Abstract
The utility model discloses a marine right angle choke valve has valve body, valve rod, has orthogonal second channel and first passageway in the valve body, the lower extreme of valve rod is connected with the valve disc, and the valve disc lies in the upside of second channel, and the valve disc also lies in the lateral part of first passageway simultaneously, and the downside of valve disc is provided with the throttle valve barrel, and the inner chamber of throttle valve barrel communicates with each other with the second channel, and the lateral wall of throttle valve barrel has the orifice that pierces through its lateral wall, and the outside cover of throttle valve barrel is equipped with the sealing washer. The outside cover of top valve rod is equipped with the jam nut, the lower part of jam nut lies in between valve rod and the valve body, and the outside cover on jam nut top is equipped with gland nut. The utility model discloses the beneficial effect who has: novel structure is unique, install simple and convenient, applicable steam pipework on boats and ships. Because steam only could circulate through the orifice, has fine throttle effect, the while also can keep fine leakproofness, can not leak, has also improved the life of choke valve.
Description
Technical field
This utility model relates to valve technology field, is specifically related to a kind of right-angle throttle valve peculiar to vessel.
Background technology
Choke valve is mainly used in regulating flow or blocking medium, regulates rate-of flow and pressure generally by changing traffic channel area, therefore, is used on the pipeline requiring bigger Pressure Drop more.
A kind of right-angle throttle valve disclosed in the patent that application number is 201210213379.50, including valve body, valve gap, valve rod and spool, valve gap is connected with valve body and fixing, bonnet central is provided with valve rod, valve rod lower end is provided with spool, spool rotates with valve rod and moves up and down and be tightly connected with body cavity formation, and described valve rod upper end is provided with valve bonnet, and valve bonnet is set on valve rod and can rotate by band ovable valve stem；Spool is set to cone, and spool face is provided with wear-resisting carburized layer, and valve bonnet lower end is near valve gap upper surface.Relative to prior art, the upper end of valve rod of the present invention is with valve bonnet, and impurity etc. is not easily accessible in the screw thread of valve rod, and the contact surface of spool and body cavity is provided with wear-resisting carburized layer, and life-time service is not easy to abrasion, thus improve the service life of right-angle throttle valve.Present configuration is compact, long service life, good sealing effect.
Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, it is provided that a kind of simple in construction, good seal performance right-angle throttle valve peculiar to vessel.
In order to reach the purpose of this utility model, technical scheme is as follows:
A kind of right-angle throttle valve peculiar to vessel, there is valve body, valve rod, there is in valve body mutually perpendicular second channel and first passage, it is characterised in that the lower end of described valve rod is connected to valve disc, valve disc is positioned at the upside of second channel, valve disc also is located at the sidepiece of first passage simultaneously, and the downside of valve disc is provided with throttling valve pocket, and the inner chamber of throttling valve pocket communicates with second channel, the sidewall of throttling valve pocket has the throttle orifice penetrating its sidewall, and the outer sheath of throttling valve pocket is provided with sealing ring.
Further, the outer sheath of upper part valve rod is provided with jam nut, and the lower part of described jam nut is between valve rod and valve body, and on jam nut, the outer sheath of part is provided with clamp nut.
This utility model has the advantages that
Novel structure is unique, installs simple and convenient, is applicable to the steam pipework on boats and ships.Owing to steam only could be circulated by throttle orifice, there is good restriction effect, also can keep good sealing simultaneously, will not leak, also improve the service life of choke valve.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model right-angle throttle valve peculiar to vessel.
Detailed description of the invention
Below in conjunction with embodiment, this utility model is further described, but protection domain of the present utility model is not limited solely to embodiment.
Shown in Fig. 1, a kind of right-angle throttle valve peculiar to vessel, there is valve body 6, valve rod 1, there is in valve body 6 mutually perpendicular second channel 9 and first passage 8, first passage 8 horizontally set, second channel 9 is vertically arranged, and valve rod 1 is also vertically arranged.The outer sheath of upper part valve rod 1 is provided with jam nut 3, and the lower part of described jam nut 3 is between valve rod 1 and valve body 6, and on jam nut 3, the outer sheath of part is provided with clamp nut 2, clamp nut 2 and jam nut 3 and jointly plays the effect of firm valve rod 1.
The upper end of valve rod 1 is provided with the handle 10 of rotation valve rod 1, the lower end of valve rod 1 is connected to valve disc 4, valve disc 4 also is located at the upside of second channel 9, valve disc 4 also is located at the left side of first passage 8 simultaneously, the downside of valve disc 4 is provided with throttling valve pocket 5, and throttling valve pocket 5 also is located on the upside of second channel 9, and the inner chamber of throttling valve pocket 5 communicates with second channel 9, having, on the sidewall of throttling valve pocket 5, the throttle orifice 7 penetrating its sidewall, therefore throttling valve pocket 5 is the structure of an annular.When being in the state of Fig. 1, second channel 9 and first passage 8 are not turned on, and steam cannot circulate；Now turning handle 10, make to move on valve rod 1, and valve rod 1 rotates simultaneously, making throttle orifice 7 rotate to the right, until throttle orifice 7 communicates with first passage 8, steam is from first passage 8, internal to throttling valve pocket 5 by throttle orifice 7, then pass in second channel 9, it is achieved pipeline turns on.
The outside of throttling valve pocket 5 is also arranged with sealing ring 11, and when the valve pocket 5 that throttles rotates and moves up and down, sealing ring 11 can be close to valve body 6 inner chamber, keeps the sealing of whole choke valve.
Last it is noted that above example only in order to this utility model is described and and technical scheme described by unrestricted this utility model, therefore, although this utility model is had been carried out describing in detail by this specification with reference to each above-mentioned embodiment, but, it will be understood by those within the art that, still this utility model can be modified or equivalent replacement, and all are without departing from the technical scheme of spirit and scope of the present utility model and improvement thereof, it all should be encompassed in right of the present utility model.
