often occurred.

Thus, in view of the above-mentioned conventional problems, there is a patent registration No. 284454, which is a pre-registered invention of the applicant of the present invention, which is provided with a valve casing having a flow passage formed in both directions and an entrance on the upper side, and the valve casing. A valve disc is provided to open and close the flow path while being lifted toward the doorway, and a valve rod protruding toward the doorway is integrally formed with the valve disc at the upper end of the valve disc, and is rotatably formed at the top of the doorway. The sleeve nut is wrapped so as not to be exposed to the outside is screwed with the valve rod is configured to open and close the valve disc in a state that the valve rod is not exposed out of the valve casing as the valve rod is raised and lowered in accordance with the rotation of the sleeve nut.

Such a pre-registered invention of the present invention forms the valve disc and the valve rod integrally, and the valve disc is manufactured in a shell-mould manner, thereby eliminating the need for additional mounting of the valve seat. By coupling the formed valve rod with the sleeve nut and sealing the upper part of the sleeve nut with a handle cap to integrate the valve rod, the valve rod is not exposed to the outside and thus durability is improved.

However, in spite of the above advantages, since the bottom contact surface of the sleeve nut and the slide contact surface of the cover that slides on the bottom surface of the sleeve nut are in contact with each other, the contact area is very wide and the sleeve nut rotates due to increased frictional force. It is not smooth and the wear of the screwing part is accelerated due to the frictional wear, which affects the life of the product.In the case of lifting the valve disc by rotating the sleeve nut, the valve disc and the upper side thereof are integrated. As the connection part of the valve rod protruding from the valve rod is tightly inserted into the inner surface of the valve rod coupling hole formed in the center of the bottom of the sleeve nut, the sleeve nut is no longer rotated and does not move.

Accordingly, the applicant of the present invention, as shown in Patent Registration No. 10-758995 and FIG. 1, the bottom surface of the sleeve nut 110 embedded in the valve body 100 and the bottom surface of the sleeve nut 110 are seated and slide. The slide contact surface of the cover to be in a line contact state by minimizing the friction between each other to smooth the rotation of the sleeve nut 110, reducing the wear caused by the friction force to ensure the long life of the product, as well as the valve Connection of the valve rod 121 at the time of elevating the valve disc 120 by coupling the rotatable stopper ring 130 that is rotatable to the outer surface of the lower connection portion of the valve rod 121 integrally protruding from the upper side of the disc 120. It is configured so that the portion does not get caught in the valve rod coupling hole formed at the center of the bottom of the sleeve nut 110 so that the phenomenon that the sleeve nut is tightly prevented from rotating anymore is completely prevented. As a result, the distillation valve device was designed to be used conveniently for a long time without damage or failure of the distillation valve device.

However, the existing conventional water valve device having the above structure has a structure in which the valve rod and the valve disc are lifted up and down according to the rotational action of the sleeve nut, so that the valve device is opened and closed by the valve disc as described above. In operation, the sleeve nut has a problem that the weight of the valve rod and the valve disc work together, thereby shortening the service life of the valve device.

That is, the sleeve nut is formed with a female screw portion having a lower open shape, and the female screw portion is screwed with a valve rod integrally coupled with a valve disc. Thus, the weight of the valve rod and the valve of the female nut portion of the sleeve nut are screwed. The weight of the disc acts simultaneously. Accordingly, when the sleeve nut is rotated, the weight of the valve rod and the valve disc is transmitted to the threaded joints, thereby generating considerable resistance and friction to the screwed joints.

Therefore, the resistance and frictional force as described above is to cause a serious wear of the screw portion and to act as a cause of shortening the service life for these screw fastening portion.

In particular, since the weight acting on the screw fastening part will affect the rotational force of the sleeve nut, a strong rotational force must be applied to rotate the sleeve nut even when the valve device is to be opened or closed through the rotational action of the sleeve nut. The inconvenience of use is also very big.

In addition, both the above-described water discharge valve device and the existing conventional valve device has a closed end manufactured with an excessively large height, which is to receive the valve disc completely inside the doorway formed to protrude upward from the valve body. This is because the female thread portion must be formed and protruded so that the male thread portion of the working rod can be accommodated above the entrance, and the excessive height is increased for the water valve device. Due to this situation, problems are continuously occurring during the fastening and installation of the valve device.

The present invention is to solve the problems as described above, a male screw portion is formed on the lower side of the valve rod, and the valve disk manufactured separately from the valve rod to form a vertical insertion hole having a female screw portion at the tip, The tip is formed by integrally forming the handle cap,

When the valve rod is rotated, the valve rod is lifted and lifted while the weight of the valve disc is acting on the valve rod. Therefore, the wear on the screw coupling portion is relatively reduced, and the lower end of the valve rod is directly screwed onto the valve disc. Therefore, it is an object of the present invention to provide a water-reducing valve device capable of reducing the overall height of the valve device to produce a valve device in a more reduced state without loss of flow rate.

The present invention for achieving the object as described above, is provided with a valve casing having a flow path pipe formed in both directions and the upper portion, the valve disk for opening and closing the flow pipe while being elevated to the entrance to the inside of the valve casing is provided A valve rod protruding toward an entrance is located above the valve disc, and the valve rod is coupled to be rotatable by a cover fastened to an upper entrance of the valve disc. In the fresh water valve device for allowing the disk to be raised and lowered inside the valve casing,

The valve disc is a vertical coupling hole is formed and the upper side of the coupling hole is formed by forming a female screw, the valve rod is formed at the tip of the handle cap integrally protruding and the lower side of the handle cap between the entrance and the cover A locking jaw that is constrained to the lower side of the locking jaw and is formed into a male screw portion which is screwed to the female screw portion while being inserted into the coupling hole of the valve disc, thereby rotating the valve rod constrained in a rotatable state by the valve casing and cover. In accordance with the direction of the valve disc is screwed up and down in the upward and downward direction is configured to open and close the flow pipe of the valve casing.

According to the present invention, since only the weight of the valve disc acts on the valve rod of the dividing valve, the rotation of the valve rod is made smoother and easier, and the load between the valve rod and the valve disc decreases as the load acting on the valve rod decreases. The service life is greatly extended due to the reduction of wear rate on the screw connection part, and the overall height of the valve device is significantly reduced through the direct screw coupling structure of the valve rod and the valve disc, thereby providing a simplified valve device without changing the flow rate. It is very economical and reasonable effect.

The terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary meanings and the inventor may properly define the concept of the term to describe its invention in the best possible way And should be construed in accordance with the principles and meanings and concepts consistent with the technical idea of the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is an exploded perspective view of main parts of a water separator valve device according to the present invention, FIG. 3 is an overall cross-sectional view of the water separator valve device according to the present invention, and FIG. 4 is a cross-sectional view of an open state of the water separator valve device according to the present invention.

As shown in the drawing, in the water-removal valve device according to the present invention, a flow path tube 11 through which fluid flows is formed on both sides, and a valve in which an inlet 12 is integrally formed above the center of these flow path pipes 11. Casing 10, but the inside of the valve casing 10 has a plate-shaped valve disk 20 is built in the flow path tube (20) while the valve disk 20 is elevated in the direction of the entrance (12) ( 11) will be in charge of opening and closing.

At this time, the coupling hole 21 is formed in the valve disc 20 vertically, and the female screw portion 22 is formed above the coupling hole 21.

In addition, a separate cover 40 is fastened to an upper side of the inlet 12 of the valve casing 10, and a separate valve rod 30 is connected to the inlet and outlet by using the cover 40 and the inlet 12. When coupled to the valve disk 20 from the inside of the (12) is coupled to the valve rod 30 in a rotatable state.

That is, the valve rod 30 is a handle cap 31 of the chamfered form is integrally formed so as to fasten a separate handle (not shown in the figure) to the front end, the lower side of the handle cap 31 The locking jaw 32 having an outer diameter larger than the outer diameter of the valve rod 30 is formed to protrude, and the male screw portion 33 is formed on the outer surface of the valve rod 30 below the locking jaw 32. .

Accordingly, the handle cap 31 is exposed upward through the cover 40, and the locking jaw 32 is locked between the upper portion of the doorway 12 and the lower portion of the cover 40. The free rotation of the rod 30 is made, and the male screw portion 33 of the valve rod 30 is screwed together with the female screw portion 22 of the valve disc 20.

At this time, the coupling hole 21 of the valve disc 20 should be formed with an inner diameter such that the male screw portion 33 of the valve rod 30 can be inserted, the groove from the upper side of the valve disc 20 It can be manufactured in the form of a vertical or through, in the case of manufacturing the coupling hole 21 in the form of the vertical through, the lower end of the valve rod 30 is to protrude through the lower side of the valve disc 20 In this case, the overall height for the valve device will be further lowered, so it will have the advantage of being manufactured.

Therefore, when the valve disc 20 completely blocks the inside of the flow path tube 11 in the coupled state as described above, the fluid to be flowed along the flow path tube 11 is blocked, and the valve rod 30 is closed. When the valve disk 20 is screwed up by the rotation, the flow of the fluid is made while the flow passage 11 is gradually opened naturally.

At this time, the valve disk 20 is a non-rotating lifting body by the state of being locked to the guide groove (not shown in the figure), etc. in the flow path pipe 11 as is well known, so that the valve rod 30 When the rotation is made, the valve disc 20 is to be raised in accordance with the screw coupling structure in a non-rotating state. On the contrary, when the direction of rotation with respect to the valve rod 30 is reversed, the valve disc 20 in the up state is lowered to seal the flow pipe 11.

Thus, since the valve rod 30 is screwed directly to the valve disc 20, only the weight of the valve disc 20 acts on the valve rod 30, so that the female screw portion 22 and the male thread 22 may be formed. In the screw fastening portion by the screw portion 33, wear and friction resistance is significantly reduced compared to the conventional valve due to the small weight. This reduction in wear and friction resistance will eventually lead to a smooth and easy rotational action of the valve rod 30, leading to an extension of the service life for the screw connection.

In addition, the present invention is a very efficient and can be produced significantly reduced compared to the existing various valve device, as described above, the valve device of the present invention, the valve disk 20 is the male screw portion of the valve rod 30 It has a structure that is directly fastened up and down along the (33) so that the entrance (12) can be operated only if it is manufactured to a height corresponding to the outer diameter of the valve disk 20, so as to form unnecessary height space in the existing valve device It is not necessary.

That is, as shown in FIG. 5, the valve device of the present invention secures only the height H1 of the valve disc 20 and the height H2 of the inlet and outlet 12 for accommodating the valve disc 20. If only the part is made to protrude, smooth operation will be possible, but the existing valve device can accommodate the height h1 of the valve disc, the height h2 of the entrance and the valve rod fixed integrally to the valve disc to accommodate the valve disc. Since the height h3 by the sleeve nut having a space so as to be essentially required to be provided, eventually has a structure that the overall height is higher than the valve device of the present invention.

Accordingly, the valve device of the present invention can significantly reduce the height of the entire valve while maintaining the flow rate of the flow rate as it is possible to reduce the overall size of the valve equipment as well as the restriction on the installation space of the valve is relatively reduced It is also advantageous in terms of installation, maintenance and repair.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the present invention as defined by the appended claims. Examples should be understood.
