Abstract
The utility model discloses a hydraulic valve. The hydraulic valve comprises an operating handle, a valve element and a valve body. The operating handle is connected with the valve body through an oil storing groove. The valve element penetrates through the operating handle to be connected with the valve body, sealing oil is arranged between the valve body and the valve element, one end of the valve element is provided with a fastening sheath, one end of the valve body is provided with a swivel nut and an oil outlet, the valve body is provided with an oil outlet channel, the oil outlet channel is connected with the swivel nut, the oil outlet channel is provided with a one-way control valve, and the other end of the valve element is provided with a valve cover. The hydraulic valve is simple in structure, low in failure rate and convenient to dismount and maintain, and great convenience is brought through cooperation of all components. When the amount of foreign gases in a tank is large, the sealing oil is pushed out of the valve body, falls into the annular oil storing groove and flows back into the valve body through a pipeline, the sealing effect is good, and remote control can be achieved through the external operating handle.
Description
Technical field
The utility model relates to a kind of valve body, is specifically related to a kind of hydrovalve.
Background technique
Hydrovalve is mounted in a kind of safety installations on oil storage tank, is fixed together by valve seat and valve body, and valve bonnet covers on valve body, sealing oil is housed in valve body, by keeping apart with tank in tank, plays the effect of sealed oil tank by sealing oil outward, if foreign gas is less in oil, can discharge by hydrovalve, if foreign gas is too much, sealing oil can be shifted onto outside valve body with foreign gas, oil is tailed off, sealing effect variation, air enters in tank, has potential safety hazard; The design of valve body is arranged on handle on valve body conventionally, when special circumstances, cannot realize strange land operation, is not easy to focus on operating table and controls.Therefore, need to provide a kind of new technological scheme to solve above-mentioned technical problem.
Model utility content
The purpose of this utility model is to provide a kind of hydrovalve, and failure rate is low and detachable maintaining are convenient, by cooperatively interacting and bring convenience between each parts.
For solving the problems of the technologies described above, under the technological scheme basis that model utility is taked: a kind of hydrovalve, comprise operating grip, spool and valve body, described operating grip is connected with valve body by holding oil groove, described spool runs through operating grip and is connected with valve body, between described valve body and spool, be provided with sealing oil, described spool one end is provided with fastening sheath, one end of described valve body is provided with swivel nut, oil outlet, on described valve body, be provided with oil discharge passage, described oil discharge passage is connected with swivel nut, on described oil discharge passage, be provided with one-way control valve, the described spool the other end is provided with valve bonnet.
As preferably, described oil discharge passage, swivel nut and hold oil groove and mutually removably connect by bolt and valve body.
As preferably, described valve body is detachable.
As preferably, between described oil discharge passage and swivel nut, be provided with gasket seal.
The utility model is simple in structure, and failure rate is low and detachable maintaining are convenient, by cooperatively interacting and bring convenience between each parts; When in tank, foreign gas is many, sealing oil is shifted onto outside valve body, sealing oil falls into annular and holds in oil groove, get back to again in valve body by pipeline, and good sealing effect, external operating grip can be realized strange land manipulation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Embodiment
For technological means, creation characteristic that model utility is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth model utility.
With reference to Fig. 1, this embodiment is by the following technical solutions: a kind of hydrovalve, comprise operating grip 1, spool 8 and valve body 9, described operating grip 1 is connected with valve body 9 by holding oil groove 3, described spool 8 runs through operating grip 1 and is connected with valve body 9, between described valve body 9 and spool 8, be provided with sealing oil 10, described spool 8 one end are provided with fastening sheath 5, one end of described valve body 9 is provided with swivel nut 2, oil outlet 6, on described valve body 9, be provided with oil discharge passage, described oil discharge passage is connected with swivel nut 2, on described oil discharge passage, be provided with one-way control valve 7, described spool 8 the other ends are provided with valve bonnet 4.
It should be noted that described oil discharge passage, swivel nut 2 and hold oil groove 3 and mutually removably connect by bolt and valve body.
It should be noted that described valve body 9 is detachable.
It should be noted that between described oil discharge passage and swivel nut 2 and be provided with gasket seal.
The utility model is simple in structure, and failure rate is low and detachable maintaining are convenient, by cooperatively interacting and bring convenience between each parts; When in tank, foreign gas is many, sealing oil is shifted onto outside valve body, sealing oil falls into annular and holds in oil groove, get back to again in valve body by pipeline, and good sealing effect, external operating grip can be realized strange land manipulation.
More than show and described the basic principle of model utility and the advantage of major character and model utility.The technician of the industry should understand; model utility is not restricted to the described embodiments; the principle that model utility is just described of describing in above-described embodiment and specification; do not departing under the prerequisite of model utility spirit and scope; model utility also has various changes and modifications, and these changes and improvements all fall within the scope of claimed model utility.The claimed scope of model utility is defined by appending claims and equivalent thereof.
