Abstract
The utility model belongs to the technical field of mechanical equipment, and relates to an automobile part, in particular to a hand control valve suitable for control over the lifting of oil cylinders of various dump trucks. The technical problems of complex structure, poor sealing effect, high leakage rate and the like of the conventional hand control valve are solved. The hand control valve comprises a valve body and a handle arranged on the valve body. An air inlet is formed in one side of the bottom end of the valve body. Two air outlets are formed abreast in the other side of the bottom end of the valve body. The air inlet and the air outlets are connected with a joint assembly arranged in the valve body. The hand control valve has the advantages of rational design, simple structure, low equipment cost, high sealing performance, low leakage rate during use, and the like.
Description
Technical field
The utility model belongs to mechanical equipment technical field, relates to a kind of auto parts machinery, especially relates to a kind of hand control valve that various dump truck control oil cylinders go up and down that is fit to.
Background technique
Along with the development of society, people's living standard is progressive constantly, and automobile obtains application more and more widely as a kind of common transport facility.Not only equipment is coarse, build is heavy, raw materials consumption is big for the hand control valve that existing dump truck control oil cylinder goes up and down, and in manufacture process, operating handle needs to be connected with connecting sleeve earlier; And then with spool loading and unloading together, established the position of 2 limited screws on operating handle and the valve body after, brill distribution hole on connecting sleeve and spool; 2 position on the final establishment of ability operating handle, spool and the valve body makes that processing is required great effort, efficient is underground like this, is difficult to guarantee the accurate location of operating handle; Simultaneously; The area of contact of spool and valve body is less, has increased the chance of internal leakage, poor reliability.
In order to solve the problem that existing technology exists, people have carried out long-term exploration, have proposed solution miscellaneous.For example, the Chinese patent document discloses a kind of hand control valve [application number: 03212479.1], and this valve is on the basis of prior art; Improved the inside and outside structure of valve; To connect the termination and spool design is integral, the operating handle positioning hole leaves and is connecting on the termination, and the spool oilhole changes two into by original three; And valve body on oilhole, set up the high and low pressure pipe joint, in the circlip groove that the other end of spool has, be provided with circlip.
Such scheme has improved existing technology to a certain extent, has reduced the cost of production of hand control valve, has improved manufacturing efficiency, makes the stick position of hand control valve confirm that directly it is more accurate to locate.But still there are technical problems such as complex structure, poor, the easy leakage of sealing effect in this scheme.
Summary of the invention
The purpose of the utility model is to the problems referred to above, provides a kind of reasonable in design, simple in structure, and equipment cost is low, good seal performance, the hand control valve that is not easy to reveal.
For achieving the above object; The utility model has adopted following technical proposal: this hand control valve; Comprise valve body and be located at the handle on the valve body; Side in the valve body bottom is provided with suction port, and the opposite side in the valve body bottom is provided with two air outlets side by side, and described suction port is connected with all interior with the being located at valve body connector assembly in air outlet.
In above-mentioned hand control valve, described connector assembly comprises the slide that is located in the valve body and is connected with valve body, on slide, is connected with slide block, and described slide block is connected with the air outlet with suction port respectively.
Further, in above-mentioned hand control valve, described slide block both sides are provided with the rail slot of flanging.
Further, in above-mentioned hand control valve, be provided with through hole between described slide and the slide block.
As a kind of technological scheme of comparatively optimizing, in above-mentioned hand control valve, be provided with baffle plate between described handle and the valve body.
Compared with prior art, the advantage of this hand control valve is: reasonable in design, simple in structure, equipment cost is low, and good seal performance is not easy during use to produce and reveals.
Description of drawings
Fig. 1 is the structural representation that the utility model provides.
Fig. 2 is the sectional view that the utility model provides.
Among the figure, valve body 1, suction port 11, air outlet 12, handle 2, connector assembly 3, slide 31, slide block 32, rail slot 33, through hole 34, baffle plate 4.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Shown in Fig. 1-2; This hand control valve comprises valve body 1 and is located at the handle 2 on the valve body 1 that the side in valve body 1 bottom is provided with suction port 11; Opposite side in valve body 1 bottom is provided with two air outlets 12 side by side, suction port 11 and air outlet 12 all be located at valve body 1 in connector assembly 3 be connected.Suction port 11 and the setting of air outlet 12 and all be located at valve body 1 in the structure that is connected of connector assembly 3, can strengthen the sealability of valve body 1, avoid hand control valve valve body 1 generation leakage phenomenon in use.
Connector assembly 3 in the present embodiment comprises and is located in the valve body 1 and the slide 31 that is connected with valve body 1; On slide 31, be connected with slide block 32; Slide block 32 is connected with air outlet 12 with suction port 11 respectively, and slide block 32 both sides are provided with the rail slot 33 of flanging, is provided with through hole 34 between slide 31 and the slide block 32.The structure of the connector assembly 3 here can be selected according to actual needs.Be provided with baffle plate 4 between handle 2 and the valve body 1, the setting of baffle plate 4 can make does not influence the miscellaneous part normal operation when handle 2 is operated.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as valve body 1, suction port 11, air outlet 12, handle 2, connector assembly 3, slide 31, slide block 32, rail slot 33, through hole 34, baffle plate 4 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain the essence of the utility model more easily, and it all is contrary with the utility model spirit being construed to any additional restriction to them.
