Technical Field
The utility model belongs to the technical field of gaseous fire extinguishing system, especially, relate to a decompression formula selector valve.
Background
All be equipped with selection valve and pressure relief device in IG541 gas fire extinguishing systems, the function of selection valve mainly is the selection protective area, ensures that the fire extinguishing agent can flow to corresponding protective area when putting out a fire, and pressure relief device's function is mainly to spout after reducing the pressure of the fire extinguishing agent of too high pressure again. Wherein, the selector valve and the pressure reducing device are respectively and independently arranged; the pressure reducing device is arranged in a pipeline and comprises an upper flange 1, a lower flange 4, two sealing gaskets 3 and a pressure reducing pore plate 2 which are clamped by a bolt pair 5 as shown in figure 1.
Thus, the following drawbacks exist in the prior art: the selector valve and the pressure reducing device are respectively and independently arranged, so that the installation is inconvenient; the pressure reducing device has a complex structure, is cumbersome to install, causes inconvenience in installation and increases cost.
Disclosure of Invention
An object of the utility model is to provide a decompression formula selection valve, with selection valve and pressure relief device integration in an organic whole, and reset pressure relief device's structure to realize installing convenient purpose. In order to achieve the above purpose, the utility model adopts the following technical scheme:
a kind of decompression type selective valve, including the selective valve body, the said selective valve body includes an inlet section, the end of the said inlet section forms an entrance point, the said inlet section is stuck and equipped with a decompression component and a hole and used the retaining ring; said circlip for bore is disposed adjacent said inlet end; the circlip for bore contacts the side of the pressure relief member adjacent the inlet end.
Preferably, the pressure reducing means is a pressure reducing orifice plate.
Preferably, the pressure reducing component is provided with a cylindrical pressure reducing hole and a truncated cone-shaped pressure reducing hole which are communicated with each other; said cylindrical pressure relief vent being disposed adjacent said inlet end; the small end of the truncated cone-shaped pressure reducing hole is connected with the cylindrical pressure reducing hole.
Preferably, a stepped hole is formed in the inner wall of the inlet section, and the stepped hole is matched with one side, far away from the inlet end, of the pressure reducing member.
Preferably, the inner wall of the inlet section is provided with a retainer groove matched with the retainer ring for the hole.
Compared with the prior art, the utility model has the advantages that: the pressure reducing component is additionally arranged in the selection valve, so that the selection valve and the pressure reducing device are integrated into a whole, and the installation is convenient; in addition, the pressure reducing device is only composed of a pressure reducing pore plate, so that the installation is convenient and the cost is reduced.
Drawings
FIG. 1 is a view showing a structure of a pressure reducing device installed in a piping according to the prior art;
fig. 2 is a structural diagram of the pressure-reducing type selector valve in an open state according to an embodiment of the present invention;
fig. 3 is a structural diagram of a pressure-reducing type selector valve in a closed state according to an embodiment of the present invention.
The pressure reducing valve comprises an upper flange 1, a pressure reducing pore plate 2, a sealing gasket 3, a lower flange 4, a bolt pair 5, a selection valve body 6, a pressure reducing component 7, a retainer ring for pores 8, a stepped hole 9, an inlet section 10 and an inlet end 11.
Detailed Description
The present invention will now be described in more detail with reference to the drawings, in which preferred embodiments of the invention are shown, it being understood that one skilled in the art could modify the invention herein described while still achieving the beneficial effects of the invention. Accordingly, the following description should be construed as broadly as possible to those skilled in the art and not as limiting the invention.
As shown in fig. 2 to 3, a pressure reducing type selector valve, which integrates a pressure reducing function and a function of the selector valve itself, includes a selector valve body 6, a pressure reducing member 7, and a retainer ring 8 for a hole.
The selection valve body 6 comprises an inlet section 10, the tail end of the inlet section 10 forms an inlet end 11 (air inlet end), and a pressure reducing component 7 and a hole retainer ring 8 are clamped in the inlet section 10; a circlip 8 is provided adjacent the inlet end 11 and the circlip 8 contacts the side of the pressure relief member 7 adjacent the inlet end 11.
Specifically, a stepped hole 9 is formed in the inner wall of the inlet section 10, and the stepped hole 9 is matched with one side, away from the inlet end 11, of the pressure reducing member 7. The stepped hole 9 functions to receive an axial force generated to the decompression member 7 when gas flows.
The inner wall of the inlet section 10 is provided with a retainer groove matched with the retainer ring 8 for the hole. The function of the circlip 8 is to prevent the pressure reducing member 7 from coming out of the selector valve body 6.
The pressure reducing component 7 is a pressure reducing pore plate, and a cylindrical pressure reducing pore and a truncated cone-shaped pressure reducing pore which are communicated with each other are arranged on the pressure reducing component 7; the cylindrical pressure relief vent is disposed proximate the inlet end 11; the small end of the truncated cone-shaped pressure reducing hole is connected with the cylindrical pressure reducing hole.
As known in the art, when the selector valve is operated, as shown in FIG. 2, the selector valve body 6 is opened, and the fire extinguishing agent enters the fire fighting pipeline from the side outlet of the selector valve body 6 through the pressure reduction orifice plate and is sprayed out of the protected area.
The above description is only for the preferred embodiment of the present invention, and does not limit the present invention in any way. Any technical personnel who belongs to technical field, within the scope that does not deviate from the technical scheme of the utility model, to the technical scheme and technical content that the utility model discloses do the change such as equivalent replacement or modification of any form, all belong to the content that does not break away from the technical scheme of the utility model, still belong to within the scope of protection of the utility model.
