Description
Technical Field
The utility model relates to a water hammer is absorbed and is received ware technical field, specifically discloses a piston water hammer type is absorbed and is received ware.
Background
The piston type water hammer suction device is a device for absorbing residual water hammer pressure of a water supply system, in the water supply system, when a water pump fails or has power failure and the like, water flow is stopped suddenly and water hammer is generated when the water flow starts to flow backwards, at the moment, the water hammer can be buffered through a sealed air pressure cavity, a water power protection device capable of preventing a building water supply pipeline and facilities from being damaged by the water hammer can be used, when the water hammer enters the water hammer suction device, water hammer waves act on a piston, the piston moves towards the direction of an air containing cavity, the piston moves up and down under the double action of gas with certain pressure and irregular water hammer waves to form dynamic balance, and therefore irregular water hammer wave shock is eliminated on site.
However, after long-term use, the air pressure in the air containing cavity is easy to reduce, so that the water hammer wave eliminating effect is not good, at the moment, high-pressure air needs to be added into the air containing cavity immediately, so that the pressure gauge needs to be paid attention to all the time in the use process, and the labor intensity of workers is very high.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problem that the air pressure in the air cavity is easy to reduce after the traditional plug type water hammer type absorber is used for a long time.
In order to achieve the purpose, the basic scheme of the utility model provides a piston water hammer type absorber, which comprises a valve body, wherein one end of the valve body is provided with a flange plate, a first piston is arranged in the valve body in a sliding way, a plurality of auxiliary springs are fixedly connected between the first piston and the flange plate, and the other end of the valve body is communicated with an inflation valve and a barometer;
the other end of the valve body is fixedly connected with an inflation shell, a second piston is arranged in the inflation shell in a sliding mode, rubber sealing rings are arranged on the first piston and the second piston respectively, a plurality of push rods are fixedly connected between the first piston and the second piston and are arranged on the valve body in a sliding mode, the other end of the valve body is communicated with a first one-way valve, one end, close to the valve body, of the inflation shell is communicated with a second one-way valve and a pressure release valve, the gas outlet of the first one-way valve faces the valve body, and the gas outlet of the second one-way valve.
The principle and effect of this basic scheme lie in:
1. when the first piston is impacted by water shock waves in the valve body, the first piston can move up and down in the valve body to form dynamic balance so as to eliminate irregular water shock wave oscillation.
2. When first piston carried out up-and-down motion, the second piston alright also carried out up-and-down motion under the effect of push rod, and when the second piston up carried out reciprocating motion, the atmospheric pressure of second check valve entering mouth can be greater than the atmospheric pressure of gas outlet, consequently aerifys the outside gas of casing and just can get into in the gas chamber.
3. If the air pressure in the valve body drops, the second piston moves downwards again, and then the space of the air entering the air inflation shell can be compressed, so that the air is input into the valve body through the first one-way valve, and the air pressure in the valve body is kept stable.
4. If the air pressure in the valve body is at a normal value, the compressed air in the air charging shell is discharged out of the air charging shell through the pressure relief valve.
Further, a filtering cover is arranged at the air inlet of the second one-way valve. External dust is effectively prevented from entering the valve body.
Furthermore, a hanging ring is fixedly connected to the inflatable shell. The use comfort is improved.
Furthermore, the contact point of the valve body and the push rod is provided with a rubber sealing ring. Improve the stability in use, prevent that the gas in the valve body from getting into inflatable housing.
Furthermore, the joints of the valve body, the inflation valve, the barometer and the first one-way valve are coated with sealant, and the joints of the inflation shell, the pressure release valve and the second one-way valve are coated with sealant. The use stability is improved.
Furthermore, the auxiliary springs are coated with antirust paint. Effectively prevent the auxiliary spring from rusting.

Fig. 1 is a sectional view of a piston water hammer type inhaler according to an embodiment of the present invention.
Detailed Description
The following is further detailed by the specific embodiments:
reference numerals in the drawings of the specification include: the device comprises a flange plate 1, a valve body 2, a second one-way valve 3, a barometer 4, an inflation shell 5, a lifting ring 6, a second piston 7, an inflation valve 8, a pressure release valve 9, a first one-way valve 10, a push rod 11, a first piston 12 and an auxiliary spring 13.
The embodiment of the piston type water hammer type absorbing device is shown in figure 1, a flange plate 1 is welded at the lower end of a valve body 2, a first piston 12 is arranged in the valve body 2 in a sliding mode, four auxiliary springs 13 are welded between the first piston 12 and the flange plate 1, antirust paint is coated on the auxiliary springs 13, and an inflation valve 8 and a barometer 4 are communicated with the upper end of the valve body 2.
