Description

Technical Field

[0001] This utility model relates to the technical field of water outlet valves, and in particular to a water outlet valve for outdoor use. Background Technology

[0002] Common outdoor water control valves include faucets, gate valves, and ball valves. After a long period of disuse, the internal valve core of these valves will accumulate scale, increasing friction and making it difficult to open again. In addition, when the temperature drops below zero in winter, the water in the valve will freeze, rendering it unusable. It will need to be thawed before it can be used normally, which is troublesome and inconvenient. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing an outdoor water outlet valve. The switch handle can be easily lifted upwards to drive the piston to open the central water inlet of the bottom valve while simultaneously blocking the drain hole. When the switch handle is closed downwards, the piston blocks the central water inlet while avoiding the drain hole, allowing the remaining water in the outer pipe to drain out through the drain hole. The water outlet valve will not freeze when the temperature is below 0℃, allowing for convenient and normal secondary use.

[0004] To solve the above-mentioned technical problems, the present invention provides an outdoor water outlet valve, comprising: a switch handle, two sets of connecting plates, a connector, a water outlet valve body, a connecting rod, a bottom valve, a piston, and an outer tube. One end of the switch handle has two outwardly protruding positioning bosses on both sides, each with an eccentric circular hole. The upper ends of the two sets of connecting plates have first positioning holes that mate with the positioning bosses and are connected to the top of the water outlet valve body via pins. The two ends of the connector are respectively located below the two sets of connecting plates. The connecting rod is located inside the second positioning hole at the end of the outer tube, and its upper end extends through the top of the outlet valve body and into the central limiting hole of the connector. The connector, connecting piece, and upper end of the connecting rod are fixedly connected by a set screw. The lower end of the connecting rod is threaded with a piston. The upper end of the outer tube is connected to the outlet valve body, and the lower end is connected to the bottom valve. The bottom valve has a central water inlet hole at its lower end and a drain hole on its side. Under normal conditions, the piston at the lower end of the connecting rod blocks the central water inlet hole and avoids the drain hole.

[0005] In a preferred embodiment of the present invention, the top of the water outlet valve body has a connecting lug, and the connecting lug has two sets of mounting holes. The pin passes through the two sets of mounting holes and the eccentric circular hole on the positioning boss to connect the switch handle, the two sets of connecting pieces and the water outlet valve body.

[0006] In a preferred embodiment of the present invention, a plurality of raised ribs are arranged around the inner wall of the bottom valve, and the drain hole is disposed on one of the raised ribs and located above the piston.

[0007] In a preferred embodiment of this utility model, the upper end of the outer tube is threadedly connected to the water outlet valve body, and the lower end of the outer tube is threadedly connected to the bottom valve.

[0008] In a preferred embodiment of this utility model, a sealing ring is fitted on the upper end of the connecting rod, and it is connected to the water outlet valve body by a clamping nut.

[0009] In a preferred embodiment of this utility model, a valve body locking hole is provided on the side opposite to the valve body outlet of the valve body, and a handle locking hole is provided on the other end of the switch handle for use with the valve body locking hole.

[0010] In a preferred embodiment of this utility model, the switch handle has an "L" shaped structure and the inner side has a wavy curve.

[0011] The beneficial effects of this utility model are as follows: The outdoor water outlet valve of this utility model has an eccentric circular hole on the switch handle that is mounted on the water outlet valve body via a pin. Two movable connecting plates are mounted on both sides of the eccentric circular hole on the switch handle. When the switch handle is pulled upward along the pin, according to the lever principle, the power arm is the length of the switch handle and the resistance arm is the radius of the eccentric circular hole. Since the length of the handle is much larger than the radius of the eccentric circular hole, the upward pulling force will be very small. The switch handle can be easily lifted upward to drive the piston to open the central water inlet hole of the bottom valve while blocking the drain hole. When the switch handle is closed downward, the piston blocks the central water inlet hole downward while avoiding the drain hole. The remaining water in the outer pipe is discharged from the drain hole. When the temperature is below 0℃, the water outlet valve will not freeze and can be easily reused normally.

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Please see Figure 1-3 This utility model discloses an outdoor water outlet valve, comprising: a switch handle 1, two sets of connecting plates 2, a connector 3, a water outlet valve body 4, a connecting rod 5, a bottom valve 6, a piston 7, and an outer tube 8. The connecting plates have a first positioning hole 21 and a second positioning hole 22 at both ends. One end of the switch handle has two outwardly protruding positioning bosses 101, with eccentric circular holes 102 on the positioning bosses. The first positioning holes at the upper ends of the two sets of connecting plates can engage with the positioning bosses for a tight fit. The top of the water outlet valve body has connecting ears 41 with two sets of mounting holes 42. A pin 9 passes through the two sets of mounting holes and the eccentric circular holes on the positioning bosses to connect the switch handle, the two sets of connecting plates, and the water outlet valve body. Connected, pulling the switch handle rotates the pin in the eccentric hole to easily lift the piston and open the central water inlet 61. The two ends of the connector are respectively set in the second positioning holes at the lower end of the two sets of connecting plates. The connecting rod is set inside the outer tube and its upper end passes through the top of the water outlet valve body and extends into the central limiting hole of the connector. Then, the set screw 10 abuts against the side rod in the connecting plate to fix the connector, connecting plate and upper end of the connecting rod. The lower end of the connecting rod is threaded to the piston. The upper end of the outer tube is threaded to the water outlet valve body and the lower end is threaded to the bottom valve. The bottom valve has a central water inlet 61 at the lower end and a drain hole 62 on the side of the bottom valve. Under normal conditions, the piston at the lower end of the connecting rod blocks the central water inlet and avoids the drain hole.

[0018] Specifically, the bottom valve has multiple raised ribs 63 arranged around its inner wall. The drain hole is located on one of the raised ribs and above the piston. The outlet valve and the bottom valve are connected by an outer pipe. The bottom valve is buried under the frozen soil layer, while the outlet valve is exposed above the ground. When in use, the switch handle is pulled upward. The rotation of the eccentric hole on the switch handle drives the connecting plate, connector, connecting rod, and piston to move upward together. The piston moves upward along the raised ribs inside the bottom valve, blocking the drain hole. At the same time, the central water inlet of the bottom valve is opened. Water flows through the central water inlet, through the gaps between the raised ribs of the bottom valve, through the outer pipe, and out from the outlet 11 of the outlet valve body. When the handle is closed downward, the piston blocks the central water inlet downward, avoiding the drain hole. At this time, the drain is opened, and the remaining water in the outer pipe is discharged from the drain hole. In working environments with temperatures below 0°C, the outlet valve will not freeze and will not affect its second use.

[0019] Specifically, a sealing ring 12 is fitted on the upper end of the connecting rod and is connected to the outlet valve body through a clamping nut 13, providing good sealing performance.

[0020] Specifically, the switch handle has an "L" shaped structure, which increases the power arm and makes it easy to lift upwards. The inner side has a wave-shaped curve for easy gripping. The valve body has a valve body locking hole 14 on the side opposite to the valve body outlet. The other end of the switch handle has a handle locking hole 15 that works with the valve body locking hole. When not in use, bolts or pins can be passed through the two sets of locking holes to effectively prevent accidental operation.

[0021] The beneficial effects of this utility model are as follows: The eccentric hole on the switch handle is installed on the outlet valve body through a pin. When the switch handle is pulled upward along the pin, according to the lever principle, the power arm is the length of the switch handle and the resistance arm is the radius of the eccentric hole. The length of the handle is much larger than the radius of the eccentric hole, so the upward pulling force will be very small. The switch handle can be easily lifted upward to drive the piston to open the central water inlet of the bottom valve and block the drain hole at the same time. When the switch handle is closed downward, the piston blocks the central water inlet downward and avoids the drain hole. The remaining water in the outer pipe is discharged from the drain hole. When the temperature is below 0℃, the outlet valve will not freeze and can be easily reused normally.

[0022] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
