Abstract

The utility model discloses a large flow throttle valve, which mainly comprises a valve body, a valve pocket, a valve core component, a valve rod seat and a valve rod, wherein the valve core component is installed into the centre hole of the valve body from the top of the valve body and is fixedly riveted by a special tool, the valve body and the valve core component form a valve body component which is compressed into the bottom hole of the valve pocket from the lower part of the valve pocket, the valve rod is screwed into the screw hole of the valve rod seat, the valve rod seat is compressed into the upper part hole of the valve pocket from the upper part of the valve pocket, and the valve rod is provided with a regulating wheel and a locking hole. The valve core component is installed in the valve body from the upper part of the valve body, so that the problem that the valve core size is limited by the size of external threads of the valve body can be avoided, the product flow can be increased doubly, at the same time, the valve body in the prior art is changed into the valve rod seat and the lower valve body, therefore, the use of the metal material can be reduced so as to save the cost.

Description

Big flow throttle valve

Technical field

The utility model relates to a kind of throttle valve, especially a kind of big flow throttle valve.

Background technique

The valve body of like product mostly is monolithic construction in the market, valve body lower portion is an outside thread, threaded interior processing is outside portalled, spool is contained in the hole of threaded interior in addition, because be subjected to its interior hole dimension of outside thread size restrictions less relatively, the spool of packing into wherein is also just quite less, causes flow less relatively, so because valve body is that monolithic construction metallic material (mostly being lead brass) consumption is relatively large, product cost is higher relatively.

The model utility content

At the deficiencies in the prior art, the purpose of this utility model is to provide a kind of flow big, big flow throttle valve with low cost.

The utility model takes following technological scheme to realize its purpose: a kind of big flow throttle valve, mainly comprise valve body, mangetic core assembly, valve pocket, valve rod base and valve rod etc., the mangetic core assembly valve body center hole of packing into from the top of valve body wherein, and with special tool with its riveting jail, the valve component that valve body and mangetic core assembly are formed is pressed into the valve pocket base apertures from the valve pocket bottom, valve rod screws in the valve rod base screw, and valve rod base is pressed into the valve pocket upper hole from top, and regulating wheel and locking wheel are installed on the valve rod.

The beneficial effect that technological scheme reached that adopts the utility model to provide is: mangetic core assembly is packed into from top in the valve body, can avoid the spool size to be subjected to this problem of valve body outside thread size restrictions, and then product flow is multiplied, valve rod base and lower body separate structure can effectively reduce the use of metallic material, reduce product cost.

Description of drawings

Fig. 1 is the utility model structural representation.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail:

As shown in Figure 1, be the utility model structural representation, a kind of big flow throttle valve, mainly comprise valve body 7, mangetic core assembly 6, valve pocket 5, valve rod base 3 and valve rod 4 etc., the mangetic core assembly 6 valve body center hole of packing into from the top of valve body 7 wherein, and with special tool with its riveting jail, the valve component that valve body 7 and mangetic core assembly 6 are formed is pressed into valve pocket 5 base apertures from valve pocket 5 bottoms, valve rod 4 screws in valve rod base 3 screws, valve rod base 3 is pressed into valve pocket 5 upper holes from top, and regulating wheel 1 and locking wheel 2 are installed on the valve rod 4.As a kind of improvement, in mangetic core assembly 6 pack into valve body 7 from valve body 7 tops, can avoid the spool size to be subjected to this problem of valve body outside thread size restrictions, and then product flow is multiplied, change valve body 7 of the prior art into valve rod base 3 and 7 two parts of lower body by integrated type simultaneously, can reduce the use of metallic material like this, save cost.

Claims

1. one kind big flow throttle valve, mainly comprise valve body, valve pocket, valve rod and valve rod base etc., it is characterized in that: the mangetic core assembly valve body center hole of packing into from the top of valve body, and with special tool with its riveting jail, the valve component that valve body and mangetic core assembly are formed is pressed into the valve pocket base apertures from the valve pocket bottom, valve rod screws in the valve rod base screw, and valve rod base is pressed into the valve pocket upper hole from top, and regulating wheel and locking wheel are installed on the valve rod.
