The valve has the beneficial effects of novel concept, simple structure and easy operation, and can be widely applied in the piping gas industry.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of automatic control motor valve.
Background technique
As everyone knows, rock gas is big because of its calorific value, pollute advantage such as little enjoys the user to favor, and the user is more and more, and consumption is increasing, and the use of big flow gas meter comes generally more.Yet present big flow gas meter all is to adopt the mode of external valve to control, heavy inconvenience.Reliability is not high, and the cost of motor ball valve is high, causes heavy economic burden to the user, influences promoting the use of of gas meter.
Summary of the invention
The purpose of this utility model is exactly in order to remedy the deficiencies in the prior art, and a kind of automatic control motor valve of novel, simple in structure, cheap, safe in utilization, easy operating is provided.
To achieve these goals, the technological scheme of the automatic control motor valve that the utility model is related is such: a kind of automatic control motor valve, by retarder, valve body, valve port, sealing gasket, spool, screw rod constitutes, retarder is arranged in the valve body, retarder is fixed on the valve body by the retarder fixing frame, the bottom of valve body is by valve body bottom and the sealing of bottom seal ring, the wire outlet hole that the motor lines of drawing is arranged on the valve body bottom, this wire outlet hole is by outlet plug and outlet capping sealing, retarder one end links to each other with external power supply and control section by motor lines, the other end of retarder links to each other with screw rod by transfer wheel, screw rod passes lower half portion that valve body is stretched in the middle hole of valve body, the valve body top and the bottom are by screw rod capping and the airtight separation of y-shaped ring, the other end of screw rod links to each other with the nut that is fixed together with spool, one circular hole that is used for passing pin is arranged at the bottom of screw rod, the sealing gasket pressing plate is fixed on sealing gasket on the spool by fixed block, the ripple stuffing box gland fixes on the valve body together by valve land and fixed block, and the valve port fixture is fixed on the valve land.
The automatic control motor valve that this practicability is related, described fixed block is a screw.
The automatic control motor valve that the utility model is related has following beneficial effect: adopt valve-embeddedly to make that described autocontrol valve is novel, simple in structure, cheap, safe in utilization, easy operating.
Description of drawings
Fig. 1 is the internal structure schematic representation of automatic control motor valve,
Fig. 2 is an automatic control motor valve A-A cross-sectional view.
Embodiment
Automatic control motor valve of the present utility model is specifically described as follows in conjunction with Fig. 1 to Fig. 2: this automatic control motor valve is by retarder 3, valve body 1, valve port 12, sealing gasket 8, spool 13, screw rod 15 constitutes, retarder 3 is arranged in the valve body 1, retarder 3 is fixed on the valve body 1 by retarder fixing frame 4, the bottom of valve body 1 is by valve body bottom 10 and 2 sealings of bottom seal ring, the wire outlet hole that the motor lines of drawing is arranged on the valve body bottom 10, this wire outlet hole is by outlet plug 17 and outlet capping 18 sealings, retarder 3 one ends link to each other with external power supply and control section by motor lines, the other end of retarder 3 links to each other with screw rod 15 by transfer wheel 5, screw rod 15 passes lower half portion that valve body 1 is stretched in valve body 1 middle hole, valve body 1 top and the bottom are by screw rod capping 16 and y-shaped ring 6 airtight separations, the other end of screw rod 15 links to each other with the nut 14 that is fixed together with spool 13, one circular hole that is used for passing pin 19 is arranged at the bottom of screw rod 15, sealing gasket pressing plate 9 is fixed on sealing gasket 8 on the spool 13 by screw, ripple stuffing box gland 7 by valve land 11 and screw on valve body 1, valve port 12 by screw on valve land 11.
The working principle of the alleged automatic control motor valve of the utility model is as follows: the default conditions of valve are opening state, when system sends the instruction of closing valve, system sends instruction by the motor lines of motor, motor rotation, the retarder 3 of drive in valve body 1, after retarder 3 slows down moment is transferred to the output wheel shaft, the output wheel shaft drives screw rod 15 and rotates, screw rod 15 is delivered to spool 13 with action, and spool promotes sealing gasket 8 actions, when sealing gasket arrives valve port 12 specified positiones, because pressure adaptive makes sealing gasket 8 be out of shape, sealing gasket 8 distortion make valve closing, in this process, along with the distortion of sealing gasket 8, screw rod 15 is subjected to resistance, the running speed of screw rod 15 is more and more slower, and the electric current of motor is increasing thereupon, valve closing when electric current reaches certain numerical value, system sends instruction, cut off electric current, the motor stall is closed valve events and is finished.
Open valve events in contrast, principle is identical, does not do detailed description at this.
