The balance valve is a valve with special functions. There is nothing special about the valve itself, the only difference lies in the function and place of use. In some industries, due to the large pressure difference or flow difference of the medium (all kinds of flowable substances) in various parts of the pipeline or container, in order to reduce or balance the difference, between the corresponding pipelines or containers A valve is installed to adjust the relative balance of the pressure on both sides, or to achieve flow balance through the method of shunting. The valve is called a balance valve.

The quality of the balance valve used at this stage is relatively poor, especially the internal valve core is prone to damage when subjected to high pressure and soaking for a long time, resulting in problems with the internal sealing of the balance valve, and the ability to adjust pressure and flow is reduced. Therefore, for the existing technology We need to innovate the existing technology.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figure 1-2, the utility model provides a technical solution: a brass balance valve, including a balance valve main body 1, water outlet 2, water inlet 3, pressure balance chamber 4, rotating shaft 5, knob 6, pressure Air chamber 7, inflation knob 8, pressure relief knob 9, water valve baffle 10, water flow channel 11, spherical valve core 12, piston 13, pressure adjustment chamber 14, pressure air chamber 15, spring 16, adjustment seat 17 and screw rod 18. The left side of the balance valve main body 1 is provided with a water outlet 2. The balance valve main body 1 is integrally cast with brass material, which can stabilize the structure of the device and prevent seal damage and leakage after long-term use. The right end of the balance valve body 1 is provided with a water inlet 3, and the upper side of the balance valve body 1 is provided with a pressure balance chamber 4, and the upper side of the pressure balance chamber 4 is connected to the knob 6 through a rotating shaft 5, and the pressure balance chamber 4 There is a pressure chamber 7 on the left side, an inflation knob 8 is arranged on the upper side of the pressure chamber 7, a pressure relief knob 9 is arranged on the left side of the inflation knob 8, and a water valve stopper is arranged inside the balance valve body 1 Plate 10, the water valve baffle plate 10 is provided with a water flow channel 11, the water flow channel 11 is provided with a sealing rubber ring, which can effectively ensure the interception of the water flow, and the upper right corner of the water flow channel 11 is provided with a spherical valve core 12. The upper side of the spherical valve core 12 is connected to the piston 13, the piston 13 is set in the pressure regulating chamber 14, the left side of the pressure regulating chamber 14 is connected to the pressure gas chamber 15, and the pressure gas chamber 15 passes the pressure The tube is connected to the pressure regulating chamber 14, and a waterproof piston is provided in the pressure pipe, which can prevent moisture from entering the interior of the pressure regulating chamber 14 and corrode the internal parts. The piston 13 is connected to the regulating seat 17 through a spring 16, and the regulating seat 17 is set On the screw rod 18, the piston 13 is sleeved on the screw rod 18, and is slidably connected with the screw rod 18, so as to ensure the stability of the piston 13 so that it will not deviate left and right.

Working principle: When using the brass balance valve, the device can be installed at the junction of the main pipeline and the branch, and the knob 6 can be turned to control the position of the adjustment seat 17, so that the spring 16 can be relaxed, so as to control the preset pressure value , when in use, it can ensure that the pressure of the tributary is always the same. When the pressure increases, moisture will enter the pressure air chamber 15, increasing the pressure in the pressure air chamber 15, and then increasing the pressure in the pressure regulating chamber 14.
