CN2319454Y - Water level control valve of grand building storage water tank - Google Patents

Abstract

The utility model discloses a water level control valve of a high-rise water storing tank. The self-adaptive ability of the valve port close force is increased with the increase of the water net pressure. The utility model comprises a main valve core control mechanism, a pilot valve control mechanism 8 and a water plugging mechanism. A water passing cavity and a control cavity are formed by the division by a rubber diaphragm arranged between a valve body and a valve cap. No relative friction is created during the opening or closing movement of the valve, which not only reduces the clearance leakage and saves energy and water, but also prolongs the service life. Besides, when the diaphragm is fatigued or is damaged, a hand lever head in the water plugging mechanism can be screwed down by hand to press a valve plug to close a valve port. The utility model is free from the limitation of water pressure and can be used in various occasions.

Description

High building water storage box altitude valve

The utility model relates to a kind of water level valve, is used for the water level control in water tank or pond.

Existing cistern water level control valve is five, the piston valve of sixties exploitation, its performance long-term existence is not closed completely, and promptly leaks, the spilling water phenomenon, because its sealing force is to produce by buoyancy moment, along with water pressure raises, itself does not have adaptive ability valve, has the congenital factor of leaking, and adds the restriction that is sealed, close and open at piston and produce friction in the process of valve port, the formation wearing clearance leaks, and has influenced application life, has also caused the waste of water resource.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, provides a kind of and raises with pressure of water network, and valve port is closed the altitude valve that force adaptive increases.

For achieving the above object, the utility model is realized by following measure: the centre between valve gap and valve body is equipped with main valve plug mechanism, is used for that valve port is closed and pressure adaptive is regulated; The pilot valve controlling organization is installed on valve body, is used for the upper cavity pressure of control valve, pressure release is regulated and is closed and boosts; Directly over main valve plug mechanism, the top of valve gap is equipped with water blockoff mechanism, make urgent artificial water blockoff and use.

Advantage of the present utility model is:

1. this control valve does not have friction relatively in the motion that opens and closes, and has not only reduced clearance leakage, energy-conservation, water saving, and prolonged application life greatly.

2. this control valve is provided with safe and reliable water blockoff mechanism, and when the diaphragm fatigue damage, valve plug is pushed down in artificial hand-tight make-up handle top, makes valve port close.

3. pilot valve is arranged on the valve body, makes control water level move down, so that valve body does not contact the water surface, the minimizing water pollution.

4. be not subjected to the restriction of water pressure, can be used on multiple occasion.

Fig. 2 partly cuts open figure for the side-looking of Fig. 1 embodiment.

Fig. 3 is the structural representation of fly rod, ball float and gravity block in the utility model.

Fig. 4 is the vertical view of Fig. 1 embodiment.

The utility model is described in further detail below in conjunction with accompanying drawing.

By shown in Figure 1, directly over main valve plug mechanism, the top of valve gap 8 is equipped with water blockoff mechanism.The structure of this mechanism is, bullet position plug screw 6 is fixedly connected with valve gap 8, the mode that can adopt the end face inwall with valve gap 8 to be fixedly connected with screw thread, between bullet position plug screw 6 and valve gap 8 end faces, combined seal ring 5 can be housed, spacing spiral shell head 2 is housed on bullet position plug screw 6, handle bar 1 is positioned at the center of bullet position plug screw 6, connects for screw thread is movable between its lower end and the bullet position plug screw 6, on handle bar 1 O RunddichtringO 3 and y can be housed _xRunddichtringO 4 is to guarantee place, top leakproof.

Have water inlet and delivery port on valve body 18, the centre between valve gap 8 and valve body 18 is equipped with main valve plug mechanism.The structure of this mechanism is, is disposed with diaphragm seal 15, valve plug 17, separate space diaphragm 11 and pressuring film plate 12 on spool 16, fixed by clamp nut 13.Between clamp nut 13 and spool 16, stop screw 14 can be housed.Separate space diaphragm 11 places between valve gap 8 and the valve body 18, and the three is for being fixedly connected, and available bolt is fixed, and divides the chamber by separate space diaphragm 11 barrier films, forms water flowing chamber I and control chamber III.In order to prevent that the waterpower static pressure from making diaphragm 11 elastic deformations cause concussion and valve opening, causing vibrations when closing, and is equipped with lining ring 10 between separate space diaphragm 11, valve body 18 and valve plug 17.Between pressuring film plate 12 and bullet position plug screw 6, be connected to back-moving spring 7, close power with the precompressed that forms main valve plug.Thimble 9 is positioned at the center of handle bar 1 and spool 16, is fixedly connected with handle bar 1, and forms annular damping hole II between the spool 16.Thimble 9 is used for preventing the obstruction of damping hole and prevents diaphragm vibration and play the guiding role.

By shown in Figure 2, the pilot valve controlling organization is installed on valve body 18.The structure of this mechanism is, the lower end of guide's spool 20 is connected to guide's end socket 21, and guide's end socket 21 is a conehead, be preferably 58 degree, and valve port seat with matching is 60 degree, forms linear sealing, and sealing is reliable.Open and close on the spool 22 and be with sealing ring 24, and between the valve body 18 stop screw 23 can be housed, its end and buoyancy bar 26 are fixedly connected, can adopt screw thread to link, the other end contacts with guide's spool 20, between buoyancy bar 26 and ball float 29 gravity block 28 is housed, and is fixed with nut 27, opening and closing spool 22 can be stirred on guide's spool 20 and be moved by buoyancy bar 26 driven rotary.Formerly be connected to guide's spring 19 between guide valve core 20 and the valve gap 8, fall the position accurately in order to control guide spool.Formerly have the pod apertures VI on the guide valve core 20, be preferably two, communicate each other with the pod apertures VII that has on pod apertures V that has on the valve gap 8 and the valve body 18.Cone blocking 25 is used for the deblocking technology hole.

When water enters water tank by valve port, water level is risen, the buoyancy bar rotate risings under the buoyancy of ball float, make to open valve and close core and change pusher dog and break away from guide's spool, then closes the poppet port VII under the effect of guided missile spring formerly of guide's spool, and the water route is controlled in shutoff.At this moment, main valve plug is close port under the effect of back-moving spring, water inlet is still intake, through the epicoele III that the damping hole II of main valve enters main valve, this moment, epicoele did not have water outlet, and pressure raises suitable with following cavity pressure then, because main valve epicoele compression area is greater than following cavity area, state with reinforcement under the effect of static pressure compresses valve port, turn-offs water outlet, and the power of closing increases with the pressure of water network rising.When drawdown, the ball float loss of buoyance, at this moment the buoyancy bar is becoming torque under the gravity under the effect of gravity block, so that drive opens and closes the spool rotation and stirs and move on guide's spool, the valve port VII is opened, and the water of epicoele arrives delivery port, the pressure release of main valve epicoele then through pod apertures V, VI, VII thereupon, at this moment the pressure of water inlet makes valve port open the water outlet of delivery port IV greater than upper cavity pressure so that wash main valve plug open.
