Abstract
The invention relates to a pressure release valve of a gear pump. The pressure release valve comprises a valve body (1), a valve sealing part (2), a pressure spring (3), a piston (4), a safety pin (5), adjusting nuts (6), a valve deck (7) and an O-shaped ring (8). The invention particularly relates to application of the gear pump (a positive displacement pump) during conveying so that the gear pump can be prevented from being damaged when a pipeline is blocked or a separation valve is accidentally closed. A spring type pressure-adjustable structure is adopted through innovative design, it is ensured that a safe pressure release function is achieved on the gear pump, the stable pressure of an outlet end is also ensured, the pressure release valve winds around an outlet pipeline and winds back to a liquid supply source through a bypass, and therefore the safety of a system and the pump gear is ensured; and efficiency is improved, the service life is prolonged, the defects of the prior art are overcome, and the requirement for wide application in the fields of tobaccos, petroleum, the chemical industry, pharmacy, food, beverages, papermaking, laboratories, chemicals and the like is met.
Description
Technical field
The present invention relates to a kind of Decompression valves of gear pump, comprise valve body (1), valve seal (2), pressure spring (3), piston (4), safety pin (5), adjusting nut (6), valve gap (7), O type circle (8), in particular to application when carrying gear pump (positive-displacement pump), with prevent gear pump when line clogging or separating valve is surprisingly cut out be damaged.
Background technique
The application of gear pump in the market selects separating valve to be arranged on the entrance end of gear pump substantially, but system pressure as change or line clogging and separating valve are surprisingly closed when, so just can not guarantee that the pressure of output terminal is the pressure that application needs, thus cause the instability of system, even may produce danger and unnecessary injury is caused to personnel.
Summary of the invention
In order to overcome the deficiency of current technology, the present invention relates to a kind of Decompression valves of gear pump, the structure of spring adjustable pressure is adopted by innovative design, guarantee the decompression function giving a gear pump safety, also ensure that the pressure that outlet end is stable, Decompression valves is walked around outlet conduit and is rapped around in supply fluid supply by bypass, and this ensures that there the safety of system and gear pump, technological scheme of the present invention is as follows.
A kind of Decompression valves of gear pump, it is characterized in that: valve seal (2) is loaded in valve body (1), and it is inner that pressure spring (3) is loaded valve seal (2), piston (4) is loaded valve body (1) inner, and safety pin (5) is locked; Be contained in by adjusting nut (6) on valve body (1), O type circle (8) is contained on valve body (1), and covers valve gap (7).
Valve body (1), valve seal (2), pressure spring (3), piston (4), safety pin (5), adjusting nut (6), valve gap (7), O type circle (8) is all provided with plurality of specifications and can forms different series.
As shown from the above technical solution, the advantage of the Decompression valves of gear pump of the present invention is remarkable: the structure being adopted spring adjustable pressure by innovative design, guarantee the decompression function giving a gear pump safety, also ensure that the pressure that outlet end is stable, Decompression valves is walked around outlet conduit and is rapped around in supply fluid supply by bypass, this ensures that there the safety of system and gear pump, improve efficiency, extend the life-span, the deficiencies in the prior art are filled up, meet tobacco, oil, chemical industry, pharmacy, food, beverage, papermaking, the extensive use in the field such as laboratory and chemical product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Appointment Fig. 1 is Figure of abstract, wherein: valve body (1), and valve seal (2), pressure spring (3), piston (4), safety pin (5), adjusting nut (6), valve gap (7), O type circle (8).
