Description

Technical Field

[0001] The utility model relates to the technical field of multi-way copper valves, in particular to an adjustable multi-way copper valve. Background Art

[0002] Copper valves are copper-cast valves, which are industrial parts. The earliest manufacturing process was developed in Ningbo, Zhejiang Province, China. The sand casting process was initially used in the manufacturing process. In the early 1990s, it was changed to forging process. By the beginning of the 21st century, China had developed into the world's copper valve manufacturing center. The maximum allowable working pressure in the valve technical parameters refers to the working pressure at room temperature, and the mechanical strength of the valve material decreases with the increase of temperature, so the allowable working pressure of the valve will decrease with the increase of the medium temperature;

[0003] As shown in the reference case "An adjustable multi-way copper valve" announcement number "CN220378945U", through the coordinated use of the multi-way copper valve body, valve body, annular connector, gland, knob, arc-shaped slideway and slider, the valve stem is placed in a relatively closed space formed by the annular connector, gland and valve body, avoiding direct contact between the valve stem and the outside world. The valve stem is indirectly operated by operating the knob to achieve the opening and closing effect of the multi-way copper valve body, solving the problem that the valve stem is partially exposed to the outside of the valve body structure and is easily exposed to dust and moisture from the outside, increasing the probability of rust and corrosion of the valve stem and greatly reducing its service life;

[0004] The protective parts of the valve stem are prone to physical wear or material degradation under long-term use and environmental exposure. These damages will cause the performance of the protective parts to decline and affect the protective effect.

[0005] Therefore, an adjustable multi-way copper valve is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide an adjustable multi-way copper valve in order to solve the above-mentioned problems, thereby improving the protective components of the valve stem. Under the condition of long-term use and environmental exposure, the protective components of the valve stem are prone to physical wear or material degradation. These damages will cause the performance of the protective components to decline, affecting the protective effect.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: an adjustable multi-way copper valve, comprising: a multi-way valve body, a valve stem is rotatably mounted on one side of the multi-way valve body, and two driving plates are arranged on both sides of the valve stem;

[0013] Preferably, a limit ring is fixedly installed on the inner wall of the sealing cover, and the limit ring is in contact with one end of the sealing tube away from the multi-way valve body. A spring is installed between the sealing plate and the surface of the multi-way valve body. When the sealing cover drives the valve stem to rotate, the limit ring can be stably sleeved on one end of the sealing tube through the limit ring. The limit ring serves as a positioning component to ensure a stable connection between the sealing tube and the sealing cover.
