CN201335206Y - Sanitation-grade pneumatic angle-type adjusting valve - Google Patents

Abstract

The utility model relates to a sanitation-grade pneumatic angle-type adjusting valve, comprising a valve body, a valve core, a valve pole, a valve cover and a pneumatic mechanism; the inlet of the valve body is vertical to the outlet thereof, the upper end surface of the valve core is fixedly connected with the lower end of the valve pole, the axis of the valve pole is in coincidence with the central line of an inlet channel of the valve body, a sealing disc is arranged between the valve body and the valve cover, a sealing ring is arranged between the valve pole and the valve cover, the sealing ring is pressed between the valve pole and the valve cover by the sealing disc, so as to lead the height of the inner cavity of the valve body to be equal to the diameter of the outlet channel, thereby eliminating the connecting dead angle among the valve body, the valve cover and the valve pole and having the advantages of easy cleaning and sterilization and being in accordance with the sanitary requirements of food and medicine production. The adjusting valve is suitable for medium channels in the production field such as pharmacy, organism, food, brewing, beverage and the like.

Description

The pneumatic angle type control valve of health level

Technical field

The utility model relates to a kind of valve, particularly about a kind of pneumatic control valve.The utility model is applicable to pharmacy, biology, food, brewage the regulating valve with production field medium pipelines such as beverages.

Background technique

At pharmacy, biology, food, brewage in the production process with industry such as beverage, the valve of its use is had easy cleaning, the easily requirement of sterilization.At present, the valve of domestic production generally is made up of valve body, spool, valve rod, valve gap, there is many cleanings dead angle in formed valve pocket between its valve body, valve gap, the valve rod, the cleaning of unfavorable valve pocket and sterilization, do not reach pharmacy, biology, food, brewage with industry product production processes such as beverage in hygienic requirements.

Summary of the invention

The purpose of this utility model is the shortcoming that exists at prior art, and the pneumatic angle type control valve of health level of a kind of valve pocket easy cleaning, easy sterilization is provided.

The technical solution of the utility model comprises valve body, spool, valve rod, valve gap and pneumatic mechanism, the valve body inlet/outlet meets at right angles, fixedly connected with the valve rod lower end in the spool upper-end surface, valve rod axis and valve body inlet passage central lines, mainly be between valve body and valve gap, to establish a seal disc, establish a seal ring between valve rod and the valve gap, described seal ring is press-fited between valve rod and valve gap by seal disc.

The utility model beneficial effect compared with prior art is between valve gap and valve body and valve rod seal disc and seal ring to be set respectively, make body cavity height and outlet conduit equal diameters, eliminated the connection dead angle between valve body, valve gap, the valve rod three, have advantages such as easy cleaning, easy sterilization, meet the hygienic requirements of food, pharmaceutical production.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

The pneumatic angle type control valve of health level as shown in Figure 1, comprise valve body 1, spool 2, valve rod 12, valve gap 5 and pneumatic mechanism, valve body 1 inlet/outlet meets at right angles, fixedly connected with valve rod 12 lower ends in spool 2 upper-end surfaces, valve rod 12 axis and valve body 1 inlet passage central lines, between valve body 1 and valve gap 5, establish a seal disc 3, establish a seal ring 4 between valve rod 12 and the valve gap 5, sealing ring 4 is press-fited between valve rod 12 and valve gap 5 by seal disc 3, and the valve pocket height that constitutes between seal disc 3 and the valve body 1 equates with valve body 1 pipe outlet.Valve body 1, spool 2, valve rod 12, valve gap 5, seal disc 3, seal ring 4 are stainless steel material, and valve body 1 internal surface adopts the electronics technique for grinding to handle.Pneumatic mechanism comprises diaphragm 9, spring 10 and push rod 7, push rod 7 is fixedly connected on the diaphragm 9, fixedly connected with valve rod 12 by opening nut 6 in its lower end, the upper end is one stroke bounding means 11 fixedly, restriction valve rod 12 lifting heights, fix a postive stop baffle 8 on the pneumatic mechanism housing below diaphragm 9, the position that restriction valve rod 12 descends.Valve body 1 is pounded card 13 with valve gap 5 by stainless steel and is tightly connected.
