Description

Easy-to-Operate Pipe Angle Valve {AN EASILY OPERATABLE PIPE MOUNTED ANGLE VALVE}

The present invention relates to an angle valve with a pipe, and more specifically, to form a screw position that directly switches the handle of a valve for opening and closing a pipe to a handle so that the diameter of the thread can be made larger, and thus, It relates to an easy-to-operate pipe angle valve that improves durability by making the opening and closing action more easily by gaining, and preventing excessive force from being applied to the sealing material when water supply is cut off.

In general, a pipe angle valve is one of the piping materials installed in a water pipe embedded in an interior wall of a building to use tap water indoors, and one end thereof is connected to a water pipe embedded in a wall. The valve is built in to block and supply the water, and the tap water flows in a 90-degree direction, and serves to supply tap water to the water tank or shower of the toilet.

Such a conventional pipe angle valve is disclosed in Patent Publication No. 10-2006-0129998.

6 is a cross-sectional view showing the configuration of a conventional angle valve, Figure 7 is a cross-sectional view showing the flow of water in the open state of Figure 6, the pipe angle valve (1) and the water pipe connection portion 11 is connected to the buried water pipe The T-shaped main body 10 including the water outlet 13 and the valve inlet 15 and the flow path opening and closing valve 30 between the water pipe connection portion and the water outlet are provided.

The main body 10 having the screw 16 formed on the inner circumferential surface of the valve inlet 15, the valve portion 33 on which the disc packing 31 is mounted at the distal end, and the spindle portion 35 provided with the screw 36 on the outer circumferential surface thereof. Is integrally formed and the spindle 30 has a fastening hole 39 formed outside the valve 30, the center of the spindle coupling hole 51 corresponding to the screw 36 of the valve 30 through Bidirectional nut 50 and the valve 30 are formed on the outer circumferential surface is formed with a main body engaging portion 53 corresponding to the screw 16 of the main body and a locking end 55 for restricting entry to the main body. The cover of the valve inlet 15 and the bi-directional nut 50 of the body and the handle which is integrally fastened to the valve 30 through the fastening screw 40 coupled to the fastening hole 39 to rotate the opening and closing operation. It is configured to include a sleeve-like handle 70 also serves.

One of the screw 16 formed at the valve inlet of the main body 10 and the screw 36 formed on the outer circumferential surface of the spindle 35 of the valve 30 is formed with a left screw and the other with a right screw. Screws of the spindle coupling hole 51 and the body coupling portion 53 of 50 are also formed correspondingly.

However, in the conventional valve structure as described above, the water must be shut off by pushing the valve corresponding to the direction in which water is supplied, that is, the direction in which the water pressure acts in order to shut off the water supply.

That is, since the force applied to the hydraulic pressure is supported by the thread 36, it is necessary to increase the size of the thread, and when the size of the thread is increased, the diameter of the spindle becomes smaller, so that the rotation of the handle 70 There is a risk of damage, and there is a risk of failure. In addition, if the spindle is made of a material other than metal, that is, plastics, the risk becomes more severe.

Therefore, the sealability is remarkably deteriorated due to the mechanical structure, and since the linear motion for opening and closing the valve 30 is moved by the thread distance of the screw 36 formed on the outer circumferential surface of the spindle, the valve does not open until the knob 70 is rotated several times. In particular, since the conveyance distance of the valve spindle for opening and closing the valve must be long, the overall specification must be increased, which in turn increases the manufacturing cost, and because the diameter of the threaded spindle is smaller, the inclination of the thread becomes larger. Since the acting pressure is large, there is a problem in that it is easily worn and a relatively large force is required.

In addition, the screw thread is formed directly on the nut 50 coupled to the outer circumferential surface of the spindle portion 35 and the valve inlet of the main body 10 for opening and closing of the valve. The contact area is small.

Therefore, the valve's water pressure is concentrated in the area where the contact area of the interacting thread is small. Therefore, the spindle formed with the thread must be made of metal, which is a strong material. There was a problem causing the defect.

In the present invention for improving the above problems, the reaction force of the hydraulic pressure acting during the opening and closing action of the valve is more widely distributed, and the easy-to-operate pipe angle to make the opening and closing action more smoothly with a small force when the handle is rotated. The purpose is to provide a valve.

The present invention for achieving the above object is obtained on one side; Water outlet and; An angle valve body having a handle for controlling the valve device to open and close the inlet and outlet, wherein the handle of the angle valve body has a body outer diameter screw threaded to the outside of the body and a body inner diameter of the thread formed inside the body A sealing member having a screw and having a coupling screw formed on an outer circumferential surface thereof to be coupled by a body inner diameter screw of the handle portion, and a sealing member having a smooth parallel cylindrical surface formed on an inner circumferential surface thereof; A spindle inserted into the parallel cylindrical surface of the sealing member and provided with a leakage preventing sealing portion O-ring for rotating and linear movement along the cylindrical surface, and a pipe opening / closing sealing portion O-ring for opening and closing the pipeline of the angle valve body; ; The handle engaging portion of the spindle is inserted into the spindle coupling groove is integrally coupled and fixed, characterized in that it consists of a handle provided with a handle inner diameter screw to engage the outer diameter screw to the body to rotate and linear movement.

In the present invention, the sealing member is provided with a plurality of leak-proof sealing O-ring is characterized in that it is closely coupled to the inner peripheral surface of the angle valve body.

In the present invention, the handle and the spindle is made of different materials, characterized in that coupled to the integral by the spindle coupling screw.

This embodiment of the present invention by forming a screw thread on the inner surface of the handle having a larger diameter and the outer circumferential surface portion of the angle valve body without forming a thread on the spindle that opens and closes the valve, the screw thread is relatively compared to the conventional angle valve By forming a large diameter, the inclination of the screw thread is minimized to enable finer valve intermittent function, and the valve can be opened and closed with a smaller force to enable a more precise valve opening and closing function.

In addition, in the case of the conventional angle valve, because the impact of the thread due to the hydraulic pressure in the spindle, or the force required to block the water by rotating the handle is large, durability must be used only by using a strong material such as metal, but the present invention is a metal It is also possible to apply a weaker material may have a variety of designs.
