Description

Technical Field

[0001] The invention relates to the field of antifreeze faucets, and in particular to a valve body structure. Background Art

[0002] The antifreeze faucet is a faucet used in relatively cold outdoor environments, mainly comprising a faucet body 100, a pipe body 101, a water inlet pipe 102 pre-buried in the bottom soil layer and affected by the temperature, and a valve body 103 arranged at the lower end of the pipe body 101 to control the inlet and outlet of water.

[0003] When this type of antifreeze faucet is in use, water can flow out of the faucet by opening the valve body controlled by the handle on the faucet body. However, when it is closed, some water will remain in the tube body 101. In order not to affect the normal use of the antifreeze faucet, this part of water needs to be disposed of.

[0004] The existing treatment method is to set a water outlet on the upper side of the valve body, and when the valve body is closed, the water in the pipe body is discharged from the pipe body through the water outlet and discharged into the bottom soil layer. However, the drainage speed in the pipe body is closely related to the permeability of water in the bottom soil layer. When the drainage speed in the pipe body is slow and the environment outside the pipe body is relatively cold, the water in the pipe body will freeze and freeze, thereby affecting the normal use of the pipe body, and even blocking the pipe body and affecting water discharge.

[0005] Although this method can solve the problem of water in the pipe, each time the antifreeze faucet is used, some water will be discharged into the bottom soil layer without being used, resulting in a waste of water resources and affecting the soil quality of the bottom soil layer. Summary of the invention

[0006] The object of the present invention is to provide a valve body structure which has the advantage of being able to reuse the water in the pipe body when the antifreeze faucet is closed.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions:

[0008] A waterproof faucet valve body structure, comprising a valve stem and a valve core arranged on the valve stem head, the lower end of the tube body is connected to the water inlet pipe through the valve body; the valve body comprises a water inlet chamber and a water storage chamber; the lower end of the water inlet chamber is connected to the water inlet pipe through the water inlet, and the upper end is connected to the tube body through the water outlet; the valve stem is arranged in the water storage chamber, the valve core is arranged in the water inlet chamber, and the valve core is driven to block the water inlet through the up and down displacement of the valve stem; the water storage chamber is respectively provided with a first through hole connected to the tube body and a second through hole connected to the water inlet chamber; the second through hole is arranged beside the water inlet, and when the valve core blocks the water inlet, the second through hole is also blocked at the same time; an outlet control component is arranged above the water outlet, which can rotate around the valve stem to close the water outlet through the linkage valve stem displacement; the outlet control component can open the first through hole while closing the water outlet; the water storage chamber is also provided with an extrusion mechanism that uses a piston mechanism to squeeze the water in the water storage chamber through the linkage valve stem displacement, so that it enters the water inlet chamber through the second through hole.

[0009] By adopting the above technical scheme, when the antifreeze faucet is closed, the water in the pipe body above the ground surface can be recovered into the water storage chamber, and when the antifreeze faucet is used next time, the water in the water storage chamber is squeezed into the water inlet chamber by the squeezing mechanism, and the water is discharged through the antifreeze faucet by the water pressure given by the water inlet pipe. Since the water in the pipe body is unused water, the utilization rate of water resources is improved by reusing the water in the pipe body. At the same time, the water in the pipe body will not be discharged into the subsoil layer, and the soil quality of the subsoil layer will not be affected by long-term use. By discharging the water into the water storage chamber in the valve body and no longer discharging it to the subsoil layer outside the valve body, the drainage speed of the pipe body is no longer affected by the permeability of the subsoil layer, so that the water in the pipe body can leave the pipe body quickly. However, freezing of the water body affects the normal use of the antifreeze faucet.

[0010] Further configuration: the outlet control assembly includes a limit rod fixedly arranged on the circumference of the valve stem and a rotating disk sleeved on the valve stem and capable of rotating around the valve stem; an arc-shaped sliding groove cooperating with the movement of the limit rod is arranged at the connection between the rotating disk and the valve stem.

[0011] By adopting the above technical solution, the displacement of the valve stem in the vertical direction is utilized to drive the displacement of the limit rod, and the rotation is realized under the cooperation of the slide slot and the limit rod. The displacement of the valve stem is used as a power source. When the antifreeze faucet is opened, the valve stem moves up, and the rotating disk rotates, thereby opening the water outlet and closing the first through hole of the water storage chamber, so that the water in the water inlet pipe is unidirectionally transported to the pipe body through the valve body. When the antifreeze faucet is closed, the valve stem moves down, so that the rotating disk is reset, and then the water outlet is closed, and the first through hole of the water storage chamber is opened, so that the water in the pipe body enters the water storage chamber through the first through hole. The reflux of water in the pipe body is realized.

[0012] It is further arranged that the extrusion mechanism comprises an extrusion plate which is slidably connected in the water storage chamber and can slide in the vertical direction under force, and a connecting component which links the displacement of the valve stem so that the extrusion plate squeezes downward when the valve stem moves upward.

[0013] By adopting the above technical solution, the displacement of the valve stem is used as a power source to make the squeezing plate squeeze the water in the water storage chamber. When the valve stem moves upward, the second through hole is opened, so that the water in the water storage chamber enters the water inlet chamber under the action of the squeezing plate and leaves the valve body along with the water in the water inlet chamber, thereby realizing the reuse of water resources in the water storage chamber.

[0014] Further arrangement: the connecting assembly includes a sliding base slidably connected to the top of the water storage chamber and can slide in the horizontal direction, a first connecting rod connecting the extrusion plate and the sliding base, and a second connecting rod connecting the valve stem and the sliding base; one end of the first connecting rod is rotatably connected to the extrusion plate, and the other end is rotatably connected to the sliding base; one end of the second connecting rod is rotatably connected to the valve stem, and the other end is rotatably connected to the sliding base.

[0015] By adopting the above technical solution, the displacement of the valve stem is amplified through the connection relationship between the first connecting rod, the second connecting rod and the sliding base, so that when the valve stem moves upward, the extrusion plate presses down a greater distance, which can more fully squeeze the water in the water storage chamber and allow more water to enter the water inlet chamber.

[0016] Further configuration: the shape of the extrusion plate is consistent with the cross-sectional volume shape of the water storage chamber, and a one-way valve is provided on the extrusion plate to allow water to pass through the extrusion plate in one direction from top to bottom; when the extrusion plate moves to the bottom, the second through hole is blocked.

[0017] By adopting the above technical solution, the shape of the extrusion plate is adapted to the water storage chamber, so that the extrusion plate can fully squeeze the water in the water storage chamber. At the same time, a one-way valve is arranged on the extrusion plate, so that the water entering the water storage chamber can pass through the one-way valve and enter under the extrusion plate, so that the extrusion plate can better squeeze the water in the water storage chamber.

[0018] Further configuration: the rotating disk adopts a fan-shaped structure; the first through hole is arranged on one side of the water outlet, and the water outlet is arranged in a strip shape; a sealing gasket is arranged on the contact surface between the bottom of the rotating disk and the valve body.

[0019] By adopting the above technical solution, a fan-shaped structure is used to reduce the contact area between the rotating disk and the valve body, thereby reducing friction, making the rotating disk easier to rotate. At the same time, a sealing gasket is arranged at the bottom of the rotating disk, so that the rotating disk has a better sealing effect when closing the water outlet or the first through hole.

[0020] Further configuration: a pulley which is slidably connected to the arc-shaped sliding groove is sleeved on the limiting rod.

[0021] By adopting the above technical solution, the limiting rod is rollingly connected with the arc-shaped sliding groove through the pulley sleeved on the limiting rod, which makes the rotation of the rotating disk more convenient.

[0022] Further configuration: a movable plate is detachably provided on one side of the water storage chamber of the valve body; the movable plate can be removed, and a water tank for increasing the volume of the water storage chamber can be installed on one side of the valve body; an expansion device adapted to the cross-sectional shape of the water tank can also be installed on one side of the extrusion plate.

[0023] By adopting the above technical solution, the volume of the water storage cavity is increased by removing the movable plate and installing the water storage tank, so that the water in the pipe body can enter the water storage cavity. At the same time, water storage tanks of different capacities can be equipped according to different pipe body lengths to meet the reflux of water in the pipe body.

[0024] It is further arranged that the water tank opening faces the water storage cavity and is detachably connected to the valve body by fastening bolts.

[0025] By adopting the above technical solution, the detachable connection between the water tank and the valve body is achieved by fastening bolts. BRIEF DESCRIPTION OF THE DRAWINGS
