Abstract
The utility model relates to a hydraulic self-sealed washing valve, belonging to sanitary ware matching device. The inside of the water inlet of a valve body is provided with a water intake gate; the upper part of the water intake gate is provided with a plug; the middle part of the plug is fixedly connected with a plug rod which can drill through a valve chamber; the lower part of the valve chamber is a rectangular chamber; the plug rod can drill through a plug rod slide way arranged at the middle part of the upper surface of the rectangular chamber so as to enter the rectangular chamber; a push rod in a treadle device can drill through a push rod slide way arranged at the middle part of the bottom surface of the rectangular chamber so as to enter the rectangular chamber; the push rod is corresponding to the plug rod; the periphery of the push rod is sheathed with an elastic sealing bowl whose size is equal to the length of the rectangular chamber. The utility model can cancel the mode that the elasticity of a spring can be used to realize the shutoff operation and the cutoff operation; the utility model adopts the hydraulic self-sealed cutoff mode; therefore, the utility model has the advantages of no pressure loss, long service life, handy opening, etc.
Description
The utility model relates to the flushing valve of a kind of water pressure self-closing formula, is mainly used in flushing toilet closet groove, belongs to the sanitaryware corollary apparatus.
At present, pedals type valve has the sanitary equipment market of some with advantages such as simple, with low cost, convenient and swift, the foot-operated health of its installation, but because the unlatching of foot valve is to utilize spring pressure, and the frequent use of spring constantly reduces its mechanical performance, spring corrosion gradually constantly reduces the elastic force of spring, cause valve closing not tight, cause the perennial draingage phenomenon, thereby a large amount of tap water runs off in vain.
The purpose of this utility model is in order to overcome above-mentioned weak point of the prior art, is the flushing valve of power, water pressure self-closing formula structure with the mechanical lever and provide a kind of.
The purpose of this utility model is achieved in that it comprises the valve body that is inverted T-shape, this valve body top is water inlet, sidepiece is provided with delivery port, foot pedal apparatus is equipped with in the bottom, it is characterized in that having an intake gate on the valve body of water inlet inboard, the plug that the top of this intake gate is provided with seal gasket blocks up, the plug blocked shot affixed with the stifled middle part of this plug passes valve pocket, the valve pocket bottom is a rectangular cavities, described plug blocked shot passes the plug blocked shot slideway of this rectangular cavities upper surface middle part setting and enters this rectangular cavity, push rod in the foot pedal apparatus passes the push rod slideway of this rectangular cavities bottom surface middle part setting and enters this rectangular cavity, and corresponding with the plug blocked shot, the push rod peripheral seal is set with the elastic packing wrist of size and rectangular cavities appearance etc.
The utility model compared with prior art, because having replaced the elastic force that utilizes spring originally finishes the mode of damming of closing, press shutoff voluntarily to dam and the pressure that utilizes water is suitable downstream, therefore have simple in structurely, long service life, open light, the no pressure loss, cost reduction, characteristics such as water-tight.
The drawing explanation of accompanying drawing:
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
Valve body of the present utility model (2) is inverted T-shape, the top of this valve body (2) is water inlet (1), sidepiece is provided with delivery port (15), foot pedal apparatus is equipped with in the bottom, have an intake gate (5) on the valve body (2) of water inlet (1) inboard, the top of this intake gate (5) is provided with the plug stifled (3) of seal gasket (4), the plug blocked shot (6) affixed with this plug stifled (3) middle part passes valve pocket (14), valve pocket (14) bottom is a rectangular cavities (12), described plug blocked shot (6) passes the plug blocked shot slideway (13) of this rectangular cavities (12) upper surface middle part setting and enters this rectangular cavity (12), foot pedal apparatus is a lever-type structure, its push rod (10) passes the push rod slideway (11) of this rectangular cavities (12) bottom surface middle part setting and enters this rectangular cavity (12), and it is corresponding with plug blocked shot (6), push rod (10) peripheral seal is set with the elastic packing wrist (7) of size and rectangular cavities (12) appearance etc., pole in the foot pedal apparatus (9) is fixed in valve body (2) bottom, foot-driven lever (8) and this pole (9) hinge joint and corresponding with push rod (10).
Operating principle of the present utility model is: tap water flows into water inlet (1) by pipeline, this moment, plug stifled (3) formed close covering with intake gate (5) under hydraulic action, current stop at this point, depress foot-driven lever (8), foot-driven lever (8) is that fulcrum is done lever motion with the twisted axis of itself and pole (9), the other end of treadle (8) is upwards with push rod (10) jack-up, push rod (10) moves upward and drives plug blocked shot (6) interlock, the plug stifled (3) that combines as a whole with plug blocked shot (6) also moves upward, the motion of plug stifled (3) has formed the gap of plug stifled (3) with intake gate (5), at this moment tap water then enters valve pocket (14) along stifled (3) space on every side of plug by intake gate, flow out valve along delivery port (15), so far finished the overall process that starts the valve bath.Lifting the pin late gate when needs stop water closing.Because the lever power of Open valve disappears, plug stifled (3) also loses external force, rapidly intake gate (5) is obturaged under hydraulic action along the plug of pressing direction stifled (3) downstream, the sealing of push rod (10) is finished by elastic packing wrist (7) and is stoped the excessive of the interior water of valve pocket (14).
Claims (2)
1, the flushing valve of a kind of water pressure self-closing formula, comprise the valve body that is inverted T-shape, this valve body top is water inlet, sidepiece is provided with delivery port, foot pedal apparatus is equipped with in the bottom, it is characterized in that having an intake gate on the valve body of water inlet inboard, the plug that the top of this intake gate is provided with seal gasket blocks up, the plug blocked shot affixed with the stifled middle part of this plug passes valve pocket, the valve pocket bottom is a rectangular cavities, described plug blocked shot passes the plug blocked shot slideway of this rectangular cavities upper surface middle part setting and enters this rectangular cavity, push rod in the foot pedal apparatus passes the push rod slideway of this rectangular cavities bottom surface middle part setting and enters this rectangular cavity, and corresponding with the plug blocked shot, the push rod peripheral seal is set with the elastic packing wrist of size and rectangular cavities appearance etc.
2, water pressure self-closing formula according to claim 1 flushing valve is characterized in that the pole in the foot pedal apparatus is fixed in valve body lower portion, foot-driven lever and this pole hinge joint and corresponding with push rod.
