Abstract

The utility model discloses a water level control valve for a solar water tank, which comprises a valve seat (1), a float (2), a connecting rod (3), and a valve core (4). The float (2) is located on the upper part of the valve seat (1). The connecting rod (3) is fixedly connected with the valve core (4), and the valve core (4) is located at the lower part of the valve seat (1). There is a stop bar (6) at the middle and lower part. In the utility model, the float (2) is placed in the water tank, and the float (2) and the valve core (4) float up under the action of buoyancy when water is supplied, and the pipeline is blocked to stop water supply and control the water level. When in use, the spool (4) loses buoyancy and sinks, the pipeline is opened, and the water in the water tank is fully utilized.

Description

Solar Water Tank Water Level Control Valve

本实用新型涉及一种水位的控制阀，具体地系一种太阳能水箱水位控制阀。The utility model relates to a water level control valve, in particular to a solar water tank water level control valve.

目前，太阳能热水器已走进了千家万户，成为利用太阳能为人类服务较为普遍的一种产品，深受广大用户喜爱。然而太阳能水箱由于处于房屋顶上或其它较高位置处，给上水带来不便，经常造成由于水箱水位超高溢水现象。既浪费了水也影响了环境。At present, solar water heaters have entered thousands of households and become a relatively common product that uses solar energy to serve human beings, and is deeply loved by users. Yet solar water tank is owing to being on the roof of a house or other higher positions, brings inconvenience to water supply, often causes because the water tank water level superhigh water overflow phenomenon. Not only wasting water but also affecting the environment.

本实用新型之目的，在于提供一种太阳能水箱水位控制装置，使太阳能水箱水位到达预定高度即停止上水，避免了水位超高溢水现象的发生。The purpose of this utility model is to provide a solar water tank water level control device, so that the water level of the solar water tank will stop when the water level reaches a predetermined height, so as to avoid the occurrence of super high water level overflow.

为达到上述之目的，本实用新型采取的技术方案是：本实用新型包括：阀座、浮子、连杆、阀芯，浮子位于阀座上部，通过连杆与阀芯固定相联，阀芯位于阀座的下部，阀座内壁中部有环形挡筋，连杆中下部有挡杆，控制浮子与阀芯的活动范围。In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: the utility model includes: a valve seat, a float, a connecting rod, and a valve core. The lower part of the valve seat, the middle part of the inner wall of the valve seat has an annular retaining rib, and the middle and lower part of the connecting rod has a retaining rod to control the range of motion of the float and the valve core.

本实用新型采取上述之结构，具有以下有益效果：将本实用新型的浮子先通过水箱进出水口插入水箱内，使阀座与水箱进出水口联接一起，阀座下端联接进水管和排水管。上水时，关闭排水管节门，打开进水管节门，水通过阀座进入水箱内，水箱内水位不断上涨，浮子与阀芯在浮力作用下上移，到达一定位置，阀芯与阀座内壁的挡筋接触，封闭管路，上水停止，水位固定。使用水时，关闭进水管节门，打开排水管节门，排水管中的水流出，使阀芯失去水的浮力，浮子与阀芯在重力作用下下落，开通水路，太阳能水箱中的水流出使用。The utility model adopts the above-mentioned structure, which has the following beneficial effects: the float of the utility model is first inserted into the water tank through the water inlet and outlet of the water tank, so that the valve seat is connected with the water inlet and outlet of the water tank, and the lower end of the valve seat is connected with the water inlet pipe and the drain pipe. When filling water, close the joint door of the drain pipe and open the joint door of the water inlet pipe. The water enters the water tank through the valve seat. The water level in the water tank continues to rise. The retaining ribs on the inner wall contact, the pipeline is closed, the water supply stops, and the water level is fixed. When using water, close the joint door of the water inlet pipe, open the joint door of the drain pipe, the water in the drain pipe will flow out, the valve core will lose the buoyancy of the water, the float and the valve core will fall under the action of gravity, the waterway will be opened, and the water in the solar water tank will flow out use.

下面结合附图对本实用新型做进一步详细介绍：Below in conjunction with accompanying drawing, the utility model is described in further detail:

图1为本实用新型结构简图。Fig. 1 is a schematic diagram of the structure of the utility model.

由图1可以看出：本实用新型包括：阀座1、浮子2、连杆3、阀芯4，阀座1为管状体，内壁中部有凸起的环形挡筋5，浮子2位于阀座1上部，其下端通过连杆3固定联接阀芯4，阀芯4能与环形挡筋5接触密封管道。连杆3中下部有与之垂直的挡杆6，挡杆6下落时与环形挡筋5接触，使浮子2与阀芯4停止下落。It can be seen from Fig. 1 that the utility model includes: valve seat 1, float 2, connecting rod 3, valve core 4, valve seat 1 is a tubular body, and there is a raised ring rib 5 in the middle of the inner wall, and float 2 is located on the valve seat. 1. The upper part, the lower end of which is fixedly connected to the spool 4 through the connecting rod 3, and the spool 4 can contact the ring rib 5 to seal the pipeline. The lower part of the connecting rod 3 has a stop bar 6 perpendicular to it, and the stop bar 6 contacts with the annular rib 5 when it falls, so that the float 2 and the spool 4 stop falling.

本实用新型浮子2与阀芯4的选材与体积比较关键，但是都要遵守一个原则：浮子2与阀芯4在水的浮力作用下能上浮；而阀芯4失去水的浮力时浮子2与阀芯4会下沉。The material selection and volume of the float 2 and the spool 4 of the utility model are more critical, but one principle must be followed: the float 2 and the spool 4 can float under the buoyancy of water; Spool 4 will sink.
