Abstract
The utility model discloses a low-fluid resistance drain valve which comprises a valve body, a valve clack, a valve rod, a packing, a gland and a protective ring, wherein the valve clack, the valve rod, the packing, the gland an the protective ring are arranged in the valve body, the valve rod is positioned above the valve rod, the packing is arranged at the middle of the valve body, and a sealing group is arranged at the lower end of the valve body. The gland and the protective ring are fixed on the valve rod. The gland is positioned at the upper end of the packing, and the protective ring is positioned at the upper end of the gland. The valve body is of a Y-shaped structure. The low-fluid resistance drain valve has the beneficial effects the fluid resistance can be reduced by adopting the Y-shaped valve body, and the valve clack and a valve base which are sprayed with hard coatings made of satellite, the sealing property of the valve is ensured and the service life of the valve is prolonged.
Description
Technical field
The utility model relates to a kind of valve mechanism, especially a kind of low flow resistance drain valve.
Background technique
Drain valve is widely used in petrochemical industry, chemical industry, coal gas, rock gas, liquefied petroleum gas (LPG), HVAC industry and the general industry with characteristics such as simple in structure, that working stroke is little, and opening and closing time is short.The basic structure of general drain valve: rely on external force to give the pressure of valve rod, drive flap sealing surface and sealing surface of seat and fit tightly, stop the medium circulation, realize opening or closing, it is simple in structure that common drain valve adopts, the resistance of fluid is big, and the force rate that opening and closing need is bigger, when long-time running, because of resistance big, easy to wear, leak problem such as sealability is not good enough easily.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the utility model provides a kind of low flow resistance drain valve, makes valve be easy to open and close.
For achieving the above object, the technical solution adopted in the utility model is: a kind of low flow resistance drain valve comprises valve body and is in valve body interior flap, valve rod, filler, gland and guard ring.Valve rod is in the top of flap, and the valve body middle part is provided with filler, and the lower end is provided with sealing group.Gland and guard ring are fixed on the valve rod.Gland is in the upper end of filler, and guard ring is in the upper end of gland.Described valve body is y-type structure.
Preferably, described sealing group is made up of pad and lining, and lining is in the upper end of pad.
Preferably, fixedly there is drive unit the upper end of valve rod, comes the keying of existing valve.
Preferably, described flap and valve base inside all are sprayed with the hard coat of stellite, and this hard coat has good hardness and abrasion resistance properties, guarantee that valve seal is good, improve life of valve.
Preferably, described valve body is forging molding.
Preferably, for removably connecting, valve rod stretches out outside the valve body between valve rod and the flap.
Preferably, in the joint, upper end of valve rod and valve body, be provided with O type circle, guarantee sealing.
Preferably, be provided with exhaust port and row's grease holes in valve body chamber portion upper end, be used for eliminating and the regular maintenance of waste gas.
The utility model beneficial effect is: adopt above-mentioned Y valve body structure and be sprayed with flap and the valve seat of the hard coat of stellite, can reduce fluid resistance, guarantee the valve seal performance, improve life of valve.
