Abstract
A pluggable anti-freezing emptying valve for a solar water heater is mainly composed of a cylindrical nylon plug formed through a die, a sliding pull rod, a sliding silica gel sealing plug and a fixed silica gel sealing plug. According to the working mode of the pluggable anti-freezing emptying valve, the pull rod penetrates through the fixed silica gel sealing plug, the sliding silica gel sealing plug is fixed to the top end of the pull rod and inserted into an air inlet pipeline of the cylindrical nylon plug, the fixed silica gel sealing plug is fixed to the opening in the bottom of the air inlet pipeline of the cylindrical nylon plug, the pull rod is moved upwards to the top dead center, the sliding silica gel sealing plug blocks an air inlet so that a water inlet can be communicated with a drain pipe, and hot water can flow out. The pull rod is moved downwards to the lower dead center, the sliding silica gel sealing plug blocks the water inlet so that the air inlet can be communicated with the drain pipe, and water in the pipe can be drained and emptied. The pluggable anti-freezing emptying valve is especially suitable for users of the solar water heater with a draining outlet arranged in the lower portion. By inserting the pluggable anti-freezing emptying valve into the appropriate draining outlet or an appropriate vacuum tube opening, freezing preventing and emptying of the drain pipe of the solar water heater can be operated freely.
Description
Technical field
The utility model is solar water heater plug type anti-freezing emptying valve, it is formed by the one-time formed cylinder nylon obstruction of mould improvement, be applicable to having the solar water heater user of underlying sewage draining exit, also can pull down a vacuum tube and install and use, realize the antifreeze and emptying of water heater down pipes road winter.
Background technique
Solar water heater is universal to be installed more than 10 year, solve the idle emptier of winter solar energy water heater a lot of especially, built-in emptying just new product in recent years, old user for the solar water heater of having installed, can only install external exhaust-valve additional, solve pipe evacuation in winter, but heat insulating bucket arrives the water outlet Stainless Steel Tube of emptying valve body at extremely cold weather, freezes equally bad use.The emptying mechanism of the utility model, in thermal insulation layer, prevents from winter from freezing, and product is installed simple, and without making house calls of professional workforce, old and new users can use the hot water of solar water heater in the winter time.
Model utility content
Technical problem to be solved in the utility model is: 1,, by sliding tie rod, slidably silica gel sealing plug is moved up or down, shutoff water intake or suction port, solve the difficult problem that old and new users's winter solar energy water heater sewer easily freezes.2, this model utility is directly inserted in solar water heater underlying sewage draining exit, also can be inserted in the mouth of pipe of vacuum tube.
For solving the problems of the technologies described above, the technical solution adopted in the utility model: it comprises the obstruction of cylinder nylon, sliding tie rod, slidably silica gel sealing plug and fixing silica gel sealing plug.It is characterized in that: pull bar is through silica gel sealing plug, silica gel sealing plug is slidably fixed on to the top of pull bar, insert in the suction tude of cylinder nylon obstruction, fixing silica gel sealing plug is fixed on the suction tude bottom mouth of pipe that cylinder nylon stops up, pull bar is moved upwards up to top dead center, slidably silica gel sealing plug shutoff suction port, makes water intake communicate with sewer, and hot water flows out immediately; Pull bar is moved down into lower dead center, slidably the shutoff of silica gel sealing plug water intake, suction port and sewer communicate, and make in pipeline current only emptying.。
Further, described slidably silica gel sealing plug moves up or down by sliding tie rod, shutoff water intake or suction port.
Further, described sliding tie rod moves up or down by manual or electronic realization.
Effect of the present utility model is: solved the solar water heater upper and lower pipeline problem that hot water can not flow down of enduring cold in the winter time: the problem that solves the bad use of old user solar water heater blowdown stopper.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail
Accompanying drawing is structural representation of the present utility model.
Embodiment
Shown in accompanying drawing, working procedure of the present utility model is as follows:
Cylinder nylon stops up the suitable suction tude (9) of the upper prolongation of suction port (8) of (1), then inserts in the sewage draining exit of solar water heater underlying.Sliding tie rod (5) is through fixing silica gel sealing plug (6), slidably silica gel sealing plug (2) is fixed on the top of sliding tie rod (5), slidably, in the pipeline of the suction port (8) of silica gel sealing plug (2) insertion cylinder nylon obstruction (1), the duct bottom mouth of pipe of the suction port (8) of (1) is stopped up in fixing silica gel sealing plug (6) shutoff at cylinder nylon.Suction tude (9) communicates by suction port (8) and pipeline (10) with sewer (4).
During water, sliding tie rod (5) is moved upwards up to top dead center, and slidably silica gel sealing plug (2) shutoff suction port (8), makes water intake (7) communicate with sewer (4), and hot water flows out immediately.When emptying, antifreeze, sliding tie rod (5) is moved down into lower dead center, silica gel sealing plug (2) shutoff water intake (7) slidably, suction port (8) and sewer (4) communicate, make in pipeline current only emptying, guarantee drainage pipeline emptying, antifreeze.
Claims (3)
1. solar water heater plug type anti-freezing emptying valve, comprise the obstruction of cylinder nylon, sliding tie rod, slidably silica gel sealing plug, fixing silica gel sealing plug, its feature: pull bar is through silica gel sealing plug, silica gel sealing plug is slidably fixed on to the top of pull bar, insert in the suction tude of cylinder nylon obstruction, fixing silica gel sealing plug is fixed on the suction tude bottom mouth of pipe that cylinder nylon stops up, pull bar is moved upwards up to top dead center, silica gel sealing plug shutoff suction port slidably, water intake is communicated with sewer, and hot water flows out immediately; Pull bar is moved down into lower dead center, slidably the shutoff of silica gel sealing plug water intake, suction port and sewer communicate, and make in pipeline current only emptying.
2. solar water heater plug type anti-freezing emptying valve according to claim 1, is characterized in that: described slidably silica gel sealing plug moves up or down by sliding tie rod, shutoff water intake or suction port.
3. solar water heater plug type anti-freezing emptying valve according to claim 2, is characterized in that: described sliding tie rod moves up or down by manual or electronic realization.
