The utility model is characterized in that the ends of the water falling pipe at least have two valve openings, the number of the corresponding valve covers, soft ropes, and handle rotary arms consistent with that of the valve openings, and a fall gap L between the upper valve opening and the lower opening is maintained; the handle rotary arms can be selected; as the upper valve cover is opened, the quantity of water flowing into the closestool is small; as the lower valve cover is opened, the quantity of water flowing into the closestool is large; thus, persons can save water according to requirements.

Description

Water tank drain valve

The utility model relates to a kind of parts of sanitary installation, particularly relates to a kind of draining valve that is connected with water closet in the water tank.

Conventional be connected with water closet be contained in draining valve in the water tank, include the handle that is installed in the water tank appearance, the valve gap of shutoff leader end valve mouth, be connected in the parts such as soft rope of handle pivoted arm and valve cover chamber.Under the regular situation, turning handle is opened valve gap by soft rope, and the interior water of water tank flows in the water closet towards removing dirt by the valve port of the pipe end that falls into water immediately.When water level was lower than valve port, valve gap is automatic shutoff valve port under action of gravity, and water tank can quantitatively be filled water again.Problem is that valve gap and corresponding valve port are only established a pair ofly in the general draining valve, and valve gap generally all is located at nearly water tank bottom, in case open valve gap, water base stream in the water tank is empty, if people do not need a lot of water to wash away water closet, then flows the very waste that just seems of empty whole box water.

The purpose of this utility model be exactly at the problems referred to above provide a kind of can water-saving water tank drain valve.

The utility model purpose is to realize like this, the promptly main handle of water tank appearance, the water tank drain valve that includes parts such as handle pivoted arm, valve gap, leader, soft rope in the water tank of improving, improvement place promptly is to have only a leader end valve mouth originally, change into and have two corresponding valve gaps at least, the quantity of soft rope, handle and handle pivoted arm is consistent with valve port quantity, and high-order valve port and low level valve port maintain the drop distance of L.People open the valve gap at low level place with handle, and the water yield that flow into water closet this moment is more, and as open the valve gap of high level with another handle, the water yield that flow into water closet this moment is less, has reached the water-saving as required purpose of people.

Utilizing the utility model, is more convenient to the water tank transformation of public offering especially, only need change a leader that two above valve ports are arranged and associated handle device etc.Can obtain water-saving result.

Give to describe in detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation.

Improve a kind of water tank drain valve that is connected with water closet, include handle (1,2) handle pivoted arm (5,6), the valve gap of leader end valve mouth (81), soft rope parts such as (13).A leader has the valve port of at least two pipe ends, and this practicality newly is two (see figure 1)s, according to the volume height of water tank (15), and valve port quantity is unrestricted.Corresponding valve gap, soft rope, handle are consistent with valve port quantity with the handle pivoted arm.The aforementioned part of the utility model also all is two.The water tank appearance is equipped with handle, and at least two handle can be provided with respectively, also can be as the utility model the same axis revolution of can unrolling of each handle, with simplified structure.Be connected with Xiao's axle (21) end as handle (2), Xiao's axle other end is connected with handle pivoted arm (6), and B-B place, soft rope (13) two ends (its material is not limit) is connected with handle pivoted arm (6) other end with valve gap respectively.Cover on the handle (1) can be enclosed within Xiao's axle appearance outward, and long handle pivoted arm (5) is connected with cover.Soft rope (13) ends A-A place is connected with long handle with another valve gap respectively, operates different handles respectively, and promptly the unroll axis of same Xiao's axle of handle turns round, and can open the valve gap at different valve ports place respectively.Cover on the handle (1) is set up copper lining (3) outward again, makes handle rotate flexibly and increase the bearing area of handle.Individual block (4) is arranged, be convenient to the location of handle pivoted arm.Valve gap essence plays the valve effect, can utilize conventional rubber mass leather cup to make valve gap, the utility model valve gap include the renovating (8), be installed in the shutoff pad (10) of renovating soffit of the handle with cover (14) that is connected with soft rope, with renovate the cage (9) that is connected.This kind valve gap structure uses more reliable.In order to increase the shutoff power of valve port,, in leader, there is not magnetic piece (17) near the position of the magnetic piece of corresponding cage equally so the cage end is equipped with the magnetic piece.Play the valve body effect with the leader essence in the water tank that water closet is connected, generally can wholely making, is manufacturing and easy for installation, leader is divided into valve body (11) and breeches pipe (12) two parts of being with valve port, an elbow (16) is extended in the valve body outside, in order to fixedly to renovate handle (14).The valve port that is in the relative low level valve body of valve port of high-order valve body maintains the drop distance of L, and L can calculate according to the displacement of water tank and determine.The lower end of breeches pipe utilizes sealing ring (18), valve rubber (19), big nut (20) to tighten up with water tank bottom.Be the simplified structure water tank, overflow pipe (7) is connected with the elbow ends of high-order valve body.

Claims (4)

1, a kind of water tank drain valve, comprise the handle that is installed in water tank (15) appearance, the interior leader of water tank that is connected with water closet, the valve gap of leader end valve mouth, the soft rope that connects handle pivoted arm and valve cover chamber, the quantity that it is characterized in that leader end valve mouth is at least two, corresponding valve gap, the quantity of soft rope, handle and handle pivoted arm is consistent with valve port quantity, maintains the drop distance of L between high-order valve port and low level valve port.

2, by the described water tank drain valve of claim 1, it is characterized in that each handle has same axis of rotation.

3, by the described water tank drain valve of claim 1, it is characterized in that valve gap include the renovating (8), be installed in the shutoff pad (10) of renovating soffit of the handle with cover (14) that is connected with soft rope (13), with renovate the cage (9) that is connected.
