Therefore, need to design new back pressure valve opening device, thus the effective problem solving its unlatching difficulty.
Model utility content
The purpose of this utility model is to provide a kind of Novel back pressure valve automatic flat opening device, bypass valve can water-filling concora crush automatically before valve opening for this opening device, after concora crush, back pressure valve can realize non-resistance unlatching, the safety and reliability of assure feed water system and equipment.
In order to realize above-mentioned technical characteristics, the purpose of this utility model is achieved in that a kind of Novel back pressure valve automatic flat opening device, it comprises upstream main pipeline, main branch road and collateral road is provided with after the main pipeline of upstream, main branch road is provided with back pressure valve to be opened, a differential pressure controller in parallel on the upstream and downstream pipeline of back pressure valve to be opened, back pressure valve outlet to be opened is connected with a decompression branch road; Described collateral road is provided with piloted reducer, after piloted reducer, is connected with No. two decompression branch roads, after a decompression branch road and No. two decompression branch roads, be connected with downstream main pipeline.
Described piloted reducer is electromagnetic type type pilot reduction valve.
The control voltage of described electromagnetic type type pilot reduction valve is 24V.
Described electromagnetic type type pilot reduction valve adopts telecontrol.
Described back pressure valve to be opened is mortor operated valve.
Described differential pressure controller can detect the pressure difference of back pressure valve both sides to be opened, automatically can control the keying of back pressure valve to be opened when pressure difference reaches predetermined value.
The utility model has following beneficial effect:
At upstream and downstream branch circuit parallel connection differential pressure controller of original back pressure valve to be opened, a collateral road in parallel on main branch road simultaneously, a piloted reducer is installed on collateral road, piloted reducer is in closed condition under normal circumstances, now back pressure valve to be opened bears the pressure of increasing, when needs carry out unlatching operation to back pressure valve to be opened, just there is certain difficulty, therefore, telecontrol piloted reducer can be passed through, long-rangely send open command, now the solenoid valve of piloted reducer is opened, according to the performance characteristic of Self-operated pressure reducing valve, reduction valve is opened automatically, thus make the high pressure water of upstream main pipeline flow to No. two decompression branch roads by piloted reducer, make the also corresponding increase of the hydraulic pressure of a decompression branch road, when the circuit pressure difference of main branch road and a decompression branch road is more or less the same, differential pressure controller just detects pressure difference value, thus differential pressure controller output signal makes the closed electromagnetic valve of piloted reducer, and then piloted reducer is closed, the mortor operated valve of back pressure valve to be opened obtains automatically opening after differential pressure controller exports concora crush signal simultaneously.The non-resistance finally realizing back pressure valve to be opened is opened.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the utility model overall structure figure.
In figure: upstream main pipeline 1, main branch road 2, collateral road 3, back pressure valve to be opened 4, differential pressure controller 5, piloted reducer 6, No. two decompression branch roads 7, decompression branch road 8, a downstream main pipeline 9.
Embodiment
Below in conjunction with accompanying drawing, mode of execution of the present utility model is described further.
As shown in Figure 1, a kind of Novel back pressure valve automatic flat opening device, it comprises upstream main pipeline 1, main branch road 2 and collateral road 3 is provided with after upstream main pipeline 1, main branch road 2 is provided with back pressure valve 4 to be opened, a differential pressure controller 5 in parallel on the upstream and downstream pipeline of back pressure valve 4 to be opened, back pressure valve 4 outlet to be opened is connected with a decompression branch road 8; Described collateral road 3 is provided with piloted reducer 6, after being connected with No. two decompression branch roads 7, decompression branch road 8 and No. two decompression branch roads 7 after piloted reducer 6, is connected with downstream main pipeline 9.
Further, described piloted reducer 6 is electromagnetic type type pilot reduction valve.By electromagnetic type type pilot reduction valve, facilitate the unlatching of reduction valve, adopt electromagnetic mode to control simultaneously, remote detection operation can be facilitated, ensure that the Security of operation, improve the convenience of operation.
Further, the control voltage of described electromagnetic type type pilot reduction valve is 24V.Low voltage control is adopted to ensure that the Security of control.
Further, described electromagnetic type type pilot reduction valve adopts telecontrol.The convenient degree of control is improve by telecontrol.
