Abstract
The utility model discloses a bonnet limiting mechanism of a high-sealing aseptic split-body valve. The bonnet limiting mechanism of the high-sealing aseptic split-body valve comprises a bonnet and an assistant butterfly plate, wherein the bonnet limiting mechanism comprises a first limiting pin, a first returning spring, a first baffle plate, and a first stepped hole which is arranged on the bonnet; the first limiting pin is a stepped shaft which is matched with the first stepped hole; a small-diameter section of the first limiting pin passes through a small-diameter hole of the first stepped hole; the first baffle plate is fixedly installed on the first limiting pin; a first protruding pin head is arranged at the outer end of a large-diameter section of the first limiting pin; the first returning spring is sleeved on the small-diameter section of the first limiting pin; and two ends of the first returning spring are pressed against one side of the large-diameter section of the first limiting pin and a transitional wall of a large-diameter hole of the first stepped hole. The bonnet limiting mechanism of the high-sealing aseptic split-body valve has the advantage that the misoperation of the assistant butterfly plate before a driving valve and a driven valve are butted and fixed can be effectively prevented, so that sanitation of a medium is effectively ensured.
Description
Technical field
The utility model relates to the aseptic split-body valve of a kind of high sealing, specifically is meant a kind of auxiliary valve body position-limit mechanism.
Background technique
Often need transport in industries such as pharmacy or food each fluid in the upper reaches or downstream.The main butterfly valve that adopts is transported control in the existing technology, and its workflow generally is butterfly valve to cut out be installed in then on tank body or the pipeline, and then the opposite side of this butterfly valve docks with other tank bodies and pipeline, carries out the transfer of fluid opening butterfly valve then.The butterfly valve of this mode is applied to the transhipment of fluid, fool proof mechanism generally all is not set, therefore; When the two ends of butterfly valve do not have butterfly valve to be opened and misoperation occurs fully to connecting, will cause fluid to receive severe contamination; Thereby cause fluid to be scrapped, bring great economic loss.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming and defect that existing technology exists, and a kind of auxiliary valve body position-limit mechanism that can effectively prevent the aseptic split-body valve of high sealing of misoperation is provided.
For realizing above-mentioned purpose; The new technological scheme of this use is to include auxiliary valve body and secondary dish plate; Described auxiliary valve body position-limit mechanism includes first position limit pin, first Returnning spring and first baffle plate; Also include first shoulder hole that is arranged on the auxiliary valve body, described first position limit pin is and the suitable multidiameter shaft of first shoulder hole that the thin diameter section of said first position limit pin passes the hole, thin footpath of first shoulder hole; And fixed installation first baffle plate on it; The outer end of the wide section of described first position limit pin is provided with the first pin head of convexity, and the sidepiece of described secondary dish plate is provided with and this first pin chimeric first spacing shrinkage pool, and described first Returnning spring is set on the thin diameter section of first position limit pin; And the two ends of this first Returnning spring are connected to respectively on the transition wall in particle size hole of a side and first shoulder hole of wide section of first position limit pin, and described first baffle plate includes the portion of exposing outside the periphery that at least one place exposes to auxiliary valve body.Through the auxiliary valve body position-limit mechanism of this setting, butt joint is not fixedly the time in aggressive valve and passive valve, and first position limit pin carries out spacing to secondary dish plate under the effect of first Returnning spring; Prevent that it from rotating because of the unexpected open auxiliary dish of misoperation plate; Thereby ensured the safe and sanitary of fluid, and when aggressive valve with after passive valve is docked, the portion of exposing of ejection part pushing tow first baffle plate through aggressive valve; Thereby removed the rotary spacing of first position limit pin to secondary dish plate, this moment all can be through operation open auxiliary dish plate.
Further being provided with is that described first Returnning spring is a coil tension spring.
The utility model has the advantages that can effectively prevent aggressive valve and passive valve not butt joint fixing before, and the situation that secondary dish plate carries out misoperation is taken place, effectively ensured the health of transhipment medium.
Below in conjunction with Figure of description and embodiment the utility model is done further introduction.
Description of drawings
Fig. 1 the utility model embodiment is applied to the structural representation on the passive valve.
Embodiment
The embodiment of the utility model as shown in Figure 1; Include the auxiliary valve body 21 and secondary dish plate 22 that are arranged on the passive valve; The described auxiliary valve body 21 of present embodiment is provided with the auxiliary valve body position-limit mechanism; This auxiliary valve body position-limit mechanism includes first position limit pin 23, first Returnning spring 24 and first baffle plate 25; Described auxiliary valve body 21 is provided with first shoulder hole 211 of perforation, and described first position limit pin 23 is and the suitable multidiameter shaft of first shoulder hole 211 that the thin diameter section of said first position limit pin 23 passes the hole, thin footpath of first shoulder hole 211; And fixed installation first baffle plate 25 on it; The outer end of the wide section of described first position limit pin 23 is provided with the first protruding pin 231, and the sidepiece of described secondary dish plate 22 is provided with and these first pin, 231 chimeric first spacing shrinkage pools 221, and described first Returnning spring 24 is set on the thin diameter section of first position limit pin 23; And the two ends of this first Returnning spring 24 are connected to respectively on the transition wall 2111 in particle size hole of a side 232 and first shoulder hole 211 of wide section of first position limit pin 23; Described first baffle plate 25 includes the portion of exposing 251 outside the periphery that at least one place exposes to auxiliary valve body 21, in addition, and when practical application; Only need be provided with the ejection part that cooperates with the portion of exposing 251 ejections of first baffle plate in the aggressive valve of split-body valve, the running length of this ejection part ejection first baffle plate is sold 231 length greater than first.Thereby when making the butt joint of passive valve and aggressive valve, the ejection of this ejection part can be removed the spacing of 23 pairs of secondary dish plates 22 of first position limit pin.This ejection part of present embodiment is for rotating the position of corresponding first baffle plate 25 on the pressing plate.
The foregoing description is to the specific descriptions of the utility model; Only be used for the utility model is further specified; Can not be interpreted as the qualification to the utility model protection domain, the technician of related domain according to the content of above-mentioned model utility the utility model is made some nonessential improvement and adjustment all falls within the protection domain of the utility model.
