Abstract

The utility model discloses a manual forced opening check valve, which comprises a valve body, a retaining ring is fixedly connected above the inner part of the valve body, a fixed ring is fixedly connected with the bottom end of the retaining ring, through holes are respectively arranged at the middle parts of the fixed ring and the retaining ring, a valve core is matched with the inner part of the through hole in an inserting way, and a spring is butted between the valve core and the fixed ring; the inside bottom of valve body rotates and is connected with the axostylus axostyle, the bottom middle part fixedly connected with rotary cam of axostylus axostyle. Through the structure, the shaft lever, the handle and the valve core are arranged, so that the problems that when materials are high in viscosity, the valve core of the check valve is easy to suck on the valve body and the check valve is difficult to open automatically are effectively solved through the valve core; when the material has the particulate matter, the check valve case blocks easily, causes the unable automatic problem of opening of check valve.

Description

Manual forced opening check valve

Technical Field

The utility model relates to a manual check valve technical field, in particular to manual compulsory check valve of opening.

Background

The check valve is a valve with a circular valve clack and acts by self weight and medium pressure to block the medium from flowing backwards.

Most of check valves in the prior art are in an electric control opening and closing state, and when materials in a pipeline are high in viscosity during use, a valve core of the check valve is easy to be absorbed on a valve body, and the check valve is difficult to automatically open; the normal open mode can't be reached, and when the material in the pipeline had the particulate matter simultaneously, the particulate matter can get into the check valve case inside to block easily, cause the unable automation of check valve to open, still need further to solve to this problem perfect.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve one of the technical problem that exists among the prior art at least, provide a manual forced open check valve, effectively solved the material through the case when high viscosity, the check valve case is inhaled on the valve body easily, and the check valve is automatic to be opened the difficulty.

To achieve the above object, there is provided a manual forced opening check valve including: the valve comprises a valve body, wherein a check ring is fixedly connected to the upper part inside the valve body, the bottom end of the check ring is fixedly connected with a fixing ring, through holes are formed in the middle parts of the fixing ring and the check ring, a valve core is inserted and matched in the through holes, and a spring is abutted between the valve core and the fixing ring;

the inside bottom of valve body rotates and is connected with the axostylus axostyle, the bottom middle part fixedly connected with rotary cam of axostylus axostyle.

According to the manual forced opening check valve, one end of the shaft rod is fixedly connected with a handle.

According to the manual forced opening check valve, the valve core is in a reverse cross shape.

According to the manual forced opening check valve, the outer ring of the bottom of the valve core is fixedly connected with the sealing ring.

Has the beneficial effects that:

compared with the prior art, the utility model is provided with the shaft lever, the handle and the valve core, and effectively solves the problems that when the material has high viscosity, the valve core of the check valve is easy to be absorbed on the valve body, and the check valve is difficult to be automatically opened; when the material has the particulate matter, the check valve case blocks easily, causes the unable automatic problem of opening of check valve.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

Drawings

The present invention will be further described with reference to the accompanying drawings and examples;

FIG. 1 is a sectional front view of the check valve of the present invention;

fig. 2 is a front view structural diagram of the manual forced opening check valve of the present invention.

Illustration of the drawings:

1. a valve body; 2. a retainer ring; 3. a fixed ring; 4. a spring; 5. a valve core; 6. a seal ring; 7. a shaft lever; 8. a rotating cam; 9. a handle.

Detailed Description

This section will describe in detail the embodiments of the present invention, the preferred embodiments of which are shown in the attached drawings, which are used to supplement the description of the text part of the specification with figures, so that one can visually and vividly understand each technical feature and the whole technical solution of the present invention, but it cannot be understood as a limitation to the scope of the present invention.

Referring to fig. 1-2, an embodiment of the present invention provides a manual forced opening check valve, which includes: the check valve comprises a valve body 1, a check ring 2 is fixedly connected to the upper portion inside the valve body 1, the check ring 2 is used for limiting and blocking, an opening is formed in the outer ring of the check ring 2, material circulation is facilitated, a fixing ring 3 is fixedly connected to the bottom end of the check ring 2, sealing effect is achieved through the fixing ring 3, through holes are formed in the middle portions of the fixing ring 3 and the check ring 2, a valve core 5 is matched with the inside of each through hole in an inserted mode, opening and closing operation of the check valve is achieved through the valve core 5, a spring 4 is abutted between the valve core 5 and the fixing ring 3 and elastically supported through the spring 4, elastic support closing is facilitated, back pressure opening operation is achieved, the valve core 5 is in a reverse cross shape and is jacked up through a rotating cam 8, the valve core 5 of the check valve core 5 slides upwards and operates in an opening state, a sealing ring 6 is fixedly connected to the outer ring at the bottom of the valve core 5, and smaller material circulation is prevented through the sealing ring 6;

the inside bottom of valve body 1 rotates and is connected with axostylus axostyle 7, through the rotation of axostylus axostyle 7, is convenient for to opening and closed regulation operation, and the bottom middle part fixedly connected with rotating cam 8 of axostylus axostyle 7 can provide opening and closure state through rotating cam 8 jack-up and reverse, and the one end fixedly connected with handle 9 of axostylus axostyle 7 can carry out manual control operation by force through handle 9.

The working principle is as follows: when in use, the handle 9 rotates to enable the rotating cam 8 to jack the valve core 5 upwards, and the manual full-open state is shown in figure 2. The valve core 5 can be lifted up to enable the materials to flow, so that the situation that the valve core 5 of the check valve is easily sucked on the valve body 1 and the check valve is difficult to open automatically when the high-viscosity materials flow through is effectively prevented; when the material has the particulate matter, check valve case 5 blocks easily, causes the unable automatic problem of opening of check valve.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
