CN2069492U - Drainage device for liquid - Google Patents

Abstract

The utility model relates to a drainage device for liquid, which comprises a cylinder (11), an upper cover (12), a lower end cover (3) and a piston rod with a handle. The lower end cover is provided with an exhaust one-way valve 5 communicated with the cylinder (11) and a drainage one-way valve (4). The drainage one-way valve is communicated with a tee pipe (6) tightly fixed on one side of the lower end cover. When the utility model is used, the outlet end of the lower end of the tee pipe is sealed and the piston rod is pushed and pulled to and fro, which makes the exhaust one-way valve 5 and the drainage one-way valve respectively opened and closed and air in a drainage tube exhausted. Liquid is drained from one container to another container by an atmospheric pressure. The utility model has the advantages of high drainage degree, convenient operation, small volume and convenient carrying. The utility model is especially suitable for the use of feeding oil into a car by a car driver and also is suitable for the drainage and siphoning of other liquids.

Description

Drainage device for liquid

The utility model is the liquid drainage device of the continuous can of a kind of hydrocone type liquid.

Existing its volume of liquid drainage device is bigger, and lift is not high, uses inconvenience, as disclosed liquid drainage device among the GG86202914, it is by cylinder barrel, piston rod, piston assembly, cylinder cap and draining hole, go out compositions such as head piece, it can only once aspirate, and therefore exists lift not high, shortcomings such as fluid is obstructed need improve its lift during as use, and its cylinder barrel then must extend, then there is the cost height again in piston rods etc., and it is bothersome to take material, volume is big, the not portable and shortcoming used.

The purpose of this utility model just provides a kind of lift height, and volume is little, portable again liquid drainage device easy to use.

The purpose of this utility model realizes by following structure; The liquid drainage device by cylinder barrel and screwed connection on cylinder barrel upper and lower end cap and form by the piston rod of handle; It is characterized in that: in lower end cap, have an exhaust check valve and a drainage one-way valve to communicate with cylinder barrel respectively, at the lower end cap outside fastening one three-way pipe that communicates with the drainage one-way valve.When using the utility model, only need one drainage tube of termination on the three-way pipe, the drainage tube the other end inserts in the interior liquid of container, seal the outlet end of three-way pipe lower end with thumb, make it airtight, upper and lower then reciprocating sliding piston rod, effect by exhaust check valve and drainage one-way valve, air in three-way pipe and the drainage tube that communicates with it thereof can be discharged, make to form negative pressure in the drainage tube, thereby reach the purpose that makes liquid play rainbow or drainage.

In the outlet end of sealing the three-way pipe lower end with thumb, make it airtight for convenience, can make the outlet end end face of three-way pipe become 20-30 degree angle with cylinder barrel.

The utility model has been owing to adopted drainage one-way valve and exhaust check valve, thereby push-and-pull piston rod back and forth, thereby has drainage lift height, and volume is little, and is easy to use, and advantage such as be easy to carry.

Be description of drawings of the present utility model below:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the three-way pipe structure schematic representation;

Among the figure 1, piston rod, 2, sealing gasket, 3, lower end cap, 4, the drainage one-way valve, 5, exhaust check valve, 6, three-way pipe, 7, pressing plate, 8, bowl ring, 9, bridge screw, 10, the piston fixed plate, 11, cylinder barrel, 12, upper end cap, 13, the guiding cushion rubber, 14, handle, 15, drainage tube.

Below in conjunction with drawings and Examples the utility model is further described:

As shown in Figure 1, the utility model is by cylinder barrel 11, piston rod 1, upper and lower end cap 12,3 and piston fixed plate 10, bowl ring 8 compositions such as grade; The exhaust check valve 5 and the drainage one-way valve 4 that communicate with cylinder barrel are arranged in lower end cap, and the drainage one-way valve communicates with the three-way pipe 6 that is fixed in the outside, cylinder barrel lower end.For easy to use and reliable, the end face of three-way pipe lower end outlet end becomes 30 degree angles (as shown in Figure 2) with cylinder barrel, when sealing outlet end (drainage tube 15 inserts in the liquid) with thumb when upwards spurring piston rod, exhaust check valve closes the drainage one-way valve opens, enter in the cylinder barrel with the interior gas of drainage tube in the three-way pipe, when with piston rod when the lower end is moving, the drainage closed check valve, exhaust check valve is opened, discharge the gas in the cylinder barrel, the push-and-pull piston rod then can make liquid in the container play rainbow or by drainage repeatedly, can be under the prerequisite that does not increase its cylinder barrel volume its drainage lift of bigger raising.

Claims (2)

1, a kind of liquid drainage device, by cylinder barrel 11, upper end cap 12, lower end cap 3 and form by the piston rod 1 of handle 14, it is characterized in that: the exhaust check valve 5 and the drainage one-way valve 4 that communicate with the cylinder barrel lower end are arranged on lower end cap, and drainage one-way valve external is fastened on the three-way pipe 6 of lower end cap one side.

2, liquid drainage device as claimed in claim 1 is characterized in that: the outlet end end face of three-way pipe becomes 20-30 degree angle with cylinder barrel.
