Abstract

The utility model belongs to a lifting valve. The utility model provides a fluid valve with simple structure, convenient operation and good closing performance, and designs and manufactures a pressing and lifting type valve. The utility model comprises a handle, a valve rod, a valve cover, a sealing cushion ring, a valve body and a cone cylinder which is connected with the lower end of the valve body. The upper part of the cone cylinder is big, and the lower part of the cone cylinder is small. The inner cavity of the valve body is made into a hollow cavity whose size and shape are same with the cone cylinder. The hollow cavity is matched with the cone cylinder. The upper part of the valve rod and the inner cavity wall of the valve body are provided with an elastic sealing ring. The utility model adopts the method that the utility model is opened and closed by the pressing and lifting top and bottom. The use is convenient. The closing performance is good.

Description

Pressure valve

The utility model relates to a kind of poppet valve.

Existing Liquid valve comprises water tap, adopts rubber to make Sealing mostly, opens and closes liquid stream with screw rod through screwing.The valve of this structure can drive the rubber sheet gasket rotation when manipulating, damage rubber sheet gasket easily, makes valve be difficult to closure.Moreover rubber sheet gasket is in impaction state mostly and follows the string easily, does not have good obturation effect.Evaporating, emitting, dripping or leaking of liquid or gas appearred in regular meeting when in addition, this valve was gone back when opening.A kind of pressure-raising formula magnet valve is arranged, use the initial stage obturation effect good, but as water valve use from the beginning, some particulates in the water and iron rust can be adsorbed on the magnet automatically, make it to reduce even lose airtight effect, and adopt magnet to make Sealing, the processing technology complexity, product cost also increases thereupon.

The purpose of this utility model provides a kind of simple in structure, easy to use, obturation effect is good, cost is low valve.

For achieving the above object, the technical solution of the utility model is: this pressure-raising formula valve comprises handle, valve rod, valve gap, seal washer, valve body, the valve rod lower end connects up big and down small awl cylinder, body cavity is made the size shape cavity identical with said awl cylinder and is cooperated with the awl cylinder, between valve rod top and the body cavity wall elastic seal ring is housed.

The utility model adopts that conical closing face and pressure-raising formula valve rod are controlled, regulated fluid, and is easy to use, because valve fluid when closure can be executed a power that presses down to valve rod, so valve just closes tightly voluntarily once closure, obturation effect is good.

Further specify the technical solution of the utility model below in conjunction with drawings and Examples.

Fig. 1 is a pressure-raising formula profile valve schematic representation;

Fig. 2 is the pressure-raising formula profile valve schematic representation of another shape.

Embodiment 1: see Fig. 1, the utility model--pressure-raising formula valve comprises handle 1, valve rod 2, valve gap 3, seal washer 4, valve body 5, the valve rod lower end connects up big and down small awl cylinder 6, valve body 5 inner chambers are made the size shape cavity identical with awl cylinder 6 and are bored cylinder 6 and cooperate, between valve rod 2 tops and the body cavity wall elastic seal ring 4 is housed, valve body 5 is made for the shape that fluid inlet and outlet changes direction.

Embodiment 2: see Fig. 2, and the pressure-raising formula valve of present embodiment, valve body 5 is made for the constant shape of fluid inlet and outlet direction, and other structure is identical with embodiment 1.

Claims

1, a kind of pressure-raising formula valve, comprise handle (1), valve rod (2), valve gap (3), seal washer (4), valve body (5), it is characterized in that, valve rod (2) lower end connects up big and down small awl cylinder (6), valve body (5) inner chamber is made the size shape cavity identical with awl cylinder (6) and is cooperated with awl cylinder (6), and elastic seal ring (4) is housed between valve rod (2) top and the body cavity wall.
