Description

A dual-flow adjustable copper valve

technical field

The utility model relates to a double-flow adjustable copper valve, which belongs to the field of valves.

Background technique

A valve is a device used to control the direction, pressure, and flow of a fluid in a fluid system. It is a device that makes or stops the flow of media (liquid, gas, powder) in piping and equipment and controls its flow. The valve is a control component in the pipeline fluid conveying system, which is used to change the passage section and the flow direction of the medium, and has the functions of diversion, cut-off, throttling, check, diversion or overflow and pressure relief. Valves for fluid control, from the simplest globe valve to various valves used in extremely complex automatic control systems, have various varieties and specifications, and can be used to control water, steam, oil, gas, mud, various corrosive substances, etc. Various types of fluid flow such as media, liquid metals and radioactive fluids.

In people's daily life, valves are used more and more widely. The service life of some ordinary valves is short, it is not very convenient to replace and repair, and the sealing performance is not good. It is inconvenient to operate when the fluid is mixed, or the flow rate is not well controlled.

Utility model content

The problem to be solved by the utility model is that it is inconvenient to operate when two fluids are mixed, or the flow rate is not easy to control, so a dual-flow adjustable copper valve is provided.

In order to solve the above technical problems, the utility model provides the following technical solutions:

The utility model provides a dual-flow adjustable copper valve, which includes a valve body, the top of the valve body is a rotating valve handle, one side of the rotating valve handle is connected to a valve stem, and the bottom of the valve stem is connected to a cylindrical valve core. A bonnet is provided below the rotary valve handle, and the bonnet is connected to the valve body through screws. The cylindrical spool includes a through-hole section and a cut-off section, and the through-hole section is provided with a semicircular through-hole. The bottom of the valve body is connected to the valve seat, and the upper part of the valve seat is a groove, and a sealing ring is arranged on the groove.

As a preferred technical solution of the utility model, the rotary valve handle is connected to the valve stem through a pin shaft.

As a preferred technical solution of the utility model, the sealing ring is surfacing with alloy steel, and a spring is arranged at the bottom thereof.

As a preferred technical solution of the utility model, the valve body is made of copper, which has high strength and good corrosion resistance.

As a preferred technical solution of the utility model, the inner surface of the valve is provided with a sealing coating.

The beneficial effects achieved by the utility model are: the device provides a rotary valve handle that can be rotated manually, when the rotary valve handle is rotated, it drives the valve stem and the valve core to rotate, and the contact area between the semicircular through hole of the valve core and the pipe openings on both sides Change, so as to reasonably control the ratio of the flow at both ends. When the total flow needs to be reduced, press the rotating valve handle downward. Because the valve stem and the valve core move downward, the fluid outlet and the through hole will be misaligned, thereby reducing the total flow. Press the rotary valve handle directly to the bottom when not in use. The sealing ring is surfacing with alloy steel, so the valve will not produce too much wear when switching. At the same time, the copper valve has stable performance and durability, and is suitable for various occasions.

Detailed ways

The preferred embodiments of the present utility model are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present utility model, and are not intended to limit the present utility model.

Example 1

As shown in the figure, the utility model provides a dual-flow adjustable copper valve, which includes a valve body 1, which supports and protects the entire valve. The top of the valve body 1 is a rotary valve handle 3, and the rotary valve handle is a manual In the operation part, rotating the rotary valve handle 3 can control the different dispensing amounts of the two fluids, pulling up and down or pressing the rotary valve handle 3 can control the total fluid flow, one side of the rotary valve handle 3 is connected to the valve stem 4, and the valve stem 4 The bottom is connected with the cylindrical valve core 5, and the rotating valve handle 3 is connected to the valve stem 4 through the pin shaft 12, which can drive the valve stem 4 to rotate or move up and down, thereby driving the valve core 5 to rotate or move up and down. A bonnet 2 is arranged below, and the bonnet 2 plays a protective role on the valve stem 4 and the valve core 5. The bonnet 2 is connected with the valve body 1 through screws 101, and can be disassembled when the internal parts need to be replaced, thereby facilitating maintenance and follow-up. In other words, the cylindrical spool 5 includes a through-hole section 6 and a cut-off section 7. The through-hole section 6 acts as a guide for the fluid and can control the ratio of the fluid on both sides. The cut-off section 7 plays the role of cut-off. valves are used. The through-hole section 6 is provided with a semi-circular through-hole 8, and when the semi-circular through-hole 8 rotates with the valve core, its contact area with the pipe inlets on both sides changes, thereby controlling the different flows at both ends. The bottom of the valve body 1 is connected to the valve seat 9, the valve seat 9 plays the role of bottom support, the upper part of the valve seat 9 is a groove 10, and the groove 10 is provided with a sealing ring 11, when the valve needs to be closed , the cylindrical spool is pressed to the bottom groove to contact the sealing ring 11, and the sealing ring ensures that no fluid flows out.

The rotating valve handle 3 is connected to the valve stem through the pin shaft 12, and the rotating valve handle 3 can drive the valve stem 4 to rotate or move up and down through the pin shaft 12, thereby driving the valve core 5 to rotate or move up and down, and to control the different distributions of the two fluids. and total fluid flow. The sealing ring 11 is surfacing with alloy steel, so the valve will not cause too much wear when switching. There is a spring 14 at the bottom, so that the sealing ring and the valve core are tightly hugged together, and at the same time, the external force exceeds the preload of the spring. The switch is very light when pressed. The valve body 1 is made of copper, which has high strength and good corrosion resistance, which improves the service life of the valve. The inner surface of the valve body 1 has a sealing coating 13 to improve the sealing performance and prevent fluid leakage.

Specific working principle: The cylindrical spool 5 is driven by the rotating valve stem 4, and can rotate around the axis of the cylindrical spool 5 for the adjustment and control of the fluid ratio. The up and down movement of the rotating valve stem 4 drives the cylindrical spool. 5. Up and down movement controls the contact area with the outlet to control the flow rate. The valve can flexibly control the confluence, diversion, and flow direction switching of the medium on the pipeline. At the same time, it can also close any channel and connect the other two channels.

The beneficial effects achieved by the utility model are: the device provides a rotary valve handle that can be rotated manually, when the rotary valve handle is rotated, it drives the valve stem and the valve core to rotate, and the contact area between the semicircular through hole of the valve core and the pipe openings on both sides Change, so as to reasonably control the ratio of the flow at both ends. When the total flow needs to be reduced, press the rotating valve handle downward. Because the valve stem and the valve core move downward, the fluid outlet and the through hole will be misaligned, thereby reducing the total flow. Press the rotary valve handle directly to the bottom when not in use. The sealing ring is surfacing with alloy steel, so the valve will not produce too much wear when switching. At the same time, the copper valve has stable performance and durability, and is suitable for various occasions.
