Description

A new type of antifreeze nozzle

technical field

The invention belongs to the technical field of plumbing pipe fittings, relates to a faucet, in particular to a novel antifreeze faucet.

Background technique

Tap water is closely related with people's daily life, and the use of tap water has brought great convenience to people, and faucet is a kind of device that tap water is realized opening, closing and control outlet water flow. The valve cores of the faucets currently on the market are all installed on the main body close to the water outlet, and the outdoor temperature in winter in the north is very low, and the tap water in rural areas is controlled by the water company for regular water supply, that is, during the time when the temperature is high at noon during the day Water supply, cut off when the temperature is low at night. Once there is residual water in the faucet, it will be frozen at night. In order to prevent tap water from remaining in the pipe faucet, you need to manually open the faucet to deflate after the water is cut off. If you forget to open the faucet to deflate, it will cause the faucet and the pipeline to freeze to death, unable to discharge water, or even freeze and crack.

Contents of the invention

The object of the present invention is to solve the above-mentioned problems in the prior art, and provide a new type antifreeze faucet with simple structure, long service life and no water in the faucet.

The purpose of the present invention can be achieved through the following technical solutions: a new type of antifreeze faucet, including a faucet body and a handle, and a water inlet and a water outlet located at both ends of the faucet body. The water outlet and the water outlet are connected to the flow channel cavity. The outer wall of the water nozzle body close to the water inlet is provided with an integral mounting seat and a threaded joint. It is characterized in that the water nozzle body is provided with a handle Drive the rotating shaft, the upper end of the rotating shaft is connected with the handle, the lower end extends into the flow channel cavity, and the end of the rotating shaft is fixedly connected with an eccentric wheel arranged eccentrically, and the eccentric wheel drives the eccentric wheel in the channel cavity. The valve stem that moves laterally, the spaced partition and the sealing seat are arranged in the flow channel cavity, and the spring is arranged between the partition and the sealing seat, and the spring is sleeved on the valve stem. The top end of the valve stem passes through the partition and contacts the eccentric wheel, the end of the valve stem passes through the sealing seat and is provided with two limit rings integrated with it, and there is a seal between the two limit rings that is sealed with the seal seat. Fitted silicone seals.

The working principle of this new type of antifreeze water nozzle is: the eccentric wheel on the rotating shaft is touched by the control handle to form a cam-like rotation track, and the valve stem equipped with the spring is stretched horizontally. When the sealing seat moves outward, the water flow will enter the flow channel cavity through the sealing seat and then flow out from the water outlet to realize the water discharge function; The seat is sealed and matched to realize the function of shutting off the water, which completely blocks the flow of water from entering the flow channel cavity, and the remaining water in the flow channel cavity will flow out of the water outlet with the slightly inclined flow channel wall, so that there is no water in the flow channel cavity, so the water The phenomenon of being frozen will not appear in the flow channel cavity of the mouth body.

In the above-mentioned novel antifreeze faucet, a trumpet-shaped sealing port is opened in the middle of the sealing seat, and the silicone sealing ring is in contact with the sealing port, and the diameter of the outer ring of the silicone sealing ring is larger than that of the trumpet-shaped sealing port. minimum diameter.

In the above-mentioned novel anti-freezing faucet, the valve stem is sleeved with a washer against which the spring can lean, and the washer is fixedly connected to the valve stem through a clip spring.

In the above novel antifreeze faucet, a sealing ring is provided between the upper end of the rotating shaft and the main body of the faucet.

In the above novel antifreeze nozzle, the sealing seat is located at the threaded joint.

Compared with the prior art, the new antifreeze faucet has the following advantages:

1. The valve stem assembly composed of valve stem, spring, and silicone seal ring cooperates with the bell-shaped sealing port to replace the traditional ball valve structure, so that the water flow is blocked to the outside of the flow channel cavity, so that there is no residual water in the flow channel cavity. , so not only is the structure simple, but also there is no need to wrap the water pipe when the cold season comes, and there will be no freezing phenomenon inside the faucet, which is as smooth as summer, and the service life is greatly extended;

2. When the faucet is closed, the flow channel cavity is not under pressure, so the wall thickness of the faucet body can be made thinner than the traditional faucet, leaving a large design for the structural shape of the faucet body Space, not only beautiful but also greatly save the cost.
