Abstract

The utility model discloses an adjustable valve for two-phase mixed medium, comprising a valve body (1), a left valve handle (2) and a right valve handle (6)which are arranged in a concentric mode, a valve core (5) arranged in the flow passage of the valve body, and a sealing valve base (3) which is arranged on one side of the flow passage of the valve body to cooperate with the sealing surface of the valve core (5) to form a sealing pair. The utility model is characterized in that the valve core (5) is the two-valve split hemi-spherical structure, and one end of a valve core (7) is fixedly connected with the left valve handle (2) while the other end is movably connected with the right valve handle (6); one end of the other valve core (8) is fixedly connected with the right valve handle (6) while the other end is movably connected with the left valve handle (2). The utility model not only has the advantage of portable and labor-saving opening, but also enables the conveyed medium to pass through the flow passage of the valve body without any countercheck, which can effectively avoid turbulent current; the position of the opened valve core can protect the inner wall of the valve body.

Description

Two-phase Mixed Flow Medium Using For Regulating Valve

(1) technical field

The utility model relates to a kind of valve, relates to a kind of Two-phase Mixed Flow Medium Using For Regulating Valve specifically.

(2) background technique

In " gaseous state-solid-state " or " liquid-solid-state " two-phase mixed flow medium transport pipeline, generally all need be provided for regulating the modulating valve of flow, do not put goods on the market owing to up to the present still there is special-purpose modulating valve, therefore the general alternatives that adopt class valve effect flow control valves such as gate valve, stop valve or butterfly valve in the two-phase mixed flow medium transport pipeline of prior art more.And above-mentioned alternative is subjected to the restriction of himself structure, in MEDIA FLOW during,, cause sealing pair and valve interior wall to be subjected to washing away in various degree because variation in various degree can take place for direction of flow and pressure through sealing pair, to such an extent as to the concentrated wear phenomenon often takes place, can cause scrapping of valve when serious.Occur because of the accumulation of fed sheet of a media in valve pocket, the obstruction accident that the precipitation fouling causes in some medium transport occasion also regular meeting, cause valve invalidation and have to be removed replacing.

(3) summary of the invention

The purpose of this utility model provides a kind of scientific and reasonable for structure, two semiglobes that cross section of fluid channel can be regulated arbitrarily, twin shaft to regulate just at existing deficiency in the above-mentioned prior art opposite opened Two-phase Mixed Flow Medium Using For Regulating Valve.

The purpose of this utility model can realize by following technique measures:

Two-phase Mixed Flow Medium Using For Regulating Valve of the present utility model comprises that the two-part combinaing valve body be made up of main valve body and auxiliary valve body, the left and right valve rod by concentric setting are installed in the spool in the main valve body runner; Described spool is two lobe opposite opened hemispherical dome structures; Wherein an end of a clack valve core combines with left valve rod in fixedly connected mode, the other end combines with right valve rod in mode movingly, one end of another clack valve core combines with right valve rod in fixedly connected mode, and the other end combines with left valve rod in mode movingly.

The seal valve seat that forms sealing pair of matching with the ball sealer cambered surface of spool in the utility model is fitted between main valve body and the auxiliary valve body also; The ball sealer cambered surface of described spool and the sealing surface of seal valve seat all adopt the welding manner built-up welding that wear-resisting, the alloy-layer of anti-the scratch are arranged.

Because spool of the present utility model is the two hemisphere that can regulate its open degree arbitrarily, the opposite opened structure that twin shaft is regulated, this just makes the utility model not only have rapid, the light labour-saving of unlatching advantage, main is when spool is in opening state, two clack valve cores are respectively around the both sides of two valve rod switching valve intracoelomic cavities, make that being transferred medium can pass through valve flowing channel under the condition that has no to stop, therefore can effectively stop the generation of turbulent flow, and the big more effect of open degree is obvious more; In addition, be in same plane, therefrom to reduce gradually around the mind-set owing to be transferred the flow velocity of medium, this just feasible scouring force near the valve interior wall place can reduce significantly, and the effect of protection valve interior wall also can be played in the spool present position after the unlatching.And the sealing surface of the sealing sphere of spool and seal valve seat all adopts the welding manner built-up welding to have technical measures wear-resisting, the alloy-layer of anti-the scratch that the wear resistance of valve and working life are greatly improved.And described seal valve seat is fitted between main valve body and the auxiliary valve body, and this DESIGNED FEATURE can be replacing, the maintenance of seal valve seat and provides convenience.

Fig. 1 is a plan view of the present utility model.

Fig. 2 is the A-A sectional view of Fig. 1.

(5) embodiment

The utility model is further described below with reference to embodiment's (accompanying drawing):

Two-phase Mixed Flow Medium Using For Regulating Valve of the present utility model comprises that the two-part combinaing valve body be made up of main valve body 1 and auxiliary valve body 4, the left and right valve rod 2,6 by concentric setting are installed in the spool 5 in the main valve body runner; Described spool 5 is two lobe opposite opened hemispherical dome structures; Wherein an end of a clack valve core 8 combines with left valve rod 2 in fixedly connected mode, the other end combines with right valve rod 6 in mode movingly, one end of another clack valve core 7 combines with right valve rod 6 in fixedly connected mode, and the other end combines with left valve rod 2 in mode movingly; The seal valve seat 3 that forms sealing pair of matching with the ball sealer cambered surface of spool 5 is fitted between main valve body 1 and the auxiliary valve body 4 also; The ball sealer cambered surface of spool 5 and seal valve seat 3 sealing surfaces all adopt the welding manner built-up welding that wear-resisting, the alloy-layer of anti-the scratch are arranged.

Working principle of the present utility model is as follows:

Figure 2 shows that closed condition of the present utility model, when needs are opened, drive unit drives left and right valve rod (2) (6) simultaneously by linking mechanism and rotates, and then drive spool (7) respectively and spool (8) (is seen shown in Figure 2 to two sideway swivels by left and right valve rod (2) (6), dotted line is depicted as the position after spool is opened among the figure, the dotted line position of the topmost part is the position of spool when opening 90 °), until rotating to full open position, form the overall diameter passage.Except that full cut-off and fully open position, any one enable possition all can be used as the adjusting passage of medium.Realize the purpose of Flow-rate adjustment by the size of regulating Flow area.
