Abstract
Provided is a leak testing detector for an ammonia pump check valve. The leak testing detector for the ammonia pump check valve mainly comprises a pressure cylinder body. The upper end of the pressure cylinder is provided with a seal head. The lower end of the pressure cylinder is an opening. The seal head is provided with a filling pipe end and exhaust pipes. The exhaust pipes are communicated with the inner side of the cylinder body. The exhaust pipes are provided with an exhaust valve. A through hole is arranged in the middle of the seal head. A connecting screw penetrates through the through hole. The lower end of the connecting screw is arranged inside the cylinder body and the upper end of the connecting screw is arranged on the upper portion of the seal head. A nut is arranged on the portion of the connecting screw and the portion is on the upper portion of the seal head. Small seal washers are arranged between the nut and the seal head. By utilizing the leak testing detector, the leak testing of the check valve of the ammonia pump can be realized at the two directions, thereby better ensuring the reliability of the ammonia pump check valve when in use and guaranteeing the normal use of the ammonia pump ultimately.
Description
Technical field
The utility model relates to the service technique field of ammonia pump retaining valve, particularly relates to a kind of ammonia pump retaining valve leak test detecting device.
Background technology
Ammonia pump is generally used in chemical fertilizer production enterprise, and in use the ammonia pump fault of not looking up and down frequently takes place, and each repair time is long, has wasted many man-hours, and has reduced production efficiency.We think that through research the sealing reliability problem of retaining valve is one of pump key factor of not looking up and down.
The leak test of ammonia pump retaining valve adopted the method for full water test originally always in the workshop.But the method easy detection of this kind leak test go out retaining valve with the equidirectional flow direction of material on the situation of whether leaking.But whether retaining valve leaks on opposite direction can't detect.Retaining valve in actual use if with the reverse direction of flow direction of material on poorly sealed, then can cause when plunger to swivel motion, when material was inhaled into from inlet one-way valve, the material of pump cylinder block inner high voltage side took place by the phenomenon of outlet retaining valve to the low-pressure side adverse current.Finally cause pump to look fluctuation up and down, even do not look up and down.
The utility model content
The purpose of this utility model is in order to address the above problem, to provide a kind of.
The technical solution of the utility model is: a kind of ammonia pump retaining valve leak test detecting device, its main body is a pressure cylinder, there is end socket the upper end of this pressure cylinder, the lower end is uncovered, described end socket is provided with water filling port, gas outlet is communicated with inner barrel, described gas outlet is provided with drain tap, middle part at end socket is provided with through hole, establish in this through hole and be installed with connecting screw rod, this connecting screw rod lower end is positioned at cylindrical shell, the upper end of this connecting screw rod is positioned at end socket top, and the part on end socket top of connecting screw rod is equipped with nut, is provided with little packing washer between nut and end socket.
The edge of the lower end of described pressure cylinder is provided with big packing washer.
The sidewall of described pressure cylinder is externally connected with handle.
The size match of the caliber size of described lower end and detected retaining valve.
The lower end of described connecting screw rod is connected with gasket seal.
The beneficial effects of the utility model
After having adopted this leak test appliance, make the retaining valve of ammonia pump can both detect leak test at both direction.So just well guaranteed ammonia pump retaining valve reliability in use.The normal use of the final ammonia pump that guarantees.
Practice proves really that also after having used this leak test detecting device, the repair time of ammonia pump shortened to average about 2 hours by original average 4 hours, and the repair time shortens dramatically.The economic benefit measuring and calculating: do not look problem maintenance 10 time, each average 4 hour because of the 2#3# pump every year.After having used this ammonia pump retaining valve leak test detecting device, shorten to 2 hours by mean time to overhaul; An ammonia pump whenever stops to influence in 1 hour 11 tons of urea productions, 1500 yuan of meters of ton urea cost.The then annual increasable output value is 330,000 yuan.
