Abstract

The utility model relates to a pressure reducing device, in particular to a pressure reducing device of a water hammer, which includes a cylinder, a piston, an air tap and a spring, wherein one end of the cylinder is opened and the other end thereof is sealed, a spring is arranged inside the one sealed end of the cylinder, a piston is arranged at one opened end of the cylinder and arranged in the cylinder, and the external part of one sealed end of the cylinder is connected with the air tap. The pressure reducing device has the advantages of simple structure, novelty and practicality.

Description

A kind of water hammer pressure slows down device
Technical field
The utility model relates to a kind of pressure relieving device, and particularly a kind of water hammer pressure slows down device.
Technical background
Water hammer is the instantaneous pressure that produces under the situation of opening suddenly or cutting out in the water route, when closing water tap, the low layer of high building or the bigger place of hydraulic pressure can feel that the sound of impact of water hammer water pipe, this pressure that is produced by water hammer often cause that water pipe breaks, joint comes off.
Summary of the invention
The utility model is intended to overcome the defective of prior art, slows down the destruction of water hammer to water system, provides a kind of simple in structure, easy for installation, and the water hammer pressure that using effect is good slows down device.
Water hammer pressure described in the utility model slows down device, form by cylinder body, piston, valve and spring, the sealing of cylinder body one end opening one end, inside at the airtight end of cylinder body is placed with spring, one end of cylinder body opening has piston to place in the cylinder body, this spring is extrapolated with piston, and an end that seals at cylinder body is externally connected to valve.
The airtight end of cylinder body described in the utility model is equipped with valve, is pressed into air by valve in cylinder body, and piston is extrapolated.
Cylinder body opening one end of described model utility is connected with water pipe, and when water hammer pressure produced, water hammer pressure promoted piston and moves, and moving of piston also has resistance, and this resistance promotes moving of piston, has slowed down the harm of water hammer to water system.The utility model is simple in structure, Nover practical.
Description of drawings
Figure one is the utility model structural representation
Among the figure, 1-cylinder body, 2-piston, 3-valve, 4-spring, 5-joint.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further, but is not limited to embodiment.
Embodiment 1
As shown in Figure 1; the utility model is made of cylinder body 1, piston 2, valve 3, joint 5; in cylinder body 1, add air pressure by valve 3; make piston 2 shift the position of close port connections 5 onto; joint 5 is connected near the gate valve of water pipe; when closing gate valve; water hammer pressure promotes piston 2 and moves; slowed down the destruction of water hammer to water system; protected water system; when this pressure disappears, because promoting piston 2 again, the compressed-air actuated effect in the piston 2 moves near the joint 5, prepare to slow down the pressure of water hammer next time.
As shown in Figure 1; the utility model is made of cylinder body 1, piston 2, spring 4, joint 5, because the effect of spring 4 promotes the position that piston 2 moves to joint 5; joint 5 is connected near the gate valve of water pipe; when closing gate valve, water hammer pressure promotes piston 2 and moves, and has slowed down the destruction of water hammer to water system; protected water system; when this pressure disappears, because promoting piston 2 again, the effect of the spring in the piston 2 moves near the joint 5, prepare to slow down the pressure of water hammer next time.

Claims (1)

1. a water hammer pressure slows down device, form by cylinder body, piston, valve and spring, it is characterized in that cylinder body one end opening, the other end sealing, inside at the airtight end of cylinder body is placed with spring, one end of cylinder body opening has piston to place in the cylinder body, and an end that seals at cylinder body is externally connected to valve.
