Abstract
The utility model provides an inverted valve. The technical proposal is that the utility model consists of a shell body and a valve body arranged inside the shell body, and is characterized in that the shell body consists of an upper cylindrical shell body and a matched lower cylindrical shell body. The lower shell body is provided with a round smooth inlet, and the diameter of the inlet is smaller than the diameter of the valve body. The upper shell body is provided with at least one retainer and one outlet, and the retainer is arranged at the lower part of the outlet. A spherical valve body is arranged inside a valve cavity formed by the upper shell body and the lower shell body, and the diameter of the spherical valve body should be smaller than the big inside diameter and larger than the half of the big inside diameter of the shell body. The inverted valve is formed by installing an upper shell body together with a lower shell body and arranging a spherical valve body inside. Compared with the prior inverted valve, the inverted valve has the advantages of flexibly-switched valve body, corrosion resistance, high-temperature resistance, high-pressure resistance, long service life, simple structure and low manufacturing cost. The check valve is widely applicable to liquid transmission pipelines of various types.
Description
Affiliated technical field
The utility model relates to a kind of check valve.
Background technique
Existing check valve is many to be made up of shell and Movable valve, exists the easy to leak phenomenon, is weak aspect acidproof, alkaline-resisting in addition more, and what have exists shortcoming such as cost height.
Summary of the invention
The purpose of this utility model solves above-mentioned shortcoming exactly, and a kind of use simple in structure, acidproof, alkaline-resisting, high temperature resistant, flexible, cheap check valve are provided.
Technical solution of the present utility model is made up of housing and the valve body that is contained in the housing, it is characterized in that: housing comprises a cylinder upper shell and the cylinder lower shell body that cooperates with it, lower shell body has a smooth circular import, the diameter of import is less than the diameter of valve body, upper shell has at least shelves to mix, also has an outlet, shelves are mixed below outlet, in the valve pocket that upper shell and lower shell body are formed a spherical valve body is housed, the diameter of spherical valve body should be less than the housing large diameter, greater than 1/2 housing large diameter.
Above-mentioned said spherical valve body is made with metal or rubber or plastics, also can be that the metallic material outside comprises one deck rubber or plastic article, metallic material can be selected stainless steel, copper or cast iron, plastics can be polyethylene, polypropylene or engineering plastics, and spherical valve body can be made hollow or solid.
Connection part at upper shell and lower shell body should have seal ring, and seal ring can be rubber or plastics.
The weight of spherical valve body should be greater than the buoyancy of institute's flow liquid body to spherical valve body.
Spherical check valve of the present utility model can be widely used in the environment such as acid, alkali, high temperature, high pressure.
Spherical check valve of the present utility model compared with prior art has advantages such as the life-span is long, simple in structure, cheap.
Description of drawings
Fig. 1 is the structural representation of the spherical check valve of the utility model
Wherein 1, upper shell 2, lower shell body 3, seal ring 4, spherical valve body 5, shelves are mixed 6, portal 7, are entered the hole
Embodiment
Working principle of the present utility model is: this spherical check valve should vertically be installed, lower shell body (2) has import (7), upper shell (1) has outlet (6), when liquid enters check valve, valve body (4) makes progress under the effect of liquid top power, since above have shelves to mix (5) to block valve body (4) and can not continue upwards, around the valve body (4) and between housing (1) (2) cross wall space is arranged, liquid passes through; Otherwise valve body (4) water intake below housing blocks liquid return, plays non-return effect; Why the inlet of lower shell body is made smooth circular formula in order to increase its seal, in order to increase the use of can connecting of non-return this valve of property.
Compare with existing non-return valve, it is flexible that this non-return valve has valve body switch, corrosion-resistant, The advantage such as high temperature high voltage resistant, life-span are long, simple in structure, cheap. This non-return valve can be wide General for various liquid conducting pipes.
Claims (4)
1. check valve, form by housing and the valve body that is contained in the housing, it is characterized in that: housing comprises a cylinder upper shell (1) and the cylinder lower shell body (2) that cooperates with it, lower shell body (2) has a smooth circular import (7), the bore of import (7) is less than the bore of valve body, upper shell (1) has at least shelves to mix (5), also has an outlet (6), shelves are mixed (5) below in outlet (6), in the valve pocket that upper shell (1) and lower shell body (2) are formed a spherical valve body (4) is housed, the diameter of spherical valve body (4) should be less than the housing major diameter, greater than 1/2 housing major diameter.
2. check valve according to claim 1, it is characterized in that described spherical valve body (4) makes with metal or rubber or plastics, also can be that the metallic material outside comprises one deck rubber or plastic article, metallic material can be selected stainless steel, copper or cast iron, plastics can be polyethylene, polypropylene or engineering plastics, and spherical valve body can be made hollow or solid.
3. check valve according to claim 1 is characterized in that the described upper shell (1) and the connection part of lower shell body (2) should have seal ring (3), and seal ring can be rubber or plastics.
4. check valve according to claim 1 and 2 is characterized in that the weight of described spherical valve body (4) should be greater than the buoyancy of institute's flow liquid body to spherical valve body.
