Abstract
The utility model discloses a large-flow speed regulating valve, which comprises a main valve body, wherein a valve rod is rotatably arranged in the main valve body, a valve core is arranged in the inner part of a port at the lower end of the main valve body, the valve core is connected with the lower end of the valve rod, a single sealing ring is arranged at the outer side of the valve core, the single sealing ring can prevent gas leakage, and the air tightness of the speed regulating valve is improved; the valve rod and the valve core are arranged in the main valve body, so that the phenomenon of looseness caused by vibration of equipment in the use process of the speed regulating valve can be prevented, and the stability of the speed regulating valve is improved; through setting up the ring, can make quick-operation joint and main valve body carry out whole cladding formula and be connected, make the connection that can stabilize be in the same place, be difficult for breaking away from.
Description
Technical Field
The utility model relates to a governing valve field specifically is a large-traffic governing valve.
Background
The speed governing switch of current valve exposes outside the product, and the choke valve produces not hard up phenomenon because the vibrations of equipment in the use, and the speed governing of current structure has the not high problem of speed governing precision simultaneously, and the speed governing switch is too nimble not hard up, and the interface part's of being connected with external pipeline stability is relatively poor, adopts the jump ring, belongs to line contact, can not satisfy current demand.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a large-traffic governing valve to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a large-traffic governing valve, includes the main valve body, the internal rotation of main valve installs the valve rod, and the internal portion of lower port is provided with the case under the main valve body, and the case is connected with the valve rod lower extreme, the case outside is provided with the individual sealing washer, the main valve body outside is provided with the ring, and ring right-hand member an organic whole is connected with vice valve body, the inside release ring that is provided with of vice valve body right-hand member opening, release ring left end and vice valve body inner wall junction are provided with dual seal circle, be provided with the retaining ring on the main valve body lateral wall, the retaining.
Compared with the prior art, the beneficial effects of the utility model are that: the valve rod and the valve core are arranged in the main valve body, so that the phenomenon of looseness caused by vibration of equipment in the use process of the speed regulating valve can be prevented, and the stability of the speed regulating valve is improved; through setting up the ring, can make quick-operation joint and main valve body carry out whole cladding formula and be connected, make the connection that can stabilize be in the same place, be difficult for breaking away from.

In the figure: 1-main valve body, 2-valve rod, 3-valve core, 4-single sealing ring, 5-circular ring, 6-auxiliary valve body, 7-retainer ring, 8-release ring and 9-double sealing ring.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example 1
Referring to fig. 1, in the embodiment of the present invention, a large flow rate speed regulating valve includes a main valve body 1, a valve rod 2 is rotatably installed inside the main valve body 1, a valve core 3 is installed inside a lower port of the main valve body 1, the valve core 3 is connected to a lower end of the valve rod 2, a single sealing ring 4 is installed outside the valve core 3, the single sealing ring 4 can prevent gas leakage and improve the air tightness of the speed regulating valve, a circular ring 5 is installed outside the main valve body 1, a sub-valve body 6 is integrally connected to a right end of the circular ring 5, a release ring 8 is installed inside an opening of a right end of the sub-valve body 6, a double sealing ring 9 is installed at a connection position between a left end of the release ring 8 and an inner wall of the sub-valve body 6, so as to further improve the air tightness of the speed regulating valve, a retaining ring 7 is installed on an outer side wall of the main valve body 1, through releasing ring 8, can make it carry out high-speed joint with the pipeline, later rotatable valve rod 2, it rotates to drive case 3, carry out the speed governing to it, through setting up valve rod 2 and case 3 inside main valve body 1, can prevent that the speed governing valve is at the in-process that uses, produce not hard up phenomenon because of equipment vibrations, improve the stability of this speed governing valve, through setting up ring 5, can make quick-operation joint carry out whole cladding formula with main valve body 1 and be connected, make the connection that it can stabilize together, be difficult for breaking away from.
The working principle of the embodiment is as follows: through releasing ring 8, can make it carry out high-speed joint with the pipeline, later rotatable valve rod 2, it rotates to drive case 3, carry out the speed governing to it, through setting up valve rod 2 and case 3 inside main valve body 1, can prevent that the speed governing valve is at the in-process that uses, produce not hard up phenomenon because of equipment vibrations, improve the stability of this speed governing valve, through setting up ring 5, can make quick-operation joint carry out whole cladding formula with main valve body 1 and be connected, make the connection that it can stabilize together, be difficult for breaking away from.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
