Abstract
The utility model relates to a stacked direct-acting-type pressure reducing valve, which comprises a valve body and a valve core installation passage which is arranged in the valve body. Sealing bolts are arranged at the two ends of the valve core installation passage, a valve core structure is arranged in the valve core installation passage, the valve core structure comprises a compression spring which is sheathed on the sealing bolt on one side of the valve body and a valve core which is connected with the end part of the compression spring, and a liquid inlet passage and a liquid outlet passage are respectively arranged on the two sides of the valve core on the valve body; a pressure regulating device is arranged on one side of the sealing bolt which is connected with the compression spring and the pressure regulating device is a threaded rod which is connected with the sealing bolt. By driving the sealing bolt to move forwards or backwards through the rotation of the threaded rod, the compression degree of the compression spring which is connected with the sealing bolt is controlled, the regulation of the pressure of liquid in the liquid outlet passage is realized, the diaphragm of the traditional pressure reducing valve is replaced by the valve core, the structure is simple and the service life of the pressure reducing valve is prolonged.
Description
Technical field
The utility model relates to a kind of reduction valve, the straight ejector half reduction valve of especially a kind of overlapping.
Background technique
Reduction valve is a kind of special arrangement of automatic reduction working pressure of pipeline, and it can be reduced to hydraulic pressure higher pipeline before valve the required level of pipeline after valve.Reduction valve is widely used in tall building, too high region, mine and other occasions of city water-supply pipe network hydraulic pressure, to guarantee respectively to obtain suitable service hydraulic pressure and flow with water spot in water supply system.The basic role principle of reduction valve is, by valve inner flow passage, the local resistance of current is reduced to hydraulic pressure, and the scope that hydraulic pressure falls is by connecting the film of flap or the import and export differential water pressures of piston both sides regulates automatically.
At present, on market, existing straight ejector half reduction valve adopts diaphragm more, and the working life of diaphragm is short, effect of easing stress is bad, and it is stable not that the liquid outlet channel of existing reduction valve goes out hydraulic coupling, cannot monitor at any time, and the going out hydraulic coupling and cannot regulate of liquid outlet channel, can only be a steady state value.
Model utility content
The purpose of this utility model is that degree of regulation is high, the straight ejector half reduction valve of overlapping of long service life in order to solve the existing defect of the straight ejector half reduction valve of overlapping in prior art, to provide one to adjust voluntarily hydraulic coupling.
To achieve these goals, the technical solution adopted in the utility model is:
The straight ejector half reduction valve of a kind of overlapping, comprise valve body, the spool being arranged in this valve body is installed passage, the two ends that this spool is installed passage are equipped with sealing bolt, in installing passage, this spool is provided with valve core structure, described valve core structure comprises the Compress Spring being sleeved on described valve body one side sealing bolt, and with the spool that this Compress Spring end is connected, the both sides that are positioned at this spool on described valve body are respectively equipped with feed pathway and liquid outlet channel; One side of the sealing bolt being connected with described Compress Spring is also provided with pressure regulator.
The straight ejector half reduction valve of above-mentioned a kind of overlapping, described pressure regulator is the threaded stem being connected with described sealing bolt, drives described sealing bolt to move forward and backward by the rotation of this threaded stem.
The straight ejector half reduction valve of above-mentioned a kind of overlapping, on described valve body, the joint of Compress Spring and spool is provided with spring chamber.
The straight ejector half reduction valve of above-mentioned a kind of overlapping, is also provided with pressure gauge connection on described valve body.
The straight ejector half reduction valve of above-mentioned a kind of overlapping, described pressure gauge connection is connected with described liquid outlet channel by connecting passage.
The beneficial effects of the utility model are: this reduction valve is controlled the flexible of sealing bolt by the rotation of threaded stem, thereby control the compression degree of the Compress Spring being attached thereto, realize the adjusting to fluid pressure in liquid outlet channel, replace the diaphragm of traditional relief valve with spool, in simple in structure, also increased the working life of reduction valve.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
Embodiment
For making that structure characteristic of the present utility model and effect of reaching are had and further understand and be familiar with, coordinate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:
As shown in Figure 1, the straight ejector half reduction valve of a kind of overlapping, comprise valve body 1, the spool being arranged in this valve body 1 is installed passage 2, the two ends that this spool is installed passage 2 are provided with sealing bolt 3 and sealing bolt 4 respectively, in installing passage 2, this spool is provided with valve core structure, as improvement of the present utility model, valve core structure comprises the Compress Spring 5 being sleeved on valve body 1 one side sealing bolts 4, the spool 6 being connected with these Compress Spring 5 ends, the both sides that are positioned at this spool 6 on valve body 1 are respectively equipped with feed pathway 7 and liquid outlet channel 8, are provided with oil circuit control 13 in spool; Further improve as the utility model, a side of the sealing bolt 4 being connected with Compress Spring 5 is also provided with pressure regulator 9.
The threaded stem of pressure regulator 9 for being connected with sealing bolt 4, drives sealing bolt 4 to move forward and backward by the rotation of this threaded stem, thereby controls the compression degree of the Compress Spring 5 being attached thereto.
Preferably, on valve body 1, the joint of Compress Spring 5 and spool 6 is provided with spring chamber 10, is also provided with pressure gauge connection 11 on valve body 1, and pressure gauge connection 11 is connected with liquid outlet channel 8 by connecting passage 12.
In position of rest, this reduction valve is often opened, fluid can freely flow to liquid outlet channel 8 from feed pathway 7, liquid outlet channel 8 internal pressure oil act on the left side of Compress Spring 5 opposite spools 6 through oil circuit control 13, in the time that liquid outlet channel 8 internal pressure oil exceed the setting value of Compress Spring 5, control spool 6 and move in control band, it is constant that the pressure of liquid outlet channel 8 keeps, and the pressure oil that now spool is installed in passage 2 flows back to fuel tank by spring chamber 10.
This reduction valve is controlled the flexible of sealing bolt 4 by the rotation of threaded stem, thereby control the compression degree of the Compress Spring 5 being attached thereto, change the setting value of Compress Spring 5, realize the adjusting to liquid outlet channel 8 interior fluid pressures, replace the diaphragm of traditional relief valve with spool 6, in simple in structure, also increased the working life of reduction valve.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what in above-described embodiment and specification, describe is principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
