Abstract
The utility model relates to a self shutting valve for a complementary vacuum pipe solar water heater. A float of the utility model is connected with a connecting ring positioned at the top part of a guide rod through a guide chain. A stator and a rotor are arranged in a valve body. The guide rod penetrates through the stator and the rotor. The lower end of the guide rod is connected with a counterweight nut. A pressing nut is positioned at the upper part of the stator and is matched with the top part of the valve body through a screw thread. The middle part of the pressing nut is provided with a guide sleeve for preventing the guide rod from moving to be deflected. The valve body is connected with a leading pipe. The leading pipe is led out of a water inlet and a water outlet of a water tank through a leading line to be connected with a joint. The installation of the utility model is simple and convenient. A water level can be controlled. A fault does not easily happen.
Description
The utility model relates to a kind of compensation type solar vacuum-tube water heater self-closing valve, belongs to the technical field of solar water heater servicing unit.
Prior solar water heater all is in the boring of water tank side wall upper part for realizing automatic loading water usually, and a common ball-cock assembly is installed, or add a ball float case at water tank, or the ball-cock assembly external diameter is made identical with the vacuum tube diameter, and be folded down a vacuum tube, refill a ball-cock assembly.Its shortcoming is that outer box ball-cock assembly is installed complicated and the insulation difficulty, and interior box conventional ball-cock assembly is contained in interior upper box part outward, is difficult for heat radiation and water tank to make difficulty, and conventional ball-cock assembly is not closed completely simultaneously, is out of order easily.
The purpose of this utility model provides a kind of compensation type solar vacuum-tube water heater self-closing valve, and it can overcome above-mentioned shortcoming.Self-closing valve is installed in the solar water heater water tank, is drawn and fixing by the water tank intake-outlet, and water is all by this valve up and down.Its structure that needn't change existing ordinary vacuum tube solar water heater simple in structure: add the dress self-closing valve and can satisfy the function that water is closed completely automatically, dependable performance has realized the operation of automation.
The purpose of this utility model is achieved in that float (1) is connected with the connecting ring (3) at guide rod (4) top by leading chain (2), stator (7) and moving plate (8) are housed in the valve body (6), guide rod (4) passes stator (7) and moving plate (8), its lower end has screw thread, fixes a counterweight nut (9); Between this nut (9) and the moving plate (8) rubber blanket (16) is housed, clamp nut (5) is positioned at stator top, and with valve body (6) top with threaded engagement, clamp nut (5) middle part is connected with a guide pin bushing (17), is connected with a fairlead (10) on the valve body (6).Fairlead (10) is outwards drawn from water tank (13) intake-outlet (14) by lead-out wire (15), and is affixed with O-ring seals (12) and joint (11).Fairlead (10) is made with metal or plastics.
Fig. 1. compensation type solar vacuum-tube water heater self-closing valve scheme of installation
Fig. 2. compensation type solar vacuum-tube water heater self-closing valve scheme of installation
Fig. 3. compensation type solar vacuum-tube water heater self-closing valve scheme of installation
Now in conjunction with the accompanying drawings the structure of compensation type solar vacuum-tube water heater self-closing valve is described in detail:
By Fig. 3, float (1) is connected with the connecting ring (3) at guide rod (4) top by leading chain (2), and stator (7) and moving plate (8) are housed in the valve body (6), and guide rod (4) passes stator (7) and moving plate (8), and its lower end has screw thread and is used for fixing a counterweight nut (9); Between this nut (9) and the moving plate (8) rubber blanket (16) is housed, clamp nut (5) is positioned at stator (7) top, and with valve body (6) top with threaded engagement, clamp nut (5) middle part is connected with a guide pin bushing (17), can guarantee that guide rod (4) moves up and down that deflection is not oblique; Float (1) is a cylindric case tube, and float (1) and valve body (6) can be put into by water tank vacuum tube jack, is convenient to change and maintenance.
As shown in Figure 1 and Figure 2, unload a vacuum tube during use earlier near water tank water inlet pipe and water outlet pipe (14), with self-closing valve one section passes the jack that water tank (13) is gone up vacuum tube earlier again, make it all enter water tank (13), then fairlead (10) is outwards drawn from water tank (13) intake-outlet (14) by lead-out wire (15), and fairlead (10) also put in intake-outlet (14), make fairlead (10) by intake-outlet (14), O-ring seals (12) and special joint (11) and tighten special joint.
Before water tank (13) is just gone up water, float (1) is in water tank (13) bottom, guide rod (4), lead chain (2), connecting ring (3) and moving plate (8) and counterweight nut (9) are because gravity effect whereabouts, step by valve body (6) blocks, when beginning to go up water, water enters from fairlead (10), between driven disc (8) and the stator (7) but slit, the through hole of the through hole of stator (7) and clamp nut (5) enters water tank, float this moment (1) is under buoyancy, chain (2) is led in drive, connecting ring (3) and moving plate (8) contact with stator (7) until moving plate (8) with counterweight nut (9) come-up, because moving plate (8) and stator (7) all adopt ceramic material to spread out to be ground and is processed into, so the plane promptly seals once contact, self-closing valve cut out and no longer went up water this moment; Cut off during water intaking and go up the water source, open and use the water source, ducted water counterweight nut (9), guide rod (4), moving plate (8), because the gravity effect is sunk, moving plate (8) separates with stator (7), and the water in the water tank can be taken, and repeats above-mentioned steps when going up the water water intaking again and gets final product.
Compared with prior art, compensation type solar vacuum-tube water heater self-closing valve has following advantages:
1. water tank needn't be holed, and is convenient to install self-closing valve, need not to change the structure of existing solar water heater water tank, Also needn't remove vacuum tube and affect collecting efficiency.
2. fairlead is as water inlet pipe and water outlet pipe, and bile duct is water up and down, does not have the water phenomenon of mixing.
3. the self-closing valve spool adopts ceramic material to make, and through the mill processing of spreading out, sealing property is preferable.
