Abstract
The utility model provides a hydraulic valve plate prevents pendant system, includes hydraulic cylinder, YR2 overflow valve, D4 check valve, YR2 overflow valve and D4 check valve are parallelly connected to be installed on hydraulic cylinder's main oil circuit, the oil inlet of D4 check valve is connected with the oil inlet end of main oil circuit, and the oil-out of D4 check valve is connected with the time oil return end of main oil circuit. When the hydraulic oil cylinder works, when hydraulic oil enters the hydraulic oil cylinder from the main oil way, the hydraulic oil passes through the D4 one-way valve, but the YR2 overflow valve is not communicated, and the system is normally controlled; when the main oil way returns oil, the D4 one-way valve is not communicated, oil is returned through the YR2 overflow valve, the YR2 overflow valve can adjust the opening pressure according to the dead weight of the valve plate, and the dead weight of the valve plate can be adjusted to be larger than or equal to the dead weight of the valve plate, so that the valve plate is not hung under the condition of pressure loss of the system.
Description
Technical Field
The utility model relates to a pendant system is prevented to hydraulic valve plate.
Background
The valve is widely applied, such as a butterfly valve, a plug valve and the like, but the mode commonly adopted by each valve at present is mechanical locking, and the valve has the defects that the valve is easy to block due to long-time locking, cannot be put into use when self-protection is put into use, or the valve is closed due to failure of locking and misoperation, so that potential safety hazards are brought to production.
Because during normal production, the valve plate of valve is full-open, and the valve plate is in the high-order, but misoperation or system decompression, the valve plate then can the pendant close, leads to the occurence of failure.
SUMMERY OF THE UTILITY MODEL
The utility model discloses its aim at provides a pendant system is prevented to hydraulic pressure valve plate to solve the problem among the above-mentioned background art, overcome the shortcoming that current valve machinery locked the position, avoided leading to the valve plate pendant because of misoperation, the condition that the valve position was closed takes place, and does not influence the fast closing and the regulation of valve.
According to the technical scheme, the hydraulic valve plate anti-pendant system comprises a hydraulic oil cylinder, a YR2 overflow valve and a D4 one-way valve, wherein the YR2 overflow valve and the D4 one-way valve are installed on a main oil path of the hydraulic oil cylinder in parallel, an oil inlet of the D4 one-way valve is connected with an oil inlet end of the main oil path, and an oil outlet of the D4 one-way valve is connected with an oil return end of the main oil path.
Advantageous effects
Compared with the prior art, the utility model has the following advantages.
When the hydraulic oil enters the hydraulic oil cylinder from the main oil way, the hydraulic oil passes through the D4 one-way valve, the YR2 overflow valve is not communicated, and the system is normally controlled; when the main oil way returns oil, the D4 one-way valve is not communicated, oil is returned through the YR2 overflow valve, the YR2 overflow valve can adjust the opening pressure according to the dead weight of the valve plate, and the dead weight of the valve plate can be adjusted to be larger than or equal to the dead weight of the valve plate, so that the valve plate does not hang under the condition of pressure loss or misoperation of the system, and the hydraulic control system has the advantages of simple structure, safety and reliability.
Drawings
The present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be further described with reference to the following examples and accompanying drawings.
As shown in fig. 1, the hydraulic valve plate pendant prevention system comprises a hydraulic oil cylinder 1, a YR2 overflow valve 2 and a D4 check valve 3, wherein the YR2 overflow valve 2 and the D4 check valve 3 are installed on a main oil path 4 of the hydraulic oil cylinder 1 in parallel, an oil inlet of the D4 check valve 3 is connected with an oil inlet end of the main oil path 4, and an oil outlet of the D4 check valve 3 is connected with an oil return end of the main oil path 4.
The YR2 overflow valve can adjust the opening pressure according to the self weight of the valve plate
The utility model comprises a hydraulic oil cylinder 1, a YR2 overflow valve 2 and a D4 one-way valve 3, when the hydraulic oil enters the hydraulic oil cylinder 1 from a main oil way 4 during operation, the hydraulic oil enters all the way through the D4 one-way valve 3, the YR2 overflow valve 2 is not communicated all the way, and the system is normally controlled at the moment; when the main oil way 4 returns oil, the D4 one-way valve 3 is not communicated, the hydraulic pressure rises, hydraulic oil returns through the YR2 overflow valve 2, the YR2 overflow valve can adjust the opening pressure according to the dead weight of the valve plate, and the valve plate can not be hung under the condition of pressure loss or misoperation of a hydraulic system.
