Detailed Description
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following description of the present invention is provided with reference to the accompanying drawings, which are only some embodiments of the present invention, and it is obvious for a person skilled in the art to obtain other drawings without creative efforts.
As shown in fig. 1 to fig. 3, the dual-drive drain valve according to an embodiment of the present invention includes a valve body 10 having a drain opening 11, a valve core assembly 20 movably disposed in the valve body 10 up and down, a lifting driving mechanism 30 driving the valve core assembly 20 to move upward to open the drain opening 11, and a pneumatic driving mechanism 40 driving the valve core assembly 20 to move upward to open the drain opening 11. The valve body assembly 20 is provided with a valve plate 21 for opening and closing the drain port 11, and the valve plate 21 is in sealing engagement with or disengaged from the drain port 11.
The lifting driving mechanism 30 drives the valve core assembly 20 to move upwards through a transmission member, specifically a lifting rod 32 described below, that is, the lifting driving mechanism 30 drives the valve core assembly 20 through a mechanical transmission structure.
The pneumatic driving mechanism 40 is driven by gas as a working medium, and drives the valve core assembly 20 to move upwards through air pressure, and the working principle of the pneumatic driving mechanism is well known in the art and will not be described in detail here. In order to realize the two-stage water discharge function, the pneumatic driving mechanism 40 includes a large discharge pneumatic driving mechanism 40a for controlling the water discharge valve to perform a large discharge and a small discharge pneumatic driving mechanism 40b for controlling the water discharge valve to perform a small discharge. In the prior art, there are various ways to realize double discharge of the drain valve, such as a stroke difference way or a counterweight way. When the large-discharge and small-discharge modes are controlled by adopting the stroke difference mode, the stroke for driving the valve core assembly 20 to move upwards when the large-discharge pneumatic driving mechanism 40a is driven is larger than the stroke for driving the valve core assembly 20 to move upwards when the small-discharge pneumatic driving mechanism 40b is driven. When a counterweight mode is adopted, a large-row control mechanism (not shown) and a small-row control mechanism (not shown) which are provided with control floating barrels (not shown) are arranged in the valve body, when the large-row control mechanism is driven, the counterweight structure (not shown) does not play a counterweight role on the control floating barrels, so that the control floating barrels fall down later, and the time for opening the water outlet 11 by the valve core assembly 20 is longer, so that large-row drainage is realized; when the small-row control mechanism is driven, the counterweight structure plays a counterweight role on the control floating barrel, so that the control floating barrel falls earlier, the time for opening the water outlet 11 by the valve core assembly 20 is shorter, and small-row drainage is realized. Thus, when the large-discharge pneumatic driving mechanism 40a is driven, the large-discharge pneumatic driving mechanism 40a drives the large-discharge control mechanism in the valve body 10 to control the drain valve to perform large discharge, and when the small-discharge pneumatic driving mechanism 40b is driven, the small-discharge pneumatic driving mechanism 40b drives the small-discharge control mechanism in the valve body 10 to control the drain valve to perform small discharge.
Specifically, in the present embodiment, the large-discharge pneumatic driving mechanism 40a and the small-discharge pneumatic driving mechanism 40b respectively include pneumatic buttons 41a and 41b capable of outputting gas, air bag modules 42a and 42b, and flexible air tubes 43a and 43b for connecting the pneumatic buttons 41a and 41b and the air bag modules 42a and 42 b. When the pneumatic buttons 41a and 41b are pressed, air is delivered to the corresponding air bag assemblies 42a and 42b through the corresponding flexible air pipes 43a and 43b, the air actuates the movable members 421a and 421b of the air bag assemblies 42a and 42b, and the movable members 421a and 421b are in abutting fit with the step 22 on the valve core assembly 20 to drive the valve core assembly 20 to move upwards. Alternatively, the air bag modules 42a, 42b may be configured as a cylinder module (not shown) which typically includes a cylinder and a piston movable relative to the cylinder to compress the air in the cylinder, with the same effect.
In order to make the structure more compact, the air bag assemblies 42a, 42b of the large-row pneumatic driving mechanism 40a and the small-row pneumatic driving mechanism 40b are symmetrically arranged on the valve body 10, the pneumatic buttons 41a, 41b of the large-row pneumatic driving mechanism 40a and the small-row pneumatic driving mechanism 40b are assembled together, and the installation positions of the pneumatic buttons 41a, 41b can be selected according to requirements.
The lifting driving mechanism 30 is a mechanical structure for driving the valve core assembly 20, and includes a driving panel (not shown), a key (not shown) disposed on the driving panel, a bracket 31, a lifting rod 32 rotatably attached to the bracket 31 and cooperating with the valve core assembly 20, and a longitudinally extending lifting rod 33. The bottom end of the lifting rod 33 is connected with the valve core assembly 20, the top end of the lifting rod 33 is in hanging fit with the lifting rod 32, the key is driven to drive the lifting rod 32 to rotate upwards relative to the support 31, the lifting rod 32 further lifts the lifting rod 33 upwards, the lifting rod 33 further drives the valve core assembly 20 to move upwards, and therefore the water discharge port 11 of the water discharge valve is opened to achieve the water discharge function.
Similarly, in order to realize the double stage drain function, the lifting drive mechanism 30 also includes a large discharge lifting drive mechanism 30a for controlling the drain valve to perform a large discharge and a small discharge lifting drive mechanism 30b for controlling the drain valve to perform a small discharge. Similar to the above pneumatic driving mechanism 40 controlling the drain valve to perform double draining, the stroke for driving the valve core assembly 20 to move upwards when the large-drain lifting driving mechanism 30a is driven can be selected to be larger than the stroke for driving the valve core assembly 20 to move upwards when the small-drain lifting driving mechanism 30b is driven, so as to control double draining of the drain valve through stroke difference; alternatively, a large discharge control mechanism (not shown) and a small discharge control mechanism (not shown) may be provided in the valve body 10, and when the large discharge pulling and driving mechanism 30a is driven, the large discharge pulling and driving mechanism 30a drives the large discharge control mechanism in the valve body 10 to control the large discharge of the water discharge valve 10, and when the small discharge pulling and driving mechanism 30b is driven, the small discharge pulling and driving mechanism 30b drives the small discharge control mechanism in the valve body 10 to control the small discharge of the water discharge valve 10.
In order to make the structure more compact, the driving panels of the large row pulling and driving mechanism 30a and the small row pulling and driving mechanism 30b are integrated, and the brackets 31 of the large row pulling and driving mechanism 30a and the small row pulling and driving mechanism 30b are integrated.
The utility model discloses both having been equipped with mechanical system driven and having carried actuating mechanism, having pneumatic mode driven pneumatic actuating mechanism again, the actuating system can select as required, and the drive is more nimble, and the commonality is better, and the mounted position is nimble, and the function is more reliable.
While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
