Abstract

The utility model relates to a silencing check gate valve used on the outlets of the water supply system of high buildings and high-pressure hydraulic pumps. The silencing check valve comprises a check valve and a gate valve. The check valve is composed of a check valve housing and a turning plate hinged inside the check valve housing; the gate valve is composed of a gate valve housing and a lead screw gate; the check valve housing and the gate valve housing are directly connected together, and the outlet of the check valve housing is communicated with the inlet of the gate valve housing; the whole water face of the turning plate of the check valve is connected with a flexible silencing plate. The utility model has the advantages of low cost, easy maintenance, little space occupation, favorable silencing, checking, and stopping performances, and strong practicability.

Description

二合一止闸阀 Combo stop valve

本实用新型涉及一种用于高层建筑给水系统、高压水泵出口上的消声止回闸阀。 The present invention relates to a high-rise building water supply system for the high-pressure pump outlet muffler on non-return valve.

以往高层建筑给水系统及其它增压设备上都采用一只闸阀,一只单向阀通过法兰串连一起作为止回设施,这种连接安装较繁琐,费料费时,成本又高,维修不便,占用空间大,单向阀在水泵停机瞬间会遇到水倒流产生猛烈地撞击挡板造成噪声,还会出现水锤现象和强烈的震动。 Are conventionally employed high-rise building water supply systems and other equipment a pressurized valve, a check valve in series with a flange-check facilities, such a connection is relatively complex installation, material costs and time-consuming, and costly, maintenance inconvenience occupy a large space, getting to the water in the pump check valve will be shut down instantly produce back violently hits the paddle causing noise, water hammer phenomenon and there will be a strong vibration.

本实用新型的目的就是为了解决上述问题,提供一种造价低,易安装维修,占用空间小,消声止回、截止性能好,实用性强的二合一止闸阀。 The purpose of the present invention is to solve the above problems and to provide a low-cost, easy installation and maintenance, small footprint, muffler check, cut-off of good, practical combo stop valve.

本实用新型的技术解决方案:一种二合一止闸阀,它包括有止回阀和闸阀,止回阀由止回阀壳体和铰接其内的翻板组成,闸阀由闸阀壳体和丝杆闸门组成,其特征在于止回阀壳体和闸阀壳体直接连为一体,其止回阀壳体出口与闸阀壳体进口连通。 The present invention to solve the technical solutions: A two-in stop valve, comprising a check valve and a gate valve, check valve housing and the hinged flap in its composition, a gate valve housing and wire shutter bar composition, characterized in that the check valve is directly connected to one of its valve housing outlet in communication with the valve housing inlet and valve housing housing.

本实用新型将止回阀壳体和闸阀壳体直接连为一体,且止回阀翻板的迎水面整体连有柔性隔音板,故可有效地消除噪声,其造价低,易安装维修,占用空间小,消声止回、截止性能好,易普及推广,实用性强。 The present invention the check valve housing and valve housing directly connected together, and the positive side of the check valve flap integrally connected with a flexible insulation sheet, it can effectively eliminate the noise, its low cost, easy installation and maintenance, occupies small space, muffler check, good closing performance, easy popularization, and practical.

以下将结合附图对本实用新型作进一步说明。 In conjunction with the accompanying drawings will further illustrate the present invention for.

图1是本实用新型的结构示意图。 FIG. 1 is a structural diagram of the present invention novel.

如图1,本实用新型包括有止回阀和闸阀,止回阀由止回阀壳体1和铰接其内的翻板2组成,闸阀由闸阀壳体3和丝杆闸门4组成,本实用新型的特点是,止回阀壳体1和闸阀壳体3直接连为一体,其止回阀壳体1出口与闸阀壳体3进口连通。 1, the present invention comprises a valve and a check valve, the check valve housing 1 and hinged flap composed of 2 therein, a valve spindle and a valve housing 3 composed of the shutter 4, the present invention the new feature is that the check valve housing 1 and the housing 3 directly connected to the valve as a whole, an outlet 3 1 which is in communication with the inlet valve housing valve housing. 这样连接安装及维修方便,占用空间小,实用性强。 Such connection installation and easy maintenance, small footprint, practical.

本实用新型的止回阀中,其翻板2的迎水面整体连有柔性隔音板5,它们可以粘接为一体,也可通过螺栓和压条固连为一体,柔性隔音板5可采用橡胶板,石棉板等,最好采用高弹性多孔橡胶板。 A check valve in the present invention, the upstream face of the flap 2 which is integrally connected with a flexible insulation plate 5, which may be bonded integrally by a bolt and may be secured integrally layering, flexible insulation plate 5 may employ rubber sheet , asbestos, etc., preferably high elastic porous rubber plate. 这样阻止噪声、缓闭止回效果好,消除了水锤现象。 This prevents noise, slow closing check effect, eliminates water hammer phenomenon. 本实用新型的闸阀可以是普通螺杆式闸阀,也可是快速闸门式闸阀。 The valve of the present invention may be an ordinary screw type valve, the shutter-type valve may also be fast.
