Description

A foot-operated valve with controllable water volume

technical field

A foot-operated valve with controllable water volume relates to a foot-operated valve, in particular to a foot-operated valve capable of adjusting the amount of passing water.

Background technique

Most of the existing valves are manual valves, which need to be manually operated during the water use process. When the user is inconvenient to use his hands, it often brings some unnecessary troubles. Among the existing foot-operated valves, there are relatively few foot-operated valves, and the use of foot-operated valves avoids some unnecessary troubles caused by manual operation in the process of watering. However, the foot-operated valves in the prior art, When the user uses it, the amount of water passing through cannot be adjusted, which easily causes water waste.

In order to solve the problem that the foot-operated valve in the prior art cannot control the amount of passing water, the utility model provides a foot-operated valve with controllable water amount which is easy to use and can control the amount of passing water.

The utility model relates to a foot-operated valve with controllable water quantity, which comprises a foot pedal and a valve cavity, and a water flow control plate, a rotating gear and a return spring are arranged in the valve cavity. A water pipe with an opening passes through the valve chamber, and there is a protrusion on the upper part of the water flow control plate. The protrusion extends into the water pipe through the opening on the water pipe, and the protrusion plays a role in blocking the water pipe. The change of the length extending into the water pipe can adjust the minimum cross-sectional area through which the water flow in the water pipe passes. The lower end of the water flow control board is equipped with a return spring, and when the user does not step on the pedal, the return spring lifts the water flow control board, and the above-mentioned protrusions block the water pipe to seal the water pipe. The water flow control plate has gear teeth, and the gear teeth are meshed with the rotating gear. The rotating gear can move the gear teeth on the water flow control plate, and then drive the water flow control plate to move up and down to regulate the water flow. The role of the raised position on the control panel. The pedal is outside the valve cavity, the pedal extends into the valve cavity through a connecting rod, and the rotating gear is connected with the connecting rod. The user steps on the pedal to rotate the pedal, and drives the rotating gear to rotate through the connecting rod, which indirectly moves the water flow control plate downward, and the protrusion on the water flow control plate is pulled out from the water pipe, so the water pipe is no longer blocked. The water can flow out.

Preferably, there is a cylindrical protrusion on the side of the pedal away from the connecting rod, the cylindrical protrusion is on the same axis as the connecting rod, and there is a bracket with a round hole on the side of the cylindrical protrusion. Shaped protrusion stretches in the circular hole of support, and described pedal is hinged with support through cylindrical protrusion. Both sides of the foot pedal are respectively connected to the bracket and the valve cavity, so that the user can step on the foot pedal conveniently, which is more convenient to use.

Preferably, the water flow control plate has 2 to 5 gear teeth. By stepping on the pedal, the water flow control plate is indirectly moved downward for a certain distance, and the protrusion on the water flow control plate is drawn out from the water pipe, so that the water pipe is no longer blocked, and the water flow can flow out.

Preferably, the rotation gear has teeth on 1/3 to 1/2 of its circumference. The toothed portion of the rotating gear occupies 1/3 to 1/2 of the entire circumference, and the pedal only needs to rotate 1/3 to 1/2 of the circumference, which is more convenient for the user to operate the valve.

Compared with the prior art, the utility model has the following beneficial effects:

The water flow control plate of the utility model has gear teeth, and the user drives the rotating gear to rotate by stepping on the pedal, and the rotating gear drives the water flow control plate to move downward. The water flow control plate moves downward for a distance of a gear tooth, and the user has an obvious feeling of being lost when stepping on the pedal. The user can move the water flow control plate downward for a certain distance by stepping on the pedal with different strengths, so as to control the flow of water. purpose of velocity.

Detailed ways

Below in conjunction with Fig. 1 to Fig. 3, the utility model is described in detail.

As shown in Figures 1 to 3, a foot-operated valve with controllable water volume includes a foot pedal 4, a valve cavity 1, and a water flow control plate 5, a rotating gear 7, and a return spring 6 are arranged in the valve cavity 1. A water pipe 2 with an opening passes through the valve chamber 1, and a protrusion 51 is provided on the upper part of the water flow control plate 5, and the protrusion 51 extends into the water pipe 2 through the opening on the water pipe 2, and the protrusion 51 protrudes To block the water pipe 2, the minimum cross-sectional area of the water flow in the water pipe 2 can be adjusted according to the length change of the projection 51 extending into the water pipe 2. The lower end of the water flow control board 5 is equipped with a return spring 6. When the user does not step on the pedal 4, the return spring 6 lifts the water flow control board 5, and the protrusion 51 blocks the water pipe 2, so that the water pipe 2 closed. The water flow control plate 5 has gear teeth 52, the gear teeth 52 are meshed with the rotating gear 7, and the rotating gear 7 can move the gear teeth on the water flow control plate 5, and then drive the water flow control plate 5 Moving up and down plays the role of adjusting the position of the projection 51 on the water flow control plate 5 . The pedal 4 is outside the valve cavity 1, and the pedal 4 extends into the valve cavity 1 through the connecting rod 3; the rotating gear 7 is connected with the connecting rod 3, and the user steps on the pedal 4, Make the pedal 4 rotate, and drive the rotating gear 7 to rotate through the connecting rod 3, indirectly make the water flow control plate 5 move downward, the protrusion 51 on the water flow control plate 5 is drawn out from the water pipe 2, and the water pipe 2 is no longer blocked. The water can flow out.
