Problems solved by technology

However, there are still outstanding problems in the application of actual working conditions: in the high-pressure or medium-pressure environment, the noise of the valve is abnormally loud, and noise is also a kind of pollution. Working in a noisy environment for a long time will cause damage to the body of workers

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as figure 1 As shown, a silent throttling cut-off vent valve includes a valve body 1, a valve stem 5, a bracket, and a valve cover. 4. Baffle plate 6; the valve sleeve 4 is cylindrical, installed vertically on the same axis as the valve stem, and the lower circumference of the valve sleeve 4 is provided with at least one set of throttling grooves 9 of different lengths; the throttling The bottoms of the grooves 9 are on the same axis, and the throttling grooves 9 are distributed periodically and symmetrically; the baffle 6 is vertically arranged in the inlet passage of the valve body, and the baffle 6 is a hollow ring shape with openings on the circumferential surface. There are asymmetrical orifices. The valve disc assembly includes a valve disc 3 , a valve seat 2 , a pressure ring 7 and a soft sealing ring, and the valve disc 3 ...

Abstract

The invention discloses a mute throttling stop emptying valve, and belongs to the field of valves. The mute throttling stop emptying valve comprises a valve body, a valve rod, a bracket and a valve cover; a noise reduction component and a valve clack component are arranged in the valve body; the noise reduction component comprises a valve sleeve and a flow choking plate; the valve sleeve is cylindrical and is vertically mounted on the same axis as the valve rod; at least one group of throttling grooves with different lengths are formed in the circumference of the lower part of the valve sleeve; the bottoms of the throttling grooves are in the same axis; the throttling grooves are in periodic symmetrical distribution; the flow choking plate is vertically arranged in a channel in an inlet ofthe valve body; the flow choking plate is in a hollow annular shape; and asymmetric throttling holes are formed in the circumference surface. By adopting the mute throttling stop emptying valve, theproblem of noise of a throttling stop emptying valve is solved effectively.

Description

technical field [0001] The invention relates to the field of valves, in particular to a silent throttling cut-off venting valve. Background technique [0002] Throttle cut-off vent valve is a double-seal valve, which is mainly used in the transmission pipelines of oil, natural gas, coal gas, liquefied oil and gas, etc., and is usually used for regulating control or cutting off. This type of valve is a new throttling, cut-off, and venting product, with multi-stage throttling effects, obvious throttling effects, reliable sealing, and convenient operation and maintenance. [0003] Great progress has been made in the existing throttling cut-off and venting valves in terms of throttling, cutting off, setting of balance holes to reduce operating torque, combined sealing and the like. However, there are still outstanding problems in the application of actual working conditions: in a high-pressure or medium-pressure environment, the noise of the valve is abnormally loud, and noise ...
