Abstract

PROBLEM TO BE SOLVED: To pump up and discharge liquid even if a pump is in an inclined posture by providing valve bodies placed on valve seats in the valve casings of inlet and outlet sides so as to be vertically moved along guiding projections around the valve casings. SOLUTION: A plurality of guiding projections 17 are provided in the inner periphery of an inlet side valve casing 13 projectingly in upper and lower directions. A spherical valve body 18 is placed on a valve seat 15 in the inlet side valve casing 13, and this valve body 18 is vertically moved by being guided by the plurality of guiding projections 17 between the valve seat 15 and a perforated plate 14. A plurality of guiding projections 17 are provided in the inner periphery of an outlet side valve casing 19 projectingly in upper and lower directions. A spherical valve body 24 is placed on a valve seat 20 in the outlet side valve casing 19, and this valve body 24 is vertically moved by being guided by the plurality of projections 17 between the valve seat 20 and a perforated plate. Thus, while a piston 7 is reciprocated up and down by the operation of a manual handle, the valve bodies 18 and 24 are accurately moved up and down and thus sufficient discharge pressure is provided even in a slope area.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manual pump operated manually.

[0002]

2. Description of the Related Art As conventional small manual pumps, there are blade rotary manual pumps, wing pumps, plunger type pumps and the like.

The vane rotary manual pump is a manual rotary pump used for pumping a small amount of oil or oil from a drum can to a plastic container or a pail can.

This vane rotary type manual pump comprises a pump casing, a rotary vane, a rotary vane shaft, and a rotary handle. When the rotary handle is manually rotated, the rotary vanes inside the pump casing rotate. Since it is a method of pumping up the liquid with a large gap between the pump casing and the rotary vanes, it is not possible to output a high discharge pressure, so it is used for applications that require a certain constant pressure, such as filtration equipment. Can not do it.

The wing pump has a pump casing and
It is composed of a core shaft integrated with the core, two wings attached to both ends of the core portion, and a handle swinging the core shaft.

Although this wing pump has a self-sufficiency capability and is capable of producing a discharge pressure as well, since it is a closed system in which the pump casing and the wing come into contact with each other to produce the pump pressure, the wing pump is separated from the core and the wing. The frictional resistance is large, the operation of the handle is heavy and labor-intensive, and it is difficult for the elderly and children to operate. Further, since the liquid is pumped and discharged by the operation of the wings, the amount of liquid discharged in one swing is small, which requires a considerable amount of labor such as when a large amount of liquid is required. It is difficult to secure the required amount.

The plunger type pump is composed of a cylinder, a piston and a piston rod, an operating handle, and a swing check valve or a ball check valve. The check valve is reciprocated by utilizing the reciprocating motion of the piston. As the pump is operated by opening and closing to perform suction and discharge, the check valve will not operate normally unless the pump is installed on a flat place or in an upright position. Will lose its ability. Similarly, when the check valve is a ball valve, when the pump tilts, the ball that serves as the valve shifts from the center and moves away from the valve seat, losing its function as a valve and causing the pump to stop operating normally. The stop valve becomes open, making it impossible to pump up and discharge the liquid.

[0008]

In the conventional manual pumps, in the event of a disaster such as an earthquake, in a place inclined by the earthquake, in a remote area, in a mountainous area or where there is no power source or power source,
When trying to filter water from rivers and lakes, or pooled water from pools and ponds and use it as daily life water, sufficient discharge pressure cannot be obtained, or the pump cannot be pumped due to inclination. There was a problem that it was heavy and difficult.

The present invention solves such a problem and is capable of pumping a large amount of liquid and discharging the liquid at a sufficient pressure. The pump functions as a pump even when the pump is tilted. It is an object to provide a manual pump that can be easily operated.

The upper part of the container is connected to the sterilizing material container 6, and the nipple 29 of the sterilizing material container 6 can be connected to a hose for liquid supply (not shown).

Next, the operation of the above-mentioned device will be described.

In a city or the like, the trolley 1 shown in FIG. 1 is stored in advance at a place designated as an evacuation site in preparation for a disaster, and the trolley is moved to a remote area, a mountainous area, or another place without a power source or power source. At times, the carriage 1 is carried along with other luggage.

At the time of a disaster such as an earthquake, or in a place inclined due to the earthquake, in a remote area, a mountainous area, or any place where there is no power source or power source, the water of a river or lake, or pool water or pooled water is filtered. Then, when it is going to be used as domestic water, the cart 1 is taken out and installed near a river, a lake, a pool, or the like.

The nipple 27 at the bottom of the filter container 4
Is connected to one end of a suction hose (not shown), and the other end of the suction hose is inserted into water such as a river, a lake, or a pool.

Even if the trolley 1 is installed on a sloping ground and the cylinders 3 and the like are tilted with respect to the vertical line, as shown in FIG.
The spherical valve bodies 18 and 24 shown in FIG.
Since it displaces along the valve seats 7, it does not shift with respect to the positions of the valve seats 15 and 20, and stands still in a state of closely contacting the valve seats 15 and 20 accurately.

In this state, when the manual handle 10 of FIG. 3 is operated in the vertical direction, the piston 7 is moved up and down in the cylinder 3 via the link 9 and the piston rod 8 of FIG.

When the piston 7 rises, the piston 7
Since the lower surface of the valve has a negative pressure, the valve body 18 in the intake side valve casing 13 is guided by the guide ridges 17 and the perforated plate 14
The valve body 24 in the discharge side valve casing 19 is adsorbed on the valve seat 20 and is accurately attached to the valve seat 20. The valve seat 20 is closed while keeping close contact with the valve seat 20.

When the piston 7 descends, the piston 7
Becomes lower than the atmospheric pressure, the valve body 18 in the suction side valve casing 13 is pressed against the valve seat 15, and the valve seat 15 is brought into close contact with the valve seat 15 accurately to close the discharge side valve casing 19. The inner valve body 24 is pushed up from the valve seat 20 and separated from the valve seat 20, and makes the discharge port 23 have a pressure higher than the atmospheric pressure.

By repeating the vertical operation of the manual handle 10, the vertical reciprocating motion of the piston 7 and the opening / closing operation of the valve elements 18 and 24 are repeated, and the manual handle 10 is connected to the nipple 27 at the bottom of the filter container 4. Water from rivers, lakes and marshes, or pools is sucked up from a suction hose (not shown), which is sucked into the cylinder 3 through the filter in the filter container 4, and then discharged from the cylinder 3 into the activated carbon container 5. After passing the activated carbon and the sterilizing material in the sterilizing material container 6, it is supplied as household water from a hose (not shown) connected to the nipple 29 of the sterilizing material container 6.

While the manual handle 10 is repeatedly operated in the vertical direction and the piston 7 reciprocates in the vertical direction, the valve elements 18 and 24 are guided by the plurality of guide ridges 17 and are not displaced laterally. Since the vertical movements are repeated accurately and lightly, the valve seats 15 and 20 can be opened and closed accurately, and sufficient discharge pressure can be obtained with a small amount of labor even when the trolley 1 is installed on a sloping ground. .
