Description

Gas-liquid separation valve for water pump replenishment system

technical field

The invention provides a gas-liquid separation valve in a water supply system of a water pump, which is mainly used for water supply of a reciprocating water pump. Specifically, it is the gas-liquid separation valve of the water pump replenishment system.

Background technique

The existing water replenishment technical scheme of the water pump supply system is: the input end of the water replenishment pump is connected with the water tank, and the output end of the water replenishment pump is connected with the system or equipment through the pipeline, and then the water replenishment is performed. However, in the actual process of replenishing water, there is often a phenomenon that the water cannot be replenished, and the vibration and noise of the replenishing pump are also relatively large. The cause of the fault cannot be found even if the replenishing pump is disassembled; clogged place. Due to the inability to replenish water, the temperature of the water in the replenishment pump will rise sharply under the action of the continuous operation of the replenishment pump, and the pump body will become hot. In severe cases, the replenishment pump will be stuck, which will endanger the safe operation of high-temperature and high-pressure equipment. . Through repeated dismantling, it was found that the gas inside the water replenishment system accumulated in the pipeline at the outlet of the water replenishment pump. At the same time, when the gas accumulated, the water replenishment pump generated large vibration and noise during operation, which caused this failure phenomenon. Therefore, the existing water replenishment system technology The scheme poses hidden dangers to the safe operation of the equipment.

Contents of the invention

In order to solve the fault problem of poor water replenishment in the existing water pump supply system, the invention provides a gas-liquid separation valve for the water pump water replenishment system. The liquid water output by the gas-liquid separation valve enters the inlet port of the gas-liquid separation valve through the water supply pump, and the gas-liquid separation is carried out in the gas collection chamber and gathered at the top of the gas collection chamber. Entering the gas-liquid separation chamber, the liquid water enters the water pump water replenishment system through the liquid outlet of the valve, solving the technical problem of water replenishment in the water pump supply system.

The scheme that the present invention solves technical problem adopts is:

The lower part of the cylindrical hollow valve body is provided with a lower end cover, the end face of the lower end cover is centered with a liquid inlet port, the upper part of the valve body is provided with an upper end cover, and the upper and lower end covers are respectively provided with sealing rings at the joints of the valve body. There is a liquid outlet port on the side of the lower part of the body, and a dish-shaped downward air-collecting chamber partition is arranged inside the valve body. A slender shaft-shaped guide rod is arranged between them.

The air-collecting chamber partition divides the inner cavity of the valve into two chambers, the upper chamber is a gas-liquid separation chamber, and the lower chamber is an air-collecting chamber.

The upper end of the guide rod is fixedly connected to the center of the upper end cover, and an opening and closing spring is installed downward on the guide rod.

A venting cock is provided at the eccentric outside of the upper end cover.

The inner center of the lower end cover is provided with a water baffle, and the lower end cover is rotated so that the plane of the water baffle is perpendicular to the center of the liquid outlet, and the water baffle is arranged between the liquid outlet and the liquid inlet.

Positive effect, since the liquid water output by the water replenishing pump enters the inlet port of the gas-liquid separation valve in the present invention, the gas-liquid is separated in the gas-collecting chamber and gathered at the top of the gas-collecting chamber, the pressure generated when the water replenishing pump replenishes water opens the ball head of the valve, The gas enters the gas-liquid separation chamber, and the liquid water enters the water pump water replenishment system through the liquid outlet of the valve, which solves the current situation that the water replenishment pump cannot replenish water. The structure is simple, the installation is convenient, and the potential safety hazard of the equipment is reduced. It is suitable for application as a gas-liquid separation valve.

Detailed ways

As shown in the figure, a lower end cover 14 is arranged on the lower part of the cylindrical hollow valve body 4, and a liquid inlet port 10 is arranged on the center of the end surface of the lower end cover, and an upper end cover 15 is arranged on the upper part of the valve body. Sealing rings 16 are provided at the joints, a liquid outlet port 12 is provided on the lower side of the valve body, a disk-shaped downward gas-collecting chamber partition 8 is arranged inside the valve body, and a valve ball is provided at the upper center of the gas-collecting chamber partition. Seat 7 is provided with elongated shaft-shaped guide rod 2 between the inner side of the upper end cover and the partition plate of the gas collection chamber.

The air-collecting chamber partition divides the inner cavity of the valve into two chambers, the upper chamber is the gas-liquid separation chamber 13 , and the lower chamber is the air-collecting chamber 9 .

The upper end of the guide rod is fixedly connected to the center of the upper end cover, and the opening and closing spring 3 is installed downward on the guide rod, and the lower end of the guide rod is provided with a valve ball head 5 to block on the valve ball seat, and is connected and fixed together by a lock nut 6 .

Work process and characteristics of the present invention:

When the supplementary pump supplies water to the system, the output of the supplementary pump is connected to the liquid inlet of the gas-liquid separation valve, and the liquid water enters the inlet of the gas-liquid separation valve and separates water and gas inside the separation valve. Under the pressure, the gas rises to the top of the gas collection chamber, the valve ball head is under pressure, the gas enters the gas-liquid separation chamber, and the liquid water enters the water supply system through the liquid outlet port of the gas-liquid separation valve. When the water replenishment system stops replenishing water, the opening and closing spring closes the ball head of the valve, and the diaphragm of the gas collection chamber seals the water retaining plate tightly, so that the gas stays in the gas-liquid separation chamber and cannot enter the system.

During the daily maintenance of the pump water supply system, the problem of water supply can be solved by opening the threaded vent cock to check the internal gas.
