Abstract
The invention relates to a novel manual hydraulic valve, which comprises a valve body, a piston, an inner cover plate, a rubber gasket, a moveable gasket, a valve cover and a combined switch, wherein the inside of the valve body is provided with a water outlet which is provided with soft gasket; the upper side of the water outlet is provided with a piston of which the interior is a pressure cavity, wherein the lower part of the piston is provided with a hemisphere piston head made of a hard material, while the upper part is provided with a cylindrical piston body made of a soft material; the piston head is provided with a liquid inlet hole, and is communicated with the pressure cavity in the piston. Because the piston of the valve body is a hollow body of which the lower part is of a hardhemisphere shape, and the upper part is the soft cylinder, and the circumference of the valve body is not contacted with other valve bodies during working, the valve body can effectively reduce the load and abrasion born among parts, and improve the service life of the valve. The valve can be made of nonmetal materials, and not only can avoid the defect of generating rust water of the prior iron valves, but also can reduce the production cost. The novel manual hydraulic valve has the advantages of simple structure, flexible and convenient use, no water leakage, small maintenance and convenient popularization and application.
Description
[technical field] the present invention relates to a kind of valve, is a kind of novel manual hydraulic valve specifically.
[background technique] is existing to be applied to the valve in daily production and the life or to claim tap, most principles of drive fit extrusion friction that adopt opening and closing of control valve, with this principle control valve, following defect will appear in long valve after a while service time: the valve components wearing and tearing, cause the screw mandrel stripped thread, malfunctioning switch gets rusty and leaks between water and switch lever and the filler, above defect makes troubles for production and life, has influenced quality of product.
[summary of the invention] the objective of the invention is to provide a kind of rational in infrastructure for overcoming the above-mentioned defective of existing drive fit extrusion friction type valve, and cost is low, and is easy to manufacture, easy to use, avoids water resource waste and non-damageable novel manual hydraulic valve.
For realizing above-mentioned purpose, the present invention adopts following technological scheme: novel manual hydraulic valve, comprise valve body, piston, inner cover plate, rubber sheet gasket, movable holddown, valve gap, integral switch, in valve body, be provided with water outlet, water outlet is provided with soft packing ring, the top of water outlet is provided with the piston that there is the pressure cavity inside, this lower part of piston is the hemisphere type piston head that hard material is made, top is the cylinder type piston body that soft material is made, be provided with inlet opening on piston body, the pressure cavity in this inlet opening and the piston communicates; Between valve body inner cover plate and movable holddown, valve gap, be provided with rubber sheet gasket; Be provided with inner cover plate above piston, inner cover plate is provided with switch hole and pod apertures, forms water channel between pressure cavity and inner cover plate switch hole, inner cover plate pod apertures, piston pod apertures and valve body pod apertures and the inlet opening.Above inner cover plate, be provided with rubber sheet gasket, the rubber sheet gasket top is provided with valve gap, valve gap is a concave structure, be provided with the movable holddown that an end contacts with rubber sheet gasket at the center of pit, the other end of movable holddown with contact/separate with integral switch that valve gap is connected as a single entity, regulate movable holddown by integral switch, can reach out/close the purpose of valve.
Compare with existing valve, manual hydraulic valve of the present invention has following advantage: 1, owing to be provided with rubber sheet gasket in the valve body of the present invention, this pad can effectively be isolated liquid in the valve and the component more than the rubber sheet gasket, played the effect of valve seal, solve a difficult problem that needs stuffing in the valve, played the effect that valve is opened and closed again.2, because the piston of valve body is a hollow body, the bottom is that hard is hemispherical, top is soft cylindrical body, and do not contact around when moving up and down with other valve bodies, only the spheroid bottom surface contacts with soft packing ring on the water outlet when valve closing, therefore the load and the wearing and tearing that can effectively reduce between the component to be born, the working life that can improve this valve, and use flexibly, convenient.3, this valve can all adopt nonmetallic material to make, and both can avoid the defective of the rust of irony valve generation in the past water, can reduce production costs again, and is easy to utilize.
[description of drawings] the present invention is further described below in conjunction with the drawings and specific embodiments.
Accompanying drawing is a structural representation sectional view of the present invention.
Among the figure: 1, valve body, 2, piston, 3, inner cover plate, 4, rubber sheet gasket, 5, movable holddown, 6, valve gap, 7, integral switch, 8, inlet opening, 9, the pressure cavity, 10, switch hole, 11, piston pod apertures, 12, the inner cover plate pod apertures, 13 valve body pod apertures, 14, water outlet.
[embodiment]
With reference to accompanying drawing: be provided with water outlet 14 in plastics valve body 1, this water outlet is provided with soft rubber washer; Be provided with the piston 2 of pressure cavity above water outlet 14, this lower part of piston is the hemisphere type piston head that duroplasts is made, and top is the cylinder type piston body that Polypropylence Sheet or waterproof cloth or rubber are made; On the cylinder type piston body on piston 2 tops, be provided with inlet opening 8, the mounting plate on piston top is provided with pod apertures 11, pressure cavity 9 in this inlet opening 8 and the piston communicates, and piston 2 has only piston head to contact with the soft washer on the described water outlet 14, does not contact with other position of valve body; Above piston, be provided with inner cover plate 3, inner cover plate 3 is provided with switch hole 10 and pod apertures 12, forms water channel between the pod apertures 11 on pressure cavity 9 in the piston and the switch hole 10 on the inner cover plate and pod apertures 12, the piston mounting plate and valve body pod apertures 13 and the inlet opening 8.Between valve body inner cover plate 3 and movable holddown 5, valve gap 6, be provided with rubber sheet gasket 4, this rubber sheet gasket top is provided with the valve gap 6 of spill, the lower end of valve gap 6 is fastened on the valve body 1, the outer end of valve gap is connected with integral switch 7, a movable holddown 5 is housed in the middle of the groove of valve gap 6, the lower end of this movable holddown contacts with rubber sheet gasket 4, the protruding key of the upper end of movable holddown 5 and integral switch 7 is close, advance and retreat by manual switchgroup 7, make the protruding key of integral switch 7 push down or leave movable holddown 5, reach the purpose of on/off valve.
