Abstract
The utility model discloses a lifting check valve capable of being mounted at any angle. The lifting check valve comprises a valve body, a gland, a valve rod, a valve clack and a spring, wherein the valve clack is fixedly connected to the valve rod, and both the left end and the right end of the valve rod are supported on the valve body through shaft sleeves in a sliding manner. In the utility model, as the bidirectional guiding support manner is adopted, the valve rod can not be jammed no matter at what angle the lifting check valve is mounted; the valve clack adopts a cone-shaped flat head design, and the valve body adopts a waist drum-shaped design to improve the flow direction of media, so that the flow resistance coefficient is lowered; and a skeleton type rubber seal ring directly embedded into the valve clack prevents the media from scouring the valve clack for a long time, so that the service life of the valve is obviously prolonged, and solidness and durability are ensured.
Description
Technical field
The utility model relates generally to a kind of lift check valve, particularly a kind of lift check valve that can arbitrarily angled installation.
Background technique
Safety check belongs to the self-acting valve class, is mainly used on the pipeline of medium one-way flow, and its function is only to allow medium to flow to a direction, in case have an accident.By the structure branch, can be divided into three kinds of lift check valve, Swing check valve and butterfly check valves, at present, Lift check valve can be divided into vertical and horizontal two kinds.
As shown in Figure 2, in the prior art, lift check valve comprises valve body 21, gland 22, valve rod 23, flap 24, spring 25 and axle sleeve 26, and described valve rod 23 1 ends are fixedlyed connected with flap 24, and the other end adopts the axle sleeve sliding support on described valve body 21.Only an end is supported owing to valve rod 21, therefore Vertical Lift Check Valves can only be installed in the vertical pipe, and horizontal check valve can only be installed in the horizontal pipe, otherwise valve rod is under the pressure effect of self gravitation or flowing medium, the phenomenon of clamping stagnation in valve body then may occur, thereby cause the safety check cisco unity malfunction.
The model utility content
The technical problems to be solved in the utility model provide a kind of can arbitrarily angled installation and flow resistance is little, the lift check valve of long service life.
For solving the problems of the technologies described above, the technological scheme that the utility model adopted is:
A kind of capable of arbitrary angle mounting lift check valve comprises valve body, gland, valve rod, flap, and spring is characterized in that: described flap is fixed on the valve rod, and two ends, the described valve rod left and right sides all adopt the axle sleeve sliding support on described valve body.
Described flap is the tack taper; Described valve body is dolioform; Directly be inlaid with skeleton rubber seal on the described flap.
Because the utility model adopts two-way guiding to support, arbitrarily angled installation valve rod all can not occur by the phenomenon of jam, and the stability of its keying is improved greatly, and sealing reliably strengthens greatly; Described flap adopts " cone " shape cab-over design, and valve body adopts " waist drum " exterior design, improve MEDIA FLOW to, thereby reduced flow resistance coefficient; And the flap outer surface directly is inlaid with skeleton rubber seal, thereby has avoided medium for a long time to directly the washing away of flap, and obviously prolong working life, sturdy and durable.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structural representation of capable of arbitrary angle mounting lift check valve described in the utility model.
Fig. 2 is the structural representation of lift check valve in the prior art.
Embodiment
As shown in Figure 1, a kind of capable of arbitrary angle mounting lift check valve, comprise valve body 11, gland 12, valve rod 13, flap 14 and spring 15, described flap 14 is fixed on the valve rod 13, and two ends, described valve rod 13 left and right sides all adopt axle sleeve 16 sliding supports on described valve body 11; Described flap 14 is the tack taper, directly is inlaid with skeleton rubber seal 17 on it, and described valve body 11 is dolioform.
Lift check valve described in the utility model is owing to adopt two guiding to support, be that two ends, valve rod 13 left and right sides all adopt axle sleeve 16 sliding supports on described valve body 11, nonmetal lubricative axle sleeve 16 is housed between the axis of guide and the front and back leading truck, flap 14 liftings are flexible, can not produce locking phenomenon, can not make valve rod 13 clamping stagnation in valve body 11 in the use, cause the phenomenon of described safety check cisco unity malfunction to take place because of the variation of setting angle.
Described flap 14 is the tack taper, and described valve body 11 is dolioform, this valve body structure can improve MEDIA FLOW to, reduce flow resistance coefficient, loss of head is little.Directly be inlaid with skeleton rubber seal 17 on the flap, stability is improved greatly, can reach good sealing effect, avoided medium for a long time to directly the washing away of flap, obviously prolong working life, sturdy and durable.
