Abstract
The utility model relates to a water heating system which is a heat meter anti-blocking protection device in order to protect the heat meter from not being jammed or locked by the sundries in the water. The utility model utilizes ball type valve core of ball valve, a sewage discharge backflushing hole which is communicated with a valve core perforation is drilled on the back, the opening of the perforation at water inlet side of the valve core is provided with an internally-protruded semi-spherical filter net, when the filter net is jammed by the sundries, an operation handle only needs to be rotated anti-clockwise at 90 degree, the filter net is aligned with one side of the sewage discharge opening of the valve body, the sewage discharge backflushing hole is aligned with one water-coming side, by utilizing the backflushing principle of pressurized water, the sundries on the filter net is drained into hot network system water return tube from the sewage discharge opening, and then the operation handle is reset to normal operation state.
Description
The utility model relates in the heat supply water heating system, for the protection calorimeter is not stopped up or stuck a kind of device by foreign material in the water.
In heating system,, calorimeter all is housed at each family for the heat and the water yield that provides to the user is provided.Through the use of certain hour, pipe interior gets rusty and ties stain, makes the water quality variation.The area that has is in order to reduce heat cost, industrial waste water after handling is used as recirculated water, hot water is usurped in order to prevent the user in the area that also has, in heat supply network, add ight soil and raw sewerage artificially, to supply the water yield in the heat supply network, cause flow sensor in the calorimeter etc. malfunctioning, even make that calorimeter is whole to be scrapped because of the stifled card of impurity, reduction of service life, caused economic loss to the user.For addressing this problem, the method that adopts is in calorimeter inflow direction one side a filtrator to be installed in advance at present, after filtrator is blocked by impurity, have to stop the hot water operation, the artificial unloading changes filtrator, both time-consuming, take material again, in addition in the heat supply network temperature of water up to 80 ℃～90 ℃, so exist very big potential safety hazard.
The utility model purpose is that a kind of improved calorimeter anti-blocking-up protection apparatus will be provided, and under the situation that does not stop the heating system operation, can get rid of foreign material rapidly; need not to change parts, both safety was free from environmental pollution again; make calorimeter obtain protection, and prolonged serviceable life.
The utility model purpose is achieved in that the ball type spool that utilizes in the ball valve, bore a blowdown recoil hole that communicates with the spool passing hole in addition at its back side, on the passing hole aperture of ball type spool influent side, an inwardly protruded semisphere filter screen is set again.When foreign material stop up filter screen, only need operating grip is turned clockwise 90 °, filter screen is aimed at sewage draining exit one side on the valve body, water side's one side is aimed in blowdown recoil hole, utilize the backsurging principle of press water, impurity on the filter screen is entered the heat network system return pipe from sewage draining exit, then operating grip is reset to normal operating condition.
The utility model is because only need bore a blowdown recoil hole that directly communicates with passing hole on former ball type spool, and an inwardly protruded semisphere filter screen is installed on the passing hole aperture, so structure is simple especially, both played filtration, played the effect of removing filter screen impurity at any time again, need not out of servicely, the dismounting filter screen saves time, saving of labor, laborsaving.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is that master of the present utility model looks longitudinal diagram.
Fig. 2 is A-A sectional view of Fig. 1.
Among the figure: 1, ball valve body 2, ball type spool 3, semisphere filter screen 4, handle drive link
5, operating grip 6, temperature sensor jack 7, valve body sewage draining exit 8, blowdown recoil hole
9, flow to
With reference to Fig. 1, Fig. 2, bore a blowdown recoil hole (8) at the back side of ball type spool (2), this hole directly communicates with ball type spool passing hole.Bore a temperature sensor jack (6) again in the bottom surface of ball type spool (2), this hole also directly communicates with ball type spool passing hole.In addition, on the passing hole aperture of ball type spool water inlet direction one side, an inwardly protruded semisphere filter screen (3) is set.In Fig. 1, Fig. 2, the utility model is in normal operation position, and at this moment, hot water enters ball valve along the direction of arrow (9) from right-hand member, through semisphere filter screen (3), goes out from left end.Its water temperature can be passed to calorimeter (not drawing among the figure) by the sensor that inserts temperature sensor jack (6).When semisphere filter screen (3) is blocked, room temperature obviously reduces, the user is as long as turn clockwise 90 ° with the operating grip on the ball valve (5), at this moment, the just synchronous half-twist of ball type spool (2), just make semisphere filter screen (3) aim at the sewage draining exit (7) that is provided with in advance on valve body, water inlet of hot water is also aimed in blowdown recoil hole (8) just, and hot water enters blowdown recoil hole (8) and this device immediately.At this moment, clockwise 90 ° ball type spool is sealed water delivering orifice, so, enter hot water that this device has certain pressure directly pours the foreign material on the filter screen heat network system from sewage draining exit (7) water return pipeline.Wait, again operating grip is reset to normal run location.If temperature sensor damages, as long as handle (5) is rotated counterclockwise 90 °, make the sphere of spool (2) aim at inflow direction (9), then this device is in cut-off state, just can change the sensor in the temperature sensor jack (6) rapidly at short notice.
Claims (2)
1, a kind of calorimeter anti-blocking-up protection apparatus; this device has a ball valve body (1); ball type spool (2); operating grip (5) and handle drive link (4) are arranged on valve body top; it is characterized in that the ball type spool back side is drilled with blowdown recoil hole (8); its bottom surface is drilled with temperature sensor jack (6); and blowdown recoil hole (8) and temperature sensor jack (6) directly communicate with the passing hole of spool (2); on spool (2) right side promptly intakes the passing hole aperture of direction one side, be provided with inwardly protruded semisphere filter screen (3).
2, device according to claim 1 is characterized in that being provided with sewage draining exit (7) in the front of valve body (1).
