Description

Water suppressor

Technical Field

The utility model relates to a but hydrophone technical field, in particular to buoyancy valve.

Background

Valves (Valve) are mechanical devices that control the flow, direction, pressure, temperature, etc. of a flowing fluid medium, and are essential components in piping systems. Valve tubing is technically the same as pumps and is often discussed as a separate category. The valve can be operated manually or by a hand wheel, a handle or a pedal, and can also be controlled to change the pressure, the temperature and the flow of the fluid medium.

The conventional valve used by water conservancy at present is in a closed state in a normal state, basically needs manual intervention operation, and is inconvenient to use.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a water-restraining device to solve the traditional valve that present water conservancy used, all need manual intervention basically, use inconvenient problem.

In order to solve the technical problem, the utility model provides a water inhibitor, which comprises an outer cylinder and an inner cylinder arranged in the outer cylinder, wherein the outer cylinder is a cylinder with an opening at the top end, the top end of the outer cylinder is tightly covered with an upper cover, and the bottom ends of the upper cover and the outer cylinder are respectively provided with a first through hole and a second through hole which are respectively communicated with a vacuum pump and a water inlet pipe; and a plunger is arranged at the top end of the inner barrel and used for blocking the first through hole.

Optionally, the upper cover is a cylindrical barrel with an opening at the bottom end, the outer wall of the bottom end of the upper cover and the outer wall of the top end of the outer barrel are provided with mutually matched clamping blocks, and a clamp is sleeved on the outer side of each clamping block.

Optionally, a guide block is arranged between the inner wall of the outer cylinder and the outer wall of the inner cylinder, and is used for righting the inner cylinder.

Optionally, a sealing gasket is sleeved at the top end of the plunger.

The utility model provides an among the water inhibitor, including the urceolus with arrange in the inner tube of urceolus, wherein, the urceolus is the top open-ended barrel, the top of urceolus closely covers and is equipped with the upper cover, the bottom of upper cover and the urceolus is opened first through-hole and second through-hole respectively, and communicates with vacuum pump and inlet tube respectively; and a plunger is arranged at the top end of the inner barrel and used for blocking the first through hole. Through the combined action of the gravity of the inner barrel, the negative pressure in the outer barrel and the pressure of water in the outer barrel, the automatic control of the water inlet work of the water inlet pipe is realized, manual intervention is not needed, the automation degree is high, manpower is saved, and the working efficiency is improved.

Drawings

Fig. 1 is a schematic structural diagram of a water suppressor according to the present invention.

Detailed Description

The water suppressor according to the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more fully apparent from the following description and appended claims. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.

Example one

The utility model provides a water inhibitor, which comprises an outer barrel 1 and an inner barrel 2 arranged in the outer barrel 1, wherein the outer barrel 1 is a barrel with an opening at the top end, the top end of the outer barrel 1 is tightly covered with an upper cover 10, the upper cover 10 is provided with a first through hole 11 and communicated with a vacuum pump 3, and the bottom end of the outer barrel 1 is respectively provided with a second through hole 12 and communicated with a water inlet pipe 4; the top of inner tube 2 is equipped with plunger 5, the top cover of plunger 5 is equipped with sealed pad 50 for block up first through-hole 11.

Specifically, the upper cover 10 is a cylindrical barrel with an opening at the bottom end, the outer wall of the bottom end of the upper cover 10 and the outer wall of the top end of the outer barrel 1 are provided with clamping blocks 7 which are matched with each other, and a clamping hoop 8 is sleeved on the outer side of each clamping block 7. And a guide block 6 is arranged between the inner wall of the outer barrel 1 and the outer wall of the inner barrel 2 and used for righting the inner barrel 2 to prevent the inner barrel 2 from toppling over in the floating process, so that the plunger 5 and the first through hole 11 are always positioned on the same vertical axis.

When the water suppressor is used, the vacuum pump 3 works to generate negative pressure in the outer cylinder 1, water in the water inlet pipe 4 enters the outer cylinder 1 through the second through hole 12 under the action of the negative pressure, the inner cylinder 2 floats upwards under the action of buoyancy, when the inner cylinder 2 floats upwards to the highest position, the plunger 5 blocks the first through hole 11, and the vacuum pump 3 cannot continue to generate negative pressure in the outer cylinder 1; at this time, the negative pressure in the outer cylinder 1, the gravity of the inner cylinder 2 and the buoyancy thereof are maintained in a balanced state, and the water inlet pipe 4 cannot continuously feed water; when the water quantity in the water inlet pipe 4 is insufficient or the water in the water inlet pipe 4 contains bubbles, the water level in the outer barrel 1 is lowered, the plunger 5 is lowered to open the first through hole 11, the vacuum pump 3 continues to work, so that negative pressure continues to be generated in the outer barrel 1, and the water inlet pipe 4 continues to feed water into the outer barrel 1. Thus, the operation is repeated.

The utility model provides a pair of water inhibitor is when using, through inlet tube 4 and the delivery port intercommunication of water pump make and fill water in the water pump all the time, after the water pump stop work, can not contain the water level decline in gaseous or the pipeline leakage scheduling problem leads to the water pump because of among water or other liquid medium. The water pump is convenient to start again.

The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and any modification and modification made by those skilled in the art according to the above disclosure are all within the scope of the claims.
