Generally speaking, each pump should be installed with a bottom valve. The bottom valve is usually installed below the surface of the water. The initial performance is acceptable. Over time, due to the accumulation of silt and other debris, it is easy to cause the bottom. The valve is blocked, and even more, the water pump breaks the bottom valve under the action of the water hammer, causing the water pump to be difficult to drain water. After the water is drawn, the bottom valve is not closed tightly and it is easy to run water. It is also necessary to repeat the drainage or bring up the bottom valve for maintenance. It is difficult to solve the problem. For the general situation, the pump does not produce water. After solving problems such as impeller wear and plugging and pipe leakage, all problems can be solved. For example, if there is no water, the bottom valve is mostly blocked. At this time, it takes some human and material resources to drain the pool or propose The bottom valve can be repaired, and for the pumps that work on most occasions, it must be ensured that the pump is turned on. What method is used to solve the problem of easy plugging of underwater bottom valves?
A simple and easy method is to use a water bottom valve to abandon the old underwater bottom valve. As the name suggests, it is installed above the water. It is an updated product of the old-fashioned bottom valve. It is an ideal water diversion device, and it also replaces the vacuum pump and vacuum pumping device.
Features:
1. Substituting underwater bottom valve and 90° turning place on the horizontal pipe and water inlet pipe above the water surface, it can also replace the elbow. Its sealing performance is unique, it can reach the dripping water without leakage, and it has a damping device, which has certain harm to the water hammer. The mitigation effect.
2. Significant energy saving effect. When used normally (in kilotons/meter power consumption), it can save energy by about 5-7%. After one to two years of use, the electricity cost can be recovered and your investment cost for purchasing this valve can be recovered. The effect is that the general bottom valve cannot reach.
3, long service life, easy maintenance, the service life of the bottom valve more than five years, greatly reducing the production costs, and in the use of the general period there is no failure, even if there is a failure, handling is extremely convenient and rapid. Fully demonstrated its superiority.
4, self-priming performance is reliable, as we all know, the old bottom valve sealing performance is poor, often there will be no water after the pump can stop the problem, and the water bottom valve has a unique sealing effect, can be achieved without leakage, to ensure that the next pump In the process of design, it is not necessary to consider the selection of a large-scale investment project for submerged pump room water supply because the pump does not emit water.
5, the product connection flange in full compliance with GB regulations, good general performance.
Instructions for use:
1. Specifications: DN50, DN65, DN80, DN100, DN125, DN150, DN200, DN250, DN300, DN400, DN500, DN600, DN700, DN800DN900DN1000 and other specifications.
2. Nominal pressure: 0.6-1.0-1.6MPa
3, installation requirements: installed in the water pump suction pipe vertical pipe and horizontal pipe corner, the installation should ensure that the vertical state.
4. Start-up: Immediately after the first start, the horizontal pipe is fully filled with water and starts immediately. This causes the suction pipe to be in a semi-vacuum state and the water is sucked into the vertical pipe to complete the pumping process. When the suction process is too large, it is necessary to repeat the start of water filling several times. Afterwards, stop the pump and do not have to fill the water before starting the pump.
5, maintenance: Under normal circumstances do not have to repair. When maintenance is required, only the valve cover above the water-type bottom valve should be opened, and the rubber pad can be replaced. After the maintenance, the valve is started according to the first time.
6, if used in the high concentration of the fluid, please use stainless steel water bottom valve, at the same time we can produce all plastic water bottom valve or 316L (molybdenum titanium) material water type Bottom valve

The main type of Tape Measure is Steel Tape, followed by fiber tape, which is the tape that everyone often sees. Many people say it is a cloth ruler, and there is also a waist measurement ruler (tailor ruler/clothing ruler belong to this category). In southern China and Hong Kong, the tape measure is usually referred to as a soft ruler or a pull ruler. The material is PVC plastic and glass fiber, which can prevent the tape from being stretched during use.
