Abstract
The present invention relates to a release valve controlled by pressure to open and close, which is composed of a valve body, a valve rod, a sealing gasket, a spring, a spacing rod and a proximity switch. The valve is an important component in a drainage system of a water spray device. When the water spray device starts spraying water, an emptying valve is automatically closed under the action of water pressure, and the normal water spray of the water spray device is not influenced. When the water spray device stops spraying water, the emptying valve is automatically opened under the action of the spring arranged inside, and the remaining water in a spray pipe can discharge from the emptying valve. A mechanical switch of the valve is linked with the electronic proximity switch, and switch signals can be transferred to a main control room by the proximity switch.
Description
Technical field
The present invention relates to a kind of emptying valve, belong to emptying special valve field by pressure control switch.
Coal pollutes environment on every side in order to prevent coal dust in stacking, storage and transport process, and it is dustproof to adopt water spray system that coal is sprayed water, and is one of widely used method of many coal storage and transport units.
Present existing various water spray systems owing to there is not the emptying system, close spray equipment after, still have Yu Shui in the shower of spray equipment, in winter,, can damage spray equipment, so can not use in the north winter because intraluminal surplus water can freeze.Had the part spray equipment to improve afterwards, and adopt solenoid valve and ball one-way valve to carry out the surplus water of emptying, but the fault of solenoid valve was many, cost is higher; The ball one-way valve can not transmit signal to master control room, and working life is short.
Summary of the invention
Purpose of the present invention is for a kind of emptying valve that is carried out control switch by pressure is provided.After spray equipment was installed and used this emptying valve, when spray equipment quit work, emptying valve can be automatically discharged the intraluminal surplus water of spray equipment, but made the spray equipment also purpose of proper functioning in the winter time to reach.
In order to achieve the above object, the present invention is achieved through the following technical solutions.
A kind of emptying valve (seeing accompanying drawing) by pressure control switch, it mainly includes valve body 1, valve rod 2, spring 4, position-limited lever 5, wherein: a sealing gasket 3 is installed in the setting of the bottom of valve rod 2, on valve rod 2, be provided with a spring 4 is installed, position-limited lever 5 is provided with the lower end that is installed in valve rod 2, and the lower side setting of valve body 1 is equipped with an integrated inductor formula near switch 6.
Fit dimension between described valve body 1 and the valve rod 2 is 12 millimeters of ￠.
Emptying valve of the present invention is a kind of mechanical valve and the emptying valve that is integrated near switch.Valve body 1 outer upper ends and lower end are connected with upper and lower emptying pipe by the one-inch taper pipe thread, valve rod 2 brass manufacturing, and sealing gasket 3 usefulness polyamine fat are made, and position-limited lever 5, spring 4 usefulness stainless steel materials are made; Near switch 6, adopt current state-of-the-art novel integrated inductor formula near switch.
When spray equipment began to spray water, under the effect of water pressure, the valve rod 2 in the middle of the valve body 1 was depressed, and simultaneously, the spring 4 that is contained on the valve rod 2 also is depressed.When hydraulic pressure during greater than 3 kilograms, on the boss of boss on the valve rod 2 in sealing gasket 3 is pressed on valve body 1, this moment this valve closing, simultaneously, the position-limited lever 5 that is contained on the valve rod 2 is also moved down, when position-limited lever 5 moves down into induction zone near switch 6 because valve rod 2 moves down, at this moment, be switched near switch 6, circuit can be delivered to the control room immediately with signal, and the staff promptly knows the working state of spray equipment; When spray equipment stops to spray water, at this moment, the shower remaining water in the inside is not owing to there has been pressure, valve rod 2 is boosted under the active force of spring 4 in the emptying valve, the remaining a part of water in shower the inside can release through the center hole of valve rod 2 and the aperture on the position-limited lever 5 naturally by the aperture of 3.5 millimeters of 4 horizontal on the valve rod 2 ￠.Simultaneously, because valve rod 2 is boosted under the effect of spring 4, position-limited lever 5 can and then move up, and leaves the induction zone near switch 6, and at this moment, the circuit that taps into switch 6 disconnects, and the staff in the master control room can receive signal.
Major technique feature of the present invention and beneficial effect are:
1, emptying valve of the present invention can excrete the surplus water in the spray equipment automatically, thereby prevents that winter is freezing with spray equipment;
2, the spring 4 of this valve is to adopt stainless steel material to make, and corrosion-resistant, the life-span is long; Sealing gasket adopts polyamine fat made, good seal performance;
3, emptying valve of the present invention adopts the inter-linked controlling method that mechanical switch combines with electronic proximity switch, signal can be delivered to master control room fast, is fit to carry out remote monitoring.
4, valve body 1 of the present invention is to adopt the cylindrical mode that combines with the cooperation of valve rod 2, and it is more stable to move up and down, and reliable performance is difficult for breaking down, long service life, low cost of manufacture.

Embodiment
Embodiment as shown in drawings
After each parts installation in the emptying valve, and then emptying valve vertically is installed in the emptying system of spray equipment.When spray equipment began to spray water, under the effect of water pressure, the valve rod 2 in the middle of the valve body 1 was depressed, and simultaneously, the spring 4 that is contained on the valve rod 2 also is depressed.When hydraulic pressure during greater than 3 kilograms, on the boss of boss on the valve rod 2 in sealing gasket 3 is pressed on valve body 1, this moment this valve closing, simultaneously, the position-limited lever 5 that is contained on the valve rod 2 is also moved down, when position-limited lever 5 moves down into induction zone near switch 6 because valve rod 2 moves down, at this moment, be switched near switch 6, circuit can be delivered to master control room immediately with signal, and the staff promptly knows the working state of spray equipment.When spray equipment stops to spray water, at this moment, the shower remaining water in the inside is not owing to there has been pressure, valve rod 2 is boosted under the active force of spring 4 in the emptying valve, remaining a part of water can release through the center hole of valve rod 2 and the aperture on the position-limited lever 5 naturally by the aperture of 3.5 millimeters of 4 horizontal on the valve rod 2 ￠ in the shower.Simultaneously, because valve rod 2 is boosted under the effect of spring 4, position-limited lever 5 can and then move up, and leaves the induction zone near switch 6, and at this moment, near the circuit disconnection of switch 6, the staff in the master control room can receive signal.
