Abstract
The utility model relates to an adjusting valve used for being connected to the exhaust output end of a gas compressor, which comprises a pressure adjusting bolt (1), a stroke adjusting bolt (3), a spring (6), a valve rod (8) and a valve body (5), wherein, a gas inlet hole of the valve body (5) is a circular hole. The gas outlet end of the gas inlet hole is communicated with a circular hole of a valve plug, the spherical valve plug (9) is arranged in the circular hole of the valve plug, and the valve rod (8) is pressed on the valve plug (9). The utility model has the advantages of simple structure, low processing cost and small adjusting pressure difference, and the adjusting pressure difference is only one third to one fourth of that of the prior art.
Description
The utility model relates to gas valve, and especially a kind of being connected on the gas compressor output terminal just opens and export the variable valve of gas when the gas compressor output gas pressure reaches set pressure.
Existing above-mentioned variable valve, as the TJ type variable valve that the applicant produces, the sealing of this variable valve is to adopt the metal flat sealing, its valve plug and sealing surface of seat are equal must grinding and then be assembled in the valve body; In order to guarantee the applying of two sealing surfaces, sphere must be processed in the side that its valve plug cooperates with valve body, and valve plug must adopt bulb to connect with valve rod, and its structure of the variable valve of this spline structure is complicated, the requirement on machining accuracy height, and sealing is good inadequately, and it is big to regulate pressure reduction.
The purpose of this utility model provide a kind of simple in structure, processing cost is low, regulate the little variable valve of pressure reduction.
For achieving the above object, scheme of the present utility model is: it comprises pressure adjusting bolt, stroke adjustment bolt, spring valve rod and valve body, it is characterized in that: the air admission hole of described valve body is a circular port, the outlet side of this air admission hole is communicated with the plug holes of a circle, spherical valve plug is housed in the plug holes, described valve rod is pressed on the valve plug, when valve plug is subjected to the acting force of valve rod and overcomes thrust gas from air admission hole, valve plug just is pressed on the port of air admission hole, blocks the passage of valve body air admission hole and vent port; When valve plug was subjected to from the thrust gas of air admission hole and overcomes the acting force of valve rod, valve plug just left the port of giving vent to anger of air admission hole, when the valve plug center goes out to the plug holes port.Just open the passage of valve body air admission hole and vent port.Described valve plug can be made with hard materials such as steel balls, and described valve body can be made with softer materials such as brass.
Described stroke adjustment bolt and valve body connection part are equipped with O-ring seal.
Owing to adopt such scheme, the utility model is compared with prior art (the TJ type variable valve that the applicant produces) has following advantage:
1, simple in structure, handling ease, cost is low.The valve plug of prior art is that the side is that sphere, bottom surface are the structure that there is circular blind hole at plane, center, and valve plug of the present utility model is a ball structure; The valve rod of prior art and the end that connects of valve plug are a bulb shape of protruding, and valve rod of the present utility model its only be that a taper hole or circular hole get final product with the end that connects of valve plug; In addition, because the utility model adopted ball face sealing, the valve seat that cooperates with valve plug need not resemble and grind the rear the prior art and be installed in the valve body, and can directly be shaped on valve body.Thereby structure of the present utility model is corresponding to be simplified widely, and handling ease, processing cost reduce more than one times.
2, adjusting pressure reduction is little.Through test, regulate pressure reduction and can reach 0.05Mpa, only regulate 1/3 to 1/4 of pressure reduction for prior art.
Below in conjunction with accompanying drawing embodiment structure of the present utility model is described in further detail:
Fig. 1 is the structural representation of the utility model embodiment.
Shown in Figure 1, among the utility model embodiment, valve body 5 is made by brass, it is provided with air intake opening and gas outlet, is connected with inlet suction port 11 and collar nut 12 at the air intake opening place, and circular air admission hole is arranged in the valve body 5, inlet end at air admission hole is equipped with filter screen 10, in case foreign material enter gas passage in the valve; The diameter that the outlet side of air admission hole is communicated with a circle is than the valve plug 9 that the sphere that steel make is housed in the big slightly plug holes plug holes of valve plug diameter, the stroke adjustment bolt 3 of control valve plug stroke is housed in the valve body 5, stroke adjustment bolt 3 outer being equipped with connect fastening check nut 4 with stroke adjustment bolt 3 with valve body 5, regulate between bolt 3 and the valve body 5 O-ring seal 7 is housed, in case leak-stopping gas; Stroke adjustment bolt 3 is a hollow-core construction, pressure is housed in it regulates bolt 1, spring 6 and valve rod 8, outside pressure is regulated bolt 1, be equipped with and pressure is regulated bolt 1 connect fastening check nut 2 with stroke adjustment bolt 3, valve rod 8 is being pressed under the effect of spring 6 on the valve plug 9, there is a bellmouth termination that valve rod 8 is pressed in valve plug 9, and this hole plays the role of positioning to valve plug 9.When reacting force that valve rod 8 power on the valve plug 9 that acts on forms greater than the gas differential pressure that acts on the valve plug 9, valve plug 9 just is pressed on the port of giving vent to anger of air admission hole in the valve body 5, blocks the passage of valve body 5 air admission holes and venthole; When reacting force that valve rod 8 power on the valve plug 9 that acts on forms less than the gas differential pressure that acts on the valve plug 9, valve plug 9 just leaves the port of giving vent to anger of air admission hole in the valve body 5, at this moment, the lifting surface area that the gas at air intake opening place acts on valve plug 9 increases to the centre of sphere cross section of valve plug 9 rapidly, act on the i.e. increase rapidly of reacting force that the gas differential pressure on the valve plug 9 forms, valve plug 9 moves rapidly its center is gone out to the plug holes port, and to the termination that is pressed in stroke adjustment bolt 3, open the passage of valve body 5 air admission holes and venthole simultaneously; When the pressure differential of valve body 5 air admission holes and venthole diminishes, during reacting force that valve rod 8 power on the valve plug 9 that acts on forms greater than the gas differential pressure that acts on the valve plug 9, valve plug 9 is just returned again to plug holes and is pressed on the port of giving vent to anger of air admission hole in the valve body 5, blocks the passage of valve body 5 air admission holes and venthole.
The valve body 5 that valve plug 9 brass lower with adopting hardness that adopts steel to make is made matches, and can make valve plug 9 reliable with the sealing of the port of giving vent to anger of valve body 5 air admission holes, thereby the further sensitivity of the utility model action reduces it and regulates pressure reduction.
