By adopting aforementioned techniques scheme, the beneficial effects of the utility model are: this combined type push valve, can realize dismounting separation, the second valve seat part can split with valve body in opening cover plate, thereby it is cleared up separately, and will not pull down from pipeline by whole valve body, and the cost in when maintenance is lower.And by the separation setting of the first valve rod, the second valve rod, these three parts of spool, make to form between three the state of interlock transmission, be again independent various piece, thereby only need change certain part wherein in the time of maintenance, and assembling is also comparatively simple.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Now with embodiment, the utility model is further illustrated by reference to the accompanying drawings.
With reference to figure 1, the present embodiment provides a kind of combined pressure valve, comprise valve body 1, middle part on described valve body 1 is provided with valve seat 1a, described valve body is provided with water intake 11 and water outlet 12, on described valve body 1, be positioned at valve seat 1a place and be upwards provided with the outside opening 13 of connection, described opening 13 is provided with cover plate 2, on described cover plate 2, offer cover board hole 21, described valve seat 1a is provided with the second valve seat, described the second valve seat comprises housing 31, on described housing 31, be respectively equipped with the second water intake 311 and the second water outlet 312 that are communicated with water intake 11 and water outlet 12, the top of described housing 31 is provided with through hole 313, in described through hole 313, be provided with the first valve rod 32, the upper end of described the first valve rod 32 is provided with the first fixture block 321, in the periphery of described the first valve rod 32, between the first fixture block 321 and housing 31, be provided with the first spring 33, the lower end of described the first valve rod 32 is provided with the second fixture block 322, described the second fixture block 322 is provided with the first valve stem seal pad 323 for sealing through hole 313, the periphery that is positioned at the first valve rod 32 on described housing 31 is provided with connecting cylinder 34, the upper end that is positioned at the first valve rod 32 in described connecting cylinder 34 is provided with the second valve rod 35 that stretches out cover board hole 21, described the second valve rod 35 is provided with two seal rings 351 that seal with connecting cylinder 34, described housing 31 is provided with the connecting passage 36 that is communicated with connecting cylinder 34 and water outlet 12, the lower end that is positioned at the first valve rod 32 in described housing 31 is provided with spool 37, the upper end of described spool 37 is provided with the umbrella sealing circle 371 that can seal with housing 31, the lower end of described spool 37 is provided with the seal spool pad 372 that can seal with the second water outlet 312, described spool 37 is provided with the connecting port 373 of connection second water intake 311 and spool 37 upper spaces, the inner hollow of described spool 37, described hollow portion is provided with the 3rd spring 38 that connects housing 31 upper walls.
The outer side wall of described the second valve seat is provided with and two the second valve seat inserts 4 with valve seat 1a sealing, is arranged at respectively the upper/lower terminal of water intake 11.
One end that described the second valve rod 35 stretches out cover plate 2 is provided with briquetting 51, the periphery that the lower end of described cover plate 2 is positioned at cover board hole 21 is provided with card platform 52, in the periphery of described the second valve rod 35, between card platform 52 and briquetting 51, is provided with the second spring 53.Ka Tai is upper can be to having a set of cylinder, thereby make connecting cylinder be positioned at sleeve, thereby while making to press, connecting cylinder can be not cheap, makes the second valve seat more stable.
Working method of the present utility model is: in the time that this combined pressure valve is installed on pipeline, water intake one end is due to the effect of hydraulic pressure and the 3rd spring, can be by spool to pressing down, thereby water outlet is closed, and water can enter the upper space of spool from connecting port, thereby this space is filled to water, then keep steady state.After briquetting presses down, compression the second spring, thus make second valve masthead press the first valve rod, and the first valve rod is pressed down, the first valve rod presses down rear compression the first spring, thereby makes the second fixture block become opening state from the state that stops up through hole.Now the water of spool upper space can flow into water outlet from connecting passage, and now the space pressure on spool top diminishes, and presses under the effect of umbrella sealing circle on hydraulic pressure top, and spool upwards rises, thereby water outlet is communicated with water intake, valve opening.In the time that briquetting is unclamped, due to the effect of the second spring, briquetting, the second valve rod reset, and due to the effect of the first spring, the first valve rod resets.Thereby again stop up through hole, now spool top can be slowly full of water, and owing to there being the effect of the 3rd spring, thereby can make spool slowly press down, thus the second water outlet again sealed, thus throttle down.
This combined type push valve, can realize dismounting separation, the second valve seat part can be in opening cover plate splits with valve body, thereby it is cleared up separately, and will not pull down from pipeline by whole valve body, and cost when maintenance is lower.And by the separation setting of the first valve rod, the second valve rod, these three parts of spool, make to form between three the state of interlock transmission, be again independent various piece, thereby only need change certain part wherein in the time of maintenance, and assembling is also comparatively simple.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
